研究伴糖尿病的脑梗死患者脑血流量。方法随机选择４１例单纯脑梗死、４４例伴高血压病的脑梗死、３８例伴糖尿病脑梗死、４２例伴糖尿病和高血压病的脑梗死患者，以１３３Ｘｅ吸入法测定脑血流量，并在恢复期复查。结果另３种类型脑梗死患者脑血流量下降均较单纯脑梗死明显，Ｐ＜０．０５～０．０１；巨以伴糖尿病和高血压病的脑梗死患者尤明显，与其他类型比较，Ｐ＜０．０１；恢复期单纯脑梗死患者脑血流量与正常对照组相似，而其他类型脑梗死虽改善，但仍低于正常对照组，Ｐ＜００５～０．０１，且以伴糖尿病和高血压病者脑血流量恢复最差。结论糖尿病合并高血压病进一步减少脑梗死患者脑血流量。
Study cerebral blood flow in patients with diabetes mellitus. Methods Thirty-one patients with cerebral infarction, 44 patients with hypertension, 38 patients with diabetes mellitus and 42 patients with diabetes mellitus and hypertension were enrolled in this study. Cerebral blood flow was measured by 133Xe inhalation. Recovery period review. Results The decrease of cerebral blood flow in the other three types of cerebral infarction patients was more obvious than that of simple cerebral infarction (P <0.05 ~ 0.01). Especially in patients with cerebral infarction with diabetes mellitus and hypertension, P <0.01; recovery of cerebral infarction patients with cerebral blood flow was similar to the normal control group, while other types of cerebral infarction improved, but still lower than the normal control group, P <005 ~ 0.01, and with diabetes and high Blood pressure was the worst recovery of cerebral blood flow. Conclusion Diabetes mellitus complicated with hypertension further reduces cerebral blood flow in patients with cerebral infarction.
