不久前人们还认为细菌感染引起的一系列临床表现是由细菌本身或其代谢产物直接引起的。目前已明确这一系列变化是由于感染及炎症时机体受激活巨噬细胞、淋巴细胞以及其它一些细胞产生的多肽产物,统称细胞素所引起,TNF是其中关键性的一种介质。作者采用22～34kg杂种犬进行研究,实验共分4组:A组(12只)静滴生理盐水;B组(4只);6小时持续静滴TNF;C组(7只);两周前行脾切除术,实验时静滴TNF;D组(8只);
Not long ago, people also believe that a series of clinical manifestations caused by bacterial infection is caused directly by the bacteria themselves or their metabolites. It has been clear that this series of changes is due to infection and inflammation of the body activated by macrophages, lymphocytes and other cells produce peptide products, collectively referred to as cytokines, TNF is one of the key medium. The study was conducted in 22 ~ 34 kg mongrel dogs. The experiment was divided into 4 groups: group A (12 rats) with intravenous infusion of saline; group B (4 rats); continuous intravenous infusion of TNF for 6 hours; group C Splenectomy, experimental intravenous infusion of TNF; D group (8);
