衰老是生命过程中正常的生理现象,大量实验表明,自由基及其引起的脂质过氧化反应是引起生物衰老的主要原因。是机体各器官功能普遍的、逐渐降低的过程。表现为精神不振、健忘、形寒肢冷、纳差少眠、腰膝无力、气短乏力,甚则面浮肿等。海马与空间学习记忆功能密切相关,还对记忆各种新知识起关键调节作用。本文探讨刺五加对D-半乳糖致衰老大鼠海马神经元损伤保护的形态学改变。1材料与方法1.1动物8周龄(180~200g体重)SD大鼠。由沈
Aging is a normal physiological phenomenon in life. A large number of experiments show that free radicals and their lipid peroxidation are the main causes of biological aging. Is the body of various organ functions generally, gradually reduce the process. Manifest for the lack of energy, forgetfulness, cold limbs, poor appetite, waist and knee weakness, shortness of breath, and even face edema. The hippocampus is closely related to spatial learning and memory, and plays a key regulatory role in memory of various new knowledge. This article explored the morphological changes of Hippocampal neurons damaged by Acanthopanax senticosus in D-galactose-induced aging rats. 1 Materials and methods 1.1 Animals 8 weeks old (180 ~ 200g body weight) SD rats.
