- W2395600087 abstract "This investigation was performed to evaluate the effects of nimesulide (NIM), a selective cyclo-oxygenase-2 (COX-2) inhibitor, on forebrain ischemia-induced in vivo oxidative stress damage in the rat hippocampus. Hippocampal tissue glutathione (GSH) and malondialdehyde (MDA) contents, the activities of the antioxidants superoxide dismutase (SOD) and catalase as well as nitric oxide (NO) concentration were estimated. A clinically relevant dose of NIM (18 mg x kg(-1) x d(-1), p.o.) was administered immediately after induction of forebrain ischemia for 7 consecutive days. Forebrain ischemia induced oxidative stress after 7 days manifested by significant decrease in GSH and increase in MDA levels as compared to control (p < 0.05). Also, in rats subjected to ischemia, SOD and catalase activities were decreased significantly compared to the control group (p < 0 .05). On the other hand, ischemic rats showed a significant increase in NO concentration compared to those in the control group (p < 0.05). Treatment with NIM protected the rats from ischemia-induced oxidative stress as evident by normalization of measured parameters. The present study indicates the ability of NIM to reduce oxidative stress induced by transient forebrain ischemia. This suggests that the induction of COX-2 might be involved in transient forebrain ischemia-induced oxidative damage and hence the selective COX-2 inhibitors might be a valuable therapeutic strategy against ischemic brain injury." @default.
