The testis index, testis volumes were same as the annual changes of testis mass. The curves of annual variation were all unimodality.2 The spermatogenetic cycle of Myospalax cansus comprises seven stages with significant features: Stage I , from February to April, the testis were at the stage of spermatogonia proliferation. In this period, testis index and the number of spermatogonia began to rise. Other spermatogenic cells had not yet formed; Stage II to III, from March to April, primary spermatocyte meiosis period. The testis index was highest in this stage, and spermatogenic cells were in spermatocyte stage, the primary spermatocyte meiosis generated to secondary spermatocyte; Stage IV, from April to May, spermatocytes continued to split, germ cells appeared in seminiferous tubules; Stage V, in May, sperm formation, spermatids of seminiferous tubules were transformed to spermatozoa, a large number of sperms existed in the lumen; Stage VI, spermatozoa emission period, from May to June, testis index were a significant drop and mature spermatozoa excluded gradually; VII, the testicular activity ceased basically from July to September, November to January of the following year, the spermatogenic activity ceased completely. Therefore, Myospalax cansus are animals of seasonal reproduction, spermatogenesis cycle is discontinuous type.

睾丸系数、体积和重量的年周期变化规律一致,变化曲线呈现单峰型。2甘肃鼢鼠雄性生殖腺的年周期活动由7个特征明显的时期构成:Ⅰ期,2~3月份,精原细胞增殖期,睾丸系数开始上升,精原细胞进行有丝分裂,其他生精细胞尚未形成;3~4月份为Ⅱ~Ⅲ期,初级精母细胞成熟分裂期,睾丸系数达到最大,生精细胞大多处于精母细胞阶段,初级精母细胞减数分裂生成次级精母细胞;Ⅳ期,4~5月份精母细胞继续进行分裂,精细胞在生精小管内出现;Ⅴ期,5月份,精子形成期,曲细精管中精细胞变态成精子,在管腔中存在大量的精子;Ⅵ期,精子排放期,5~6月份,睾丸系数显著下降,成熟精子从生精小管上脱离,逐渐排除;Ⅶ期,精原细胞停滞期,7~9月份睾丸生精活动基本停滞,11~翌年1月,生精活动完全停止。

Objective It was reported that rALR (rat augmenter of liver regeneration) distribute in most of tissue and organ of rat, no-tissue specility; mRNA expression of rALR was identified variedly in different tissue, strongest in testis. But nowadays there was not some study on ALR in rat testis. Here to confirm the expression and localization of ALR in infancy,adult and old rat testis,comparing the change of ALR expression degree before per 70 PH and after per 70 PH. In order to evaluate expression principle of ALR in rat testis and know if ALR has tight connection with spermatogenesis and development of testis, to explore the relation between ALR and reproduction, to discover the possible expression character and functional methods of ALR.

目的:文献报道rALR分布于各组织器官,无组织特异性,但其mRNA在各组织的表达强度有差异,在睾丸组织表达最强,目前对大鼠睾丸ALR表达尚无深入的研究;本实验研究不同年龄段大鼠睾丸组织中肝再生增强因子的表达水平、表达部位、以及表达的方式,进而探讨睾丸ALR与睾丸发育、精子生成以及生殖活动的关系;同时探究睾丸组织ALR表达是否参与了肝脏的再生过程中,进一步了解睾丸ALR表达的特性及作用方式。

The gonad index of testis at this stage is 0.037%, and the amount of spermatogonia is increased quickly. There is some linear germ plasm in the cytoplasm of spermatogina. In ovary at this stage it is mostly composed by oocyte of phase 2 which the character is the appearance of yolk nucleus, and no zona radiate in membrane. The mean GI of ovary is 1.95%. From Sep to Oct gonad is at stage III which testis is composed by lots of spermatogina and few spermatocytes, and the mean GI of testis at this stage is 0.086%. In ovary the ooctyes at phase 3 are in dominate position, the yolk nucleus disappear. And the GI of this stage is 3.35%. Both testis and ovary are at stage IV in Nov. hi testis the germ cells are in spermiogenesis, and the mean GI is 0.93%. hi ovary the oocytes are mostly at phase 4, which are filled in the cytoplasm with vitellin granule, and the zona radiate in membrane begins to formation. Nucleus moves to one side of the oocyte gradually. The mean GI of ovary at this stage is 9.37%.

The neurohypophysis is only found in the dorsal region between the RPD and the PPD. The growth hormone cells do not differentiate in the PPD of the adenohypophysis, occupying 2/3 of the PPD until the larva is 5 days old. The other hormone-producing cells in the RPD and in the PT do not differetiate. In the 10-day old larva, the hormone-producing cells except the GH cells in the adenohypophysis do not differentiate. In 15-day old larva, the adrenocorticotropic hormone cells differentiate in the RPD and the other hormone-producing cells in the adenohypophysis do not differentiate. In the 30-day old larva, the all kinds of hormone-producing cells are formed in the adenlhypophysis.

To investigate whether the expression of cdc2 and cyclin B1 in spermatogenic cells during spermatogenesis is actually a temperature dependent event, in situ hybridization, Western blotting and immunohistochemistry analysis were used to study the expression of cdc2 and cyclin B1 in normal and cryptorchid testis. Results showed that heat would differentially hurt male germ cells in different developmental stages during spermatogenesis, especially the pachytene primary spermatocytes. Most of spermatogonia in contralateral cryptorchid testis were not harmed fatally by heat as yet, indicating that spermatogonia could resist to beat to a certain extent. In this case spermatogonia could develop to pachytene/diplotene primary spermatocytes, but they could not acquire the ability to complete the transition from mitosis to meiosis, and then appeared to go through apoptosis. Therefore, we could not find the descendants of meiosis: secondary spermatocytes and round spermatids, elongated spermatids and spermatozoon. The abdominal temperature had no significant influence on the transcription of cdc2 and cyclin B1 in the spermatogonia and pachytene/diplotene primary spermatocytes. In normal rabbit testis, cyclin B1 increased in the pachytene/diplotene primary spermatocytes before meiosis and reached its peak in the spermatids.

为了解精子正常发生过程中cdc2和cyclin B1表达的低温依赖性,我们利用原位杂交和免疫组化等方法,研究了正常和隐睾精子发生过程中cdc2和cyclin B1的转录和翻译调控活动,结果表明:(1)热对各阶段的雄性生殖细胞都有损害,粗线期的初级精母细胞尤为敏感,实验性隐睾内的精原细胞尚未完全受到"致命"影响,说明精原细胞对热有一定的耐受性,但即使成为粗线期/双线期初级精母细胞,却未能获得由有丝分裂过渡到减数分裂的能力,呈现不同程度的凋亡,所以在整个切片中找不到源自减数分裂的产物----次级精母细胞、圆形精子细胞,更谈不上长形精子细胞和精子的形成;(2)腹腔高温未明显地影响隐睾精原细胞和粗线期/双线期初级精母细胞中cyclinB1和cdc2的转录,说明高温并不是通过影响cyclin B1和cdc2的转录活动而导致生精过程阻断的;(3)正常兔睾丸组织中,〓在精原细胞和粗线期/双线期精母细胞中均有表达:cyclin B1蛋白在减数分裂前期的粗线期/双线期初级精母细胞中的表达量增加,于变态末期的精子细胞中达高峰。

The results showed that taurine has no significant influence on testis index, epididymis index, spermaduct index, penis index and testis tectology of baby and young rats, but can make old rat testis tectology better, prevent convoluted seminiferous tubule degeneration, germ cell distortion and leydig cell atrophy. Taurine increase the level of T, E2 and LH in baby rat obviously, but has no significant effect on the level of FSH. The level of T and LH was obviously increased by taurine in young and old rats, but the level of E2 and FSH has no significant changes.

结果证明:牛磺酸对幼年、青年、老年大鼠睾丸指数、附睾指数、输精管指数和阴茎指数没有明显影响;对幼年、青年大鼠睾丸组织形态没有影响,但可明显改善老年大鼠睾丸组织形态,阻止曲细精管退化、生殖细胞变形和间质细胞萎缩;显著促进幼年大鼠 T 、 E2、 LH 分泌,而对 FSH 没有明显影响;明显促进青年和老年大鼠 T 和 LH 分泌,而对 E2和 FSH 没有明显影响。

If the spermatic cord to connect the testis short channel peritoneal inguinal canal stenosis or prematurely closed, and connected at the bottom of the scrotum gubernaculum testis missing, testis and surrounding tissue with adhesion or formation of adhesions, scrotal hypoplasia, testicular gubernaculum is not along the direction of walking enter "岔道," and so the situation can be caused by cryptorchidism.

如连接睾丸的精索过短,腹膜信道腹股沟管狭窄或过早闭合,与阴囊底部相连的睾丸引带缺失,睾丸与周围组织粘连或形成粘连带,阴囊发育不良,睾丸未沿引带方向行走而进入&岔道&等等情况都可造成隐睾。
