title: Influence of fluoride on streptozotocin induced diabetic nephrotoxicity in mice: protective role of Asian ginseng (Panax ginseng) & banaba (Lagerstroemia speciosa) on mitochondrial oxidative stress.
abstract: OBJECTIVE
  Chronic fluoride intoxication through drinking water is a serious health problem. Patients with diabetes are known to have impaired renal function and elimination of fluoride from the body is mainly done through kidney. Fluoride toxicity in diabetes patients may aggravate complications. In this study, the influence of fluoride was assessed on streptozotocin (STZ) induced diabetes in mice as also the efficacy/protective effective of oral supplementation of ginseng (GE) and banaba leaf extracts (BLE).
  
  
  METHODS
  The efficacy of plant extracts, GE and BLE at doses of 50, 150, 250 mg/kg b.w./day alone and in combination, was tested for a period of 15 days on fluoride treated STZ induced diabetic animals.
  
  
  RESULTS
  Fluoride exposure to mice with STZ-induced diabetes produced significant changes in OSI (organo-somatic index), fluoride content, blood glucose, urea, serum creatinine and oxidative stress indices in kidney tissues with evident histological alterations. Among the antioxidant treatments, combination therapy of GE and BLE at 150 mg/kg b.w. significantly normalized the impaired biochemical variables in kidney tissues of fluoride toxicated diabetic mice. INTERPRETATIONS & CONCLUSIONS: High fluoride uptake was found to be diabetogenic and further aggravated the renal oxidative damage and thereby the toxicity in mice with STZ induced diabetes mice. GE and BLE exposure individually or in combination at a dose of 150 mg/kg b.w./day for 15 days exhibited protective effects on fluoride toxicated STZ induced nephrotoxicity in mice.
