Effect of 5-dimethyldithiocarbamylpicolinic acid (YP-279), a dopamine beta-hydroxylase inhibitor, on the secretion of pancreatic juice induced by dopamine was investigated in preparations of the isolated blood-perfused canine pancreas. Either a single injection (300 micrograms) or an infusion (100 micrograms/min) of YP-279 intra-arterially (i.a.) caused no change in the outflow of the pancreatic juice, but the secretagogue effect of dopamine (1-10 micrograms, i.a.) was enhanced by the infusion of YP-279 (100 micrograms/min, i.a.) for 60 min. The previous conclusion obtained with fusaric acid was confirmed as follows; the dopamine beta-hydroxylase activity controls the dopaminergic mechanism of the pancreatic secretion.
在离体血液灌注犬胰腺制备物中,研究了多巴胺β-羟化酶抑制剂5-二甲基二硫代氨基甲酰吡啶酸(YP - 279)对多巴胺诱导的胰液分泌的影响。动脉内单次注射(300微克)或输注(100微克/分钟)YP - 279不会引起胰液流出量的变化,但在输注YP - 279(100微克/分钟,动脉内)60分钟后,多巴胺(1 - 10微克,动脉内)的促分泌作用增强。用富马酸获得的先前结论得到如下证实:多巴胺β-羟化酶活性控制胰腺分泌的多巴胺能机制。
