摘　　要：本实验首先通过控制饲料蛋白质的供给量，观察不同蛋白质水平对小鼠嗜盐程度的影响，以探索蛋白质摄入量与嗜盐习性的关系。之后，进一步观察给盐的同时给予高胆固醇高脂肪饲料的小鼠血清总胆固醇（ＴＣ）和甘油三酯（ＴＧ）的水平变化，以探讨血脂代谢与蛋白质摄入量及嗜盐习性的关系。结果表明：低蛋白质（５．２％）饲料使小鼠自发饮用较多的盐水，有可能蛋白质供给量不足是嗜盐原因之一。小鼠摄食高胆固醇高脂肪饲料时，血脂水平明显升高（Ｐ＜０．０５）；同时饮用１．１％食盐水时，血清ＴＣ及ＴＧ水平更显著升高（Ｐ＜０．０１））．ice taking tap water and 1.1%NaCl solution ad libitum were fedwith either 5%or 22%protein diet.Those on 5%protein took more saltwater and less tap water compared to the high protein group.It in dicated that the shortage of protein might be one of the causes of salt thirstyMice fed high fat,high cholesterol die t had higher serum TC and TG thancontrol group(P<0.05),and still higher when 1.1% NaCl solution Wastaken instead of tap water(p<0.01 vs control).The dietary habit wasperhaps closely related to cardiovascular impairment.
