Serum dopamine-beta-hydroxylase (DBH) activity was measured in 34 patients with acute cerebrovascular disease. The serum level of DBH activity showed its highest value soon after the onset of stroke and then gradually decreased over the next few days. After reaching its lowest level, the DBH activity again showed a slight increase. There was no direct relationship between serum DBH activity and total serum protein, or blood pressure. In 8 of 12 patients, DBH activity in the cerebral venous blood was higher than that in the arterial blood. These results suggest that rapid release of DBH into the circulating blood occurred after stroke, presumably from sympathetic nerve endings in the vessels or organs, including the brain.
对34例急性脑血管病患者测定了血清多巴胺-β-羟化酶（DBH）活性。血清DBH活性水平在卒中发作后很快达到最高值，随后在接下来的几天逐渐下降。在达到最低水平后，DBH活性再次略有升高。血清DBH活性与血清总蛋白或血压之间无直接关系。12例患者中有8例，脑静脉血中的DBH活性高于动脉血中的活性。这些结果提示，卒中后DBH迅速释放入循环血液，推测来自包括脑在内的血管或器官中的交感神经末梢。
