    摘要:

    从体内抑制试验和体外培养巨噬细胞的杀瘤试验对甲鱼组织浆的抑瘤作用进行了研究。体内抑瘤 试验采用组织浆灌胃方式, 计算抑瘤率和生命延长率。体外试验将巨噬细胞与肿瘤细胞共培养, 测定NO 浓度与细胞毒效应。培养上清液中一氧化氮(NO)浓度采用NO 试剂盒检测, 细胞毒效应通过MTT 比色法 检测。用黄嘌呤氧化酶法测定服用鳖组织浆大鼠脑、肝、血中的超氧化物歧化酶(SOD)含量。结果表明, 不 同来源鳖的效果有区别, 野生鳖和仿生养殖鳖2 龄与4 龄对S180小鼠肿瘤生长有明显的抑制作用(P <0. 01), 其抑瘤率分别达70.69%和63.17%, 荷瘤小鼠的生命延长率均显著高于空白对照组(P <0.01), 分别为 40.59%和39 .95 %;1 龄与2 龄温室鳖的抑瘤效果也显著(P <0.05)。不同来源和不同年龄的鳖抑瘤效果 有差异, 野生鳖、仿生鳖和温室鳖组织浆能有效地增强巨噬细胞的细胞毒活性和NO 水平(P <0.05 ~ 0 . 01), 且随年龄增长, 效果增加。说明, 鳖组织浆可活化巨噬细胞, 诱生NO 的产生, 增加杀瘤效应。鳖的 组织浆能提高大鼠脑、肝、血中的SOD 活性, 这种增强机体的抗衰老能力, 随鳖的生活环境而有变化。

    Abstract:

    An experiment was conducted to study the turtle plasmasol on turmor immunization , by feeding the turtle plasmasol to observe the inhibiting turmor trial and using MTT to assay the cytotoxicity of macrophages .The activities of SOD were observed to determine the effect of antiagting .The results showed that wild turtle and biomimetic turtle had shown marked inhibiting effect on S180 tumor growth (P <0 .01). The inhibiting tumor rates were 70 .69 % and 63 .17 % respectively .Significant increase(P <0 .01)was observed at the longevity rate on them, 40 .59 % and 39 .95 % respectively .The intruction of nitric oxide in murtur macrophages and macrophage-mediated cytotoxicity in wild turtle group and biomimetic turtle group were significantly higher than those of control group (P <0 .05 -0 .01).These observations suggest that turtle plasasol could be susceptible macrophage to increase NO production and improve the efficiency of killing tumor cells .Significant increase(P <0 .01 -0 .05)was also observed at the SOD activities between treatments and control , which indicated that turtle plasmasol could increase humoral immunity .
