this study suggests, based upon previous pharmacological studies, that the decrease of the serum calcium level in shr causes a decrease in central, calcium-calmodulin-dependent dopamine synthesis and a subsequent low level of dopamine in the brain that produces an increase in blood pressure through functions of cerebral dopaminergic neurons and peripheral sympathetic nerves. |

because vmn and preoptic dopaminergic activities were depressed in small litter vs. control litter rats but the percentage of body fat was unchanged, this decreased dopamine metabolism is probably not causal to the obesity development. |

the authors suggest that estrogenic and androgenic receptors of adenohypophysis and dopaminergic systems of the brain contribute to the mechanism of regulation of the second phase of fsh increased secretion observed in the early morning hours of the estrus stage, the dopamine effect on fsh release being mediated via estradiol receptors. |
