1.以 Brown-Pearce 癌接种于563只上海繁殖的非纯系家兎的不同部位,有543只肿瘤成活,成活率为96%。其中眼前房及静脉内接种成活率接近100%,脑内、睾丸内及皮下接种的成活率分别为96%,94%和93%。2.不同部位接种后的动物生存期各有差异。静脉内、睾丸内、皮下及脑内接种的家兎平均生存期间分别为20、28、52和14天。3.在320只尸体解剖的资料中,发现肿瘤转移者占92%,转移的主要部位是肺、肝、肾脏及肠系膜淋巴结。4.接种 Brown-Pearce 癌后发生消退的家兎,对再次接种能产生抵抗;另外,Brown-Peace 癌消退的家兎对成骨肉瘤的再接种以及成骨肉瘤消退的家兎对 Brown-Pearce 癌的再接种,也都能产生一定程度的抵抗力。
1. Inoculated with Brown-Pearce cancer in 563 different strains of the non-pure strains of Shanghai breeding, 543 tumors survived and the survival rate was 96%. Among them, the survival rate of the anterior chamber and the intravenous inoculation was close to 100%, and the survival rates of intracerebral, intratesticular and subcutaneous inoculation were 96%, 94% and 93%, respectively. 2. The survival time of animals inoculated at different sites varies. The average survival time of the in-vitro, intratesticular, subcutaneous and intracerebral inoculations were 20, 28, 52 and 14 days, respectively. 3. In 320 autopsy data, 92% of tumor metastases were found. The main sites of metastasis were lung, liver, kidney and mesenteric lymph nodes. 4.Families that have subsided after Brown-Pearce cancer inoculation, can develop resistance to re-inoculation; in addition, re-inoculation of osteogenic sarcoma and dissipated osteosarcoma in families with Brown-Peace cancer regression, Brown-Peace Cancer re-inoculation can also produce a certain degree of resistance.
