Between P14 and P21,CIAPIN1 immunoreaction in the brain,heart and liverbecame much lower. However,between P21 and P28,CIAPIN1 immunoreactionin the heart,brain,liver and skeletal muscle became much lower,while with thekidney development,CIAPIN1 immunoreaction in the kidney became higher. Invarious tissues from adult mouse,CIAPIN1 immunoreaction could be seen incardiac muscle cell,brain,hepatocyte,epithelium of renal tubule,skeletal muscle,lung tissue,gastric mucosa and gland,acinus lienalis.2. Distribution of CIAPIN1 in normal fetal and adult human tissuesTo reveal the possible physiological role of CIAPIN1,we examined theexpression and distribution of CIAPIN1 in fetal and adult human tissues usingimmunohistochemistry. We found that CIAPIN1 was ubiquitously distributed infetal and adult tissues,and was localized in both the cytoplasm and the nucleus.

然而，在3个月大的成年鼠中，CIAPIN1阳性反应物在心、脑、肝和肾小管中的表达强度要低于P28小鼠；但CIAPIN1阳性反应物在成年鼠骨骼肌中较P28小鼠高。2、CIAPIN1蛋白在人5个月胚胎及成人多器官组织内的表达在人5月胚胎多器官组织中，CIAPIN1阳性反应物见于心脏、胆囊单层柱状上皮和粘膜、结肠粘膜、小肠粘膜和绒毛、肝脏、直肠腺体、胃粘膜、肾上腺束状带、甲状腺滤泡、脾索、胸腺小叶间隔、皮肤真皮层和汗腺、睾丸白膜和间质、脑组织内神经元和神经胶质、肺小支气管和肺泡、骨骼肌、肾脏皮髓质和肾小管、子宫内膜、胰腺腺泡和胰岛、卵巢、输卵管粘膜等绝大多数组织细胞。

The simulation results of the cylinder-block model were given in the article, consistent with that of Middlemen"s. It was shown that the block part could improve the uniformity of the flow distribution. The analysis of the flow field of some materials with different power-law factor in the die designed by Mckelvey was close to that of Mckelvey"s. It was shown that the flow distribution was uniform in the die that can producesheets with 1200mm in width. During the analysis the flow channel was divided into several parts to get the details about the fluid flow in each area. A conclusion was drawn after analyzing the influence of the die pressure on the flow distribution, that the higher pressure is good for the output and bad for the uniformity of the distribution. Simulation of the die applying the cylindrical main runner showed the fact that when the cylinder replaced the cone the change of uniformity was trivial. The uniformity of the non-block flow channel was so poor that the block in the proper position of the die channel was necessary. The project of the die for the wider sheet was put forth, and the analysis of the fluid flow in the die was shown.

Histologically, the seminiferous tubules contained numerous Sertoli cells and more Sertoli-spermatozoa complexes, accompanied by the depletion of Leydig cells with deeply stained nuclei. Mature spermatozoa were stored up in the epididymis, but only a few in the efferent ducts. In the second place was testicular atrophy（32/120; 26.7%）. The seminiferous tubules showed moderate to severe inactivity of spermiogenesis with evidence of only spermatogonia, spermatocytes and Sertoli cells. The Leydig cells were obviously decreased in numbers associated with decrease of lipid droplets in their cytoplasms. Testicular hypoplasia was the third disorders（22/120; 18.3%）. Only a few spermatogonia and Sertoli cells appeared without any spermiogenesis. The associated changes was decreased in Leydig cells and fibrous hyperplasia in the interstitium.Epididymal stones were sometimes found（12/120; 10%）. Grossly, yellowish-white nodules with various sizes and firm in consistency were observed in the epididymis and the front efferent ducts. Microscopically, the epididymal ducts were dilated with voluminous spermatozoa storage, even showed calcification in severe cases. The deposited calcium salts were stained positively by Von Kossa and Alizarin red methods.Amyloidosis was also detected in 10 roosters（8.3%）. Eosinophilic, homogeneous, amyloid-like substances were deposited mainly in the testicular interstitium and the periphery of blood vessels. These substances showed positive reaction by Congo red staining. Five roosters（4.2%）had Marek's lesions in the testis, epididymis and peripheral nerves with infiltration of pleomorphic lymphocytes. Only one case showed epithelial necrosis of seminiferous tubules accompanied by fibrous proliferation in the interstitium.

结果发现，在总共搜集的120个病例中，其中因年老所导致的产精力不佳为最多，占38例（31.7%），於镜下可见大量精虫黏附於Sertoli cell的表面，并可见Sertoli cell数量明显增多而Leydig cell明显减少，且其细胞核呈现浓染的现象，而在其副睪中仍可见到成熟精虫蓄留於管腔中，但在其输精管内却只有少量精虫存在；其次为睪丸萎缩，占32例（26.7%），镜下可见中度至重度无造精作用，其生精小管中只见到精母细胞、精原细胞及Sertoli cell存在，但Leydig cell数量明显减少且其细胞质内的脂质也明显减少；睪丸发育不全，占22例（18.3%），於生精小管内只见到精母细胞及少量Sertoli cell存在，不见造精细胞分化，於生精小管间质可见Leydig cell减少并伴随结缔组织增生；副睪结石，占12例（10%），肉眼下可在副睪及输精管前段见到黄白色大小不一的结节，触感坚硬，於镜下可见副睪管扩张并有大量成熟精虫蓄积，严重时可见钙化现象，以Von Kossa及茜素红染色均呈阳性反应；类淀粉沉著症，占10例（8.3%），镜下在睪丸间质及血管周围可见粉红均质样的物质沉积，以刚果红染色成阳性反应；马立克病，占5例（4.2%），镜下可在睪丸、副睪实质及周边神经内均可见到嗜碱性大小不一的淋巴样细胞浸润；睪丸坏死，占1例（0.8%），镜下可见生精小管上皮细胞坏死脱落及间质结缔组织增生。
