为探讨婴幼儿肺炎心力衰竭时心肌细胞钙代谢的变化，将３２例研究对象分为四组，肺炎合并心衰前后组，肺炎组和正常组。采用原子吸收分光光度仪测定红细胞内外钙离子浓度。结果显示心衰纠正前组和肺炎组，正常组比较。前者红细胞内钙离子增高（Ｐ＜００１）。血浆钙离子下降（Ｐ＜００５）；而心衰纠正后组的红细胞内钙和血浆钙离子和肺炎组，正常组比较统计学无差异。提示在肺炎心力衰竭的病理过程中心肌细胞存在钙代谢紊乱
To investigate the changes of calcium metabolism in cardiomyocytes of infantile pneumonia with heart failure, 32 subjects were divided into four groups: pneumonia group before and after heart failure, pneumonia group and normal group. Atomic Absorption Spectrophotometer was used to determine the concentration of calcium ion inside and outside erythrocytes. The results showed that heart failure before correction and pneumonia group, normal group comparison. The former intracellular calcium increased (P <0 01). Plasma calcium decreased (P <0 05); and after correction of heart failure group of intracellular calcium and plasma calcium and pneumonia, the normal group was no statistical difference. Tip in the pathological process of heart failure in patients with pneumocardial calcium metabolism disorders
