Abstract

1 Treatment with histamine H2-receptor antagonists, which inhibit basal acid secretion was found to activate rat stomach histidine decarboxylase. At the same time the serum gastrin concentration was greatly increased. 2 In antrectomized rats neither the enzyme activity nor the serum gastrin concentration was affected by the treatment. 3 In analogy with previous observations on other inhibitors of acid secretion we suggest that the H2-receptor antagonists stimulate gastrin release through their effect on acid secretion and that the raised serum gastrin level is responsible for the enzyme activation.

摘要
  1. 人们发现,使用抑制基础酸分泌的组胺H2受体拮抗剂进行治疗会激活大鼠胃组织中的组氨酸脱羧酶。与此同时,血清胃泌素浓度大幅升高。2. 在切除胃窦的大鼠中,该治疗对酶活性和血清胃泌素浓度均无影响。3. 与先前对其他酸分泌抑制剂的观察结果类似,我们认为H2受体拮抗剂通过其对酸分泌的作用刺激胃泌素释放,而升高的血清胃泌素水平是酶激活的原因。
