Effect of Moringa olifera leaves on growth and gut microbiota of Nile tilapia (Oreochromis niloticus) / Efeito das folhas da Moringa olifera no crescimento e na microbiota intestinal da tilápia do Nilo (Oreochromis niloticus)

Abstract The study was conducted to evaluate the effect of Moringa olifera on the growth and gut health of Tilapia (Oreochromis niloticus). The feed having 30% crude protein was prepared as an experimental diet with 4%, 8% and 10% M. olifera leaf supplementation, respectively. The control diet was devoid of M. olifera leaves. The 10 weeks feeding trial was carried out on 60 fish in aquaria. Fish was fed @ 3% of body weight twice a day. Diet with the high level of inclusion of M. olifera leaves significantly increased the growth rate, Survival Rate (SR), Specific Growth Rate (SGR) and Feed Conversion Efficiency (FCE) in all treatment groups compared to the control group. Similarly, Feed Conversion Ratio (FCR) gradually decreased and found highly-significant. To check the gut health of the Tilapia, random samples were selected and dissected. Nutrient agar was used as culture media to check the growth of bacteria. Pour Plate Method was used for viable colonies count by colony counter. Through staining method, the different bacteria such as Escherichia coli, Salmonella, Shigella and Pseudomonas aeruginosa were identify abundantly in the intestine of control diet fish but less number present in treatment diets groups. These results showed that M. olifera leaves up to 10% of dietary protein can be used for Nile tilapia for significant growth and healthy gut microbiota of fish.

A ração com 30% de proteína bruta foi preparada como dieta experimental com 4%, 8% e 10% de suplementação de folhas de M. olifera, respectivamente. A dieta controle foi desprovida de folhas de M. olifera. O ensaio de alimentação de 10 semanas foi realizado em 60 peixes em aquários. O peixe pesava 3% do peso corporal duas vezes ao dia. A dieta com alto nível de inclusão de folhas de M. olifera aumentou significativamente a taxa de crescimento, taxa de sobrevivência (SR), taxa de crescimento de sobrevivência (SGR) e eficiência de conversão alimentar (FCE) em todos os grupos de tratamento em comparação com o grupo de controle. Da mesma forma, a taxa de conversão de alimentação (FCR) diminuiu gradualmente e foi considerada altamente significativa. Para verificar a saúde intestinal da tilápia, amostras aleatórias foram selecionadas e dissecadas. O ágar nutriente foi usado como meio de cultura para verificar o crescimento das bactérias. O método da placa de Verter foi usado para a contagem de colônias viáveis ​​por contador de colônias. Através do método de coloração, diferentes como Escherichia coli, Salmonella, Shigella e Pseudomonas aeruginosa foram identificados abundantemente no intestino de peixes da dieta controle, mas em menor número nos grupos de dieta de tratamento. Esses resultados mostraram que M. olifera deixa até 10% da proteína dietética e pode ser usado para tilápia do Nilo para um crescimento significativo e microbiota intestinal saudável de peixes.

Limiting amino acids supplementation in low crude protein diets and their impacts on growth performance and carcass composition in Labeo rohita (rohu) adult fish / Limitação da suplementação de aminoácidos em dietas com baixo teor de proteína bruta e seus impactos no desempenho de crescimento e composição da carcaça em peixes adultos Labeo rohita (rohu)

Abstract Ninety days study was conducted in hapas installed in earthen ponds. Fish of an average initial weight (220g) were evenly distributed in triplicate groups within fifteen hapas. Five experimental diets labeled as T1 (25% CP and NRC recommended amino acid level) as control diet, T2 (with 2% low protein and 5% amino acid supplementation), T3 (with 2% low protein and 10% amino acid supplementation), T4 (with 4% low protein and 10% amino acid supplementation) and T5 (with 4% low protein and 20% amino acid supplementation) were prepared. Fish were fed with @3% of their body weight twice a day at 10.00 & 16:00 hour. Significantly higher percent weight gain (420.18 ± 66.84a) and specific growth rate (13499.33±1273.54a) along with improved feed conversion ratio (1.29 ± 0.09b) and hundred percent survivals were recorded during the trial. Furthermore proximate analysis of meat showed significant improvement in the crude protein level (81.77 ± 0.19a) served with diet containing 20% limiting amino acids mixture. Therefore, limiting amino acids can be a source of cost effective feed and use safely in L. rohita diet.

A comparative study on placebo and trenaxamic acid for the prophylaxis is of post-partum hemorrhage: a randomised double-blind control study

Background: Obstetric haemorrhage accounts for 20-25% of maternal mortality and morbidity. Anti-fibrinolytics are being widely used in field of surgery. It is also used to reduce heavy menstrual blood loss. The aim of this study was to analyse the effectiveness of TXA in reducing blood loss during normal vaginal delivery.Methods: The randomized double-blind control study was done in the Labour ward. It was conducted on 100 women undergoing Normal vaginal delivery. They were allocated to either Study or Control group by randomization. TXA was given during the Third stage of delivery in study group in addition to the routine care whereas the control group had routine care alone. Blood loss was measured in both groups by bag method.Results: The significant of reduction in blood loss calculated from placental delivery to 2hrs. 141.9 ml in study group versus 270.4 ml in control group. Among primi patients, the control group average blood loss was 325ml, the study group avg blood loss was 169ml. Among G2 patients, the control group average blood loss was 248.5ml. The study group average blood loss was 128.25ml. Among G3 patients, the control group average blood loss was 203ml, the study group average blood loss was 115ml.Conclusions: TXA significantly reduced the amount of blood loss during normal vaginal delivery. Thus, TXA can be used safely and effectively in subjects undergoing normal vaginal delivery.

Pharmacovigilance of corticosteroids in dermatological diseases

Background: The aim of the study was to conduct the monitoring, detection, assessment and prevention of corticosteroid induced adverse drug reactions in dermatological diseases.Methods: Patient demographic details, past medical, medication history, lab investigations, allergic history were collected patient were followed and data collected every 1 month from the day of patient recruitment. The 1st, 2nd and 3rd follow ups were done, analysis of ADRs was done by using scales at each follow-up. In statistical analysis, data was articulated in percentage. A prospective, interventional study were designed.Results: In present study, author have recruited 40 subjects of which authors categorized ADRs based on different systems. In that 14 (56%) ADRs were identified in cardiovascular system and it was the majorly affected organ system followed by endocrine system 4 (16%). In 40 patients, 25 patients developed ADRs. In these male patients was 14 (56%) and female patients was 11 (44%). In 25, the majorly developed ADR was hypertension 13 (52%) followed by DM 4 (16%). In all ADRs majorly developed due to use of Prednisolone 17 (42%). The developed ADRs majorly in the age group of 41-50 (48%) years followed by 31-40 (16%) and 51-60 (16%).Conclusions: The study found that incidence of ADRs in males was higher than that of the females. Prednisolone was the most common drug associated with the ADRs. Majority of reported ADRs were managed by giving suitable interventions and most of the patients recovered after management.

Respiratory syncytial virus infections in India: Epidemiology and need for vaccine

Respiratory syncytial virus (RSV) has been identified as a leading cause of lower respiratory tract infections in young children and elderly. It is an enveloped negative-sense RNA virus belonging to Genus Orthopneumovirus. The clinical features of RSV infection range from mild upper-respiratory-tract illnesses or otitis media to severe lower-respiratory-tract illnesses. Current estimates show that about 33.1 million episodes of RSV-acute lower respiratory infection (ALRI) occurred in young children in 2015, of these majority that is, about 30 million RSV-ALRI episodes occurred in low-middle-income countries. In India, the rates of RSV detection in various hospital- and community-based studies mostly done in children vary from 5% to 54% and from 8% to 15%, respectively. Globally, RSV epidemics start in the South moving to the North. In India, RSV mainly peaks in winter in North India and some correlation with low temperature has been observed. Different genotypes of Group A (GA2, GA5, NA1 and ON1) and Group B (GB2, SAB4 and BA) have been described from India. The burden of RSV globally has kept it a high priority for vaccine development. After nearly 50 years of attempts, there is still no licensed vaccine and challenges to obtain a safe and effective vaccine is still facing the scientific community. The data in this review have been extracted from PubMed using the keywords RSV and Epidemiology and India. The data have been synthesised by the authors.

Assessment of overweight, obesity and metabolic variables among students of a private medical college in Dhaka city.

Background: Overweight and obesity are recognized as recent threat which affecting both developing and developed countries. Obesity and its associated morbidities are leading cause of most non-communicable diseases. Few recent studies have indicated the presence of increase in overweight and obesity among children and adolescent but there is no study among adult groups. Method and material: This cross sectional study was done to assess the prevalence of overweight, obesity and metabolic variables with their relation among medical students. Result: Our result reveals that 8.6% & 1.9% male and 15% & 3.2% female are suffering from overweight and obesity (based on BMI) respectively. More females (31.3% and 65.2%) are centrally obese than males (3.5% and 34.8%) (According to Waist Hip ratio and Waist Height ratio respectively). But according to Waist circumference more males (30.7%) are obese than females (24%). There is also significant difference of male and female BP. DBP and SBP of male (79.22mmHg & 118.9 mmHg) have high normal level than female (72.71mmHg and 108.67mmHg) (P<0.001). There is no significant difference of glycaemic status (p<.286) and lipid profile (p<.347) with central obesity. Conclusion: Although male students have high upper level of blood pressure, female students are more obese than males (both according to BMI and central obesity). High blood pressure and obesity both acts as risk factors for the development of non communicable disease. Student’s awareness therefore should be increased to reduce central obesity and BP within normal range.

In vitro- In vivo Correlation Studies of Modified Release Tolterodine Tablet Dosage form in Rabbits.

Tolterodine is an antimuscarnic drug that is used for sympathetic treatment of urinary incontinence. Tolterodine modified release tablet, was investigated in rabbit for pharmacokinetic and in vitro–in vivo correlation studies. Tablets were prepared and in vitro release was studied in simulated gastric fluid at 150RPMs. New Zealand albino male rabbits have been used as animal model for in vivo study. A sensitive and simple HPLC method was developed for the determination of Tolterodine content in rabbit plasma. In vitro release studies showed that release patterns followed zero order for around 24h. The in vivo–in vitro correlation coefficients obtained from point-to-point analysis were greater than 99% between concentrations at certain time points obtained from release study in simulated gastric fluid and HPLC analysis of rabbit’s plasma. From the in vitro–in vivo correlation prediction it was evident that the Tolterodine matrix assisted tablet is a good for controlled delivery of Tolterodine.

Correlation and path coefficient analysis for yield and yield components in blackgram (vigna mungo (L.) hepper).

Correlation coefficient and path analysis studies was conducted with eight parents and their 28 F1 crosses for twelve component characters including seed yield and revealed significant positive association of pods per plant, harvest index and clusters per plant with seed yield in parental generation whereas in F1 generation, significant positive association of clusters per plant, pods per plant, days to maturity, days to 50% flowering, pods per cluster and 100-seed weight with seed yield was observed. Further, it was found that number of seeds per pod, harvest index, pods per plant and number of primary branches per plant showed high positive direct effects on seed yield in parents whereas in crosses, seeds per pod, pods per plant, harvest index and days to maturity showed high positive direct effect on seed yield. Hence selection based on these traits would be effective in increasing the seed yield.

Silicosis - A Case Report.

Silicosis is not an uncommon disease in Bangladesh as a good number of people are exposed to silica dust in their working places. Again pulmonary tuberculosis is also common here, the risk of which is increased by about 30 folds in silicosis. In the reported case, a young stone cutter of 40 years was admitted to Faridpur Medical College Hospital with progressive dyspnoea, dry cough and radiological appearance of multiple small and a large nodular pulmonary mass. Two of his brothers, also stonecutter, died of similar disease. In this context the patient was diagnosed as a case of chronic complicated silicosis and treated symptomatically as there is no curative treatment. A good number of people are engaged in stone cutting in our country including Faridpur district and are vulnerable to this progressive and non-curable disease. To aim of this case report is to make those people to be aware about the condition, so that they can protect themselves by taking appropriate measures (i.e. using protective mask) and should monitored their condition by regular chest x-ray. If early signs of silicosis is detected the worker should changed their job.

Effects of long term iodized table salt consumption on serum T3, T4 and TSH in an iodine deficient area of Bangladesh.

The effect of iodized and non-iodized table salt in goiter hyper-endemic area on the thyroid gland and its hormones T3, T4 and Thyroid Stimulating Hormone (TSH) were studied in two hundred subjects from the Center for Nuclear Medicine and Ultrasound, Mymensingh. Iodized and non-iodized salt users were called study and control groups respectively. The mean concentration of T3 were 2.38 nmol/L and 2.22 nmol/L & T4 concentration were 128.67 and 123.72 nmol/L in the study and control group respectively. The mean TSH concentration was 1.52 mIU/L and 1.62 mIU/L in study and control group. The data indicated that continuous and long term use of iodized salt increased both T3, T4 and decreased TSH in such a limit which was not statistically deferent at P< 0.05 level as compared to the control group. There was no significant change in occurrence of (hypo and hyper thyroidism or iodinated salt induced thyrotoxicosis) adverse effect, following iodine supplementation. The study shows that, mandatory mass iodination of table salt consumption in a hyper-endemic iodine deficient area is safe and does not cause any side effect. We suggest close regular monitoring of T3, T4, and TSH and further evaluation by specifically designed studies for any probable link between iodine induced hypo or hyperthyroidism and mass iodination of table salt consumption.

Serological response to immunization with tetanus toxoid.

A total of two hundred women were immunized with tetanus toxoid vaccine. Two batches of toxoid prepared at the Institute of Public Health (IPH), Dhaka and one batch of imported vaccines, were being used by the EPI in Bangladesh for immunization. Each hundred women were immunized by IPH and imported vaccine. Two human doses were given in one month interval. Blood samples from all the study subjects were collected on the day of 1st dose and one month after second dose. Both the preimmunized sera and the sera after vaccination were tested to determine the antibody titre against tetanus toxoid by the haemagglutination method. The preimmunized sera showed the presence of protective antibody in 50(25%) subjects who had the history of previous immunization. Including these initial antitoxin positive cases the seroconversions found among 95% and 96% of the study population respectively after immunization with IPH and imported toxoids, which were 93.05% and 94.87% when these 50 subjects were excluded. No significant difference (p = 1.0) was observed between the immunity of the subjects after receiving IPH and imported vaccine. Antibody titre of initial tetanus-antitoxin positive cases raised eight folds after getting more doses. The result gave fair indication of the antigenicity of all the toxoids used in the study.
