益肾颗粒可以延长小鼠游泳时间；增加在同一寒冷条件下，相同时间内小鼠的存活数；对免疫力低下小鼠，给药组动物的碳粒廓清指数增大，反映吞噬功能增强；在血清溶血素含量测定试验中，给药组动物的上清液吸收值增大，说明机体产生的抗体较多。

Methods (1) The influence on the rats with non-bacterial prostatitis of 1.5% carrageenin. Rats were divided randomly into the normal control group, the model control group, the Qianliean low-dose group (1.5 g/kg), mid-dose group (3.0 g/kg), high-dose group (6.0 g/kg), with 10 rats in each group. All groups were treated continuously for 7 days, once a day. The model control group was given distilled water, 30mins after the last medication, injects 1.5% carrageenin 0.05ml in each rat's prostate, after 24hs, behead execute the rats and record the white blood cell number and Lecithin density.(2) the influence on the swelling ears of rats.
