Abstract

The metabolism of the third component of complement (C3) has been investigated in four patients with ulcerative colitis, three patients with Crohn's disease and seven control subjects, using radioiodinated C3 prepared from fresh human plasma. Both the fractional catabolic rate and synthesis rate of C3 were increased in the patients with inflammatory bowel disease, although the serum-C3 levels were normal or raised. The results suggest that complement activation may play a role in the pathogenesis of mucosal inflammation in these diseases.

摘要

利用从新鲜人血浆制备的放射性碘化补体3(C3),对4例溃疡性结肠炎患者、3例克罗恩病患者及7名对照者的补体第三成分(C3)代谢情况进行了研究。尽管炎症性肠病患者的血清C3水平正常或升高,但他们的C3分解代谢率和合成率均有所增加。结果表明,补体激活可能在这些疾病的黏膜炎症发病机制中起作用。
