本文观察药物对果蝇生殖能力的影响,发现一定数目的果蝇在限定时期内产生子代的能力相对恒定,而且受药物的影响较为明显。因此,笔者认为果蝇生殖力可以作为抗衰老药物研究的客观指标之一。材料与方法一、果蝇培养基的配制称取10g玉米粉、13.5g赤砂糖倒入150ml烧杯中加水约40ml,搅匀后加热调成糊状。将琼脂1.5g用10ml自来水加热溶化倒入糊中,同时加入苯甲酸钠0.15g(以3ml50％乙醇预溶)和干酵母粉1.4g,调匀后配成100g重量后倒入培养管规格为直径30×130mm,每管倒入饲料约
This article observes the effect of drugs on the reproductive capacity of Drosophila. It was found that a certain number of Drosophila flies have a relatively constant ability to produce offspring within a limited period of time, and the influence of drugs is more obvious. Therefore, the author believes that fruit fly fecundity can be used as one of the objective indicators for the study of anti-aging drugs. Materials and Methods 1. Preparation of Drosophila Medium Weigh 10g corn powder and 13.5g red sugar into a 150ml beaker and add about 40ml of water. Stir well and heat to make a paste. The agar 1.5g with 10ml of tap water heating melt into the paste, while adding sodium benzoate 0.15g (pre-dissolved in 3ml 50% ethanol) and dry yeast powder 1.4g, after mixing and blending into 100g weight into the culture tube size of 30 diameter ×130mm, pour feed into each tube about
