The Medical records (醫案) are very important materials in studying the developmental process of traditional Korean medicine. In this study, we investigated the medical records which are described in Naekyung-pyun(內景篇) of Dongeuibogam(東醫寶鑑), the most famous medical literature in Korean. There are 50 medical records in Naekyung-pyun and all of these records are cited from 12 Chinese medical literatures. The medical records were mainly cited from medical literatures written in Jin-Yuan(金元) and Ming(明) dynasty such as Yixuegangmu(醫學綱目) and Danxizanyao(丹溪纂要), although most records were written by medical scholars in Jin-Yuan(金元) dynasty, including Zhudanxi(朱丹溪) and Zhangzihe(張子和). Most of records were omitted and/or modified reflecting the Purpose of editors of Dongeuibogam. In addition, medical essay(醫論) was changed into medical record in some cases. The authors of the records used oral medication, acupuncture-moxa, psychological treatment and surgical manners. And in some cases of only having principal of treatment, the editors newly added the herbal prescription. The further study on medical records in Korean traditional medicinal literatures, would reveal the developmental progress of Korean medicine and inform more actual proof on medical condition.
