Various aspect of epidemics broke out continually from the middle of Joseon Dynasty due to the famine and drought caused by abnormal climate of the sixteenth century and the war. Thus the Dynasty performed sacrificial rites, isolated the patients and published plenty of medical books related epidemics in order to cure of the patients, and Heojun edited 『Byeokyeoksinbang』 as 'Dangdokyeok' broke out at Gwanbuk(關北) districts in 1613, Heojun explained the cause of Dangdokyeok as meteorology under the feudal conditions, and concluded Simhwa(心火) by fever toxin, Therefore he selected the method of puting out Simhwa by attack of fever toxin. In addition he presented emergency treatment that can maintain the airway by bleeding. To treat Dangdokyeok, Heojun presented lots of prescriptions so as Seungmagalgeuntang(升麻葛根湯), Cheongyeolhaedoksan(淸熱解毒散), Yeongyopaedok-san(連翹敗毒散), Bangpungtongsaongsan(防風通聖散), Jowiseunggitang(調胃升氣湯) and Hwangryeonhaedoktang(黃連解毒湯) etc. And he proposed Samdueum (三豆飮), Realgar(石雄黃) and so on to prevent infection from that. They presume from 120 to 150 years as the period of human adaptation to the first epidemics. Dangdokyeok put a large number of people to death at first, but it wasn't referred at the history any more after Byeokyeoksinbang. So we can say that the treatment of Heojun may be effective. Common cold and dyspeptic cold broke out in our country differently from 'Shanghan(傷寒)' in the China, so we had settled 'pestilence infectious epidemic disease(瘟疫)' while 'epidemic febrile disease(溫病)' of the China. Dangdokyeok of Heojun is similar to 'Scalet fever' belonging to 'virulent heat pathogen(溫毒)', 'newly epidemic febrile disease(新感溫病)'. As a cure of Dangdokyeok, the Korean medicine uses the treatment of removing fever state whereas the western medicine uses the antibiotics to kill the streptococcus. The symptoms of Dangdokyeok are remarkably similar to those of the Scarlatina, so this occupies a high position on the world history of medicine in aspects of the period and details of symptoms. These days we have the problems that the tolerance of antibiotics increases and disease of unknown cause is prevalent. It means the western medicine get to limits. So if we progress epidemiography based on Heojun's medicine, we may contribute to the world history of medicine.

Ultra-high performance liquid chromatography (UHPLC) systems are integral to modern analytical laboratories, necessitating careful maintenance and operation protocols to ensure optimal performance. This document provides comprehensive guidelines for the proper shutdown and reactivation of UHPLC systems to prevent damage and maintain operational efficiency. • Shutdown: Remove the column and replace it with a union to avoid blockages. Flush the system with a compatible solvent mix, clean mobile phase reservoirs to prevent microbial growth, flush the pump with storage solvent, and clean the autosampler, including the needle and injection port. • Reactivation: Inspect the system for wear or damage, gradually reintroduce mobile phases starting with a weak solvent, reinstall the column securely, and perform system checks on baseline stability, pressure consistency, and detector performance. By adhering to these guidelines, laboratories can ensure the longevity and reliability of their UHPLC systems, maintaining high analytical performance and minimizing downtime. These procedures help prevent common issues such as blockages, contamination, and component wear, thereby supporting efficient and accurate analytical operations.

Purpose: Chest radiography is often performed on patients hospitalized with typical clinical manifestations of bronchiolitis. We aimed to determine the proportion of subjects with pathologic chest radiographic findings and the clinical predictors associated with pathologic chest radiographic findings in young children admitted with the typical presentation of bronchiolitis. Methods: We obtained the following data at admission: sex, age, neonatal history, past history of hospitalization for respiratory illnesses, heart rate, respiratory rate, the presence of fever, total duration of fever, oxygen saturation, laboratory parameters (i.e., complete blood cell count, high-sensitivity C-reactive protein [hs-CRP], etc.), and chest radiography. Results: The study comprised 279 young children. Of these, 26 had a chest radiograph revealing opacity (n=24) or atelectasis (n=2). Multivariate logistic regression analysis showed that after adjustment for confounding factors, the clinical predictors associated with pathologic chest radiographic findings in young children admitted with bronchiolitis were elevated hs-CRP level (>0.3 mg/dL) and past history of hospitalization for respiratory illnesses (all P<0.05). Conclusion: The current study suggests that chest radiographs in young children with typical clinical manifestations of bronchiolitis have limited value. Nonetheless, young children with clinical factors such as high hs-CRP levels at admission or past history of hospitalization for respiratory illnesses may be more likely to have pathologic chest radiographic findings.

1. Objective This study aimed to find out the epidemiologic characteristics of constitutional disease syndromes at a hospital of Oriental medicine in Seoul. 2. Methods The medical records of 1354 subjects who have received prescriptions and diagnosis of Sasang constitution from January 2008 to December 2009 at a hospital of Oriental medicine were reviewed. General factors and the frequency of the prescriptions according to Sasang constitution were compared and analyzed. 3. Results 1) Among the 1354 subjects, 562(41.5%) persons were males and 792(58.5%) females. 614(45.3%) persons were Soeumin, 369(27.3%) Soyangin, 364(26.9%) Taeumin, and 7(0.5%) Taeyangin. 2) The frequencies of the prescriptions of 14 constitutional disease syndromes were compared. Taeum Syndrome, Esophagus Cold Syndrome and Yin Deficiency Tidal fever Syndrome show the high frequencies among 14 disease syndromes. Chest Heat Syndrome, Deficiency of Yin and Blood syndrome and Soeum Syndrome show the low frequencies among 14 disease syndromes. Interior disease(63.4%) was higher than exterior disease(36.6%) and mild disease(61.8%) was higher than severe disease(38.2%). 3) Among all constitutional prescriptions, Jowyiseungchung-tang was the most common and next rankings were Gupoong-tang and Dokhwaljihwang-tang in turns. 4. Conclusions From all these considerations, it would seem that Taeum Syndrome in Soeumin, Esophagus Cold Syndrome in Taeumin and Yin Deficiency Tidal fever Syndrome in Soyangin show the high frequencies in a hospital of Oriental medicine in Seoul. Large-scale epidemiologic study in Sasang constitutional medicine may be needed on various ways and places.

The structural proteins of classical swine fever virus (CSFV) consist of nucleocapsid protein C and envelope glycoprotein $E^{rns}$ (E0), E1 and E2. Among them, E2, the most immunogenic of the CSFV glycoproteins, induces a protective immune response in swine. In this study, to determine the optimal expression conditions of glycoprotein E2 using baculovirus system, we investigated the influence of insect cells and media to the expression of recombinant E2. Recombinant virus containing glycoprotein E2 coding gene was constructed with bApGOZA DNA. Expression of the glycoprotein E2 was analyzed by SDS-PAGE and Western blot analysis using anti-CSFV E2 monoclonal antibodies. Expression of glycoprotein E2 in Sf21 cells was first observed after 3 days and reached a maximum on the 5th day after infection. Furthermore, the highest levels of glycoprotein E2 expression were observed at multiplicity of infection (MOI) of 5. When three different insect cell lines (Sf21, High-Five and Se301) were tested, High-Five cells showed the highest production. In addition, four different serum-free and serum-supplemented media, respectively, were tested for the expression of glycoprotein E2 and the budded virus (BV) titers. As a result, serum-supplemented medium provided the best conditions for protein production and the BV yield.
