睾丸激素

The International Olympic Committee told Greek officials on Friday that Leonidas Sampanis, a weight-lifter who won the bronze medal in the Athens games, has shown abnormally high testosterone levels in doping test.

周五国际奥委会向希腊官员表示，希腊举重运动员桑帕尼斯在药检中睾丸激素呈阳性。此前桑帕尼斯在奥运会首日的举重比赛中获得一枚铜牌。

Of the 32 cases,26 underwent bilateral orchiectomy before radiotherapy, l case received emasculation by radiotherapy and 5 cases by luteinizing hormone-releasing hormone agonist.

内分泌治疗采用去势加抗雄激素治疗的联合雄激素阻断治疗，26例放射治疗前接受双侧睾丸切除，1例行睾丸放疗去势，5例应用抑那通药物去势。

But a piece of research just published in the Proceedings of the National Academy of Sciences by Paola Sapienza of Northwestern University, near Chicago, suggests an alternative—that it is not a person's sex, per se, that is the basis for discrimination, but the level of his or her testosterone.

但是靠近芝加哥的西北大学圣保罗分校最近在国家科学院的报告中发布的一些研究让人们对此看法有所改变——人们对一个人的性别并不是基于偏见，而是取决于他睾丸激素分泌的程度。

Leptin levels paralleled changes in testosterone,with high levels in infancy, a prepubertal nadir, then elevationthrough puberty.

瘦素水平与睾丸激素平行变化，婴儿期较高，青春期前期到最低点，然后整个青春期不断上升。

Many American women already use testosterone treatments off-label to treat their low libidos, and doctors attest that they work.

许多美国女性已经利用睾丸激素来摘掉扣在她们身上&性欲缺乏&的帽子，医生证明这种方法行之有效。

Factor into this equation that men's skin is oilier, due to testosterone – thus they age less quickly – and it begs the question whether chaps need skincare at all.

考虑到由于睾丸激素的缘故，男性的皮肤更油，这就让我们可以想当然地认为，关于小伙子们是否需要护肤品的问题，答案是肯定的了。

Once these testosterone pellets dissolve your system will be back to normal.

A couple remarked that the board discussion was a bit politer and that any tendency towards testosterone-fuelled aggression was slightly tempered.

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。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
