박경식,이승현,최석영,박태규,이동화,이찬우,정성복,이인규 啓明大學校 醫科大學 1997 계명의대학술지 Vol.16 No.3

부신피질 자극호르몬 단독결핍은 국내에서 7례만이 보고된 희귀 질환이며 병인 및 경과 등 아직 불분명한 측면이 많다. 이는 질환지체의 희귀성도 있지만 치료후 자연경과에 대한 장기적인 추적검사가 이루어진 경우가 드물기 때문이기도 하다. 저자들은 비특이적인 전신증상을 주소로 내원한 폐경기후의 56세 여자 환자에서 자가면역질환의 증거없이 고프로릭틴혈증을 보인 부신피질 자극호르몬 단독결핍 1례를 경험하고 1년간의 부신피질호르몬 대치요법후 추적검사를 실시하였기에 문헌 고찰과 함께 보고하는 바이다. Isolated ACTH deficiency is a rare disorder which shows secondary adrenal insufficiency with normal states of other pituitary hormones. A 56-year-old postmenopausal woman complaining general weakness and intermittent mental confusion presented negligible serum cortisol and ACTH level with hyperprolactinemia and mild hyponatremia. Rapid ACTH stimulation test did not show significant increase of serum cortisol level. Combined pituitary stimulation test showed negligible response of cortisol and ACTH, and slightly decreased response of prolactin and gonadotropin. But the responses of TSH and GH were normal. There was no evidence of organic pituitary of hypothalamic lesion in brain MRI and antithyroid autoantibody was not detected in serum. After receiving 12 months of glucocorticoid replacement therapy, she skipped the medicine for 3 weeks and we performed follow-up endocrinologic tests. Serum ACTH and cortisol level was also negligible and prolonged ACTH simulation test showed normal response of serum cortisol. CRF stimulation test showed no response of serum ACTH. Basal prolactin level was decreased to near normal and combined pituitary stimulation test showed normal response of prolactin with slightly blunted response of TSH and GH. We concluded that the case was nonautoimmune origined isolated ACTH deficiency which was accompanied by hyperprolactinemia and resultant deficiency of gonadotropin, so we report this case with review of literatures.

이석주,최영근 경희대학교 체육과학연구소 1979 體育學論文集 Vol.7 No.-

For the purpose of finding out physical and character of rugby-football players, 50 players of highschool and 50 players of college have become the object of test standing height, body weight, 100m-running, 1500m-running, zigzag-run, kick, rugby-ball throwing through 1st, March, 1979 to 31th, March, 1979. According to the document of rugby-football association, trying-number of major goal-in of 19 years, from 1960 to 1978, and trying-number of all 228 games of spring-season-leagues and championship for list were accounted per 5 years. The physique of rugby-football players showed in average 174.0cm-standing height, 69.2kg-body weight and players of college are superior to them of highschool. Their record showed in average 13.3 seconds in 100m-running, 5 minutes and 57 seconds in 1500m-running and 10.3 seconds in zigzag-run with rugby-football. They marked 39.3m in kick, and threw rugby-football 7.7 times successfully, which show that there is no difference of highschool players and college players. But players of highschool and college marked a little superiority in test-record of 100m-running, zigzag-run, and kick. The trying-number did not change distinctively in 1960's, but, since 1970's, it has increased and trying-number of T.B. also has increased while it of F.W. decreased. The general trying-number is 258 in F.W. 57 in HB, and T.B-trying-number marked the highest record as marking the record 431.

Effect of Moisture on the Degradation of a SrAl₂O₄:Eu²⁺ Materials in a Cd-Free Optical Sensor

Choi, Hyoung-Seuk,Choi, Duck-Kyun,Choi, Soon-Mok American Scientific Publishers 2016 Journal of Nanoscience and Nanotechnology Vol.16 No.11

<P>Although cadmium sulfide (CdS) photovoltaic cells are widely used in optical sensors owing to their low cost and high reliability, there is an increasing need to develop a Cd-free sensor. Eu2+-activated strontium aluminate (SrAl2O4:Eu2+) is an important material with high efficiency in the visible region, good stability, and good chemical and thermal resistance. In the present study, a SrAl2O4:Eu2+-based optical sensor possessing the abovementioned photovoltaic characteristics was manufactured. There is a need to assess and improve its reliability even in the development stage so as to achieve a reliability either comparable to or greater than that of the CdS cell. The failure modes of both the CdS and SrAl2O4:Eu2+ systems were investigated to predict a failure mechanism in the field settings, and an optimized reliability test was designed. Based on the above, the relative life of the SrAl2O4:Eu2+ system and the commercial CdS system were compared by conducting a comparative life test. The failure mechanism was closely investigated after the comparative life test and the design of the SrAl2O4:Eu2+ system was modified to improve its reliability.</P>

Development of Competitive ELISA for Detection of Avian Metapneumovirus Antibodies in Chicken

Choi, Kang-Seuk,Kim, Jin-Won,Lee, Eun-Kyoung,Jeon, Woo-Jin,Park, Mi-Ja,Lyoo, Yeh-Na,Kwon, Jun-Hun 대한미생물학회 2010 Journal of Bacteriology and Virology Vol.40 No.3

Avian metapneumovirus (aMPV) causes an acute and highly contagious upper respiratory tract infection in turkeys and chickens. In this study, a competitive ELISA (C-ELISA) was developed for the detection of antibodies to aMPV in chicken sera and/or their egg yolks. This assay is based on the competitive binding of monoclonal antibody with serum antibodies to recombinant aMPV N protein expressed by a recombinant baculovirus. The C-ELISA showed specificity and sensitivity of 100% and 98.0%, respectively, when compared to the virus neutralization test. In specific pathogen-free chickens experimentally infected with aMPV SC1509 strain, the C-ELISA started to detect antibodies to aMPV as early as 5 days post infection from birds infected with aMPV, while a commercial ELISA kit detected first 10 days post infection. The C-ELISA was similar or superior to a commercial ELISA kit when serum and egg yolk samples collected from chickens on six outbreak farms were tested for diagnosis. The C-ELISA developed in the present work provides a short turnaround time and can be a useful diagnostic and screening tool for aMPV infection in the field.
