【摘要】 对伤寒内毒素所致兔脑水肿大脑皮髓质、脉络丛分泌上皮及小血管壁的SDH、ICDH、LDH及MAO 活性的变化进行了动态观察,并用图象分析仪对大脑皮质内SAH及LDH活性进行了相对定量测量。发现四种脱氢酶活性均有改变,且皮质内出现多个局灶性酶活性减弱区。更多还原

【Abstract】 The histochemical changes of dehydrogenases including SDH, LDH, ICDH and MAO were studied in the cortex and medulla, the secretory epithelial cells of choroid plexus and the wall of small blood vessels of the rabbit cerebrum with experimental acute brain edema induced by typhoid endotoxin. The relative quantitative analysis of SDH and LDH activity in the cerebral cortex were determined by Image Analyzer QTM-720. Histochemical changes of these four dehydrogenases and focal regions with diminished enzyme activity occurred in the cortex.更多还原
