The antiarrhythmic effect of oral amiodarone was evaluated by 24-hr Holter monitoring in 12 patients with frequent and/or complex ventricular ectopy. Amiodarone was administered as following schedule; 600mg a day for the 1st week, 400mg a day for the 2nd week and 200mg a day, 5 days a week from the 3rd week. In 9 patients, the frequency of VPC decreased significantly or the grade of VPC changed to the more benign grade, so we considered them as "Effective Group" (75%). In 7 patients, both the frequency and the grade of VPC improved, so we considered them as "Excellent Group" (58%). No significant side effect was observed during investigation. We concluded that amiodarone is very effective antiarrhythmic drug and has no serious side effect during a short-term observation.

Muchz-Habermann disease is cutaneous disease of unknown etilogy and characterized by a, polymorphous eruption consisting of papulosquamous, bemorrhagic, ulceronecrotic lesion eventually into varioliform scars. It is also classified into parapsoriasis group according to Broq with parapsoriasis en guttata (pityriasis lichenoides chronica), parapsoriasis en plaques, parapsoriasis en lichenoides. The 61-year-old male patient visited to Dermatologic Department of Severance Hospital due to sudden onset of generalized eruption. He presented pea to fingr tip sized erythematous, silvery maculo-papulo-squamous eruptions on trunk, extre- mities and buttock, but didnt complain of any subjective symptoms except markel fatigue. Skin biopsy was done on right forearm and was confirrr.ed to pityriasis lichenoides et varioliformis acuta by histopathologic finding. The lesion was completely controlled by oral tetracycline 2. Ogm per daily for first 4 wecks and reduced dosage l. Ogin per day for second 2 weeks.

Pathologic fracture occurs in a bone with preexisting stuctual weakness. The author reviewed 30 cases of pathologic fractures in which admission record and X-ray finding was well preserved among 53 cases admitted patients in the department of Orthopaedic Surgery, Seoul National Universty Hospital for 10 years from 1967. The results were as follows: 1.Age & Sex incidence showed even distribution. 2. The most frequent involved site was femur (40%) 3. The underlying etiology was as follows: 2 chronic osteomyelitis 1 homophilia 7 benign tumor 20 malignant tumor 4. metastatic tumor was the most frequent cause in 30 cases. 5.

Thirty patient with essential hypertension were administered Manidipine, a new calcium antagonist, 10~20mg once daily to evaluate the hypotensive efficacy and safety for 8 weeks. And the followings were the result. 1) Patients were consists of 14 male, 16 female, aged 53 in average and classified as mild in 21 and moderate in 9 patients. 2) Optimum intial dose was 10mg and 10 to 20mg were the doses recommended. 3) Blood pressure dropped after 8 weeks 24/13mmHg in average, rewarding 80% effectiveness and normalized in 87%. 4) Most frequent side reaction was facial flushing in 5 patiens followed by palpitation and dizziness, all of which did not disturb the continuation of medication. 5) Most of routine laboratory parameter were normal and unchanged between before and after the trial. 6) Overall rating of usefulness was 77%. In conclusion, Manidipine 10 to 20mg once daily regimen is well tolerated and effective in the treatment of mild to moderate essential hypertension.

Ambulatory BP monitoring was performed in a patients with pheochromocytoma before and after removal of the tumor. Before surgery, it did not show any significant diurnal variation. But, after surgery the diurnal variation was restored.

In order to assess the biocompatibility of domestic dynamic compression plates and screws manufactured at KAIST (Korea Advanced Institute of Science and Technclogy), hematological, serological, histological, and metallurgical studies were carried out on sixty rabbits through thirty-two weeks. The rabbits were divided into two groups, group I: thirty rabbits for KAIST plates and screws, group II: thirty rabbits for Osteo plates and screws. The plate and screws were fixed on the fixed tibial shaft. All the resulg of hematological, serological, histological, and metallurgical study revealed that there were no meaningful differences between the two groups. This, in fact, enco.urages us to use domestic KAIST plates and screws clinically and to develop more complicated designs including total joint replacement system.

To assess the prognostic value of the 14 ECG variables obtained from the pre-discharge ECG, 35 patients were followed up for at least one year among the 80 patients of the acute myocardial infarction admitted at Seoul Paik Hospital from Sep. 1983 to Aug. 1986. The following results were obtained. 1) The overall in-hospital mortality rate was 20% and the mortality rate tended to decline year by year. 2) The one-year mortality and morbidity rate of the followed patients was 31.4%. 3) Among the 14 variables obtained from the pre-discharge ECG, T-negativity was the only statistically significant (p<0.05) one to predict the one-year prognosis in the patients after the first myocardial infarction, and we could not derive any meaningful datd from the analysis of the combined effects of the three ECG variables (PTF, ST depression and ST elevation).

The antihypertensive effects and serial changes of serum lipids were observed in 17 patients with essential hypertension, administered daily 30-60mg dose of Tripamide(Tripamol(R)) for 8 weeks. The results were as follows ; 1) After 8 weeks treatment, there is no change of serum total cholesterol, serum triglyceride and HDL-cholesterol were decreased by 3.2mg/dl(-1.9%) and 0.9mg/dl(-2.8%) respectively. The changes were not significant statistically. 2) After 8 weeks treatment, mean systolic and diastolic blood pressure were decreased by 11.2mmHg(-6.8%) and 7.7mmHg(-7.3%). 3) No significant side effect was observed during treatment except of 2 patients of mild headache and insomnia.

BACKGROUND: Hypertension is a major and growing public health problem and it calls for life-long management. The antihypertensive agents are still playing major roles in the management of hypertension. We studied the effect of the long-term therapy with a new calcium channel blocker, felodipine in patients with essential hypertension. METHODS: We recruited 31 patients with mild to moderate essential hypertention and gave them 5mg (1 tablet) of felodipine(Munobal(R)) once daily for 12 months. We measured the blood pressure and the heart rate every month and tried to detect any untoward symptoms and signs during the whole observation period. Baseline work-up for the hypertensive patients were done as usual before and after the study. RESULTS: The average systolic and diastolic blood pressures were 162.7+/-9.7/99.6+/-7.4mmHg respectively before the administration and they came down to the level of 139.7+/-15.0/87.3+/-8.6mmHg respectively at the end of the 1st month (p<0.05). This trend was maintained during the whole observation period, so they were 141.2+/-11.0/85.6+/-8.2mmHg respectively at the end of the study (p<0.05). Untoward drug reactions such as gastrointestinal troubles, facial edema, leg edema, chest pain and headache were present in 11 patients (35%) but they were not serious. There was no case in which the drug was withdrawn. There was one case in which the level of the serum triglyceride increased after the administration of the drug. CONCLUSION: Felodipine has good and persistent hypotensive effect and it is safe and easy to use.
