Abstract
嚴重的脊髓損傷常常導致在脊髓受傷部位以下的肌肉癱瘓無力以及感覺功能喪失,雖然甲基去氫氧化可體松(methylprednisolone,MP)是目前美國藥物食品檢驗局所核可治療急性脊髓損傷的藥物,然而其療效卻相當有限且有不少副作用。因此,發展出比MP更有效治療脊髓損傷的方法,是目前治療脊髓損傷的最重要課題。過去的研究報告指出在脊髓損傷發生後,男性患者的恢復情形比女性患者為佳。此外,研究也顯示雄性素具有保護受傷神經的作用。因為雄性素的作用一般被認為經由活化雄性素受體所達成。上述的研究結果引導我們提出雄性素受體 (androgen receptor) 在脊髓損傷上扮演著重要角色的假說。在本論文中,我們使用剔除雄性素受體(androgen receptor knockout, ARKO)的雄性小鼠以及同胎的正常雄性小鼠來檢驗上述的假說,我們於小鼠四個月大時為其施行脊髓損傷的手術,並觀察牠們在手術後後肢行動能力恢復的情形。我們的研究結果顯示,去除雄性素受體的雄性小鼠在脊髓損傷後,其後肢行動能力的恢復比起同胎具有雄性素受體的對照組雄性小鼠來的差。而剔除雄性素受體的雄性小鼠在脊髓損傷後顯示較大面積的脊髓損傷範圍及保留較少的軸突。我們的結果強烈支持,雄性素受體對脊髓損傷具有保護作用的論述。
