N/A Background: Magnetocardiogram (MCG), which records the changes of magnetic fields generated by the heart`s electrical activity, theoritically can provide unique data for clinical application. To date, MCG has been investigated only at a single time point after myocardial infarction (MI) with severe left ventricular dysfunction in rats. The purpose of the present study was to investigate sequential changes of MCG after MI and to evaluate effects of infarct size on MCG. Methods: Acute MI were induced by the permanent ligation of left coronary artery in 22 rats. Magnetic fields were recorded just above a rat with Nb Superconducting Quantum Interference Device (SQUID) gradiometer inside a magnetically shielded room. MCG was measured before and immediately after surgery and it was subsequently recorded at the time points of 1, 4 and 6 hours post operatively. MCG was also measured at 1, 3, 7 and 21 days after surgery. Results: Elevation of ST segment and appearance of pathological Q wave on the MCG were evident immediately after the ligation of coronary artery and persisted to 6 hours after MI. On MCG, ST segment was depressed and T wave was inverted from 1 day after MI. In rats with small-and moderate- sized MI (infarct size〈30%), ST depression returned to near the isoelectric level and Q wave disappeared from 7 days after MI. However, ST depression and Q wave were still present in rats with larger infarct (infarct size≥30%). Conclusion: Evolutional changes of MCG were well-recognized up to 21 days after MI. Furthermore, the infarct size can be expressed by the extent of Q wave and ST segment depression on MCG. Taken together, these data indicate that MCG is a helpful modality for the diagnosis, evaluation of infarct size and follow up after MI.(Korean J Med 62:42-48, 2002)

본 논문의 목적은 대학생의 인터넷 중독에 영향을 주는 요인에 대한 분석을 통해 대학생의 정신건강을 위한 공적프로그램 도입에 대한 함의를 제공하는 것이다. 분석자료는 을지대학교 강남 을지 병원 중독연구소에서 대학생 453명을 대상으로한 설문지이다. 설문조사에 사용된 설문지는 인터넷 중독을 측정하는 인터넷 중독 척도(Young척도), 불안을 측정하는 불안척도(STAI)와 우울을 측정하는 Beck의 우울척도(BDI)로 구성되었다. 분석결과 첫째, 연령 및 학년은 인터넷 중독에 유의미한 영향을 미쳤다. 둘째, 나이가 어릴수록, 학년이 낮을수록 불안과 우울에 빠지기 쉬웠다. 셋째, 무엇보다 불안이 대학생의 인터넷 중독에 가장 큰 영향을 미치는 요인이었다. The purpose of this research to suggest implications on introduction of public-program for college students` mental health through analysing the factors which impact on internet addiction of college students. The analysing data is questionnaire intended to 453 college students in Kang- Nam Eulji hospital addiction institute. The questionnaire consisted of internet addiction scale (Young-scale), anxiety scale (STAI) and depression scale (BDI). This study reveals three main findings. Firstly, age and grade have an effect on internet addiction. Second, the younger, the lower grade, they are likely to be depressed and anxiety. Third, most of all, the anxiety has the most effect on internet addiction of college students.

바나듐과 크롬의 쿠페론 착물의 전기화학적 행동을 아세트산 완충용액(pH 5.0)과 붕산염 완충용액(pH 9.5)에서 조사해 본 결과 크롬-쿠페론 착물의 환원봉우리전위(E_(ct)^(p))가 쿠페론의 봉우리전위(E₁^(p))보다 작다 (E_(ct)^(P) < E₁^(P)). 붕산염 완충용액에서 크롬-쿠페론계의 전도된 봉우리가 크게 나타나는 것은 E_(ct)^(P)와 E₁^(P)의 차이가 큰 때문인 것으로 생각된다 (ΔE = 0.40V). When the peak potentials of V-cupferron and Cr-cupferron complex compare at both buffer solution(pH 5.0 and pH 9.5), the peak potential of Cr-cupferron(E_(ct)^(P)) is smaller the peak potential of cupferron (E₁^(P)) at both buffer solution (E_(ct)^(p)) < E₁^(p)). The appearance of larger inverted peak of Cr-cupferron in borate buffer solution results from large difference of E_(ct)^(p) and E₁^(p) (ΔE=0.40 V).

In this study, physiological responses and subjective sensations were investigated depending on various high school girls' lower cloth uniform in winter. Four healthy young women were selected, and they wore same underwear and jacket. The types of lower cloth were tight skirt+stocking, flared skirt+stocking, tight skirt+legings+socks, flared skirt+legings+socks, and slacks+socks. The results were as follows: 1) The effect of the type of lower cloth in winter on the skin temperature, humidity inside clothing and subjective sensations were significant. 2) It is desirable for high school girls to wear slacks in winter, Since physiological responses and subjective sensations of slacks are superior to those of skirts. 3) It is desirable for high school girls to wear flared skirt, legings, socks in winter, Since insulation and subjective sensations of flared skirts are superior to those of tight skirts.

Semantic dementia (SD) is a temporal variant of frontotemporal lobar degeneration (FTLD). Clinical manifestation depends on which hemisphere is predominantly involved Left side predominant group presents with naming difficulty and decreased auditory comprehension of words, whereas the right side predominant group presents with prosopagnosia. We report a 61-year-old right-handed woman presented with a 6-month history of impaired ability to recognize familiar faces of her acquaintances she used to know well She scored 25/30 on Mini-Mental State Examination. Neuropsychological tests showed impairments in visuospatial, memory, and naming function When presented with photographs of 25 famous people in Korea such as politicians, sports star, actors or actress, the patient could not tell their name at all and identify occupation only 7 of 25 people. But 6age/education matched controls showed correct responses of names in 12.3±4.1 and occupation in 20.8±3.2 of 25 people. Her brain MRI showed atrophy in both anterior temporal areas, more marked on the right side. We consider this patient as the first case of right side dominant SD reported in Korea
바나듐-쿠페론 착물의 전기 화학적 행동에 미치는 산화제의 영향

쿠페론(Cupferron) 존재 하에서의 바나듐의 전기화학적 행동은 cupferron 1.0×10^(-4)M이 포함된 0.1M 아세트산 완충용액(pH 5.0)에서 순환전압 전류법으로 조사하였다. 이 조건에서 바나듐-쿠페론의 환원 반응은 (E_(p) = -0.76V) 확산 지배형 비가역반응으로 주사속도를 느리게 할 때 역주사에서 약한 전도된 봉우리가 나타난다. 이는 촉매현상의 표시가 된다. 바나듐-쿠페론 착물을 -0.40V에서 60초 동안 흡착 축적시키면 전류가 6배 정도 증가하므로 흡착과 촉매의 이중효과로 정량의 예민도를 높일 수 있다. 촉매효과를 증가시키기 위하여 보조 산화제로 브롬산 소듐을 가하였을 때 -0.10V 근처의 전도된 봉우리가 커지고 주 봉우리 (-0.75V)가 커지나 검출한계는 두 경우 비슷하다. 브롬산 소듐을 넣지 않았을 때와 넣었을 때의 검출한계는 각각 8.1×10^(-11)M, 7.1×10^(-11)M이다. Cyclic voltammetry is used for elucidating the electrochemical behavior of Vanadium-Cupferron complex in 0.1 M acetate buffer solution (pH 5.0) containing 1.0×10^(-4) M cupferron. The reduction of this complex (E_(p) = -0.76 V) is irreversible and diffusion controlled and scanning in the reverse direction produces a weak cathodic peak at slow scan rate, which is indicative of a cathodic process. When a 60 sec accumulation precedes the potential scan, a significantly (6 fold) larger cathodic peak is observed. Therefore, the dual amplification of adsorptive-catalytic effect offers higher sensitivity. By adding sodium bromate(oxidizing agent), the inverted peak current around -0.10 V in the reverse scan increase and main peak (-0.76 V) increases also a little, but the detection limit of both case is similar (8.1×10^(-11)M, 7.1×10^(-11)M)

Allylthio group of the sulfur compounds of garlic oil plays an important role for prevention and treatment of hepatic diseases to be introduced by toxic substances or carbon tetrachloride. Thus allylthio group as a pharmacologically active group was introduced into pyridazine nucleus and a substituent such as halogen or alkoxy was also introduced into the para-posi-tion of allylthio group. Three allylthiopyridazine derivatives were synthesized and their hepatoprotective activities were screened in rat. Under the three compounds (6, 7, 8), 7 and 8 (methoxy-, ethoxy-substituent) are hepatoprotective, but 6 (chloro-substitu-ent) is negative.
