Introduction: The fate of xenobiotics that is present, increasing day by day. The increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. Methods: The present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by Panax ginse...

The relationship between reduced glutathione (GSH) level and glutathione S-transferase (GST) activity in erythrocytes was examined, using sheep erythrocytes, which have varying GSH concentrations, and dog erythrocytes with an inherited high concentration of GSH. There was a positive correlation (r = 0.529, p < 0.001) between the GSH level and GST activity in sheep erythrocytes. In dog erythrocy...

paracetamol (acetaminophen, pcm) is a widely used over-the-counter analgesic and antipyretic drug. intake of a large dose of pcm may result in severe hepatic necrosis. oxidative stress is mediated by oxidative capacities of the pcm metabolite (n-acetyl-para-benzo quinoneimine, napqi), which covalently binds to proteins and other macromolecules to cause cellular damage. at low doses, napqi is co...

The influence of histamine and quercetin, as well their combined effect on the content in whole blood, superoxide anion radical, sialic acids, sulfhydryl groups, activity catalase, glutathione peroxidase, transferase rat erythrocytes was studied. It established that quercetin at a concentration 0.1 mM causes an increase blood rats, while all other studied concentrations cause significant decrea...

Mouse glutathione S-transferase GST YfYf (an orthologue of GST P or 7-7 in the rat and of GST pi in the human) was found to have a subunit Mr of 24,500 and cross-reacted with anti-(rat GST YfYf). N-Terminal analysis showed a close similarity to the rat, human and bovine orthologues. On isoelectric focusing the native enzyme had a pI of 8.3 and a pI of 7.3 in the presence of urea. Initial-rate s...
