Type-C retrovirus, human T-cell leukemia virus type-l(HTLV-1), has been shown to be associated etiologically with adult T-cell leukemia, which is an endemic disease in southwestern parts of Japan. We examined the seroepidemiological characteristics of antibody to adult T-cell leukemia virus associated antigen (anti-ATLA-antibody) by the indirect immunofluorescent assay and ELISA from the healthy individuals and various diseased patients in the Republic of Korea, a country adjacent to Japan in which HTLV-1 is endemic. The results were as follows. 24 out of 9,603 individuals(0.25%) were seropiositive. The positve rate was 0.17% in males and 0.36% in females, the sex difference was female predominent relatively. HTLV-1 carriers were found 16 individuals in Seoul, 5 in Kyonggi area, 1 in Chungnam and Jonbuk, respectively, but found only 1 individual in Busan city and Jaejoo area close to southwestern parts of Japan. Positive rate to anti-ATLA-antibody seemed to be high in older age, especially at the 50s(0. 4Yo). In conclusion the prevalence rate of anti-ATLA- antibody seemed to be very low in the Republic of Korea adjacent to Japan in which HTLV-1 is endemic and no patient with adult T-cell leukemia has been found as yet. Also we noted that the Republic of Korea is not an endemic area to HTLV-1.

We report a 28-year old female patient with pleural paragonimiasis who did not have the usual diagnostic triad for this parasitic disease. She did not have chronic hemoptysis, there were no pulmonary infiltrations, and stool, sputum and pleural fluid examinations did not yield paragonimus ova. The diagnosis was made on the basis of ova found in the pleural biopsy. Paragonimus pleural effusion was resolved with frequent thoracentesis and oral praziquantel therapy.

본 연구는 홀스타인 송아지에 대한 세 종류의 조사료가 유선조직, 반추위 유두, 번식성적 및 성장률에 미치는 영향을 조사하기 위하여 실시하였다. 출생 후 4일된 송아지(42.9±0.9㎏) 24두를 무작위로 선발하여 출생 후 4∼44일까지 전유를 급여하다가 45일에 그룹 1은 볏짚, 그룹 2는 오차드 그래스, 그룹 3은 알괄파를 급여하였다. 또한 유선조직과 반추위의 발달을 측정하기 위하여 3, 9, 18개월령에 도달하였을 때 각 처리구의 송아지를 1마리씩 도살하였다. 알팔파를 급여한 그룹 3은 다른 처리구에 비하여 중체율이 높았으며, 그룹 2는 영양소 이용률과 번식성적이 높은 경향을 나타내었다. 반추위의 무게는 3개월령 도달시에는 그룹 3이 가장 무거웠으나, 9개월과 18개월령 도달시에는 그룹 2에서 가장 무거운 것으로 나타났다. 반추위의 유두 수는 유두의 성장과 함께 일반적으로 감소하는 경향을 나타내어 유두의 길이와 유두 수와는 서로 상대적인 관계를 나타내었다. 유선의 기능적 활성을 나타내는 RNA/DNA 함량은 3개월 시에는 그룹 3이 가장 낮은 경향을 보였으나 9, 18개월 시에는 반대로 가장 높은 경향으로 나타났으며, 유선세포의 크기를 나타내는 protein/DNA 함량은 18개월 시에 그룹 2가 가장 높은 경향을 보였다. 결론적으로 본 연구에서 볏짚은 반추위의 초기 발달을 촉진하고 알팔파와 오차드그래스는 성장과 번식성적을 증가시키며 또한 초기에 유선의 발달을 촉진시키는 것으로 나타났다. Twenty-four Holstein calves were used to evaluate the effects of three different forages on growth and reproductive performances, and ruminal papillary and mammary developments. Four-day-old Holstein calves weighing 42.9±0.9 ㎏ were randomly assigned to three forage groups of rice straw (group 1), orchard grass hay (group 2), and alfalfa (group 3). All calves received whole milk from day 4 through day 44. At 45 days of age, the animals were assigned at random to one of the three dietary treatments. When calves reached the ages of 3, 9, and 18 months, one calf in each group was sacrifced for evaluation of ruminal and mammary tissue developments. Calves of group 3 gained more body weight than those of other groups, while group 2 showed an effective nutrient utilization and reproduction performance. At 3 months, the stomach weight of group 3 was the highest, however, group 2 provided the highest stomach weight at 9 and 18 months. A remarkable reduction in papillae number was observed in the rumens of all 3- to 9-month-old heifers. A decrease in number of these papillae was observed in all groups exhibiting papillary growth. There was a reciprocal relationship between the number and the length of ruminal papillae. Among the 3-month-old calves, the functional activity (RNAI DNA contents) of the mammary glands of group 3 was lower than those of other groups, whereas the trend was opposite for 9- and 18-month-old heifers. The size of mammary cell (protein / DNA contents) was the greatest for group 2 at 18 months of age. The results suggest that rice straw stimulated earlier development of rumen. Alfalfa and orchard grass improved the growth, reproduction performance, and earlier development of mammary glands.

The lung is the most common site of metastasis of extrapulmonary malignant tumor. According to past reports, metastatic cancer of the lung has been found in about 2% of all patients at autopsy. But these days, a diagnosis of endobronchial metastatic cancer utilizing bronchoscopy only is not easy. Thus we need other means of gathering more informaction, such as past history, discovery of other metastatic sites, and pathologic findings with special staining and electronmicroscope, especially in cases of poorly differentiated adenocarcinoma and epidermoid cancer, which are common types of primary lung cancer. We present 5 cases of endobronchial metastatic cancer. We found endobronchial metastatic cancer 2 cases of cervix cancer (epidermoid, adenocarcinoma), 1 case of colon cancer (adenocarcinoma), hypernephroma (renal cell carcinoma), and bladder cancer (transitional cell carcinoma). Since it was impossiole to diagnose the metastatic adenocarcinoma from the cervix only with lightmicroscopic findings, we could use past history and unusual radiologic and bronchoscopic findings which was thought to be the specific endoscopic finding of metastic endobronchial cancer. The interval between the diagnosis of the primary cancer and endobronchial metastatic cancer was 25.7 months. In the future, development of immunohistochemistry, monoclonal antibody, and molecular biologic techniques will give us diagnostic clue for differential diagnosis of metastatic endobronchial cancer from primary bronchogenic lung cancer.

In order to assess the efficacy of sublingual nifedipine in the acute treatment of moderate to severe hypertension, a single blind test was done in 30 patients, 10 males and 20 females, aged 40 to 76 years, with moderate to severe hypertension. The patients with mean sitting blood pressure(BP) of more than J40 mmHg received sublingual placebo, and BP and pulse rate(PR) were measured in sitting position 10,20 and 30 minutes after the sublingual placebo was given. The patients with post-placebo 30 minutes sitting mean BP of less than 13pmmHg were excluded from the study. The placebo treatment period was followed by the administration of 10mg of sublingual nifedipine, and BP and PR were measured 10,20,30 and 45 minutes after nifedipine was given. BP decreased with placebo treatment(p$lt;0. 01 by paired t-test, preplacebo vs. post-placebo 30 minutes). With sublingual nifedipine BP started to fall in 10 minutes and reached the lowest levels in 30 or 45 minu1es. The systolic BP decreased from 198.0±21.4mmHg to 159±20.4mmHg, diastolic BP from 122.5±13.0 mmHg to 103.2±14.4 mmHg and mean from 147.7±13.4 mmHg to 121.7±14.8 mmHg 45minutes after nifedipine(p$lt;0.01 by paired t-test). The average fall in systolic BP/diastolic BP/mean BP 45 minutes after nifedipine was 39/19/26 mmHg(p$lt;0. 001, by paired t-test). The maximal fall in systolic BP correlated better with pretreatment value(r=0.42) than the maximal fall in diastolic pressure(r=0.21), PR increased from 79±12 to 87±11/minute with nifedipine(p$lt;0.001, by paired t-test). Side effects were mild facial flushing(16.7%) and palpitation (3.3%). The findings suggest that a dose of 10mg of sublingual nifedipine is a simple, effective and safe method for the acute treatment of moderate to severe hypertension and can be used as a non-injecting alternative agent for the treatment of hypertensive emergency.

We report a case of acute renal failure with severe loin pain and patchy renal vasoconstriction after exercise. An immediate postcontrast computed tomogram of this case shows multiple patchy areas of poor contrast enhancement in the cortex of the both kidneys. A 24-hours delayed scan without further injection of contrast dye shows multiple wedge-shaped contrast enhancement in the coincident areas of poor enhancement in the immediate scan. The 2 and 5 days delayed scans show that wedge-shaped contrast enhancement becomes disappeared gradually to the renal cortex, and the 8 days delayed scan shows complete disappearance of contrast enhancement. The renal scintigrams with technetium-99m-methylene diphosphonate and dimercaptosuccinic acid show diffuse increased uptakes and multiple patchy photon deficient areas in the both kidneys respectively. The follow-up renal scintigrams show nearly normal findings, This patient had an uneventful hospital course and recovered completely without dialysis.

본 연구의 목적은 효모 세포벽, 또는 효모의 세포벽으로부터 본 연구에서 확립한 방법으로 분리한 mannoprotein(MP)과 glucan(Glu)을 동물에 급여하므로써 동물의 일당중체량, 일당사료섭취량과 사료:중체량의 비율, 그리고 동물이 가지고 있는 면역기능의 활성화정도를 조사하는데 있다. 산업적 측면에서 대량 추출하기 위하여 기존에 있는 방법을 개선하여 변형된 방법으로 효모세포벽제제를 분리하였다. 본 연구에서 분리된 효모세포벽제제(cell wall, mannoprotein glucan)와 시판중인 효모세포벽제제(Bio-Mos^(TM))를 0.1%로 4주령 횐쥐에 4주간 급여하였다. 일당중체량은 개선된 방법으로 분리한 glucan을 급여한 처리구에서 가장 높은 중체량을 나타냈으며, 다음으로 mannoprotein 급여구가 높았으며 cell wall과 시제품(Bio-Mos^(TM)) 급여구에서 낮은 중체량을 보였다. 일당사료섭취량에 있어서 glucan 급여구가 cell wall과 시제품 급여구들과 비교할 때 높았으며 사료:중체량 비율 또한 glucan 급여구에서 가장 좋은 경향을 보였다. 사양 4주깨 횐쥐로부터 spleen을 채취하여 YACl 세포에 대한 natural killer cell의 cytotoxicity를 분석한 결과 본 실험실에서 분리한 mannoprotein과 glucan이 면역 증진효과가 큰것으로 보였다. Mannoprotein 급여구와 glucan 급여구에서 대조구와 cell wall 급여구보다 면역 효과가 뚜렷하게 나타났으며(MP, P<0.01; Glu, P<0.05), mannoprotein 급여구가 glucan 급여구보다 natural killer cell의 활성도가 높았다(P<0.01). 결론적으로 효모세포벽, mannoprotein과 glucan을 횐쥐에 급여했을 때 성장능력에 있어서 유의성 있는 효과가 나타나지 않았지만 세포배양수준에서 spleen natural killer cell의 activity를 증가시키는 효과가 있다. The purpose of this study was to investigate the average daily gam, average daily feed intake, feed gain ratio and immune system activation of rats when feeding yeast cell wall, mannoprotein (MP) and glucan (Glu) which were isolated from yeast cell wall. In order to isolate the yeast cell wall products in large scale, we used the improved isolation method basing on the typical one. In this study, yeast cell wall products (cell wall, mannoprotein, glucan) and commercial product (Bio-Mos^(TM)) were fed to 4-week old rats by 0.l% during 4 weeks experimental period. Glucan(extracted from improved method) provided the highest average daily gain. Mannoprotein treated group showed the second highest average daily gain. Cell wall and Bia-Mos^(TM) fed groups showed lower average daily gain. Treatment fed glucan also showed higher average daily feed intake than that of cell wall and commercial Bio-Mos^(TM) groups. And in feed: gain ratio, glucan fed rats showed the respectively good results. At the 4th week of feeding trial, rats' spleens were obtained from all the treatments to evaluate the cytotoxicity of natural killer cell against YACl tumor cell. The results indicated that mannoprotein and glucan had the significant effects on activating immune system. Rats of mannoprotein and glucan treated groups showed the higher immune activity than that of cell wall and control groups (MP, P<0.01; Glu, P<0.05), and natural killer cell activity of mannoprotein fed rats was higher than that of glucan fed rats (P<0.01). In conclusion, although the addition of yeast cell wall, mannoprotein and glucan to the diet of rats did not provide the significant effects on growth performance, it was clear that the mannoprotein and glucan isolated in this study could stimulate the activity of spleen natural killer cell in the cell culture.

Phenochromocytoma is a catecholamine-secreting tumor, most of which grow at the adrenal gland. About 109p Of pheochromocytomas are detected at the extra-adrenal chromaffine tissues and are called paraganglioma. The main symptoms of pheochromacytoma include hypertension, headache, palpitation, and sweating. Gastrointestinal symptoms such as abdominal pain, constipation, and vomiting are found in 20∼40% of patients with pheochromocytoma, but these are usually overlooked because of the severe, prominant cardiovascular symptoms. Intestinal pseudo-obstruction without hypertension in pheochromocytoma is very rarely found. It is caused by the decreased motility of the intestine and the over-contraction of the intestinal sphincter, which are caused by the unbalanced activation of α-and β-adrenal receptors. It can be hypothesized that catecholamine receptors in the cardiovascular system are down-regulated or desensitized, but those in the intestine remain intact. We report herein a case of pheochromocytoma in which intestinal pseudo-obstruction was the main presenting clinical manifestation. Symptoms of intestinal pseudo-obstruction were completely relieved by administration of phenoxybenzamine, an α-receptor blocker, and excisional surgery.

Leukemia is known to be an extremely rare cause of diabetes insipidus. We report a case of diabetes insipidus as a complication of leukemia. An 18 year-old man was admitted because of polyuria polydipsia and fever. Bone marrow aspiration and biopsy revealed the diagnosis of acute erythroleukemia (AML, M6). On the water deprivation test, the diabetes insipidus was confirmed to be of the central type. He was managed with intranasal vasopressin for diabetes insipidus with good response. Induction chemotherapy was administered without response, and the patient died of septicemia and respiratory failure 2 months after initial diagnosis. A short review of the literature related to this subject is also presented.
