In vivo pharmacological characterization of alpha adrenergic receptors in sheep myometrium and their physiological meaning.

Utero-cervical responsiveness to alpha-adrenergic receptor stimulation was electromyographically evaluated in vivo in adult ovariectomized ewes. Spontaneous motility and drug-induced changes were quantified with a microcomputer. Our results suggested that the two activity patterns previously described on the ovine genital tract could be respectively… CONTINUE READING
