1、玉郎傘水提物對(duì)大鼠的長(zhǎng)期毒性研究施之陳春霞黃仁彬(通訊作者)(廣西醫(yī)科大學(xué)藥學(xué)院廣西南寧530021)【摘要】目的:觀察玉郎傘水提物對(duì)大鼠的長(zhǎng)期毒性,為臨床安全用藥提供依據(jù)。方法:80只Wistar大鼠(雌雄各半)隨機(jī)等分為對(duì)照組和玉郎傘水提物低、中、高劑量組(20、40、80g生藥?kg-l?d-l,相當(dāng)于人臨床日擬用量的20、40、80倍),連續(xù)灌胃給藥91天,停藥后觀察14天,對(duì)照組給以等體積蒸憾水。給藥期及停藥恢復(fù)期,觀察大鼠的體征、行為、攝食量、排泄等一般狀況,及血液學(xué)、血液?;笜?biāo)、臟體系數(shù)
2、、病理組織學(xué)變化等。結(jié)果:玉郎傘水提物對(duì)大鼠的一般狀況、體質(zhì)量增長(zhǎng)、攝食量、血液學(xué)、血液?;笜?biāo)、臟體系數(shù)、病理組織學(xué)變化無(wú)明顯影響。結(jié)論:在本試驗(yàn)條件下,玉郎傘水提物在2080g牛藥?kg-l?d-l屬于安全劑量范圍?!娟P(guān)鍵詞】玉郎傘;水提物;大鼠;長(zhǎng)期毒性【中圖分類號(hào)】R965【文獻(xiàn)標(biāo)識(shí)碼】A【文章編號(hào)】2095-1752(2015)08-0020-04StudyonChronicToxicityofWaterExtractfromYulangsaninratsShiZhi,ChenCunxia,H

8、;ChronicToxicity玉郎傘是蝶形花科植物疏葉崖豆的干燥塊根,又名龍眼參、大羅傘、土甘草等,主要分布于廣西、廣東地區(qū),廣西民間將其用于治療氣血兩虛,失眠,小兒疳積、跌打損傷、中風(fēng)性偏癱等常見(jiàn)疾病,近年來(lái),本課題組針對(duì)玉郎傘有效成分的作用做了較廣泛而深入的研究,前期研究表明玉郎傘具有保肝、益智、降血壓、抗應(yīng)激、清除氧自由基以及化療增敏等作用,具有潛在的廣泛應(yīng)用前景。故本實(shí)驗(yàn)用玉郎傘水提物對(duì)大鼠進(jìn)行91天的灌胃給藥及14天恢復(fù)期觀察,
