        Identification of Differentially Expressed Genes in Bovine Follicular Cystic Ovaries

        Choe, Chang-Yong,Cho, Young-Woo,Kim, Chang-Woon,Son, Dong-Soo,Han, Jae-Hee,Kang, Da-Won The Korean Society of Pharmacology 2010 The Korean Journal of Physiology & Pharmacology Vol.14 No.5

        Follicular cystic ovary (FCO) is one of the most frequently diagnosed ovarian diseases and is a major cause of reproductive failure in mammalian species. However, the mechanism by which FCO is induced remains unclear. Genetic alterations which affect the functioning of many kinds of cells and/or tissues could be present in cystic ovaries. In this study, we performed a comparison analysis of gene expression in order to identify new molecules useful in discrimination of bovine FCO with follicular cystic follicles (FCFs). Normal follicles and FCFs were classified based on their sizes (5 to 10 mm and $\geq25mm$). These follicles had granulosa cell layer and theca interna and the hormone $17{\beta}$-estradiol ($E_2$)/ progesterone ($P_4$) ratio in follicles was greater than one. Perifollicular regions including follicles were used for the preparation of RNA or protein. Differentially expressed genes (DEG) that showed greater than a 2-fold change in expression were screened by the annealing control primer (ACP)-based PCR method using $GeneFishing^{TM}$ DEG kits in bovine normal follicles and FCFs. We identified two DEGs in the FCFs: ribosomal protein L15 (RPL15) and microtubule-associated protein 1B (MAP1B) based on BLAST searches of the NCBI GenBank. Consistent with the ACP analysis, semi-quantitative PCR data and Western blot analyses revealed an up-regulation of RPL15 and a down-regulation of MAP1B in FCFs. These results suggest that RPL15 and MAP1B may be involved in the regulation of pathological processes in bovine FCOs and may help to establish a bovine gene data-base for the discrimination of FCOs from normal ovaries.

      • Immunofluorescent Study on Localization of Bordetella Pertussis Antigen in the Central Nervous System of Mice After Pertussis Vaccine Injection

        Choe, Jin,Kim, Won Il,Chun, Chong Hwee,Chung, Hee Young CATHOLIC MEDICAL CENTER 1973 Bulletin of the Clinical Research Institute Vol.1 No.1

        Travelling route of B. pertussis antigen into the central nervous system after the intravenous, intraneural and perineural. vaccine injection were examined with immuno- fluorescent antibody technique. B. pertussis antigen were detected in the central nervous system after 24 hours following the intravenous vaccine injection. But not detected until 12 hours after intravenous injection. And it is evident that B. pertussis vaccine can reach to the central nervous system widely through hematogenous route by permeating the b1ood-brain barrier but not by way of peripheral nerve route. The above findings explain the possible pathogenesis of encephalitis and convulsion occurred in the pertussis vaccinated people.

      • Gadolinium-Enhancement on Fast Spin-Echo MR Imaging : Impact on Diagnosis of Meniscal Tears and Differentiation of Acute and Chronic Ligament Tears

        Choe, Bo-Young,Shinn, Kyung-Sub,choi, Kyu-Ho,Jee, Won-Hee,Kim, Jung Man 가톨릭 의과학연구원 1997 가톨릭 의과학연구원 국제학술대회 Vol.1 No.-

        In conclusion, our present results showed that FSE pulse sequence could be acceptable in the diagnosis of meniscal tears, and additional FSGE MR imaging could enhance meniscal detectability (i. e., 3% increase in our study). Also, FSGE MR imaging could be useful in differentiating acute from chronic ligament injury.

      • Acute hemorrhagic edema of young children: Erythema multiforme-like vasculitis

        ( Hee Chul Chung ),( Sung Jay Choe ),( Solam Lee ),( Won Soo Lee ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1

        Vasculitis is characterized by two main features, including violaceous palpable purpura or petechiae, both of which are most likely to appear on the lower extremities. Erythema multiforme (EM) has target-like lesions, which appear as concentric circles with different contrasts. Acute hemorrhagic edema (AHE) of young children is uncommon, but when the condition is present, it is typically underestimated as cutaneous leukocytoclastic vasculitis (LCV). AHE becomes diagnostic when both EM-like lesions and violaceous palpable purpura exist. The four-year-old patient had palpable purpura and targetoid manifestations localized on the lower extremities, and based on biopsy, the diagnosis was direct immunofluorescent staining-negative leukocytoclastic vasculitis. There was a history of upper respiratory infection and an influenza vaccination occurring three weeks before onset of the condition, suggesting that an infectious causative origin might have brought about acute hemorrhagic edema (AHE). Oral Prednisolone with a dosage of 10 mg/day was started, and the dose was tapered 2.5 mg/week. Four weeks of systemic steroids successfully controlled the lesions. Because of the targetoid palpable purpura, AHE tends to be underestimated or misdiagnosed as other diseases in pediatric patients. If the patient presents with symptoms that are not conclusively one of the two conditions, then AHE should be taken into consideration.

      • Vulvar Bowen`s disease: the importance of dermatologic diagnosis

        ( Hee Chul Chung ),( Sung Jay Choe ),( Won Soo Lee ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1

        A 62-year-old female presented a well-demarcatederythematous painful patch with mild erosion on the vulva and perineum for 3 years. Although she had been treated by antifungal and antiviral therapy for several years at local gynecologic and urologic clinics, lesions were not improved. Histopathologically, the specimen revealed full-thickness epidermal proliferation with disorder and wind-blown appearance, while the dermis remained intact. Human papilloma virus type 16 was detected on the lesion. Along with above findings, diagnosis of vulva Bowen’s disease was established, followed by total excision of the lesion. Bowen’s disease on the vulvar area, so called vulvar intraepithelial neoplasia, could occasionally show atypical presentations such as erosion, ulceration and hyperpigmentation. In addition, not so much cases of vulva Bowen’s disease were reported, considering there have been only four cases of female genital Bowen’s disease in department of dermatology of our hospital from 2001 to 2014. However, dermatologists should pay more attention to the genital skin disease such as vulva Bowen’s disease than other physcians. Therefore, we recommend that the biopsy should be taken into consideration when atypical genital lesions were encountered, because many cases of vulvar Bowen’s disease would be undiscovered unexpectedly.

        Maize with Multiple Ears and and Tillers(MET) IV. Leaf Characteristics of IK Type Maize with Tillers

        Choe, Bong-Ho,Lee, Hee-Bong,Lee, Won-Koo,Kang, Kwon-Kyu,Choi, Chang-Yeol The Korean Society of Crop Science 1989 Korean journal of crop science Vol.34 No.4

        분얼하는 옥수수 교잡종 (IK//1R1/B68)의 잎이 분얼하지 않는 옥수수(진주옥)의 잎과 길이나, 폭 또는 면적에 있어서 차이가 있는지의 여부를 알기위해 주경 또는 분얼경의 지엽으로 부터 아래로 9개 잎을 수확기에 취하여 엽장, 엽폭, 엽면적을 측정하였다. 1. 개체당 주경의 평균 엽장은 IK형 (IK//IRI/B68)이나 진주옥이 거의 같았으나 평균 엽폭은 IK형이 진주옥보다 약 2cm 좁았다. 평균 엽면적 역시 IK형이 적었는데 그 이유는 엽폭이 좁았기 때문이었다. 2. IK형 옥수수에서 주경과 분엽경간의 잎특성(장, 폭. 면적)은 서로 비슷하였다. 3. IK형 옥수수는 착수절 바로 아래 절의 잎이 가장 길었고 착수절 바로 위의 잎이 가장 넓었다. 4. IK형 옥수수 잎의 절입별 병이계수를 비교한 결과 착수절을 포함한 착수절 근처 잎이 변이계수가 가장 낮았고, 착수절에서 멀리 떨어진 잎일수록 변이계수의 값이 컸다. 특히 정엽의 변이계수는 다른 잎들보다 훨씬 컸다. 이같은 경향은 주경과 분얼경의 잎이 모두 같았다. 5. 기존의 공식(장$\times$폭$\times$0.75)에 의해 추정한 엽면적보다는 직접 측정한 엽면적이 컸다. 따라서 IK형 옥수수의 엽장과 엽폭에 의한 엽면적 추정은 기존의 0.75 대신에 0.80을 이용하는 것이 보다 타당할 것으로 생각된다. Leaf characteristics of main stem and tiller of IK type maize (IK/ /IRI/B68) were compared with those of Jinjoo Ok hybrid which are not usually tillered. A total of nine leaves from flag leaf to the third or the fourth leaf below ear-bearing node were sampled from each stem or tiller. There was no significant difference in mean leaf length between IK/ /IRI/B68 and Jinjoo Ok. But the mean leaf width of IK/ /IRI/ B68 was about 2 cm narrower than that of Jinjoo Ok. The mean leaf area of the IK/ /IRI/B68 was also smaller than that of Jinjoo Ok due to the narrower leaf width. There were not significant differences in mean leaf characteristics between main stem and tillers of IK/IRI/B68. The longest leaf was the leaf below the ear-bearing node and the widest leaf was the leaf just above the ear-bearing node. Mean length. width and area of leaf on main stem and tillers were similar. Coefficients of variation calculated for individual leaf indicated that the leaves near the ear-bearing node were more uniform than others. The leaf area measured was significantly greater than that estimated by formular, length x width x 0.75. New constant to estimate leaf area of tillering maize was derived as 0.8.

Materials used were mostly from Korean local lines and a few lines from other countries were also included for comparison. The time of the first tiller development was about 18 to 20 days after emergence when planted on May in Yusong. The second tiller appeared about 4 to 5 days after the first tiller appeared. The tiller number per plant varied with lines and hybrids and ranged from two to ten. The location of tiller development was usually basal nodes of the main stem. Each tiller appeared to have its own root system. The angle between tillers and main stem was variable depending upon the maizes and the tiller angle could be classified into three categories. The height of tillers was also variable and seemed to be under genetic control. The most productive tillers were found among the Korean local derivatives.
