益精提神法治疗多发性梗塞性痴呆的实验研究

目的：探讨益精提神法治疗多发性梗塞性痴呆的作用机理。方法：采用同种大鼠无菌自然干燥血凝块颈总动脉注射及跳台反射第１次跳下潜伏期为筛选指标，成功地建立了ＭＩＤ大鼠模型。在此基础上，观察益精提神法对其学习记忆能力，血清及脑组织丙二醛含量及超氧化物歧化酶活力，脑组织学单胺递质水平以及多发性脑梗塞大鼠脑组织形态结构的影响。

Experimental Study on Multi Infarct Dementia Treated with Reinforcing Essence to Refresh Mental Activity Method

Objective: To explore the mechanism of multi infarct dementia (MID) treated with reinforcing essence to refresh mental activity method (RERM). Methods: MID rat models were established by injecting sterile dry blood clots into common carotid artery and screening by the first jumping off latency of diving platform reflex. Effect of RERM on model rats in learning, memory, serum and brain malondialdehyde (MDA), superoxide dismutase (SOD) level, brain monoamine neurotransmitter content, and brain morphosis were observed. Results: Obvious malfunction of learning and memory was found in MID rat models, and there were also significant decreasing of monoamine neurotransmitters content in partial brain zones, decreasing of SOD activity in brain and increasing of MDA content in serum and brain. RERM could obviously improve learning and memory, raise SOD activity and monoamine neurotransmitters content in brain tissue, lower MDA content in serum and brain of MID rat models, protect brain morphosis of multi infarction rats. Conclusion: RERM might treat MID by restraining lipid peroxidation, improving monoamine neurotransmitters content in partial brain zones and decreasing ischemic damage of brain tissue.
