Described are the susceptibility of the Indian langur (Presbytis entellus) to Leishmania donovani and the consequent haematological and serum biochemical changes. The host response to antileishmanial chemotherapy and the immunological profile were also examined. Each langur was inoculated intravenously with 1 x 10(8) amastigotes; a spleen biopsy carried out(More)
UNLABELLED Hepatotoxicity is one of the most serious adverse effects of antituberculosis drugs. The aim of this study was to produce a rat model of isoniazid-rifampicin (INH-RIF) induced hepatotoxicity. MATERIALS AND METHODS Wistar rats (100-150 g) were treated with different doses of INH i.e. 25, 50 and 75 mg/kg/day with a fixed dose of RIF i.e. 50(More)
The present article reviews the historical and popular uses of garlic, its antioxidant, haematological, antimicrobial, hepatoprotective and antineoplastic properties and its potential toxicity (from sulfoxide). Garlic has been suggested to affect several cardiovascular risk factors. It has also been shown that garlic and its organic allyl sulfur components(More)
UNLABELLED Accidental/suicidal ingestion of corrosive substances is common in North India. Decreased gastric secretion and delayed gastric emptying in the chronic phase of corrosive injury has been documented at our center. We hypothesize that patients in the chronic phase of corrosive injury may have delayed orocecal transit time (OCTT). OBJECTIVE To(More)
Several novel type of lipopeptides were synthesized and evaluated for their ability to stimulate non-specific resistance against Leishmania donovani infection. Peritoneal macrophages isolated from young male hamsters treated with muramyl dipeptide (MDP) and various synthetic lipopeptides (6 mg/kg i.p.) 7 days earlier, were cultured in vitro and challenged(More)
AIM To evaluate the hepatoprotective effect of garlic on liver injury induced by isoniazid (ZNH) and rifampicin (RIF). METHODS Wistar rats weighing 150-200 g were treated orally with 50 mg/kg of INH and RIF daily each for 28 d. For hepatoprotective studies, 0.25 g/kg per day of freshly prepared garlic homogenate was administered orally half an hour before(More)
Susceptibility of animals to infections depends upon various factors including sex of the host which plays a pivotal role. The intake of L. donovani was investigated in male and female hamsters as also in gonadectomized and hormone (sex) treated animals. Male hamsters developed more parasites (55/100 cell nuclei) than their female counterparts (22/100 cell(More)
AIM To study the role of N-acetylcysteine (NAC) as a protective agent in rifampicin (RMP)-induced oxidative hepatic injury of young rats. METHODS Hepatic injury was produced by giving 50 mg/kg body weight/day of RMP for 3 wk. A dose of NAC (100 mg/kg body weight/day) was given in combination with RMP intraperitoneally. Analysis of lipid peroxidation,(More)
This study evaluates the hepatoprotective effect of carotenoids against isoniazid (INH) and rifampicin (RIF). Thirty-six adult rats were divided into the following 4 groups: (1) control group treated with normal saline; (2) INH + RIF group treated with 50 mg·(kg body mass)-1·day-1 of INH and RIF each; (3) INH + RIF+ carotenoids group treated with 50 mg·(kg(More)
INTRODUCTION Acute generalised peritonitis coming forth due to underlying intestinal perforation is a critical & life-threatening medical condition. It is a common surgical emergency most of the times across the world. Misleading data on crude morbidity and mortality due to the condition usually contaminates substantially the very purpose of medical audit.(More)
