Ginkgo biloba extract was evaluated for prophylactic value against renal ischemia-reperfusion induced oxidant stress in rat subjected to transient unilateral renal artery ligation. Oral Ginkgo biloba treatment (2mg/kg) was administered by different schedule before experimental induction of ischemia-reperfusion injury. Malondialdehyde has been taken as indicator for free radical damage produced by ischemia-reperfusion injury. Three hour pretreatment by the drug has most prominent inhibitory effect on consequent tissue and plasma malondialdehyde level of lipid peroxidation. Further, the relative inhibition of malondialdehyde level in tissue and plasma allow to infer drug effect on generation, but not the clearance of malondialdehyde. No significant difference of outcome from 1, 2 and 3 days treatment indicate no cumulation and thus safety in that respect. Ginkgo biloba treatment appears both effective and safe for prophylaxis of reperfusion injury following ischemia catastrophies.
