title: Effect of enkephalins in the presence of the antibiotic bacitracin in the longitudinal muscle strip preparation from guinea-pig ileum.
abstract: The antibiotic bacitracin (5 x 10(-5) -4 x 10(-4) M) increase the inhibition of the contractile response caused by both enkephalin release and direct application of Met-enkephalin 5 x 10(-7) M in the longitudinal muscle strip preparation from guinea-pig ileum. This effect is attributed to an inhibition of enkephalin degrading peptidases by bacitracin.
