This study has involved many phytochemical tests such as characterization of 20% methanolic extract of each plants which has been carried out by thin layer chromatography, detection phytochemical compounds and antioxidant activity test. Furthermore, cytogenetic and molecular study was carried out which included determination of mitotic index, chromosome aberration, and DNA fragmentation test of DNA extracted from WBC and renal cortex. On the other hand, insulin receptor and insulin receptor substrate-1 genes had been detected in all treatment and control groups. Also, histopathological changes in pancreas, liver, and kidney were studied.
