Abstract Inborn errors of metabolism (IEM) are a group of rare diseases that cause high morbidity and mortality. The objective of the present study was to describe the clinical-biochemical profile of patients, under 15 years old, with IEM not included in newborn screening, in a pediatric hospital, from January 2008 to December 2018. A descriptive and retrospective study was carried out in which hospital records were evaluated: reason for consultation, diagnosis, clinical evolution, diagnostic times and costs of patients with suspected and confirmed diagnosis of IEM between 2008 and 2018 in a public pediatric hospital from Mendoza, Argentina. A total of 59 patients with IEM were evaluated: lysosomal storage diseases (32.2%) and metabolic alteration of amino acids and organic acidurias (27.1%), among others. The mean age was 2.6 years and the male/female ratio was 1.5. The mean time between the first consultation for suspected IEM and diagnosis was 11 months. There was correspondence between the diagnosis and the reason for consultation (p=0.003). Twenty-two percent evolved to progressive deterioration, 25.4% remained stable, 28.8% with sequelae and 23.8% died. The total direct cost of the biochemical tests was 61 560 UB=1 809 248 Argentine pesos=46 785 US dollars (value at the end of 2018). Concluding, this work reflects the variability of IEM and its clinical evolution, similar to what has been published, and the local biochemical profile.

Testes bioquímicos para identificação de leveduras na medicina veterinária - revisão de literatura / Biochemical tests to yeast identification in veterinary medicine - literature review / Pruebas bioquímicas para identificación de levaduras en la medicina veterinaria - revisión de literatura

As leveduras são fungos de importância à medicina veterinária por causarem doenças infecciosas em diferentes hospedeiros animais. A presente revisão de literatura teve como objetivo relatar os principais testes bioquímicos capazes de auxiliar na identificação de fungos leveduriformes de interesse veterinário e zoonótico. Para o levantamento bibliográfico, foram consideradas 48 publicações científicas selecionadas na área e indexadas nas principais bases de dados, entre os anos de 1988 e 2020. Como resultados, observou-se que oito provas são as mais empregadas na rotina micológica. Devido à baixa variabilidade morfológica das espécies leveduriformes, testes bioquímicos complementares são fundamentais na rotina laboratorial. A análise do perfil bioquímico de leveduras contribui na determinação taxonômica dos fungos a partir de reações químicas, visto que o metabolismo varia de acordo com a espécie, resultando em metabólitos distintos, os quais podem ser avaliados por diferentes provas. Conclui-se que a identificação fenotípica das leveduras é imprescindível no diagnóstico, prognóstico, tratamento e controle de doenças fúngicas e contribui para a manutenção da saúde animal.(AU)

Yeasts are fungi of importance to veterinary medicine because they cause infectious diseases in different animal hosts. This literature review aimed to report the main biochemical tests capable of assisting in the identification of yeast-like fungi of veterinary and zoonotic interest. For the bibliographical survey, 48 selected scientific publications in the area and indexed in the main databases, between the years 1988 and 2020, were considered. As a result, it was observed that eight tests are the most used in the mycological routine. Due to the low morphological variability of yeast species, complementary biochemical tests are fundamental in the laboratory routine. The analysis of the biochemical profile of yeast contributes to the taxonomic determination of fungi based on chemical reactions, since the metabolism varies according to the species, resulting in different metabolites, which can be evaluated by different tests. It is concluded that the phenotypic identification of yeasts is essential in the diagnosis, prognosis, treatment and control of fungal diseases and contributes to the maintenance of animal health.(AU)

Clinical and Biochemical Profile of Hepatitis A Virus infection in Children

Background: Acute hepatitis A virus infection in children in developing countries is a matter of concern though the incidence has come down in developed countries.To observe the clinical presentation and biochemical profile of hepatitis A virus infection in children hospitalized in a tertiary care center in Bangladesh.Material & Methods:In this cross-sectional observational study, data were collected from the records of pediatric patients who were admitted due to acute hepatitis. Demographic data were collected, and complete physical examination findings and laboratory data were also taken. Serum samples were tested for LFT, Anti-HAV IgM and other viral markers among them Anti-HAV IgM positive children were included in the study.Results:Among the total of 40 patients suffering from Acute Viral Hepatitis (AVH), male predominated over female with 57.5% vs. 42.5%. The majority of the study population (65%) came from the urban area. In this study, 65% of the patients used tap water and 35% used tube well water for drinking purposes while the majority 70% used boiled water. Most of the patients (80%) consumed both homemade and outside foods and drinks while 20% consumed only homemade food. Positive family history of viral hepatitis was found in 12.5% of cases. Common presentations were fever (100%), jaundice (100%), anorexia, nausea (95%), vomiting (85%), abdominal pain (50%) etc. On examination Jaundice (100%) and hepatomegaly (95%), splenomegaly (5%), and ascites (7.5%). Only 7.5% of patients developed complications like cholestasis,7.5% showed ascites,5% had relapsed and 2.5% develop liver failure.Conclusions:This study showed that poor sanitation and poor hygiene are the main risk factors for hepatitis A. The common presenting features which should alert the clinicians include fever, jaundice, anorexia, nausea, vomiting, diarrhea, abdominal distension, hepatosplenomegaly and ascites. In Bangladesh, safe water supplies and proper sanitation will constitute the best solution to eliminate endemic hepatitis A.

A study of the biochemical profile and its correlation with Alcohol Dependence: a hospital based study

Background: The aim of the research was to study the biochemical profile of the male patients diagnosed with alcohol dependence syndrome and its correlation with the severity of dependence. Methodology: A descriptive study comprising of 60 patients admitted in the psychiatry de-addiction clinic at HSK hospital from 1st July 2017 to 31st December 2017 was done after taking institutional ethical committee clearance. A semi-structured proforma was used to determine the socio-demographic details like education, occupation, socio-economic status etc. the severity of dependence was determined using Severity of Alcohol Dependence Questionnaire (SADQ) scale and basic biochemical tests were performed. Descriptive analysis using an appropriate statistical test was done. Results: The mean age at presentation was 37.9 years. Out of 60 patients, 21 (35%) had mild dependence, 24 (40%) had moderate dependence and 15 (25%) had severe dependence. Hepatic enzymes AST and ALT were raised in 76.67% and 66.67% patients respectively. AST to ALT ratio was above 2 in 11.67% patients. There was a significant correlation between total SADQ scores and Alanine Transaminase (? = 0.281, P = 0.03, n = 60). Conclusion: The biochemical tests were deranged in most of the patients with alcohol dependence. Certain markers can be developed based on their significant association with the dependence levels, thus, helping in early diagnosis and prevention of alcohol dependence syndrome

Effect of a phytogenic feed additives mixture on milk physico-chemical properties and biochemical parameters of Holstein cows / Efeito de uma mistura de aditivos fitogênicos alimentares nas propriedades físico-químicas do leite e parâmetros bioquímicos de vacas leiteiras da raça holandês

ABSTRACT: This study aimed to analyze the effect of phytogenic additives based on cardol, cardanol, and ricinoleic acid on the physico-chemical qualities and biochemical parameters of Holstein cow milk. Nineteen animals were divided into the control (GI) and treatment (GII) groups. Prior to the beginning of the experiment, sodium monensin was removed from the feed provided to the animals. This study consisted of two phases. In the first, animals from GI received the standard diet, without additives, while animals from GII received the standard diet supplemented with 10 g of phytogenic additives for 60 days. At the end of the first stage, the animals remained 30 days without receiving additives and in the second phase the groups were inverted, and the GII again received the phytogenic additive during the subsequent 60 days. Physical-chemical analyzes of milk were performed at moments 0, 15, 30, 45 and 60 days of the experiment and the blood parameters at times 0 and 60 days of the experiment were evaluated. There was no significant difference for the treatment x time interaction in any of the variables, but there was a trend between groups for the CCS parameter and there was a statistical difference for the protein, as well as for the AST. In this study it is observed that the addition of phytogenic additive modulating rumen fermentation based on cardol, cardanol and ricinoleic acid does not compromise, in general, the quality of milk, with positive results for some specific parameters such as protein content and aminotransferase.

RESUMO: Esse estudo teve por objetivo avaliar o efeito de um aditivo fitogênico a base de cardol, cardanol e ácido ricinoléico na qualidade físico-química do leite e perfil bioquímico de vacas da raça Holandês. Dezenove animais foram divididos em dois grupos: Grupo Controle (GI) e Grupo Tratado (GII). Previamente ao início do experimento, retirou-se a monensina sódica da ração fornecida aos animais. Este estudo consistiu de duas fases, sendo que na primeira fase, os animais do GI receberam a dieta padrão, sem aditivos, enquanto os animais do grupo GII receberam a ração padrão suplementada com 10 g dos aditivos fitogênicos durante 60 dias. Ao final da primeira etapa, os animais permaneceram 30 dias sem receber aditivos e na segunda fase os grupos foram invertidos, sendo que o GII novamente recebeu o aditivo fitogênico durante os 60 dias subsequentes. Foram realizadas análises físico-químicas do leite nos momentos 0, 15, 30, 45 e 60 dias do experimento e avaliados os parâmetros sanguíneos nos momentos 0 e 60 dias do experimento. Não se observou diferença significativa para a interação tratamento x tempo em nenhuma das variáveis, mas tendência entre grupos para o parâmetro de CCS, e houve diferença estatística para a proteína, assim como para a AST. Neste estudo observa-se que a adição de aditivo fitogênico modulador de fermentação ruminal a base de cardol, cardanol e ácido ricinoléico não compromete, de forma geral, a qualidade do leite, tendo resultados positivos para alguns parâmetros específicos como teor de proteína e aspartato aminotransferase.

Comparison of Serum Biochemical and Mineral Profiles of Cattle Reared Under Island and Coastal Ecosystem

The present study was conducted in the Department of Animal Reproduction Gynaecology and Obstetrics, College of Veterinary Science and Animal Husbandry, OUAT, BBSR in collaboration with ICAR-Central Island Agricultural Research Institute, Portblair (Andaman and Nicobar Island). Crossbred cattle with the history of anoestrus and repeat breeding were considered for the present investigation. The basic difference in serum biochemical and mineral profiles of cattle reared under two quite different ecosystems namely Island and coastal ecosystem was estimated which might be due to the variability in rainfall, ambient temperature, day light length and humidity. The incidence of different infertility conditions in both the ecosystems also might vary as per the environment. Serum samples were collected for estimations of biochemical parameters like total protein, glucose, cholesterol, Ca, P and Ca:P ratio. The overall incidence of infertility was recorded to be 47.62 % in island and 45.90 % in coastal ecosystem. No significant difference in serum levels of total protein, glucose, cholesterol, zinc, copper and manganese could be observed in between cattle reared in both ecosystems. It was concluded that the variations in humidity, ambient temperature, rain fall and day light length between Portblair, Andaman and coastal climate of Odisha, did not have much effect on reproduction of cattle

Effect of Eugenia jambolana and Psidium guajava Leaf Meal Mixture Supplementation on Performance, Biochemical Profile and Histopathological Changes of Broiler Chicks

Present study was undertaken in 120 day-old broiler chicks, randomly distributed into 4 dietary treatments (T1, T2, T3 and T4 supplemented with leaf meal mixture (LMM) of Eugenia jambolana and Psidium guajava @ 0, 2.5, 5.0 and 7.5 % of diet, respectively) each having 3 replicates (10 chicks/ replicate) in a complete randomized block design (CRD). Experimental chicks were fed basal diets (starter and finisher) supplemented with graded levels of LMM. Feed intake, body weight gain and feed conversion ratio (FCR) were recorded at weekly intervals. Two birds from each replicate were slaughtered at the end of feeding trial (42 days). Blood samples were collected and serum separated for biochemical profiles. For histopathological examination, representative tissue samples were collected in 10% neutral buffer formalin and then processed for paraffin embedding employing alcohol as dehydrating agent and xylene as clearing agent. Sections were cut at 4-5µm thickness and stained by routine haematoxylin and eosin method. On histopathological examination of liver, kidney, heart and intestine of T1 and T2 groups showed normal integrity, mild to moderate histopathological changes in T3 group, while, T4 showed drastic histopathological changes. It was concluded that E. jambolana and P. guajava LMM supplementation (2.5% or even 5%) maintained birds performance, minor histopathological changes and producing healthy low cholesterol broiler meat. The LMM incorporation (2.5%) in the diet of broiler chicks may be recommended as socioeconomic, alternative functional feed resource

Clinico-biochemical profile of chronic kidney disease patients in elderly age group in a tertiary care centre

Background: Chronic kidney disease (CKD) remains one of the major health problems in India. Renal function steadily deteriorates as age advances and advancing age has been indicted to have adverse implications in the disease progression to end stage renal disease (ESRD). With the present study, clinico-biochemical profiling of chronic kidney disease patients in geriatric age group as well as comparison with non-elderly patients was undertaken.Methods: In this cross-sectional observational study, 100 patients of CKD admitted in the tertiary care study centre were enrolled consecutively and assessed for symptoms, signs and biochemical parameters over two years. Study subjects were divided into two groups:- Group 1: Elderly patients- aged 60 years or more, and Group 2: Non-elderly patients- less than 60 years of age. Relevant comparisons were drawn statistically and tested for significance.Results: Pallor and pedal edema were observed to be the commonest clinical features across groups. Elderly group shows higher prevalence of severe anaemia (mean hemoglobin- 7.4 gm%). Higher prevalence of clinical and biochemical derangement was found in patients with relatively lower GFR. Elderly age group also had more prevalence of electrolyte abnormalities compared with non-elderly population, with statistically significant difference observed for hyponatremia (p value- 0.023), hypoproteinemia (p value- 0.0078) and blood urea level (p value- 0.0054).Conclusions: Understanding beforehand the biochemical abnormalities associated with old age in CKD patients helps in appropriate modifications in patient management.

Comparação dos parâmetros bioquímicos entre gestação única e gemelar de ovelhas da raça Dorper durante gestação, parto e pós-parto / Comparison of biochemical parameters between single and twin pregnancies of Dorper breed ewes during gestation, lambing and postpartum

Nas ovelhas, a demanda de nutrientes aumenta durante a gestação, especialmente nas últimas seis semanas, quando ocorre maior desenvolvimento do feto. Os objetivos deste trabalho foram estudar o perfil bioquímico de ovelhas durante a gestação e no periparto imediato, comparando-se gestação única com gemelar. Foram utilizadas 60 ovelhas, Dorper, divididas em dois grupos experimentais com base no diagnóstico de gestação ultrassonográfico: grupo 1: 30 ovelhas com feto único; grupo 2: 30 ovelhas com gestação gemelar. Em nove momentos de coleta, foram mensurados no soro sanguíneo: ureia, creatinina, proteína total (PT), albumina, globulina, aspartato aminotransferase (AST), gamaglutamiltransferase, fosfatase alcalina, colesterol e triglicérides. O peso vivo das ovelhas do G2 foi maior que do G1 em todos os momentos, inclusive quando estavam vazias. Houve diferença entre as ovelhas do G1 e do G2 nos valores de PT, albumina, AST e triglicérides. A partir de 120 dias de gestação, o perfil proteico se modificou, com menores níveis de ureia, PT, albumina e globulina, mostrando que a demanda metabólica se intensificou no último mês da gestação. Os níveis de colesterol e triglicérides diminuíram de 140 dias de gestação para o parto. Este trabalho mostrou que a gestação proporcionou mudanças significativas no metabolismo da ovelha, principalmente no terço final da gestação, quando há maior necessidade de acompanhamento para evitar a incidência de doenças metabólicas.(AU)

In sheep, nutrient demand increases during gestation, particularly in the last six weeks, when the fetuses develop. The objectives of this study were to evaluate the biochemical profile of ewes during pregnancy and in the immediate peripartum comparing single with twin pregnancies. Sixty ewes of Dorper breed were divided into two groups by pregnancy ultrasonographic diagnosis: 1 - 30 ewes with single fetus gestation; 2 - 30 ewes with twin pregnancy. In nine collection moments the following parameters were measured: urea, creatinine, total protein (TP), albumin, globulin, aspartate aminotransferase, gamma glutamyltransferase, alkaline phosphatase, cholesterol and triglycerides. The weight of G2 sheep was higher than G1 since they were empty. There were differences in G1 and G2 sheep metabolism in TP, Albumin, AST and Triglycerides. From 120 days of pregnancy, the protein profile changed, with lower levels of urea, TP, albumin and globulin, showing that the metabolic demand intensified in the last month of pregnancy. The levels of cholesterol and triglycerides decreased from 140 days of pregnancy to lambing day. This study showed that gestation provided significant changes in the ewe's metabolism, especially in the final third of gestation, when there is a greater need to follow the animals to avoid the incidence of metabolic diseases.(AU)

Changes in Biochemical Profile of Superovulated Sahiwal Cows through Hormonal Manipulation at Mid Luteal Phase of Estrous Cycle

In the present study, insulin and insulin-like growth factor-I (IGF-I) administered during mid-luteal phase of the estrous cycle and effect on biochemical profiles of Sahiwal donor cows was noted. Altogether eighteen cows (n=18) were selected and divided into 3 groups; control (n=6, untreated), T-I (n=6, Insulin-treated) and T-II (n=6, IGF-I treated). Superovulatory treatment was started on day 9th of the estrous cycle. With the 6th dose of FSH, prostaglandin was injected to induce superovulatory estrus. The superovulated cows were bred and superovulatory response of each animal was recorded. The collections of embryos were done non-surgically on the 7th day of superovulatory estrus. About 15 ml blood without anticoagulant was collected on days 5,7,9,11,13,15,17,19 and 21st or day of embryo recovery where day 0 of estrous cycle was taken as the day of estrus. Serum was separated, centrifuged at 3000 rpm for 15 minutes and transferred into sterilized serum vials. All samples were stored at -20 oC till analysis. Serum glucose, cholesterol, total protein, urea, and creatinine were estimated by Span Diagnostic Kits. The concentration of serum glucose increased significantly in insulin-treated and IGF-1 treated Sahiwal donor cows. It may be concluded that exogenous insulin and IGF-1 administration during mid-luteal phase may be helpful in follicular and embryonic development by increasing the level of serum glucose. The concentration of serum cholesterol, total protein, urea, and creatinine remains unaffected

Biochemical profile in dairy cows with artificial induction of lactation / Perfil bioquímico de vacas leiteiras submetidas a indução artificial de lactação

The objective of this study was to determine the biochemical profile of dairy cows with induced lactation. For comparison, another group of normally calved cows was used as control. Lactation was induced in multiparous Holstein cows (n=10) with two norgestomet implants (3mg each implant) on day 1. The testing continued with intramuscular norgestomet (3mg/animal) on days 1, 3, 5, 7, 9, 11, 13 and 15. On days 1, 9, 16 to 18 and then every 14 days, bSTr (500mg/animal) was added. On day 16, the intravaginal implant was removed and intramuscular prostaglandin F2α (0.530mg/animal) and intramuscular estradiol benzoate (5mg/animal) were added. On days 16 to 18 dexamethasone (10mg/animal) was added, and from days 18 to 20 intramuscular metoclopramide (100mg/animal) was added. Milking began on day 19 of the induction. Blood was collected for a biochemical profile after 21 days in milk. It was found that urea and triglyceride concentrations were significantly higher in the induced cows (P<0.05). Therefore, it was concluded that the animals that had lactation induced did not present disorders related to the biochemical profile indicating that the hepatic function, renal function and lipidogram of the animals were not affected by the use of the drugs to induce lactation.(AU)

O objetivo deste estudo foi determinar o perfil bioquímico de vacas leiteiras com submetidas a indução de lactação. Para comparação, outro grupo de vacas que apresentaram parto normal foi usado como controle. A lactação foi induzida em vacas Holandesas (n=10) utilizando dois implantes de norgestomet (3mg cada implante) no dia 1. O protocolo continuou com a aplicação de norgestomet intramuscular (3mg / animal) nos dias 1, 3, 5, 7, 9, 11, 13 e 15. Nos dias 1, 9, 16 a 18 e depois a cada 14 dias, foi adicionado bSTr (500mg / animal). No dia 16, o implante intravaginal foi removido e adicionou-se prostaglandina F2a intramuscular (0,530 mg / animal) e benzoato de estradiol intramuscular (5mg / animal). Nos dias 16 a 18 foi adicionada dexametasona (10mg / animal) e dos dias 18 a 20 foi adicionada metoclopramida intramuscular (100 mg / animal). A ordenha começou no dia 19 da indução. O sangue foi coletado para mensuração do perfil bioquímico após 21 em leite. Verificou-se que as concentrações de ureia e triglicérides foram significativamente maiores nas vacas induzidas (P<0,05). Portanto, concluiu-se que os animais que tiveram a lactação induzida não apresentaram distúrbios relacionados ao perfil bioquímico, indicando que a função hepática, a função renal e o lipidograma dos animais não foram afetados pelo uso das drogas para induzir a lactação.(AU)

For the evaluation of serum biochemical parameters of Pêga breed donkeys (Equus asinus), for the different age groups and sex, blood samples of 123 animals were analyzed, of 29 males aged from 8 days to 10 years and of 94 females (15 lactating) aged from 2 days to 12 years, from two farms in the central-southern Minas Gerais, Brazil. The donkeys were divided by age into 5 groups: Group 1 (≤6 months), Group 2 (7-12 months), Group 3 (13-48 months), Group 4 (49-72 months), and Group 5 (≥73 months). According to the sex, they were divided into two groups, males and females. Serum biochemical elements: total protein, albumin, globulin, the A:G ratio, cholesterol, triglycerides, uric acid, creatinine, urea, phosphorus, calcium, Ca:P ratio, magnesium, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and creatine kinase (CK), were evaluated in all animals. No significant differences were found for globulins, uric acid, urea and A:G ratio between age groups. Group 4 showed the highest values for total protein when compared with animals in Group 1 and 2. In Goup 2, the donkeys showed albumin levels lower than Group 3 and 4. Group 1 they had cholesterol levels higher than those in Group 2 and 4, and similar of the other groups. Higher phosphorus serum concentration was observed in Group 1. Calcium was significantly lower in Group 2. The Ca:P ratio was higher for Group 5. The magnesium values were significantly higher in donkeys older than 49 months (Group 4 and 5). The value of AST was lower for group 1. The ALP enzyme was significantly higher in younger animals up to 12 months, followed by gradual decrease with advancing age. The values of GGT were higher in donkeys up to 6 months, followed by decreasing values for subsequent groups. No differences were found between genders for albumin, cholesterol, creatinine, urea, uric acid, Ca:P ratio, magnesium, ALT, AST, and alkaline phosphatase. Females had higher values for total protein, globulin and triglycerides. Males showed higher values for A:G ratio, phosphorus, calcium and CK. The results showed that age and sex can influence serum biochemical values of Pêga breed donkeys.(AU)

Clinical, blood gas and biochemical profile of diarrheic dairy calves fed starter concentrate containing citrus pulp as a replacement for corn / Perfis clínico de gás sanguíneo e bioquímico de bezerros leiteiros diarreicos alimentados com concentrado inicial contendo polpa cítrica como substituto de milho

The objective of this study was to evaluate clinical signs, gas analysis, and metabolic effects of diarrhea in milk-fed calves consuming starter feed containing citrus pulp (CP) as a replacement for corn. Twenty-four newborn Holstein male calves were distributed into treatments according to starter composition: (1) 0% CP, (2) 32% CP, (3) 64% CP, on dry matter basis. The calves were housed in individual hutches, with free access to water and concentrate, and received 4 L/d of milk replacer. After diarrhea diagnosis, evaluations of fecal score, score of clinical signs and measurement of physiological parameters were performed three times a day during 3-d. Blood samples were collected for electrolytes, blood gases, and plasma biochemical analysis. Starter feed composition had no negative effect (P>0.05) on fecal score, characteristics of diarrheic stools and on the aggravation of diarrhea clinical signs. Biochemical, blood gases and electrolytes changes, as a function of starter composition, did not resulted (P>0.05) in dehydration, acidosis, or other metabolic disturbance animals. Total lactate and D-lactate plasma concentrations were higher for calves on control and 64% CP, and L-lactate was highest for the 64% CP; however, calves showed no signs of metabolic acidosis. Thermal comfort indexes influenced clinical and physiological parameters (P<0.05). Citrus pulp may replace corn in starter composition without prejudice to intestinal health or metabolism of young diarrheic calves.(AU)

O objetivo desse estudo foi o de avaliar os sinais clínicos, análise de gases e os efeitos metabólicos da diarreia em bezerros em aleitamento, consumindo concentrado inicial contendo polpa cítrica (PC) como substituto de milho. Vinte e quatro bezerros recém-nascidos da raça Holandesa foram distribuídos, de acordo com a composição do concentrado, nos seguintes tratamentos: (1) 0% PC, (2) 32% PC, (3) 64% PC, na matéria seca. Os bezerros foram alojados em abrigos individuais, com acesso livre a água e concentrado, e receberam 4L/d de sucedâneo lácteo. Após o diagnóstico de diarreia, avaliações de escore fecal, sinais clínicos e medidas de parâmetros fisiológicos foram realizadas três vezes ao dia durante 3-d. Amostras de sangue foram colhidas para análise de eletrólitos, hemogasometria e metabólitos plasmáticos. A composição do concentrado não afetou o escore fecal, as características das fezes diarreicas, ou o agravamento dos sinais clínicos da diarreia (P>0,05). Alterações nos parâmetros plasmáticos, de hemogasometria ou de eletrólitos, em função da composição do concentrado, não resultaram em desidratação, acidose ou outro distúrbio metabólico nos bezerros diarreicos (P>0,05). As concentrações de lactato total e D-lactato foram superiores para bezerros alimentados com concentrado sem inclusão de polpa ou com 64% de inclusão, enquanto a concentração de L-lactato foi superior somente para aqueles consumindo concentrado com 64% de PC. No entanto, os bezerros não apresentaram sinais de acidose metabólica. Os índices de conforto térmico influenciaram os parâmetros clínicos e fisiológicos (P<0,05). A polpa cítrica pode substituir o milho na composição de concentrados para bezerros sem prejudicar a saúde intestinal ou o metabolismo de bezerros jovens acometidos por diarreia.(AU)

Comportamento ingestivo e parâmetros sanguíneos em ovinos que receberam dietas contendo aditivos à base de extratos de própolis em pó / Ingestive behavior and blood profile in sheep fed with diets containing powdered propolis extract additives

Objetivou-se avaliar os efeitos do extrato de própolis (LLOSC2) sobre o comportamento ingestivo e os parâmetros sanguíneos em cordeiros alimentados com dieta concentrada. Foram utilizados quatro cordeiros machos, castrados, sem raça definida e com peso médio inicial de 32±1,92kg, mantidos em gaiolas metabólicas individuais durante todo o período experimental. O delineamento experimental foi em quadrado latino 4x4, com quatro animais, quatro dietas e quatro períodos experimentais. As dietas diferiram em relação à adição ou não de extratos de própolis à ração. As dietas testadas diferiam na adição de zero (controle), 1(88,16mg/g de flavonoides), duas (176,32mg/g de flavonoides) ou três (264,48mg/g de flavonoides) doses de aditivo à base de extrato de própolis LLOSC2. A dieta tinha relação volumoso:concentrado de 40:60 e foi formulada para ganhos de 250g. A ração concentrada era composta de milho e farelo de soja. O comportamento ingestivo dos animais foi observado por 24 horas, divididas em quatro períodos de seis horas. As coletas de sangue eram realizadas no último dia do período. Não houve efeito das doses LLOSC2 sobre o tempo despendido em alimentação, ruminação, ócio e ingestão de água. A duração do ciclo ruminativo foi maior nos animais que receberam duas doses de LLOSC2, e o número de movimentos mastigatórios também tendeu a aumentar no período que compreendia das 13 às 19h. Já a dieta contendo uma dose de LLOSC2 aumentou a duração da ruminação do bolo bem como o seu número total de mastigações no período de uma a sete horas. Houve uma diminuição nos níveis séricos de cortisol com a adição de três doses de LLOSC2. O hemograma, o leucograma, o perfil bioquímico e as imunoglobulinas não foram afetados pela inclusão das doses de LLSOC2. A administração de extrato de própolis LLOSC2 à dieta de ovinos não afetou seu comportamento ingestivo, os parâmetros hematológicos, bioquímicos e imunológicos estudados.(AU)

The objective of this study was to evaluate the effects of propolis extract (LLOS 2) on feeding behavior and blood parameters in lambs fed concentrate diet. Four male lambs were castrated, mongrel and average weight of 32±1.92kg, kept in individual metabolic cages throughout the trial period. The experimental design was a Latin square 4 x 4 with four animals, four treatments and four experimental periods. The diets differed according to addition or not of propolis extracts to feed. The experimental diets differed in addition to zero (control), 1 (88.16mg/g flavonoids) 2 (176.32mg/g flavonoids) or 3 (264.48mg/g flavonoids) Additive doses based on LLOSC2 propolis extract. The diet had a forage:concentrate ratio of 40:60 and was formulated to 250g gains. The concentrate ration was composed based on corn and soybean meal. The feeding behavior of the animals were observed for 24 hours, divided into four periods of 6 hours. Blood collections were made on the last day of the period. There was no effect of LLOSC2 doses on time spent eating, ruminating, leisure and water intake. The duration of the ruminative cycle was higher in animals that received two doses of LLOSC2 and the number of chewing movements also tended to increase in the period comprised from 13 to 19h. Since the diet containing a dose of LLOSC2, increased duration of rumination cake as well as its total number of chewing in the period of 1 to 7 hours. There was a decrease in serum cortisol with the addition of three doses of LLOSC2. The blood count, white blood cell count, biochemical profile and immunoglobulins were not affected by the inclusion of doses of LLSOC2. Administration of LLOSC2 propolis extract the sheep diet did not affect their feeding behavior, hematological, biochemical and immunological studies.(AU)

Parâmetros sanguíneos de frangos de corte alimentados com dietas suplementadas com sementes secas de Piper cubeba como aditivo fitogênico / Blood parameters of broiler chickens fed diets supplemented with dried seeds of Piper cubeba as an phytogenic additive

Dois experimentos foram realizados com o objetivo de avaliar o uso das sementes secas de Piper cubeba nas dietas de frangos de corte de 1 a 21 dias de idades e seus efeitos sobre o perfil bioquímicos do sangue e na biometria dos órgãos das aves. Em cada experimento 240 pintos de corte machos, com um dia de idade da linhagem Cobb foram distribuídos em um delineamento inteiramente casualizado, com cinco tratamentos e quatro repetições de 12 aves por parcela experimental. No primeiro experimento foi avaliado o uso da Piper cubeba em dietas consideradas de alta digestibilidade, a base de milho e farelo de soja, e no segundo avaliou-se o uso da pimenta em dietas de baixa digestibilidade, as quais foram obtidas com a inclusão de farinha de carne e ossos. Com relação aos dados de perfil bioquímico sanguíneo do experimento I, com exceção da gama glutamil transferase, todos os demais níveis séricos se apresentaram dentro dos limites recomendados para aves, e apenas os níveis de triglicerídeos diferiram entre os tratamentos (P<0,05). No experimento II houve diferença significativa para os níveis de albumina, colesterol e ácido úrico, porém isso não foi resultado de desordens metabólicas, visto que com exceção da gama glutamil transferase, todos os níveis encontraram-se dentro dos limites recomendados. Em ambos os experimentos não foram observadas diferenças (P>0,05) para a biometria dos órgãos. Nas condições em que os experimentos foram realizados a inclusão das sementes de Piper cubeba na ração para frangos de corte não proporcionou alterações bioquímicas e biométricas que possam limitar seu uso como material vegetal para os estudos fitogênicos.(AU)

Two experiments were conducted to evaluate the use of dried seeds of Piper cubeba in the diets of 1 to 21-day-old broilers and its effect on biochemical blood profile and biometry of the organs. In each experiment, 240 one-day-old male broiler chicks Cobb were distributed in a completely randomized design with five treatments and four replicates of 12 birds per experimental plot. The first experiment evaluated the use of Piper cubeba in considered highly digestible diets based on corn and soybean meal, and the second evaluated the use of pepper in low digestibility diets, which were obtained with the inclusion of meat and bone meal. Regarding the blood chemistry profile data of the experiment I, with the exception of gamma glutamyl transferase, all other serum levels were within recommended limits for poultry, and only triglyceride levels differed between treatments (P <0.05). In the second experiment there was significant difference in albumin levels, cholesterol and uric acid, but this was not the result of metabolic disorders, because except for the gama glutamyl transferase levels, all variables were within recommended levels. In both experiments, there were no differences (P> 0.05) for the biometry of organs. The conditions under which the experiments were performed at inclusion of Piper cubeba seeds in feed for broilers has not provided any toxicity to poultry.(AU)

Concentrações bioquímicas séricas de jacaré-açú (Melanosuchus niger) machos, adultos de vida livre / Biochemical serum concentrations of adult male caimans (Melanosuchus niger) in free life

O jacaré-açu (Melanosuchus niger), pertencendo à família Aligatoridae, é considerado o maior predador aquático da América Continental. Como todos os répteis, possui particularidades para o uso de energia, controlando sua temperatura corporal nas variações climáticas. Essas variações podem revelar a situação metabólica atual desse animal, justificando o estudo de tais parâmetros. A importância desse trabalho se justifica pela escassez de estudos disponíveis na literatura. Nesse sentido, determinamos o perfil bioquímico de compostos sanguíneos de 12 jacarés açu, com peso de 77,66±8,92 kg, os quais foram: uréia (3,41±0,66), albumina (24,85±0,63), proteína total (63,83±16,97), ácido úrico (0,25±0,09), glicose (6,99±0,77), colesterol total (2,20±0,27), triglicérides (0,58±0,07), TGO (138,83±9,16) e TGP (12,47±2,82).(AU)

The black caiman (Melanosuchus niger) of the Aligatoridae family is considered to be the largest aquatic predator of Continental America. Like all reptiles, the black caiman has special features for energy use to control his body temperature according to climatic variations. These variations can reveal the current metabolic status of the animals, explaining the importance to study such parameters. We determined the biochemical profile of some blood compounds of 12 alligators, weighing 77.66±8.92 kg, as there are: urea (3.41±0.66), albumin (24.85±0.63), total protein (63.83±16.97), uric acid (0.25±0.09), glucose (6.99±0.77), total cholesterol (2.20±0.27), triglycerides (0.58±0.07), TGO (138.83±9.16), and ALT (12.47±2.82).(AU)

Perfil hematológico e bioquímico de búfalos (Bubalus bubalis) na Amazônia Oriental / Hematologic and biochemical profile of buffaloes (Bubalus bubalis) in Eastern Amazonia

O hemograma e as dosagens bioquímicas são exames rotineiramente utilizados na avaliação da saúde dos animais domésticos, incluindo os búfalos. Na região Amazônica pesquisas nessa temática ainda são escassas. Desta forma, o objetivo deste trabalho foi estabelecer intervalos de referência para hematologia e bioquímica sanguínea de Bubalus bubalis criados na Amazônia Oriental e avaliar os efeitos da idade e do sexo sobre os valores bioquímicos e hematológicos obtidos. Foram utilizados 73 animais da raça Murrah, divididos em três grupos, o grupo 1 (G1, n=22) com animais de dois a oito meses, grupo 2 (G2, n=23) com animais de nove a dois anos e o grupo 3 (G3, n=28) com animais com mais de dois anos. Os hemogramas e as análises bioquímicas foram realizados em equipamentos automatizados. Os intervalos de referência foram estabelecidos conforme as recomendações do Clinical and Laboratory Standards Institute (CLSI). Para avaliar o efeito do sexo e da idade foram utilizados os testes de Tukey, e Kruskal-Wallis, sendo as diferenças consideradas significativas quando P<0,05. Houve influencia da idade sobre os valores de hemácias (He), hematócrito (Ht), hemoglobina (Hb), leucócitos, linfócitos, eosinófilos, neutrófilos, plaquetas, volume plaquetário médio (VPM), índices hematimétricos (Volume Globular Média - VGM, Hemoglobina Corpuscular Média - HCM, e Coeficiente de variação eritrocitário - RDW) e relação neutrófilo:linfócito (N:L). O sexo influenciou o valor do VGM e do índice de amplitude de distribuição do tamanho da plaqueta (PDW) que foram maiores (P<0,05) nas fêmeas, enquanto o RDW foi maior nos machos. Na comparação dos parâmetros bioquímicos entre as faixas etárias, verificou-se que a idade influenciou a atividade das enzimas aspartato aminotransferase (AST) e fosfatase alcalina (FA) e as concentrações de creatinina, proteínas totais e bilirrubina direta. As concentrações de creatinina e bilirrubina direta foram significativamente maiores nos animais da maior faixa etária. O sexo influenciou a atividade da AST e a concentração de bilirrubina direta, que foram maiores (P<0.05) nos machos. Os valores hematológicos e bioquímicos estabelecidos podem ser utilizados como referência para búfalos criados na Amazônia Oriental.(AU)

Complete blood cell count and biochemical testing are exams routinely used in assessing the health of domestic animals, including buffaloes. In the Amazon region, research on this subject is scarce. Thus, the aim of this study was to establish reference intervals for hematology and blood chemistry of Bubalus bubalis raised in eastern Amazon and evaluate the effects of age and sex on biochemical and hematological values. Seventy-three (n=73) Murrah buffaloes were divided into three groups, group 1 (G1, n=22): animals from two to eight months, group 2 (G2, n=23): animals from nine months to two years and group 3 (G3, n=28): animals over two years. Blood counts and biochemical analyzes were performed on automated equipment. The reference intervals were established as recommended by Clinical and Laboratory Standards Institute (CLSI). Tukey and Kruskal-Wallis tests were used to evaluate the effect of gender and age, with differences considered significant when P <0.05. There was influence of age on the values of red blood cells (RBC), packed cell volume (PCV), hemoglobin , leukocytes, lymphocytes, eosinophils, neutrophils, platelets, mean platelet volume (MPV), Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (HCM), Red Blood Cell Distribution Width (RDW) and the proportion of neutrophil: lymphocyte (N:L). The gender affected MCV and the Platelets Distribution Width (PDW), which were higher (P<0.05) in females, while RDW was higher in males. Comparing the biochemical parameters among age groups, it was found that age influenced the activity of the enzymes aspartate aminotransferase (AST) and alkaline phosphatase (ALP) and the concentrations of creatinine, total protein and direct bilirubin. Creatinine concentrations and direct bilirubin were significantly higher in animals of older age. The gender affected the activity of AST and the concentration of direct bilirubin, which were higher (P <0.05) in males. Hematological and biochemical values set in this study can be used as a reference for buffaloes bred in eastern Amazon.(AU)
