在研究有关药物与钾代谢关系的动物实验中,有时需用低钾饲料。由于全合成低钾饲料价格昂贵,而且某些成分不易购得,一般实验室常无法制备。我们参照大鼠营养要求及有关饲料的组成,以碎米和鸡蛋为主要成分,制成了简易低钾饲料,适用于一般实验室。实验表明,用此饲料喂养大鼠,20天内即可形成缺钾 In animal studies that examine the relationship between drugs and potassium metabolism, low potassium feeds are sometimes required. Because fully synthetic low-potassium feed is expensive and some ingredients are not readily available, labs are often unable to prepare them. We refer to the nutritional requirements of rats and the composition of the feed to broken rice and eggs as the main ingredient, made of simple low-potassium feed, suitable for general laboratory. Experiments show that rats fed with this feed, potassium deficiency can be formed within 20 days
