The reasons for this are not completely understood. It is postulated that this may have some relation to changes of patients′immune function. This article reported the changes of splenocyte IL-2 production and T Suppressor cell activity in rats with obstructive jaundice. Meanwhile, we also investigated effects of cimetidine on immune function in rats with bile duct ligation. The results show that IL-2 production in obstructive jaundiced rats significantly decreased and T suppressor cell activity markably increased. Cimetidine could remarkably enhance IL-2 production and suppress T Suppressor cell activity. Abmormaility of immune function may be one reason for high susceptibility to infection in patients with obstructive jaundice in perioperative period. Cimetidine, which could clearly improve immune function in rats with obstructive jaundice, might be a valuable agent for strengthening the capacity of fighting infection in patients with obstructive jaundice.展开更多

It was postulated that it may bear some relations to abnormalities of immune function. In this article. 28 cases of obstructive jaundice were selected to investigate alternation of monocyte immune function with the purpose of exploring mechanism of high susceptibility to infection from the perspective of immunology. The results showed that interleukin 1 production by monocytes significantly decreased and prostaglandin E2 increased, HLA-DR expression of monocytes was markably depressed. HLA-DR expression of monocytes was further decreased with recovery slower than non-jaundiced patients after operation. All this may be responsible for high susceptibility to infection in the process of treatment of obstructive jaundice .展开更多

The results show that spontaneous suppressor T cell activity of spleen significantly increased and Interleukin 2 production and DNA synthesis capacity of splenocytes markedly decreased in rats with trauma. Indomethacin could markedly improve immune function , decreased spontancous suppressor T cell activity and prompted Interleukin 2 production and DNA synthesis capacity of splenocytes.展开更多
