Protective Effect of Hypericum perforatum L. Extract on Hexavalent Chromium Induced Toxicity in Rat Adrenal Gland

摘要

This study was carried out to test the possibility of hexavalent chromium administration through drinking water to induce the structural damage in rat's adrenal glands and the possibility of Hypericum perforatum extract to faith against chromium aggression. Chromium induced cellular stress was determined by the expression level assessment of the Bcl2 genes family, known to modulate the apoptotic pathway. Obtained results showed that exposure to chromium altered adrenal glands morphology, by induction of apoptosis. When Hypericum perforatum extract was administered expression level of Bcl2 genes and histological lesions in adrenal glands were significantly reduced.
