A clinical study was made on the 28 cases underwent prostatectomy during the 5 year-period from 1964 to 1968. The results are summarized as follows: 1. The patient underwent prostatectomy revealed increasing tendency in incidence, residual urine in average and being usually in the age range between 60 and 70 years. 2. The degree of prostatic enlargement was mostly grade 11 on rectal palpation and the removed prostate was 49. 3gm. in average weight. 3. Blood loss attributable to the operative manipulation was 1143 cc. in average. The patients underwent prostatectomy were discharged on the average 21.3 days postoperatively in which postoperative indwelling catheter was left in place for 15.3 days in average. 4. Postoperatively the convalescence was uneventful and the residual urine was disappeared or decreased markedly. 5. In the patients underwent prostatectomy via retropubic approach operative blood loss was mild and postoperative duration of indwelling catheterization was short as compared to that via the suprapubic approach. 6. No serious complication other than epididymitis developed in a few patients was observed postoperatively. 7. Suprapubic prostatectomy was found to be suitable for the patient with marked prostatic enlargement while the retropubic one yielded less tissue damage and somewhat rapid postoperative convalescence as compared to the former.

Hospitals have been very susceptable to changes in external environment. Accordingly, they have been experiencing great financial difficulty due to low insurance rates and increasing competition. As a remedy, hospitals have attempted to use computer in a strategic manner. Such system is called strategic information system (SIS) , and order communication system (OCS) is an example of SIS in hospital setting. While OCS has known to be effective in reducing waiting time for outpatients, many hospitals are reluctant to introduce this system mainly because there are no real data or methods for justifying the cost of the system. Cost-benefit analysis has been traditionally used for such purpose, but this method deals with limited portion of benefits and therefore not very useful for analyzing the economic feasibility of SIS. In this paper, information economics tools which expand cost with value was used to analyze the economic feasibility of OCS. To assist the analysis, financial simulation model was developed using simulation package, called IFPS (Interactive Financial Planning System).

Aneurysmal bone cyst is a rare, non-neoplastic condition, which was first coined by Jaffe and Lichtenstein in 1942. Clavicle is an unusual site for aneurysmal bone cyst. Authors present a case of aneurysmal bone cyst which was found in the right clavicle of a 5 years old boy, because of its rarity of site of predilection.

Experiments were performed to investigate the effects of pinealectomy on the renin-angiotensin system in Sprague-Dawley rats. The results obtained were as follows. 1) There was no differences of systolic blood pressure, heart rate, water intake, and plasma electrolytes between pinealectomized and sham-operated rats. 2) Renin activity in plasma and pituitary gland did not differ in two experimental groups. 3) The pituitary gland contained the renin activity of about 50pg AI/hr/mg of wet weight. The results suggest that the pineal gland has no correlation with cardiovascular and renin-angiotensin system.

BACKGROUND: Antihypertensive effect and safety of the newer, long acting, nonsulfhydryl angiotensin converting enzyme inhibitor, lisinopril, were studied. METHODS: Twenty eight patients of mild to moderate essential hypertension were administered 10-20mg of lisinopril once daily for ten weeks. Patients were evaluated every two weeks concerning the changes of blood pressure and pulse rate in the sitting position and also any untoward sumptoms and signs attributable to the side effect. Chest X-rey, ECG and laboratory examination were performed in principle two times before and after the completion of medication. RESULTS: The blood pressure declined from 165.4/107.6mmHg to 141.3/92.4mmHg at the end of ten weeks of medication, thus the reduction of 24.1mmHg of systolic pressure and 15.2mmHg of diastolic pressure were observed and the overall effective rate was 85.7%. The pulse rate and laboratory findings were not sigificantly changed before and after the administration of lisinopril. The side effects were observed in 2 cases(7.1%) of mild dry cough and in 2 cases(7.1%) of transitory mild headache and in 1 case(3.6%) of dizziness but no one discontinued medication due to adverse effects. CONCLUSION: Lisinopril proved effective and safe in the treatment of mild to moderate essential hypertension.

This study was undertaken to investigate some mechanical properties of the skin with special relatio to pH. The abdomenal skin of guinea pig was prepared and cut into appropriate skin strips(1.5mm*15mm). The pieces of skin strips were then suvject to measurement (stretching and vreaking load) using a rheometer after treatment in various pH vuffers and humectant solutions (lactic acid, PCA, citric acid). The result are summarized as follows ; 1. Treatment of the skin in the extreme acidic (pH3) solution showed significant deformity (swelling and shrinkage in length). 2. The overall measurements after treatment in the humectant solutions were not significantly different from those in standard vuffer solutions. 3. The stretching was maxiaml at pH7 and minimal in the extreme ranges of pH(pH 3 and pH11). 4. The measurement of vreaking load showed minimal value at acidic pH3 and revealed linear increments as pH increased.

OBJECTIVE: To investigate the preterm labor & preterm infants care in Kwangju and Chonam. METHODS: A study was conducted for 2,360 newborns who were born at four main hospitals in Kwangju and chonam from January 1, 1995 to December 31, 1997. Data were collected by review of hospital records. RESULTS: 1. The survival rate was 6.90% at 23~34 weeks, 38.60% at 27~28weeks and 90.67% after 31wks. 2. The survival rate divided according to birth weight were 8.89% below 1,000gm, 57.14% in 1,001~1,500gm, 86.75% in 1,501~2,000gm and 93.37% over 2,000gm respectively. 3. Clinical causes of neonatal death were RDS(48.84%) hyperbilirubinemia (20.74%), sepsis(11.95%) and pneumonia(9.67%). 4. Incidence of RDS was 23.22% and it's neonatal mortality was 36.28%. CONCLUSION: The survival rate of preterm birth in Kwang-Ju and Chon-nam was still lower than data from advancing countries, and main cause of neonatal death was respiratory distress syndrome.
