陶瓷在每个历史时期各有其特点,承载着那一时期下的社会背景,制造者使用者的审美意趣,对美的理解,设计师的主张,政治文化思想等等。因此,陶瓷亦是艺术活动的结晶,包含着这一时期造型语言、设计思想、社会背景、制作工艺等。本文采用艺术人类学视野对中欧陶瓷进行比较分析,用联系发展的眼光看待作品背后的形成过程和文化蕴涵。以陶瓷作品为出发点,用全局观探析构成陶瓷作品的各部分因素之间的联系,并进行对比,以此了解中欧艺术界运动趋势异同。

Asian Journal of Andrology 2012年第2期14卷 330-334页

作者： mi mi Oh Jin Wook Kim Myeong Heon Jin Je Jong Kim Du Geon moon Department of Urology Korea University Medical Center Seou1435-766 Korea Department of Urology Korea University Medical Center and Korea University Institute of Regenerative Medicine Seou1435-766 Korea

This study was performed to assess serum testosterone alterations induced by paradoxical sleep deprivation （PSD） and to verify their attenuation during sleep recovery （SR） based on different durations and ages. Wistar male rats aged 12 weeks for the younger group and 20 weeks for the elder group were randomly distributed into one of the following groups： a control group （cage and platform）, 3-day SD, 5-day SD, 7-day SD, 1-day SR, 3-day SR and 5-day SR groups. For PSD, the modified multiple platform method was used to specifically limit rapid eye movement （REM） sleep. Differences in the testosterone and luteinizing hormone levels between the younger group and the elder group according to duration of PSD and SR recovery were analysed. Testosterone continued to fall during the sleep deprivation period in a time-dependent manner in both the younger （P=-0.001, correlation coefficient r=-0.651） and elder groups （P=0.001, correlation coefficient r=-0.840）. The elder group showed a significantly lower level of testosterone compared with the younger group after PSD. Upon SR after 3 days of PSD, the testosterone level continued to rise for 5 days after sleep recovery in the younger group （P=0.013）, whereas testosterone concentrations failed to recover until day 5 in the elder group. PSD caused a more detrimental effect on serum testosterone in the elder group compared to the younger group with respect to decreases in luteinizing hormone （LH） levels. The replenishment of serum testosterone level was prohibited in the elder group suggesting that the effects of SD/SR may be age-dependent. The mechanism by which SD affects serum testosterone and how age may modify the process are still unclear.
