《印度教徒报》1981年4月15日报道:澳大利亚的生物学家和老年学家伯尔内特(Macfarlane Burnet)爵士提出,需要研究老年人的智力丧失是否可能由于身体不能从食物中吸收足够的锌所致。他说,制造和修补基因密码分子DNA的酶没有足够的锌是不能发生作用的。如果神经细胞和脑中这种DNA的修补系统破坏,即可能引起老年人的智力丧失,此种情况称作老年性痴呆。 Hindu Newspaper reported on April 15, 1981: Sir Macfarlane Burnet, an Australian biologist and gerontologist, is asking whether it is possible to study whether the intellectual loss of the elderly is likely due to the inability of the body to absorb enough of the food Due to zinc. He said that there is not enough zinc in the enzymes that make and repair the DNA of the genetic code molecules. If the nerve cells and brain DNA repair system damage, which may cause mental loss in the elderly, this situation is called Alzheimer’s.
