The combined effects on the intestinal cells of guinea pigs following feeding them with lathyrus and manganese (Mn) for 90 days were studied in this investigation. Guinea pigs given Mn (4 ppm of their diets) for 90 days showed no change in either intestinal bioconstituents or marker enzymes, with the exception of gamma-glutamyl transpeptidase (GGT) and quinone reductase (QR). Exposure to a diet of 80% lathyrus only resulted in significant (p <. 05) inhibition of intestinal alkaline phosphatase (ALP), sucrase, GGT, QR, and glutathione-s-transferase (GST) along with significant (p <. 05) depletion of total hexose and phospholipids. Animals given lathyrus and Mn showed a significant (p <. 05) decrease in intestinal ALP, Ca +2 Mg +2 -ATPase, sucrase, GGT, GST, and QR along with significant (p <. 05) depletion in total hexose and phospholipids and concomitant enhancement in cholesterol when compared to controls. The data clearly indicate that combined treatment with lathyrus and Mn potentiates intestinal toxicity more than does Mn or lathyrus alone.

Recent studies reported that 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibitors have pleotropic effects independent of their lipid-lowering properties. The present study was undertaken to determine whether treatment with rosuvastatin (RO) would be beneficial in a rat model of bile duct ligation (BDL). Animals were divided into three groups: a sham group (group I), a BDL group treated with vehicle (group II), and a BDL group treated with RO (10 mg/kg) (group III). Serum levels of total bilirubin, gamma-glutamyl transpeptidase, alanine aminotransferase, and aspartate aminotransferase decreased significantly in group III when compared to group II. Lipid peroxides and NO levels of group III were found to be significantly lower than those of group II. Antioxidant enzymes (superoxide dismutase, glutathione-S-transferase, and catalase) activity in liver tissues markedly decreased in group II, whereas treatment with RO preserved antioxidant enzyme activity. DT-diaphorase activity in group II was significantly higher than that in group III. The histopathological results showed multiple numbers of newly formed bile ductules with inflammatory cells infiltration in group II. These pathological changes were improved in group III. Our data indicate that RO ameliorates hepatic injury, inflammation, lipid peroxidation and increases antioxidant enzymes activity in rats subjected to BDL. RO may have a beneficial effect on treatment of cholestatic liver diseases.
