the isolated perfused rat liver (iprl) model has been used into toxicology study of rat liver. this model provides an opportunity at evaluation of liver function in an isolated setting. studies showed that cd, in a dose-dependent manner, induced toxic effects in iprl models, and these effects were associated with aminotransferase activity and lipid peroxidation. the aim of this study was to inv...

the present study aimed to evaluate the protective effect of crocin on gastric mucosal lesions caused by ischemia-reperfusion (i/r) injury in rats.forty male rats were randomly divided into sham, control (i/r injury) and three crocin-pretreated groups. to induce i/r lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 3 h. pretreated-rats rec...

BACKGROUND: Cholestasis caused by obstruction of the common bile duct and may developed gut-derived sepsis due to reactive oxygen species (ROS) accumulation. Ursodeoxycholic acid (UDCA) glutathione are widely known for their antioxidant properties, that might be beneficial against ROS. However, effects UDCA-glutathione combination ROS have not been well elucidated in previous studies. Thus, thi...

Damaged dental pulp undergoes oxidative stress and 4-hexylresorcinol (4HR) is a well-known antioxidant. In this study, we aimed to evaluate the therapeutic effects of 4HR ointment on damaged pulp. Pulp cells from rat mandibular incisor were cultured treated with or resveratrol (1–100 ?M). These treatments (10–100 ?M) exerted protective effect during subsequent hydrogen peroxide treatments. The ...

This work is the next step in studying interplay between C-2028 (anticancer-active unsymmetrical bisacridine developed our group) and glutathione S-transferase/glutathione (GST/GSH) system. Here, we analyzed concentration- pH-dependent GSH conjugation of rat liver microsomes cytosol. We also applied three recombinant human GST isoenzymes, which altered expression was found various tumors. The f...

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 ginseng ...

A monoclonal antibody against rat liver glutathione S-transferase B, which consists of subunits Ya (Mr 27,000) and Yc (Mr 29,500), was produced in a mouse hybridoma system. The monoclonal antibody, BE6Yc1, was of the immunoglobulin G1 class and specifically recognized glutathione S-transferase B showing no cross-reactivity against the dimeric form of Ya, ligandin, in enzyme-linked immunosorbent...
