ИЗМЕНЕНИЕ УТИЛИЗАЦИИ ПЕЧЕНЬЮ ХЦК-8 ПРИ ВВЕДЕНИИ ТРИПСИНА

The effect of intraportal administration of trypsin on the degree of utilization of cholecystokinin short-chain peptide by the liver by the liver was studied in rats according to the degree of its influence on the secretory function of the pancreas. Studies were conducted on 56 rats in 8 series, 7 acute experiments in each series. Conclusions were made: in rats, the liver utilizes short-chain peptide CCK-8. Trypsin, when co-administered with CCK-8 in the peripheral vein, slightly increases the secretory activity of the pancreas and significantly when administered into the portal vein, which indicates that trypsin can reduce the ability of the liver to utilize the CCK-8 short chain peptide. This fact confirms the involvement of the liver in the change in utilization of short-chain peptides, which is one of the mechanisms regulating pancreatic secretory activity. Trypsin is also involved in these mechanisms of regulation of the activity of the digestive glands, which is new evidence of the existence of a physiological mechanism of the relationship between the gastrointestinal tract and the liver
