前列腺素Ｅ２（ＰＧＥ２）是一种重要的免疫抑制剂，已有实验发现创伤后巨噬细胞释放大量ＰＧＥ２，介导创伤免疫抑制过程［１］，但创伤合并感染后ＰＧＥ２的变化未见报道。本实验观察大鼠创伤及创伤感染早期巨噬细胞分泌ＰＧＥ２能力的变化，探讨其与创伤感染的关系。材... Prostaglandin E2 (PGE2) is an important immunosuppressive agent. It has been found in experiment that PGE2 is released by traumatic macrophages and mediates the immunosuppressive process of trauma [1]. However, the changes of PGE2 after wound infection have not been reported. In this experiment, we observed the ability of PGE2 secreted by macrophages in the early stage of trauma and wound infection in rats, and explored its relationship with wound infection. material...
