【摘要】:腦缺血/再灌注損傷及高血壓均是常見(jiàn)的心腦血管疾病,中藥復(fù)方從多靶點(diǎn)、多向調(diào)節(jié)出發(fā)對(duì)心腦血管疾病起保護(hù)作用。圣腦康丸(SNKP)由丹參、川芎等15味中藥組成,具有活血化瘀、涼血降壓等功效,臨床用于急、慢性心腦血管病的治療,目前尚未有SNKP對(duì)腦缺血/再灌注損傷保護(hù)及降壓的實(shí)驗(yàn)研究報(bào)道。 本實(shí)驗(yàn)采用HPLC法同時(shí)測(cè)定了SNKP中丹參素、原兒茶醛、芍藥苷、葛根素、阿魏酸、丹參酮ⅡA6種有效成分的含量,甲醇-0.25%冰醋酸水溶液為流動(dòng)相梯度洗脫,檢測(cè)波長(zhǎng)為280nm,方法簡(jiǎn)便、準(zhǔn)確、靈敏。 采用線栓法制作大鼠局灶性腦缺血/再灌注損傷模型和小鼠常壓耐缺氧實(shí)驗(yàn),研究了SNKP對(duì)腦缺血缺氧的保護(hù)作用。通過(guò)大鼠神經(jīng)功能評(píng)分、TIC染色、HE染色法等方法進(jìn)行綜合評(píng)價(jià);同時(shí)測(cè)定大鼠血清或組織中MDA、SOD、GSH-Px、iNOS、Caspase-3等相關(guān)指標(biāo)活性,觀察小鼠常壓耐缺氧時(shí)間,結(jié)果表明SNKP能明顯改善神經(jīng)功能障礙,減少大腦梗死體積,增加存活的神經(jīng)元數(shù)量,降低MDA含量,增強(qiáng)SOD、GSH-Px活性,降低iNOS及TNOS活性,減少Caspase-3活性細(xì)胞數(shù)目。說(shuō)明SNKP對(duì)腦缺血/再灌注損傷有保護(hù)作用,其保護(hù)機(jī)制可能與其抗氧化、抗凋亡與降低iNOS和TNOS活性等有關(guān)。SNKP能有效提高常壓下及異丙腎上腺素聯(lián)合給藥的耐缺氧時(shí)間,具有明顯的耐缺氧作用。 利用自發(fā)性高血壓大鼠研究了SNKP的降壓作用。采用無(wú)創(chuàng)血壓測(cè)量分析系統(tǒng)測(cè)量血壓及心率,采用全自動(dòng)生化分析儀測(cè)定血脂、腎功能等相關(guān)的生化指標(biāo),并測(cè)量了各臟器指數(shù)、左心室指數(shù)等,結(jié)果表明SNKP能有效平穩(wěn)的降低血壓,調(diào)節(jié)心率,降低左心室指數(shù),改善腎功、血脂等生化指標(biāo),恢復(fù)對(duì)主要器官(心、腦、腎等)的損傷。 因此,SNKP對(duì)大鼠腦缺血/再灌注損傷有保護(hù)作用,對(duì)自發(fā)性高血壓大鼠有降壓作用,并能有效延長(zhǎng)小鼠的常壓耐缺氧時(shí)間,為心腦血管疾病的治療提供了理論基礎(chǔ)。
