Interaction between phenylephrine and prostaglandins E1 and F1 alpha on the contractile responses of vascular muscle.

Prostaglandins (PGs) E1 or F1 alpha (1.4--8.4 x 10(-8) M) contracted strips of rabbit aorta and increased the contractions produced by 1--6 x 10(-7) M phenylephrine (PE).

Influence of prostaglandins E1 and F1alpha on K-induced responses in vascular smooth muscle.

The effects of PGE1 and PGF1alpha (1.4-8.4 X 10(-8)M) were studied on contractures induced by 10--60 mM KCl in the isolated rabbit aorta.
