摘要: 应用带过滤罩的透明鼠笔在层流柜内繁育T和B淋巴细胞缺失的重度联合免疫缺陷(scid)小鼠获得成功。1993年5月至1994年4月,共繁育scid小鼠221只,寿命均超过12个月。平均每窝产仔数为5.5只,显著低于对照组BALB/c小鼠;不育率为14.9%,离乳率为88.2%,与BALB/c小鼠相比均无明显差异。scid小鼠4~10周龄的体重与同龄BALB/c小鼠相比也无明显差异,微生物学检测均符合SPF级小鼠标准。剖检发现其胸腺极小,胸腺的相对重量仅为同龄BALB/c,小鼠的6%左右,脾脏相对重量则为2796~37%。外周血淋巴细胞仅占白细胞总数的11%~26%。人癌移植于scid小鼠后获得3种人癌移植瘤:肺腺癌(LAX-83),肝细胞肝癌(LC-412),结肠粘液癌(colon),其平均瘤重均显著大于裸小鼠。

Abstract: Severe combined immunodeficiency (SCID) mice, deficient for both T and B lymphocytes, had been bred successfully in laminar air flow units. The life spans of most SCID mice were over 12 months, the average litter size 5.5, the reproductive and weaning rate were comparable to those of BALB/c mice. The results of microbiological examination showed that the animals were free from the specific pathogens. It was also revealed that the thymus and spleen were significantly smaller than those of BALB/c mice, circulating lymphocytes comprised only a small fraction of the total leukocytes in the peripheral blood (11%-26%)» while neutrophils amounted to 74%—87%. Three kinds of human tumor tissues (lung carcinoma, liver cell carcinoma and mucinous carcinoma of colon) xenografted in SCID mice grew much more faster than those in BALB/c nude mice.
