肝脏与其他器官一样,在机体衰老时,其形态与功能发生变化,衰老细胞的变化,亦与其他细胞的变化相似。一、肝脏的老年性变化首先肝脏的变化是重量减轻,Callo-way在尸检400个肝脏,发现肝的重量在30—40岁平均1926克,90—100岁1000克,以60—70岁下降最明显,60—70岁以前肝占体重的2.5%,90～100岁为1.6%。其原因是肝实质细胞的数目减少,再生能力减退。30例健康老年人肝活检的结果,发现核仁增
Like other organs, the liver changes its morphology and function as the body ages. The changes of senescent cells are also similar to those of other cells. First, the liver changes in the elderly The first change in the liver is weight loss, Callo-way autopsy in 400 liver and found that the weight of the liver in 30-40 years old average 1926 grams, 90-100 years old 1000 grams to 60-70 years of decline Most obviously, the liver, which is 60-70 years old, accounts for 2.5% of the body weight and 1.6% from 90 to 100 years of age. The reason is that the number of hepatic parenchymal cells is reduced and the regenerative capacity is diminished. 30 cases of healthy elderly liver biopsy results, found that the nucleolus
