A total of 1,498 small mammals (rodents and insectivores), including Apodemus agrarius (n= 1,366), Crocidura lasiura (54), Mus musculus (32), Micronytus fortis (28), Eothenomys regulus (9), Micronys minutes (6), and Cricetulus triton (3), were live-trapped in Gyeonggi-do (Province) (Paju-si, Pocheon-gun, and Yeoncheon-gun) near the demilitarized zone (DMZ) from December 2004 to September 2005. A. agrarius was found to be infected with 3 species of echinostomes (Echinostoma hortense, Echinostoma cinetorchis, and Euparyphium murinum), while C. lasiura was infected with 1 species (Echinochasmus japonicas) of echinostome. Other mammals were free from echinostome infections. Total 16 E. hortense were detected in 7 (0.5%) mice, 9 E. cinetorchis from 5 (0.4%), and 3 E. murinum from 2 (0.1%) out of 1.366 A. agrarius examined. E. japonicus was found only in 1 (1.9%; total 3 specimens) C. lasiura. These results demonstrate that A. agrarius and C. lasiura, inhabiting near the DMZ of Gyeonggi-do serve as the natural definitive hosts for several species of echinostomes, although their infection rates are low. This is the first record of natural infections of A. agrarius with E. cinetorchis and C. lasiura with E. japonicus in the Republic of Korea.

A new endemic focus of Gymnophalloides seoi infection has been discovered on Aphae Island(Shinan-gun, Jeollanam-do), Republic of Korea. This area, which is referred to as Bokyong-ri, is a small seashore village located in the northern portion of the island. Fecal samples were collected from a total of 57 residents and examined by the Kato-Katz and formalin-ether sedimentation techniques. Helminth eggs were detected in 37 samples(64.9%); 33 samples were positive for G. seoi eggs(57.9%), 4 for Pygidiopsis summa(7.0%), 13 for other heterophyids(22.8%), 1 for Clonorchis sinensis(1.7%), and 1 for Trichuris trichiura(1.7%). Women(70.4%) revealed higher rates of G. seoi infection than did men(46.7%), and individuals older than 50 years of age also evidenced higher rates of G. seoi infection than in other age groups(P<0.05). In worm collection from 13 G. seoi egg positive cases, G. seoi (total 86,558 specimens), Heterophyes nocens(278), Stictodora sp.(10), Heterophyopsis continua(3), P. summa(3), and unidentified flukes(42) were collected. Oysters, the source of G. seoi infection, were collected from an area proximal to the village and 50 were examined for metacercariae; 47(94%) were found infected and the observed metacercarial density was $9.5{\pm}8.9$ per oyster. The results of this study indicate that Bokyong-ri is a new endemic area of G. seoi infection, with high rates of infection in humans and oysters.

Relatively little has been studied on the AMA-1 vaccine against Plasmodium vivax and on the plasmid DNA vaccine encoding P. vivax AMA-1 (PvAMA-1). In the present study, a plasmid DNA vaccine encoding AMA-1 of the reemerging Korean P. vivax has been constructed and a preliminary study was done on its cellular immunogenicity to recipient BALB/c mice. The PvAMA-1 gene was cloned and expressed in the plasmid vector UBpcAMA-1, and a protein band of approximately 56.8 kDa was obtained from the transfected COS7 cells. BALB/c mice were immunized intramuscularly or using a gene gun 4 times with the vaccine, and the proportions of splenic T-cell subsets were examined by fluorocytometry at week 2 after the last injection. The spleen cells from intramuscularly injected mice revealed no significant changes in the proportions of CD8$^+$ T-cells and CD4$^+$ T-cells. However, in mice immunized using a gene gun, significantly higher (P<0.05) proportions of CD8$^+$ cells were observed compared to UB vector-injected control mice. The results indicated that cellular immunogenicity of the plasmid DNA vaccine encoding AMA-1 of the reemerging Korean P. vivax was weak when it was injected intramuscularly; however, a promising effect was observed using the gene gun injection technique.

The purpose of this study is to survey on the pharmacists' medication teaching service for topical steroids in regions without separation of dispensary from medical practice. The questionnaire was sent to 199 pharmacists who work inregions without separation of dispensary from medical practice via mail, e-mail or fax. 112 out of 199 pharmacists requested have answered the survey (response rate 56.28%). The questionnaire was composed of 4 categories with demographic characteristics, generally explained contents, adverse effects and precaution in pregnancy, breastfeeding and children. We analyzed the questionnaire by the 6 items with reference to the practical guidelines for medication teaching service. The medication teaching service for topical steroids in terms of generic name, physical characteristics, efficacy, usage and dosage, warning and precaution has been well provided by pharmacists in regions without separation of dispensary except for means and duration of optimal storage. The majority of pharmacists provided their patients with 4 and more kinds of items (69.64%), but the generally recommended 4 kinds of items such as generic name, efficacy, usage and dosage, warning and precaution were provided in as low as 48.22% of the respondents. These results show that the medication teaching service for topical steroids in terms of means and duration of optimal storage (45.54%) and the generally recommended 4 kinds of items have not been enough provided by pharmacists in regions without separation of dispensary. Taken together pharmacists in these regions should make a proper guideline for medication teaching service that can prevent the adverse effects of topical steroids.

There experiment were carried out to analyze for pesticide residues in 4 kinds of dried fruits collected in northern area of Seoul in 2007~2009. Total of 213 samples were analyzed. According to the results, 20 kinds of residual pesticides were detected. Residual pesticides were detected in 66 samples (31.0%) and 8 samples (3.8%) exceeded maximum residue limits (MRL). Cypermethrin, fenvalerate, endosulfan, chlorpyrifos, bifenthrin were detected frequently. The Pesticide types which were detected in dried furits were revealed in order of pyrethroid > organophosphate > organochloride > dicarboximide. Detection rates of dried fruits were dried chinese matrimony vein (53.0%), dried jujube (34.9%), dried rubi fructus (7.6%) and dried maximowiczia chinensis (4.6%). Based on these results, we investigated the risk assessment from amount of residual pesticide in dried jujube. Range of %ADI were 0.0001~0.0081%, but the value has not effected on human health.

SNe light curves have been used to understand the expansion history of the universe, and a lot of efforts have gone into understanding the overall shape of the radioactively powered light curve. However, we still have little direct observational evidence for the theorized SN progenitor systems. Recent studies suggest that the light curve of a supernova shortly after its explosion (< 1 day) contains valuable information about its progenitor system and can be used to set a limit on the progenitor size, R*. In order to catch the early light curve of SNe explosion and understand SNe progenitors, we are performing a ~8hr interval monitoring survey of nearby galaxies (d < 50 Mpc) with 1-m class telescopes around the world. Through this survey, we expect to catch the very early precursor emission as faint as R=21 mag (~0.1 Rsun for the progenitor). In this poster, we outline this project, and provide updates on IMSNG projects during 2017/2018 seasons.

To ascertain residual sonographic and histopathological findings of clonorchiasis after treatment, the present study evaluated sonographic findings in rabbits which were infected with 500 metacercariae of C.sinensis every 6 months for 18 months after treatment with praziquantel. The sonographic findings were analyzed in terms of intrahepatic bile duct dilatation and periductal echogenicity, and histopathological findings were observed after the last sonographic examination. Compared with the sonographic findings before treatment, dilatation of the intrahepatic bile ducts became mild to some degree in four of the seven cases and increased periductal echogenicity resolved in four of them. The histopathological specimens after 18 months showed that periductal inflammation has almost resolved but moderate dilatation of the intrahepatic ducts and mucosal hyperplasia persisted. The periductal fibrosis minimally resolved. The log-lasting sonographic findings in cured clonorchiasis make sonography less specific.

Background : The fact that only 10-20% of chronic cigarette smokers develop chronic obstructive pulmonary disease (COPD) reflects the presence of genetic factors associated with the susceptibility to COPD. Recently, it was reported that the surfactant protein A increases the secretion of matrix metalloprotease 9, which degrades extracellular matrices of the lung, through a Toll-like receptor 2 (TLR2). In this context, possible role of TLR2 in the pathogenesis of COPD was postulated, and a functional dinucleotide repeat polymorphism in intron II of TLR2 was evaluated for any association with COPD. Method : Male patients with COPD and male smokers with a normal pulmonary function were enrolled in this study. The number of Guanine-Thymine repeats in intron II of the TLR2 gene were counted. Because the distributions of the repeats were trimodal, the alleles were classified into three subclasses, 12-16 repeats: short (S) alleles; 17-22 repeats: medium length (M) alleles; and 23-27 repeats: long (L) alleles. Result : 125 male patients with COPD and 144 age- and gender-matched blood donors with a normal lung function were enrolled. There were no differences in the distribution of each allele subclass (S, M and L) between the COPD and control group (p=0.75). The frequencies of the genotypes with and without each allele subclass in the COPD and control group were similar. Conclusion : A microsatellite polymorphism in intron II of TLR2 gene was not associated with the development of COPD in Koreans.

Acromegalic patients can develop mild upper airway obstruction. However, the limitation of both vocal folds mobility developing dyspnea is rare. We report a case with bilateral vocal cord paralysis associated with acromegaly. The patient visited our clinic presenting dyspnea showing bilateral vocal cord hypomobility in laryngoscopy. The patient underwent a tracheostomy and a transsphenoidal resection of the pituitary adenoma. Thereafter, laser cordotomy with medial arytenoidectomy was done for the permanent treatment of glottal obstruction. The tracheotomy canula was successfully removed one month after the surgery.

26세 여자환자가 우측 흉통을 주소로 응급실을 방문하였다. 흉부방사선검사에서 우측 기흉을 진단받고 흉관삽입술을 시행하였다. 환자는 6년전부터 레이노드 현상이 있었고 양손에 피부경화증이 있었으며 항 DNA 국소이성화효소 I 항체가 양성으로서 전신성 경화증을 진단받았다. 고해상력 컴퓨터단층촬영에서 양쪽 폐야에 낭종성 병변이 관찰되었고 기흉은 낭종의 파열에 의한 것으로 판단되었다. 전신성 경화증은 폐를 포함한 여러 장기를 침범하는 질환이다. 이 질환에서 기흉과 낭종성 폐병변이 발생하였던 증례들은 1954년 이래로 보고되어 왔는데 모든 증례에서 기흉은 전신성 경화증을 진단받은 뒤에야 발견된 것이었다. 본 증례는 기흉으로 발현한 전신성 경화증의 첫 증례라는 점에서 임상적 의의가 있다고 여겨진다.
