Effects of Fasting and Aproteic Diet on Prolactin Regulation in the Rat
by Osvaldo Ponzo, Dora Rondina, Silvina Nacht, Berta Szwarcfarb, Silvia Carbone, Jaime Moguilevsky & Pablo Scacchi


Abstract:

Both fasting (F) and Aproteic diet (Ap) produced a significant reduction in serum Prolactin (PR) in male rats. The refeeding with control diet (20% of protein), increased serum PR levels over the control ranges. The PR concentration in the adenohypophysis tissue was also decreased significantly. The hypothalamic dopamine in F and Ap group was significantly decreased. Sulpiride test increased PR level in Ap and Co groups. The relative increment was higher in the Ap group.
