为观察红色诺卡菌细胞壁骨架（Nocardiarubracellwallskeleton，N－CWS）的抑癌效应，将N-CWS皮下注射于同系移植膀胱癌小鼠并观察其抑癌效应。结果显示，给予N－CWS的小鼠存活期（23．06±5．39d）比对照组（19．06±2．75d）延长（P＜0．01），存活延长率为21．0％。两组抑癌效应的观察结果显示，低荷瘤组的肿瘤消退率为4／10，而对照组无肿瘤消退，实验组平均瘤重（0．18±0．20g）明显低于对照组（4．71±1．05g），抑瘤率为96．2％（P＜0．01）；高荷瘤组则未观察到肿瘤消退情况，但实验组平均瘤重（3．31±0．93g）低于对照组（4．69±0．65g），抑癌率为29．4％（P＜0．01）。表明N－CWS作为一种免疫促进剂具有明显的抑癌效应。
To observe the anti-cancer effect of Nocardiocyte wall scaffolding (N-CWS), N-CWS was injected subcutaneously into mice with bladder cancer and the anti-cancer effect was observed. The results showed that the survival of mice given N-CWS (23.06 ± 5.39d) was longer than that of the control group (19.06 ± 2.75d) (P <0.01), the survival rate was 21.0% . The anti-cancer effect of the two groups showed that the tumor regression rate was 4/10 in the low-tumor group and no tumor regression in the control group. The average tumor weight (0.18 ± 0.20g) in the experimental group was significantly lower than that in the control group 4.71 ± 1.05g). The tumor inhibition rate was 96.2% (P <0.01). No tumor regression was found in the high-tumor group, but the average tumor weight in the experimental group was 3.31 ± 1.05g. 93g) was lower than the control group (4.69 ± 0.65g), tumor suppression rate was 29.4% (P <0.01). It shows that N-CWS has a significant anti-cancer effect as an immunostimulant.
