兽用抗寄生虫药物新剂型及其新技术的研究进展

兽用抗寄生虫药物由于使用频繁,其给药技术研究一直备受重视.目前,兽用抗寄生虫药物新剂型和新技术的研究主要集中在缓释控释制剂和脂质体制剂,其次是透皮给药系统、微囊、微球、环糊精包合物、固体分散体等.但这些新剂型和新技术大多还处于研究阶段,在处方设计或制剂工艺方面都还存在一些问题,今后应加强这些新剂型的工艺和技术研究,以真正发挥这些新剂型的优点.     

人胰岛素原基因转染绵羊成纤维细胞及细胞株的建立

从动物耳皮肤组织采样 ,采用将组织块剪碎后直接贴附于培养瓶底部的方法进行原代培养 ,该方法使原代细胞出现率及可传代率均达到 10 0 %。根据上皮样细胞和成纤维样细胞贴壁紧实程度的不同 ,用 0 .0 5 %的胰蛋白酶-EDTA对其进行消化 ,可将两种不同类型的细胞进行分离和纯化。通过脂质体介导 ,以BLG -hINS(含乳球蛋白调控基因的人胰岛素原基因 )基因作为目的基因、GFP(绿色荧光蛋白 )基因作为标记基因共转染绵羊成纤维细胞 ,经G - 4 18筛选后 ,得到转染细胞。对转染的细胞分别用单细胞显微操作法和有限稀释法进行细胞克隆 ,两种方法均可得到克隆细胞。选形态正常、生长均匀的 5个细胞克隆进行PCR检测 ,结果 5个克隆均转有GFP基因 ,其中两个转有BLG -hINS基因。高代培养细胞、转染细胞和克隆细胞经核型分析后 ,染色体数目均为 2 7对 ,表明绵羊耳的成纤维细胞建立细胞株后 ,可以作为外源基因转染的有效供体细胞。     

牛胎儿成纤维细胞分离与体外培养

本研究以 4 5d牛胎儿为材料 ,使用 0 .2 5 %胰酶 + 0 .0 4 %EDTA消化液 ,分离得到牛胎儿成纤维细胞 ,体外培养传代至第 2 8代。本实验描绘出牛胎儿成纤维细胞生长曲线 ,并发现α MEM是一种适合牛胎儿成纤维细胞生长的培养基。分离得到的牛胎儿成纤维细胞传至第 1 8代时核型仍然正常 ,冷冻、解冻后细胞可继续传代

Network on veterinary medicines initiated by the European Federation For Pharmaceutical Sciences

The European Federation for Pharmaceutical Sciences (EUFEPS) was founded 25 years ago by more than 20 national pharmaceutical societies and faculty members. As a pan‐European organization, it brings together pharmaceutical societies as well as academic, industrial and regulatory scientists engaged in drug research and development, drug regulation and education of professionals working in these fields. EUFEPS represents pharmaceutical sciences in Europe and is recognized as such by both the European Commission and the European Medicines Agency. EUFEPS cooperates with the European Federation of Pharmaceutical Industries and other European organizations and maintains global connections with agencies such as the US Food and Drug Administration and the American Association of Pharmaceutical Scientists. EUFEPS has established specified networks forming the basis of its activities. The creation of a Network on Veterinary Medicines is prompted by the manifold problems resulting from the use of veterinary drugs and its inherent interconnections with human medicine, environmental and public health. A long‐term goal of this initiative was to expand the spectrum of available therapeutics for use in animals, including the development of innovative delivery systems.     

Acupuncture and traditional Chinese veterinary medicine for treatment of a mare with rectal paralysis

An 8‐year‐old Appaloosa mare with rectal paralysis due to a cosmetic ethanol ‘tail block’ was treated with traditional Chinese veterinary medicine treatments including acupuncture and herbal medicine. Her rectal and tail tone gradually improved after the treatment. At 4 months after initial presentation, the mare was able to produce faecal piles on a regular basis, and manual evacuations were no longer needed. Significant improvement was within 30 days of beginning treatment. At 8 months, the owner indicated that the mare had normal defaecation, was able to swish the tail from side to side and lift the tail to urinate, and had no evidence of straining to defaecate or colic.

动物医学临床教学数据库的构建与初步应用

动物医学专业不仅要求学生掌握扎实的理论知识,还需要具有丰富的临床实践经验。为了实现该目标,除了要求授课教师对专业知识融会贯通,更需要拥有大量典型的临床病例资料。以安徽农业大学动物医院和畜禽疾病诊断中心为平台,收集大量宝贵的临床病例资料和最新的临床诊疗技术,构建了动物医学临床教学数据库,使得诊疗动物种类多样化,案例信息全面化、系统化。该数据库的建成和应用,为临床教师提供了丰富的教学素材和资料,亦提升了学生的学习兴趣,促进了动物医学专业的教育教学发展。
