【Abstract】 Objective\ To study the changes and the significance of red blood cell membrane sialic acid (RBCm SA) and plasma sialic acid (P SA)in the patients with acute myocardial infarction (AMI).\ Methods\ RBCm SA was determined with bialsche reagent test and P SA was estimated with F 8836 chemical colorimetric method.\ Results\ RBCm SA in the patients with AMI was significantly lower than that in the control group, but P SA in the patient group was significantly higher than that in the normal control group, so there was a striking difference( t=4.41,4.85,P <0.01). Negative correlations were found between RBCm SA and P SA ( r=-0.486,-0.503, P <0.05) in both normal control group and the patients group.\ Conclusion\ The metabolic disturbance of SA happens to the patients with AMI. Detecting RBCm SA and P SA surely has diagnosis value.\;更多还原
