原代神经元培养及其在动物疾病研究中的应用 总被引:1,自引:0,他引:1
《当代畜牧》2016,(14)
细胞是生命活动的基本单位,绝大多数生物都由细胞组成,细胞运行着机体一切生长代谢活动。因此,对细胞深入探索、加大力度推动细胞培养技术发展是21世纪人类预防与治疗动物疾病、发展经济生产的关键。目前,原代神经元培养无疑是原代细胞培养中的难点和重点。笔者主要介绍原代神经元的培养技术,分析技术要点,并对原代神经元培养在防治动物疾病中的应用作一概述。 相似文献

悬浮培养技术在生物制药中的应用和展望 总被引:3,自引:1,他引:3
综述了国内外细胞悬浮培养产业化发展现状及其关键技术。细胞悬浮培养是利用生物反应器大规模培养动物细胞生产生物制品的核心技术,结合筛选驯化的高表达细胞株和个性化细胞培养基,控制细胞培养过程,实现提高生产效率及产品质量、降低生产成本的目的,是当前国际上生物制品生产的主流模式。但该技术目前在国内尚未得到广泛应用,生物制品生产仍主要采用病毒产率低、生产成本高、劳动强度大的转瓶细胞培养方式。随着现代生物技术发展,利用细胞悬浮培养技术进行生物制品生产是生物制药行业发展的必然趋势。 相似文献

Summary Generalized cowpox infection in the Patagonian cavy may represent a threat to the health of immunocompromised persons. We report the first case of cowpoxvirus infection in the Patagonian cavy in an educational animal park. The mara developed extensive pox lesions, shedding large amounts of viral particles. The ending of vaccination programmes against smallpox in the late 1970's may lead to an increase in susceptibility of humans to zoonotic poxviruses. 相似文献

Understanding the interactions between nutrition and immune system is crucial for adjusting nutrient allowances in dietary formulations that optimize production efficiency. Among various animal proteins, fish meal (FM) is rich in protein (amino acids), readily available throughout most of the world, and competitively priced against other animal proteins (e.g. milk and blood). In addition, many researchers reported that FM is traditionally recognized as a high digestible protein with a high content of amino acids, vitamins and minerals for pigs. Supplementation of fatty acids by FM and fish oil (FO) is one strategy to modify an animal immune response. As a result of FM and FO effects, those supplementations can result in improved performance and immunity of young animals. 相似文献

选用AA肉鸡进行试验,试验在生产后期进行,试验分为两组:对照组(含有3%的秘鲁鱼粉)和试验组(含有3%的鱼精粉),两组的营养水平接近。试验组平均日增重为47.18g,对照组为47.06g;试验组的料肉比为2.684,对照组为2.745。两者的重要生产性能指标接近,差异不显著。试验结果表明,在生长后期的肉鸡日粮中,使用鱼精粉替代进口鱼粉并不影响试验鸡的生产性能。 相似文献
