Involvement of Central Histaminergic System in Memory Deficits after Isoflurane Anesthesia
摘要
Abstract
Objective; To explore whether histaminergic system participates in memory deficits after isoflurane anesthesia. Methods; The effect of isoflurane on post-anesthesia memory was investigated in male SD rats with one-trial inhibitory avoidance model. The role of histaminergic pathway in isoflurane anesthesia induced memory deficits was explored by microinfusion of GABAA receptor antagnist bicucculline methiodide ( BMI) into tuberomammillary nucleus (TMN). The expression of brain-derived neurotrophic factor (BDNF) in hippocampus was assessed by western blot. Results: The step-through latency and the expression of BDNF decreased after isoflurane anesthesia. The changes were reversed by microinfusing of BMI into TMN 10 min before one-trial inhibitory avoidance training. Conclusion; Central histaminergic system and its mediated BDNF expression in hippocampus may participate in the memory deficits after isoflurane anesthesia.关键词
