Bladder top An incision was made, and force-yure (Hibiki polyethylene tube size 8, made of kunyine earth) was inserted to conduct urine. A tube (INTRAMEDIC PE-60, Becton Die kinson and Company, Sparks, MD, USA) fitted with an artificial calculus (spherical glass beads BZ—06, manufactured by AZ One Corporation, with a diameter of 0.6 to 0.8 mm) is placed on the dorsal side of the left kidney. A rat ureter stone model was created by inserting into the renal pelvis from the head, introducing glass beads into the upper ureter, and fixing it to the dorsal position on a heat-retaining fixture set at 37 ° C.
- urethane 1.0-1.2 g /
- test substance was administered into the duodenum. Starting from the stagnant site, the distance traveled by the glass beads 3 hours after administration of the test substance was measured.
