中文摘要：

背景：机体造血主要依靠造血祖细胞来扩增，当受到放射线、化学药物等损伤时，即会发生造血功能障碍。 目的：观察从传统中药鸡血藤中提取的九个单体化合物对骨髓抑制小鼠造血祖细胞增殖的影响。 设计：随机对照实验。 单位：中国人民解放军总医院临床药理研究室。 材料：实验于2002-11／2003-02在中国人民解放军总医院药理研究室完成，选用348只健康昆明种小鼠，体质量22～25g，清洁级，雌雄各半，由解放军军事医学科学院实验动物中心提供，许可证号码为SCXK-2001-001。实验过程中对动物的处置符合动物伦理学标准。鸡血藤由中国人民解放军总医院中药房提供，单体化合物没食子儿茶素、芒柄花素、儿茶素、焦性粘液酸、丁香酸、Demethylvestitol、间苯三酚、芒柄花甙、表儿茶素由中国医学科学院药物研究所从鸡血藤乙酸乙酯部位中分离。TGL-16型离心机为上海医疗器械六厂生产，CO2培养箱为日本SANYO公司产品，MK型倒置显微镜为日本OLYMPUS公司产品。 方法：①实验分组：随机抽签法将小鼠分为29组：鸡血藤九种单体化合物没食子儿茶素、芒柄花素、儿茶素、焦性粘液酸、丁香酸、Demethylvestitol、间苯三酚、芒柄花甙、表儿茶素高剂量组、中剂量组及低剂量组共27组，同时设立正常组及对照组，每组12只。②实验干预：除正常组外，小鼠均给予全身^60Co γ射线照射，剂量为4Gy。照射后第3天，9种单体化合物高、中、低剂量组小鼠分别腹腔注射2，0．4，0．08g/L相应单体化合物药液0．5mL，正常组和对照组小鼠腹腔注射等体积的生理盐水。③实验评估：给药30min后分别取正常组及对照组各8只及其他组全部小鼠静脉血制备正常、对照及各单体含药血清，取对照组剩余4只小鼠的骨髓细胞进行造血祖细胞培养，培养分为对照组和九个单体化?

英文摘要：

BACKGROUND： Hematogenesis of a body mainly depends on the proliferation of hematopoietic progenitor cell （HPC）. Hematopoietic functional impairment will occur when hematopoietic cells are injured by radioactive ray or chemical drug. The proliferation of HPC is the key link of promoting hematogenesis. OBJECTIVE： To study the effects of nine monomers extracted from Spatholobus suberectus Dunn （SSD） on proliferation of HPC in marrow-depressed mice. DESIGN： Randomized controlled trial. SETTING： Department of Pharmacy, General Hospital of Chinese PLA. MATERIALS： This experiment was conducted in the Department of Clinical Pharmacology, General Hospital of Chinese PLA from November 2002 to February 2003. Totally 348 healthy Kunming mice, weighing 22-25 g, clean grade, of irrespective gender, were selected in this study （certification： SCXK-2001-001）. The animal experiment was approved by the local ethics committee. SSD was provided by Dispensary of Traditional Chinese Medicine, General Hospital of Chinese PLA; monomers （gallocatechin, formononetin, catechin, pyromucic acid, syringic acid, Demethylvestitol, 1,3,5-benzenetriol, ononin, and epicatechin） were extracted from SSD acetoacetate; TGL-16 centrifuger was made in Shanghai 6th Medical Equipment Factory; CO2 incubator was made in SANYO Company, Japan; MK inverted microscope was provided by OLYMPUS Company, Japan. METHODS： Experimental grouping： Mice were randomly divided into 29 groups, including normal group; control group; gallocatechin high-, medium-, low-dose groups; formononetin high-, medium-, low-dose groups; catechin high-, medium-, low-dose groups; pyromucic acid high-, medium-, low-dose groups; syringic acid high-, medium-, low-dose groups; Demethylvestitol high-, medium-, low-dose groups; 1,3,5-benzenetriol high-, medium-, low-dose groups; ononin high-, medium-, low-dose groups; epicatechin high-, medium-, low-dose groups with 12 mice in each group. Experimental intervention： All the mice except the mice in normal grou
