顺铂鱼肝油酸钠配伍治疗胃癌的实验研究

EXPERIMENTAL STUDY OF COMBINATION TREATMENT WITH SODIUM MORRHUATE AND CIS-DIAMINOCHLOROPLATINUM FOR HUMAN GASTRIC CANCER

用ＭＴＴ法观察顺铂（ＣＤＤＰ）与鱼肝油酸钠（ＳＭ）配伍对人胃癌细胞ＳＧＣ－７９０１的体外杀伤效果。人胃癌细胞ＳＧＣ－７９０１被接种于裸鼠皮下以建立荷瘤裸鼠。ＣＤ－ＤＰ每次３ｍｇ·ｋｇ－１·ｔｉｍｅ－１，ＳＭ：５０ｍｇ·ｋｇ－１·ｔｉｍｅ－１，容量：５０μｌ，肿瘤组织中心注射。配伍组肿瘤ＳＭ和ＣＤＤＰ交叉给药，两药间隔３０分钟，每３天１次，共３次。ＳＭ在体外对胃癌细胞有很强的杀伤作用；局部注射后，配伍组的抗癌作用明显高干各单一药物组，肿瘤细胞全部坏死，周围有纤维组织包绕，血管内皮细胞坏死。ＳＭ与ＣＤＤＰ协同抗肿瘤作用明显。

The antitumor effect of sodium morrhuate (SM ) and cis - diaminoaichloroplatinum (CDDP ) for gastric cancer cell SGC - 7901 in vitro is observed with MTT assay. Human gastric cancer cells line SGC - 7901 were inoculated subcutaneously in the naked mice , so xenografts were established. The tumor of the mice in the combination groups were cross injected with SM 50mg . kg^(-1) . time^(-1) , 50μl and CDDP ( 3mg · kg^(-1)· time^(-), 50μl)in varying order at an interval of 30 minutes. In each mouse the tumors were injected every third davs for a total of three injections. lt was found SM had strong antitumor effect on gastric can- cer cells in vitro experiment. The antitumor effect of local injection in combination groups were much stronger than that in any other single drug groups. The histopathological section observation showed that all tumors cells were necrotic in combination groups, There could be seen fibrous histocysts around the . necrotic tumor tissue in observation groups , and necrotic vascular endotheliocytes. The experiment showed that combined injection with SM and CDDP had a synergic antitumor effect.
