ABSTRACT
Aqueous extracts of Casimiroa edulis leaves injected intravenously to 20 normal Sprague-Dawley rats produced a rapid and transitory increase in blood pressure. The amplitude of the blood pressure rise was dose dependent. The increase was statistically significant (p < or = 0.01) at a concentration of 220 mOsm/l, and was associated with a significant heart rate decrease (p < or = 0.01) probably secondary to barorreceptor stimuli. The application of 130 mOsm/l of the extract did not produce a significant increase in blood pressure, which was followed by a rapid pressure normalization. The slight increase in cardiac rate during the pressure lift was probably due to sympathetic stimuli
