Histopathological study on the effects of turmeric (Curcuma longa linn.) powdwer on renal ischemia-reperfusion injuryin rats

Abstract

Renal ischemia/reperfusion (I/R) injury is a major cause of acute renal failure (ARF), which is faced in many clinical situations. This study was designed to investigate the effect of pre-treatment with turmeric (Curcuma longa linn) powder on kidney histopathology and function markers in renal ischemia / reperfusion (IR) induced injury in the rats. A total of 80 male Wistar rats were randomly divided into 4 groups: sham, IR model and two I/R+TREE (2%and4%) - treated groups (n=20 per group). I/R groups’ kidneys were subjected to 60 min of global ischemia at 37oc followed by 30min of reperfusion. After 24h of reperfusion period, the rats were sacrificed. Kidney function tests and histopathological examination were also performed. Results were compared with a group of rats with sham operation. High serum creatinine, blood urea nitrogen and uric acid were observed in I/R rats compared to the sham rats. Pre-treatment of turmeric powder for 30 days prior to IR operation improved renal function reduced IR induced renal inflammatory and oxidative injury. The results of this study showed that turmeric powder significantly prevented renal I/R-induced functional and histological injuries.
