摘要: 目的 探讨康莱特注射液(KLT) 对小鼠Lewis 肺癌生长及对表皮生长因子受体(EGFR)蛋白表达的影响。方法 建立小鼠Lew is 肺癌模型, 将40 只接种Lew is 肺癌细胞的C57BL/6 小鼠随机分成4 组:模型对照组、KLT 低剂量组(6 .25 mL/kg) 、KLT 中剂量组(12 .5 mL/kg) 、K LT 高剂量组(25 mL/kg), 每组10 只。小鼠连续腹腔注射KLT 注射液14 d, 于接种后第16 天处死小鼠, 测量瘤重及体重, 计算肿瘤抑制率, 提取肿瘤组织总蛋白, 通过Western blot 法检测肿瘤组织EGFR 的蛋白表达情况。结果 KLT 注射液能明显抑制Lew is 肺癌小鼠肿瘤的生长, 影响肿瘤组织的形态及组织学改变, 并能降低肿瘤组织中EGFR 的蛋白表达量。结论 KLT 注射液可明显抑制小鼠Lew is 肺癌的生长, 其机制可能与抑制EGFR 的蛋白表达有关。

Abstract: AIM: To research the effects of Kanglaite (KLT) injection on anti tumor and expression of epidermal growth factor receptor (EGFR) in Lew is lung carcinoma (LLC). METHODS: A to tal of 40 C57BL/6 mice were randomly divided into four groups, including model group, KLT 6.25, 12.5, 25 mL/kg groups.All the mice were injected with 2 ×106 LLC cells at 1st day.A t the next day, mice in the K LT groups were peritoneally injected with KLT for 14 days.And at the 16th day, all the mice were sacrificed and the tumors were harvested.The tumor weight was measured and the tumor grow th inhibition rate was analyzed.The expression of EGFR was detected by westernblot.RESULTS: The growth of LLC was significant ly inhibited by KLT, the changes of tumor appearance and histology were affected and the expression level of EGFR was decreased.CONCLUSION: KLT injection could obviously inhibit the growth of LLC, whose mechanism maybe related to the inhibition of EGFR expression.

Key words: Kang laite injection, Lung carcinoma, EGFR
