Abstract

Inhibitors of dopamine beta hydroxylase (DBH) administered intraperitoneally were shown to prevent spasm of the basilar artery caused by blood application in cats. A low or nondetectable blood DBH activity level may be related to the absence of spasm. In several instances, however, moderate spasm did occur with a low blood DBH activity level. Possible mechanisms for these findings are discussed.

摘要

经腹腔注射的多巴胺β羟化酶(DBH)抑制剂可预防猫因注入血液而引起的基底动脉痉挛。血液中DBH活性水平较低或无法检测到可能与无痉挛现象有关。然而,在一些情况下,血液中DBH活性水平较低时仍会出现中度痉挛。本文讨论了这些发现的可能机制。
