Acetylcholine esterase activity and sialic acid content were estimated in human erythrocytes separated according to their densities and after fragmentation in vitro by heating or a combined hyperosmolaric-mechanical stress. In vivo aged cells showed a disproportional loss of both membrane constituents. Fragmentation of erythrocytes in vitro resulted in a proportional loss of acetylcholine esterase activity and sialic acid. Young cells are more prone to fragmentation by heat than older ones.
对根据密度分离的人体红细胞以及在体外经加热或高渗-机械联合应激破碎后的红细胞，测定了乙酰胆碱酯酶活性和唾液酸含量。体内衰老细胞显示这两种膜成分均不成比例地丢失。红细胞在体外破碎导致乙酰胆碱酯酶活性和唾液酸成比例地丢失。年轻细胞比衰老细胞更易受热破碎。
