The patients with prolonged air leak after lung resection surgery were generally treated by pleurodesis with sclerosing agents such as talc, tetracyclin, doxycyclin, bleomycin, vibramycin, and OK432. However, for the case like dead space resulted by incomplete reexpansion of the remaining lung, chemical pleurodesis has shown to be not as effective as expected. If the patients keep the chest tube for long period of time, the risk of thoracic empyema would increase. Most thoracic surgeons have experienced prolonged airleak which developed after lung resection. Pleurodesis with autoblood was reported as an effective method in treatment of patients with prolonged airleak. The mechanism of blood pleurodesis may be direct obliteration of BPF and reduction of dead space by clot. Therefore we successfully treated the two patients with prolonged airleak using the autoblood plus OK432 or vibramycin.

This study was carried out to find out PSS(Porcine Stress Syndrome) with the PSE(Pale, Soft, Exudative) in different piglets. These experiments were accomplished with the aid of PCR-RFLP(Polymerase Chain Reaction-Restriction Fragment Length Polymorphism). The samples were collected and examined from umbilical cord blood of piglets of Yorkshire, Landrace and Crossbred. And then, the PCR products were digested by restriction enzyme, Hha I. The results obtained were as follows; The PCR products of the blood genomic DNA of ryanodine receptor gene were length of 1 .8kb in umbilical cord blood. Normal type(NN), heterozygous type(Nn) and recessively homozygous type(nn, PSS) as a result of digestion of restriction enzyme, Hha 1, were 90.0%, 10.0% and 0.0% in Yorkshire piglets, 76.2%, 19.0% and 4.8% in Landrace, 69.1%, 23.8% and 7.1% in crossbred, respectively. As already showing the above results, the blood from piglets umbilical cord can be availably used for the determination of genotypes of PSS because of easiness of blood collection without stress in live piglets.

Purpose: This study was designed to investigate the changes of vision and ocular functions induced by increase of blood alcohol level. Methods: Blood alcohol level, vision, refractive errors, near point convergence, heterophoria, and relative convergence were measured at 1 h, 4 h, and 24 h after acute alcohol ingestion of 0.7 g per kg body weight. Results: At 1 h after alcohol ingestion, myopization and ocular functions which measured near point convergence, positive and negative convergences, and degree of heterophoria remarkedly worked a changes accompanied with the maximum value of blood alcohol level. But at 24 h after that, all of ocular functions were recovered to degree of 90~99% compared with non-alcoholic normal conditions. Conclusions: As the increase of blood alcohol level is able to induce the significant changes of visual acuity and ocular functions, opticians have to understand thoroughly the patient's conditions by alcohol ingestion before refractive test and ocular examinations.

Objects: This study is a descriptive study to identify the factors influencing the glycated hemoglobin control in type 2 diabetes patients. Methods: This study used raw data from the third year of the National Health and Nutrition Examination Survey performed from 2015. The subjects were 285 people who were classified as type 2 diabetes patients among the 7,380 participants of the National Health and Nutrition Examination Survey. Findings: The factors influencing the glycated hemoglobin control in type 2 diabetes patients were found to be age, education level, prevalence period and sleeping time. Improvements: In type 2 diabetes patients, it is very important to have appropriate education on diabetes when they discovered the disease morbidity in the middle age rather than in the aged period and to have enough sleeping time. A practical program to help this education and training should be developed.

We have investigated the expression of early growth response protein 1 (EGR1) in INS-1 pancreatic β-cells treated with Allomyrina dichotoma hemolymph. The Korean rhinoceros beetle, A. dichotoma (Coleoptera: Scarabaeidae), is important in the insect industry for medical applications. We have already established a method for purification of A. dichotoma hemolymph that can be used in many experiments. EGR1 is reported as a multifunctional transcription factor that is implicated in virus infections. EGR1 has therefore been revealed as a major mediator and regulator in the physiological and pathological conditions of several cell and tissue types. New findings in this study are that A. dichotoma hemolymph, which promotes a dose- and time-dependent upregulation of EGR1 gene expression, shows an enhancement of this gene expression when combined with hypothermia or endoplasmic reticulum (ER) stress. These results suggest that A. dichotoma hemolymph may provide clues to EGR1-associated disease therapies involving gene regulation of EGR1.

Background: Cytokine-mediated ex vivo expansion has been proposed as a means of increasing the number of cord blood (CB) hematopoietic stem cells for transplantation. As well as stem cell number, stromal cells are necessary for functional maturation of hematopoiesis. The purpose of this study was to analyze the development of stromal cells during ex vivo expansion of CB $CD34^+$ cells. Methods : $CD34^+$ cells were purified from CB by magnetic bead selection. The levels of of interleukin-3, interleukin-$1{\beta}$, interleukin-6, granulocyte macrophagecolony stimulating factor and tumor necrosis factor-${\alpha}$ were measured in culture supernatants on 0, 1, 2, and 3 weeks, using ELISA techniques. CB $CD34^+$ cells were expanded in Iscoves modified Dulbeccos medium in the presence of several cytokines. The expression of E-selectin, vascular cell adhesion molecule-1, intercellular adhesion molecule-1, platelet/endothelial cell adhesion molecule-1, von Willebrand factor, vimentin, and CD14 in newly developed stromal cells was examined by immunocytochemical method. Relevant extracellular matrix (ECM) proteins and proper cytokines were also assayed for the most suitable condition for expansion of stromal cells. Results: Several cytokines were found to have been produced by CB $CD34^+$ cells as well as bone marrow-derived $CD34^+$ cells. During ex vivo expansion of CB $CD34^+$ cells, stromal cells appeared in the culture by day 4 and expanded over the following 7-10 days before being confluent by day 2 1. These cells expressed surface markers characteristic of cells of endothelial lineage. Furthermore, these stroaml cells also expanded effectively when treated with thrombopoietin+flt-3 ligand+stem cell factor+leukemia inhibitory factor or 0.1% poly-L-lysine-coated wells. Conclusion: Stromal cells were developed during ex vivo expansion of CB $CD34^+$ cells and that this development could be enhanced further by treating the stromal cells with cytokines or ECM.

Purpose : Ghrelin stimulates the secretion of growth hormone and other pituitary hormones, and has orexigenic effects. It may have a physiologic role in fetal and neonatal growth. Leptin secreted by the adipocytes reflects fat mass in infants as well as adults. The aim of this study was to evaluate the relation of cord blood ghrelin and leptin levels to body weight(BW), body mass index(BMI), insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding protein-3(IGFBP-3) levels in appropriate for gestational age(AGA) newborns. Methods : Sixty healthy AGA newborns(31 males and 29 females, gestational age[GA] 34-42 weeks) were included in this study, whose BW and BMI were measured at delivery. Umbilical cord venous blood samples were withdrawn, and ghrelin and leptin were measured by radioimmunoassay. Cord blood IGF-I and IGFBP-3 were determined by immunoradiometric assay. Results : The mean levels of ghrelin were inversely correlated with BW(r=-0.29, P<0.05) and GA (r=-0.28, P<0.05), but were not affected by gender. The mean levels of leptin levels showed positive correlation with BW(r=0.44, P<0.01), GA(r=0.36, P<0.01), and BMI(r=0.28, P<0.05). The leptin levels of females were higher than those of males. There was no gender difference in leptin levels in neonates under GA 37 weeks. However, the leptin levels of females were higher than those of males (P<0.01) in newborns with GA 37 weeks or over. There was no correlation between ghrelin and leptin levels. Ghrelin and leptin levels showed no relations to cord blood IGF-I and IGFBP-3 levels. Conclusion : These data suggest that cord blood ghrelin may have an inverse correlation with BW in AGA newborns, and leptin levels are positively correlated with BW and fat mass. Further study of ghrelin concentrations in cord blood is necessary to elucidate the physiological and pathological roles of ghrelin during the fetal and neonatal periods.

OQ-21을 암·수 ICR계 마우스에 복강투여 하여 급성독성을 측정한 결과 최대용량 투여군에서도 사망한 동물은 관찰되지 않았다. 그리고 시험동물을 부검하여 육안 관찰한 결과 OQ-21 투여군은 대조군과 전혀 차이가 없었고 실제 독성도 비교적 낮은 것으로 판단된다. 또한 OQ-21이 혈과에 수축 반응에 영향을 미치는 지를 연구한 결과 용량 의존적으로 phenylephirne에 의한 혈관 수축을 증가시킴을 관찰하였다. 이상의 결과로부터 OQ-21은 급성독성이 약한 것으로 생각되지만 혈관 수축에 미치는 영향은 앞으로 인체 안전성에 관하여 검토하여야 할 과제로 사료된다.
