목적 : Inhibin은 α-subunit와 β-subunit로 구성된 이질 이량체의 당단백으로 β-subunit의 차이에 의해 inhibin A (α-βA)와 inhibin B (α-βA)로 구분된다. 여성에서 inhibin은 주로 난소의 과립막세포 및 황체에서 생산되어 뇌하수체의 FSH 분비를 억제한다고 알려져 왔으나, 임신중 태반과 남성의 고환에서도 생산된다는 사실이 밝혀져 다양한 생리적 작용이 추정되고 있으며 최근에 inhibin A와 B를 분리 측정할 수 있는 방법이 개발되어 inhibin에 대한 연구가 활발히 진행되고 있다. 이에 저자들은 정상 월경주기를 가진 가임기 여성, 폐경이행기 여성, 폐경후기 여성에서 inhibin A와 inhibin B의 농도를 측정하여 월경주기에 따른 정상치의 변화와 노화에 따른 농도 변화를 관찰하고, 난소에서 면역조직화학적 염색법으로 inhibin A와 inhibin B의 발현 양상과 변화를 비교 관찰하여 inhibin의 정확한 생리작용, 폐경이행기에서 inhibin의 역할 및 폐경이행기와 폐경의 예측 지표의 사용 가능성을 알아보고자 하였다. 연구 방법 : 월경주기와 난소기능이 정상이면서 난소종양이 없는 정상 가임기 여성 160명, 폐경이행기 여성 60명, 폐경후기 여성 20명에서 정맥혈을 채혈하여 혈중 inhibin A와 inhibin B 농도를 ELISA로 측정하였고, 그중 정상 가임기 여성 35명, 폐경이행기 여성 20명, 폐경기 여성 5명의 난소 조직을 inhibin α, βA 및 βB subunit에 대한 단클론 항체를 이용하여 면역조직화학적 염식을 시행하였다. 결과 : 1. 정상 가임기 여성에서 혈중 inhibin A 농도는 중증식기까지 낮은 농도를 유지하다 후증식기 (16.53±1.57 pg/ml)부터 증가하기 시작하여, 중분비기 (45.85±2.08 pg/ml)에 최고치에 이른 후 서서히 감소하는 경향을 보였다. Inhibin B 농도는 전증식기 (65.40±4.08 pg/ml)부터 증가하기 시작하여 증식기 동안 계속 높은 농도를 유지하다가 배란기 (110.74±9.83 pg/ml)에 최고치에 이른 다음 분비기에 급격히 감소하였다. 2. 폐경이행기 여성에서 혈중 inhibin A 농도는 증식기에 6.68±0.53 pg/ml, 분비기에 21.78±3.61 pg/ml로 모두 정상 가임기 여성과 비교하여 유의하게 낮았다 (P<0.01). Inhibin B의 농도는 증식기에 52.16±7.46 pg/ml, 분비기에 22.41±6.73 pg/ml로 모두 정상 가임기 여성과 비교하여 유의하게 낮았다 (각각 P<0.01, P=0.025). 3. 폐경후기 여성에서 inhibin A와 inhibin B 농도는 모두 검출되어 않았다. 4. 정상 가임기 여성에서 inhibin α subunit의 면역염색반응은 과립막세포, 난포막세포 및 황체에서 강하게 발현되었다. Inhibin βA의 면역염색반응은 난포에서는 거의 발현되지 않았으나 황체에서는 관찰되었다. Inhibin βB의 면역염색반응은 일차난포에서 처음 발현되어 성장난포와 성숙난포의 과립막세포와 난포막세포에서 관찰되었으나 Inhibin α보다는 약했고 황체에서는 거의 관찰되지 않았다. 5. 폐경이행기 여성에서 inhibin subunit들의 면역염색반응은, 정상 가임기 여성과 같은 양상으로 발현되었으나, 발현정도는 약했다. 모든 면역염색반응은 과립막세포보다 난포막세포에서 더 강하게 나타났다. 6. 폐경후기 여성에서 inhibin subunit들의 면역염색반응은 전혀 관찰되지 않았다. 결론 : Inhibin A는 후증식기 성숙난포에서 처음 생산되기 시작하여 배란 후 황체에서 주로 생산되며, Inhibin B는 일차난포에서 생성되기 시작하여 배란 시까지 분비되므로 inhibin A는 황체기능을, inhibin B는 난포의 기능을 반영한다. 폐경이행기가 되면 inhibin A와 B의 분비는 급속히 감소하게 되어 폐경 후에는 난소에서 생성되지 않는다. 따라서 inhibin A와 B는 여성의 월경주기에 따라 생산과 분비가 서로 다른 호르몬으로 난자 성숙과 난포발달에 관여하며, 난소의 노화 정도를 측정하는 폐경이행기의 지표로 이용될 수 있을 것이다. Objective : To understand the physiologic effects and secretion pattern of inhibin A and inhibin B during menstrual cycle and menopausal transition, inhibin A and inhibin B levels were measured. And to detect any changes in expression of inhibins in human ovary with age, we examined immunohistochemical staining of α, βA, and βB subunits of inhibin in ovarian tissues. This study was also designed to investigate whether or not inhibin is an early marker for menopausal transition. Methods : Inhibin A and inhibin B levels were measured in 320 samples from normal reproductive women, in 60 from perimenopausal women, and in 20 from menopausal women by ELISA. And we examined the immunohistochemical staining of α, βA, and βB subunits of inhibin in ovarian tissues of 35 normal reproductive, 20 perimenopausal, and 5 menopausal women, respectively. Results : In the normal reproductive women, inhibin A begins to increase in the late proliferative phase (16.53±1.57 pg/ml), reaches the peak in the mid-secretory phase (45.85±2.08 pg/ml), reaches the peak in the ovulatory phase (110.74±9.83 pg/ml), reaches the peak in the ovulatory phase (110.74±9.83 pg/ml), and thereafter declines rapidly. In the perimenopausal women, mean inhibin A serum concentration was 6.68±0.53 pg/ml during proliferative phase and 21.78±3.61 pg/ml during secretory phase, which were significantly lower than that of the same phase in the normal reproductive women (P<0.01). Mean inhibin B serum concentration was 52.16±7.46 pg/ml during proliferative phase and 22.41±6.73 pg/ml during secretory phase, which were significantly lower than that of the same phase in the normal reproductive women (P<0.01, P=0.025). In the menopausal women, both inhibin A and inhibin B were not detected. In the normal reproductive women, we observed strong immunostaining for α subunit in granulosa cells, theca cells, and corpus luteum. Immunostaining for βA subunit was observed in corpus luteum, but not in growing follicles. Immunostaining for βB subunit was observed in primary follicle, granulosa and theca cells of growing follicle, and mature follicle, but less strong than immunostaining for α subunit. No staining for βB subunit was observed in the corpus luteum. In the perimenopausal women, immunostaining for inhibin subunits were observed in the same pattern as that of the normal reproductive women, but weaker. Stronger immunostaining was observed in theca cells than granulosa cells. In the menopausal women, none of the immunostaining of inhibin subunits were observed.

무당벌레(H. axyridis)는 세계적으로 진딧물의 포식자로 널리 알려지면서 농생태계내에서 진딧물을 방제하기 위한 방제인자로 많이 사용하고 있다. 또한 국내에서는 농약의 사용을 억제하는 정부정책과 소비자의 요구 등으로 인하여 친환경농업이 확대되면서 친환경농자재들이 많이 사용되고 있다. 따라서 친환경농자재의 사용은 무당벌레에 직간접적으로 영향을 미칠 수가 있다. 살충성친환경농자재(IEFAMs)의 경우 무당벌레의 각 발육단계에 대하여 대부분 안전한 경향을 나타내고 있다. 살균성친환경농자재(FEFAM)의 경우에도 FEFAM A를 제외한 다른 종류들은 무당벌레에 대하여 영향이 적다. 토양미생물친환경농자재(EFAMSM)인 EFAMSM C와 H는 무당벌레 알의 부화율을 떨어뜨릴 수가 있으며, EFAMSM A와 F는 1령 유충에 피해를 줄 수 있는 것으로 조사되었다. 식물성추출물친환경농자재(EFAMPE)는 EFAMPE A와 D는 무당벌레 알에 치명적인 독성을 보이고 있는 것을 알 수 있다. 그 이외의 다른 조사된 농자재들은 무당벌레에 비교적 독성이 약한 것으로 평가되었다. The multicolored Asian ladybird beetle (Harmonia axyridis) has been commonly used with biological control agents for control of several kinds of aphids in agroecosystems. Also, environment friendly agricultural materials have been commonly applied in crop fields because the government held down pesticide application and environment friendly agricultures are gradually increased with consumer's desires. The multicolored Asian ladybird beetles may be directly or indirectly under the influence of environment friendly agricultural materials In crop fields. The insecticidal environment friendly agricultural materials (IEFAMs) might be saff against each developmental stage of multicolored Asian ladybird beetle. Fungicidal environment friendly agricultural materials (FEFAMs) had a miner effect to each developmental stage of multicolored Asian ladybird beetle with the exception of FEFAM A. Environment friendly agricultural materials contained useful soil microorganisms (EFAMSMs) C and H might be down the hatching rate of eggs, and EFAMSM A and F had a killing effect to 1st instar of lady beetles. Environment friendly agricultural materials contained plant extracts (EFAMPEs) A and D might be suffered effect a deathblow of egg hatching with lady beetles. Otherwise, there was a miner effect to lady beetles with the rest of tested environment friendly agricultural materials.

( Mi-jin Lee ),( Goung-ran Yu ),( Hua Lee ),( Yun-a Kim ),( Jun Zhang ),( Dae-ghon Kim ) 대한간학회 2016 춘·추계 학술대회 (KASL) Vol.2016 No.1

Aims: Erythropoietin-producing hepatocellular receptor tyrosine kinase subtype A2 (EphA2) is an attractive therapeutic target for suppressing tumor progression. EKI1 is coordination complex of zinc and known for its use in treating dandruff and seborrhoeic dermatitis. The aim of this study is to discover novel small molecules to inhibit EphA2 for the treatment of hepatocellular carcinoma and cholangiocarcinoma. Methods: To discover novel and potent EphA2 inhibitors, we performed HTRF (Homogeneous time resolved fluorescence) kinase assay using the chemical library of Korea Chemical Bank and primary screened novel hit compounds. The enhancement of EKI1-mediated apoptosis and autophage were examined using immunoblotting and FACS analysis. Additionally, the antitumor effect of EKI1 was assessed using a mouse model. Results: Thirty-six compounds screened as EphA2 kinase inhibitor by HTRF assay. We validated these substances related to inhibit cell proliferation and cell death. We identified EKI1, a effective theranostics based small molecules. Human hepatocellular carcinoma cell line and cholangiocarcinoma cell lines were treated various concentration of EKI1 for 12h. At low concentration of EKI1, proliferation of these cells was inhibited. At high concentration of EKI1, cell death was induced in these cells. As quantitatively assessed by flow cytometry, apoptosis was induced by EKI1 in cells. We investigated apoptotic signaling by Western blot and observed cleavage or overexpression of pro-caspase-7 and PARP in EKI1 treated cells compared with vehicle. The anti-proliferation effect of EKI was due to an increased autophage, which was confirmed by up-regulation of Autophagy protein 5 (Atg5), BECN and LC3 (autophagosome marker). In addition, EKI1 induced reactive oxygen species (ROS) in JCK and Huh7. We examined EKI1 up-or down-signal transduction pathways to use therapeutic target for HCC and CC. In vivo mouse model, tumor growth was suppressed in EKI1 injected mouse group compared with control group. Conclusions: Our results revealed that autophage and apoptosis are involved in EKI1-mediated tumor cell death. Therefore, the EphA2 kinase inhibitor EKI1 is therapeutic target for hepatocellular carcinoma and cholangiocarcinoma.

( A Ra Shim ),( Yu Im Hwang ),( Kyung Jin Lim ),( Young Mi Choi ),( Young Eun Jeon ),( Seok Kyo Seo ),( Si Hyun Cho ),( Young Sik Choi ),( Byung Seok Lee ) 대한산부인과학회 2011 Obstetrics & Gynecology Science Vol.54 No.11

Objective To evaluate the clinical, hormonal and metabolic characteristics according to luteinizing hormone (LH)/follicle stimulating hormone (FSH) ratio in women with polycystic ovary syndrome (PCOS). Methods A total of 225 women with PCOS were included in this study. They were divided into two groups according to LH/FSH ratio; group A (LH/FSH < 2, n=160) and group B (LH/FSH > 2, n=65). We compared clinical, hormonal and metabolic characteristics including age at menarche, body mass index (BMI), blood pressures, ovarian volume, and serum androgen levels between the two groups. Serum glucose and insulin levels, fasting glucose/insulin ratio, homeostatic model assessment of insulin resistance (HOMA-IR), and lipid profi les were also compared between the two groups. Pearson correlation coeffi cients were used to evaluate correlation between the LH/FSH ratio and various parameters. Results Age of menarche in the group B was signifi cantly later than that in the group A. BMI, waist-hip ratio and blood pressures were signifi cantly lower in the group B compared to those of the group A. Ovarian volume and serum levels of LH, estradiol, total testosterone, sex-hormone binding globulin, 17-hydroxyprogesterone (OHP), and high density lipoprotein were signifi cantly higher in the group B. Postprandial 2 hours glucose, insulin and HOMA-IR were signifi cantly higher in the group A. After adjustment of BMI, the LH/FSH ratio was signifi cantly positively correlated with age at menarche, ovarian volume, total testosterone levels, and 17-OHP levels. Conclusion The inappropriate gonadotropin secretion may be negatively correlated with BMI, and positively with age of menarche and increased ovarian androgen production irrespective of BMI in women with PCOS. However, it may not be associated with metabolic characteristics.

오희정,유민아,이영숙,김미연,김승정,강덕희,윤견일,최규복,성순희 이화여자대학교 의과대학 2004 EMJ (Ewha medical journal) Vol.27 No.1

Dense deposit disease (DDD), known as type Ⅱ MPGN, is an uncommon form of glomerulonephritis. It is an acquired primary glomerular disease, characterised by electron microscopic evidence of a continous, dense membrane deposition replacing the lamina densa. There is associated alternative pathway complement activation and a C3 nephritic factor maybe present. Patients with dense deposit disease tend to be young at clincal onset and more commonly have persistent nephrotic syndrome, gross hematuria, and acute nephritis episode and persistent depression of the serum complement level. The prognosis of dense deposit disease is worse than that of typeⅠMPGN. We experienced a patient with dense deposit disease that presenting persistent nephrotic syndrome, gross hematuria and having subepithelial hump. It is a first report of dense deposit disease having subepithelial hump in Korea, therefore we report this case with the review of relevant literatures.

( Min-hye Jeong ),( Jung A. Kim ),( Seogchan Kang ),( Eu Ddeum Choi ),( Youngmin Kim ),( Yerim Lee ),( Mi Jin Jeon ),( Nan Hee Yu ),( Ae Ran Park ),( Jin-cheol Kim ),( Soonok Kim ),( Sook-young Park ) 한국균학회 2021 Mycobiology Vol.49 No.5

An endolichenic fungus Xylaria grammica EL000614 produces grammicin, a potent nematicidal pyrone derivative that can serve as a new control option for root-knot nematodes. We optimized an Agrobacterium tumefaciens-mediated transformation (ATMT) protocol for X. grammica to support genetic studies. Transformants were successfully generated after co-cultivation of homogenized young mycelia of X. grammica with A. tumefaciens strain AGL-1 carrying a binary vector that contains the bacterial hygromycin B phosphotransferase (hph) gene and the eGFP gene in T-DNA. The resulting transformants were mitotically stable, and PCR analysis showed the integratin of both genes in the genome of transformants. Expression of eGFP was confirmed via fluorescence microscopy. Southern analysis showed that 131 (78.9%) out of 166 transformants contained a single T-DNA insertion. Crucial factors for producing predominantly single T-DNA transformants include 48 h of co-cultivation, pretreatment of A. tumefaciens cells with acetosyringone before co-cultivation, and using freshly prepared mycelia. The established ATMT protocol offers an efficient tool for random insertional mutagenesis and gene transfer in studying the biology and ecology of X. grammica.

김진구,서미아,이유경,이선희 服飾文化學會 1996 服飾文化硏究 Vol.4 No.1

The elderly population of Korea has been significantly increasing due to advances in public health, medical care, and quality of life. Social and economic influence of the elderly population has been also increasing. As elderly people become more interested in their appearance and clothing than before, clothing plays an important role in the elderly women's everyday life. The objectives of the research are to explore the life satisfaction, appearance satisfaction clothing satisfaction, and clothing design preferance of 416 women aged 55 years and older who were residents of Seoul. Data were gathered through survey using a self-administered questionnaire from November, 1994 to January, 1995 in 8 senior schools and 3 senior centers which were scattered in Seoul. Descriptive statistics, t-test, and factor analysis were used in analysing the data. The results of this study indicate that life satisfaction have a positive relationship with clothing satisfaction. The respondents were divided into two groups by life satisfaction. The higher life satisfaction group prefered skirts and formal wear to the lower. But, two groups did not show any significant differences in terms of the color preference, motif preference, and fabric preference. The result of factor analysis divided appearance satisfaction into body satisfaction and face satisfaction. Body satisfaction had a positive relationship with clothing satisfaction. And the group of lower physical satisfaction showed lower satisfaction in apparel fitness. Also the face satisfaction had a positive relationship with clothing satisfaction. The group of higher physical satisfaction prefered skirts and formal wear compared to that of lower physical satisfaction. The color preference and motif preference between two group showed no significant difference. And the group of higher physical satisfaction prefered fabric that enhances the clothing style. Also, the group of higher face satisfaction prefered fabric that enhances the clothing style. However, there was no significant difference in the color preference and motif preference between two groups. The findings of this study may contribute to knowledge about clothing satisfaction and preference of elderly women in Seoul since there have been few studies, and be useful to apparel manufacturers as well as clothing researchers. Also, research subjects of this study could be extended to aged men and various regions.
