摘要: 研究了氯苯扎利钠(CCA)对正常大鼠和佐剂性关节炎大鼠IL-1活性及大鼠腹腔巨噬细胞H2O2释放的影响。经CCA (10~200 μg/mL)作用后所制备的含IL-1上清液(正常大鼠腹腔巨噬细胞1.5×107/mL, LPS 8μg/mL) 使小鼠胸腺细胞在体外增殖活性([3H]TdR参入法)降低。CCA对佐剂性关节炎大鼠ip 7天后可使升高的IL-1活性降低。采用酚红法测定H2O2释放, 可见CCA 5~100 μg/mL对腹腔巨噬细胞H2O2释放抑制作用明显。这些结果表明, CCA抗炎和治疗RA的机制之一可能是通过干扰ROS的释放及抑制IL-1活性, 使IL-1作为肽类炎症介质参与反应和参与免疫调节的过程受阻而达到的。

Abstract: The effects of Lobenzarit disodium (CCA) upon the activity of interleukin-1(IL-1) of peritoneal macrophages (PMΦ) in normal and in adjuvant arthritis AA) rats and on the release of hydrogen peroxide (H2O2) of rat peritoneal macrophages were studied. CCA 10~200 μg/mL could inhibit IL-1activity in normal rat in vitro; CCA 10 and 50 mg/kg could depress the level of increased IL-1 in AA rats in vivo; CCA 5~100 μg/mL could inhibit the release of H2O2 from rat PMΦ in vitro. The results suggest that these effects could be one of the mechanisms of anti-inflammatory action of CCA.
