The present study has been conducted to evaluate the curative effect of propolis extract, a honey bee-hive product, against acetaminophen (APAP) induced oxidative stress and dysfunction in liver and kidney. Animals were challenged with APAP (2 g/kg, p.o.) followed by treatment of propolis extract (100 and 200 mg/kg, p.o.) once only after 24 h. Release of transaminases, alkaline phosphatase, lactate dehydrogenase, and serum bilirubin were increased, whereas hemoglobin and blood sugar were decreased after APAP administration. Antioxidant status in both the liver and kidney tissues were estimated by determining the glutathione, malondialdehyde content and activities of the CYP enzymes, which showed significant alterations after APAP intoxication. In addition, activities of adenosine triphosphatase, acid phosphatase, alkaline phosphatase, and major cell contents (total protein, glycogen and cholesterol) were also altered due to APAP poisoning. Propolis extract successfully reversed the alterations of these biochemical variables at higher dose. Improvements in hepatorenal histoarchitecture were also consistent with biochemical observations. The results indicated that ethanolic extract of propolis has ability to reverse APAP-induced hepatorenal biochemical and histopathological alterations probably by increasing the antioxidative defense activities due to various phenolic compounds present in it.

D003577 Cytochrome P-450 Enzyme System A superfamily of hundreds of closely related HEMEPROTEINS found throughout the phylogenetic spectrum, from animals, plants, fungi, to bacteria. They include numerous complex monooxygenases (MIXED FUNCTION OXYGENASES). In animals, these P-450 enzymes serve two major functions: (1) biosynthesis of steroids, fatty acids, and bile acids; (2) metabolism of endogenous and a wide variety of exogenous substrates, such as toxins and drugs (BIOTRANSFORMATION). They are classified, according to their sequence similarities rather than functions, into CYP gene families (>40% homology) and subfamilies (>59% homology). For example, enzymes from the CYP1, CYP2, and CYP3 gene families are responsible for most drug metabolism.
