Abstract

A comparison of the lipid content of normal and carrier-erythrocytes from cattle revealed no differences in phosphatidyl ethanolamine, sphingomyelin, phosphatidyl serine, or cholesterol. The ratio of membrane phospholipid to cholesterol and membrane-bound erythrocyte acetyl cholinesterase activity was unchanged. A microcytic tendency was observed for carrier-cells, however, this physical property of the cell cannot be related to measurable differences in lipid content of the cells.

摘要

对牛的正常红细胞和携带(特定物质)红细胞的脂质含量进行比较后发现,磷脂酰乙醇胺、鞘磷脂、磷脂酰丝氨酸或胆固醇方面并无差异。膜磷脂与胆固醇的比例以及膜结合红细胞乙酰胆碱酯酶活性均未改变。不过,观察到携带(特定物质)的细胞有小红细胞倾向,然而,细胞的这种物理特性与细胞脂质含量的可测量差异并无关联。
