Effect of Seed of Cassia tora Extract in the Prevention of Remote Renal Reperfusion Injury.

Objective: Renal ischemia/reperfusion (I/R) injury is characterized by the acute deterioration of renal function during ischemia and renal inflammation. Cassia tora has various effects, including antioxidant, antidiabetic, and hypolipidemic properties. In the present study, we investigated whether C tora has a renoprotective effect on I/R-induced acute kidney injury in rats.
Methods: We fed Sprague-Dawley rats either C tora (100 mg/kg/d) or saline. One week later, ischemia was induced by bilateral renal pedicle occlusion for 30 minutes, followed by reperfusion. Rats were randomized into 3 major groups, which were treated as follows: 1. the sham operation group; 2. the I/R group; and 3. the I/R-C tora group.
Results: Compared to the sham group, the I/R group had higher levels of blood urea nitrogen and serum creatinine in serum and lower expression of catalase, superoxide dismutase, glutathione peroxidase, antioxidant, and nitric oxide. Compared to the I/R group, the I/R-C tora group had higher expression of catalase, superoxide dismutase, glutathione peroxidase, antioxidant, and nitric oxide, as well as lower levels of blood urea nitrogen and creatinine in serum.
Conclusions: These results suggest that C tora has significant therapeutic effects in ischemic renal injury.
