牦牛胎盘活性因子生物学效应的研究

通过在培养基中加入不同浓度的牦牛胎盘粉饲养果蝇,研究牦牛胎盘活性因子对果蝇繁殖力和体重的生物学效应.结果表明:①牦牛胎盘活性因子对提高果蝇的繁殖力有显著作用,当牦牛胎盘粉浓度为0.6%时效果最显著;②牦牛胎盘活性因子对果蝇体重有影响.培养在牦牛胎盘粉浓度为2.4%培养基中的雄果蝇体重与对照组有显著差异,而培养在浓度为0.2%培养基中的雌果蝇体重与浓度为0.6%、1.2%、2.4%培养基中的雌果蝇体重有显著差异.

Study on the biological effect of yak placental live factor

The biological effect of yak placental live factor(YPLF) on the reproductive capacity and body weight of drosophila is studied by adding different concentrations of yak placentin to the cultures used for feeding flies.The results show that: Firstly,YPLF can increase the reproductive capacity of the flies extremely,and at its peak when the concentration is 0.6%;Secondly,YPLF has an effect on the body weight of the flies.There are significant differences in body weight between the male flies fed in the culture contains 2.4% of yak placentin and those of the control group.While there are fairly significant differences in body weight between the female flies fed in the culture contains 0.2% of placentin to those fed in the cultures contain 0.6%,1.2% and 2.4% of yak placentin.
