沙参麦冬汤对慢支模型大鼠肺脏抗氧化能力及其组织结构的影响

【目的】:探讨沙参麦冬汤对混合烟雾所致慢性支气管炎模型大鼠肺脏组织的抗氧化能力及对肺脏组织结构的影响。【方法】:60只SD大鼠随机分为正常对照组、慢支模型组和沙参麦冬汤组。采用混合烟雾吸入法复制慢性支气管炎模型大鼠,烟熏期40d。正常对照组与慢支模型组灌胃生理盐水10mL/kg.d,沙参麦冬汤组灌服沙参麦冬汤10mL/kg.d(2g生药/mL),灌胃期30d。灌胃第30d,剖杀大鼠,测定右肺组织匀浆的超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、过氧化氢(CAT)的活力和丙二醛(MDA)的含量。左肺组织进行病理切片光镜观察。【结果】:沙参麦冬汤显著提高烟熏大鼠肺脏组织SOD活性和GSH-Px活性,对肺脏组织CAT活性无显著影响,可降低肺脏组织中MDA含量。正常对照组无明显病理形态学改变,慢支模型组肺泡腔不规则扩大,肺泡间隔破裂,融合成大泡,炎性细胞浸润,沙参麦冬汤组肺泡壁增厚,肺间质炎症细胞浸润。【结论】:沙参麦冬汤可以提高烟熏大鼠肺脏的抗氧化功能,减少氧化应激损伤。沙参麦冬汤能改善烟熏大鼠肺脏组织结构的损伤程度,但对肺组织和支气管的抗炎作用不明显。

Students' note-taking behaviors and the efficacy of providing the instructor's notes for review

College students viewed a videotaped lecture with or without taking notes. Average performance between the two groups did not differ on an immediate test. The encoding effect of note taking was therefore unsupported. Two days later, note takers reviewed their notes while listeners reviewed the instructor's notes in preparation for the delayed exam. Subjects who reviewed the instructor's notes achieved significantly more, on factual items, than did subjects who reviewed their own relatively brief and unorganized notes. Thus, listening to a lecture and subsequently reviewing the instructor's notes prior to a delayed exam leads to relatively higher achievement than does the traditional method of taking and reviewing personal lecture notes.

Noncognitive Constructs and Their Assessment in Graduate Education: A Review

We reviewed the literature on "noncognitive" predictors-specifically, personality as it pertains to graduate education. The review is divided into 3 sections. In the first section, we reviewed measures typically used in studies of graduate school outcomes, such as attrition and time to degree. We also reviewed which student qualities faculty and administrators said they desired and cultivated in graduate programs. We also noted that there are many qualities faculty ranked high in desirability but which could only imperfectly be gleaned from sources such as letters of recommendation and personal statements. In the second section, we reviewed general personality factors (e.g., the "Big Five"), specifically, definitions, measures, correlates, and the validity of those measures. We concluded with a discussion of how personality factors might be used in admissions and guidance applications for graduate education.

Reviewing and Critiquing Computer Learning and Usage Among Older Adults

By searching the keywords of “older adult” and “computer” in ERIC, Academic Search Premier, and PsycINFO, this study reviewed 70 studies published after 1990 that address older adults' computer learning and usage. This study revealed 5 prominent themes among reviewed literature: (a) motivations and barriers of older adults' usage of computers, (b) age-related differences in computer learning and usage, (c) instructional tips and design, (d) changes in attitudes and benefits, and (e) Internet usage. The limitations of the studies are reviewed and suggestions for future research are discussed.
