- 体内研究
Vanillylmandelic acid (intra-arterial injection over 1 min; 1, 10 and 100 mg/kg; the 60 min-observation period) produces a significant difference between vanillylmandelic acid groups and controls. Vanillylmandelic acid decreases the heart rate by 17.5%, 17.9% and 18.9% after 1, 10 and 100 mg/kg, respectively. Mean blood pressure is decreased by 13.5% in control animals as compared to 37%, 23% and 26% after 1, 10 and 100 mg/kg, respectively, in wistar rats.
