effect of pimpinella tirupatiensis on oxidative enzymes in stz-induced diabetic rat kidney

the present study was aimed to evaluate the therapeutic potential of pimpinella tirupatiensis (pt) by assaying the activities of selective mitochondrial enzymes in streptozotocin induced diabetic rats. diabetic rats showed a significant (p < 0.01) reduction in the activities of oxidative enzymes succinate dehydrogenase (sdh), malate dehydrogenase (mdh), glutamate dehydrogenase (gdh) and isocitrate dehydrogenase (icdh). lactate dehydrogenase (ldh) activity was significantly (p < 0.01) increased in diabetic rats. the daily oral treatment of pimpinella tirupatiensis ethyl alcohol extract (750 mg/kg body weight/day) to diabetic rats for 30 days reversed the above changes in a significant (p < 0.01) manner. from our observations, we conclude that administration of pt altered the activities of oxidative enzymes, thereby suggesting its role in mitochondrial energy production. the obtained results were compared with glibenclamide, a standard anti diabetic drug. thus, the modulatory effects of pt on altering these enzymes activities afford a promise for widespread use for treatment of diabetes in the future.
