Influence of parenteral nutrition via portal vein on insulin and glucagon in liver regeneration / 肠外与肠内营养

ABSTRACT

Objectives:To investigate the influence of PN via portal vein on insulin and glucagon in liver regeneration. Methods:The rabbits were randomly devided into control group( n =5),PN via portal vein group(group Ⅰ, n =10) and PN via central vein group(group Ⅱ, n =10).The PN was performed for 6 days after partial hepatectomy.The concentration of serum insulin and glucagon in portal and perpheral vein were analysed with radioimmunoassay. Results:The concentration of serum insulin was increased in group Ⅰ and group Ⅱ,and it was increased significantly( P 0.05),but it was increased significantly in portal vein blood in group Ⅰ( P
