Prenatal and postnatal vanadium exposure in rats: effect on vasomotor reactivity development of pups.
The study has been carried out on albino rats pre and/or postnatally exposed to vanadate (1 and 10 mg/dl). In pups pre- and postnatal or postnatal vanadate exposure significantly decreased on the 30th and 60th day of age the pressor response to 1-noradrenaline, and increased the pressor response to sinus-carotid baroreceptor stimulation and the hypotensive responses to 1-isoprenaline and acetylcholine. The effects were observed at vanadate doses that did not interfere with gestation, maternal and pup body weight, maternal systolic arterial blood pressure during pregnancy, and pup systolic arterial blood pressure. These doses have not determined any macroscopic teratogenic effects.
