引言:人为什么会衰老?自古以来有许多假说和设想。大脑控制中心学说认为下丘脑和垂体起着衰老中心作用。改变机体中神经递质的平衡,可以阻止或逆转动物的衰老过程。1972年美国Robinson发现人脑MAO(单胺氧化酶)活性随年龄增高。40—45岁后其活性急剧上升,去甲肾上腺素含量则下降。1979—1980年Shen用试验证实了MAO是导致衰老的祸根,并寻找其抑制剂。自从1950年以来罗马尼亚科学家Aslan用Procain—Hcl以及GH_3(含2％Procain—Hcl及微量苯甲酸、偏硫酸氢钾及磷酸钠,是一种弱的,可逆的和有竞争性的MAO抑制剂)治疗老年人神经系统出现的病症如抑郁症,
Introduction: Why people become old? Since ancient times there are many hypotheses and ideas. Brain Control Center doctrine that the hypothalamus and pituitary play the role of aging center. Changing the balance of neurotransmitters in the body can stop or reverse the animal’s aging process. 1972 American Robinson found that human brain MAO (monoamine oxidase) activity with age. After 40-45 years of age its activity rose sharply, norepinephrine decreased. 1979-1980 Shen experiments confirmed that MAO is the curse of aging and looking for its inhibitors. Aslan, a Romanian scientist since 1950, is a weak, reversible and competitive MAO inhibitor with Procain-Hcl and GH_3 (containing 2% Procain-Hcl and trace amounts of benzoic acid, potassium metabisulfate and sodium phosphate) Treatment of the elderly nervous system disorders such as depression,
