为探讨光敏效应对肿瘤组织杀伤机制,我们对小鼠S_(180)肉瘤及C_(57)小鼠肺癌,经用血卟啉—激光作用产生光敏效应后观察肿瘤内微循环形态改变,初步总结如下:材料及方法(一)实验动物选择及分组:本组实验两种肿瘤即S_(180)肉瘤及鼠肺癌。前者选用上海纯系小白鼠24只,体重18～22g,雄性,分为四组即空白对照组,单独激光组,单用血卟啉组,光敏组每组6只,同一条件下分别饲养。后者选C_(57)黑毛鼠24只,体重16
In order to investigate the mechanism of photosensitizing effects on tumor tissue destruction, we observed the microcirculation morphology of tumors in mice with S_(180) sarcoma and C_(57) mouse lung cancer after photosensitizing with hematoporphyrin-laser irradiation. They are as follows: Materials and Methods (I) Selection and grouping of experimental animals: The two types of tumors in this group were S_(180) sarcoma and murine lung cancer. The former selected 24 pure white mice of Shanghai, weighing 18-22g, male, divided into four groups: blank control group, laser alone group, blood porphyrin group alone, and photosensitive group, 6 in each group, under the same conditions, respectively. The latter selected C_(57) black hairs 24, weighing 16
