Abstract
馬兜鈴酸 (aristolochic acid, AA) 在中草藥引起的腎病變中扮演重要的角色。本研究的目的為藉由投予AA引起馬兜鈴酸腎病變 (aristolochic acid nephropathy, AAN),以評估人參 (ginseng extrat, GE) 及其成份ginsenoside Rb1、Rd及Rg1對AAN的改善效果。
給予純系小鼠C3H/He (6 week-old male) 3.0 μg/mL AA當飲用水,連續56天,之後治療組分別經口投予GE (125、250、500 mg/kg)或純成份ginsenoside (Rb1、Rd、Rg1) 5 mg/kg連續14天,對照組給予等量蒸餾水,Normal組則全程給予蒸餾水。
藉由測定尿蛋白,尿中N-acetyl-beta-D-glucosaminidase (NAG) 與血中blood urea nitrogen (BUN) 及creatinine,以評估小鼠腎功能;腎組織使用PAS染色觀察病理組織改變,並進行免疫螢光染色 (TGF-β,MMP-9,HGF),以辨識損傷部位之特異性抗原。
實驗結果顯示,投予GE 250 mg/kg,ginsenoside Rb1, Rg1之治療組的尿蛋白、NAG、BUN、SCr及血糖值都有降低;組織學及免疫螢光染色觀察發現腎組織損傷的情形皆有緩解。根據以上結果發現,人參濃縮劑部分,GE 250的療效最好,其次依序為GE 500 及GE 125。人參皂苷部分,有效程度依序為Rg1、Rb1、Rd。
