Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

Streptozotocin-당뇨병 백서에서 당뇨병 이환기간에 따른 대동맥의 이완능 저하 및 Oxygen-Free Radical에 의한 이완능의 손상정도

김정국,김신우,김수동,서예경,하승우,김보완,백운이,권삼,강승완 경북대학교 병원 1997 경북대학교병원의학연구소논문집 Vol.1 No.1

목적: 당뇨병의 이환기간이 혈관의 내피세포 의존성 및 비의존성 이완능의 저하에 미치는 영향과 이환기간에 따라 oxygen-free radical(OFR)에 의한 동맥이완능의 손상정도에 차이가 있는지를 알아보고자 하였다. 방법: Streptozotocin(STZ)으로 당뇨병이 유도된 3 주 및 10주째의 백서군과 연령이 비슷한 정상 대조백서군의 적출 대동맥환을 norepinephrine으로 수축시킨 상태에서 내피세포 의존성 이완제인 acetylcholine(ACh) 및 비의존성 이완제인 nitroglycerine(NTG)에 대한 이완능을 즉정하여 비교 관찬하였다. 또한 xanthine과 xanthine oxidase의 혼합으로 생성된 H₂O₂에 대동맥환을 노출시킨뒤 역시 ACh과 NTG에 대한 이완능의 손상정도를 비교하였다. 결과: 3주및 10주째 당뇨병 백서의 대동맥환은 모두 대조군 백서의 대동맥환에 비해 ACh에 대한 이완능이 유의하게 감소하였으며 10주째 당뇨병 백서군에서의 ACh에대한 이완능의 저하는 3 주째 당뇨병 백서군에 비해 유의하게 심하였다.H₂O₂에 노출시킨 뒤 ACh에대한 이완능은 3주 및 10주 째 당뇨병 백서군에서 모두 대조군에 비해 유의하게 심한 손상을 보였으나 3주와 10주째 당뇨병 백서군 사이의 손상정도의 차이가 통계학적으로 유의하지는 않았다. 한편 3주 및 10주째 당뇨병 백서군 모두 NTH에 대한 대동맥환의 이완능은 대조 백서군과 별다른 차이가 없었으며 또 H₂O₂에 노출시킨 뒤에도 NTG에 대한 이완능의 손상은 관찰되지 않았다. 결론: STZ-당뇨병백서에서 대동맥의 이완능은 당뇨병에 이환된지 3 주째에 이미 ACh에 대한 내피세포 의존성 이완능이 선택적으로 저하되며 당뇨병의 이환기간이 길수록 이완능의 저하가 심하였고, OFR에 의한 동맥 이완능의 손상도 내피세포 의존성 이완능에만 선택적으로 나타나나 이환기간에 따라 OFR에 의한 이완능 손상정도에는 뚜렷한 차이가 없음을 시사하고 있다. Objectives: Diabetes mellitus produces histological evidence of endothelial as well as changes in vascular function in experimental animal. Oxygen free radicals interfere with of destroy endothelium-dependent relaxation in normal and diabetic blood vessels. The present study was investigated whether the duration of diabetic state can affect the severity of impairment in endothelium-dependent and/or independent relaxation and the sensitivity to oxygen free fadical (OFR)-induced damage in diabetic rat vasculature. Methods: The relaxative responses of aortic ring precontracted with norepinephrine in vitro to cumulative concentrations of acetylcholine (ACh) and nitroglycerine (NTG) were conducted in 3- and 10- week streptozotocin (STZ)-diabetic rats and agematched controls. After exposure to H₂O₂generated by mixing xanthine and xanthine oxidase, the degree of impairment in relaxative responses to ACh and NTG were also compared between 3- and 10-week diabetic rats. Results: The relaxative responses of aortic rings produced by cumulative concentrations of ACh were significantly lower in both 3- and 10-week diabetic rats than in the age-matched controls. The impairments of relaxative responses to ACh in 10-week diabetic rats were significantly greater than those in 3-week ones. After H₂O₂ exposure, the impairments of relaxative responses to ACh in 3- and 10-week diabetic aortas was also significantly greater than those in the control in the control ones. However, the severity of H₂O₂-induced damage in 10-week diabetic aortas was not significantly different than that in 3-week ones. In contrast, aortic rings of 3- and 10-week diabetic rats could still be fully relaxed by NTG, even after exposure to H₂O₂. Conclusion: These findings suggest that in SRZ-diabetic rat aortas selective impairment of endothelium-dependent relaxation to Ach can be found early even over a 3-week period after the induction of diabetes and the impairment may be greater in those with the longer duration of the diabetic state and that the impairment of the vascular relaxation by OFR is also selective to endothelium-dependent response but the sensitivity of OFR-induced damage may not be related to the duration of the diabetic state.

김운주,최은희,김기현,김정숙,송현숙,정은옥 충북대학교 교육 ·생활연구소 생활과학연구센터 2002 생활과학연구논총 Vol.6 No.1

The purpose of this study was to develop the instrument to assess the TV cooking program contents and to indentify the difference of cooking program contents according to professionalism of MC. The evaluation sheet was composed of 5 sectors(sanitary practices, cooking process, information & proceeding, table setting & tasting, applicability) with all 32 questions, 5-Likert scale was used. College students majoring in food & nutrition were very interested in cooking program and 72.4% of respondents knew the cable TV Food channel. The major source of cooking information was TV(51.5%). The comparison of four TV cooking programs with professional MC(2 program) and amateur MC(2 program) was performed. Except applicability sector, the mean evaluation scores of professional cooking program were higher than amateur cooking program. In the amateur MC program, 'hand washing', 'use of hair restraints', 'separate use of cutting board', 'dish towel cleanliness', 'separation of service table', 'taking a chair in tasting', 'use of individual dish' items rated low rating score(<2.00) so more control was needed. The findings of this research suggest that cooking professional should be participate in developing TV cooking program as MC or staff.

Craves병 환자에서 백혈구와 갑상선 조직의 HLA-DR β 유전자 부위의 비교

양인명,우정택,팽정령,서광식,김성운,김영설,김광원,최영길 경희대학교 유전공학연구소 1989 遺傳工學論文集 Vol.1 No.-

정상 갑상선세포에서는 HLA-DR 항원이 발현되지 않았으나, 그레이브스병 환자의 갑상선세포 표면에는 HLA-DR 항원이 발현됨이 보고되어, 이러한 현상은 이 질환의 자가면역 기전에 중요한 역할을 하고 있을 것으로 생각되고 있다. 한편 최근 DR이나 DQ 유전자의 상부 159kb 이내에는 이들의 발현을 조절하는 유전자가 존재함이 알려져 있고, 이 부위의 구조적인 변화로 인하여 DR DQ 유전자의 발현을 유도하는 여러 가지 핵내 인자들과 interferon-r 와 같은 외부인 자들이 보고되고 있다. 그러나 그레이브스병에서 이들 유전자 부위의 구조적인 변화에 관해서는 아직 보고가 없다. 이에 본 연구자 등은 이러한 가능성 여부를 규명하고자 2명의 전형적인 그레이브스병 환자의 수술 우 얻어낸 갑상선 조직에서 RNA를 분리한 우 DR β유전자를 소식자로 northem blotting을 하여 mRNA의 발현을 관찰하였으며, 말초혈액 백혈구와 갑상선 조직으로부터 분리된 DNA를 EcoRI BamHI. HindⅢ PvuⅡ TaqI, PstI등의 6가지 제한효소로 소화한 후 DR β유전자를 소식자로 하여 RFLP 양상을 비교한 결과, 환자 모두에서 mRNA의 발현이 관찰되었으나, 환자 모두에서 6가지 제한효소에 의한 RFLP 양상이 동일하였다. 이러한 결과는 Graves병 환자의 DR 유전자의 발현에 있어서 이 유전자 부위의 구조적인 변화가 관여할 가능성이 적음을 시사하는 사실이라고 사료되나 향후 더 많은 예와 더 많은 제한효소를 이용한 주시가 필요할 것이다. The requirement for major histocompatibility antigen class Ⅱ molecules in the recognition of antigen by helper T cells suggests that the expression of class Ⅱ antigen may be important in the initiation and prolongation of immunopathology. HLA class Ⅱ antigenes are expressed on the surface of thyrocytes of the patients with graves disease. The increased expression of class Ⅱgene can be induced by trans acting factor such as interferon However the possibility of rearrangement of their regulatory genes has not been explored so far. We studied the mRNA expression in the thyrocytes of 2 patients with Graves' disease and compared the restriction fragment length polymorphism (RFLP) between thyroid and peripheral leukocyte DNA. The prominent expression of mRNA was observed in the thyroid tissues of all the two patients. But we did not find any difference in RFLP pattern in both patients. These results suggest the possibility that the rearrangement of the regulatory gene located in the upstream of DR- β gene can be a role in expression of DR antigen is less likely.

Lee, Dahae,Lee, Dong-Soo,Jung, Kiwon,Hwang, Gwi Seo,Lee, Hye Lim,Yamabe, Noriko,Lee, Hae-Jeong,Eom, Dae-Woon,Kim, Ki Hyun,Kang, Ki Sung The Korean Society of Ginseng 2018 Journal of Ginseng Research Vol.42 No.1

Background: The aim of the present study was to evaluate the potential protective effects of six ginsenosides (Rb1, Rb2, Rc, Rd, Rg1, and Rg3) isolated from Panax ginseng against tacrolimus (FK506)-induced apoptosis in renal proximal tubular LLC-PK1 cells. Methods: LLC-PK1 cells were treated with FK506 and ginsenosides, and cell viability was measured. Protein expressions of mitogen-activated protein kinases, caspase-3, and kidney injury molecule-1 (KIM-1) were evaluated by Western blotting analyses. The number of apoptotic cells was measured using an image-based cytometric assay. Results: Reduction in cell viability by $60{\mu}M$ FK506 was ameliorated significantly by cotreatment with ginsenosides Rg1 and Rb1. The phosphorylation of p38, extracellular signal-regulated kinases, and KIM-1, and cleavage of caspase-3, increased markedly in LLC-PK1 cells treated with FK506 and significantly decreased after cotreatment with ginsenoside Rb1. The number of apoptotic cells decreased by 6.0% after cotreatment with ginsenoside Rb1 ($10{\mu}M$ and $50{\mu}M$). Conclusion: The antiapoptotic effects of ginsenoside Rb1 on FK506-induced apoptosis were mediated by the inhibition of mitogen-activated protein kinases and caspase activation.

Lee, Dahae,Kang, Ki Sung,Yu, Jae Sik,Woo, Jung-Yoon,Hwang, Gwi Seo,Eom, Dae-Woon,Baek, Seung-Hoon,Lee, Hye Lim,Kim, Ki Hyun,Yamabe, Noriko The Korean Society of Ginseng 2017 Journal of Ginseng Research Vol.41 No.3

Background: Compound FK506 is an immunosuppressant agent that is frequently used to prevent rejection of solid organs upon transplant. However, nephrotoxicity due to apoptosis and inflammatory response mediated by FK506 limit its usefulness. In this study, the protective effect of Korean Red Ginseng (KRG) against FK506-induced damage in LLC-PK1 pig kidney epithelial cells was investigated. Methods: LLC-PK1 cells were exposed to FK506 with KRG and cell viability was measured. Western blotting and RT-PCR analyses evaluated protein expression of MAPKs, caspase-3, and KIM-1. TLR-4 gene expression was assessed. Caspase-3 activities were also determined. The number of apoptotic cells was measured using an image-based cytometric assay. Results: The reduction in LLC-PK1 cell viability by $60{\mu}M$ FK506 was recovered by KRG cotreatment in a dose-dependent manner. The phosphorylation of p38, p44/42 MAPKs (ERK), KIM-1, cleaved caspase-3, and TLR-4 mRNA expression was increased markedly in LLC-PK1 cells treated with $60{\mu}M$ FK506. However, with the exception of p-ERK, elevated levels of p-p38, KIM-1, cleaved caspase-3, and TLR-4 mRNA expression were significantly decreased after cotreatment with KRG. Activity level of caspase-3 was also attenuated by KRG cotreatment. Moreover, image-based cytometric assay showed that apoptotic cell death was increased by $60{\mu}M$ FK506 treatment, whereas it was decreased after cotreatment with KRG. Conclusion: Taken together, these results suggest that the molecular mechanism of KRG in the FK506-induced nephrotoxicity may lead to the development of an adjuvant for the inhibition of adverse effect FK506 in the kidney.

This study was conducted to fine the adaptatbility of Korean Native Cattle lacking in the resistance ability to Theileriosis being occured by ticks born parasites in Cheju Island. Data used in this study were collected from none-treated and treated Thpileria sergenti blood vaccine to Korean Native Cattle, Cheju Native Cattle and Cheju Native CattlexBrahman crossbreds during the grazing season in 1988. The parasitemia level of Theileria sergenti in artificial immunized Korean Native Cattle were fewer than none-treated Korean Cattle's, due to immunizing effects. the RBC and PCV reduction were prevented, and average daily gain's 0.25kg in artificial immunized Korean Native Cattle was higher than those of 0.20kg in none-treated. The mortality numbers were one in artificial immunized Korean Native Cattle and four in none-treated Korean Native Cattle. The resistance ability of Theileriosis of Korean Native Cattle was the weakest and Cheju Native Cattle×Brah-man crossbred was the strongest among the breeds.

The objective of this study was to characterise the pattern of p53 mutations in bladder turmor. In this study, 25 bladder transitional cell carcinomas were analyed by immunohistochemistry (IHC) for p53 nuclear overexpression, and the results were compared with those of polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) analysis in exon 5-8 of the p53 gene and DNA sequencing analysis. 15 out of 20 cases (75%) showed p53 nuclear immunoreactivities on IHC. On PCR-SSCP analysis, 10 out of 25 cases(40%) had abnormal shifts on mobility. 62% of the mutations were in exon 8. Direct DNA sequencing analysis were performed in these 10 cases to confirm the presence of mutated p53 genes and to determine the type of mutations. Sixteen point mutations were detected in 10 cases. Tow specimens had double mutations and another two had triple mutations. G:C→A:T transitions were the most frequent patterns (62.5%). One mutation was a premature stop codon and two were silent mutations. There out of 10 had a point mutation at codon 285 (GAG/Glu→AAG/Lys) and two had at codon 280(GAG/Glu→AAG/Lys). One of 16 mutations was transition at hot spot codon 273 with CpG site. These results suggest that altered expressions and point mutations of p53 occured in all grade of bladder cancer, but are more associated with hight grade bladder tumors. To elucidate the carcinogenesis of bladder cancer, further studies should be carried out.
