ResultsPe Min Kam Wan, Lam Kam Sang Nasalin and Wo Chun Tong clearly inhibited PCA in mice and reduced histamine release from rat mast cells induced by compound 48/80. But,Sinuwell did not affect the PCA. In addition, the ethanol extracts from Senecio scandens, Selaginella tamariscina and Xanthium sibiricum significantly inhibited PCA in mice, but the extracts from Angelica dahurica, Magnolia liliflora and Cassia tora failed to affect it.

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。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
