乳用种公牛评定方法的比较研究
1
作者 张良银 胡士明 陈宏权 《安徽农学院学报》 CSCD 1990年第3期209-212,共4页
通过对乳用种公牛常用评定方法的比较研究,揭示了不同评定方法的相关性和特点。结果表明:在我国牧场计算机应用不太广泛情况下,可使用女儿均值比较法和同期同龄法进行后裔测定。

本文以南京市12头乳用种公牛(其中引进上海市6头、合肥市1头的冻精)为实例,应用公牛间有亲缘关系的BLUP法估计其育种值,电算求得参数(μ、h_i、g_i、S_(jk)),按育种值排列优劣名次,并与不加入公牛间亲缘关系的结果进行比较,发现两法间... 本文以南京市12头乳用种公牛(其中引进上海市6头、合肥市1头的冻精)为实例,应用公牛间有亲缘关系的BLUP法估计其育种值,电算求得参数(μ、h_i、g_i、S_(jk)),按育种值排列优劣名次,并与不加入公牛间亲缘关系的结果进行比较,发现两法间略有差异,其计算方法在矩阵对角线的公牛效应元素上加A^(1-)(即公牛间亲缘关系的逆阵)即可。研究结果认为在公牛间有亲缘关系时,以加入计算更为符合客观实际,可提高估计精确度。 展开更多

OBJECTIVE: To investigate the preventing and treating action of Liuweidihuang pill(LP) and Jinkuishenqi pill(JP) on spontaneous breast carcinoma in mice.METHODS: A model of spontaneous breast carcinoma was derived from 11.5-month-old female Kunming breeding mice following the delivery of several litters. The mice were randomly divided into five groups: model control group(C),Liuweidihuang pill high-dose group(LH; 4.6 g·kg1·d1),Liuweidihuang pill low-dose group(LL;2.3 g·kg1·d﹣1),Jinkuishenqi pill high-dose group(JH; 4.6 g·kg﹣1·d1) and Jinkuishenqi pill low-dose group(JL;2.3 g·kg﹣1·d﹣1). Cancer tissue volume was measured by water immersion. Histopathology was analyzed by hematoxylin and eosin staining. Vascular endothelial growth factor(VEGF),extracellular signal-regulated kinase(ERK) and cyclin D1 protein expression in cancer tissue was assayed by western blotting.RESULTS: Compared with the control group,cancer tissue volume and weight were lower in the LP and JP groups,and survival time was longer. The expression of VEGF,ERK and Cyclin D1 were inhibited in the LP and JP groups(P < 0.05),and cell differentiation was increased. Tumor weights and volumes and VEGF,ERK and Cyclin D1 expression in LL or LH were significantly lower than in JL and JH(P < 0.01).CONCLUSION: Both LP and JP could restrain cancer growth and promote cancer cell differentiation;moreover,LP was more effective than JP The likely mechanism of action was via inhibition of VEGF,ERK and cyclin D1. 展开更多
