N/A mg/dl) in men and women was 36.8 and 44.0%, respectively and that of high LDL-cholesterol(≥160 mg/dl) was 26.6% in men and 35.2% in women. Their frequencies were increased with age in both sexes. 4) There were no significant, differences in the mean values of total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol and atherogenic index by residency. The frequency of high total cholesterol(≥200mg/dl) in Taegu and its rural area was 40.7% and 35.5%, respectively. Conclusion: These findings suggest that the mean concentrations of total cholesterol, triglyceride and LDL-cholesterol in men and women vary with age. The frequency of hypercholesterolemia (≥200 mg/dl) in men and women was about 40%, and increased with age. Values of HDL-cholesterol were not affected by age and sex

Malrotation of rnidgut occurs when the normal rotational process and fixation of intestine fail to take p]ace. The second stage during which midgut loop starts returning to abdomen from urnbilical cord is the rnost frequent period of intestinal malrotation. Malrotation is the most common anomaly in this group. Non-descent of cecum, in which this structure remains in the subhepatic position is the best known example. Most symptomatic anomalies of intestinal malrotation are found in the neonatal period and many remain asymptomatic and are incidentally found either during laparotomy or investigation of unrelated symptoms in adult life. We report a case of intestinal malrotation who has been relatively asymptomatic during his life. His presenting left lower abdominal pain and constipation is far from typical symptoms of intestinal malrotation. Only conservative treatment is needed to relieve his symptoms.

N/A The number of persons with HIV infection in Korea have increased steadily, total number of HIV infection in Korea were 478 on August, 1995. To investigate the clinicoimmunologic manifestation of AIDS in Korea, we reviewed complete blood counts (CBC), CD4 counts, serum β2-microglobulin level, opportunistic infections and cause of death for 19 AIDS patients who had been admitted or visited at Pusan national university hospital during the period of January, 1990 to August, 1995. 1) The predominant mode of HIV transmission was heterosexual contact(18), other modes of transmission were homosexual contact(1). Clues of diagnosis of HIV infection were routine occupational health examination(14), and opportunistic infection symptoms such as fever, coughing(4). 2) Mean CD4 cell counts(/mm3) were 53±72 totally, 22±27 for 8 dead patients at mean 2 month before, 91±87 for 7 living patients. There were not significant difference(p>0.05). 3) Serum β2-microglobulin(MG;ug/ml) was measured at 12 patients, mean serum β2-MG level was4.8±7.3 totally, 7.1±10.3 for 6 dead patients at mean 1.3 month before, 2.5±0.4 for 6 living patients. There were not significant(p>0.05). 4) At CBC examination, WBC(/mm3) was 5,932±2,899 totally, 5,452±3,436 for 10 dead patients, 6,500 ±2,221 for 9 living patients(p>0.05). Hb(g/dl) was 11,4±2.8 totally, 9.4±1.8 for dead patients, 13.6±1.8 for living patients(p<0.05). Lymphocyte count(/mm) was 1,255±800 totally, 731±424 for dead patients, 1,838716 for living patients(p<0.05). ESR(mm/h) was 72±47 totally, 97±33 for dead patients, 47±47 for living patients(p<0.05). 5) Opportunistic infections had developed at 14 patients, candidiasis 7, pneumocystis carinii pneumonia 5, tuberculosis 3, cytomegalovirus infection 2, herpes zoster 3, toxoplasmosis 1, cryptococcal infection 2, bacterial pneumonia 5, and herpes simplex l. Malignant lymphoma had developed in 1 patient. 6) Mean survival interval from diagnosis of HIV infection to death was 32.8±19.1 months, and the most common cause of death was pneumocystis carinii pneumonia, and other causes of death were meningitis, bacterial pneumonia and AIDS-wasting syndrome. Based on these results, We concluded that CD4 counts, serum β2-microglobulin level, Hb, total lymphocyte count and ESR in AIDS patients are specific laboratory markers of progression and prognosis of AIDS, the most common opportunistic infection was candidiasis, and the most common cause of death in AIDS patients was pneumocystis carinii pneumonia.
금속으로 피복된 tungsten 의 열이온 방출에 관한 연구
조봉기 대한금속재료학회(대한금속학회) 1974 대한금속·재료학회지 Vol.12 No.3
Eyring의 절대반응속도론을 토대로 하여 금속으로 피복된 Tungsten으로부터 방출되는 열전자류를 계산하는 식을 유도하였다. 본 연구에서 얻은 식을 Zr-W, La-W, Ce-W, Sr-W, Cs-W, Ba-W에 적용하였던 바 실험치와 잘 맞는 결과를 얻었다. Equation for thermionic emission of metal-coated tungsten has been derived from Eyring's absolute reaction rate theory, which can be used to evaluate the electron currant. The values of the electron currents for the systems, Zr-W, La-W, Ce-W, Sr-W, Cs-W and Ba-W were computed and found to he in good. agreement with the experimental results.

The double pylorus is a rare condition consisting of a double communication between gastric antrum and duodenal bulb. Some investigators postulate that the doubling of the pyloric channel is a congenital phenornenon, but others believe that it is an acquired lesion. A 72 year-old-man was admitted to this hospital because of epigastric pain for 1 month. Upper G-I series revealed thickened rnucosal folds of pylorus and duodenal bulb and dilated, deformed duodenal bulb filled with barium materials. Endoscopic findings also showed two ovoid large openings of the pyloric channel divided by smooth thickened septum and multiple gastroduodenal ulcers. We thought that this case was an acquired lesion. The relevant literatures on the subject were reviewed.
헤파린 부착 JO 스텐트와 미부착 JO 스텐트 삽입술 후의 장기 추적 성적 비교

The risk of acute or subacute closure after angioplasty has been minimized by using stent deployment. However, restenosis rating 20% ∼30% after stenting is still most important limiting factor for stenting. We investigated a long-term effect of implantation of a heparin-coated JO stent compared with the use of un-coated JO steno. Thirty eight patients were assigned heparin-coated JO stent{21 patients, JO(H)} or uncoated JO stent(17 patients, JO). All clinical and angiographic parameters were retrogradely reviewed. They were followed up monthly and performed follow-up coronary angiography 7 months later. The clinical and angiographic parameters were statistically not different between two groups, except hypertension {JO:18%, JO(H):52%, p<0.05}. The reference diameter was 3.12±0.53mm in 10 and 2.85 ±0.43mm in JO(H) (p=0.071). The minimum luminal diameter after stenting was not significantly different{2.91±0.52mm in JO, 2.78±0.42mm in JO(H), p=0.381}. The restenosis rate of JO was 32% and JO(H), 35%(p=0.545). Over seven months follow up, it seems that a strategy of elective stenting with heparin-coated JO stent was not more effective than uncoated JO stent.
