用可移植性乳腺癌(MA-737)瘤株接种36只小鼠,平均分成三组:对照组、LRH-A组和5Fu组,于13天和20天分两批处死。观察瘤组织的生长、组织化学和测量瘤组织重量。观察到LRH-A对瘤组织增重有一定的抑制作用。对照组乳腺癌细胞内AKP、ACP、LDH、SDH和DNA均比其余两组明显增高。说明LRH-A对小鼠乳癌生长有一定抑制作用。 Thirty-six mice were inoculated with a transplantable breast cancer (MA-737) tumor strain and divided equally into three groups: the control group, the LRH-A group and the 5Fu group, and were sacrificed in two batches on day 13 and day 20. Observe tumor tissue growth, histochemistry, and measure tumor tissue weight. It was observed that LRH-A had a certain inhibitory effect on the weight gain of tumor tissues. The AKP, ACP, LDH, SDH and DNA in breast cancer cells in the control group were significantly higher than those in the other two groups. This shows that LRH-A has a certain inhibitory effect on the growth of mouse breast cancer.
