[Result] 3.5 mg/kg, bw anisodamine dosage was injected before radiography, 10 minutes after radiography was the best time to take photo, and the development of experimental dog＇s bilateral renal contour, renal pelvis and front segment of ureter was basically clear.

[ Condmion] Vitamin K3, as a kind of hypotonic medicine used in pet clinical （ IVP）, had characteristics of safety, low dosage and better practical radiography effect, was obviously better than anisodamine, and could be properly promoted in pet clinical （IVP）.展开更多
