The multistage maximal exercise test was performed to 135 cases with various heart disease and 207 control group between jan. 1980 and Dec. 1980 in KoreaGeneral Hospital. The change of heart rate, blood pressure and ST segment in various heart disease were compared with those in control group. The results were followings; 1. There were 130 male and 77 female of cases with control group, whose mean age were 50 years old. 2. General check up was the most common underlying disease of control group(67 patients) and the others were gastritis (28), neurosis (24), diabets mellitus (17), hepatitis (4) and peptic ulcer (4) frequency. 3. Change of heart rate, blood pressure and ST segment in control group during GXT were 89~154, 119/80~157/88 mmHg and 0.6~2 mm. 4. There were 81 male and 51 female of cases with various heart disease group, whose mean age were 50 years old. 5. Atherosclerotic heart disease was the most common underlying disease of various heart disease group (49 patients) and the others were hypertension (34), hypertensive cardiovascular disease (22), labile hypertension (14), angina (7), arrythmia (6) and others (3) in frequency. 6. Change of heart rate, blood pressure and ST segment in various heart disease group during GXT were 85~148, 140/93~178/102 mmHg and -0.7~1.3mm. ST segment in atherosclerotic heart disease, hypertension, hypertensive cardiovascular disease, valvular heart disease and myocardial infarction were significantly depressed(p<0.05) compared with ST segment in control group.

Although myocardial bridge is not thought to have any hemodynamic significance in most cases, some have suggested that when it produces severe systolic narrowing, ischemia or infarction may result. Myocardial bridge in adults with hypertrophic cardiomyopathy may be associated with a higher incidence of sudden death, myocardial wall-motion abnormalities, and perfusion defects on thallium-201 scintigraphy. When myocardial bridge is associated with left ventricular hypertrophy, it is known to affect longer segment and cause more severe compression during systole. We report a case of hypertrophic cardiomyopathy with myocardial bridge at the middle part of the left anterior descending coronary artery, who also showed reversible perfusion defect on the thallium scan at the same coronary territory.

Plasma col1 leukemia with motility-related morphological behavior is rarely studied. The plasma cells have variable degrees of cytoplasmic morphologies as dairy Projections, long extensions and pseudopods. These morphological evidences show the papa bility of wide spread and dissemination of disease itself. We present a case of a 38 year old woman who had back pain for 4 months and was diagnosed as a solitary plasmacytoma of the third lumbar vertebra. In spite of resection of the tumor and chemotherapy, the plasmacytoma was disseminated into both breasts and ovaries within less than a year. On her blood examination, we counted 34% of plasma cells in peripheral blood and 91.6% of plasma cells in bone marrow aspiration. Most of them resealed hairy projections and pseudopods of the cytoplasm.

OBJECTS AND METHODS: In order to evaluate the relationships between drinking habits and biological and psychosocial characteristics, the authors administrated the questionnaires about drinking patterns and acute physiological and psychological responses after drinking, several psychological scales and ethanol patch test to 94 male medical students in Chosun University. RESULTS: 1) Low consumer group had significantly more severe physiological repondents after drinking in family members than high consumer group(p<.005). 2) Low consumer had significantly more severe acute physiological responses(p<.005) and high consumer group revealed more positive psychological responses after drinking(p<.005). But there was no difference in the degree of negative psychological responses between tow groups. 3) High consumer group had significantly more extroversion tedency(p<.01) and recieved more financial support from family than low consumer group(p<.01). 4) In the results of ethanol patch test. low consumer group showed more positive skin reaction in three test occasions than high consumer grou(p<.005). 5) Also the high consumer group revealed higher scores in factor 1,2,4(alpha=0.005), and 3(alpha=0.01) in comparison of factors of Korean Alcohol Use Inventory. 6) In comparison of drinking habits, low consumer group revealed higher incidence of nearly non-drinkers and sublimatory drinkers. But there were more casulal social drinkers, selcontrolled social drinkers, impusive-binge drinkers, and habitual-excessive drinkers in high consumer group(p<.005). And in drinking patterns, the items of dependence and duration of drinking, daily drinking disposition, preferential beverage, average and maximum drinking amount of each liquor, and magnitude of sips taken were higher in high consumer group. Only one item of interval between sips was longer in low consumer group(p<.005). 7) In comparison of sociodemographic variables, there were more students who were smokers(p<.01), from larger cities and small family(p<.05), and whose parents were well educated(p<.05) but had worse marital realtionship(p<.05) in high consumer group. CONCLUSEION: For better explanation of the etiology and characteristics of alcoholism, we investigated the differences in various aspects between low alcohol consumers and high alcohol consumers in college students. The most evident differences lied in the degree of acute physiological reaction and positive rates of ethanol patch test that strongly suggested the relations with the activty of ALDH. Some differences in psychosocial aspects between two groups were noticed but could not appropriately be explained at this time.

PURPOSE: To report a case in which radiotherapy damaged the microvasculatures of the retinal vessels and developed cotton-wool patches and retinal hemorrage as well as rubeosis iridis and intractable neovascular glaucoma. METHODS: A 64-year-old female presented with visual loss in her left eye two years after radiotherapy for malignant melanoma of the nasal cavity. The visual acuity of her left eye was counting fingers. Although any specific signs were not shown in the cornea or lens, multiple cotton-wool patches and retinal hemorrhages were noted around the optic disc. RESULTS: Multiple cotton-wool patches and retinal hemorrhages disappeared gradually. Finally, rubeosis iridis and intractable neovascular glaucoma developed which could not be controlled by panretinal photocoagulation. CONCLUSIONS: Radiotherapy for malignancy of the nasal cavity was associated with intractable neovascular glaucoma.

BACKGROUND: Elevated plasma homocysteine concentrations are an independent risk factor for vascular disease. The metabolism of homocysteine is closely related to vitamin B12 and folic acid. The purpose of this study is to evaluate the correlation between homocysteine and vitamin B12 as well as folic acid in patients with coronary artery disease. METHODS: Sixteen patients, in whom coronary angiography revealed more than 50% of stenosis at least in one coronary vessel, were enrolled as the patient group, and sixteen hypertensive subjects were selected as the control group. Blood was collected in the peripheral vein to measure the concentrations of homocysteine, vitamin B12, and folate. We evaluated the correlation between homocysteine, vitamin B12 and/or folate in both groups. RESULTS: Total plasma homocysteine concentrations were higher in the coronary artery disease group than in the control group. There were no significant differences in the folate and vitamin B12 levels between the coronary artery disease group and the control group. In the control group, the concentrations of homocysteine showed negative correlation with both vitamin B12 and folate concentrations, but similar trends were not observed in the coronary artery disease group.

We analyzed the factors of importance for nonunion in series of 91 open fractures of tibial diaphysis which were treated with external fixation. Factors analyzed included, age and sex of the patients, the mechanism of injury, the amount of soft tissue damage, the grade of comminution, the level at which the tibia was fractured, the presence of an intact fibula, the presence of the multiple injuries, the type of the external fixation used(AO external fixator, EXTOR; monotube external fixator, Ilizarov), and the need to supplement the stability of the reduction. We found that the amount of soft tissue damage and comminution of the fracture played a role in the development of the nonunion.
