小管形成

The ampullae join the ducts of two other saclike organs, the seminal vesicles, to form short and straight tubes called ejaculatory ducts.

两侧壶腹分别汇合另外的两个囊状器官——精囊腺的管道，形成短而直的小管，是为射精管。

Under transmission electron microscope, cellular swelling in brain tissue, nuclear membrane of neuron has incisures, some chromatic agglutination, group A mainly appears endoplasmic reticulum distention and glial cell endocytosis, while group B mainly appears histolysis; cardiac fibrous structure is chaotic, Z line concentrates, mitochondria swelling, nucleus deform; the ecphyma of podocyte becomes thinner and longer like villus, some mix together, plasma membrane infolding of renal cells decreases, mitochondria malformation, cells in lumens.

透射电镜观察显示，试验组动物脑组织细胞肿胀，神经元核膜出现切迹，部分染色质凝集，A组动物出现内质网扩张及胶质细胞吞噬现象，B组动物以组织溶解为主；心肌纤维结构紊乱，Z线聚集，收缩带形成，线粒体肿胀，核变形；肾小球足突细长，绒毛化，并可见足突融合，肾小管上皮细胞质膜内褶减少，线粒体畸形，管腔可见脱落细胞，上述改变均以B组为著。

Methods: 1. Male Sprague-Dawley rats were established renal calcium oxalate calculi model. 2. The different dose of LBP, medlar soak and apozem was given. The calcium oxalate crystallization, the renal cell apoptosis and the renal free radical level were detected. 3. The relationship of the renal cell apoptosis index, the renal free radical level and the calcium oxalate crystallization grade in the kidney tubule was determined.

1、给大鼠建立肾草酸钙结石模型；2、予以不同剂量的枸杞多糖，不同浓度的枸杞浸泡剂和煎剂灌喂，比较肾小管内草酸钙结晶的形成，测定肾小管上皮细胞的凋亡指数，自由基水平；3、分析结晶等级评分、细胞凋亡指数和自由基的相互关系，判断枸杞多糖预防肾草酸钙结石的作用机制和效果。

Hyaline and erythrocytic casts, glycogen deposition in tublar epithelial cells, and renal interstitial fibrosis also were observed in model rats.

肾小管上皮细胞内有糖原沉积，肾小管蛋白管型和红细胞管型，肾间质纤维化，伴发间质脓肿形成。

Results the orifices of dentinal tubule were mostly occluded in Gluma samples and partly occluded in Bisblock samples. Resin layer were observed in Single Bond 2 samples.

结果 Gluma组牙本质小管开口几乎堵塞，Single Bond 2组牙本质表面形成厚的树脂层，BisBlock组牙本质小管开口部分堵塞。

Results: No fiber layer and inflammatory tissues around any inserted implants were founded. New-grown osteoid tissue appeared faster in Bio-Ti implants than pure titanium and matured bone tissues comprise bone trabecula and Haversian canals appeared in 6 weeks, while at least 12 weeks needed to form matured bone tissue in control groups.

结果：所有种植体周围没有发现明显炎症组织或形成纤维层，Bio-Ti种植体组新生类骨组织生长较快，并于6w时已形成含有骨小梁及哈弗氏小管结构的较成熟骨组织，对照组12w时新生骨组织基本成熟。

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。

The expressions of VEGF mRNA in renal cortex in B and group C increased greatly compared with A group at 8th week(P.01), And the expression was decreased more in C group than that in B group at the 8th week;④The light microscopes results showed that no pathological changes in group A; pathological changes were much obvious in group B:glomerular capillary lumen tumbling,lumens blocked,mesangial region widened,basal lamina thicking,mesenterium base inceased,the volume of glomerulus become large,cell population increased,renal tubule vacuolization, renal interstitium was infiltrated by lots of lymphocyte and mononuclear macrophage; pathological changes in group C was light,only see glomerular capillary lumen lightly stegnosis,few lymphocyte infiltrating.

免疫组化结果显示第8周B组大鼠肾皮质VEGF蛋白含量较A组显著增加(P.01)，C组VEGF含量较B组有明显减少(P.01)，C组较A组表达量仍然增加(P.01)；③第8周B组肾皮质VEGF mRNA表达较A组有明显上调(P.01)，与B组相比，辛伐他汀可以明显减少C组肾皮质VEGF mRNA表达；④光学显微镜下A组肾小球毛细血管腔均匀一致，无狭窄，肾小管-间质无炎症细胞浸润。B组则病变较明显：大鼠肾小球毛细血管袢塌陷，管腔闭塞，系膜区增宽，基膜增厚和系膜基质增多，肾小球体积增大，出现玻璃样变；肾小管尤其是近区小管肿胀、变性、空泡形成，肾间质可见大量淋巴细胞和单核巨噬细胞浸润。C组病变较轻，可见肾小球毛细血管管腔轻度狭窄，肾小管-间质见少量淋巴细胞浸润。

In the group of lased 60s the dentin tubles appeared cracking and some dentin tubles were opened.

激光60秒组对根管壁有过分熔融，形成裂纹而且不能完全封闭牙本质小管。

Among the failed eyes, 45 of them were tear bag inflammation, 18were blocked small tear ducts and among 17eyes, 7 became pretend ducts.
