Although a variety of agents have been introduced for the treatment of hypertension, the ideal drug has not yet been discovered. However, among the agents available, prazosin hydrochloride (Minipress(R)) appears to be accepted by the majority of physicians as it lowers blood pressure effectively with relatively low incidence of side effects. It has been considered that the hypotensive effect of prazosin is a result of peripheral vasodilation due to direct relaxation of vascular smooth muscle and blockade of alpha-adrenergic receptors in the arteriolar smooth muscle. Following the development of prazosin. many trials have been designed to potentiate its hypotensive effect by the combination with other agent, especially thiazide or beta blocker. Minizide(R), a preparation that thiazide is added to prazosin, is an example. The antihypertensive effect of Minizide(R) was evaluated in 30 hypertensive subjecs. The results were as follows; 1. The systolic and diastolic blood pressure were effectively lowered in both supine and standing position with the overall response rate of 86.7% as judged to be responsive in one that lost systolic pressure more than 15 mmHg and distolic pressure 10 mmhg. Among 30 cases 18 cases could be maintained with their diastolic pressure below 90 mmHg and 24 cases with their diastolic pressure below 100 mmHg by the end of 8th week of treatment with the daily dose of minizide(R) from a half tablet to two tablets. 2. During the period of 8 weeks, troublesome postural hypotension was not observed in any case. The pulse rate was not accelerated significantly by Minizide(R) treatment. 3. Minimal side effects were recorded in 5 cases; two of mild nausea, one of slight dizziness, one of minimal gastrointestinal irritation symptom and one of mild glucosuria. neither of them hindered the authors from finding the study.

The investigation of systolic time intervals and hemodynamics was performed in 42 patients with liver cirrhosis by noninvascive methods. The patients were divided into four groups according to the presence or absence of anemia and/or ascites: i.e. group I; cirrhosis without anemia and ascites, group II; cirrhosis with ascites only, group III; cirrhosis with anemia only, and group IV; cirrhosis with ascites and anemia. In the resting state of the patients, the systolic time intervals and hemodynamic data were measured by the high speed simultaneous recordings of electrocardiogram, phonocardiogram, carotid and femoral arterial pulse tracings, and compared with those obtained from 155 normal adult subjects. 1. The pulse were increased considerably in group IV, and diastolic blood pressure was elevated in group II with significance. 2. The stroke volume and cardiac output were increased significantly in group III. 3. The peripheral resistance was reduced particularly in group III, and the volume elasticit coefficient was decreased in group IV. 4. The QS1 interval was prolonged significantly in group II and IV, but QS1 interval corrected by multiple regression equation proposed by our laboratory (illustrated in the text) did not show significant difference compared with that of normal subjects. 5. The left ventricular ejection time(LVET) and total electromechanical systole(QS 2) appeared to be shortened in group II and IV, but the corrected LVET and QS 2 were not different significantly from those of the normal subjects

Nonunion of fractures of forearm bone occurs frequently. These patients usually suffer from pain and functional disturbance of the hand and forearm. With the introduction of compression plate for the treatment of nonunion at the Campbell Clinic in 1959, a modification of the Nicoll graft was advised. The authors analysed 23 cases of the nonunion of forearm bone, in which military injured patients were admitted and treated by bone graft with internal fixation using various devices in Department of Orthopaedic Surgery of Korea Veterans Hospital from Sep. 1983 to Aug. 1988.

BACKGROUND: Vitiligo is an acquired depigmentary disorder characterized by loss of melanocytes from the epidermis. Autografting using the suction blistered epidermis technique is one of the surgical modalities of vitiligo treatment, and has been successfully used by several authots. OBJECTIVE: The purpose of this study was to evaluate the effect of the autografting using the suction blistered epidermis technique for the treatment of vitiligo. METHODS: 142 sites from 39 patients with vitiligo were treated with autografting using the suction blistered epidermis technique. The recipient sites were prepared by freezing with liquid nitrogen of the sites 48 hours prior to grafting. RESULTS: Better results were seen in cases with the following Factors: a) cases where the disease had been present for more than 3 years b) the post-operative period had been Longer than a year c) the Lesional sites of the vitiligo were on the trunk and neck rather than the neck and extremities d) the vitiligo had affected the grabous rather than the hairy areas on the face. However, there were no differences between the clinical types(such as generalized, localized, and segmental) in the success rate of treatment. Preopera'tive PUVA or post operative PUVA also did not affect the statistical results. CONCLUSION: On autografting using the suction blistered epidermis, it is better to select the patients who have had the disease for more than 3 years, and graft the epidermis which has increased melanocytes by preoperative PUVA for good treatment results and even pigmentation.

Mitomycin C (MMC) is an antimetabolite, antibiotic which prevents the proliferation of fibroblast and fibrosis by inhibition of DNA-dependent RNA synthesis. It has been used to increase the success rate of filtering surgery. We performed trabeculectomy and peripheral iridectomy with 0.4 mg/ml MMC application for 3 minutes in poor prognostic glaucoma patient, 26 eyes of 24 patients from February 1992 to December 1994. The postoperative change of intraocular pressure (IOP) and complications were followed up from 3 to 30 months (mean 12.4 months). The preoperative and postoperative mean IOP after 24 months were 32.3 +/- 11.4 mmHg and 12.7 +/- 3.1 mmHg, respectively. The decrease rate of IOP was 60.7% and the success rate was 71.7%. The postoperative complications were 15 eyes including 5 eyes of shallow anterior chamber, 5 eyes of hyphema, 2 eyes of conjunctival wound leakage, one eye of bleb rupture, one eye of choroidal detachment, and one eye of cataract formation.

Rosacea is a disease of skin and eye that is widely underdiagnosed by ophthalmologists. Rosacea is a common chronic skin disease in Caucacian, affecting flush areas of the face that include the skin, cheeks, nose, and forehead. Ocular manifestations of rosacea mainly involve the eyelids, conjunctiva, and cornea. These include blepharitis, meibomitis, chalazia, styes, and diffusely hyperemic conjunctiva. The cornea is involved with superior punctate epithelial erosions and is most severely involved by a peripheral vascularization, usually of the lower twothirds of the cornea followed by subepithelial infiltrates. A 18 year old Korean lady was found to have hyperemic conjunctiva, chronic recurrent multiple erythematous pustular skin lesion in the face. Systemic administration of tetracycline and penglobe resulted in marked improvement in the signs and symptoms of disease. Topical corticosteroid 0.5% and chloramphenicol 0.5% also improved the manifestations of ocular rosacea.

Journal of the Korean Ophthalmological Society 1988;29(4):639-647
Behcet's disease is a chronic, multi systemic disorder affecting mainly young, adult males. The clinical course of Behcet's disease is characterized by exacerbation and remissons of unpredictable duration and frequency. The common underlying histopathologic lesion is a vasculitis. Loss of vision in Behcet's disease is one of the most frequent and serious of its mainfestations. It was shown as follows: 1. The sex distribution was 261 males(37.5%)and 435 females(62.5%), and this disease occured more often in women than men with a ratio of 1.7 to 1. 2. The mean age of onset was 29 year old and the age of onset reached its peak in the twenties and thirties(67.0%). 3. In topographic distribution, 599 patients(86.1%) were from Seoul, Kyonggido, Inchon, and rests of patients were from Kangwondo, Kyongsangnamdo, Pusan in order. 4. In Shimizu classification, incomplete type was the most numerous with 256 patients(36.8%), and the probable, possible and complete type were observed in order. 5. In major symptoms, oral lesion showed the highest frequency with 674 patients(96.8%), skin lesion in 416 patients(59.8%), genital lesion in 390 patients(56.0%) and ocular lesion in 93 patients(13.4%). In minor symptoms, the arthritis showed the highest frequency with 168 patients(24.1%), Oral lesion appeared in 615 patients(88.4%) and ocular lesion in 22 patients(3.2%)as the initial symptom. 6. Ocular lesions appeared in 158 eyes among 93 patients who had it. The mean age of onset of ocular lesions was 32 yeat old. Cases which the symptom was limited to right eye appeated in 16 patients(172%), the left eye in 12 patients(12.9%) and bilateral in 65 patients(69.9%). It took 43 months in average from the appearance of the initial symptom to that of the ocular lesion and in 22 patients(23.7%), the ocular lesions appeared at first. In ocular lesions, iritis and hypopyon which appeared in 127 eyes(80.4%) showed the hilithest frequency and the vitreous opacity, complicated cataract, retinal degeneration, conjunctivitis, complicated glaucoma, retinal hemorrhage and chorioretinitis were observed in order. 7. The visual acuity of 47 eyes(32.7%) belowed 0.01 and 25 eyes which were treated over 24 months showed marked loss of vision, mostly. 8. In 10 among 93 patients with ocular lesion, HLA antigen was examined, HLA-B5 detected in 6 patients, HLA-Bw51 in 4 patients and HLA-DRw8 in 5 patients.

The purpose of this study was to examine professors’ and students’ perceptions of curriculum that fosters character in medical school. ‘Character’ can be defined as a desirable personality and the ability to be a good person. A total of 264 subjects (professors=131, students=133) participated in the study. Survey questions were divided into the three parts (education needs, factors of character, and curriculum management strategy). Data were analyzed by using t-test and one-way analysis of variance. Both professors and students recognized the need for character education. Professors were more aware of the need for education than students (t=4.35, p<0.01), and clinical professors were more aware of the need for education than basic medical science professors (t=3.48, p<0.01). Premedical students were more aware of the need for character-centered education than medical students in the later stages of their education (t=3.41, p<0.01). Professors and students commonly referred to ‘consideration and communication’ as the most important factor in building character. Professors considered ‘self-regulation’ more important than the students recognized, while students perceived ‘wisdom’ as more important than the professors did. There was a difference in preference for curriculum development (creating new subjects vs. revising existing subjects) between the two groups. However, both groups agreed on the teaching and evaluation methods. In conclusion, both groups acknowledged the need for character education. However, there were differences in perception on the major factors of character and preference for curriculum development. The results of this study may assist in designing character education in medical education.
