Results In the medium and high dose F0 groups, it was observed that the atrophy and incrassation of seminiferous tubule, decrease of spermatogenesis, hyperplasia of interstitial tissue, especially in high dose groups spermatozoon abnormality and nucleolus concentration in the rats testis after DU ingestion for 14 months. The changes became more severe with the prolongation of DU ingestion. Such changes occurred in filial rats (F1) after DC ingestion for 5 months. In the medium and high dose F0 groups, it was observed that a little atrophy of kidney glomerulus, hyperplasia of interstitial tissue after DC ingestion for 14 months, and kidney glomerulus fibrosis happened after DC ingestion for 20 months, such changes occurred in filial rats (F1) after DC ingestion for 5 months In the medium and high dose F0 groups, splenic germinal center and periarterial lymphatic sheaths were hyperplasia , companies with lymphopoiesis after DC ingestion for 7 months, splenic white pulp became more small and sparse after DC ingestion for 20 months.

结果 F0代的中、高剂量组大鼠摄入贫铀14个月后可见雄性的精曲小管萎缩，管壁增厚呈空虚网状，生精细胞层次减少，间质细胞增生，但仍见有精子生成；高剂量组可见到精子呈异型性改变，细胞核浓缩深染，且随着摄入时间延长改变愈趋明显；F1代大鼠摄入贫铀5个月后就有上述改变且更为严重。F0代中、高剂量组大鼠摄入贫铀14个月后肾小球轻度萎缩，间质增生明显，20个月时肾小球萎缩纤维化；F1代大鼠摄入贫铀5个月后就有上述改变。F0代中、高剂量组摄入贫铀7个月时脾脏生发中心和淋巴鞘增生，淋巴母细胞增生活跃，20个月时脾小体减少，生发中心稀疏；F1代大鼠摄入贫铀早期和晚期有类似改变。F0和F1代高剂量组摄入贫铀早期肝脏有炎症细胞浸润，晚期骨髓有核细胞减少，脂肪细胞增加。

Morphologic features ranged from single straight or branching tubules to complex cavitary networks, usually overlying areas of pigment epithelial alteration or subretinal fibrosis.

The difference is significance statistically. Conclusion: Nasal trachea cannula under the guidance of fibrobronchoscope is a high achievement ratio tracheal intubation method with better sufferer tolerance, longer time of detained airtube, higher extubate ratio, and which could avoid or reduce incision of trachea simultaneously, especially suit the chronic pulmonary disease patients.

The composition of the device comprises a substrate and a cover plate. A cross-form groove is disposed on the base material of the substrate; a disperse phase fluid inlet pipe and a fluid outlet pipe are respectively inlaid in the groove to form a coaxial sleeve structure; a continuous phase fluid inlet pipe is embedded in a groove on the two sides and connected with the coaxial sleeve; and the cover plate is hermitically attached to the upper surface of the substrate and seals the groove.

其组成包括基片和盖片：所述基片的基材上开有一个十字型凹槽；分散相流体入口管和流体出口管分别嵌入到凹槽内形成同轴套管结构；连续相流体入口管嵌入到两侧的凹槽内与所述同轴套管相连；所述盖片紧密贴合在所述基片的上表面上将所述凹槽进行密封。

There is a significantly difference between the tubular widthes of obstructive and non-obstructive azoospermic patients. The large number of intratubular germ cells within those tubules with active spermatogenesis cause those tubules to be larger than tubules without sperm production.

而藉由测量细精小管，我们得知造精功能受损患者的细精小管管径明显地较具正常造精功能的细精小管细，原因为造精作用活跃的细精小管内生殖细胞较多，因而造成有精子生成的细精小管管径明显的较没有精子生成的细精小管粗。

The Lithostegia Ching was considered as a member of Peranemaceae for a long time, according to the research,we found that it has the typical scalariform perforation plates,no associated or crossed phenomena,and some region have intact plate,no dimorphic phenomena,no weblike or threadlike remnants,these suggest that The Lithostegia Ching is in a primal evolutional position.

与传统观点不同，我们认为穿孔板仅存在于端壁的管状分子为导管分子，而端壁和侧壁形态、结构相似，有或无穿孔板的管状分子为管胞，蕨类植物中的管状分子主要为管胞。

D. N big mouse model was successfully made by adopting single side kidney cutting with induction, then by 24 week continuos observation on the change of various values of kidney and function, through testing of immunity florescence, electro-scope and optical scope, what we can see from model group is that typical kidney small cell got hardened by knot, and discarded, and dead, also small tube withered, small cell of on base film got thick, cell capsule wall was fibred, and base film got double layered.

实验研究采用单侧肾切除加以链脲佐菌素诱导，成功地复制出糖尿病肾病大鼠模型，对其肾脏结构和功能的改变各项指标，连续进行24周动态观察，并进行免疫荧光、电镜、光镜检测，结果表明：糖尿病肾病模型组可见典型的肾小球节段硬化、废弃、坏死，有大量蛋白管型，肾小球管糖元空泡沉积及脂肪滴，肾小管萎缩，肾小球基底膜明显增厚，球囊壁纤维化，基底膜双层化，有一例结核性肉芽组织及钙化等病理变化。
