副淀粉

With corn embryo being coproduct in corn starch production as material, glutathione was extracted through hot water extraction after supercritical CO2 fluid extraction and ultrasound wave treatment. The results showed that The optimum conditions of hot water extraction are solid; liquid 1:15, temperature 90 ℃, pH3.0, time is 15 min. On these conditions GSH yield is 97 mg/100 g corn embryo.

以玉米湿法加工淀粉副产物玉米胚芽为原料，经超临界CO2萃取脱脂、低温超细粉碎处理后超声波破碎提取超氧化物歧化酶。

In this thesis the corn corcule as a coproduct material is used toextract and depurate the tert functional food raw material-GSH with the purpose of providing the industryproduction technique. By this project, It can extend the corn industry chain utilitily, cut down the cost of thecorn alcohol and starchy and the corn high additional value enterprise can be promoted sigiificantly. It canpromote the development of the corn economy in JiLin province and develop the palae-industry depot innortheast.

为改变这一现状，促进吉林省玉米经济的发展，本研究以玉米酒精厂及淀粉厂副产物玉米胚为原料，以提供产业化生产技术为目的，采用高新技术实现玉米副产物高附加值综合利用，提取纯化出具有国际先进水平的第三代功能食品原料玉米还原型谷胱甘肽，有效延长玉米产业链，降低玉米酒精及淀粉的成本，实现玉米深加工副产物的高附加值综合利用，有力促进吉林省玉米经济发展，振兴东北老工业基地。

In our country, the corn protein was abundant, but it was utilized insufficiently and was discharged wastefully for its unbalanced amino acid composition and insolubility.

玉米蛋白是玉米淀粉生产中的副产物。

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。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
