〔記者楊媛婷/台北報導〕禿頭這次真的有救,不用再拔獅子的鬃毛了。由科技部、台大
醫院、台灣生技醫藥發展基金會支持,台大醫院皮膚部主任林頌然領導的團隊與美國哈佛
大學跨國研究發現生髮密碼,寒冷、受到驚嚇、感動等,都會刺激豎毛肌收縮產生雞皮疙
瘩,提升毛囊幹細胞活性,能加速毛髮再生,也發現神經突觸構造可以調控體內的幹細胞
,該研究今天登上國際一級期刊《Cell》(細胞)。
林頌然指出,動物遇到危險,毛髮都會豎立來威嚇敵方,人類在演化過程裡,隨著體毛逐
漸減少或消失,過往豎毛的保護機制轉為「雞皮疙瘩」的模式呈現,他指出當交感神經高
度活化時,會刺激豎毛肌收縮產生雞皮疙瘩,並且毛囊幹細胞活性也會被提升,加速毛髮
再生,他進一步補充,交感神經可降低豎毛肌的休眠表現,並更容易活化毛囊幹細胞,也
就是說如果毛囊失去豎毛肌,交感神經會從毛囊附近退開,如果沒有豎毛肌,毛囊幹細胞
將進入深度休眠,並使毛髮停止生長。
林頌然提醒,由於刺激交感神經與豎毛肌都必須長達數天,民眾絕不可誤以為只要長期待
在寒冷的室內、常看恐怖片等,就能透過刺激交感神經與豎毛肌來避免禿頭,他強調如果
是全面刺激交感神經容易造成身體健康的風險,林頌然表示,目前已透過藥物進行動物實
驗,並已成功活化實驗鼠的毛囊以及培養的人類毛囊幹細胞,未來經過人體試驗後,最快
6年就會有新的生髮藥物面世。
3.心得/評論:
生技元年?
感覺每隔一段時間就有這種給禿頭仔一線希望的新聞
但是,6年又6年
禿頭仔要嘛希望落空要嘛就是副作用變陽痿仔
