This study aims at reporting the indigenous knowledge of the medicinal flora from the inhabitants of surroundings of the World's largest artificial planted forest "Changa Manga", Pakistan. Data were collected by direct interviews and group meetings from 81 inhabitants including 32 local healers having information regarding the use of indigenous medicinal plants over a period of one year. Different statistical tools were applied to analyze the data including Frequency citation (FC), Relative frequency citation (RFC), Use Value, Factor of informants consensus and fidelity level. This study reported 73 plant species belonging to 37 plant families and 46 genera. The majority of plant species belong to compositae family. The most commonly used medicinal plants were P. hysterophorus L., P. dactylifera L., S. indicum L, P. harmala L., P. emblica L., and A. indica A.Juss. The greatest number of species was used to cure gastrointestinal disorders. The highest fidelity level (68.18%) was of E. helioscopia to cure gastrointestinal disorders. Maximum fresh uses (17) were reported by C. dactylon (L.) Pars. While the highest number of species reporting fresh uses in similar number was 13. In this study, five novel plants are being reported for the first time in Pakistan for their ethnomedicinal worth. Our data reflect unique usage of the medicinal plants in the study area. The statistical tools used in the study proved useful in pointing the most important and disease category specific plants. High use value plant and the new reported medicinal plants might prove an important source of the isolation of pharmacologically active compounds.

Abstract Fishmeal; being a limited and costly feed ingredient is continuously been substituted with locally available plant proteins. However, the occurrence of anti-nutritional factors in plant meal suppresses its potential to be fully replaced. Therefore, in this study we aimed to study the synergistic effects of dietary additives like citric acid and phytase enzyme supplementation on growth performance and nutrient digestibility of Cirrhinus mrigala fingerlings. Canola meal (CM) was used as a test ingredient to replace fishmeal (FM) as; 0%, 25%, 50% and 75%. These four diets were further supplemented by varying levels of phytase (0 and 750 FTU kg-1) and citric acid (0% and 2.5%) to formulate total sixteen test diets as T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15 and T16. Each treatment contained three replicates; applied to fish groups having 15 fingerlings each; following 3×3 factorial arrangement. 1% of chromic oxide was added as an inert marker. Maximum weight gain% (288%) and the lowest value of FCR (1.07) were recorded when fish was fed on diet T12 as compared to fish fed control diet (T1). Similarly, optimum nutrient digestibility values such as crude protein (77%), crude fat (84%) and gross energy (70%) were noted on same level. It was concluded that 50% canola meal can optimally replace fishmeal when supplemented with phytase and citric acid at the levels of 750 FTU kg-1 and 2.5%, respectively.
Resumo A farinha de peixe, por ser um ingrediente alimentar limitado e caro, é continuamente substituída por proteínas vegetais disponíveis localmente. No entanto, a ocorrência de fatores antinutricionais na farinha de plantas suprime seu potencial de ser totalmente substituída. Portanto, neste estudo objetivamos estudar os efeitos sinérgicos de aditivos dietéticos como ácido cítrico e suplementação com enzima fitase sobre o desempenho de crescimento e digestibilidade de nutrientes de alevinos de Cirrhinus mrigala. A farinha de canola (CM) foi usada como ingrediente de teste para substituir a farinha de peixe (FM) como: 0%, 25%, 50% e 75%. Essas quatro dietas foram suplementadas por níveis variados de fitase (0 e 750 FTU kg-1) e ácido cítrico (0% e 2,5%) para formular um total de 16 dietas de teste como T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15 e T16. Cada tratamento continha três repetições; aplicado a grupos de peixes com 15 alevinos cada; seguindo o arranjo fatorial 3 × 3. 1% de óxido crômico foi adicionado como um marcador inerte. % de ganho de peso máximo (288%) e o valor mais baixo de FCR (1,07) foram registrados quando os peixes foram alimentados com dieta T12 em comparação com peixes alimentados com dieta controle (T1). Da mesma forma, valores ótimos de digestibilidade de nutrientes, como proteína bruta (77%), gordura bruta (84%) e energia bruta (70%) foram anotados no mesmo nível. Concluiu-se que 50% da farinha de canola pode substituir de forma ideal a farinha de peixe quando suplementada com fitase e ácido cítrico nos níveis de 750 FTU kg-1 e 2,5%, respectivamente.

The growth of aquaculture sector is strongly dependent upon the continuous supply of inexpensive fish feed with balanced nutritional profile. However, fish meal (FM) is unable to satisfy this demand due to its scarce supply and high cost. In order to test the potential of cottonseed meal (CSM) as a fish meal replacer, a feeding trial of 12 weeks was conducted to check growth performance and proximate composition of Labeo rohita fingerlings. The protein ration of the test feed was satisfied by replacing FM with CSM at 0, 25, 50 and 75%. Sixteen test diets viz., TD1 (control), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 and TD16 were supplemented with citric acid (CA; 0 and 2.5%) and phytase (PHY; 0 and 750 FTU/kg) in a completely randomized design with 3×3 factorial arrangement. The highest weight gain (11.03g), weight gain% (249.21%), specific growth rate (1.39) and best feed conversion ratio (1.20) were recorded by fish fed with TD12. Furthermore, the same level increased the crude protein (59.26%) and fat (16.04%) being significantly different (p<0.05) than that of control. Conclusively, the addition of acidified phytase (CA; 2.5%, PHY; 750 FTU/kg) in TD12 (CSM=50%) led to the improved growth and proximate composition of L. rohita fingerlings.

Porém, a farinha de peixe (FM) não consegue atender a essa demanda devido à sua escassa oferta e alto custo. Com o objetivo de testar o potencial da farinha de semente de canola (MSC) como substituto da farinha de peixe, um ensaio alimentar de 12 semanas foi conduzido para verificar o desempenho de crescimento e a composição centesimal de alevinos de Labeo rohita. A ração de proteína da ração teste foi satisfeita substituindo FM por CSM em 0, 25, 50 e 75%. Dezesseis dietas de teste, viz., TD1 (controle), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 e TD16 foram suplementadas com ácido cítrico (CA; 0 e 2,5%) e fitase (PHY; 0 e 750 FTU / kg) em um delineamento inteiramente casualizado com arranjo fatorial 3 × 3. O maior ganho de peso (11,03g), % de ganho de peso (249,21%), taxa de crescimento específico (1,39) e melhor taxa de conversão alimentar (1,20) foram registrados por peixes alimentados com TD12. Além disso, o mesmo nível aumentou a proteína bruta (59,26%) e a gordura (16,04%), sendo significativamente diferente (p <0,05) do controle. Conclusivamente, a adição de fitase acidificada (CA; 2,5%, PHY; 750 FTU / kg) em TD12 (CSM = 50%) levou a um melhor crescimento e composição próxima de alevinos de L. rohita.

Fish protein is serving as a source of nutrition for protein starving world. However, sustainable aquaculture products require inexpensive plant by-products due to finite sources of fish meal. Therefore, this study was conducted to examine nutrient utilization, growth performance and hematological indices of Cirrhinus mrigala fingerlings fed on Moringa oleifera leaf meal (MOLM) based diets. Fish were fed with six isonitrogenous and isoenergetic diets having MOLM as a substitute of fish meal (FM) at the levels of 0%, 10%, 20%, 30%, 40% and 50% for the period of 90 days. Fingerlings having initial weight 6.35±0.04g were reared in triplicate tanks at the stocking density of 15 and hand fed at the rate of 5% of total biomass twice regularly. Chromic oxide inclusion level was 1% in diets. After analysis, maximum growth performance and improved digestibility of nutrients were found in fish fed with diet at 10% replacement level as compared to fish fed on control diet and other test diets. Additionally, it was found that the red blood cells, white blood cells, hemoglobin and mean corpuscular hemoglobin concentration of fish showed a significantly (p<0.05) inverse correlation with the increase in MOLM. In present research, it was concluded that MOLM has good potential to be used as a FM substitute in C. mrigala diet with maximum effect at 10% showing positive hematological indices.
A proteína do peixe está servindo como fonte de nutrição para o mundo faminto por proteína. No entanto, produtos de aquicultura sustentáveis requerem subprodutos vegetais baratos devido às fontes finitas de farinha de peixe. Portanto, este estudo foi conduzido para examinar a utilização de nutrientes, o desempenho do crescimento e os índices hematológicos de alevinos de Cirrhinus mrigala alimentados com dietas à base de farelo de folhas de Moringa oleifera (MOLM). Os peixes foram alimentados com seis dietas isonitrogênicas e isoenergéticas contendo MOLM como substituto da farinha de peixe (FM) nos níveis de 0%, 10%, 20%, 30%, 40% e 50% pelo período de 90 dias. Os alevinos com peso inicial de 6,35 ± 0,04g foram criados em tanques triplicados com densidade de 15 animais e alimentados à mão a uma taxa de 5% da biomassa total duas vezes regularmente. O nível de inclusão de óxido crômico foi de 1% nas dietas. Após análise, desempenho máximo de crescimento e melhor digestibilidade de nutrientes foram encontrados em peixes alimentados com dieta em nível de reposição de 10% em comparação com peixes alimentados com dieta controle e outras dietas teste. Além disso, verificou-se que as concentrações de hemácias, leucócitos, hemoglobina e hemoglobina corpuscular média dos peixes apresentaram correlação inversa significativa (p < 0,05) com o aumento do MOLM. Na presente pesquisa, concluiu-se que o MOLM tem bom potencial para ser utilizado como substituto do FM na dieta de C. mrigala com efeito máximo a 10% apresentando índices hematológicos positivos.

Two major hospitals in Kano, North West Nigeria have recorded increasing resistance of clinical pathogens to broad spectrum β lactams, mediated by extended spectrum β- lactamase (ESβL) and non ESBLs. A study was therefore undertaken to determine the occurrence and prevalence of plasmid and chromosomal mediated AmpC βL and carbapenemase in addition to already known ESBL due to increasing resistance of pathogens from the two hospitals to carbapenems, cephamycins and flouroquinolones. Antibiogram tests and ESBL, AmpC and carbapenemase production tests were performed on all the isolates. AmpC and carbapenemase producers were further screened for AmpC inducibility and metallo beta lactamase production respectively. Majority of the isolates (> 80%) were resistant to both β-lactam and non β-lactam antibiotics. Reduced susceptibility to levofloxacin, nitrofurantoin, nalidixic acid and ofloxacin among the isolates were observed with the exception of P. aeruginosa which is totally resistant to imipenem and levofloxacin. An overall prevalence of 14.4%, 11.9% and 11.9.3% for ESβL, AmpC and carbapenemase was observed respectively. About 7.9% of the AmpC producers can over expressed the chromosomally mediated AmpC and 85.8% of the carbapenemase producers require metal for their action. Co-production of either of two and/or all of the enzymes was observed in E. coli, P. mirabilis and P. aeruginosa. Antibiotic resistance among isolates from the two hospitals is increasing and the major cause of this resistance in the pathogens studied are production of AmpC, carbapenemase (especially Metallo β- lactamase) in addition to already known ESBL enzymes by the pathogens. Some of the isolates also possess the capacity to elaborate two or more of the enzymes concurrently, which would renders them resistant to a multitude of antibiotics.

Treatment of metastatic neck gland is an integral part of management of Head and Neck cancers, because this is the single most important prognostic determining factor. Although surgery and radio therapy with or without chemotherapy are the modalities available for treating neck gland, wide surgical excision of the whole regional lymphatic chain enblock is mostly favored. Radical Neck dissection is the operation for such disease, designed in the early part of twentieth century, still has got the validity, but a modification of that (modified radical neck dissection) is becoming popular for last few decades to reduce morbidity. In this study we compared 15 cases of radical neck dissection and equal number of modified radical neck dissection to observe the selection criteria of these two types of operations, their complications and therapeutic success. Neck deformity, shoulder pain and restricted shoulder movement are the major morbidities which are less in modified radical neck dissection. The oncologic efficacy appears as same in both procedures.

Penetrating injury in the neck is not an uncommon condition, but a perforating foreign body like bamboo in the neck is uncommon. A 36 years old young man was admitted in Otolaryngology and Head Neck surgery department, Mymensingh Medical College hospital, with a history of accidental perforating injury in the neck with a bamboo, while driving a vehicle (tempo). Clinical examination revealed a bamboo measuring 4.6 X 0.09 ft. perforated in his neck from left to right. Surprisingly great vessels and air way spared. Due to difficult intubation, elective tracheostomy was done. Neck was explored and foreign body removed under general anesthesia. Haemostasis ensured and wound closed in layers after putting drain tubes. Recovery was uneventful and was discharged after three weeks.
