反刍动物甲烷生成量的调控

反刍动物体内甲烷的产生是瘤胃发酵能损失的主要原因,减少甲烷产量对提高反刍动物的能量利用率和环境保护均具有重要意义。因此,本文就反刍动物甲烷生成的机制及影响其生成量的因素等方面做一综述,并对降低甲烷生成量的调控方式进行了分析和展望。     

Mammary stem cells： expansion and animal productivity

Identification and characterization of mammary stem cells and progenitor cells from dairy animals is important in the understanding of mammogenesis, tissue turnover, lactation persistency and regenerative therapy. It has been realized by many investigators that altered lactation, long dry periods （non-milking period between two consecutive lactation cycles）, abrupt cessation of lactation （common in water buffaloes） and disease conditions like mastitis, greatly reduce milk yield thus render huge financial losses within the dairy sector. Cellular manipulation of specialized cell types within the mammary gland, called mammary stem cells （MaSCs）/progenitor cells, might provide potential solutions to these problems and may improve milk production. In addition, MaSCs/progenitor cells could be used in regenerative therapy against tissue damage caused by mastitis. This review discusses methods of MaSC/progenitor cell manipulation and their mechanisms in bovine and caprine animals. Author believes that intervention of MaSCs/progenitor cells could lessen the huge financial losses to the dairy industry globally.

推拿手法实践操作综合考核体系的构建——以湖南中医药大学为例

推拿手法实践操作考核是推拿手法考核的重要组成部分,是真实、客观、公平、公正的评价学生动手能力的一种有效的方法和手段。探索出适合现代推拿手法教学和考核的方式是推拿教师必须积极面对的一个重要课题。湖南中医药大学针灸推拿学院推拿教学科研人员经过多年的思考及5年的探索和不断改进,建立了一套利用目测法、体测法和机测法在推拿手法考核中适合本、专科不同专业层次人才的推拿手法实践操作综合考核体系。     

瘤胃十八碳不饱和脂肪酸氢化的研究进展

瘤胃微生物对不饱和脂肪酸的生物氢化作用,限制了其转化效率,使乳脂肪酸组成的调控难以达到理想的效果。不饱和脂肪酸对微生物生长的抑制是氢化的主要原因;氢化的程度主要由瘤胃内环境决定,如瘤胃pH、金属离子浓度等,脂肪酸来源、水平、脂肪酸之间的相互作用以及其他营养因素等均会对脂肪酸的氢化造成影响。本文主要综述了反刍动物饲料中不饱和脂肪酸氢化的过程、氢化相关瘤胃微生物以及影响氢化程度的因素,同时探讨了营养途径调控氢化的方法,为进一步调控乳脂肪酸组成提供依据。
