    Abstract:
    Digera muricata (L.) Mart. is a weed and commonly found in waste places, road sides and in maize fields during the summer season. It possesses antioxidant capacity and is locally used for various disorders such as inflammation, urination, as refrigerant, aperient and in sexual anomalies. In this study antioxidant potential of Digera muricata methanol extract (DMME) and n-hexane extract (DMHE) was evaluated against CCl(4)-induced oxidative stress in adrenal gland of Sprague-Dawley male rats. 42 rats were equally divided into 7 groups of 6 rats in each. Group I remained untreated, while Group II treated with vehicles. Group III received only CCl(4) (1 ml/kg b.w., 10% in olive oil) once a week for 16 weeks. Group IV and VI received DMME and DMHE at a dose of 200 mg/kg b.w. along with CCl(4). Animals of Group V and VII administered with DMME and DMHE alone at a dose of 200 mg/kg b.w. once a week for 16 weeks. Lipid peroxidation significantly increased while activities of antioxidant enzymes (CAT, SOD, GST, GSR and GSH-Px) were reduced in adrenal gland samples by the administration of CCl(4). Glutathione (GSH) concentration was significantly decreased whereas DNA fragmentation% and AgNORs count was increased in adrenal gland by CCl(4) administration. Treatment of rat by both the extracts (DMME, DMHE) and CCl(4) increased the glutathione level and activities of antioxidant enzymes while reduced the lipid peroxidation, DNA fragmentation percent and AgNORs count in adrenal gland. These results indicate that Digera muricata extract is able to ameliorate oxidative stress in adrenal gland induced by CCl(4) in rat.
