摘要: 为了研究从普通级净化到SPF级前后的KM小鼠免疫功能变化的特点,对同一封闭群的KM小鼠在净化前后分别进行免疫功能的测定。结果KM小鼠净化前后抗体生成细胞分别是557.39±85.77和368.62±65.23;血清抗体水平分别是67.8±26.08和46.4±15.45、碳廓清指数K分别是5.24±0.96和4.61±0.61;碳廓清吞噬指数α分别是0.032±0.023和0.025±0.01;小鼠巨噬细胞吞噬鸡红细胞的指数分别为0.41±0.06和0.36±0.06,吞噬百分数分别为38.42±6.15和31.55±5.75;ConA诱导小鼠脾淋巴细胞转化能力OD值分别为0.032±0.02和0.031±0.01;二硝基氟苯诱导小鼠迟发型变态反应(耳肿胀法)小鼠耳重差分别为10.85±4.34mg和16.29±4.21mg。结果表明,净化后的KM小鼠的巨噬细胞活力、B淋巴细胞活性、抗体水平均小于净化前,有极显著的差异(P<0.01);二硝基氟苯诱导小鼠迟发型变态反应(DHT)大于净化前,有极显著的差异(P<0.01);ConA诱导小鼠脾淋巴细胞转化能力没有变化。

Abstract: In order to observe the changes of immune function in KM mice before and after biocleaning,immunological examinations were conducted. The function of antibody formation cells was 557.39±85.7 and 368. 62±65.23,the antibody level in serum was 67.8±26.08 and 46.4± 15.45,the function of removing carbonaceous granule index K was 5.24 ± 0.96 and 4.61±0.61,a was 0.0032±0.0023 and 0.0025±0.001,the phagocytic function of macrophages in mice’s abdominal cavities 0.41±0.66 and 0.36±0.06,the mice’s lymphocyte transformation induced by ConA (OD value) 0.023±0.02 and 0.031±0.001 ,the mice’s DTH induced by DNFB 10.85±4.34 and 16.29±4.21 before and after biocleaning respectively. It was suggested that some of examined immune function changed significantly after bioclcaning such as the phagocytic activity, B lymphatic cells activity and antibody levels. However, no changes were observed in mice’s lymphocyte transformation induced by ConA.
