Abstract

Abstract : Tinospora rumphii ( T. rumphii ) is a folkloric medicinal plant that is widely distributed in Asia and Africa. It has been widely used by locals to treat many diseases including jaundice, which is a manifestation of liver damage. We investigated the action of T. rumphii crude extract together with zinc sulphate, a known tumor modulator, on hepatic injuries induced by intraperitoneal ( i.p ) injections of quinoline on albino mice. The hepatotoxic effect was assessed by bilirubin concentration in the blood serum, while the genotoxic effect was determined by single-cell gel electrophoresis (SCGE). The mice orally fed with the crude extracts, following quinoline exposure, had reduced serum bilirubin concentration and DNA damage. Mice treated with Zinc sulphate, on the other hand, had remarkably reduced DNA damage on hepatocytes. Our findings showed that hepatoprotective potential of T. rumphii extract is dose-dependent and that utilization of the extract as medicinal remedy must be strictly monitored, while zinc was proven to reverse genotoxic effect of quinoline. This study unraveled the potential of T. rumphii extract and zinc as important hepatoprotective agents for future treatment of hepatic damage caused by chemotherapeutic agents used in cancer treatment.
