Human sparganosois was reported more than 100 cases in Korean population. However no case reported yet in Korea as a patient was infected by sparganum from other geographical area, such as Thailand. The case we are reported here is a 38 year-old Korean male who had been suffered from mass being a small, round and soft consistance in upper portion of his right thigh. The patients stated that he had an opportunity to eat living snake in Bangkok, Thailand during trip. As therapy praziquantel (75㎎/㎏/day) was given p.o. for 14 days, but in vain to cure. Following medical treatment, surgical exicision was performed to remove a alive, soft, whitish-milky, mobile and elongated sparganum. Serlogical test by micro-ELISA for sparganum-specific antibody revealed a high serum antibody level of absorbance 0.67 (positive criterion: absorbance 0.22).

Background: A hyperosmolar nonketotic state has been known to have a high mortality, and even now, despite this high mortality, only a few studies of this disease have been performed. We studied the prognostic factors for the hyperosmolar nonketotic state. Methods: We retrospectively studied the cases of 40 patients who were in a hypersomolar nonketotic state when admitted to Sanggye Paik Hospital during the 6-year Period from 1995 through 2000. We divided the hyperosmolar nonketotic patients into two groups, the complete recovery group and the incomplete recovery group, and compared the clinical features, the laboratory findings, and the precipitating factors between two groups. Results: 1) A total of 40 patients were studied: 24 in the complete recovery group and 16 patients in the incomplete recovery group. The mortality rate was 32.5%. 2) No significant statistical difference existed among the clinical features of the two groups, except for the sex(p<0.01). 3) Among the laboratory findings of both groups, analysis revealed that the effective osmolarity was significantly higher among those in the incomplete recovery group(p<0.01). Serum sodium concentration was also significantly higher among those in the incomplete recovery group(p<0.01). Serum creatinine was also significantly higher among those in the incomplete recovery group(p<0.05). Serum bicarbonate concentration, on the other hand, was significantly lower among those in that group(p<0.05).4) Infection was identified as the most common precipitating factor(62.5%). Among the precipitating factors of the two groups, there were significant statistical difference in pneumonia, UTI, and inappropriate glucose control. 5) A significant statistical difference existed among the initial level of consciousness of both groups(p<0.05). 6) The only significant independent factor responsible for prognosis of nonketotic hyperosmolar state patients was the sex. Conclusion: The sex was only significant independent prognostic factor of nonketotic hyperosmolar state patients.

Effect of Serum IGF-I on Progesterone Concentration during Early Pregnancy in Korean Native Cattle (Hanwoo)

Ryu, Yang-Hwan,Yang, Jong-Yong,Seo, Dong-Sam,Ko, Yong Asian Australasian Association of Animal Productio 2003 Animal Bioscience Vol.16 No.2

Insulin-like growth factor-I (IGF-I) is a polypeptide that has the function of regulating the expression of steroid hormones through endocrine, paracrine, and autocrine actions in reproductive organs. Moreover, IGF-I is involved in ovulation, implantation, maintenance of pregnancy, and development of fetuses in animals. Therefore, this study was conducted to investigate the effects of serum IGF-I concentration on progesterone ($P_4$) concentration and pregnancy rates in Korean native cattle (Hanwoo). Blood was collected at estrus (Day 0) and Day 11. Artificial insemination was performed at Day 0. Serum IGF-I and $P_4$ concentrations were measured by radioimmunoassay (RIA). Overall, $P_4$ concentration was higher at Day 11 than Day 0, whereas the pattern of IGF-I concentration was reversed. When animals were divided into two groups depending on the pregnancy status, $P_4$ concentrations of the pregnant group was significantly higher than that of the non-pregnant group at Day 0 (p<0.05) and Day 11 (p<0.05). But, lower IGF-I concentrations were detected in the pregnant group at Day 0 (p<0.05) and Day 11 (p<0.05) compared to the non-pregnant group. In conclusion, these results indicated that serum IGF-I is inversely associated with $P_4$ concentration during early pregnancy in Hanwoo.

A Study on the Characteristics of the Heavy Rainfall Events in Honam District along the Border of mT Airmass

Se-Hwan Yang, Chan-Su Ryu 조선대학교 기초과학연구원 2012 조선자연과학논문집 Vol.5 No.4

District of Korea affected by westerly wind and heavy rainfall is predominantly distributed in the west and south of Honam district. So, this study is becoming a necessity. In this study, it is investigated that the characteristics of heavy rainfall occurred frequently in Honam district along the border of mT airmass after the end of rainy season due to atmospheric instability, lower (850 hPa) convergence and topographic effect. Our results show that heavy rainfall occurred in Honam district along the border of mT airmass results from the appropriate mechanism of the unstable vertical structure and moisture flux in the expansion and contraction of the border of mT airmass. All things considered, the improvement of the predictability of heavy rainfall occurred in Honam district along the border of mT airmass could be possible by the generalization of the results of this study.

Park Do-Yang,Lee Yong Ju,Kim Dong-Kyu,Kim Soo Whan,Yang Hyeon-Jong,Kim Do Hyun,Jun Young Joon,Park Sang Chul,Kim Bong-Seong,Yang Song-I,Lee Il Hwan,Kim Minji,Ryu Gwanghui,강성윤,Kim Mi-Ae,이상민,Kim Hyun-Ju 대한천식알레르기학회 2023 Allergy, Asthma & Immunology Research Vol.15 No.2

Allergic rhinitis is the most common chronic disease worldwide. Various upper airway symptoms lower quality of life, and due to the recurrent symptoms, multiple treatments are usually attempted rather than one definitive treatment. There are alternatives to medical (medication-based) and non-medical treatments. A guideline is needed to understand allergic rhinitis and develop an appropriate treatment plan. We have developed guidelines for medical treatment based on previous reports. The current guidelines herein are associated with the “KAAACI Evidence-Based Guidelines for Allergic Rhinitis in Korea, Part 1: Update in pharmacotherapy” in which we aimed to provide evidence-based recommendations for the medical treatment of allergic rhinitis. Part 2 focuses on non-pharmacological management, including allergen-specific immunotherapy, subcutaneous or sublingual immunotherapy, nasal saline irrigation, environmental management strategies, companion animal management, and nasal turbinate surgery. The evidence to support the treatment efficacy, safety, and selection has been systematically reviewed. However, larger controlled studies are needed to elevate the level of evidence to select rational non-medical therapeutic options for patients with allergic rhinitis.

Objective : The aim of this study were to investigate degree of satisfaction in referring physicians' psychiatric consultation services and their altitudes and opinions toward psychiatry, and the correlation between two them. Method : A total of 159 survey questionnaire were distributed to physicians in a University Hospital. The questionnaires contained the level of satisfaction in referring physicians' psychiatric consultation services and their attitudes and opinions toward psychiatry. 135 surveys were returned, representing 85% return rate. Statistical method used were Cronbach's alpha coefficient for testing reliability, factor analysis for testing validity, and t-test or ANOVA with SAS. Results : Internal consistency reliability was tested by Cronbach's alpha. Cronbach's α was 0.8594 for total 23 items. Twenty-three items and seven factors were emerged and these contributed 66.8% of the variance in the total score. Factor Ⅰ in the psychiatric consultation questionnaire was positively correlated with overall merits of the field of psychiatry in the attitude questionnaire, factor Ⅱ in the psychiatric consultation questionnaire was positively correlated with possible abuses and social criticisms in the attitude questionnaire, factor Ⅲ in the psychiatric consultation questionnaire was positively correlated with efficacy in the attitude questionnaire, factor Ⅴ in the psychiatric consultation questionnaire was positively correlated with possible abuses and social criticisms in the attitude questionnaire, factor Ⅵ in the psychiatric consultation questionnaire was positively correlated with overall merits of the field of psychiatry in the attitude questionnaire. Conclusions : Our results supported the hypothesis that referring physicians' satisfaction to the psychiatric consultation was positively correlated with psychiatrists' attitude, and that physicians with more positive attitudes and those had more knowledge on psychiatry showed greater satisfaction in psychiatric consultation service than those without.
