        한방 이화주의 미백 및 피부 주름 개선 효과

        이상진(Sang-Jin Lee),권이영(Yi-Young Kwon),조성원(Sung-Won Cho),권희숙(Hee-Suk Kwon),신우창(Woo-Chang Shin) 한국식품영양과학회 2013 한국식품영양과학회지 Vol.42 No.4

        본 연구에서는 한방이화주의 피부 생리기능 활성을 알아보기 위해 70% EtOH 추출물의 피부 미백, 주름 개선 및 항염증 효과를 조사하였다. HEE은 tyrosinase 활성 억제 및 tyrosine을 기질로 melanin이 형성되는 pathway에 관여하는 주요한 인자인 TRP-1과 TRP-2를 저해하는 작용 기전을 통해 피부 색소침착의 주요 원인 물질인 melanin 생합성을 농도 의존적으로 저해하는 것을 확인하였다. HEE은 피부진피 내 피부 탄력을 유지하는 elastin을 분해하는 효소인 elastase의 활성을 저해하였고, 피부의 keratinocyte가 생성분비하는 MMP-2와 MMP-9의 단백질 발현과 proteolytic 활성을 억제하여 노화에 따른 피부 주름 생성 억제할 수 있는 가능성을 확인하였다. 또한 세포 독성 없이 LPS에 의해 유도된 염증 반응을 50% 저해하는 HEE의 농도(IC50)는 24.9 μg/mL이며, 50 μg/mL 농도로 처리하였을 때 염증 반응 저해 효과가 70%로 높은 효과를 가지는 것을 확인하였다. 이상의 결과를 종합하면 HEE의 피부 미백, 주름 개선 및 항염증에 우수한 효과를 나타내고 있으므로 기능성 화장품의 주요한 소재로 이용 가치가 높을 것으로 사료된다. Extrinsic skin aging is characterized by the loss of skin tone and resilience, irregular pigmentation, and deep wrinkles. The aim of this study was to investigate the effects of Ehwa Makgeolli containing oriental herbs (Glycyrrhiza uralensis Fisch., Lycium chinense MILL., Morus alba L., and Saururus chinensis Baill) on skin whitening and wrinkling in human skin cells. We prepared Makgeolli extracts (HEE) with 70% ethanol. HEE significantly inhibited in vitro mushroom tyrosinase activity and reduced the cellular and secreted melanin content of mouse melanoma melanocytes (B16F1 cells). HEE down-regulated the protein expression of tyrosinase related protein (TRP)-1/-2, a key player in melanogenesis. Treatment with HEE in human keratinoctyes (HaCaT cells) inhibited the proteolytic activities of matrix metalloproteinase (MMP)-2/-9 in a dose-dependent manner and dramatically reduced the expression of MMP-2/-9. In addition, HEE attenuated lipopolysaccharide (LPS)- induced nitric oxide production in murine macrophages (RAW264.7 cells). These results indicate that HEE may be a great cosmeceutical ingredient for its whitening, anti-wrinkle, and anti-inflammatory effects.

        Genetic Characterization of Haemagglutinin 1 Domain of Influenza B Viruses Isolated in Korea during $1988{\sim}1999$

        Shin, Gu-Choul,Na, Byoung-Kuk,Lee, Joo-Yeon,Ahn, Jung-Bae,Park, Jong-Won,Lee, Jin-Soo,Kim, Jee-Hee,Kim, Woo-Joo,Kang, Chun The Korean Society for Microbiology 2003 Journal of Bacteriology and Virology Vol.33 No.4

        Although Korean influenza virus isolates have been genetically associated with the vaccine strains of the corresponding year, influenza B viruses have prevailed almost every year in Korea during the past decades. We have 'analyzed the genetic characteristics and evolutionary patterns of the haemagglutinin (HA) 1 domains of influenza B viruses isolated during 1988-1999 using direct RT-PCR and sequencing. Phylogenetic analysis of influenza B viruses isolated in Korea indicated that antigenically and genetically distinguishable strains of the lineage II and lineage III variants had been cocirculated. Variants prevailed in early 1990s are represented in 1996/97 and 1998/99 and some different variants have been co circulated geographically and prevailed concurrently in Korea. All HA1s of Korean isolates have amino acid substitutions mainly in the region between position 124 and 310, which was previously proposed an immunodominant region. Insertion-deletion patterns of the HA gene revealed that Korean influenza B viruses were evolved from Lee40 with different manner between lineage II and III viruses. Lineage III viruses were also divided into two groups as conserved group and inserted group, in relation to Lee40. But lineage II viruses had evolved with directional pattern. Antigenic index proposed that influenza B isolates prevailed since 1996/97 seasons might had emerged from the antigenic variants of a Seo1697-like virus and that new variants might appear from the lineage II viruses resulting in persistent prevalence in Korea.

      • 성인에서 Haemophilus influenzae 감염증의 임상양상과 미생물학적 특성

        이종섭,황병연,정희진,김우주,박승철,이도현,이창규,신종희,황규잠,이영희 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.2

        목적 : H. influenzae는 성인에서 흔히 호흡기 감염을 일으키는 균주로, 최근 ampicillin 내성 β-lactamase 생성 균주들이 지속적인 증가를 보이고 있어, 이에 국내 성인에서 H. influenzae에 의한 감염의 임상양상과 분리된 균주들의 미생물학적 특성을 조사하고자 하였다. 방법 : 1998년 3월부터 1999년 9월까지 고려대 구로병원에 내원한 환자중에서 H. influenzae가 분리된 68명을 대상으로 임상양상을 조사하고 항균제 감수성 검사를 시행하였다. 분리된 33주에 대해서 혈청형, 생물형, 세포외막 단백분석을 시행하였고, β-lactamase 생성여부에 따른 감염 환자군간 임상상 및 예후의 차이를 비교하였다. 결과 : 환자의 평균연령은 68세였고, 지역사회 획득감염이 전체의 85%를 차지하였다. 폐렴과 기관지염과 같은 하기도 감염이 전체환자의 75%를 차지하였고 분리 검체 역시 객담이 84%로 가장 많았다. 환자의 71%가 기저질환을 가지고 있었으며, 그 중에 만성 폐쇄성 폐질환, 심혈관 질환, 악성종양, 당뇨병이 대부분이었다. 혈청형으로는 nontypeable 형이 68%로 가장 많았고 b형은 한 예도 없었다. β-lactamase 생성율은 63.2%였고, β-lactamase 양성균주의 항균제 내성율이 음성균주에 비하여 높았으나 β-lactamase 생성 여부에 관계없이 cefotaxime, azithromycin, ciprofloxacin에 대하여 100%의 감수성을 나타내었고 cefaclor, cefuroxime에 대해서는 10% 이하의 낮은 내성율을 보여 이들 항균제들이 치료에 효과적일 것으로 사료된다. 세포외막 단백분석에서는 C형과 D형이 전체의 64%로 가장 많았으며, 혈청형과의 유의한 연관성은 보이지 않았다. 결론 : 성인에서 H. influenzae는 주로 만성 기저질환자에서 급성 호흡기감염 또는 만성 폐쇄성 폐질환의 급성 악화를 유발한다. 기존의 보고에 비해 β-lactamase 양성율이 증가하였고, 이에 따른 항균제 내성율도 증가하여 항균제의 선택에 유의하여야 할 것으로 생각된다. 세포외막 단백분석상 특정한 유형의 균주에 의해 감염이 집중적으로 발생하고 있어 향후 역학 조사의 도구로 이용할 수 있겠다. Purpose : H. influenzae is one of the common causative microorganisms of respiratory tract infections in adults. Recently. β-lactamase producing, ampicillin-resistant H. infiuenzae has become worldwide problem as well as in Korea. We studied to investigate the clinical features and microbiologic characteristics of H. infiuenzae infections in adults. Materials & Methods : From March 1998 to September 1999, 68 patients were enrolled in this study. Clinical features of H. infiuenzae infections were investigated, 68 isolates were subjected to the β-lactamase test, and 33 isolates were used for serotyping. biotyping, antibiotic susceptibility and outer membrane protein (OMP) analysis. Results : Mean age of study patients was 68 years-old and the acquisition rate in community was 85%. Pneumonia and bronchitis were the most common type of infection such as 80%, sputum was the most common clinical specimen for H. mQuenzae isolation. 70% of patients had chronic underlying diseases. Non-typeable strains were 68% and β-lactamase producing rate was 63%. There was no difference in the clinical features and prognosis of H. influenzae infection between the β-lactamase positivie and -negative groups. The susceptibility of cefotaxime, azithromycin, and ciprofloxacin was 100% and that of cefaclor, cefuroxime was under 10% in spite of β-lactamase positivity. In OMP analysis, C and D types were dominant (64%). Conclusion : H. influenzae caused acute respiratory infections in adults with chronic underlying disorders. This study shows higher β-lactamase producing rate and antibiotic-resistance rate than that were reported previously. OMP analysis shows that two major types of strains cause clinical infections intensively.

      • 한국인에게서 그레이브스병 약물치료의 적정기간

        이형숙,이동훈,정희선,이종우,김정은,신승수,정윤석,이관우,김현만 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.1

        연구배경: 그레이브스병의 치료에는 항갑상선제, 수술 및 방사성 요오드법이 선택되어 사용되고 있다. 이중 항갑상선제는 가장 많이 선호되고 있으나 낮은 관해율과 높은 재발율로 장기간 치료기간이 요구된다. 저자들은 그레이브스병 환자에게서, 선택되는 치료법의 선호도와 각 치료법의 관해율을 조사하고자 본 연구를 시행하였다. 또한 본 연구에서는 항갑선제 치료의 적정기간을 평가하고자 하였다. 방법: 아주대학교병원에 내원한 환자 중 1년 이상 추적관찰이 가능한 205명의 그레이브스병 환자를 대상으로 조사하였다. 항갑상제군, 수술군 및 방사성 요오드군은 각각 170명, 29명 그리고 6명이었다. ROC curve를 이용하여 약물치료의 예후예측인자를 분석하였다. 결과: 1) 그레이브스병 환자의 치료 방법의 선택은 항갑상선제군, 수술군 및 방사성 요오드군 각각 170명(83.0%), 29명(14.1%) 그리고 6명(2.9%)으로 항갑상선제 치료가 가장 선호되었다. 2) 그레이브스병의 관해율은 항갑상선제군, 수술군 및 방사성 요오드군에서 각각 60.0%(102/170명), 96.5%(28/29명) 그리고 83.0%(5/6명)으로 수술군이 가장 높았다. 3) ROC curve의 AUC는 치료기간과 진단시 TBII가 각각 0.709 및 0.648이었고 적절한 약물투여 추적 관찰기간은 26개월이었다. 결론: 그레이브스병의 일차 치료법으로는 항갑상선제가 선호되고 있으나 수술 및 방사성 요오드 치료군에 비해 상대적으로 낮은 관해율을 보였다. 따라서 항갑상선제 치료로 26개월 이상 관해가 되지 않을 경우에는 치료 방법의 변경을 고려하는 것이 관해율을 높이는데 도움이 될 것으로 생각된다. Background: Graves' disease in an organ specific autoimmune disease. Three kinds of therapeutic modalities (antithyroid drugs, ablation with radioactive iodine and subtotal thyroidectomy) are frequently performed for the management of this disease. The most popular therapeutic policy for the disease in Korea is antithyroid treatment. We analysed and compared the remission rates of all three modalities for Graves' disease, and evaluated the antithyroid modality to determine the correct duration of treatment. Subjects & Methods : The medical records of 205 patients with Graves' disease were reviewed. For the evaluation of the antithyroid modality medical treatment, antithyroid drugs were administered for more than 1 year. The prognostic factors associated with remission were analysed by means of an ROC curve. Results: 1) Of the 205 patients, proportions that received medical therapy, subtotal thyroidectomy and radioiodine therapy were 83.0, 14.1 and 2.9%, respectively. 2) The remission rates of the medical therapy, surgery and radioiodine therapy were 60.0, 96.5 and 83.0%, respectively. 3) The remission rate of the medical therapy was associated with the duration of medication and TBII activity. The determined proper duration for the antithyroid treatment was 26 months from the ROC curve analysis. Conclusion: The above results suggest that the proper duration of antithyroid treatment for Graves' disease is 26 months, after which time the subtotal thyroidectomy or radioiodine therapy should be considered if the disease has not remitted (J Kor Soc Endocrinol 18:24∼31, 2003).

      • Plenary Session 2 : PS-2-1 ; Outcomes of hepatitis B virus recurrence after liver transplantation: a multicenter analysis in Korea

        ( Hee Yeon Kim ),( Jong Young Choi ),( Dong Goo Kim ),( Myoung Soo Kim ),( Soon Il Kim ),( Shin Hwang ),( Sung Gyu Lee ),( Kwang Woong Lee ),( Kyung Suk Suh ),( Young Seok Han ),( Dong Lak Choi ),( Se 대한간학회 2012 춘·추계 학술대회 (KASL) Vol.2012 No.-

        Background: The outcome of hepatitis B virus (HBV) infection after liver transplantation (LT) was improved by hepatitis B immunoglobulin (HBIG) and nucles(t)ide analogue (NUA). However, HBV recurrence after LT is critical because the recurrence is occasionally accompanied by a progressive destruction of graft and poor survival. The aims of this study were to investigate the significance HBV recurrence and identity factors associated with HBV recurrence. Methods: From October 1999 to February 2011, a total of 2684 consecutive LT recipients who underwent HBV-associated LT were retrospectively enrolled from 7 transplantation centers in Korea. Results: Prophylaxis regimens were HBIG monotherapy (67.7%) or a combination of HBIG with NUA (22.3%). The recurrence rate of HBV was 6.1% (164 recipients) during mean follow-up duration of 10.9 years. The median time from transplantation to recurrence was 2.1 years (0.1-7.9 years). Of the 1,071 patients with hepatocellular carcinoma (HCC) prior to LT, 155 patients (14.5%) had HCC recurrence after transplantation, and 48 patients (31.0%) had HBV recurrence. Of the 48 patients with recurrence of both HBV and HCC, 25 patients (52.1%) experienced HBV recurrence after HCC recurrence. In the multivariate analysis, pretransplant HCC, pretransplant HBV DNA above 5.5 log copies/mL was independent clinical factors influencing HBV recurrence after LT. The mortality rate among the recipients with HBV recurrence was 34.1% (56 recipients). Mean overall survival was 6.4 years in the HBV-recurrence group and 9.9 years in the HBV-nonrecurrence group (p<0.001). HBV recurrence was not an independent prognostic factor for overall survival. HCC recurrence was the most important factor for overall survival. Conclusions: The overall outcome of LT in HBV-related liver disease was excellent with the current prophylaxis regimen Choon Hyuck David Kwon,8 Suk-Koo Lee8 Pretransplant HBV DNA and HCC were important factors for HBV recurrence. HBV recurrence after LT did not significantly influence on the overall survival without combining of HCC recurrence.

        조혈모세포이식 환자에서 발생한 Cytomegalovirus 질환의 특징 : 일개 대학변원에서 최근 10년간의 경험

        최수미,이동건,박선희,김시현,김유진,민창기,김희제,이석,최정현,유진홍,김동욱,이종욱,민우성,신완식,김춘추 대한감염학회 2009 감염과 화학요법 Vol.41 No.1

        Background : Studies on cytomegalovirus (CMV) diseases in Korean hematopoietic stem cell transplant (HSCT) recipients are lacking and do not reflect the recent trends of advances and changes. Therefore, we tried to analyze the clinical features of CMV diseases in HSCT recipients over the past 10 years at a tertiary university hospital in Korea. Methods : Retrospective review of medical records was done for all adult HSCT patients who received transplant at the Catholic HSCT Center from January 1998 to January 2008. Results : Forty-four cases (2.2%) of CMV diseases were identified. CMV pneumonia was diagnosed in 17 patients, retinitis in 16 patients, enterocolitis in 7 patients, esophagitis 1 patient, gastritis in 1 patient, duodenitis in 1 patient, and hepatitis in 1 patient. The median onset of symptom was 90 days after transplantation. Late CMV diseases accounted for 47.7%. CMV related death varied from 0 to 58.8% according to the involved organ. CMV retinitis was diagnosed relatively later in the course of transplantation mostly in patients who had chronic graft versus host disease (GVHD). On the contrary, CMV enterocolitis mainly occurred in patients who suffered from acute GVHD. The overall concurrent CMV reactivation was documented to be 63.6%: the concurrent CMV reactivation was observed only in 37.5% of patients with retinitis. Conclusions : We observed some differences in the pattern of CMV disease manifestation according to the involved organ and reconfirmed the fact that CMV pneumonia is the most common and fatal disease in HSCT recipients. Additionally, CMV retinitis was not uncommon in HSCT recipients. Since specific marker does not exist in predicting retinitis, regular ocular examination should be done thoroughly, especially in patients with chronic GVHD.

      • Interferon-gamma 투여에 의한 Toxoplasma 감염 마우스의 면역학적 변화

        이영하,신대환,심희숙 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.1

        This study was performed to evaluate differences of immune responses according to the injection period of recombinant mouse interferon-γ(IFN-γ) in acute murine toxoplasmosis. Each mouse was infected intraperitoneally with 100 cysts of Beverley strain of T. gondii, and injected with 5 × 10 ^4 units of IFN-γ every other day for a total of two injections. From the 1st week after infection, blastogenic responses of splenocytes to concanavalin A(Con. A, 2.5㎍/ml) and Toxoplasma antigen(30.0㎍/ml) were examined at 1 week interval for 4 weeks. Also serum IgG and IgM antibody titers were examined by enzyme-linked immunosorbent assay, and immunohistochemical study of brain tissues were done at the same time. Toxoplasma antigen-treated blastogenic responses were significantly increased in the IFN-γ injected groups as compared with Toxoplasma-infected group. However Con. A-treated blastogenic responses were increased in the mice that received two doses of IFN-γ on day 4 and 2 before infection, or day 2 and 0 before infection. The serum IgG and IgM antibody titers of IFN-γ injected groups were increased from 2 weeks after infection, and IgM antibody titers were increased at 2 and 3 weeks after infection as compared with non-infected group. No significant differences were revealed between IFN-γ injected groups and Toxoplasma-infected group. T gondii was found as tachyzoites at 2 weeks after infection, and cysts found in 4 weeks. However, no T. gondii was detected in IFN-γ injected groups in the same period. The results suggested that IFN-γ administration to T. gondii-infected mice improve the cell-mediated immune responses, especially when IFN-γ was injected just before T. gondii infection. But there was not significant differences serum antibody titers and immunohistochemical findings of brain tissues according to the injection period of IFN-γ.

        Accessory breast tissue is developed from persistence of breast tissue along the milk line which first beomes apparent at the 6th week of embryo and usually atrophies except for the thoracic area until the 9th week. It is much more common than amastia and occurs in approximately from 2 to 6 percent of the population. But multiple polymastia involving labia major is quite rare. We experienced one case of multiple polymastia involving labia majora & both axilla and 6 cases of polymastia & polyhelia, so we are willing to report our cases with a review of literature.
