摘要
用分光光度计对缺血心肌切片琥珀酸脱氢酶组织化学反应强度进行光密度定量观察。结果显示，缺血１５ｍｉｎ后，酶活性即明显降低，提高了单纯形态学诊断的敏感性。
The optical density measurement of the succinate dehydrogenase histochemical staining sections of ischemic myocardium with 680 nm of spectrophotometer was made. The result indicated that if the duration of ischemia was more than 15 min,the enzymatic activity showed prominent decrease.This method raised definitely the diagnostic sensitivity for succinate dehydrogenase activity as compared with the mere morphological method.
