[Changes of cytokine levels in ascitic fluid after intraperitoneal administration of OK-432 or CDDP].
In order to evaluate the biological response after intraperitoneal administration of OK-432 and CDDP, we studied the changes of cytokine levels in ascitic fluid. A total of 53 gastric cancer patients were included in this study. OK-432 20KE was administered in 7 patients and CDDP was administered in 4 patients intraperitoneally during operation. The IL-6, IL-8, TNF-alpha and sTNF RI levels in ascitic fluid were measured from 0 to 5 postoperative day. These results were compared with those obtained from the control groups (42 patients). The ascitic level of IL-6 increased immediately after operation, then gradually decreased. The elevations of IL-6 from 0 to 5 postoperative day were remarkably higher in the OK-432 treated group, and those on 0 and 1 postoperative days were remarkably lower in CDDP treated group than in the control group. Similarly, the ascitic level of IL-8 elevated soon after operation and then decreased gradually. In the OK-432 treated group, the ascitic level of IL-8 was significantly higher than in the control group from 0 to 2 postoperative day. Ascitic TNF-alpha was detectable only in the ascites soon after operation in the OK-432 treated group. The ascitic level of sTNF RI peaked on 2 postoperative day in the control and the OK-432 treated group and 1 postoperative day in the CDDP treated group. There were no significant differences between these groups.
