In this report the intraluminal pressure of the vas deferens was measured in vivo in male cross-bred dogs. The measurement of the pressure elucidated that the vas deferens repeated autonomic contraction. This contraction was not the so-called peristalsis but the entire portion of the vas deferens contracted simultaneously. Stimulation of the hypogastric(More)
The effects of psychotropic drugs on ejaculation in dogs and on brain monoamines in dogs and rats were investigated. The results obtained in this study indicate that ejaculation is activated by the dopaminergic system in the brain, and that dopamine in the anterior hypothalamus is closely related to the occurrence of ejaculation.
A 62-year-old male with left ureteritis cystica was reported. Extracorporeal shock wave lithotripsy (ESWL) was performed for his left renal stone 14 and 17 months earlier. However, small fragments remained in the lower calyx and pyuria, microhematuria and bacteriuria continued. Drip infusion pyelography (DIP) showed a small filling defect of the left(More)
This study deals with the role of the stone matrix substance in formation of urinary stones. A series of coagulation experiments were conducted by determining the sedimentation rate of calcium carbonate suspension with respect to the following substances: sodium alginate, stone matrix substance, bovine albumin and chondroitin sulfate C, these were each(More)
The effects of 5-HTP and pCPA on manually induced ejaculation in dogs and on brain monoamines in dogs and rats were investigated. From the results obtained in this study it was concluded that the serotonergic system in the brain is the mechanism which inhibits the occurrence of ejaculation. Considered together with the results obtained in our previous(More)
The present study was undertaken to determine if urinary protein can produce urinary stones and what types of protein have such an effect. Normal human serum was fractionated first with ammonium sulfate and then with DEAE-cellulose. The stone-forming action of each fraction was estimated by calculating their ability to alter the sedimentation rate and(More)
BACKGROUND Pulmonary resection for metastatic renal cell carcinoma were studied to assess the indication of surgical management. METHODS Between January, 1981 and December 1994, 17 consecutive patients (14 men and 3 women) underwent complete pulmonary resection for metastatic renal carcinoma. Median age was 61 years (range, 45 to 73 years). Eleven were(More)
The effects of autonomic drugs on closure of the internal urethral orifice during ejaculation were investigated in dogs. The closure of the internal urethral orifice was induced by the electric stimulation of the lateral fibers of the lower mesenteric plexus. The closing state of the orifice was measured with a latex balloon inserted into the orifice. The(More)
