Abstract

Isolated nerve endings (synaptosomes) that show high rates of metabolic activity have been prepared up to 24 h postmortem from the brains of patients who have died suddenly. In contrast, similar preparations from brains of patients dying after a prolonged terminal illness showed little or no respiration. These data suggest that the agonal state of the patient is of major importance when investigating specific defects in neurotransmitter function in cerebral disorders and effects of neuroactive drugs on human tissue.

Agonal状态影响死后人脑分离的神经末梢的代谢活动。
从突然死亡的病人的大脑中提取的分离的神经末梢(突触体)在死后24小时内就显示出高的代谢活性。相比之下,从长期身患绝症的病人的大脑中提取的类似制剂显示出很少或没有呼吸。这些数据表明,当研究大脑疾病中神经递质功能的特定缺陷和神经活性药物对人体组织的影响时,患者的非侧方状态是非常重要的。
