title: Antihyperglycemic and antioxidant activities of alcoholic extract of Commiphora mukul gum resin in streptozotocin induced diabetic rats.
abstract: OBJECTIVE
  The present study investigated the effect of Commiphora mukul ethanol extract gum resin (CMEEt) on streptozotocin (STZ) induced diabetic rats by measuring fasting blood glucose, plasma insulin, plasma lipid profile, atherogenic index, hepatic lipid peroxidation (LPO), protein oxidation (PO) and activities of enzymatic antioxidants.
  
  
  METHODS
  Wistar albino rats were divided into 4 groups, normal control group, CM-treated control group, diabetic control group and CM-treated diabetic group. For induction of diabetes, STZ was administered at a dose of 55mg/kg body weight, meanwhile CM-treated groups were administered CMEEt at a dose of 200mg/kg body weight for 60 days. Body weight, plasma glucose and insulin levels were determined in different experimental days, after end of the experimental period the plasma lipid profile and antioxidant enzymes were determined in hepatic tissue.
  
  
  RESULTS
  Increase in plasma glucose, total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C), hepatic LPO and PO levels with decrease in plasma high density lipoprotein cholesterol (HDL-C), insulin, hepatic reduced glutathione (GSH) content and activities of antioxidant enzymes namely, glutathione peroxidase (GPX), glutathione reductase (GR), glutathione-S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) were the salient features observed in diabetic rats. On the other hand, oral administration of CMEEt at a dose of 200mg/kg for 60 days resulted in the prevention of above mentioned abnormalities.
  
  
  CONCLUSIONS
  The results suggest that CMEEt could be beneficial in the treatment of diabetes, characterized by atherogenous lipoprotein profile, aggravated antioxidant status and impaired glucose metabolism and in their prevention.
