摘要
The study investigated the effects of Qingguang＇an Ⅱ（a Chinese medicinal preparation） on expressions of OX42 protein and interleukin-1β（IL-1β） mRNA of retinal microglia cells of rats with chronic high intraocular pressure（IOP）. SD rats were randomly divided into 6 groups, that were： A： blank group; B： model group; C： Qingguang＇an Ⅱ low dose group; D： Qingguang＇an Ⅱ medium dose group; E： Qingguang＇an Ⅱ high dose group; F： Yimaikang disket（a Chinese medicinal preparation） group. Experimental rats in B, C, D, E, F groups were established the model of chronic high IOP by cauterizing of superficial scleral vein. Tissues of eyes were obtained after intragastric administration for 2 and 4 wk. At the time-point of 2 wk, OX42 protein and IL-1β mRNA in group B were statistically expressed in higher level comparing with other groups（P〈0.05）. Moreover, at the time-point of 4 wk, OX42 protein and IL-1β mRNA in groups C, D and E were statistically expressed in lower level comparing with group F（P〈0.05）. Besides, OX42 protein and IL-1β mRNA in groups C and D were statistically expressed in higher level comparing with group E（P〈0.05）. OX42 protein and IL-1β mRNA in groups C and D were expressed in similar level（P〉0.05）. The study indicated that, in the protection of optic nerve of rats with chronic high IOP, the high dose of Qingguang＇an Ⅱ at the time-point of 4 wk was the better choice.
