The study was undertaken to evaluate the protective effect of epinephrine on renal radiation injury. For theexperiment, 50 rabbits were divided into 3 groups; the first group of 9 rabbits were used to determine theavailable dosage of epinephrine as preliminary study, the second group of 18 rabbits were used to evaluate theradiation injury as radiation group, which were received a single dose of 2,000 rads of radiation on unilateralkidney using 60 Co teletherapy unit, and the third group of 23 rabbits were used to assess the radioprotective effedct of epinephrine as radiation

The determination of the degree and ability of recovery of obstructive hydronephrosis is important in treatment and prediction of prognosis. Among the various methods in determination of the status of kidney, intravenous pyelography is the most important tool to evaluate the morphological and functional changes of kidney in vivo. The purpose of this experiment was the determination of process and recoverability of hydronephrosis depend on duration of unilateral uretreal obstruction. For the experiment, 32 rats were divided into 2 groups; the first group of 12 rats were used to determine the process of hydronephrosis during 1 to 4 weeks of unilateralureteral ligation and the second group of 20 rats were used to determine the recoverability of hydronephrotic kidney depend on same duration of ureteral ligation following relief of ligation. Intravenous pyelography as undertaken and renal angiography, gross and microscopic examination were added. The results obtained are summarized as follows; 1. Kidney enlargement and pelvic dilatation were progressively increased with a relation to duration of ureteral obstruction until 4 weeks. 2. Renal excretory function is not impaired until 3 weeks obstruction, but rapidly impaired to nonfunctioning in 4 weeks obstruction. 3. Renal recovery was possible following relief of ureteral ligation within 3 weeks of ureteral obstruction, but histopathological and functional recovery were impossible in 4 weeks of ureteral ligation. 4. There is no direct correlation between duration of obstruction and recoverability following relief within 3 weeks of uretral obstruction. 5. Intravenous pyelographyis a simple and accurate method to determine the degree of obstructive hydronephrosis and to evaluate morphological and functional recovery of kidney following relief of obstruction.

Five patients with brain tumors have been treated with an afterloaded removable Iridium-192 interstitial brachytherapy using Brown-Roberts-Wells stereotactic system. There were two cases of glioblastoma multiforme, one case of recurrent glioblastoma multiforme, one case of recurrent metastatic brain tumor and one case of recurrent astrocytoma grade II. The patients were treated by combination of surgery or stereotactic biopsy and external radiation previously. Tumor doses ranging from 4100 to 8600 cGy were delivered to these patients. There was no death and 4 patients showed definite tumor regression 3 months following interstitial brachytherapy. The method was safe and appeared to be effective madality to achieve local control of brain tumors.

PURPOSE: The limited information regarding preservation of erectile function following castration is based on self-reports by castrated patients. Therefore, we evaluated the erectile status in 38 patients with advanced prostatic cancer. MATERIALS AND METHODS: Castrations were achieved by bilateral orchiectomy, estrogen therapy of both. Patients answered the questionnaires regarding the medical status and erectile function before and after castration, and the blood levels of testosterone were assessed. Especially in seven patients, penile circumference and erection quality were monitored during the visual sexual stimulation. RESULTS: 11 patients(58%) out of 19 potent men achieved functional erection after castration. Mean serum testosterone level was 0.31 +/-0.19ng/ml in men who were potent after castration and 0.06+/- 0.04ng/m1 in those not potent(p<0.05). No statistically significant differences were noted in age, interval after castration, method of castration, degree of gynecomastia, stage of prostatic cancer and doing radiation therapy between the men who did and did not achieve erection(p>0.05). CONCLUSIONS: Following castration, sexual potency and libido decreased markedly in most cases, but 58% retained some degree of normal sexual potency. And, statistically significant difference was noted only in serum testosterone level between the men who did and did not achieve erection.

The Korean Society of Therapeutic Radiology has periodically conducted a national survey on the status of radiation therapy facilities in Korea. This paper summarized survey data on the status of radiation therapy facilities, manpower, megavoltage equipments, patient load, types of procedures performed and characteristics of the patients treated.

Brachytherapy has been proved to be an effective method for the purpose of increasing radiation dose to the tumor and reducing the dose to the surrounding normal tissue. In head and neck cancer, the rationale of brachytherapy is as follows; Firstly, early small lesion is radiocurative and the major cause of failure is local recurrene. Seondly, it can diminish evidently the dose to the normal tissue especially masseteric muscle and salivary gland. Thirdly, the anatomy of head and neck is suitable to various technique of brachytherapy. On background of accumulated experience of LDR iridium brachytherapy of head and neck cancer for the last 15 years, the author reviewed the history of radioisotope therapy, the characteristics of radionuclides,and some important things in the method, clinical technique and treatment planning. The author analyzed the clinical result of 185 cases of head and neck cancer treated in the Korea Cancer Center Hospital. Finally the fu ture prospect of brachytherapy of head and neck cancer is discussed.
