Study on Phospholipid Composition of Erythrocyte Membrane in Hypophosphatemic Cows

<正> The phospholipid constituents of the erythrocyte membrane of cows in hypophosophorus were detected with the field cases and the group comparison. The cows were divided into three groups: the hemoglobinuria group (HN), the hypophosphatemia group (HP) and the control group (CK). The content of the phospholipid constituent in HN and HP obviously changed: phosphatidylethaanolamine (PE) content in HN was significantly lower than that in HP and CK; but sphingomyline (SM) and phosphatidycholine (PC) + phosphatidylserine (PS) content in HN were significantly higher than that in the two other groups; in comparison between HP and CK, PC + PS content was lower and SM content was higher in HP; significant positive correlation and negative correlation were observed between serum phosphorus and PE content, serum phosphorus and SM content respectively.
