Abstract
肥胖在許多研究中指出與腎臟損傷及其發展成腎臟相關疾病有極大關聯,而其可能機制包含血脂升高及腎臟脂質累積所造成的脂毒性、氧化壓力、高血壓及腎臟超過濾作用等有關,進而造成腎臟粒線體功能缺失,導致腎臟功能的損傷。而過去研究指出山竹果殼中富有的活性成分具降低氧化壓力、改善肥胖及改善腎損傷等功效,因此本次研究利用山竹果殼粉,探討其對於高脂高膽固醇飼料誘發大鼠腎臟損傷及對於腎臟粒線體功能的影響。本次實驗以六週齡雄性SD大鼠分為四組:控制組、高脂高膽固醇飼料組、高脂高膽固醇飼料同時添加低劑量、高劑量山竹果殼粉組。控制組飼料給予AIN93G之配方,其中含有熱量百分比15.9%的脂肪,脂肪來源主要為大豆油;高脂高膽固醇飼料組飼料給予含有熱量百分比50.9%的脂肪,脂肪來源主要為豬油,並添加1%膽固醇。高脂高膽固醇飼料同時添加低劑量及高劑量山竹果殼粉組則分別給予含有飼料重2.5%及5%的山竹果殼粉於飼料之中。實驗二十週後發現在低劑量山竹果殼粉的介入後,能改善高脂高膽固醇飼料所增加血膽固醇且血液肌酸酐及廓清率降低,並增加抗氧化酵素過氧化氫酶活性,與顯著降低血管收縮素濃度及第四型NADPH氧化酶,並增加粒線體呼吸控制比值之情形。根據上述結果顯示,長期高脂高膽固醇飼料造成的肥胖及腎臟損傷可能藉由促使血脂增加、過度活化腎素-血管收縮素系統且粒線體功能降低,促使氧化壓力增加,而在給予山竹果殼粉的介入則能改善肥胖所造成的氧化壓力、腎臟損傷。
