Abstract
鉛蓄積於人體會誘發氧化性壓力,造成嚴重的發炎反應,導致許多組織與器官受損,進而影響生物體正常的生長發育,嚴重甚至可能導致死亡。鉛中毒的臨床治療,目前主要使用熬合劑或洗胃來清除循環與消化系統中殘餘的鉛,但這些治療方式無法有效的降低蓄積於組織或器官中的鉛。過去文獻指出遠紅外線(非一般的三溫暖或運動),可促進鉛經由汗液排出,遠紅外線因此被認為可能有助於加速鉛的排除,或許在治療及預防鉛中毒方面可以發揮作用。本篇論文利用特定波長(9~14μm)之遠紅外線照射皮膚角質細胞( HaCaT ),在未通電且沒有明顯溫度變化的情況下,證實遠紅外線確實可以加速傷口癒合。細胞實驗中我們發現,鉛會誘導細胞內的氧化性壓力(R.O.S.)上升導致腎臟細胞死亡,而遠紅外線處理組,細胞內鉛含量與氧化性壓力相對較低。在動物實驗中,老鼠持續飲用鉛水(3g/500ml)七週,之後將之分為兩組,一組不做任何處理(鉛單獨處理組),另一組則定時給予遠紅外線照射,量測老鼠血液及尿液中鉛濃度後發現,鉛單獨處理組血中鉛濃度(71μg/ml)明顯高於遠紅外線治療組(30μg/ml)。此外,鉛所造成的老鼠體重減輕與腎絲球病變,在遠紅外線治療組明顯比鉛單獨處理組少。我們的研究結果顯示遠紅外線或許可以透過加速鉛代謝,降低鉛的蓄積與所誘導的氧化性壓力,降低鉛對腎臟造成的傷害。
