Abstract
慢性肝病及肝硬化為國人101年十大死亡原因之第九位,造成肝臟疾病主因有病毒性、酒精性與化學性三大類;其中化學性肝損傷於動物試驗模式之病理切片與人體有一致之病理現象。本試驗係依照行政院衛生署公告之健康食品之護肝功效評估方法(針對化學性肝損傷),探討庫拉索蘆薈葉肉對四氯化碳(carbon tetrachloride,CCl4)所誘導之Sprague-Dawley (SD) 大鼠肝臟慢性損傷的影響。試驗物質為冷凍乾燥後的蘆薈葉肉粉末,試驗動物共分為六組:正常控制組、正負對照組與低、中、高劑量試驗組 (200, 600, 1200 mg/kg)。正常控制組給予Olive oil,正對照組給予Silymarin,負對照組未給予任何物質;除正常控制組外,五個組別每週兩次以管餵給予CCl4持續8週。結果顯示低劑量試驗組對CCl4誘發慢性肝炎的血漿ALT、AST有顯著降低作用。高劑量試驗組對肝臟纖維化的指標,例如肝纖維化病理評分結果、肝臟中hydroxyproline含量皆有明顯降低作用。此外三組劑量組皆能提升大鼠肝臟中catalase, glutathione peroxidase 以及glutathione reductase等抗氧化酵素之含量,但不能提升glutathione與superoxidase dismutase含量。由上述結果顯示,給予大鼠凍乾蘆薈葉肉粉末,可經由增加肝臟抗氧化酵素含量、減少肝組織纖維化發生以及降低血漿AST、ALT值,達到減輕CCl4所誘發之大鼠肝臟慢性損傷的效果。
