茜草提取物对大强度耐力训练大鼠股四头肌ATP 酶活性及运动能力影响的实验研究 总被引：2，自引：0，他引：2
目的：探讨茜草提取物对大强度耐力训练大鼠股四头肌ATP酶活性及运动能力的影响，为茜草作为运动补剂提供理论依据。方法：选取24只大鼠，随机分为安静组、训练组和训练加药组。训练组与训练加药组按照训练模型进行为期6周的耐力训练，最后一次训练进行一次力竭性运动，力竭后取股四头肌组织并进行样本处理。内容：通过建立大强度耐力训练大鼠模型，测定运动大鼠力竭运动的时间以及股四头肌ATP酶活性。研究茜草提取物对大强度耐力训练大鼠股四头肌的保护作用。结论：茜草提取物可明显提高大鼠股四头肌在大强度耐力运动中的能量供给，提高了大鼠大强度耐力运动的运动时间。 相似文献

The Shosoin treasures, which include the belongings of Emperor Shomu (CE 701–756) and Empress Komyo (CE 701–760), have an honorable origin and have been continuously handed down for generations since the eighth century in the Todaiji temple in Nara, Japan. Some of the beautiful artifacts found among the treasures display the bachiru carving technique, in which a delicate pattern is produced by carving dyed ivory or antler using additional painting. To elucidate the colorants used for dyeing and painting in the bachiru technique, non-invasive scientific analyses using fiber optic reflectance spectrometry in the visible region, X-ray fluorescence spectroscopy, and X-ray diffraction were performed for eight treasures: a go game board, two go pieces, a nyoi (ritual nail pole), a kugo harp, a bird-shaped accessory, a kaburaya arrow, and a ritual ruler. Second derivatization of the reflectance spectra led to characterization of the dyes in the treasures as sappanwood, lac, madder, gromwell, and indigo. Lac and atacamite were respectively identified in the red and green areas of the painting by reflectance spectrometry and X-ray diffractometry. These results indicated the use of a variety of colorants for the bachiru carving technique in the eighth century. 相似文献

目的：探讨茜草提取物对大强度耐力训练大鼠血清激素水平及运动能力的影响，为茜草作为运动补剂提供理论依据。方法：选取24只大鼠，随机分为安静组、运动力竭组和茜草力竭组，运动力竭组与茜草力竭组，参照Benfordt-1的训练模型进行6周的训练，最后一次训练进行一次力竭性运动，力竭后取血并进行样本处理。内容：利用FJ-2008P型全自动放射免疫分析仪，通过测定与运动训练相关的血清睾酮、皮质醇、胰岛素、胰高糖素、生长激素水平，研究茜草提取物对运动过程中机体的内分泌水平和大鼠跑台至力竭时间的影响。结论：茜草提取物运动中血清睾酮、皮质醇、胰岛素、胰高糖素、生长激素有一定的调节作用，揭示茜草在某种程度上可以改善运动造成的内分泌紊乱，提高大鼠跑台运动能力，从而延缓大鼠运动性疲劳的产生。 相似文献
