Treatments with 10 and 25mg/kg dicofol produced dose-related increases of cytochrome P450 and cytochrome b (5) contents and NADPH-cytochrome c reductase, 7-ethoxyresorufin O-deethylase, pentoxyresorufin O-dealkylase, aniline hydroxylase, and erythromycin N-demethylase activities in liver microsomes.

Carbon tetrachloride pretreatment or partial hepatectomy decreased the hepatic xenobiotic-metabolizing enzyme activities in both sexes but elevated the renal p-nitrophenol hydroxylase, p-nitroanisole O-demethylase and aminopyrine N-demethylase activities significantly only in male mice.

A rat liver fibrosis model was successfully established using several inducers, including a high-fat diet, alcohol and carbon tetrachloride.
The activity of hepatic and small intestinal microsomal erythromycin N-demethylase (a marker for CYP3A) and the expression of small intestinal cyp3a and multidrug resistance (mdr) mRNA were compared between normal rats and rats with liver fibrosis. 3.

Hepatic microsomal drug metabolizing enzymes of CYP 2E1 showed sharp depletion as assessed by estimating aniline hydroxylase and amidopyrine N-demethylase activity after CCl (4) exposure.

Furthermore, the increases in the levels of microsomal ethoxyresorufin O-deethylase and erythromycin N-demethylase were accompanied with up-regulation of mdr 1a mRNA in the small intestines of hepatic fibrosis rats when compared to those of the normal rats.
Rat hepatic fibrosis model was successfully induced using complex factors including carbon tetrachloride, ethanol and high fat.

Aim: The curative effect of emodin (1,3,8-trihydroxy-6-methyl anthraquinone), an active compound of the plant species Ventilago maderaspatana Gaertn, was evaluated against carbon tetrachloride (CCl (4)) induced hepatic cytochrome P450 (CYP) enzymatic and ultrastructural alterations in rats.
Exposure to CCl (4) diminished the activities of CYP enzymes (i.e. aniline hydroxylase and amidopyrine-N-demethylase and microsomal protein contents with concomitant increase in microsomal lipid peroxidation).

Likewise, CCl (4) treatment reduced the microsomal p-nitrophenol hydroxylase and p-nitroanisole O-demethylase activities to less than one third of control.

DMSO induced the microsomal p-nitrophenol hydroxylase and p-nitroanisole O-demethylase activities as early as 2 h following the treatment.

Multiple treatment of propolis significantly prevented the release of transaminases, alkaline phosphatase, lactate dehydrogenase, gamma-glutamyl transpeptidase, urea and uric acid in serum; improved the activity of hepatic microsomal drug metabolizing enzymes, i.e., aniline hydroxylase and amidopyrine-N-demethylase; significantly inhibited lipid peroxidation and markedly enhanced glutathione in liver and kidney as well as brought altered carbohydrate contents (blood sugar and tissue glycogen), protein contents (serum, microsomal and tissue protein) and lipid contents (serum and tissue triglycerides, serum cholesterol, total and esterified cholesterol in tissue) towards control.

Hepatoprotective potential was confirmed by the restoration of lipid peroxidation, glutathione, glucose-6-phosphatase and microsomal aniline hydroxylase and amidopyrine N-demethylase towards near normal.
