epidermal-growth-factor and Jaundice--Obstructive

To study the effect of the recombined human growth hormone(rhGH) on secretory immunoglobulin A (sIgA), epidermal growth factor (EGF) in rats with obstructive jaundice.. Sixty Wistar rats were randomly divided into four groups, sham-operated (group A), common biliary duct-ligated (group B), biliary duct-ligated plus rhGH-treat for one week (group C), biliary duct-ligated plus rhGH-treat for two weeks (group D), each group had 15 rats. Except group A, the rats of other groups were operated with biliary duct-ligated. Until two weeks after operation, the rats of group A and B were killed. After operation, the rats of group C were treated with rhGH hypodermic injection (0.75 U x kg(-1) x d(-1)) for one week, and then killed. The rats of D group were treated with rhGH hypodermic injection (0.75 U x kg(-1) x d(-1)) for two weeks, and then killed. All procedures were performed aseptically. Total bilirubin (TB), alkaline phosphatase (ALP), prealbumin(PA), insulin-like growth factor (IGF-1), sIgA, EGF were measured.. Compared with group A, in group B, C, D, serum level of PA, IGF-1 and sIgA, EGF level of gastric and intestinal juice were lower, but TB, ALP were higher, there were significant difference. Compared with group B, the rats with treatment of rhGH in group C and D had higher sIgA and EGF and lower intestinal bacterial translocation.. In objective jaundice rats, rhGH can protect their hepatic function, intestinal physical-barrier function and immune-barrier function, and reduce intestinal bacterial translocation.
