在观察原生动物——变形虫时,所感到最烦心的是观察者还没有来得及找着或看清变形虫的形态和运动,水液装片就已将干尽了。尤其是初学的人还想描绘一个真实的图形,那就更觉得困难了。因此,必须设法改进培养和装片的方法,以期解决上述的问题。用半固体培养液垂滴装片观察变形虫的形态和运动,效果很好。这种培养观察片的制作方法很简单,介绍如下: 材料:1.变形虫纯培养液——用稻草浸液培养即可。 2.半固体培养液。适当浓度的稻草水——第500c.c.水加2—3克稻草水,煑沸半小时,浸半小时。半固体的程度——每100c.c.稻草水加0.2克洋
When looking at the protozoa - the amoeba, what you feel most troublesome is that the observer has not yet had time to find or see the amoeba’s form and movement, and the water has just dried up. Especially beginner people still want to describe a real figure, then even more difficult. Therefore, ways must be found to improve training and filming in order to solve the above problems. Using semi-solid culture liquid droplet loading film observation amoeba morphology and movement, the effect is very good. The production of this observation film is very simple to create, described as follows: Materials: 1. Amoeba pure culture - with straw immersion culture can be. 2. Semi-solid culture medium. Appropriate concentration of straw water - No. 500c.c. Add 2-3 grams of straw water, boil for half an hour, soak for half an hour. The degree of semi-solid - per 100c.c. Straw water plus 0.2 grams of foreign
