the present study demonstrates that chronic elevations in serum prolactin , to greater than 2,000 ng/ml , induced by the prolactin secreting mttw15 tumor , decreased da concentrations by 47 % in the median eminence-arcuate nucleus ( me-arc ) region , by 43 % in the medial basal hypothalamus ( mbh ) and 14 % in the preoptic area-anterior hypothalamic region ( poa-ah ) without influencing the norepinephrine levels in these regions .
