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.

The exact analysis of urinary stones is very important to the study of the etiology of stone formation, prevention of recurrence and medical treatment. We Have analyzed 260 urinary stones obtained form 260 patients by X-ray diffraction method and studied the relationships of stone compositions to stone sites, patient age, sex and stone weight. The following results were obtained : 1. In this study 7 crystalline compositions of urinary stones were observed : Calcium oxalate monohydrate, Calcium oxalate dihydrate, Magnesium ammonium phosphate, Calcium magnesium phosphate, calcium phosphate, Uric acid and cystine. 2. Single composition stones were slightly more in number than mixed composition stones. Of 260 stones, 192(74%) were mainly composed of calcium oxalate, 38(14.4%) of magnesium ammonium phosphate, 19(7.3%) of calcium oxalate and calcium phosphate, 10(3.9%) of uric acid and 1(0.4%) of cystine. 3. Calcium oxalate stones was the most common of all the urinary stones and that comprised 80.7%(96) of all renal stones, 93.5%(86) of all ureteral stones, 46.2%(18) of all bladder stones and 100%(9) of all urethral stones. 4. Of 181 patients, ranged 30 to 59 years old who comprised 70% of all patients, 149(82.3 % of 181 patients) had calcium oxalate stones. 5. The ratio of the occurrence of magnesium ammonium phosphate to all renal or bladder stones from females was higher than that from males. 6 Of 27 stones weighed more than 10gm, 14(52%) were mainly composed of magnesium ammonium phosphate, and 10(37%) of calcium oxalate.

Male genital traumas on penis, scrotum and testis primarily result from external violences including motor vehicle accidents, industrial mishaps, gunshots, laceration, rights and sexual intercourse. The loss or function in this system may be not vital but the quality of patient`s life be deleterious if they are not properly managed. So, we reviewed 98 patients with male genital tract trauma in the view point or early and delayed treatment, and concluded that early diagnosis and judicious treatment gave patients the best chances of recovering urinary and genital function after genital trauma.
