ABSTRACT
Objective This experiment was designed to determine the effect of haloperidol on HSP70 induced by ketamine, and to explore the possibility of using haloperidol to prevent or treat the brain injury caused by ketamine.Methods 48 rats were divided into 8 groups, In group 1-3 different doses of haloperidol (1.0,5.0,10.0 mg/kg)were given 1h before the administration of ketamine. There were two control groups. In control group 1 normal saline was given twice with 1h interval between the two injections. In control group 2 ketamine 80.0 mg/kg was given 1h after the administration of normal saline.The volume of each injection was 3ml and intraabdominal injection was used as the route of administration.HSP70 mono-clone antibody immunocytochemistry was used to detect HSP70 expression in rat hippocampus, and MIAS-2000 photography analytic software to analyze HSP70 expression in hippocampus of the rat brain.Results Ketamine induced HSP70 expression in the rat brain. Pretreatment with haloperidol inhibited HSP70 expression induced by ketamine, and the inhibition was dose-dependent, but haloperidol given after the administration of ketamine could not decrease HSP70 expression.Conclusions Ketamine injures neurons of rat hippocampus and induces the expression of HSP70 and haloperidol pretreatment can prevent neuronal injury caused by ketamine, but haloperidol can not antagonize the injury caused by ketamine.
