我室继TA 1和TA 2系小鼠之后,又培育出两系近交系小鼠,命名为TA 3和TB 1系小鼠。该两系小鼠的遗传学检测结果表明,纯合度很高。本文报告两系小鼠的自发瘤,供使用单位参考。材料及方法一、动物来源:TA 3系小鼠来源于天津市,1956年始按兄妹(B×S)交配繁殖。采用第83～84代。共580只((?)273,(?)307)。 TB 1系小鼠,以615×TA 3杂交系严格按兄妹交配育成。采用第26～27代。共394只((?)122,(?)272)。二、实验方法:每系小鼠设两组,即未生殖组和生殖组,每组(?)(?)兼有,分开饲养于塑料盒内,喂给 Following the TA 1 and TA 2 lines, I inbred two inbred strains of mice named TA 3 and TB 1 line mice. The genetic test results of the two lines show that the homozygosity is very high. This article reports two lines of mice spontaneous tumor, for the use of units of reference. Materials and methods First, the origin of the animals: TA 3 mice from Tianjin, 1956 by siblings (B × S) mating breeding. The first 83 to 84 generations. A total of 580 ((?) 273, (?) 307). TB 1 strain mice were bred strictly according to their siblings by 615 × TA 3 hybridization. The first 26 to 27 generations. A total of 394 ((?) 122, (?) 272). Second, the experimental method: Each group of mice set up two groups, that is, no reproductive group and reproductive group, each group (?) (?) Both separately housed in plastic boxes, feeding
