第三節 結論
在體外試驗中,五苓散萃取液有抑制草酸鈣結晶形成的效用,是經 由抑制草酸鈣結晶核心的形成以及抑制結晶顆粒間相互的聚集。在動 物試驗中,五苓散能有效抑制鼠腎小管中草酸鈣結晶的沉積。因此,
五苓散有潛在的能力可以預防草酸鈣結石的發生,這結果可由進一步 的臨床應用來證實。
本研究亦建立了良好的實驗平台和動物模式來篩選具抗結石功效 的中草藥,期望為預防尿路結石做出重大的貢獻。

Wu-Ling-San Formula Inhibits the Crystallization of Calcium Oxalate in vitro and in rats
Graduate student:Yu-Cheng Chen Major professor:Sheng-Feng Hsu
Graduate institute of Chinese Medical Science, China Medical University
Urinary stone disease is a common and high-recurrent disease.
There is no ideal medical drug to prevent the recurrence of urinary stone. Therefore, to develop effective medical drugs is a worthwhile issue. The purpose of this study was to investigate the effect of Wu-Ling-San(WLS)on calcium oxalate formation by using crystallization experiments of crystal nucleation, growth, and aggregation in vitro. Then the animal study was followed to investigate the effect of WLS on EG(ethylene glycol)-induced nephrolithiasic rats. The results of crystallization experiments indicated that WLS extract exerted an effect in the inhibition of calcium oxalate crystallization by inhibiting the nucleation and aggregation. The results of animal study revealed WLS could inhibit calcium oxalate crystal deposition effectively in renal tubules of rats fed by EG. Therefore, it may have potential for preventing stone recurrence if further clinical study can be confirmed.
Key word:Urinary stone, Wu-Ling-San formula, Calcium oxalate
謝 辭
當初秉持著要以科學化的方法來證實中醫效用的信念,進而來到中 國醫學研究所學習,想要努力證明中醫並不是怪力亂神或是不科學,而 是數千年來老祖宗寶貴的智慧結晶。現今中國醫學慢慢已經在國外有發 揚光大的趨勢,但在國內仍被少數人視如敝屣,實為痛心,在此希望盡 自己一份棉薄心力來延續和發展中國醫學,期望付予嶄新的面貌。
兩年時間匆匆過去,在研究所的老師和前輩的教導下,獲得了許多 有用的知識和觀念,也對於中醫科學研究開始跨出了第一步,這一步雖 然很辛苦,但是回首起來真的很充實,收穫真的很多。然而兩年所能達 到的成果不多,而今後要走的路還很長遠,仍然希望往後有機會和前輩 及有志者一同努力。
父親十餘年來身體一直不是很好,在今年一月間辭世。自己未能把 此成果親自呈獻給他,心中不免有些遺憾。非常感謝父親二十幾年來辛 苦培育之恩,讓我衣食無虞能夠好好的學習醫學,才能夠達到目前的成 就,您的恩情浩瀚,實是無以回報。也感謝母親辛勞的撫養之恩,誠心 希望您未來的日子能夠健康快樂。也非常謝謝關心我、幫助我的伯伯、
叔叔、姑姑等長輩們。
兩年來,經由許多人的幫助,我才能順利的完成學業,在此由衷感 激你們:感謝陳汶吉教授的用心指導實驗進行和論文寫作,讓我獲益匪 淺;感謝陳悅生教授在論文寫作上的指導;感謝許昇峰教授指導論文寫 作以及在澄清中醫科工作上的協助;感謝賴銘淙老師在病理切片上的詳 細教導;感謝澄清中醫科的所有同仁在這兩年來愉快的相處和協助,讓 我獲得非常寶貴的臨床經驗;感謝秀雯給予多方面的支持與幫助;感謝 寧漪姊的大力幫忙;感謝凱揚、承志兩位學弟實驗上的協助;感謝李佳 霖同學在統計方面的友情指導;感謝蔡輔仁院長實驗室的同仁們在各方 面的協助;感謝所有研究所的老師和同學,讓我擁有美好、充實的兩年 碩士研究生涯。
