beta-receptor antagonist as antihypertensive agent has adverse effect such as vasoconstriction, bronchoconstriction and aggravation of atherosclerosis. So beta-receptor antagonist with alpha-receptor blocking property has been studied for avoidance of adverse effects of beta-receptor antagonist. Nipradilol, a new beta-receptor antagonist with alpha-receptor blocking property was administrated in 30 essential hypertensive patients for 10 week in order to evaluate the antihypertensive effects and adverse effects. The results were as follows: 1) Nipradilol was effective in 20 patients(67%) on systolic blood pressure 22 patients (73%) on diastolic blood pressure at the end of 10 weeks treatment. 2)Before medication, mean systolic and diastolic blood pressure in sitting position were 160+/-14mmHg and 102+/-18mmHg,and after 10 weeks of medication, mean systolic and diastolic blood pressure were significantly declined to 143+/-22mmHg and 89+/-12mmHg(p<0.001). 3) There was no significant change in pulse rate, from 78+/-12 beats per minute the beginning of the treatment to 75+/-11 beats per minute after 10 week of treatment. 4) There was no significant changes in sodium, potassium, GOT, GPT, bilirubin, alkalin ephosphatase, BUN, creatinine, LDH, CPK and lipid. 5) The adverse effects of nipradilol were bradycardia(7%), dyspnea(3%), chest discomfort(3%) and headache(3%). In summary, nipradilol seemed to be effective antihyertensive drug in treating mild to moderate hypertension.

BACKGROUND: Dopamine receptors are strong candidates for involvement in schizophrenia and are target of a wide variety of antipsychotics. Dopamine D5 receptor(DRD5) gene polymorphisms may be associated with various treatment response. The purpose of our study was define to what significance can be held as a predictor of treatment response in this polymorphism. METHOD: The total number of 116 Korean chronic schizophrenic patients was assessed after 48 weeks treatment. The Positive and Negative Syndrome Scale(PANSS) was rated for the clinical response to various antipsychotics. With the use of polymerase chain reaction amplification, we assessed this dopamine D5 receptor polymorphism in schizophrenic patients who had been treated with antipsychotics, and related genotype with treatment response, to test the hypothesis that DRD5 polymorphism may lead to varying resonse to antipsychotic. RESULT: DRD5 polymorphism was not associated with treatment response to a variety of antipsychotics in chronic schizophrenic patients. CONCLUSION: Genetic variation of D5 receptors do not predict treatment response to antispychotics.

1) Daily dose was 10-20mg Q.D. for 12 weeks. 2) Mean systolic and diastolic pressure were decreased by 49mmHg(25.9%), and 18mmHg(16.8%) respectively. But there was no significant change in heart rate before and after treatment. 3) Systolic and diastolic blood pressure were stably maintained on the whole day. 4) There were no significant side effects except two cases of aggravated congestive heart failure and hypertension. 5) There were no significant changes on hematologic & biochemical parameters before and after treatment.

A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.

A clinical review was made on 48 cases with cor pulmonale who were admitted to medical department, National Medical Center, between 1973 and 1982, and the results were as follows : 1) Teh age of subjects ranged from 26 to 88, and their mean was 51. male to female ratio was 1.6:1 and majority of them were in their 6th and 7th decade. 2) COPD was the most common cause of cor pulmonale but pulmonary tuberculosis had also a considerable portion. Less commonly it was caused by chest deformity which was mainly from spine tuberculosis and kyphoscoliosis. 3) Almost all patients were admitted with over heart failure. 4) Laboratory features showed indirect evidence of heart failure and pulmonary hypertension in chest X-ray films, RVH patterns in EKG and hypoxia and hypertcapnea with metabolic compensation in arterial gas analysis. 5) The case fatality rate was one-forth and that from kyphoscoliosis was especially high(80%).

The authors investigsted the effects of azelaic acid on human melanoma cells (G 361 melanoma cell line) and cultured normal melanocytes obtained from the prepuce of newborn. The results were as follows : 1. The proliferation of melanoma cells was decreased, but not in a dose-and time- ependent fashion. The cell population of melanoma cells after 2, 4, and 6 days of culture was decreased to 3.80 x 10(5)cells/well, 4.55 x 10(5)cells/well, and 4.30 X 10(5)cells/ well, respectively, in the presence of 10(-2)M azelaic acid. The proliferation of mormal elanocytes of normal melanocytes was decreased in a dose-dependent, but not in a time-dependent fashion. The cell population of normal melanocytes after 2, 4, and 6 days of culture was significantly decreased to 6.38 x 10(5)+/-1.37 x 10(5) cells/well, 5.33 x 10(5)+/-0.73x10(5) cells/well, and 7.20x10(5)+/-1,11 x10(5)cells/well, respectively, in the presence of 10(-2) M azelaic acid(p<0,05, p<0.01). 2. A dose-and time-dependent inhibition of DNA synthesis was not found in either group. However, DNA synthesis in melanoma cells was decreased to 92710+5188 CPM, 16268+/-15S5 CPM, 8518+/-996 CPM, respectively, after 2, 4, and 6 days of culture, and in normal melanocytes was decreased to 9398+/-2279 CPM(p>0.05) and 6953+/-1217 CPM (p<0.05) after 4 and 6 days of culture in the prensence of 10(-2) Mazelaic acid, 3. There was no difference in melanin content per well at various concentrations in either group, but the melanin content per individual melanocyte of the melanoma cells was increased to 0.0303 ng/cell, 0.0253 ng/cell, and 0.0377 ng/cell, respectively, and that of normal melanocytes was signifieantly increased to 0.0754+/-0.0215 ng/cell, 0.0719+/-0.0144 ng/cell(p<0.05), and 0.1089+/-0.0185 ng/cell(p<0.05), respectively, after 2, 4, and 6 days of culture in the presence of 10(-2) M azelaic acid.

Cutaneous horn is the clinical term for a circumscribed, conical, markedly hyperkeratotic lesion. We report a case of cutaneous horn occuring on the face in a 81 year old women. An about 1.2 X1.3 cm sized dark brownish conical horn was developed on her face 1 year before. Histopathologic findings showed marked hyperkeratosis, parakeratosis, and papillornatosis of the epidermis, and some cells of straturn mslpighii showed pleornorphism and nuclesr atypis. This case was considered to be cutaneous horn arising from actinic keratosis, and we performed minimal local excision.

We report a case of multiple xanthogranuloma occurring ori the scalp in a 33 years old wornan. Multiple yellowish papules were developed on her scalp 3 months ago. Histopathologic findings showed massive granulomatous infiltrations of foamy histiocytes Touton giant cells in the dermis, and these cells were positive for lipid stain. This case was considered to be multiple xanthogranuloma in an adult, and treated by sur- gical excision.
