The developmental pattern of seminiferous tubules and the appearance time of various spermatogenic ceils in grafts were similar as seen in intact mice.

移植物中生精小管的发育及各阶段生精细胞出现时间与在正常小鼠中所见基本相同。

The testis contain great number of seminiferous tubules. The epithlium of the tubule produce different stages of spermatogenic cells.

精巢呈多小管构造，有许多生精小管，生精小管不断增殖，产生了不同发育阶段的雄性生殖细胞。

Histological analysis was performed for the observation of the structure of seminiferous epithelium and the composition of spermatogenic cells in grafts.

将出生1.2d昆明小鼠睾丸移植到7—12周去势雄性免疫缺陷小鼠背部；在移植后不同时间段（分为3d、1—11周和3.6月16个组）取出移植物，计算移植物的回收率，测定移植物重量，观察移植物中生精小管结构及生精细胞的组成。

The patient with seminoma was treated with surgery and radiation, while those with nonseminoma tumors were treated with chemotherapy and/or surgery.

精细胞瘤的病患以手术加上放射线治疗；而其他的非精细胞瘤病患则以化学治疗加上开刀治疗为主。

TGCTs are histologically classified into seminoma and non-seminoma, or combination of the two types.

依据组织型态可将睪丸生殖细胞肿瘤区分为两大类：精细胞癌类与非精细胞癌类。

The Wilcoxon signed rank test was applied for comparison of sperm quality.. RESULTS: In total, 67 varicocelectomies were performed. Of the patients, 37(66.1%) were adults and 19(33%) were adolescents. In 36 infertile patients (64.3% of 57 patients), 8 had bilateral varicoceles. Oligospermial was noted in 8 of the 36 infertile patients (22.2%), 19 (52.8%) had asthenospermia, and 9 (25%) had oligoasthenospermia.

结果：在总计上，我们完成了六十七个显微外科精索静脉切除手术，在这些病人中，有三十七个（66.1%）是成年人和十九个（33.9%）是青春期的患者，在三十六个（占五十六个患者的643.3%）的不孕病人中，有8个患者有双边精索静脉曲张，在这三十六个不孕病人中有八个病人（22.2%）是oligospermia，十九个（52.8%）是 asthenospermia，和九个（25%）是oligoasthenospermia。

In addition, the silica-precipitating and templating roles of protamine were elucidated, and the mediation mechanism of organic molecules in biomimetic silicification was also tentatively analyzed.

最终确定以羧甲基纤维素钠为仿生微囊的液核，制备出具有海藻酸/精蛋白壳膜和精蛋白/氧化硅杂化壳壁的微囊，并用于包埋GUS，催化黄芩苷转化为黄芩素。

The main purpose is how to choose proper refining slag in accordance to different steel grade.

根据不同的钢种选择合适的精炼渣成为目前研究精炼渣的主要目的。

The results show:(1) In testis, PNA receptors sites were firstly observed in the cytoplasm and plasma membrane of primary spermatocyte, and greatly increased in the plasma membrane of second spermatocyte, then decreased and were accumulated in the tail of the round spermatid. The same reaction was observed in sperms of testis and spermatheca, which shows stronger reaction in head and weaker in tail. A universal dyeing was observed on the plasma membrane of sertoli cells.

结果表明：(1)在中华蚱蜢的精子发生中，PNA受体是由初级精母细胞合成，然后转移到膜上，在次级精母细胞，由于量的积累其质膜出现了强阳性标记；从早期精子细胞到成熟精子时期糖蛋白的分布发生了明显的修饰变化，这些变化与精子获得与卵子进行识别、粘附、结合等受精能力密切相关：受精囊内与精巢内的精子表面的标记是相同的，说明质膜糖蛋白的修饰作用在精巢内就已完成。

Methods Male infertility couples from October 2006 to July 2008 were chosen and divided into ICSI group and TESA+ICSI group. ICSI group were 584 oligozoospermia cases with alive normal sperm in spermatic fluid. TESA+ICSI group were 54 obstructive azoospermia cases with alive normal sperm in testicle. Two groups were treated with ICSI after wives obtained oocytes by ovarian stimulation.

选择2006年10月～2008年7月因男性不孕症夫妇行ICSI治疗的患者638例分成两组，ICSI组和TESA+ICSI组，ICSI组为自行排精后精液内可以找到正常形态活精子的少精症患者行ICSI治疗584例，TESA+ICSI组为梗阻性无精子症患者经睾丸穿刺找到睾丸内形态正常活精子行ICSI治疗共54例，两组女方均给予超促排卵用药获取卵母细胞。
