1、黃芩苷對缺血性腦損傷雄性大鼠腦保護作用的機制研究摘要:H的觀察黃芩苷對缺血性腦損傷雄性大藏的腦保護作用及其對大鼠血清孕酮水平的影響,探討其可能的作用機制。方法采用成年SD雄性大鼠制造永久性左側大腦中動脈梗阻模型,根據(jù)神經(jīng)功能評分,分為模型組、黃芩苷組和抑制劑組,假手術組不插入拴線。造模后于不同時間點進行神經(jīng)功能評分及雙前肢抓力測定,計算抓力下降率;ELISA檢測血清孕酮和促腎上腺皮質(zhì)激素(ACTH)含量。結果與假手術組比較,模型組大鼠神經(jīng)功能受損,雙前肢抓力顯著減小。治療7d后,與模型組比較,黃芩苷組神經(jīng)功能評分降低,雙前肢抓力恢復,
2、抓力下降率減?。≒〈0.05);與黃芩苷組比較,抑制劑組黃芩苷神經(jīng)功能保護作用降低(P〈0.05)。治療7d后,與模型組比較,黃芩苷組血清孕酮水平顯著升高(P〈0.01),ACTH水平有升高趨勢;與黃芩苷組比較,抑制劑組血清孕酮和ACTH水平均降低(P〈0.05)。結論黃芩苷對缺血性腦損傷雄性大鼠的腦保護作用可能與其調(diào)控孕酮生成有關。本文采集自網(wǎng)絡,本站發(fā)布的論文均是優(yōu)質(zhì)論文,供學習和研究使用,文中立場與本網(wǎng)站無關,版權和著作權歸原作者所右,如存不愿意被轉載的情況,請通知我們刪除己轉載的信息,如果需要分享,請保留本段說明。關鍵詞:黃芩
