【摘要】 目的:探讨腹腔内注射沙培林增强人腹腔抗癌免疫功能的机制。方法:72例早中期胃肠道肿瘤患者术前48和24小时腹腔内分别注射生理盐水和5KE的沙培林,术中采集腹腔内巨噬细胞,计数并测定乳酸脱氢酶(LDH)和酸性磷酸酶(ACP)的活性、巨噬细胞吞噬活力、一氧化氮(NO)的分泌以及对人胃癌MKN1细胞的细胞毒性进行分析。同时采集大网膜,对大网膜乳斑的数量和面积进行观察分析。结果:沙培林显著增加腹腔巨噬细胞(PMφ)的数量和NO的分泌,增强LDH和ACP的活性、吞噬活力以及抗癌细胞毒性,也显著增加了大网膜乳斑的数量和面积。结论:腹腔内注射沙培林可显著增加人大网膜乳斑的数量和面积,并因此增加PMφ的数量,增强PMφ的活性。因而增强了腹腔巨噬细胞的免疫功能。更多还原

【Abstract】 Objective:To investigate the mechanism for intraperitoneal injection of sapylin to enhance the anti-tumoral immune functions of peritoneal macrophages.Methods:72 cases of patients with early or middle stage gastrointestinal cancer were peritoneally injected saline or sapylin, 48 h or 24 h before operation. The peritoneal macrophages(PMφ) was harvested during their operations. The number of the PMφ was counted. The phagocytosis, the enzyme activity of LDH and ACP,and the NO secretion were analyzed. Using human gastric cancer cell line MKN1 as target cells, the anti-tumoral cytotoxicity of the PMφ was observed.The greater omentum was harvested,both the number and the size of the omental milky spots were measured.Results:I.p. injection of sapylin significantly increased the number, the phagocytosis, the enzyme activities,NO secretion and anti-tumoral cytotoxicity of the PMφ, as well as the number and the size of omental milky spots.Conclusion:By activating omental milky spots, intraperitoneal injection of sapylin increased the number and enhanced the immune function of PMφ, the activated PMφ showed enhancement of anti-tumoral cytotoxicity.更多还原
