摘要： Histology and embryology are prerequisite for understanding the complexity of cell and tissue organization, function and development. The aim of this study was to examine the attitudes of medical students toward relevance of histology and embryology in their pre-clinical and clinical medical practice. The study sample consisted of 900 undergraduate students of 1st and 6th study year at the School of Medicine in Belgrade, Serbia. Data were collected using an anonymous questionnaire. Senior students reported the relevance of histology and embryology knowledge for learning pathology, dermatology, physiology, gynecology and obstetrics, pathophysiology and pediatrics. Examination of students' attitudes revealed that 1st year participants more often acknowledged histology and embryology as being of great importance for their professional career. Analysis according to gender indicated that female students consider embryology as of greater importance for further medical education and future clinical practice than male students. Overall, study results suggest that medical students have a positive attitude toward histology and embryology undergraduate course. This evidence could be used as an additional motive for the development of histology and embryology courses, with special emphasis on practical application of knowledge in clinically-oriented setting.

关键词： 双语教学   成绩分析   统计分析  

摘要： 对比分析我校2009—2013级五年制临床医学专业双语班和中文班组织学与胚胎学期考成绩,初步了解其双语教学效果,为今后深化双语教学改革提供参考依据;结果显示:2009—2010级双语班和中文班学生期考成绩无明显差异,2011—2013级双语班成绩优于中文班学生,因此,我校开展的组织学与胚胎学双语教学取得了较为满意的效果。

关键词： 人体解剖学   组织胚胎学   教学改革  

摘要： 人体解剖学和组织胚胎学是我国医学教育的主要课程，由于人体解剖学和组织胚胎学具有内容多、描述多、名词多及需记忆点多等特点，因此学生学习起来往往具有一定的难度，并且也难以对其产生兴趣。对此，学校和教师应当积极对人体解剖学和组织胚胎学进行教学改革，确立新的教学目标和教学理念，改进固有教学方法，引入新的教学手段，转变传统教学模式，注重对学生知识和能力的双重培养。本文主要针对人体解剖学和组织胚胎学教学改革进行了探讨，希望能够对这方面教学工作有所助益。

摘要： 《组织胚胎学》是中医院校中重要的一门基础科目,我们建立了该课程的建构主义教学模式,以学生为中心,在整个教学过程中由教师起组织者、指导者、帮助者和促进者的作用,利用情境、协作、会话等学习环境要素充分发挥学生的主动性、积极性和首创精神,最终达到使学生有效地实现对当前所学知识的意义建构的目的。

关键词： 双酚 A   小鼠胚胎   组织器官   研究分析  

摘要： 目的：研究分析双酚 A 对小鼠胚胎生长发育和组织器官形态分化的影响。方法通过植入后全胚胎模型，将9．5日龄 BaB ／C 小鼠胚胎与含双酚 A 的大鼠即刻进行离心血清培养，时间为48h（双酚 A 浓度分别为0、40．0、60．0、80．0以及100．0mg ／L）。对双酚 A 对小鼠胚胎生长发育和组织器官形态分化的影响进行观察。结果胚胎在体外的生长发育，受到双酚 A 浓度的影响，双酚 A 剂量越高，对胚胎在体外的生长发育影响越大，表现出显著的剂量反应关系。当双酚 A 大于等于60mg ／L 时，则可造成 VYS（卵黄囊）生长以及血管分化不良，以及生长缓慢和形态分化异常，更有甚者出现体位异常和形态各异的畸形。结论双酚 A 在相对较高的剂量情况下，不但会对体外培养的小鼠胚胎造成一定的毒副作用，究其原因可能是卵囊胎盘结构与功能影响所致；而且会造成 VYS（卵黄囊）生长以及血管分化不良、生长缓慢和形态分化异常以及出现体位异常和形态各异的畸形。

摘要： 目的:研究高职院校组织学与胚胎学课程教学中应用PBL教学法的效果。方法:在我校2014届临床医学专业中随机挑选出2个班作为本次研究的对象,分成实验班(43人)和对照班(46人),在组织学与胚胎学课程教学中,其中实验班学生采用PBL教学法,对照班学生采用传统教师讲授为主的教学方式,就两班学生学习成果进行对比分析。结果:实验班学生的理论考核成绩、技能考察成绩均高于对照班,同时实验班学生对教学模式的满意度高于对照班,P<0.05。结论:高职组织学与胚胎学课程教学中应用PBL教学法有助于提高学生的学习成绩,营造良好的课堂氛围,激发学生的学习兴趣。

摘要： 传统《组织胚胎学》实验教学需借助显微镜对组织、器官切片进行观察,使得其实验课的实施在时间和空间上受到了一定的影响。随着现代科学技术的发展,将数字切片及网络课堂教学手段引入《组织胚胎学》的实验教学可弥补传统实验教学的缺陷。初步探索构建该课程数字化实验教学体系。

摘要： Background Somatic embryogenesis in conifer species has great potential for the forestry industry. Hence, a number of methods have been developed for their efficient and rapid propagation through somatic embryogenesis. Although information is available regarding the previous process-mediated generation of embryogenic cells to form somatic embryos, there is a dearth of information in the literature on the detailed structure of these clusters. Methodology/Principal Findings The main aim of this study was to provide a more detailed structure of the embryogenic tissue clusters obtained through the in vitro propagation of the Norway spruce (Picea abies (L.) Karst.). We primarily focused on the growth of early somatic embryos (ESEs). The data on ESE growth suggested that there may be clear distinctions between their inner and outer regions. Therefore, we selected ESEs collected on the 56th day after sub-cultivation to dissect the homogeneity of the ESE clusters. Two colourimetric assays (acetocarmine and fluorescein diacetate/propidium iodide staining) and one metabolic assay based on the use of 2,3,5-triphenyltetrazolium chloride uncovered large differences in the metabolic activity inside the cluster. Next, we performed nuclear magnetic resonance measurements. The ESE cluster seemed to be compactly aggregated during the first four weeks of cultivation;thereafter, the difference between the H-1 nuclei concentration in the inner and outer clusters was more evident. There were clear differences in the visual appearance of embryos from the outer and inner regions. Finally, a cluster was divided into six parts (three each from the inner and the outer regions of the embryo) to determine their growth and viability. The innermost embryos (centripetally towards the cluster centre) could grow after sub-cultivation but exhibited the slowest rate and required the longest time to reach the common growth rate. To confirm our hypothesis on the organisation of the ESE cluster, we inves
