title: Interaction of perphenazine and an ergoline derivative on oestrogen-induced adenohypophyseal growth.
abstract: Male and female rats were injected twice a week for three weeks with doses of 1 mg oestradiol benzoate (OE), were given perphenazine (P, 2 mg/rat/day) or the ergoline derivative D-6-methyl-8-ergoline-(I)-yl acetic acid amide (Deprenon SPOFA, D, 200 microng/rat/day) in their food or were treated with various combinations of all three factors. OE-induced adenohypophyseal growth was inhibited by D, but the inhibitory effect of D was completely suppressed by P. D also inhibited the OE-induced increase in the thyroxine-binding capacity of the adenohypophyseal proteins, but this inhibition was not suppressed by the simultaneous administration of P. The administration of OE was followed by elevation of the serum ceruloplasmin level, which was not inhibited by P or D, either alone or combined. Ovarian weight rose markedly after D and the increase was inhibited by the simultaneous administration of either OE or P.
