Successful heterotransplantation of human cell line (SHG-44) to nude mice (NC nu/nu) is reported. The experiments were made on 5~8 wk-old nude mice of both sexes, which were raised from an independent breeding colony in our own laboratory under SPF environment. The tumors had been passaged up to 22 generations in more than 150 recipient animals. The initial transtability was 64% (7/11), and 100% for all the subsequent serial transplantations. After inoculation of recipient animals, the growth rate showed...

Successful heterotransplantation of human cell line (SHG-44) to nude mice (NC nu/nu) is reported. The experiments were made on 5~8 wk-old nude mice of both sexes, which were raised from an independent breeding colony in our own laboratory under SPF environment. The tumors had been passaged up to 22 generations in more than 150 recipient animals. The initial transtability was 64% (7/11), and 100% for all the subsequent serial transplantations. After inoculation of recipient animals, the growth rate showed that latent period was 1~2 wks, slow growth was in a period of 3~4 wks, and rapid growth was 5~6 wks and the late period until death was 7 wks. As for the survival period, after inoculation of animals, the median life span was 52 days and the average life with its standardized deviation was 54 plus and minus 15.4 days.The transplantable tumors were composed of astrocytes and spindle cells, which succeeded all the glial fibrillary acidic protein features. The biological and morphological characteristics of the transplantable tumors were still conformable to that of human malignant glioma.

本文报告人脑恶性胶质瘤体外细胞系SHG-44对NC系裸小鼠的初代皮下移植成功率为7/11,第2~22代的移植成功率达100%。第11代以后肿瘤生物学特征渐趋稳定,肿瘤接种后1~2周为潜伏期,2~4周为缓慢生长期,4~6周为快速生长期,6周以后进入晚期。宿主存活时间为54±15.4天,中位生存期为52天。经形态分析及PAP免疫组化技术,证实第1~21代移植瘤中均存在GFA蛋白,提示本实验的移植瘤始终保持着恶性胶质瘤的特征。

In order to provide a large scale of laboratory rhesus monkeys which have clear genetic and madical backgrounds, standard food and controlled environment, three breeding systems were carried out in National Laboratory Primate Centre of China, Xishuangbanna, Yunnan during 1984-1988. The study of 628 female breeders indicated that the average annual mortility rate of females was 4.7%, average annual conception rate was 83.2%, average annual reproduction rate was 72.2%. The results showed that, in Harem breeding colony, fertility was affected by female social rank and age. There were not significant difference in reproduction for male/female rate within 1/4-16. The major cause of death was trauma, following by cntcropathies. 56.2% of reproductive growth rate was gained in this colony.

为了提供具有清楚的遗传学和医学背景的实验用恒河猴,在控制营养和环境的条件下,比较了三种不同繁殖方法(后宫式、定期配对式和固定配对式)的生殖率,同时研究了后宫式繁殖群的雌雄数量配比、等级地位及雌猴年龄等因素与生殖率的关系,并提出了能较全面地衡量种群饲养管理水平的“繁殖增长率”的计算方法。五年中共选用628只雌猴进行试验,年均生殖率为72.2%。

The incidence studies of spontaneous neoplasms in 446 mice of breeding colony of NC strain, under the SPF condition,during the six years were made. The mice were observed including 164 homozygous nude mice(♂ ,nu/nu)and 302 heterozygous mice(♀ ,nu/+). The average observation time of each mouse was over 7 months,and every one was examined by detailed anatomy when it has been eliminated,the lesions were diagnosed by pathologic histology and transmission electron microscopy.

对本室六年中饲养于SPF条件下的466只NC系裸鼠繁殖群动物的自发性肿瘤发病情况进行了观察研究,其中纯合子鼠(雄nu/nu)164只,杂合子鼠(雌,un/+)302只。每只动物平均观察时间均达7个月以上,淘汰时均经详细解剖学检查,检出病变者进行病理组织学及透射电镜观察确诊。多数肿瘤病例结合裸鼠间可移植性鉴定.共检出自发性肿瘤7例,发生于纯合子裸鼠5例,杂合子鼠2例。结果表明,在相同饲养环境下,裸鼠(雄,nu/nu)的自发性肿瘤发病率(3.04%)比其同系有胸腺杂合子鼠(雌,nu/+)(0.66%)明显增高(P<0.05),且前者的平均发瘤鼠龄比后者为短,其自发瘤以恶性上皮性肿瘤为主。结果支持了免疫功能缺陷的裸鼠比其同系免疫功能正常鼠有更高的自发性肿瘤的观点。作者还提出了评价裸鼠群体自发性肿瘤发病率的方法.
