1、乳香沒藥對大鼠肝臟毒性的比較研究周昆1,談英2,柳占彪1,張躍飛2,胡利民1,高秀梅1(1.天津中醫(yī)藥大學(xué)中醫(yī)藥研究院,天津市中藥藥理重點實驗室,天津300193;2.三九醫(yī)藥股份有限公司研發(fā)事業(yè)部,深圳518029)摘要:目的比較乳香和沒藥對大鼠的肝臟毒性。方法48只Wistar大鼠隨機分為4組,分別為對照組、乳香沒藥(1:1)組、乳香組、沒藥組,各給藥組劑量均為2.1g/kg,連續(xù)灌胃給藥12周。禁食12小時后水合氯醛麻醉動物,取血檢測血清生化指標(biāo),并解剖稱取肝臟濕重計算肝臟系數(shù),并測定肝組織中
2、MDA,光鏡下對肝臟進行病理組織學(xué)檢查。結(jié)果乳香沒藥組和乳香組大鼠的血清TC和肝組織中MDA明顯高于對照組(P<0.05)。給藥組大鼠肝系數(shù)均明顯升高(P<0.01),肝系數(shù)乳香組>乳香沒藥組>沒藥組。肝臟病理組織學(xué)檢查表明,乳香組2只大鼠肝臟中度脂肪變性而乳香沒藥組和沒藥組則未見明顯異常。結(jié)論乳香對大鼠的肝臟毒性強于沒藥。關(guān)鍵詞:乳香;沒藥;肝毒性ComparativestudyonhepatotoxicityofOlibanumandMyrrhainratsZHOUKun1,TANYing2,L
