雌性Fisher 344大鼠照射2450MHz微波(10、20和40mW/cm~2;SAR=3.4、6.8和13.6mW/g)两周,每周5天,每天3小时。带植入乳腺腺癌R-3230 AC动物,照射后脾脏有核细胞密度和血清IgG含量与照射功率密度呈负的剂量—效应关系;外周血非PHA刺激的淋巴细胞转化与功率密度呈正的剂量—效应关系。非带肿瘤动物无上述剂量—效应关系出现。说明带肿瘤动物的免疫系统对微波照射反应的敏感性高于非带肿瘤动物,前者的细胞和体液免疫反应均出现变化,意义有待查明。
Female Fisher 344 rats were irradiated with 2450 MHz microwaves (10, 20 and 40 mW / cm ~ 2; SAR = 3.4, 6.8 and 13.6 mW / g) for two weeks, 5 days a week for 3 hours a day. In R-3230 AC mice with implanted breast adenocarcinoma, the density of splenic nucleated cells and the serum IgG level showed a negative dose-response relationship with the irradiation power density. The non-PHA-stimulated lymphocyte transformation and power density in peripheral blood showed a positive dose - the relationship between effects. Non-tumor-bearing animals did not have the above dose-response relationship. The results show that the immune system of tumor-bearing animals is more sensitive to microwave irradiation than non-tumor-bearing animals, and the former cells and humoral immune responses all change.
