Trimazosin Hydrochloride is a new orally active antihypertensive agent derived from the Quinazoline family, related chemically and pharamacologically to parazosin, but unlike its precedecessor, no first-dose syncope has been note, and no tolerance in the management of long term hypertensive patients. The antihypertensive effect of Trimazosin was observed from Oct. 1984 to Mar, 1985 at hospital of Chung-Ang Univesity as outpatient base involving a total 25 patients(Male;16, Female;9)with mild to moderate Hypertension(Diastolic B, P> or =90mmHG but< or =110mmHg). And the average age was 51.5 year(39-66yrs.) Our data demonstrate that 1) Trimazosin is an effective antihypertensive agent for controlling both systolic(166mmHg to 135.7mmHg)and diastolic(102.8mmHg to 85.3mmHg)pressure, and the mean arterial pressure was decreased from 123.8mmHg to 102.1mmHg(P%0.001). 2) We achieved significant sustained reduction in blood pressure with Trimazosin alone in 10 patients, Trimazosin plus Thoazide diuretics in 4 patients, Trimazosin plus-Beta-blocker in 5 patients, and with above triple regimensin 5 patients. 3) Side effects observed during Trimazosin theraphy(mean 3.8 months)appear to be minor and are reflection of its hemodynamic effects, (fatigability 2, dizziness 3, nausea 3 and headache 3) except one had to stop due to severe pounding headache.

communicable diseases. The purposes of the study is to estimate reporting proportion of National Notifiable Infectious Diseases(NNIDs) and investigate characteristics related to reporting using KAP(knowledge, attitude, practice) model. METHOD: We surveyed randomly selected 2,185 physicians (speciality: internal medicine, family medicine, pediatrics, dermatology, general physicians) of their knowledge, attitude, and practice of NNIDs reporting through self-administered mail questionnaires. Of them, 231 physicians responded (response proportion: 10.6%). RESULT: The reporting proportion was estimated to 27.0%. Recognition level (knowledge) of NNIDs was relatively high with proportion of 69.4%, and attitude (public health importance) of reporting was 65.8%. Multiple logistic regression analysis showed that knowledge, attitude significantly affected physicians' reporting in a positive direction (O.R. 6.2, 6.2 respectively). Whereas, senior age group, specialty (family medicine, pediatrics, dermatology) showed significantly lower reporting. General (tertiary care) hospital level of care showed significantly higher reporting practice (alpha=0.05). CONCLUSION: The NNIDs reporting proportion, 27.0% is similar with those studied recently. Continuous efforts to increase the performance level of communicable diseases surveillance system. Of those, restructuring surveillance systems considering characteristics of notifiable diseases classes must be stressed. Educational approach of physicians needs to be tailored specially to newly-designated diseases such as Group II, Designated Group NNIDs.

Osteochondritis dissecans occurs most commonly in knee joint and often in elbow, ankle, shoulder, hip than in other joint. In osteochondiritis dissecans, an area of subchondral bone undergoes avascular necrosis and degenerative change ususlly occurs in cartilage overlying it. During the course of disease, unless interrupted by treatment or spontaneous healing, the necrotic bone and cartilage seperates from adjacent bone and cartilage and together becomes loose body. To promote healing, the proper treatment is necessary before degenerative change developes. The authors reviewed 11 cases of osteochondritis dissecans which recieved treatment at Severance hospital from January 1972 to December 1981. The results were obtained as follows: 1. The incidence of osteochondritis dissecans in male was a little more frequent than that of female and 50% were observed in the age of 16 to 30 years. 2. The most common symptom and sign was pain and limitation of motion, instability senastion, tenderness, snapping sound in order of frequency. 3. The most common area involved was the knee in 9 cases, 5 cases involved the medial femoral condyle, 4 cases involved the lateral femoral condyle. The ankle and elbow was 1 case for each. 4. Eight(72.7%) of 11 cases had history of trauma. 5. Among 9 cases of knee inlovement, 5 (55.6%) cases were associated with rupture of meniscus. 6. The methods of treatment were as follows. Conservative..................................................................1 Operative Curettage and drilling........................................................6 Excision......................................................................3 Curettage and bone graft.......................................................1 Internal fixation..............................................................1 7. Conservative treatment was performed in one case, but failed. So, all 11 cases recieved operative treatment and obtained satisfactory results in 72.8%.

The treatment of pain in the back and extremities remains empirical. The application of surface electrodes to the dorsal columns of the spinal cord has been used by Shealy. The rationale. for dorsal column stimulation has been the “gate control theory” of pain proposed by Melzack and Wall. Transcutaneous electrical nerve stimulation is well recognized for its effectiveness in pain relief. The authors studied 48 cases of group A (physiotherapy, medication) and compared them with 43 cases of group B(physiotherapy, medication 'and diadynamic current), in the Department of Orthopedic Surgery, Yonsei University Hospital, from April, 1983, to June, 1984. The results were as follows: 1. Significant relief of pain was noted in group B in long term follow up of acute pain in the back and extremities. 2. In long term follow-up of group B, there was more improvement than in group A, especially when there was radiating pain in the extermities with or without back pain. 3. In long term follow-up according to the causes of the pain, there was more improvement in group B than in group A in cases of herniated nucleus pulposus and low back syndrome. From a consideration of these studies, it was concluded that satisfactory results were obtained from diadynamic current treatment for the patient with pain in the back and extremities.

STATEMENT of THE PROBLEM: Recently an innovative method of fabricating indirect restorations by gold electroforming has been developed. But the bond quality and strength of the gold coping to the porcelain is uncertain. PURPOSE of STUDY: The purpose of this study is to analyze and evaluate the electroformed gold surface for mechanical bonding between the gold and the ceramic veneering. METHODS and MATERIAL: Electroformed disks were made using electroforming technique. And the surface of the electroformed coping was analyzed after sandblasting, heat-treatment, bonding agent application, opaque porcelain firing with scanning electron microscopy and energy dispersive x-ray analysis. Results. In the analysis with SEM, Sandblasting made the sharp edges and undercuts on the electroformed surface, and after bonding agent application, net-like structure were created on the electroformed surface. In the energy dispersive x-ray analysis it is confirmed that electroformed surface contains some impurities. CONCLUSION: With the use of sandblasting and bonding agent, electroformed surface seems to be enough to bond with veneering porcelain.

Cystic parathyroid adenoma is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. This type of adenoma tends to cause increased serum level of parathyroid hormone and alkaline phosphatase, similar serum calcium level when compared to those of solid adenoma. Thanks to current radioimmunoassay and easy accessibility to serum autoanalyzer, serum calcium level and parathyroid hormone level are more easily measured, which in turn lead to more easier diagnosis of hyperparathyroidism. Also improvement in imaging and nuclear diagnostic method of parathyroid lesion are suggested to enable easy diagnosis of cystic parathyroid adenoma. A 35-year-old male presented with easy fatigability for 12 months. The serum calcium, phosphate, alkaline phosphotase were 11.5mg/dL, 1.4mg/dL, 194IU/L respectively and his parathyroid hormone level in serum was 126.42pg/mL. Neck CT showed enlargement of right lobe of thyroid gland with well defined inhomogenously enhanced density inside the right thyroid gland. The patient was diagnosed of hyperparathyroidim due to parathyroid adenoma and was surgically removed. The surgical biopsy showed cystic parathyroid adenoma. After operation his general condition was improved and serum calcium, phosphate, parathyroid hormone level were normalizd. We report a case of hyperparathyroidism caused by cystic parathyroid adenoma with brief review of literature.
