本实验旨在研究β-七叶皂甙钠在大白鼠腹部岛状皮瓣中的抗氧自由基功能，为其在颌面及成形外科的临床应用提供实验依据。一、材料与方法将大白鼠随机分为３组，按Ｈａ－ｒａｓｈｉｎａ的方法，在大白鼠右下腹设计一面积为３ｃｍ×６ｃｍ岛状皮瓣，第一、二组皮瓣血流阻断７小时
The purpose of this experiment is to study the anti-oxygen free radical function of sodium aescinate in the island flap of the abdomen of the white rat, providing experimental basis for its clinical application in maxillofacial surgery and plastic surgery. Materials and Methods The rats were randomly divided into three groups. According to the method of Ha-rashina, a 3 cm × 6 cm island flap was designed on the right lower quadrant of the rats, and the first and second groups were blocked by blood flow hour
