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.

We studied the degenerative changes of acetabulum, examining the acetabular articular cartilage at weight bearing dome area from the hips of 25 avascular necrosis of femoral head cases. Histological- histochemical studies demonstrated 4 mild, 19 moderate and 2 severe grade of degenerative arthritic change. This has confirm that even in early stage of avascular necrosis of femoral head, there are degenerative arthritis in acetabular cartilage. This may influence the prognosis of bipolar hemiarthro- plasty in avascular necrosis of femoral head patient.

3.Incidence of Anti - Ro Antibodies in Patients with Systemic Lupus Crythematosus.
Korean Journal of Dermatology 1987;25(2):209-212
We examined the incidence of anti-Ro antibodies with sera from 60 Korean patients with systemic lupus erythematosus(SLE) by double immunodiffusion. Among these 60 sera tested, 31(51.7%) showed evident immunoprecipitations against Ro antigen on the Ouchterlony plates. Several recent studies indieate that the anti-Ro antibody occurs much less frequently in Occidental lupus patients(around 30%) than in Japanese lupus patients (50%). These data may be suggestive that the racial or ethnic baekground might be an important factor determining the serological, and perhaps the clinical features of SLE.

5.A Clinical Observation on Tumors of the Renal Pelvis and Ureter.
Korean Journal of Urology 1982;23(8):1105-1110
Primary tumor of the renal pelvis and ureter is relatively rare disease, but usually malignant. It's prognosis is dependent upon the early detection, accurate diagnosis, procedure for treatment, and tumor grade and stage. Therefore, urologist should endeavor after accurate diagnosis and definitive treatment. A clinical observation was done on the 11 patients with renal pelvic tumor and the 3 patients with ureteral tumor at the Department of Urology, Kyungpook National University Hospital during the period of 4 years from January, 1978 to December, 1981. The results were as follows: 1. There were 9 men and 5 women, giving a ratio of 1.8 to 1. The average age at presentation of the 14 patients was 51.4 years. 2. On excretory urogram, nonvisualization of the kidney was the most prevalent sign in 10 patients. Retrograde pyelogram was done in 11 patients in whom findings of IVP were not sufficient for diagnosis. Renal angi0graphy was done in 9 patients. 3. Urine cytology was positive in 2 of 14 patients. 4. Of the 13 patients treated, 12 were proved to have transitional cell carcinoma, and 1 was leiomyoma. In 3 of the 11 patients with renal pelvic tumor, Concomitant ureteral tumor was present at diagnosis. And in 2 of the 11 patients with renal pelvic tumor developed subsequent urothelial tumors in the ureter and/or bladder after simple nephrectomy. 5. Nephroureterectomy including resection of a bladder cuff was done in 11 patients, and in 2 of these was also performed lymphadenectomy. Simple nephrectomy was done in 2 patients with renal pelvic tumor under the misdiagnosis of renaltuberculosis. 6. Postoperative complications developed in 3 cases, wound infection, pneumothorax, and death, in each case.

7.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.

We report one case of bilateral naviculo-medial cuneiform coalition in ten year old girl. She complained of pain in the medial aspect of the mid-foot related to long periods of standing and activity. Routine roentgenographs, specifically lateral views showed a bony bridge between the navicular bone and medial cuneiform. A biopsy revealed as fibrocartilaginous tissue. The bony bridge consists about one third in lateral view and 30 degree cephalad tilting in the antero-posterior view. Bilateral resection arthroplasty, with interposing flesh muscle fibers of the abductor hallucis, was performed for restoration of motion in the naviculo-medial cuneiform joint and relief of localized pain. Four months after surgery, pain around the mid-foot had almost complete subsided. One year postoperative, neither recurrence nor disability was observed. We will discuss the diagnosis and treatment of this rare case of bilateral naviculo-medial cuneiform coalition.
