The nuclear protein encoded by N gene is consist of 422 AA residues (47kDa), Each virion contains 1258 copies that can effectively protect viral RNA from being digested by nucleotidase. The N protein presents a group specificity, it exists in various types and subtypes of VS and plays a very important role in transcript copy. Due to its characteristics of high antigenicity, the N protein can stimulate the body producing nonneutralized antibody.

The results showed that (1) COX-2 mRNA and protein existed in the mature male rat testis. COX-2 was localized in spermatocytes by immunohistochemistry.(2) COX-2 also existed in adult man testis. COX-2 protein was positively stained in spermatocytes and Leydig cells.(3) 2 weeks after administration of rofecoxib, the level of testosterone in the whole testis reached its lower values, being only 50% of control values. However, testosterone level recovered during 4 weeks. After such treatment, histologic examination of these testes showed atrophy of the seminiferous tubules and maturation arrest of spermatogenesis.(4) 2 weeks post-EDS, expression of COX-2 decreased significantly (P.005), in comparison with vehicle-treatment control. 4 weeks after treatment, a new generation of fetal like Leydig cells repopulated in the testicular interstitium resulting in COX-2 expression partially recovered. Although the expression of COX-2 mRNA and protein are enhanced at 8th week after using external testosterone, it wasn't significant higher than control group.

实验研究证明：(1)正常成年雄性大鼠睾丸组织中COX-2在mRNA和蛋白质水平均存在表达，免疫组织化学结果显示COX-2定位于曲细精管内的生精细胞；正常成年男性睾丸组织中同样存在COX-2表达，免疫组织化学结果显示COX-2定位于曲细精管内的生精细胞和Leydig细胞；(2)服用特异性COX-2酶抑制剂rofecoxib 2周后，实验组大鼠睾丸组织内睾酮的含量减少，为正常对照组的50％；持续用药4周后睾丸组织内睾酮浓度逐渐恢复至正常水平；COX-2酶活性降低后病理组织切片显示睾丸内曲细精管萎缩，生精紊乱，持续用药4周时影响最明显；(3)注射特异性Leydig细胞杀灭剂EDS 2周后，实验组大鼠睾丸组织内睾酮浓度降至极低水平时，COX-2的蛋白和基因表达水平也显著低于正常空白对照组（P.005）；使用EDS后第4周，睾丸组织中的睾酮浓度逐渐回升，同样组织中COX-2蛋白表达和mRNA表达水平也相应提高接近正常水平；使用EDS后4周开始给予外源性睾酮，6周和8周时COX-2表达水平的绝对值虽有提高，但与正常大鼠空白对照组比较并无显著性差异，说明外源性雄激素刺激睾丸合成COX-2的作用并不明显。
