二、延缓衰老实验研究
当前,科学家们正从不同角度,采用不同方法,进行多方面
的实验研究、探索,以揭开人类寿命之奥密
一) 제주출장마사지 。如用抗 衰老药物或其他药物,增加细胞分裂次数或延长细胞分裂周期, 从而达到长寿。经实验初步证实,在实验培养的人肺细胞的培养 基中添加维生素 E,就可使这细胞的分裂次数增加到 120 次以上。 又如用氢化考的松等药物可使细胞的分裂次数由 50 次增加到 70
次。
有的科学家认为,延长胸腺功能,人的寿命也会延长。实验
证实,将新生小鼠的胸腺切除,其生存期便从原来的三年缩短为 六个月,而垂体退化的保儒鼠在注射一次淋色细胞后,则可使它 们的寿命延长三倍,故目前有的学者实验,将年轻人的胸腺T细 胞取出冰冻储存起来,过 40 ~50 年以后,当这个年轻人衰老之 后,再将解冻的胸腺T细胞注射进去,这样会恢复其青春的活力,
提高免疫力,抵抗老年病,瘦命就会延长。
科学家还对限食延寿进行了研究。40 年代马凯伊曾用雄大鼠 作过一系列实验,证明限食可以延长哺乳动物的寿命,并在不同 种类及品系的动物实验中得以证实,限食延寿的机理尚在研究中。 虽然限食延寿已属公认,但还未较普遍地应用于人类。对于限食 研究可以使人们清楚地认识和理解与延寿有关的生物学变化,并
可为完善人类饮食提供有价值的线索。
