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。

For suspected cases, in early pregnancy (8-12 weeks), chorionicvilluscell karyotype analysis was done in those with spontaneous natural abortion; in the midtrimester (13-24 weeks) and the late pregnancy (over 25 weeks), the abortus or newborn blood was collected for chromosome analysis.

Methods:All of 40 male Sprague-Dawley rats were divided into 3 groups:control group（group A, n = 10）, diabetic group for 4 weeks（group B, n = 14）, and diabetic group for 12 weeks（group C, n = 16）. The diabetes model was established by the injection of STZ. After some weeks erection function was examined by apomorphine injection.

After a two-week screening period, 18 patients participated in a four-week as-required regimen of 2 mg apomorphine SL, escalated to 3 mg when appropriate after two weeks. Three patients (16.7%) benefited from this treatment modality ( P .05). The nonresponding group of 15 patients continued with a daily regimen of 2 mg apomorphine SL for two weeks followed by 3 mg daily for two weeks. The 3 mg daily regimen was more effective for ED ( P .02) and for each sexual domain scored with the International Index of Erectile Function questionnaire. Adverse events, as reported by three patients (23%) during the 3 mg regimen, were nausea, dizziness, and headache.
