第“64”方于临床試用期间除表现有抑制肿瘤生长外。并有一定的鎮痛和消失作用。本文用“64”方甲煎剂进行了初步的动物实驗研究。 (一) 痛作用: 实驗参考改良的Woolfe及Macdonalod法,以不同途径给药,观察用药前后痛阈的变化。相当于生药5克/公斤的“64”方甲煎剂对小白鼠腹腔注射20分钟痛阈提高达最高点, The “64” side showed inhibition of tumor growth except during clinical trials. And there is a certain degree of analgesia and disappearance. In this paper, a preliminary animal experiment was conducted using “64” Fangjia decoction. (1) Pain effect: In the experiment, reference was made to the modified Woolfe and Macdonalod methods. Different routes of administration were used to observe changes in the pain threshold before and after administration. The “64” square-bottom decoction equivalent to crude drug 5 g/kg raised the highest point of intraperitoneal injection of pain threshold in mice for 20 minutes.
