The concentrations of immunoreactive gastrin in serum from portal and peripheral venous blood were determined in 10 patients with indwelling portal catheters before and after feeding. No significant differences were found between the gastrin concentrations in portal and peripheral serum. Gel filtration studies of serum did not reveal any differences between the gastrin components of portal and peripheral venous serum. Since neither the concentrations of immunoreactive gastrin nor the four gastrin components differed between portal and peripheral serum it is suggested that the liver is without effect on gastrin metabolism.
对10例留置门静脉导管的患者在进食前后测定门静脉血和外周静脉血血清中免疫反应性胃泌素的浓度。门静脉血清和外周血清中的胃泌素浓度未发现显著差异。血清的凝胶过滤研究未显示门静脉血清和外周静脉血清的胃泌素成分之间有任何差异。由于门静脉血清和外周血清中的免疫反应性胃泌素浓度及四种胃泌素成分均无差异,提示肝脏对胃泌素代谢无影响。
