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.

PURPOSE: To evaluate the degree of contrast enhancement of intracranial tumors on delayed (6-8min.) MR imaging after administration of Gd-DTPA. MATERIALS AND METHODS: Both immediate and delayed post-contrast MR imagings were studied prospectively in 35 patients. with brain tumors (11 gliomas, 6 meningiomas, 4 neurinomas, 5 parencymal metastases, 5 hemangioblastoma, 4 others) at either 0.5 T or 2.0 T unit. After precontrast TI-, proton-density, and T2-weighted spin echo images were obtained, each patient underwent Tl-weighted imaging immediately following infusion of 0.1 mmol/Kg of Gd-DTPA. Subsequently, the second postcontrast Tl-weighted images were obtained with no additional injection of the contrast media. Time-interval between the postcontrast immediate and the delayed images was approximately 6-8 minutes. Degree of contrast enhancement of the lesions was assessed both visually and quantitatively. For quantitative study, contrast enhancement ratio(CER) of tumors was calculated in both immediate and delayed post-contrast images. RESULTS: There was stronger visual enhancement in 7 of 11 cases with gliomas and 3 of 5 cases with parenchymal metastasis on delayed images when compared with immediate images, whereas all 10 cases of extraaxial tumors(meningiomas and neurinomas) showed decreased enhancement on delayed images. Quantitatively, mean CERs of gliomas and metastases were higher on delayed study than on immediate study by 20. 5% and 49.2%, respectively. Extraaxial tumors showed decrease of CER on delayed study by 19.7% as compared with that of immediate study. Hemangioblastomas showed visually poor enhancement on delayed image in 4 cases and equal enhancement on both immediate and delayed images in remaining one case, and quantitatively demonstrated decrease of CER on delayed study by 15.4%. CONCLUSION: Since there was more conspicuous contrast enhancement in many intraaxial tumors such as gliomas and metastases on 6-8 minutes delayed post-contrast MR study, the delayed post-contrast study may be needed in some intraaxial tumors for their characterization, and may also be helpful for the differential diagnosis between intraaxial and extraaxial tumors.

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.
