This study was undertaken to investigate the putative antioxidant activity of the oyster mushroom Pleurotus ostreatus on CCl(4)-induced liver damage in male Wistar rats. Intraperitoneal administration of CCl(4) (2ml/kg) to rats for 4 days resulted in significantly elevated (p<0.05) serum levels of glutamic oxaloacetic transaminase (SGOT), glutamic pyruvate(More)
PURPOSE OF REVIEW Infectious keratitis is a medical emergency. Improper management can lead to marked loss of vision. This review identifies recent trends in the study of infectious keratitis. RECENT FINDINGS A multicountry outbreak of Fusarium keratitis emphasizes that contact lens wear is a major risk factor for infectious keratitis. Acanthamoeba and(More)
The present study sought to determine whether acetyl-L-carnitine (ALCAR) prevents selenite cataractogenesis by mechanisms involving lenticular calpain activity, Wistar rat pups were divided into 3 groups of 15 each. Group I (normal) rats received an intraperitoneal (i.p.) injection of normal saline on postpartum day 10; Group II (cataract-untreated) rats(More)
The present study sought to evaluate the efficacy of the naturally-occurring polyphenol, ellagic acid, in preventing selenite-induced cataractogenesis. In the present study, Wistar rat pups were divided into 3 groups of 15 each. Group I (normal) rats received an intraperitoneal (i.p.) injection of normal saline on postpartum day 10; group II(More)
PURPOSE To investigate whether acetyl-L-carnitine (ALCAR) retards selenite-induced cataractogenesis in vivo. METHODS On postpartum day 10, group I pups received intraperitoneal saline and group II and group III pups received subcutaneous sodium selenite; Group III pups also received intraperitoneal ALCAR once daily on postpartum days 9-14. Both eyes of(More)
The present work is aimed at evaluating the protective effect of the oyster mushroom, Pleurotus ostreatus on carbon tetrachloride (CCl4)-induced toxicity in male Wistar rats. Significantly elevated mean levels (p<0.05) of malondialdehyde (MDA) and lowered mean levels (p<0.01) of reduced glutathione (GSH), vitamins C and E (p<0.05) were observed in kidneys,(More)
The present study was performed to investigate the toxic impact of carbaryl on biochemical metabolism in the hemolymph, brain, hepatopancreas, gills and muscle of intermoult juveniles of the economically important prawn, Macrobrachium malcolmsonii. The concentration of glutathione S-transferase (GST) was found to be higher in test prawns when compared with(More)
The present study examined alterations in the protein pattern and histopathology of the hepatopancreas and gills of Macrobrachium malcolmsonii following exposure to Sevin, the commercial grade of carbaryl (1-Naphthylmethyl carbamate) pesticide. Juvenile prawns were exposed to sub-lethal concentrations 5.15 microg l(-1), 7.73 microg l(-1) and 15.47 microg(More)
In the present study, the efficacy of green tea catechins (GTC from the plant Camellia sinensis), with epigallocatechin gallate (EGCG), as the major component, was studied in relation to hepatic oxidative abnormalities in atherosclerotic rats. When male albino Wistar rats were fed an atherogenic diet for 30 days and then treated with saline for 7 or 15(More)
In diabetes mellitus (DM), sustained hyperglycemia results in the generation of reactive oxygen species, ultimately leading to increased oxidative stress and inflammation in vital tissues. In the present study, possible ameliorative effects of naringenin on hyperglycemia-mediated inflammation in experimental streptozocin (STZ)-nicotinamide-induced DM were(More)
