摘　　要：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(H_2O_2)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 5～100μg/ml could inhibit the release of H_2O_2 from rat PMΦin vitro.The results suggest that these effects could be one of the mechanisms of anti-inflammatory action of CCA.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Ｈ＿２Ｏ＿２释放的影响。经ＣＣＡ（１０．２００μｇ／ｍｌ）作用后所制备的含ＩＬ－１上清液（正常大鼠腹腔巨噬细胞１．５×１０￣７／ｍｌ，ＬＰＳ８μｇ／ｍｌ）使小鼠胸腺细胞在体外增殖活性（［３￣Ｈ］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Ｈ＿２Ｏ＿２释放，可见ＣＣＡ５～１００μｇ／ｍｌ对腹腔巨噬细胞Ｈ＿２Ｏ＿２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。
