Background: Cerebral ischemia/ reperfusion leads to programmed cell death or planned apoptosis. Hippocampus is a very sensitive tissue to cerebral ischemia. Propofol is an anesthesia that recently the use of this drug as a neuroprotective has been considered. In this study, the effect of propofol on CA2 and CA3 areas of the hippocampus following ischemia was investigated.
Materials and methods: 24 Wistar rats were randomly divided into 4 groups, including: control ischemia, experimental and vehicle. The experimental group received 40 mg/ kg of propofol and the vehicle group received 1 ml normal saline 1 hour before ischemia intraperitoneally. The ischemic model was performed by bilateral closure of the common carotid arteries for 20 minutes then reperfusion was done. 4 days later, all rats were sacrificed and the hippocampal tissue was examined by Nissl staining method. Data were analyzed using SPSS-25 statistical software by one-way ANOVA and TUKEY test. p<0.05 was considered as Significant.
Results: Ischemia/ reperfusion for 20 minutes caused degeneration of pyramidal cells in CA2 and CA3 hippocampus and these neurons showed a significant decrease compared to the control group, but propofol injection inhibited the decrease in the number of viable cells in these two areas.
Conclusion: Propofol can be used as an effective agent in preventing or reducing the complications of stroke alone or with other drugs.
