The Diltiazem hydrochloride is a new calcium antagonist of which effect on angina pectoris has been reported. Authors studied the clinical effect of Diltiazem in 18 cases of angina pectoris including stable and unstable angina. The 14 cases were male and 4 cases were female with ages ranging 46 to 72 years. All cases had typical anginal attack on 1-6 times in everyday with transient improvement by sublingual nitroglycerin. After coutine physical and laboratory work-up, Diltiazem 30mg tablet was given 3 times a day for 3 consecutive weeks and checked the response of angical pain for first 3 times visit with 3 days interval and thereafter with one week interval. In 13 cases of 15 cases, the Diltiazem alone was medicated. There was considerable improvement of anginal attack in 13 cases of 15 cases with Diltiazem alone, namely complete subsidence of anginal attack throughout 3 weeks in 2 cases, only minimal substernal discomfort on effort once a week in 4 cases and in 7 cases the frequency and severity of anginal pain reduced to about 50% of control state. In 2 of 15 cases there were no effect on anginal pain until one week, subsequently a beta-blocker was added and the anginal attack improved considerably in both cases. In 3 cases of 18 cases, the anginal attacks were so severe and frequent that the Diltiazem with beta-blocker were given from the beginning. In one case the anginal pain disappeared completely and in two cases there were good effect. The effect of Diltiazem usually started to occurs in 3 days to one week after medication. The overall effectiveness of Diltiazem in angina pectoris was 87% with excellent effect in 40%, good effect in 27% and fair effect in 20%. In 5 cases of good response to Diltiazem, the stress exercise test by bicycle ergometer was carried out before and after one week medication with programs of 30 wt, 50 wt, 75 wt, and 100 wt loading for 4 minutes in each stage. The exercise tolerance improved about 25-50 wt, the ST depression by exercise became less by 1-2mm and the maximal heart rate increased by 4-9/min. These data showed marked improvement of exercise tolerance in angina pectoris by Dltiazem objectively. There were macular skin rash, diarrhea and mild dizziness in one case respectively which were improved without treatment. These data showed that Diltiazem was highly effective in angina pectoris except few very severe cases. In severe cases, the combined therapy of Diltiazem and beta-blocker was more effective.

From Jan. 1983 to June 1984 in Yonsei University Medical College 17 patients received curative resectivesurgery due to bronchogenic carcinoma. The following results were obtained by comparing the CT findings to theoperative and histological findings of those patients. 1. The histological types of 17 cases of bronchogeniccarcinoma were squamous cell Ca. 8 cases, adenocarcinoma 7 cases, and undifferentiated Ca. 2 cases. The both ofthe undifferentiated type were confirmed by post operative histological study. 2. The lesions showing falsepositivity of mediastinal invasion are enlarged but have well circumscribed margins and separated lymph nodes. 3.In contrast, the prediction of hilar infiltration by CT gave only 25% sensitivity, 77.8% specificity and 52.9%accuracy. 4. For the clinical staging done by CT, only 47.1% were in accordance with the surgical staging. 5.However, CT is useful in selecting the patients who need invasive staging before abandoning curative resection andin suggesting the type of invasive staging according to the location of the lesion.

The effect of Atenolol on the blood pressure were studied in 31 cases of essential hypertension and on the effect of plasma renin activity in 8 cases. There were 8 cases of male with age 49.5(42-70) and 23 cases of female with age 49(35-71) years. 27 cases of 31 cases were untreated hypertensive patients and 4 cases were refractory to hypotensive drugs of diuretics and vasodilators. The Atenolol 50mg once-daily was given to all patients orally for 3 weeks. The blood pressure, heart rate, ECG and symptoms were checked in one week interval. In 8 cases, the plasma renin activity was measured by Dainabot Kit before and after one week medication. The results were as follows: 1. In 27 cases of untreated hypertension, the control blood pressure was 182.9/11.4mmHg in average. The blood pressure decreased in average by 18.3/11mmHg in one week, 23.7/15.9mmHg in two week and 21.5/10.5mmHg in three week. The heart rate also decreased by 7.4/min. in one week, 14.9/min. in two week and 7.8/min. in three week. These data showed considerable reduction of blood pressure and heart rate with 50mg Atenolol once-daily. 2. The basal plasma renin activity after one week medication was reduced by 46% in 8 cases and this data showed considerable reduction regardless control level of basal plasma renin activity. 3. There were considerable blood pressure reduction by adding Atenolol 50mg once-daily to diuretics and vasodilator to which patient's blood pressures were refractory. 4. There was no orthostatic hypotension or serious side effect by Atenolol medication.

Neurilemmomas of the extremities are nerve sheath tumors involving peripheral nerves of the extremities. We analyzed MR images of 16 surgically proved tumors in 12 patients and compared the MR images with gross pathologic specimens in two tumors (2/16). Spin echo T1-weighted images were obtained in all the patients but T2-weighted images were obtained in six patients with a gradient echo technique. Gadolinium dimeglumine enhanced T1-weighted images were obtained in 11 patients (15/16). Signal on T1-weighted images was iso or slightly higher than that of the adjacent muscles. Signal on T2-weighted images ranged from homogeneous high to heterogeneous. After Gadolinium injection, all the 15 tumors showed enhancement. Small sized tumors were enhanced homogeneously but there was a tendency tobe enhanced heterogeneously to the central portion with peripheral rim enhancement as the size of the tumors increased. Pathologically, the enhanced portion was correlated the with solid protion was correlated the with solid portion of the tumors. Also encapsulation of the mass (12/16), suspended nerve strings (9/16) and bony erosion (1/16) were detected. MR characteristics of neurilemmoma include heterogeniety on enhanced T1 and T2 weighted images, encapsulation, and suspended nerve strings. Signal heterogeneity on enhanced T1 and T2 weignted images may be attributed to the variable cellularity, cystic changes, vascularity and focal hemorrhage of the tumors.

PURPOSE: The purpose of this study is to describe the findings of the transligamnetous type of the herniated lumbar disc (HLD) with magnetic resonance MR imaging. MATERIALS AND METHODS: We retrospectively analyzed the MR images of surgically proven 20 cases of transligamentous type of HLD from January 1, 1992 to August 20, 1992. The MR imaging was performed with 1. 0T MR unit, using sagittal spin echo (SE) and axial gradient echo (GE) techniques. RESULTS: The results were as follows;1) the interruption of black line of the posterior longitudinal ligament (PLL) was identified in 19 levels and 17 levels in sagittal SE and axial GE images, retrospectively;2) the widening of adjacent epidural fat space was demonstrated in 16 cases of central or posterolateral HLD. The herniated disc material, as compared with the parent intervertebral disc, showed intermediate signal intensity (SI) in 19 and low SI in 1 level on T1WI, high SI in 10, intermediate SI in 7, low SI in levels on T2WI, and high SI in 10, intermediate SI in 9, low SI in 1 level on GE images. CONCLUSION: The most important sign of the transligamentous type HLD on MRI was the interruption of the black line with additional finding of the widening of adjacent epidural fat space. The MR signal intensity of the herniated disc was variable. Axial GE image was valuable for the evaluation of the direction of HLD and it relationship with neural structure, but had no addiational information for the degree and biochemical change of HLD over SE image.

OBJECTIVE: In order to confirm the local production of total and specific IgE antibodies in the nasal polyp tissues. MATERIAL AND METHOD: We measured total IgE and house dust mite(Dermatophagoides pteronpssinus .' DP)-specific IgE antibody using enzyme-linked immunosorbent assay(ELISA) in the supernatant of nasal polyp homogenates from 72 subjects undergoing nasal polypectomy. The subjects were divided into three groups according to skin reactivity to DP: 20 strongly atopic subjects to group I(mean wheal diameter) 3mm), 19 weakly atopic subjects to group II (mean wheal diameter 1-3mm) and 33 negative skin responders to group III. RESULT: Group I showed significantly higher levels of total and DP-specific IgE levels in the nasa
