Histopathological alterations in gills, liver, kidney and muscles of Ictalurus punctatus collected from pollutes areas of River / Alterações histopatológicas em brânquias, fígado, rim e músculos de Ictalurus punctatus coletados em áreas poluídas do rio

Abstract Untreated sewage and industrial wastes from Faisalabad city are disposed to River Chenab through Chakbandi Main Drain (CMD). The present project is planned to investigate the effects of this freshwater pollution on the body of fish Ictalurus punctatus. The specimens of this fish species were collected upstream and downstream of the entrance of CMD into River Chenab. Fish gills, liver, kidney and muscles from dorsolateral regions of fish were subjected to histopathology. Farmed fish and fish from upstream areas were used as control. Fish collected from polluted experimental sites showed significant damage in selected organs. Gill tissues showed an abnormality in the form of an uplifting of the primary epithelium, fusion, vacuolation, hypertrophy, and necrosis. While liver tissues subjected to hepatocytes degeneration, necrosis, mitochondrial granular hepatocyte, and sinusoids dilation. Kidney tissues indicated increased bowmen space and constricted glomerulus and degenerated nephrons. Edema, necrosis, and atrophy were observed in muscle tissues of fish from polluted areas. Fish from the upstream area showed fused gill lamellae, inflammatory cell infiltration, hypertrophy and vacuolation in hepatocytes. Kidney tissues indicated the presence of nuclear tubular cells, destructive renal tubules, hemorrhage, and necrosis at tubular epithelium. Intra myofibril spaces were also observed in muscles. Specimens of control fish indicated no variation in gills, liver, kidney, and muscles. The present study revealed a strong correlation between the degree of tissue damage and environmental contamination. Present findings also compel global warnings to protect our water bodies and fish to rescue the human population.

Resumo O esgoto não tratado e os resíduos industriais da cidade de Faisalabad, no Paquistão, são descartados no Rio Chenab através do dreno principal de Chakbandi (CMD). O presente projeto busca investigar os efeitos dessa poluição de água doce no corpo de peixes Ictalurus punctatus. Os espécimes deste peixe foram coletados a montante e a jusante da entrada do CMD no Rio Chenab. Brânquias, fígado, rim e músculos das regiões dorsolaterais dos peixes foram submetidos à histopatologia. Peixes de criação e peixes de áreas a montante foram utilizados como controle. Peixes coletados em locais experimentais poluídos mostraram danos significativos em órgãos selecionados. Os tecidos branquiais mostraram uma anormalidade na forma de elevação do epitélio primário, fusão, vacuolação, hipertrofia e necrose. Observou-se que os tecidos hepáticos estão sujeitos a degeneração de hepatócitos, necrose, hepatócitos mitocondriais granulares e dilatação de sinusoides. Os tecidos renais indicaram aumento do espaço dos arqueiros, glomérulos contraídos e néfrons degenerados. Edema, necrose e atrofia foram observados nos tecidos musculares de peixes de áreas poluídas. Peixes da área a montante apresentaram lamelas branquiais fundidas, infiltração de células inflamatórias, hipertrofia e vacuolização em hepatócitos. Os tecidos renais indicaram a presença de células tubulares nucleares, túbulos renais destrutivos, hemorragia e necrose no epitélio tubular. Os espaços intramiofibrilas também foram observados nos músculos. Amostras de peixes controle não indicaram variação em brânquias, fígado, rim e músculos. O presente estudo revelou uma forte correlação entre o grau de dano tecidual e a contaminação ambiental. As descobertas atuais também constituem avisos globais para proteger nossos corpos d'água e peixes para resguardar a população humana.

Potential of natural repellents methylanthranilate and anthraquinone applied on maize seeds and seedlings against house sparrow (Passer domesticus) in captivity / Potencial de repelentes naturais, metilantranilato e antraquinona aplicados em sementes de milho e mudas contra o pardal (Passer domesticus) em cativeiro

Abstract Various bird pests caused severe economic losses to valuable crops and fruit orchards all over the world. Among the birds, house sparrow is also considered to cause heavy plunder, not only to seeds of crops but also seedlings especially in organic farming. In present study two bird repellents, methylanthranilate and anthraquinone tested against house sparrows on maize seeds and seedlings in aviary conditions. Trial group in aviary-I, the treated maize seeds and seedlings with different doses of both bird repellents, control group in aviary-II, untreated seeds and seedlings were provided for three hours in the early morning. In each aviary, two closed circuit cameras were also installed to monitor the behavioral responses against different concentrations of both chemical repellents. Statistical analysis showed that there existed highly significant (P<0.01) variations among the trial and control groups for seeds and seedlings. By comparing both repellents, significant (P<0.05) differences were detected and anthraquinone showed better efficacy when compared to methylanthranilate, but in maize seedlings both repellents equal repellent properties. Non-significant (P>0.05) differences were observed in different grading of both natural chemical repellents for maize seeds while significant (P<0.05) variations were noticed for maize seedlings when provided to sparrows. By videotaped behavior sparrows presented manifest head juddering and feather upsetting activities by consumption of treated seeds and seedlings with higher concentrations of both natural bird repellents.

Resumo Várias pragas de aves causaram graves perdas econômicas para cultivos valiosos e pomares de frutas em todo o mundo. Entre os pássaros, o pardal da casa também é considerado um grande saqueo, não só para as sementes das culturas, mas também para as mudas, especialmente na agricultura orgânica. No presente estudo, dois repelentes de aves, metilantranilato e antraquinona testados contra pardais de casa em sementes de milho e mudas em condições de aviário. O grupo de ensaio em aviary-I, as sementes de milho tratadas e as mudas com diferentes doses de repelentes de aves, grupo de controle em aviary-II, sementes não tratadas e mudas foram fornecidas por três horas no início da manhã. Em cada aviário, duas câmeras de circuito fechado também foram instaladas para monitorar as respostas comportamentais contra diferentes concentrações de ambos os repelentes químicos. A análise estatística mostrou que existiam variações altamente significativas (P<0,01) entre os grupos de teste e controle para sementes e mudas. Ao comparar os dois repelentes, detectaram-se diferenças significativas (P<0,05) e a antraquinona apresentou maior eficácia quando comparada ao metilantranilato, mas em mudas de milho, ambos os repelentes são iguais às propriedades repelentes. As diferenças não significantes (P>0,05) foram observadas em diferentes classificações de repelentes químicos naturais para sementes de milho, enquanto as variações significativas (P<0,05) foram observadas para as mudas de milho quando fornecidas aos pardais. Por um comportamento gravado em video, os pardais apresentaram manifestações de cabeça e vibrações de penas por consumo de sementes tratadas e mudas com maiores concentrações de repelentes de aves naturais.

Surgical Repair of Scimitar Syndrome

Scimitar syndrome (SS) is a form of partial anomalous pulmonary venous drainage that is dramatically visible on plain chest radiography (CXR). In these individuals, the entire venous drainage from the right lung enters a single anomalous large vein that descends to the inferior vena cava. This descending vein is visible on CXR as a curvilinear density along the right heart border and resembles the curved Turkish sword that gives the condition its name. SS forms part of the large spectrum of associated conditions known as venolobar syndrome. These include right lung hypoplasia or sequestered segments of right lung, congenital heart disease and various others. We report, along with our other five cases, a special case of a young woman who presented incidentally, with a murmur, at 16 years of age. Full investigation including angiography showed a large atrial septal defect (ASD) with right heart dilation and SS. She underwent surgical correction with uneventful and complete correction by baffling of the scimitar vein from its entry into the inferior vena to the left atrium through the enlarged ASD.

Chylopericardium after Cardiac Surgery

Chylopericardium after intra-thoracic surgery is rare. Its incidence is reported to be between 0.22% and 0.5%[1, 2] following paediatric cardiac surgery, but is not quantified following cardiac surgery in the adult population. A delay in diagnosis can lead to serious consequences with tamponade and death[3]. Chronic lymph leak can also lead to immunosuppresion, hypoproteinemia and malnutrition[3]. The majority of published literatures on this condition after cardiac surgery are in children. There are few reports of chylopericardium in adults following coronary artery bypass grafting and valvular surgery[4–6], and these advocate treatment with either total parental nutrition or surgical intervention. We report on the case of chylopericardium after a trial. Septal defect surgical closure in an adult patient treated successfully by oral dietary manipulation.

Giant Thymolipoma – A Rare Benign Tumour of the Thymus Gland

Thymolipoma is a rare benign tumour of mediastinum. It is often asymptomatic but can enlarge significantly prior to the diagnosis. It consists of thymic and fatty tissue surrounded by a capsule. A 23-year-old man sought medical attention for respiratory distress since 10 years progressively increasing in severity. Computed tomography findings were suggestive of a space occupying lesion in the anterior mediastinum with extension into hemi-thorax on either side. The tumour was surgically resected by median sternotomy. The tumour measured ∼21x25x10 cm and weighed 2800 gm. Histopathological examination revealed thymolipoma.

Reliability & validity of the Malayalam hospital anxiety & depression scale (HADS) in cancer patients.

BACKGROUND & OBJECTIVE: The hospital anxiety and depression scale (HADS) has been widely used on cancer patients as an indicator of psychological morbidity. Though the scale has been used in India, no reports are available on translation of HADS in any Indian language and testing the reliability. The present study describes the translation process of HADS into Malayalam and testing its reliability and validity on psychological morbidity in cancer patients. METHODS: The English version of the HADS was translated into Malayalam and was used in this study. The questionnaire was administered to 240 cancer patients and statistical analysis was carried out using Chronbach's alpha to test the internal consistency of the HADS scale while confirmatory factor analysis was carried out using principal axis factoring with equimax rotation and Kaiser Normalization to test its construct validity. RESULTS: The Cronbach's alpha was found to be 0.81 for the HADS anxiety subscale, 0.71 for the HADS depression subscale, and 0.85 for HADS tool. Confirmatory factor analysis (CFA) indicated two depression items (i.e., enjoyment and anhedonia) loading onto the anxiety subscale. Clinical caseness for anxiety was observed in 8 per cent, while 11 per cent of the patients had borderline mood disorder. Clinical caseness for depression was identified in 7.6 and 13 per cent of patients were found to have borderline mood disturbances. INTERPRETATION & CONCLUSION: This preliminary validation study of the Malayalam version of the HADS showed it as an acceptable, and reliable measure of psychological morbidity among cancer patients. The prevalence of anxiety and depression in Indian population was low and enjoyment and anhedonia might present as anxiety initially.

Diaphragmatic rupture by blunt trauma: a report of three cases

We report three cases of diaphragmatic rupture due to blunt trauma managed in our hospital during the period from September 1995 to January 2000. The injuries were due to motor-vehicle accidents. All patients were males, with ages ranging from 25 to 80 years. Two patients presented acutely with left hemidiaphragmatic rupture and stomach herniation into the thorax. Both suffered associated skeletal injuries. The third patient presented 4 years after the traumatic event with right diaphragmatic hernia that contained strangulated bowel. Postoperative complications relating to the diaphragmatic hernia occurred in the patient that presented late. These three cases underscore the importance of plain chest radiography [CXR] in the early diagnosis of this type of injury
