摘　　要：目的 :比较不同给药方式的胂酸基乙酸 (ASAC)对H22 肝癌移植瘤在小鼠体内生长的抑制作用。方法 :采用腹腔注射和静脉注射2种给药方式 ,分别在小鼠右腋皮下接种肝癌H22 细胞后 ,随机将其分为5组 ,分别注射生理盐水、环磷酰胺及不同剂量的ASAC ,观察癌细胞株的成瘤率、受试物对H22 肝癌荷瘤小鼠的抑瘤作用及其对小鼠脏器的影响。结果 :与腹腔注射给药方式比较 ,静脉注射给予ASAC高、中、低剂量后均产生显著抑制肿瘤生长作用 ,其抑瘤率分别为46. 59 %、46 .31 %和32 .48 % ;2种给药方式的ASAC低剂量组小鼠脾重指数均有升高 ,但静脉注射给予ASAC高剂量组出现了小鼠中毒死亡。结论 :与腹腔注射给药方式比较 ,ASAC静脉注射给药方式的抑瘤作用更好。OBJECTIVE: To compare inhibition effects of arsenacetylic acid(ASAC) on experimental H22 hepatoma-bearing mice in different forms of administration. METHODS: The mice were divided into 5 groups at random after inoculated with H22 hepatoma into their right axillas hypodermic by intraperitoneal injection(ip) and intravenous injection(iv), and then injected with normal saline,cyclophosphamide and different dosage of ASAC, observe the rate of tumor strain becoming tumor, the inhibition effects of the subjects and the effects of the subjects on mice's viscera. RESULTS: Compared with ip,either high, moderate or low dosage of ASAC by iv did have an obvious inhibitory effect on tumor and the tumor inhibition rates were 46.59%, 46.31% and 32.48% respectively; however, the spleen index in groups that of lower dosage of ASAC by two forms of drug administration were increased; there were death by poisoning in the group that iv with high dosage of ASAC.CONCLUSION: Compared with ip, the administration of ASAC by iv has a better effect on tumor.
