The purpose of this paper is to report a newly discovered book whose title is Ikkam (翼鑑) and prepare for a full-scale study. The book, Ikkam, has a variety of contexts in which it seems to be written by Park Ji-won. First, 'Sanin' in 'Yeonam-Sanin' is consistent with the behaviors of Yeonam Park Ji-won who lived in hiding in the Yeonam valley in 1777. In addition, many statements written in the introduction, such as "as we stick to the old things, we do not know a makeshift", "we are well versed in changes" and "many soldiers are not always good" remind us of other writings of Park Ji-won. Moreover, he writes the statements using antithesis. It is the force of writing style of a literary person who is not engaged in medical service. In addition, he puts six qi in the introduction, but it is not as sophisticated as Jejungsinpyeon (濟衆新編). It suggests that this book may be published earlier than Jejungsinpyeon. When comparing Ikkam with Euimunbogam (醫門寶鑑) and Jejungsinpyeon, it seems common to place six qi in the introduction at the time. In addition, through this book, we find that Park Ji-won known as a writer of Geumryosocho (金蓼小抄) has fairly much knowledge in the medicine. We can estimate his passion and depth about the medicine through a longing for a new medical book shown in the introduction of Geumryosocho. However, various approaches to similar disease symptoms shown in the introduction help us to recognize his true qualities in the medicine. In addition, like other experience prescriptions, this book excludes prescriptions using medicinal herbs with toxicity or rare medicinal herbs in the situation with a limited supply of them in remote areas but includes prescriptions which are widely used. It shows that experience prescriptions in the Joseon Dynasty are effective to specifically identify medicinal herbs and prescriptions which are widely used in Korea. These values cannot be compensated by Donguibogam (東醫寶鑑) which has an infinite value.

Objectives : Jinnoe-san (JNS) is a novel herbal formula consisting of five oriental medicinal herbs including Polygalae Radix, Prunellae Spica, Perillae Herba, Betulae Cortex, and Lonicerae Flos. In this study, we investigated the effects and molecular mechanism of JNS on Parkinson's disease in vitro model. Methods : The effects of JNS on 1-methyl-4-phenylpyridinium ($MPP^+$)-induced cell death in SH-SY5Y cells were evaluated with a cell viability assay, flow cytometry, and western blots analysis. The effects of JNS on lipopolysaccharide (LPS)-stimulated BV2 microglia were determined with a nitric oxide (NO) assay, enzyme linked immunosorbent assays, and western blots analysis. Result : $MPP^+$-induced cell death in SH-SY5Y cells was significantly reduced by JNS pre-treatment in a dose-dependent manner. JNS inhibited the production of reactive oxygen species, mitochondria dysfunction, and apoptosis induced by $MPP^+$ in SH-SY5Y cells. Furthermore, JNS significantly activated Akt and ERK in SH-SY5Y cells and the ability of JNS to prevent mitochondria dysfunction by $MPP^+$ was antagonized by pre-treatment of LY294002 and PD98059, an Akt and ERK inhibitor, respectively. In addition, JNS inhibited LPS-induced NO and $PGE_2$ production as well as iNOS expression and secretion of TNF-${\alpha}$, pro-inflammatory cytokines without affecting the cell viability. JNS also suppressed LPS-induced ERK activation. Conclusions : These results demonstrate that JNS has a protective effect on the dopaminergic neurons against $MPP^+$-induced neurotoxicity and anti-inflammatory effect on the LPS-stimulated microglia. These findings provide evidences for JNS to be considered as a new prescription for treating Parkinson's disease.

Objectives : Noemyeong-san (NMS) is a novel herbal prescription composed of five oriental medicinal herbs including Prunellae Spica, Betulae Cortex, Foeniculi Fructus, Asiasari Radix, and Clematidis Radix for treating Alzheimer's disease. In the present study, we investigated the effects and molecular mechanisms of NMS on BV2 microglia to evaluate the potential action of this formula for preventing or treating neurodegenerative disease such as Alzheimer's disease. Methods : To determine the cytotoxicity of NMS on BV2 microglia, the MTT assay was performed. The effects of NMS on lipopolysaccharide (LPS)-stimulated BV2 microglia were determined with a nitric oxide (NO) assay and western blots for inflammatory mediator-related proteins, mitogen activated protein kinases (MAPKs), nuclear factor kappa B (NF-${\kappa}B$) pathway-related proteins, and heme oxygenase-1 (HO-1). Result : NMS inhibited induction of iNOS and COX-2 as well as NO production without affecting the cell viability in LPS-stimulated BV2 microglia. NMS also suppressed activation of ERK and p38 MAPK among main kinases of MAPKs as well as NF-${\kappa}B$ by LPS stimulation. Furthermore, NMS dose-dependently induced the expression of HO-1 and the inhibitory effect of NMS on the production of NO were blocked by pretreatment with an HO-1 inhibitor, Snpp. Conclusions : These results demonstrate that NMS has potent anti-neuroinflammatory effect on the LPS-stimulated microglia. These findings provide evidences for NMS to be considered as a new prescription for preventing or treating neurodegenerative disease such as Alzheimer's disease.

Objective : This study was carried out with focus on written by Joh, Taek-seung (曺澤承) and Joh, Byeong-who(曺秉矦) in the relation of father and son in 1933. This book is a medical book including rare data, which has never been reported to academic circles all this while. Method : First, this study looked into the authors of this book and its history of publication. Further, this study analyzed the composition and contents of this book. Lastly, this study summed up the meaning of this book from the standpoint of medical history. Result : The authors were Confucian doctors who were active in the latter era of the Joseon Dynasty and also in the period of Japanese colonial rule. They lived in Haenam district of Jeonlanam-do, and cured its neighboring local residents while studying. They published the book of by putting together their own medical experiences. The authors suggested their remedial prescription according to gender and age whereas Zhang Zhongjing(張仲景) suggested the remedial prescription according to Six-Meridian Pattern Identification & Syndrome Differentiation(六經辨證). In addition, the authors of gave weight to the relationship with internal damage. Additionally, the authors not only thought much of the relationship between internal damage and external damage but also thought of the weakness and strength of the healthy qi, and the new and the old of a disease as an important clue to medical treatment. It seems that such contents was influenced by (東醫寶鑑). Conclusion : shows the results of the research on which was spontaneously conducted in Joseon.

Objectives Rehmanniae Radix Preparata was prepared in the traditional Rehmanniae Radix Preparata preparation method set forth in the 『Treasured Mirror of Eastern Medicine(Donguibogam)』 with a view to measuring the contents of 5-Hydroxymethyl-2-furaldehyde(5-HMF) at individual stages of steaming and sundrying and identifying new chemical components.Methods Based on the traditional Rehmanniae Radix Preparata preparation method set forth in the 『Treasured Mirror of Eastern Medicine』, Rehmanniae Radix Preparata steamed and sundried once through nine times was prepared. Thereafter, 5-HMF contents were analyzed and new chemical components were identified in the Rehmanniae Radix Preparata using Waters HPLC e2695, 2640 detectors, a Waters Acquity UPLC system, and a Micromass Q-TOF Premier mass spectrometer.Results The Rehmanniae Radix Preparata preparation method set forth in the 『Treasured Mirror of Eastern Medicine』 is a unique preparation method in Republic of Korea different from that in China. In the first stage of the method, fresh Rehmanniae Radix Crudus was divided into high quality, medium quality, and low quality ones named Rehmanniae Radix Crudus (Caelum)(天黃), Rehmanniae Radix Crudus (Homo)(人黃), and Rehmanniae Radix Crudus (Terra)(地黃) respectively to use Rehmanniae Radix Crudus (Caelum) and Rehmanniae Radix Crudus (Homo) for preparation of juice while using Rehmanniae Radix Crudus (Terra) to make Rehmanniae Radix Preparata. In the second stage, Rehmanniae Radix Crudus (Caelum) and Rehmanniae Radix Crudus (Terra) were made into juice and Rehmanniae Radix Crudus (Terra) was soaked in the juice. In the third stage, among auxiliary materials, rice wine named Purum Vinum Oryzae(淸酒) brewed from sticky rice was sprinkled on Rehmanniae Radix Crudus (Terra) to the extent that Rehmanniae Radix Crudus (Terra) became wet. In the fourth stage, Rehmanniae Radix Preparata steamed in earthenware steamer was dried under natural sunlight. The contents of 5-HMF in Rehmanniae Radix Preparata steamed and sundried once through nine times were shown to be below 0.1% in all cases. Pomolic acid was identified as a new chemical component.Conclusions In conclusion, the Rehmanniae Radix Preparata preparation method set forth in the 『Treasured Mirror of Eastern Medicine』 is thought to be a unique preparation method in South Korea in which Rehmanniae Radix Preparata is completed through the first stage in which fresh Rehmanniae Radix Crudus collected from fields is divided into high, medium, and low quality ones and fresh Rehmanniae Radix Crudus juice is made, the second stage in which the high quality fresh Rehmanniae Radix Crudus is soaked in the fresh Rehmanniae Radix Crudus juice, the third stage in which the fresh Rehmanniae Radix Crudus is steamed, and the fourth stage in which the steamed Rehmanniae Radix Crudus is dried.

Recently, 『Gyeongja(庚子)/Daetongryeok(大統曆)』(1600), a memorandum record of Yu Seong-ryong during the reign of King Seonjo(宣祖) of the Joseon Dynasty, was returned to Korea from Japan, and about 4,000 letters in cursive characters have been interpreted by Ro Seung-suk. The contents for 203 days written in the margin of 『Gyeongja(庚子)/Daetongryeok(大統曆)』 are mostly new, and are meaningful in understanding Yu's life and social association circumstances. There are daily routines of each day, contemporary figures, diseases and oriental medicine prescriptions. In particular, the combat record of Admiral Yi Sun-shin in 83 letters on the cover is very important to understand the situation in those days. It seems that the reason for writing the combat situations a year and a few months after Admiral Yi died in war was to honor his distinguished military service for a long time by King Seonjo's order according to the public opinion of the royal court. The record can be classified into two categories. First, Admiral Yi sighed when he heard about Yu's dismissal from the office in Gogeumdo, and was always alert with clear water on the boat after the Battle of Waekyo Castle. Second, he was killed by bullets shot by the enemy while directly encouraging battle, not listening to his men who tried to dissuade him from leading the naval battle at Noryang. This only contained contents of devoting his life desperately, which is an important proof of the theory of his death in war. It also contains nine methods for making liquor and another method that wasn't known to the public, and seems to include popular alcohol brewing methods or newly devised ones. In addition, there is a detail that Heo Jun, the author of 『Donguibogam』, introduced medicine to Yu, along with being unable to attend ancestral rites and relieving the poor written in red. There are also stories about Kang Hang(姜沆) returning to Korea after being captured by Japan and Lee Deok-hong(李德弘)'s son, who introduced Gugapseondo(龜甲船圖, the first picture of the Turtle Ship in Korea) to King Seonjo. In the light of the above, 『Gyeongja(庚子)/Daetongryeok(大統曆)』is an important historical record to empirically research not only figures related to Yu but also the circumstances of those days since it contains new facts that are not in the existing literature. In particular, the big accomplishment of this study is to correct the mistakenly known theory of Admiral Yi's suicide and to find out the new fact that Heo Jun provided medical information. In this respect, this book is expected to serve as a testament to the future study of the history and characters related to Yu in the mid-Joseon period.
