Evaluation of sulfadimidine, amprolium and triquen to treat coccidiosis in wild pigeons / Avaliação da sulfadimidina, amprólio e triquenho no tratamento da coccidiose em pombos selvagens de Lower Dir, Khyber Pakhtunkhwa, Paquistão

Coccidiosis remains one of the major problems in poultry all over the world. Very limited data on anticoccidial drugs in wild pigeons is available. The current study was aimed to understand the comparative efficacy of sulfadimidine, amprolium and triquen in wild pigeons of Dir district, Pakistan suffering from coccidiosis. The faecal matter of wild pigeons were purchased from the local market for coccidian infection. Results revealed that 88.8% (16/18) were found infected with Eimeria spp. Three positive groups were treated with sulfadimidine (0.2mg/L), amprolium (25mg/L) and triquen. Sulfadimidine was most effective (45%) followed by amprolium (44.6%) while triquen (24.0%) showed less effectiveness against coccidiosis in pigeons. Number of oocysts were 79, 81 and 80 before treatment and 60, 44 and 44 after treatment with sulfadimidine, amprolium and triquen respectively. This study showed that sulphadimidine, amprolium and triquen could not significantly reduce the coccidiosis in pigeons. Further studies are required to clear the mechanism of anti-coccidial drugs in wild pigeons.

O presente estudo teve como objetivo compreender a eficácia comparativa da sulfadimidina, amprólio e triquenho em pombos selvagens do distrito de Dir, no Paquistão, que sofrem de coccidiose. A matéria fecal dos pombos selvagens foi comprada no mercado local para infecção por coccídios. Os resultados revelaram que 88,8% (16/18) foram encontrados infectados com Eimeria spp. Três grupos positivos foram tratados com sulfadimidina (0,2mg / L), amprólio (25mg / L) e triquenho. A sulfadimidina foi mais eficaz (45%), seguida pelo amprólio (44,6%), enquanto o triquenho (24,0%) apresentou menor efetividade contra a coccidiose em pombos. O número de oocistos foram 79, 81 e 80 antes do tratamento e 60, 44 e 44 após o tratamento com sulfadimidina, amprólio e triquenho, respectivamente. Este estudo mostrou que sulphadimidine, amprolium e triquen não poderiam reduzir significativamente a coccidiose em pombos. Mais estudos são necessários para limpar o mecanismo de drogas anticoccidiais em pombos selvagens.

Assessment of ecto and endo parasites of Schizothorax plagiostomus inhabiting river Panjkora, Khyber Pakhtunkhwa, Pakistan / Avaliação de ecto e endoparasitas de Schizothorax plagiostomus habitantes do rio Panjkora, Khyber Pakhtunkhwa, Paquistão

Abstract Fish provides main source of high quality protein to more than one billion people in the world. Fish parasites directly affect the productivity of fish and indirectly on human health. This research was aimed to assess the helminth parasites in Schizothorax plagiostomus (the snow trout) from river Panjkora, KP, Pakistan. A total of 88 fish samples (n= 88) were collected from the upper, middle and lower regions of the river through cast nets, hand nets and hooks. All the collected fish samples were examined in the Parasitology Laboratory, Department of Zoology, University of Malakand for helminth parasites during July 2018 to February 2019.Among these fishes nematodes, trematodes, cestodes and acanthocephalan were isolated and identified. Overall prevalence of the fish parasites was 60.22% (53/88). The intensity of the parasite was observed from 1.7% to 4.61%. Highest prevalence was reported in summer season 86.36% while lowest in the winter season 36.36%. This study shows that summer season affects the fish business and result in poor quality fish meat with risk of zoonotic diseases. Adults were highly infected 82.25% while no infection was found in juvenile specimens. Female fish samples had higher prevalence 68.22% than males 48.22%. Fishes of the lower reaches had highest prevalence 60.22% than the upper reaches 40.0%. Fish samples with maximum length and weight were highly 76.92% infected than small sized fish with low body weight. Present study addresses that Rhabdochona schizothoracis in the intestine and Diplozoon paradoxum in gills of snow trout fish has a long term relationship and call as a natural infection in cyprinids and it is zoonotic threat to human.

Resumo O peixe é a principal fonte de proteína de alta qualidade para mais de um bilhão de pessoas no mundo. Contudo, parasitas afetam diretamente a produtividade de peixes e, indiretamente, a saúde humana. Esta pesquisa teve como objetivo avaliar os parasitas helmintos em Schizothorax plagiostomus (truta da neve) do rio Panjkora, Khyber Pakhtunkhwa, Paquistão. Foram coletadas 88 amostras de peixes (n = 88) dos trechos alto, médio e baixo do rio por meio de redes de arrasto, redes de mão e varas de pesca. Todas as amostras de peixes coletadas foram examinadas no Laboratório de Parasitologia do Departamento de Zoologia, da Universidade de Malakand, quanto a parasitas helmintos durante o período de julho de 2018 a fevereiro de 2019. Entre esses peixes, nematódeos, trematódeos, cestóideos e acantocéfalos foram isolados e identificados. A prevalência geral de parasitas de peixes foi de 60,22% (53/88). A intensidade do parasita foi observada de 1,7 a 4,61%. A maior prevalência (86,36%) foi relatada no verão, enquanto a menor (36,36%), no inverno. Este estudo mostra que a temporada de verão afeta o ramo da pesca e resulta em carne de baixa qualidade, com risco de doenças zoonóticas. Os adultos foram altamente infectados (82,25%), enquanto nenhuma infecção foi encontrada em jovens. As amostras de peixes do sexo feminino apresentaram maior prevalência (68,22%) do que as do sexo masculino (48,22%). Os peixes coletados no trecho baixo do rio tiveram maior prevalência (60,22%) do que os do trecho alto (40%). Amostras de peixes com comprimento e peso máximos foram altamente infectadas (76,92%) do que peixes de pequeno porte e baixo peso corporal. O presente estudo aborda que Rhabdochona schizothoracis no intestino e Diplozoon paradoxum em brânquias de peixes de truta da neve possuem uma estreita relação que causa uma infecção natural em ciprinídeos, sendo uma ameaça zoonótica ao ser humano.

Evaluation of ecto and endo parasitic fauna of Schizothorax plagiostomus inhabitants of river Swat, Khyber PakhtunKhwa, Pakistan / Avaliação da fauna ecto e endoparasitária de Schizothorax plagiostomus habitantes do rio Swat, Khyber Pakhtunkhwa, Paquistão

Abstract Fish is consumed as a rich and cheaper source of white meat and proteins all over the world. Fish farming is the leading source of income generation throughout the world. The present research study was conducted with aims to investigate the ecto and endo parasitic fauna of S. plagiostomus (snow trout) in River Swat. A total of 96 fish samples were collected on monthly basis from July-2018 to February-2019, from upper, middle and lower reaches. Fish samples were collected with the help of cast net, hand net and fishing rods. Local fishermen and experts help were also sought out for fish collection. 61 out of 96 fishes were found infected by helminth parasites. The total prevalence and intensity of 63.54% and 2.90 was observed respectively during data analysis. Highest monthly prevalence of 83.33% was recorded during July and August, while lowest prevalence of 33.33% was noted during February. Five species of helminths parasites were detected from S. plagiostomus, of which two were trematodes (Rhabdochona shizothoracis and Rhabdochona species), one species of Monogenia (Diplozoon paraddoxum), one species of Cestodes (Nippotaenia species), and one species of Acanthocephalan (Neoechynorhynchus devdevi). Highest parasite wise prevalence, intensity and relative density of 21.87%, 4.09 and 0.895 was noted for R. schizothoracis while the lowest prevalence, intensity and relative density of 4.16%, 1.25 and 0.052 was noted for N. devdevi. Highest infection of 76.08% was observed in adults host while lowest, 40% infestation rate was observed in young fish samples. 73.68% prevalence was observed in female hosts while only 56.90% prevalence was observed in male individuals. Higher infection (83.33%) was noticed during summer season, while lowest infection (44.44%) was observed during winter season. Similarly 71.79% fishes were found infected that were collected from lower reaches of the River Swat than the fish samples collected from upper reaches (52%).

Resumo O peixe é consumido mundialmente por ser uma fonte rica e barata de carne branca e proteínas. A piscicultura é a principal fonte de geração de renda em todo o mundo. O presente estudo foi conduzido com o objetivo de investigar a fauna ecto e endoparasitária de S. plagiostomus (truta da neve) no rio Swat. Foram coletadas mensalmente 96 amostras de peixes, no período de julho de 2018 a fevereiro de 2019, nos trechos alto, médio e baixo com auxílio de redes de arrasto, redes de mão e varas de pesca. Pescadores locais e especialistas também ajudaram na coleta de peixes. Dos 96 peixes encontrados, 61 estavam infectados por parasitas helmintos. A prevalência de 63,54% e a intensidade total de 2,90 foram observadas durante a análise dos dados. A maior prevalência mensal de 83,33% foi registrada nos meses de julho e agosto, enquanto a menor, de 33,33%, em fevereiro. Cinco espécies de parasitas helmintos foram detectadas de S. plagiostomus, dos quais dois eram trematódeos (espécies Rhabdochona shizothoracis e Rhabdochona), uma espécie de monogenia (Diplozoon paradoxum), uma espécie de cestóideos (espécie Nippotaenia) e uma espécie de acantocéfalo (Neoechynorhynchus devdevi). As maiores prevalências de parasitas (21,87%), intensidade (4,09) e densidade relativa (0,895) foram observadas em R. schizothoracis, enquanto as menores prevalências de parasitas (4,16%), intensidade (1,25) e densidade relativa (0,052), em N. devdevi. A infecção mais alta (76,08%) foi constatada em adultos hospedeiros, ao passo que a taxa de infestação mais baixa (40%) foi encontrada em amostras de peixes jovens. A prevalência de 73,68% foi verificada em hospedeiros do sexo feminino, enquanto a de 56,90%, em indivíduos do sexo masculino. Maior infecção (83,33%) foi observada durante a temporada de verão, e a menor infecção (44,44%), durante o inverno. Da mesma forma, 71,79% dos peixes encontrados infectados foram coletados no trecho baixo do rio Swat, enquanto 52%, no trecho alto.

The Newly Developed Highly Sensitive Method For The Determination Of Capecitabine By Using Uv-Spectroscopy

Capecitabine is a fluoropyrimidine carbamate, designed as 'pro-drug' to the cytotoxic agent 5-fluorouracil (5-FU) meant to be administered orally. Capecitabine is used as first line monotherapy for metastatic colorectal cancer. In the present study simple, rapid, accurate UV spectrophotometric methods were developed and validated for the estimation of capecitabine in bulk and its formulations as per ICH guidelines. Three solvent systems viz., 0.1N NaOH, 0.1N HCl and Methanol: Water (1:3) were tried. The results suggest that the developed methods shows linearity over the concentration range of 2-24μg/ml with a correlation coefficient of 0.9999. All the developed methods were statistically validated for accuracy, precision, linearity, robustness, and ruggedness as per ICH guidelines. The % RSD values for validated methods were found to be less than 1.5 and methods will find application in routine analysis of drug formulations containing capecitabine.

Highest prevalence was reported in summer season 86.36% while lowest in the winter season 36.36%. This study shows that summer season affects the fish business and result in poor quality fish meat with risk of zoonotic diseases. Adults were highly infected 82.25% while no infection was found in juvenile specimens. Female fish samples had higher prevalence 68.22% than males 48.22%. Fishes of the lower reaches had highest prevalence 60.22% than the upper reaches 40.0%. Fish samples with maximum length and weight were highly 76.92% infected than small sized fish with low body weight. Present study addresses that Rhabdochona schizothoracis in the intestine and Diplozoon paradoxum in gills of snow trout fish has a long term relationship and call as a natural infection in cyprinids and it is zoonotic threat to human.

Resumo O peixe é a principal fonte de proteína de alta qualidade para mais de um bilhão de pessoas no mundo. Contudo, parasitas afetam diretamente a produtividade de peixes e, indiretamente, a saúde humana. Esta pesquisa teve como objetivo avaliar os parasitas helmintos em Schizothorax plagiostomus (truta da neve) do rio Panjkora, Khyber Pakhtunkhwa, Paquistão. Foram coletadas 88 amostras de peixes (n = 88) dos trechos alto, médio e baixo do rio por meio de redes de arrasto, redes de mão e varas de pesca. Todas as amostras de peixes coletadas foram examinadas no Laboratório de Parasitologia do Departamento de Zoologia, da Universidade de Malakand, quanto a parasitas helmintos durante o período de julho de 2018 a fevereiro de 2019. Entre esses peixes, nematódeos, trematódeos, cestóideos e acantocéfalos foram isolados e identificados. A prevalência geral de parasitas de peixes foi de 60,22% (53/88). A intensidade do parasita foi observada de 1,7 a 4,61%. A maior prevalência (86,36%) foi relatada no verão, enquanto a menor (36,36%), no inverno. Este estudo mostra que a temporada de verão afeta o ramo da pesca e resulta em carne de baixa qualidade, com risco de doenças zoonóticas. Os adultos foram altamente infectados (82,25%), enquanto nenhuma infecção foi encontrada em jovens. As amostras de peixes do sexo feminino apresentaram maior prevalência (68,22%) do que as do sexo masculino (48,22%). Os peixes coletados no trecho baixo do rio tiveram maior prevalência (60,22%) do que os do trecho alto (40%). Amostras de peixes com comprimento e peso máximos foram altamente infectadas (76,92%) do que peixes de pequeno porte e baixo peso corporal. O presente estudo aborda que Rhabdochona schizothoracis no intestino e Diplozoon paradoxum em brânquias de peixes de truta da neve possuem uma estreita relação que causa uma infecção natural em ciprinídeos, sendo uma ameaça zoonótica ao ser humano.

Evaluation of ecto and endo parasitic fauna of Schizothorax plagiostomus inhabitants of river Swat, Khyber PakhtunKhwa, Pakistan

Abstract Fish is consumed as a rich and cheaper source of white meat and proteins all over the world. Fish farming is the leading source of income generation throughout the world. The present research study was conducted with aims to investigate the ecto and endo parasitic fauna of S. plagiostomus (snow trout) in River Swat. A total of 96 fish samples were collected on monthly basis from July-2018 to February-2019, from upper, middle and lower reaches. Fish samples were collected with the help of cast net, hand net and fishing rods. Local fishermen and experts help were also sought out for fish collection. 61 out of 96 fishes were found infected by helminth parasites. The total prevalence and intensity of 63.54% and 2.90 was observed respectively during data analysis. Highest monthly prevalence of 83.33% was recorded during July and August, while lowest prevalence of 33.33% was noted during February. Five species of helminths parasites were detected from S. plagiostomus, of which two were trematodes (Rhabdochona shizothoracis and Rhabdochona species), one species of Monogenia (Diplozoon paraddoxum), one species of Cestodes (Nippotaenia species), and one species of Acanthocephalan (Neoechynorhynchus devdevi). Highest parasite wise prevalence, intensity and relative density of 21.87%, 4.09 and 0.895 was noted for R. schizothoracis while the lowest prevalence, intensity and relative density of 4.16%, 1.25 and 0.052 was noted for N. devdevi. Highest infection of 76.08% was observed in adults host while lowest, 40% infestation rate was observed in young fish samples. 73.68% prevalence was observed in female hosts while only 56.90% prevalence was observed in male individuals. Higher infection (83.33%) was noticed during summer season, while lowest infection (44.44%) was observed during winter season. Similarly 71.79% fishes were found infected that were collected from lower reaches of the River Swat than the fish samples collected from upper reaches (52%).

Resumo O peixe é consumido mundialmente por ser uma fonte rica e barata de carne branca e proteínas. A piscicultura é a principal fonte de geração de renda em todo o mundo. O presente estudo foi conduzido com o objetivo de investigar a fauna ecto e endoparasitária de S. plagiostomus (truta da neve) no rio Swat. Foram coletadas mensalmente 96 amostras de peixes, no período de julho de 2018 a fevereiro de 2019, nos trechos alto, médio e baixo com auxílio de redes de arrasto, redes de mão e varas de pesca. Pescadores locais e especialistas também ajudaram na coleta de peixes. Dos 96 peixes encontrados, 61 estavam infectados por parasitas helmintos. A prevalência de 63,54% e a intensidade total de 2,90 foram observadas durante a análise dos dados. A maior prevalência mensal de 83,33% foi registrada nos meses de julho e agosto, enquanto a menor, de 33,33%, em fevereiro. Cinco espécies de parasitas helmintos foram detectadas de S. plagiostomus, dos quais dois eram trematódeos (espécies Rhabdochona shizothoracis e Rhabdochona), uma espécie de monogenia (Diplozoon paradoxum), uma espécie de cestóideos (espécie Nippotaenia) e uma espécie de acantocéfalo (Neoechynorhynchus devdevi). As maiores prevalências de parasitas (21,87%), intensidade (4,09) e densidade relativa (0,895) foram observadas em R. schizothoracis, enquanto as menores prevalências de parasitas (4,16%), intensidade (1,25) e densidade relativa (0,052), em N. devdevi. A infecção mais alta (76,08%) foi constatada em adultos hospedeiros, ao passo que a taxa de infestação mais baixa (40%) foi encontrada em amostras de peixes jovens. A prevalência de 73,68% foi verificada em hospedeiros do sexo feminino, enquanto a de 56,90%, em indivíduos do sexo masculino. Maior infecção (83,33%) foi observada durante a temporada de verão, e a menor infecção (44,44%), durante o inverno. Da mesma forma, 71,79% dos peixes encontrados infectados foram coletados no trecho baixo do rio Swat, enquanto 52%, no trecho alto.

Nickel, its adverse health effects & oxidative stress.

Nickel-induced toxicity and carcinogenicity, with an emphasis on the generation and role of reactive oxygen species is reviewed. Nickel is a known haematotoxic, immunotoxic, neurotoxic, genotoxic, reproductive toxic, pulmonary toxic, nephrotoxic , hepatotoxic and carcinogenic agent. This article presents a selective review on nickel and effect of its acute, subchronic and chronic doses on certain metabolically active tissues in human as well as animals. Nickel exposure causes formation of free radicals in various tissues in both human and animals which lead to various modifications to DNA bases, enhanced lipid peroxidation, and altered calcium and sulphydryl homeostasis. The primary route for nickel toxicity is depletion of glutathione and bonding to sulphydryl groups of proteins. Nickel homeostasis, nickel-induced activation of signaling pathways and the protective role of enzymatic and non-enzymatic antioxidants against nickel toxicity and carcinogenicity are also discussed.

Malarial hepatitis as a component of multiorgan failure--a bad prognostic sign.

A prospective study among the patients (n = 301) belonging to the coastal districts of Orissa having complicated falciparum malaria with multiorgan failure fulfilling modified APACHE II criteria, for a period of two years in this hospital setting was carried out with particular emphasis on hepatic involvement. There were 206 males and the rest females. Hepatic involvement in the form of raised serum bilirubin levels > or = 6 mg% and prothombin time > 4 compared to controls was found in 192 cases (63.8%). On analysis out of 192 cases predominantly conjugated hyperbilirubinaemia, mixed patterns and unconjugated hyperbilirubinaemia were seen in 115 (59.9%), 64 (33.3%) and 13 (6.8%) cases respectively. Serum bilirubin ranged from 6 to 38 mg%. Aminotransferase aspartate (AST, SGOT) and aminotransferase alkaline (ALT, SGPT) were raised almost two-fold in 98% cases of multiorgan failure with hepatic failure with mean values of 78 +/- 30.4 IU/l and 81 +/- 29.06 IU/l respectively. Nearly three-fold elevation of alkaline phosphatase was observed in 80% cases with mean (315 +/- 39.4 IU/l). Prothombin time was prolonged with mean 7 +/- 3 seconds. Serum proteins and albumin/globulin ratio were normal. There was no difference in glycaemic status over controls. In selected cases, liver histopathological study showed abnormalities in the form of Kupffer cell hyperplasia, mononuclear cell infiltration, hepatocyte necrosis, fatty changes and cholestasis. Majority of patients in multiorgan failure who died, had hepatic failure.

Cases referred for tests of thyroid function disorders at a tertiary care teaching hospital of Bihar: some experience.

In the absence of valid hospital protocol for clinical departments of M.G.M. Medical College and L.S.K.Hospital, Kishanganj, as many as, 76.78% of patients was referred to biochemistry laboratory, in which disease was not present. Of 196 diseased (23.22% of total), male and female was respectively 44 and 152. There was no significant sex difference in positivity among patients referred for investigation. Hypothyroid was major diagnosis, yet hyperthyroid was noticeable.

Placebo controlled trial of methotrexate in systemic sclerosis.

Eighteen adult patients of systemic sclerosis were included in this prospective study from Rheumatology Clinic of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during the period of July 1997 to December 1999 to observe the effectiveness of treatment with methotrexate (MTX) versus placebo. Among the eighteen patients 9 patients were randomly assigned to MTX and 9 to placebo therapy. Nine patients were dropped out (6 in placebo and 3 in the MTX group), because of toxicity and non-compliance. Clinical improvement following treatment was observed in 33.33% of the patient in MTX group but none in placebo group, but this difference was not statistically significant. Anorexia, nausea and occasional vomiting were common side effects in MTX group and subsided in most cases with the passage of time despite the continuation of therapy.

Congenital granular cell lesion "congenital epulis"--report of a case.

Congenital granular cell lesion (CGCL) or "congenital epulis" is a rare lesion of newborn also known as Neuman's Tumor, which is benign in nature, mostly occurs as a single tumour but rarely as multiple. The histogenesis and natural clinical history of the lesion remains obscure. Even with the advent of modem histopathological techniques, it has not been possible to depict specific cellular features unique to this lesion. This lesion arises from mucosa of gingiva either from maxillary or mandibular alveolar ridge. The appearance of the lesion is most common in maxillary alveolar ridge than mandibular with predominance in females than in the males. The present report describes a case of congenital granular cell lesion (CGCL) in the incisor region of mandibular alveolar ridge. This lesion was causing feeding problem and was excised under local anaesthesia.

Management of dengue by the WHO guided national guidelines.

A total of 90 adult patients of Dengue admitted in Sir Salimullah Medical College and Mitford Hospital, Dhaka during the period from July 2002 to December 2002 were studied to see the presentation, spectrum of disease and outcome of management. Majority (52%) of cases was in the age group 21-30 years. Out of 90 patients 74 patients (82.22%) were male and 16 (17.78%) were female. Maximum number of cases (43%) was found in the month of August. Most of the cases (77%) were from Dhaka City. Classical type of Dengue fever was the commonest (80%) variety. Thrombocytopenia was found in 80% cases. Platelet count came down below 10000/cumm only in 1.1% of the patients. The patients were diagnosed mainly by clinical criteria. Serological tests were done only in selected cases. Majority (80%) of the patients was managed by sponging, paracetamol and Oral Rehydration Salt (ORS). Blood transfusion was required in 18% cases and platelet concentrate was given only in 1.1% cases. There was no mortality in this study.
