THE NEUROPROTECTIVE EFFECT OF TOCILIZUMAB IN BRAIN ISCHEMIA REPERFUSION INJURY

The aim: This research was conducted to assess the possible neuroprotective effect of Tocilizumab in brain ischemic reperfusion injury in rats. Materials and methods: 24 adult Sprague-Dawley rats were divided into four groups randomly. The sham group was given anesthesia at the same time as the other groups and was in the same condition as the other groups. Control group: 1 h of ischemia followed by 4 h of reperfusion. The vehicle group was the same as the control, but they were given the vehicle intraperitoneally (1 ml/kg of 0.9 % NaCl) for 7 days before the ischemia. The treatment group as the control group, but they were given tocilizumab (8 mg/ kg) intraperitoneally for 7 days before ischemia. Results: control group, inducing ischemia/reperfusion increased infarction size considerably (p<0.001), when comparison to the control and vehicle groups, tocilizumab at dose (8 mg/kg) showed a significantly (p<0.001) smaller infraction area. Conclusions: In a cerebral ischemia/reperfusion, a reduction in infarction area in injected with Tocilizumab medication was considered neuroprotective for cerebral ischemia/reperfusion.
