许多物理因素,如温度、射线、不同频率的光、声以及电磁 场等,都会在一定程度上影响人体的健康长寿,尤其是温度对人 体的影响更为密切
人们发现比较变祖的动物(冷血动物),在低 温条件下寿命较长,因此认为这类动物在低温条件下改变体温, 使代谢变慢,从而延长了寿命,对于体温恒定的哺乳动物,环境 温度与寿命的关系正进行着有关研究,如何找出适当的办法来降 低体温,使新陈代谢变缓慢而延长寿命。另外, 출장마사지 。 출장샵 ,抑制了恶性肿瘤,感染和寄 生虫的生殖所致。也有人认为小剂量照射的延寿倾向似乎是—种
称作“毒物兴奋效应”(Hormesis)的表现。
(三)从化学途径的研究
有的学者在自由基学说的实验中试用一些抗氧化剂,例如琉 基乙胶、乙氧唾、丁化轻基甲笨(BHT)、维生素 E 等,实验表 明后二种都有一定的延寿作用,但对其机理尚有不同的解释。有 人认为抗氧化剂抵消了自由基的损伤,这样有利于保证健康长寿; 有人认为抗氧化剂影响了饮食或同化作用;达到与限食延寿同样 的结果,还有人认为抗氧化剂诱导某些屯的活性从而刺激了一些
导致长寿的反应等等。
国内外不少学者对溶屯体膜稳定剂作用进行了研究。膜学说 认为溶屯体膜稳定性下降会使溶屯体膜内的水解屯超常释放,给 细胞带来严重后果,故需要探求膜的稳定剂。有人试验了 40 种 출장마사지 ,有一定 保护作用。根据衰老渣滓学说的观点,人体细胞的萎缩和死亡主 要是由于代谢产物有害物质积累的结果。据南堆等人的研究报告, 跃鼠与小鼠神经细胞中的脂褐素的蓄积量,随着年龄的增加而增 多,如对这些动物中的老年动物使用氯酷醒,可使其神经细胞中 的脂褐素明显减少。 출장마사지 ,给小鼠使用 氯酷醒,可使雄性小鼠的平均寿命增长 27%,使雌性小鼠的平均 寿命增加了 5.9%。另外,遗传学家们指出,人体极有可能存在 着衰老与死亡基因,若证实了这种设想,就能使用遗传工程的技 术关闭这些基因,或者导入年轻人的基因来置换,不断修复那些
已经衰退的关键性基因,则可延长人的寿命。
