Abstract
The effect of chronic lead treatment on pituitary dopamine (DA) D2 receptors was studied by measuring (-)sulpiride-displaceable [3H]spiroperidol-binding and DA-inhibited adenylate cyclase. Receptor number was reduced in lead-exposed animals and bromocriptine was less able to inhibit cyclase activity in pituitary homogenates. In addition, the capacity of DA to inhibit the VIP-stimulated cAMP formation was decreased.
