OBJECTIVE To evaluate the antidiabetic activity of an aqueous extract of the roots of Hemidesmus indicus on blood glucose, serum electrolytes, serum marker enzymes, liver microsomal P-450 enzymes, and lipid peroxidation in the liver and kidney of streptozotocin-induced diabetic rats. MATERIALS AND METHODS Effect of H. indicus extract on blood glucose was studied with fed, fasted and glucose-l...

objective(s):the current study was aimed to determine the bioactive constituents and biological effects of the crataegus monogyna ethanolic extracts from bark, leaves and berries on hypercholesterolemia. materials and methods: oleanolic acid, ursolic acid, quercetin and lupeol concentrations were quantified by hplc. total phenol content and radical scavenging activity of extracts were also meas...

abstract        background and objectives: nonalcoholic fatty liver disease is the most common chronic liver disorder and is also currently considered as the hepatic manifestation of metabolic syndrome. regular exercise training may decrease fatty liver disease complications, although its impact is not yet clear. this study aimed to evaluate the effects of six weeks of aerobic training on liver...

Phase II conjugating enzymes play key roles in the metabolism of xenobiotics. In the present study, RNA sequencing was used to elucidate hepatic ontogeny and tissue distribution of mRNA expression of all major known Phase II enzymes, including enzymes involved in glucuronidation, sulfation, glutathione conjugation, acetylation, methylation, and amino acid conjugation, as well as enzymes for the...

Nicardipine hydrochloride (Nic), a calcium channel antagonist, is used for the treatment of hypertension. In the present study, we estimated its effects on the levels and activities of hepatic cytochrome P450 isoforms in spontaneously hypertensive rats given p.o. with Nic at a dose of 0.5, 2.5, 5, or 12.5 mg/kg at 24-hr intervals for 14 days. Therapeutic effects on the development of hypertensi...

Hepatic lipid synthesis is known to be regulated by food consumption. In rodents fasting decreases the synthesis of cholesterol as well as fatty acids. Refeeding a high carbohydrate/low fat diet enhances fatty acid synthesis by 5- to 20-fold above the fed state, whereas cholesterol synthesis returns only to the prefasted level. Sterol regulatory element binding proteins (SREBPs) are transcripti...

Objective: The long-term sequelae of methotrexate (MTX) remain the major cause of concern for both patients and therapists. Therefore, new approaches to decrease MTX side effects are needed. The study was carried out to evaluate the effects of Iris songarica Schrenk (IS) rhizome extract against MTX-induced hepatic and renal injuries in rats. Materials and...

Selenium deficiency in rats for a period of up to 6 weeks inhibited both the production of 3,3',5-tri-iodothyronine (T3) from thyroxine (T4) (5'-deiodination) and also the catabolism of T3 to 3,3'-di-iodothyronine (5-deiodination) in liver homogenates. The hepatic stores of T3 were decreased by only 8% in selenium deficiency, despite the T3 production rate from T4 being only 7% of the rate foun...
