作者最近的研究表明,为了证明左旋咪唑在动物体内的免疫增强作用是否亦和剂量有关,以及其抗肿瘤作用是否和其对免疫反应的影响有关,作者作了下列的动物实验,方法:用7,12-二甲基苯并蒽诱发雌鼠发生乳癌后,将鼠分为4组,1组不给左旋咪唑,3组分别给予每天口服左旋咪唑2、4、和8毫克/公斤体重,6个月后将动物杀死,测定脾脏淋巴细胞 In order to demonstrate whether levamisole is also dose-related in vivo and whether its antitumor effect is related to its effect on the immune response, the author’s recent study showed that the following animal experiments were performed: After 12-dimethylbenz [a] anthracene-induced breast cancer was induced in females, the rats were divided into 4 groups, one group was given levamisole, the other 3 groups were given oral levamisole 2,4, and 8 mg / kg body weight, respectively Animals were killed months later and spleen lymphocytes were measured
