Background: is known to exhibit protection against oxidative damage due to its rich content of compounds with antioxidant activity. This study investigated the protective effect of the methanol extract of(MO) in a rat model of renal ischemia-reperfusion (IR) injury.
Methods: Forty two wistar rats were randomly assigned to six groups of seven rats each, as follows: A, control group; B, sham-operated group; C, IR group; D, IR + low dose (200 mg/kg) MO; E, IR + high dose (400 mg/kg) MO and F, IR + Vitamin C (200 mg/kg). Unilateral ischaemia was induced by occluding the left renal artery for 45 minutes followed by reperfusion up to 24 hours.
Results: significantly (p<0.05) ameliorated IR-induced increases in malondialdehyde (MDA), protein carbonyls (PC) and advanced oxidation protein products (AOPP), while also decreasing serum BUN and Creatinine levels. Moreover, the low dose of MO caused reductions in renal NO and HOlevels, while increasing renal GPx and GST activities. Histopathology revealed marked improvement of tissue alterations induced by IR with both doses of MO.
Conclusion: Overall, the methanol extract ofeffectively attenuated the deleterious effects of renal IR via alleviation of tissue oxidative stress.
