查询词典 critical level

Despite evidence implicating prostaglandins as critical factor in male reproductive functions, little is known about expression and function of COX-2 in the male reproductive system. By using immunohistochemistry, RT-PCR and Western-blot, the content of this research included:(1) The expression and localization of COX-2 in mature rat and human testis were examined.(2) We investigated the changes of spermatogenesis and testosterone levels in testis after by using the COX-2 specific inhibitor-rofecoxib at 2, 4 and 8 weeks.(3) To explore the relationship between the intratesticular level of testosterone and expression of COX-2 by completely destroying the Leydig cells of mature male rats with injection of a single I.

本课题应用免疫组织化学、RT-PCR和Western-blot等方法检测以下内容：(1)在mRNA和蛋白水平检测正常成年男性及大鼠睾丸组织中COX-2的表达及定位情况；(2)实验组大鼠持续给予COX-2酶的特异性抑制剂Rofecoxib，分别于用药后2周、4周和8周检测大鼠的精子生成以及睾丸组织内睾酮浓度的变化；(3)另一组实验大鼠给予特异性Leydig细胞灭活剂EDS，在特定时间内抑制睾丸组织内合成的睾酮，于用药后2周和4周，采用免疫组织化学及RT-PCR方法观察大鼠睾丸组织内睾酮浓度变化对COX-2合成的影响。
