Summary: | The effect of adrenalin, noradrenalin, or isoprenaline, alone or in the presence of an
alpha (dibenzyline) or beta (dichlorisoproterenol) adrenergic blocking drugs, on isolated
uterus from a viviparous lizard ( Liolaemus gravenhorti ) and an ovoviviparous one ( Liolaemus tenuis ), showed that both alpha and beta adrenergic receptors are present in the uterus of
both species.
Adrenalin and noradrenalin induced contraction, sometimes followed by relaxation,
and this effect was blocked by dibenzyline. Isoprenaline always induced relaxation which was
blocked by dichlorisoproterenol. These effects, with small differences, were observed in the
uterus of both species, whether pregnant or not, although the sensitivity to the stimulation of
both receptors appeared highest in the pregnant uterus of L. gravenhorti . |
