对衰老的研究大体分为三个时期:本世纪40年代以前以病理形态学研究为主;50年代以生理功能和生化研究为主;目前已进入分子生物学研究时期。研究者提出了300多种理论和假说,试图以各种观点来解释衰老的本质和机制。与此同时,人类谋求长寿的实践活动也五花八门,从锻炼热到气功热,从吃素热到维生素E热、药膳热、花粉热……此起彼伏,交叉共存。每一种表面上的热浪总是联系着一种试探性的学
The research on aging can be divided into three periods: the pathological morphology was mainly studied before the 40s of the 20th century; the physiology and biochemistry research was the dominant one in the 1950s; and the period of molecular biology has been entered. The researchers put forward more than 300 kinds of theories and hypotheses in an attempt to explain the nature and mechanism of aging from various perspectives. At the same time, human activities to seek longevity are varied, from exercise to qigong hot, from vegetarian to vitamin E hot, medicated hot, hay fever ... ... one after another, cross coexistence. Every superficial heat wave is always associated with a heuristic
