我们测量了脑梗塞患者急性期、恢复期、正常人白天清醒状态及夜间睡眠状态尿去甲肾上腺素(NE)分泌率以探讨尿NE24小时分泌节律与脑梗塞发生的24小时时间节律性的关系。 1 材料和方法 1.1对象脑梗塞急性期(病程≤20天)患者21例,男性13例,女性8例,平均年龄61±9岁,为1993年1月至3月住院病人,均经CT证实诊断,肾功能正常,排除嗜铬细胞瘤可能性。恢复期(病程21～31天)13例, We measured the rate of urinary NE release in patients with acute cerebral infarction during acute phase, convalescence, normal daytime awake, and nocturnal sleep state to investigate the relationship between 24 h urinary NE secretion and rhythm of cerebral infarction . 1 Materials and Methods 1.1 Object 21 cases of acute cerebral infarction (duration ≤ 20 days) in 21 patients, 13 males and 8 females, mean age 61 ± 9 years, January 1993 to March hospitalized patients were confirmed by CT Diagnosis, normal renal function, rule out the possibility of pheochromocytoma. Recovery period (duration 21 ~ 31 days) in 13 cases,
