Stubies on γ-amino-β-hydroxybutyric acid I. Influences of γ-amino-β-hydroxybutyric acid on the blood pressure, respiration and body temperature

Abstract

The biological specificity of GABOB on the blood pressure, respiration and body temperature was observed in dogs. The results show that GABOB has the similar action as GABA on the lowering of blood pressure as shown by subcutaneous, intravenous or intrathecal injection, but loses its action on the respiration. The specificity of GABOB action on the blood pressure is seen in the initiation of the effect at which the transient rise in pressure can be seen, the like of which can never be seen in the case of GABA injection. The lowering mechanism of GABOB on blood pressure should be the central one as the intrathecal injection is most effective comparing with those of intravenous and subcutaneous injection.</p
