Recent reports suggest that the responses of the detrusor muscle to the hypogastric nerve stimulation and some autonomic drugs may not be identical among various species. In this study, the responses of the isolated detrusor muscle strips of the Amyda Japonica and the rabbit to catecholamines were compared, and the type of the adrenergic-receptors was investigated. The results obtained were as follows : 1. Catecholamines (norepinephrine and epinephrine) evoked only contraction in the isolated detrusor muscle of the Amyda Japonica and relaxation in the preparation of the rabbit. 2. The contraction-response in the Amyda Japonica was blocked in the presence of regitine, an adrenergic alpha-receptor blocking agent. 3. The relaxation-response in the rabbit was abolished by pre-treatment with propranolol, an adrenergic beta-receptor blocking agent. 4. Acetylcholine elicited contraction in both of the isolated detrusor muscle strips of the Amyda japonica and the rabbit, and the response was completely blocked in the presence of atropine. 5. The results described above suggest that catecholamines exert excitatory effect on the detrusor muscle of the Amyda japonica as it contains adrenergic alpha-receptors and inhibitory effect on the same preparation of the rabbit as it contains the adrenergic beta-receptors. Key Word : amyda japonica,alpha receptor, beta receptor.

We tried to analyze the status of 10 units of frozen thawed apheresis platelet concentration by 6% DMSO method for the evaluation of practical applicability. The platelet concentrations were transferred to PL-732(Baxter, USA) cryopreservation bag, and DMSO is added to those bag at slow rate until expected final 6% concentration is achieved, thereafter those were directly placed to -80 degrees C refrigerator for freezing. Someday later from I week to 1 month, those were thawed at 37 degrees C water bath, and then washed by same volume of ABO matched plasma. In the course of cryopreservation, about 7% of platelets were lost and the mean recovery rate of platelet was 93% compared with those of unfrozen status. LDH, the values of platelet lysis, and pH were within normal limits, whereas platelet aggregation test shows decreased aggregation to collagen and ristocetine compared with those of unfrozen status(p<0.05) but they were clinically acceptable. We suggest that the frozen platelets may be useful in a some clinical situation such as hematologic malignancy and solid tumor by autologous transfusion.

The incidence of acute urinary retention in females is very low but the causes are diverse. So, it is important to verify the causative diseases trough history taking, physical examination including neurologic tests and it is essential to find adequate therapeutic modalities. MATERIALS AND METHODS: We experienced 45 female patients who visited under the chief complaint of acute urinary retention and reviewed, evaluated retrospectively or prospectively during 4 years. The patients are divided 1) transient causes: immobilization after surgery, constipation, medications, herpes zoster, psychogenic causes 2) neurologic causes: cerebral concussion, peripheral neuropathy, brain tumor, herniated nucleus pulposus, spinal cord injury, previously undiagnosed diabetes 3) pelvic causes: difficult labor, uterine prolapse,, pelvic bone tumor, vaginal invasion of rectal cancer, imperforate hymen. RESULTS: Screening test were done through physical examination, history taking, routine urinalysis. Most patients recovered voiding after correction of underlying diseases. CONCLUSIONS: The patients who showed persistent retention were further evaluated through neurologic tests, urodynamics, pelvic ultrasonography and serious diseases as blain tumor, polyneuritis, metastaic pelvic bone tumor were diagnosed.

Malignant lymphoma of testis is rare, comprising 5% of all testicular tumor, but it is the most common type of testicular tumor in patients more than 5 years old. And malignant lymphoma of urinary bladder is extremely rare, while the majority of the affected patients fall within the to 60 age 40 group and is more common in female. Prognosis of the testicular lymphoma is very poor, and the interval free of disease is short and 9O % of patients die of generalized lymphoma within 2 years. Although in contrast to other nonepithelial malignant tumor, primary lymphoma of bladder carries a relatively favorable prognosis but secondary or disseminated bladder lymphoma has poor prognosis. This report concerns a case of simultaneous involvement of both testes and bladder by malignant lymphoma, which was treated with bilateral radical orchiectomy, transurethral resection of bladder and anticancer chemotherapy.

Delayed cutaneous hypersensitivity test had been demonstrated to correlate inversely with stage of disease and predict prognosis of tumor. We evaluated the delayed cutaneous hypersensitivity(D.C.H.) with Multitest CMI between the tumor group and normal control group in Department of Urology, Kosin, Medical College Hospital during the period from October 1986 to August 1988. The result were as follows: 1. D.C.H. with Multitest CMI was compared between the normal control and tumor group: mean total score of positive antigens was markedly decreased in the tumor group(11.3mm for tumor, 15.9mm for control p<0.01) and average number of positive reaction was also decreased in the tumor group(2.6 for tumor, 4.2 for control p<0.01). 2. The percentages of energic response were 11.9% for tumor and 0% for control and the incidence of hypoenergy was also increased in the tumor group (34.2% for tumor, 9% for control). 3. The percentages of Warning score were 27.6% for tumor and 6.8% for control. 4. In comparison with each antigens, there were the strongest reaction and the highest reaction with tuberculin in both group (98.3% for control, 82.9% for tumor) while the weakest reaction with tetanus (16.3% for control, 3.9% for tumor). 5. In comparison of D.C.H. between male and female, low cell mediated immunity was observed in female for the average number of positive antigens in control(4.8 for male, 3.7 for female) and for the average store of in tumor (11.7 mm for male, 9.6 mm for female). 6. In D.C.H. between age groups in control, the youth (17-25 years old) showed the strongest reaction (mean total score 19.1 mm) and 26-65 years old group had relatively stable immunity.

A clinical observation was made on 72 cases of urinary tract tuberculosis who had been admitted to the Department of Urology, Chonnam University Medical School, Kwangju, Korea, during the 6 year period from January 1, 1976 through December 31, 1981. The results were as follows: 1. During the period, there were 72 cases of urinary tract tuberculosis, 4.0% of total 1.809 patients who were hospitalized during the period. There was a tendency of significantly decreasing annual incidence of urinary tract tuberculosis. 2. Among these 72 patients, 51 (71%) belonged to the age group of 20 to 49. 3. Bilateral upper urinary tracts were affected in 17 cases, while only right urinary tract was involved in 32 cases and left one in 23 cases. 4. The initial subjective complaints were mostly of vesical irritability, such as frequency (52.8%), hematuria (29.2%) and painful urination (27.8%). 5. There were 19 patients (26.3%) who consulted 6 months through 1 year after onset of symptoms. 6. Past history or present active lesions of tuberculous diseases were noted elsewhere in 40 patients (55.6%), of which 18 had pulmonary tuberculosis. 7 Urinalysis revealed proteinuria in 77.8% of all cases, hematuria in 62.5%, pyuria in 52.8% and AFB stain was positive in 47.2%. 8. On excretory urogram, nonvisualization of the kidney was found in 29 cases (40.3%) and delayed visualization in 20 cases (27.8%), while abnormal ureteral findings were noted in 18 cases (25.0%). 9. Of 60 operated cases, 44 cases were managed with nephroureterectomy, 8 cases with nephroureterectomy and reconstructive surgery and 5 cases with nephroureterectomy and contralateral urinary diversion, but 3 cases with diversion only.
