Résumé / Abstract

Extracts squeezed from Agaricus blazei fruits-body (ABFE) contain 7-aminobutyric acid (GABA), which expect hypotensive effects in hypertensive persons. We investigated hypotensive effects of A-extract in a double blind trial, 134 adults (averaged 48 years old) with high-normal blood pressure or mild hypertension. The amount of GABA in A-extract prepared 4 groups, which contain placebo (A group), 20mg GABA/50mL ABFE (B group), 40mg GABA/50mL ABFE (C group) and 70mg GABA/50mL ABFE (D group). All subjects were administrated once dairy for 8weeks. The results revealed that C group significantly decreased diastolic blood pressure (DBP) at 8 weeks in comparison with A group. C group significantly decreased systolic blood pressure (SBP) at 6 and 8 weeks and DBP at from 4 to 8 weeks in comparison with A group. D group significantly decreased systolic blood pressure (SBP) at 6 and 8 weeks and DBP at from 2 to 8 weeks in comparison with A group. B and D group increased blood pressure after finished administration of ABFE at once. Furthermore, subjective symptom, objective symptom, and blood examination were not observed in all subjects. These results of this study suggested that ABFE has hypotensive effects in adults with high-normal and mild hypertension, and optimal concentration of GABA is 40mg GABA/50mL ABFE.
