肌肉持续剧烈收缩诱发大量活性氧的产生。我们发现经典的活性氧清除剂和具活性氧清除能力的天然产物 ,都可以延缓离体肌肉收缩疲劳。维生素Ｃ(Ｖｃ)是体内重要的活性氧清除剂。本文旨在探讨Ｖｃ对离体肌肉收缩的影响。1 材料和方法健康的中华大蟾蜍 ,体重 70～ 10 0 ｇ。按体?
Severe persistent muscle contraction induced a large number of reactive oxygen species. We found that classic reactive oxygen species scavengers and natural products with active oxygen scavenging capacity can delay muscle contraction fatigue in vitro. Vitamin C (Vc) is an important reactive oxygen species scavenger in the body. This article aims to investigate the impact of Vc on isolated muscle contraction. 1 Materials and methods Healthy Toad, weighing 70 ~ 100 g. According to body?
