为弄清醋酸是否比酒精更具强力的细胞坏死作用,经皮醋酸注入疗法是否对小肝细胞癌有效,以及对复发是否有效等,作者进行此项研究。在大白鼠肝内注入50μl各种浓度的醋酸溶液或无水酒精,数日后杀死,比较肝坏死部分的平均直径,并对肿瘤在3个以内直径1～3 cm的肝细胞癌58例患者,施行超声波指导下穿刺肿瘤注入15％～50％醋酸的经皮醋酸注入疗法。 To determine whether acetic acid is more potent than alcohol, the authors performed this study if transdermal acetic acid injection therapy is effective for small hepatocellular carcinoma and whether it is effective for recurrence. 50 μl of various concentrations of acetic acid solution or absolute alcohol was injected into the liver of rats and killed several days later. The mean diameter of the hepatic necrosis was compared, and 58 tumors of hepatocellular carcinoma with a diameter of 1 to 3 cm within 3 tumors were compared. Ultrasound-guided acetabular injection of 15% to 50% acetic acid was used for percutaneous injection of acetic acid.
