Uranium, the heaviest of the naturally occurring elements is widely present as environmental contaminant from natural deposits, industrial emissions and most importantly from modern weapons. Histopathological examinations revealed that uranyl nitrate (UN) exposure caused severe damage to pars recta of renal proximal tubule. However, biochemical events(More)
BACKGROUND Nephrotoxicity is a severe complication in patients undergoing cisplatin (CP) chemotherapy. Previous studies in our lab have shown that administration of a single dose of CP results in decrease in the activities of brush border membrane (BBM) and free radical scavenging enzymes and induces oxidative stress in rat kidney. Nigella sativa, is one of(More)
BACKGROUND AND PURPOSE Stress-induced central effects are regulated by brain neurotransmitters, glucocorticoids and oxidative processes. Therefore, we aimed to evaluate the simultaneous alterations in the monoamine and antioxidant systems in selected brain regions (frontal cortex, striatum and hippocampus) at 1 hour (h) and 24h following the exposure of(More)
BACKGROUND Ischemia results in rapid decline in mitochondrial electron transfer, resulting in decreased ATP levels, and fall in intracellular pH. The purpose of the study was to examine the effects of ischemia and reperfusion on the activities of enzymes of carbohydrate metabolism in rat kidney. METHODS Ischemia was induced by occlusion of the left renal(More)
Cisplatin (CP) is a major antineoplastic drug for the treatment of solid tumors, however, dose dependent nephrotoxicity remains the major concern for its long term use. Several agents/strategies were attempted to prevent CP nephrotoxicity but were not found suitable for clinical practice. Dietary fish oil (FO) enriched in ω-3 fatty acids has been shown to(More)
Cisplatin (CP) is an effective chemotherapeutic agent that induces gastrointestinal toxicity. Nigella sativa oil (NSO) has been shown to be beneficial in a wide range of gastrointestinal disorders. The present study investigates the possible protective effect of NSO on CP-induced gastrointestinal toxicity. NSO administration (2ml/kg bwt, orally), prior to(More)
Gentamicin (GM), an antibiotic against life threatening bacterial infection, induces remarkable toxicity in the kidney. Histological studies have indicated that mitochondria, microsomes, lysosomes and plasma membranes of renal proximal convoluted tubules in particular are major GM targets. Despite numerous investigations, the biochemical/cellular basis of(More)
Lead is a heavy metal widely distributed in the environment. Lead is a ubiquitous environmental toxin that is capable of causing numerous acute and chronic illnesses. Human and animal exposure demonstrates that lead is nephrotoxic. However, attempts to reduce lead-induced nephrotoxicity were not found suitable for clinical use. Recently, flaxseed oil (FXO),(More)
The altered expression of SHP-1 (SH2 domain-containing protein tyrosine phosphatase) as a consequence of promoter hypermethylation or mutations has evidently been linked to cancer development. The notion of being a cancer drug target is conceivable as SHP-1 negatively regulates cell cycle and inflammatory pathways which are an inevitable part of oncogenic(More)
An increasing number of galectins have been found in various animal species, the most abundant of which is galectin-1. The purpose of the present study was to purify and characterize galectin-1 from buffalo brain. We purified the galectin using a combination of ammonium sulphate fractionation and affinity chromatography and the homogeneity was determined by(More)
