Measurement of various portions of the corpus callosum was performed on magnetic resonance(MR) images of 114 subjects with no known or suspected corpus callosal disorders. Midsagittal T1-weighted images used for measurements and mean diameters of various portions in each age and sex group were obtained. Measures of five portions were made : (A) the anterio-posterior length, (B) the diameter of genu portion, (C) the diameter of splenium, (D) the diameter of and mid-body portion, (E) the diameter of narrow portion at the body of corpus callosum. The mean diameter in each gender group for A, B, C, D, and E were 68.8mm, 12.1mm, 12.3mm, 6.9mm, 4.1mm in male and 69.9mm, 12.0mm, 12.1mm, 6.4mm, 4.1mm in female, respectively. The groups of 0-9 years of both genders showed the minimum mean value in each portion.

PURPOSE: The purpose of this study is to evaluate the gadolinium-enhanced MR imaging findings of cerebral venous angiomas, and to compare those findings with those of cerebral angiography. MATERIALS AND METHODS: We reviewed the findings of gadolinium-enhanced MR images of 11 cases with angiographically proved cerebral venous angiomas. We obtained Tl-and T2-weighted images with gadoliniumenhanced Tl-weighted images at a 0.5 T MR imager with a spin-echo technique. We analyzed the location and signal intensity of the lesion, pattern of contrast enhancement, the distribution of draining veins and medullary veins before and after contrast enhancement, and then compared with the findings of cerebral angiography. RESULTS: The characteristic central tubular signal void structure showed low signal intensity on Tl-weighted images and high signal intensity on T2-weighted images in all cases. After gadolinium enhancement, we could find a characteristic enhancement of all medullary and central veins in 7 cases. CONCLUSION: Gadolinium-enhanced MR image was useful in the diagnosis of venous angiomas especially in the detection of medullary veins. The invasive cerebral angiography could be replaced by this technique in this disease.

BACKGROUND: Tuberculosis itself causes not only lung parenchymal destruction but also pulmonary vascular damage. Secondary emphysema also causes pulmonary vascular damage, which can develop as a late sequela of pulmonary tuberculosis. Therefore, pulmonary circulatory impairment tends to be more severe in post-tuberculosis emphysema than in primary emphysema. In post-tuberculosis emphysema, the right ventricular function may play an important role. However, little information regarding the right ventricular function is available. The purpose of this study was to evaluate and compare the right ventricular function between post-tuberculosis emphysema and primary emphysema. METHOD: Post-tuberculosis emphysema(PTE) or primary emphysema(PE) was diagnosed by history, HRCT finding and pulmonary function. Twenty patients with post-tuberculosis emphysema were matched with 20 patients with primary emphysema according to both FEV1 and FVC. Arterial blood gas analysis and echocardiography were done at rest and immediately after symptom-limited exercise. The right ventricular function was evaluated with the right ventricular ejection fraction using a modification of Simpson's method. RESULTS: There was no significant difference inthe demographics and pulmonary function between the two groups. In post-tuberculosis emphysema, the PaCO2 was higher (42.9±4.7 vs 38.8±3.1 mmHg at rest ; 47.9±7.0 vs 41.1±5.9 mmHg after exercise ; p<0.01) and the right ventricular ejection fraction was lower (57.6±6.5 vs 61.4±4.7 % at rest ; 51.1±10.8 vs 59.8±6.6 % after exercise ; p<0.01) both at rest and after exercise. The PaO2 after exercise was also lower (65.7±12.6 vs 80.2%±14.4 mmHg, p<0.01), while the PaO2 at rest tended to be lower(82.9±12.0 vs 87.8±7.5, p>0.05). In both groups, right ventricular ejection fraction correlated with the PaO2 after exercise(PTE r=0.536, PE r=0.557), and the PaCO2 at rest(PTE r=-0.576, PE r=-0.588) and after exercise(PTE r=-0.764, PE r=-0.619). CONCLUSION: Impairment of the right heart function and gas exchange were more serious in post-tuberculosis emphysema than in primary emphysema, and gas exchange may be influenced by the right ventricular function in post-tuberculosis emphysema.

BACKGROUND: Acne is a common chronic disease which most frequently affects the face. This visibility is a major cause for concern in affected individuals. OBJECTIVE: The purpose of this study was to investigate the quality of life of patients with acne. METHODS: We interviewed 130 acne patients, and determined the impact of acne on the quality of life with a questionnare. RESULTS: Among 130 cases of acne, the numbers of male and female patients were 52(40.0%) and 78(60.0%) respectively, and tbe mean age was 21 years. There was no difference between the sexes in the quality of life criteria used. The scores of social criteria of patients older than 20 years were significantly higher than thme of patients younger than 20 years. The severity of facial acne was correlated with the severity of chest acne but not with that of back acne. The severity of chest acne was correlated with that of back acne. The severity of facial acne was correlated with the scores of the physical, social and psychological criteria, and the severity of chest acne was correlated with that of physical and social criteria. However, the severity of back acne was not correlated with those of any of the criteria. The psychological well-being of the patients was moderately or highly affected by the acne more often than the other criteria. CONCLUSION: Acne has a substantial impact on the quality of life. The practical use of these indices are: (1) reveal areas of particulur concern in patients with acne; (2) to identify individuals who may require more intensive treaiment; and (3) to give a patient oriented inforrnation on the quality of life expected.

The purpose of this study was to confirm that calcium intake and healthy status play a role in reducing the risk of cardiovascular disease, to assure that calcium intake and regular exercise are important in reducing serum lipid levels in middle-aged women. Daily nutrient intakes were analyzed by convenient method. Anthropometric measurement such as body weight and height and blood pressure were measured. The subjects divided into two groups : women in group I under 50 years of age(< or = 49 yr group) and those in group II 50 years up(> or = 50 yr group). Average ages of group I and II were 43.87 and 53.46 years. The nutrients intake of subjects were higher than Korean recommended dietary allowances(KRDA) except calorie, iron, calcium, vitamin B1. They showed significant difference each other in vitamin B2(p<0.05), calcium(p<0.01) intake. Mean daily calcium intake was 540.88mg in < or = 49 yr group and 519.50mg in > or = 50 yr group. The levels of serum cholesterol, triglyceride, blood pressure, Atherogenic Index(AI), LDL/HDL and Cardiac Index(CI) were increased with age. The triglyceride and total cholesterol concentrations and LDL/HDL in > or = 50 yr group were significantly higher than those of < or = 49 yr group. There was a highly significantly positive correlation between age and triglyceride, total cholesterol and Atherogenic Index(AI). Triglyceride, total cholesterol, LDL-cholesterol concentration and Atherogenic Index(AI) were positively correlated with body weight and WHR(waist-hip ratio). Also ther was a significantly negative correlation between exercise and Cardiac Index(CI). Also a significantly negative correlation was found between Ca intake and LDL-cholesterol. Exercise and Cardiac Index(CI) also had a significantly negative relation. The results suggest that increased habitual physical activity and calcium intake should be recommended as a way of decreasing blood lipids and blood pressure in middle-aged women.

The search for tumor-avid agents for use in nuclear medicine imaging is an ongoing field of importance. The purpose of this study was to determine the affinity for radiolabeled vitamin B12 by a wide histologic variety of tumor types in mice. Seventeen different types of tumor were grown subcutaneously in female Balb/C or Balb nu/nu(nude) mice. When the tumors reached about 1 cm in diameter, mice were injected intraperitoneally with 57Co-vitamin B12. Twenty-foul hours later, the mice were sacrificed. Organs and tissues were removed, weighed, and activity per mg determined by gamma counter. Values represented cpm/mg tissue that was normalized to 20 grams body weight for each mouse. A wide variety of tumor types showed significant uptake and concentration of 57Co-vitamin B12, as evidenced by tumor:tissue activity ratios. For many tissues of great importance in terms of background(bone, muscle, blood), the tumor:tissue activity ratios of uptake were high. These data strongly suggest that further efforts to evaluate the utility of radiolabeled adducts of vitamin B12 for clinical use in oncologic imaging are warranted.

The anti-inflammatory activity of a corticosteroid may mask the contact allergic reaction it is causing. This may be an important reason why contact allergy to corticosteroids has often been missed. A simple persistent aggravation of a dermatitis in a patient treated with one or more topical corticosteroids is sufficient to raise a suspicion of corticosteroid hypersensitivity. A 23-year-old male visited our department for the evaluation of his aggravated pruritic oozing erythematous papules, scales and edema of the face. Previously, he was treated with Dermatop ointment and Plancollotion. A Patch test showed positive reactions to prednicarbate 10%, 1%, hydrocortisone-17-butyrate 10%, and triamcinolone 10%. We conclude prednicarbate in Dermatop ointment, hydrocortisone-17-butyrate in Plancol lotion to be the etiological agents.
