1.Clinical Study on the Effects of Antihypertensive Drugs.
Korean Circulation Journal 1973;3(2):45-56
Evaluation of several antihypertensive regimens involving reserpine, hydrochlorothiazide (Esidrex(R)) and clonidine (Catapres(R)) was conducted on 230 subjects with mild to severe hypertension. Chlordiaxepoxide (Librium(R)) which is a sedative was also administered to observe the effect in patients with mild labile hypertension. The results obtained were as follows; 1. All five regimens of chlordiazepoxide, reserpine, hydrochlorothiazide, hydrochlorothiazide plus reserpine and hydrochlorothiazide plus clonidine produced a significant decrease in average mean arterial pressure (systolic+diastolicc pressure/2) compared to control values (p<0.01). 2. Hydrochlorothiazide plus clonidine was the most effective pressure lowering regimen, resulting in an average fall of 39.3 mmHg in average mean arterial pressure and obtaining excellent result in 28.6% of the cases. 3. The order in the pressure lowering effect was hydrochlorothiazide plus clonidine, hydrochlorothiazide plus reserpine, hydrochlorothiazide, reserpine, and chlordiazide 4. There was no significant difference between hydrochlorothiazide plus clonidine and hydrochlorothiazide plus reserpine (p>0.1). 5. More reduction in diastolic pressure than systolic was observed with hydrochlorothiazide plus clonidine. 6. The results of hydrochlorothiazide alone, hydrochlorothiazide-reserpine and hydrochlorothaizide-clonidine were better than those of chlordiazepoxide and reserpine alone in patients with fundoscopic findings of Keith-Wagener Grade II. 7. There was difference in pressure lowering effect with hydrochlorothiazide plus clonidine between the group with and without albuminuria. 8. Hydrochlorothiazide plus clonidine were extremely effective in patients with severe hypertension, hydrochlorothiazide plus reserpine in patients with moderately severe hypertension, and reserpine and hydrochlorothiazide alone in patients with mild hypertension.

2.Concept Analysis of Comfort.
Journal of Korean Academy of Adult Nursing 1999;11(1):169-178
The concept of comfort has been regarded as a core concept of nursing and it has been frequently used as one of main goals of nursing care. Promoting comfort has been a very important objective in clinical nursing practice. There have been some ambiguities in defining the concept of 'comfort" among nursing scholars. Therefore it was necessary to analyse the concept of comfort for clearer definition to be able to share among scholars. This study is an attempt to analyse concept of comfort and to do it according to a series of concept development processes described by Walker and Avant. Based on the results of the study, the attributes of scope, precedence and consequence of comfort were identified : 1. Attributes 1) stability 2) directionality 3) equilibrium 4) firmness 2. Scope 1) physical 2) social 3) emotional 4) spiritua~ 3. Precedence and Consequence 1) precedence (1) instability (2) unsatisfied needs 2) consequence (1) physical & psychological relaxation (2) enhancement of self-worth (3) enhancement of self-efficacy (4) satisfied needs.

4.The Experimental Studies on Cardiac Glycoside(Ouabain) and Electrolytes.
Korean Circulation Journal 1971;1(1):1-22
Acute digitalization with ouabain were performed 28 times in 20 intact Mongrel dogs, who were devided into four groups : i.e. 1) Control group; Acute digitalizations were performed to observe the changes of the plasma potassium and sodium concentrations and the concomittent electrocardiographic findings. 2) Group 1;-Electrolyte solution, either KCl or NaCl, was infused during acute digitalization to observe the influences of these ions on the actions of cardiac glycoside, especially arrhythmia producing action. 3) Group 2 ; -The K depleted group and the Na depleted group was each made by the measure of diet control and the usage of oral diuretics to observe the influences of the state of depleted electrolyte (K or Na) on the action of cardiac glycoside during acute digitalization. 4) Group 3 ; -The intravenous infusion of either KCl or NaCl solution was introduced as the cardiac arrhythmia by the ouabain was produced to observe the effects of these ions on the digitalis induced arrhythmia. The results obtained were summarized as follows. (1) The arterial plasma concentration of potassium was increased during acute digitalization. The rise occurred at early stage, and the maximal increase of potassium was observed at the ventricular tachycardia. The average increase was 0.65 mEq/L as compared to control value (p<0.05). The arterial plasma concentration of sodium was reduced during acute digitalization. The fall occurred following the rise of plasma K level. The maximal reduction of sodium was observed after ventricular tachycardia, and the average decrease was 5.2 mEq/L as compared to control value (p<0.05). (2) Rapid increase up to toxic level of the plasma potassium concentration occurred occasionally during acute digitalization in the group with KCl infusion. This result was best explained due to the inhibitory action of cardiac glycoside on the K transport. (3) The interesting change was on T wave, which showed the peaking at late portion. This change occured in 60.6% during digitalization with ouabain, and paralleled mostly, but not consistently and even sometimes inversely, with the shift of plasma potassium concentration. It is tempting to assume that the change of T wave was resulted from an altered potassium gradient across the myocardial cells rather than a ssuming the changes of the plasma K level. (4) Just prior to intoxication, the marked prolongation of PR interval and ST depression were observed in about 70~80% of the cases studied. These changes might be applicable to a clue of the cardiac glycoside overdosage. (5) The intravenous infusion of KCl suppressed markedly the arrhythmia producing action of the cardiac glycoside, and resulted in prompt and dramatic abolishing, of digitalis induced arrhythmia. The intravenous infusion of KCl solution, however, produced A-V block or dissociation occasionally. This finding would be likely resulted from the additive or synergistic action of K and cardiac glycoside in suppressing A-V conducting system. (6) The NaCl infusion affected nothing to the arrhythmia producing action of cardiac glycoside. (7) The K depletion reduced markedly the threshold of the heart to the toxic effects of cardiac glycoside. (8) Potent diuretics in the state of deficient diet would produce clinically significant hypopotassemia and hyponatremia or both. The inducced hypopotassemia may provoke serious cardiac arrhythmia in the digitalized patients or animals.

Journal of the Korean Balance Society 2006;5(2):320-324
Optic ataxia is characterized by an impaired visual control of the direction of arm reaching to a visual target, accompanied by defective hand orientation and grip formation. In humans, optic ataxia is associated with lesions of the superior parietal lobule, which also affect visually guided saccades and other forms of eye-hand coordination. A 67-year-old woman presented with sudden, unilateral, direct optic ataxia in the right homonymous half field and saccadic abnormalities which consisted of prolonged latency, undershoot dysmetria, and decreased velocity. Brain MRI showed a left parieto-occipital watershed infarction. It is suggested that lesions of the superior parietal lobule and the adjacent parietal eye field are responsible for optic ataxia and saccadic abnormalities, respectively.

Tumor angiogenesis has been found to have prognostic significance in many tumor types for predicting an increased risk of metastasis. We assessed tumor vascularity in 28 cases of borderline malignancy and 71 cases of carcinoma of the ovary which had been resected and diagnosed, using the highly specific endothelial cell marker CD34. The numbers of microvessels were counted in 200 magnification in three highly vascularised areas. The numbers of microvessels in carcinomas were higher than that in the borderline malignancy of serous and mucinous tumors. The number of microvessels of mucinous carcinomas was significantly higher than that of serous carcinomas. There were neither significant differences in the number of microvessels according to histological tumor types (p=0.075) nor significant differences in the number of microvessels according to FIGO stages (p=0.072). But in serous carcinomas, the number of microvessels was higher in the FIGO III-IV stage than in the FIGO I-II stage (p=0.017). This study showed higher neovascularization in malignant tumor than borderline malignancy, and in the advanced stage (FIGO III-IV) than less advanced stage (FIGO I-II) of serous carcinomas.

The distal tibial physes begins its closure about 18 months prior to complete cessation of the tibial growth, closing first in its midportion, then medially, and finally, laterally. So the patterns of the ankle fracture during this period would be different from those of the adult or the children before this period. During the six year period from 1983 to 1988 at the department of orthopedic surgery, college of medi-cine, Hallym University, we found and analysed 54 adolescent patients with the ankle fracture which developed before the closure of the distal tibial growth plate, which were followed up more than 1 year. The results were as follows 1. During the 6 year period of this study, the adolescent ankle fracture comprise 4.4% (54 cases) of all the ankle fractures(1158 cases). Injury occurred more often in male than in female(44 versus 10). The mean age was 13.7 years. 2. The most common cause of injury was traffic accident being in 26 cases(48.1%), the next was slip down accident in 11 cases, and the third was sports activity in 10 cases. 3. The incidence of the adoescent ankle fractures using the Salter-Harris classification revealed 20 (37%) type II, 7 (13%) type III, 5 (9.3%) type IV, and 4 (7.4%) type I and that using the Dias and Tachdjian classification revealed 14 (25.9%) Supination-Inversion, 10 (18.5%) Supination-External rotation, 7 (12.7%) Pronation-Eversion-External rotation, and 1 (1.9%) no adjustable fracture. There were 9 (16.7%) Tillaux and 9 (16.7%) triplane fractures, which were belonged to both classifications 4. The treatments performed were closed reduction and cast immobilization for 28 cases (51.9 %), open reduction and internal fixation for 20 cases (37%), and closed reduction and percutaneous pinning for 6 cases. 5. There were complications experienced in 9 cases, which were 3 premature epiphyseal closure, 3 joint surface incongruity, 2 angular deformity, and 1 leg shortening. 6. For the prevention of the complication, the treatment of the adolecsent ankle fracture should be treated like as adult fracture.

The Journal of the Korean Orthopaedic Association 1989;24(1):156-160
Although several histopathological changes have been developed in frozen shoulder, frozen shoulder is mostly accompanied by the changes of the rotator cuff which has the most important function in movement and has a role in stabilizing the shoulder joint. The changes of the rotator cuff in frozen shoulder have not been reported in Korea yet, but Simon reported that there was an attenuation of the rotator cuff in frozn shoulder. Accordingly, we observed the changes of the rotator cuff in frozen shoulder by ultrasonography, which has no rsdiation exposure and is non-invasive. The authors practiced the shoulder ultrasonography on 36 patients with a pain and limitation of motion in shoulder at the Dept. of Orthopedic Surgery, Hangang Sacred Heart Hospital, Hallym University, from March in 1988 to August in 1988. The results are as follows ;1) Ultrasonography is thought to contribute a great deal in detection of the changes of the rotator cuff, especially of the thickness of the rotstor cuff. 2) Among 36 patients, the thickness of the rotator cuff of 35 patients was 6.494+1.008 mm (M+SD) in the affected shoulder and 6.475+1.052 mm(M+SD) in the unaffected shoulder. In only one pstient, the thickness of the rotator cuff was 1.68+0.58 mm(M+SD) in the affected shoulder and 553+1.16mm(M+SD) in the unaffected shoulder. Theres no significant change in the thickness of the rotator cuff measured by ultrasonography in frozen shoulder. 3) Ultrasonography is an excellent diagnostic method in detecting the rupture of the rotator cuff in frozen shoulder.
