Effect of combined Atorvastatin and zinc oxide on the biochemical and histopathological alterations in kidney of diabetic rats
Background and ObjectiveDiabetic mellitus nephropathy is one of the most important implication factors in kidney´s physiological function in diabetes mellitus. Having major role in filtration, in hyperglycemic condition kidney has shown more damages in comparison with other tissues. This study was done to determine the effect of combined Atorvastatin and Zinc oxide on the biochemical and histopathological alterations in kidney of diabetic rats.
MethodsIn this experimental study, 40 female Wistar rats were randomly allocated into five groups including normal control (NC), diabetic control (DC), diabetic rats treated with atorvastatin (20mg/kg/bw daily, orally) (D+A), Zinc oxide (30mg/kg/bw daily, orally) (D+Z) and combination of each drug in half dose (daily, orally) (D+A+Z). Diabetes induced in rats by a single intraperitoneal injection of 60mg/kg/bw streptozotocin-diabetic.Animals treated for one month. At the end of the study, kidney weight and body weight and biochemical factors including creatinine and urea were measured to assess renal function. For determing the histopathology of kidney tissue, sections with 4-5 micrometer were stained with hematoxylin and eosin.
ResultsThe level of serum creatinine and urea was significantly increased in diabetic rats in compare to controls (P<0.05). Treatment of diabetic rats with half doses of combination of atorvastatin and Zinc oxide reduced the level of creatinine, urea and renal tissue damage in comparision with diabetic rats without treatment (P<0.05).
ConclusionThis study showed that the combination of atorvastatin and Zinc oxide has effect on controlling diabetic nephropathy.
