Abstract
在我們先前的研究,D-乳酸可能可作為腎損傷的指標,且其前驅物甲基乙二醛(Methylglyoxal ; MG)也為高度氧化壓力的產物,所以本次研究目的在於利用gentamicin(GM)誘導的腎損傷,並給予最近許多文獻報導指出對腎臟具保護效果的atorvastatin(ATO),觀察其腎、
血清、尿中,D-乳酸及甲基乙二醛之間的變化。
本次動物實驗利用Male Wistar Albino rats (340–350 g) 24隻隨機分為4組,每組6隻。組別分別為Normal組、GM誘導組、GM+ATO給藥組及ATO組,並在給藥後10日予以犧牲,觀察其結果。
在結果方面,在腎臟及血清中可觀察到D-lactate及MG在GM誘導組和Normal組相比,皆有明顯的上升(P < 0.01),而GM+ATO的給藥組和GM誘導組相比則可看到D-lactate及MG有下降的效果(P < 0.05)。在尿中MG方面在在誘導後第8天(Day 8)則可觀察到GM誘導組和正常組相比,有上升的效果(P < 0.05)而GM+ATO的治療組和GM誘導組相比則可看到尿中MG有下降的效果(P < 0.05);在尿中D-乳酸方面在誘導後第4天(Day 4) GM誘導組和Normal組相比反而呈現下降的趨勢(P < 0.05),在誘導後第8天(Day 8) GM誘導組雖有微升但和Normal組相比還是呈現下降的結果(P < 0.05)。



所以本次研究可觀察到腎功能的好壞和血中及腎臟中D-lactate具高度相關性,代表D-乳酸對於GM誘導腎病變也有高度的相關性,且D-乳酸前驅物甲基乙二醛也隨著腎病變的進程在腎臟、血清、尿中呈現上升的趨勢,此外ATO對GM造成的腎損傷也有達到改善的效果,但在尿中D-乳酸GM誘導組和Normal組相比反而有下降的趨勢,代表著D-lactate在腎臟有累積,但排除到尿液的量反而較少,很有可能由於腎臟中對於D-lactate再吸收作用受到影響,造成此結果的原因還需做進一步的確認。
