title: Inhibitory substance (substance I) in rat liver of dopamine-beta-hydroxylase and its effect on the rat blood pressure.
abstract: In a series of experiments undertaken to investigate the naturally occurring inhibitors of dopamine-beta-hydroxylase, we extracted some active substance from rat liver. This substance was named "substance I" because of its inhibitory effect on the dopamine-beta-hydroxylase. Substance I had some hypotensive effect on the rat blood pressure.
