Objective : The purpose of this study is to extend indications of Four-Constitution Medicinal formulas by comparing with formulas on Dongeuibogam(東醫寶鑑), focusing on their composition. Method : 1. We analyzed the composition of Sanghan formulas(傷寒方) and non-classical formulas(後世方) which are mentioned on Donguisusebowon(東醫壽世保元), focusing on their composition. 2. We analyzed the composition of formulas on Dongeuibogam(東醫寶鑑) comparing with Bojungyikgi-tang for So-Eum type. Result & Conclusion: 1. Je-Ma Lee didn't say the Sanghan formulas(傷寒方) and non-classical formulas(後世方) with criterion of composition on his book. 2. We finally selected one formulas(Insamhwanggi-tang) and its effect as similar formulas with Bojungyikgi-tang for So-Eum type.

Armeniacae Semen not only contains amygdalin, but emulsin also, which is an enzyme that hydrolyzes amygdalin. The extraction yield of amygdalin from Armeniacae Semen was low, due to the presence of emulsin, when extracted with water. When Schizandrae Fructus solution was used as the extractant; however, amygdalin was almost completely extracted, regardless of the cutting size, due to the absence of the influence of emulsin. In addition, when the crude powder or small piece forms were used with Schizandrae Fructus solution, on epimerization of the D-amygdalin into neoamygdalin occurred. D-amygdalin and its conversion product, neoamygdalin, were quantitatively analyzed by reverse-phase, high-performance liquid chromatography (HPLC), with an optimized eluent of 10 mM sodium phosphate buffer (pH 2.3), containing 11.5% acetonitrile. The concentration and detector response were linearly correlated over the range 0.05 to 2 mM. The detection limits for both D-amygdalin and neoamygdalin were approximately $5\;{\mu}M$ for the amount injected.

Homosyringaldehyde was isolated and identified from the 80% methanol extract of roots of Cynanchum paniculatum. C. paniculatum has been widely used for the treatment of various diseases such as neurasthenia, insomnia, dysmenorrheal and toothache. This compound exerted significant neuroprotective activities against glutamate-induced neurotoxicity in hippocampal HT22 cell line by 37.53% (at the concentration of $100{\mu}M$). We investigated mode of action of this compound. Homosyringaldehyde ($100{\mu}M$) significantly decreased the ROS level and $Ca^{2+}$ concentration in the oxidative stress induced HT22 cells by oxidative glutamate toxicity. Thus, our results suggest that homosyringaldehyde significantly protect HT22 cells against glutamate-induced oxidative stress, via antioxidative activities. As the results, we suggest that homosyringaldehyde may be useful in the treatment of neurogenerative disorders.

Objectives : Alpiniae oxyphyllae Fructus (AOF) is an herbal medicine, which has been used for the treatment of fatigue, chills, and poor physical conditions. The objective of this study was to investigate the anti-inflammatory and anti-oxidative effects of AOF hot aqueous extract. Methods : The cytotoxicity of AOF extract was evaluated using the MTT assay. Nitric oxide (NO) production was measured by the Griess reaction. Prostaglandin $E_2$ ($PGE_2$) production was measured by a commercial competitive enzyme immunoassay. Cytokine production (IL-1tion co6, and TNF- F- was measured by ELISA. The anti-oxidative effect of AOF extracts was measured by the DPPH method. Polyphenol and flavonoid contents were measured by Folin-Ciocalteu's phenol reagent and aluminum chloride, respectively. Results : AOF hot aqueous extract did not show toxicity at doses of 25, 50, 100, and $200{\mu}g/mL$. AOF extract significantly inhibited NO production at doses of 100 and $200{\mu}g/mL.PGE_2$ production was inhibited by AOF extract treatment at doses of 100 and $200{\mu}g/mL$. AOF extracts reduced IL-6 production in a dose-dependent manner. IL-1ent maTNF- F- 1ent mannerd IL-6 production in uction at doses of 100 and ${\mu}g/mL$. The DPPH free radical scavenging capability was above 50% at $200{\mu}g/mL$. Conclusion : This study suggests that AOF hot aqueous extract may exert anti-inflammatory and anti-oxidative effects in a dose-dependent manner. Further studies are required for validating the safety and efficacy of AOF.

1. Purpose of study In Sasang Constitutional Medicine, human's physiology and pathology are caused by Sung-Jung that joy, anger, sorrow, and pleasure' expression. So, the purpose of this study is to investigate the correlation between Sung-Jung in and Sung-Jung in Chinese and Chosun's philosophy. 2. Method of study First, I made a thorough investigation into the meaning and change of Sung-Jung's concept in Chinese philosophy. Secondly, I did a study not only Sadanchiljung(四端七情) that the discussion is based on the concept of Sung-Jung in Chosun's philosophy but also it of Jeong Je-du (a scholar of the Wang Yang-ming school). Finally, I did a study Sung-Jung in 3. Result of study It is found that Lee je-ma formulated his peculiar system of thought (Sa-Sim-Sin-Mul) in, , coverd the concept of Sung-Jung in Chinese and Chosun's philosophy.

Getah virus is known as a causative agent of recognized febrile illness of horses characterized by fever, rash and edema. A serological survey indicated that hemagglutination inhibition antibody against Getah virus was detected in 34% of 464 racehorses from Korean Horse Affairs Association and 57% of 262 ponies from Cheju island, respectively. Several field strains of Getah virus isolated were from the racehorse that have been shown fever and febrile signs in 1989. The field isolates produced cytopathic effect in Vero, MA-104, BHK-21 cell cultures. Especially, they multiplied to the highest titer($10^6TCID_{50}/0.1ml$) in Vero cell cultures. When day-old mice were inoculated with field isolates by the intracerebral route, they showed a typical paralysis sign and died within seven days after inoculation. The guinea pig exhibited skin rash and edema, and died with neural signs after inoculation with the field isolates. In the cross neutralization test and indirect immunofuorescent assay, the field isolates were proved to be closely related to the Sakai strain of Getah virus antigenically.

Sinomenium acutum has been used for the treatment of rheumatoid arthritis, arrhythmia, and pain. We evaluated the quality of S. acutum extract by quantitatively analyzing its components such as sinomenine, magnoflorine and syringaresinol with the simultaneous determination method using HPLC-DAD. A total of 53 samples collected from different localities were evaluated with this quality evaluation method. Sinomenine, magnoflorine and syringaresinol from tested samples ranged from 0.0649~9.1050%, 0.7460~10.7590% and 0.0010~0.2441%, respectively. In the current study, we were able to exhibit the diverse quality of S. acutum samples collected from various locations using the simultaneous determination method.

1. Backgrounds: There are a lack of comprehensive study on Taeeumin Exterior Heat syndrome diarrhea(表熱證泄瀉). Thus, The author examines the content of various literatures related to Tae-eumin Exterior Heat syndrome diarrhea. 2. Methods: Literature examination is used Lee, Je-ma's writings and Sasang Constitutional Medical doctor's writings. Syndrome examination is used Tae-eumin's study on Syndrome of DonguisusebowonGaboGu-bon("咸山沙村東醫壽世保元甲午舊本") and Donguisusebowon("東醫壽世保元") and treatises of the academic world. 3. Results: and Conclusions: 1) "Profuse sweating and reddish and difficult urination"(汗多而小便赤澁) is regard as Taeeumin Interior Febrile Disease(裏熱病). 2) There is no possibility of a misprint about Taeeumin Exterior Heat syndrome diarrhea. Taeeumin Exterior Heat syndrome diarrhea is engaged in both the Exterior and Interior(表裏俱病). 3) It is difficult to prescribe GalgeunHaegi-Tang(葛根解肌湯) instead of Galgeunnabokja-Tang(葛根蘿葍子湯). 4) Tae-eumin Exterior Heat syndrome diarrhea is formed in the early period and absorbed into Donguisusebowon ("東醫壽世保元") in the latter period. "Profuse sweating and reddish and difficult urination" is estimated to be added in the latter period.

Hall-type current sensors have been widely used in many fields such as elevator and train system. To estimate lifetime of hall-type current sensors, an accelerated life test with real-time monitoring system simultaneously was designed and performed in high temperature environment with three different temperatures. From the experimental results, activation energy was about 0.9 eV, and acceleration factor was about 450 based on Arrhenius model. As a results, $B_{10}$ lifetime of hall-type current sensor is estimated to be 65,460 hours.
