Benefits from peer teaching in the dental gross anatomy laboratory

This study examined the impact of implementing a rotating dissection schedule on the attitudes and performance of first-year dental students in the gross anatomy laboratory at the University of Kentucky. In 2002-2003, half of the students assigned to each cadaver dissected the assigned objectives during the first 90 min of the laboratory session. During the last 30 min, the non-dissecting group members came into the laboratory and had the day's dissection demonstrated and explained to them via peer instruction. Dissection responsibilities rotated with each laboratory session. Eighty-eight percent of student participants were satisfied with the rotating dissection approach according to a mid-term survey, and this satisfaction level remained unchanged at the end of the semester for most students. Students' perceptions of the quality of peer laboratory presentations varied, with only 44% rating them as good or better. Eighty percent of students perceived that rotating dissection did not impede their performance, and this was confirmed by analysis of grade data. Student satisfaction and the ability to devote additional weekly curriculum time to studying anatomy in a very compressed curriculum were the main student-described benefits.     

职业性接触苯、甲苯、二甲苯对子代行为影响的初步探讨

为探讨职业性接触苯、甲苯、二甲苯对子代行为的影响，以４６名父母生育期接触苯、甲苯、二甲苯的儿童为暴露组；抽取与暴露组同年龄、同性别、同班级、其父母无任何职业有害因素接触史的５８名儿童为对照组，用ＷＩＣＳ－Ｒ（韦克斯勒儿童智力量表）对研究对象进行智力测验，用ＮＢ－Ｉ型视运动反应仪测试视简单反应时。结果显示，接触组各智力测验的得分均低于对照组，视反应时指标慢于对照组，差异有显著意义；进一步的分层分析结果显示，母接触组的各项得分均低于对照组，而父接触组的各项得分与对照组之间差异无显著意义。     

合肥市部分人群SARS认知及行为态度

目的　了解合肥市部分人群对 SARS的认知情况及行为态度。方法　对合肥市两个社区及一所大学的部分人群共 1332人进行现况调查 ,比较不同性别、职业、文化程度对 SARS的总体认知水平。结果　合肥市人群对 SARS的认知情况尚好 ,总体平均得分 ( 15 .0 2± 1.98)分 (总分 18分 )。结论　合肥市居民对 SARS的认知水平总体较高 ,但存在群体差异 ,卫生行政部门应加强对公众的宣传教育 ,以提高全体居民的健康意识 ,进而预防 SARS的发生     

Internet tools in the medical classroom

Summary: The Internet contains a vast amount of medically relevant information. In order to access this information, however, many networks require one to master applications written in UNIX, an operating system considered by many not to be user friendly. Although these tools may be available on the campus, it is difficult to teach their use unless there is some immediate benefit to the already busy user. From that standpoint, it is important for instructors to realize that common UNIX applications can be utilized as classroom tools to significantly enhance the learning experience by facilitating teacher/student communication. Also, whilst the student enjoys greater communication with the instructor (and with other students) he/she is also becoming adept at using information management tools.

成人瑞文标准推理测验与韦氏智力测验比较研究

目的:探讨成人瑞文标准推理测验(RSPM)与韦氏成人智力测验(A-WISC)结果之间的差异。方法:对106例在我研究所心理评估中心测试智力的成人研究对象进行上述两项测试,并比较二者之间的差异。结果:成人瑞文智商(IQR)与韦氏智商(IQW)平均值分别为72.87±16.18、67.51±22.84,前者显著高于后者。成人研究对象IQR与IQW差值(IQR-W)之均数为5.36,中位数为6;而标准差为14.55,极差为74(-35至39),四分位数间距为18,变异系数为271.455%。IQR-W在不同性别间无显著性差异。言语智商(IQV)与操作智商(IQP)是否有差异对IQR-W影响不大。IQW在IQR-W高分组与IQR-W低分组间有显著差异(53.47±17.26,82.65±17.97),而IQR在两组间无显著差异。将IQR分别与IQW、IQV、IQP进行相关性研究,结果均具有显著正相关(相关系数分别为0.77、0.73、0.71)。IQR-W与IQW有显著负相关性(相关系数为-0.72),而与IQR无显著相关性(相关系数为0.14)。结论:成人瑞文标准推理测验智商与韦氏智力测验智商有较大差异,故在临床上使用RSPM时应慎重。     

尼莫地平对阿尔茨海默病大鼠脑组织NO、NOS含量及行为学的影响

目的：探讨尼莫地平对阿尔茨海默病（AD）大鼠脑组织一氧化氮(NO)、一氧化氮合酶（NOS）浓度及行为学改变的影响。方法：SD大鼠30只，随机分为空白对照组,AD模型组和尼莫地平组，采用大鼠脑组织立体定位微量注射技术，尼莫地平组和AD模型组用鹅膏蕈氨酸（IBO）1μl(5μg)损毁大鼠双侧迈内特基底核（nbM）建立AD动物模型，空白对照组以0.1mol/L pH7.4PB液代替IBO。尼莫地平组给予尼莫地平0.5mg/kg，空白对照组和AD模型组以生理盐水代替尼莫地平，连续灌胃60d，每d2次，每次2ml。做迷宫试验及跳台试验测学习记忆能力，然后将大鼠断头处死，分离海马及大脑皮质，分别检测NO,NOS含量。结果：AD模型组较空白对照组学习记忆能力显著降低，海马及大脑皮质NO,NOS含量显著升高，尼莫地平较AD模型组学习记忆能力显著升高，海马及大脑皮质NO、NOS含量显著降低。结论：用IBO损毁大鼠双侧nbM可建立AD动物模型，尼莫地平可显著改变AD模型大鼠的学习记忆能力，降低海马及大脑皮质NO、NOS含量。
