The interaction of androgens and prolactin, the major factors regulating the male accessory sex organs, on the specific activity of seminal vesicular enzymes of the pyruvate/malate cycle were studied in castrated mature monkeys. Castration decreased the activity of these enzymes, including NADP+
isocitrate dehydrogenase
, ATP citrate lyase, malate dehydrogenase, malic enzyme and fatty acid synthase. Testosterone propionate (TP)/dihydrotestosterone given as replacement to castrates increased the activity of all these enzymes, except for malate dehydrogenase.
Prolactin
restored normal activity of ATP citrate lyase, malic enzyme and fatty acid synthase but not of
isocitrate dehydrogenase
and malate dehydrogenase (MDH).
Prolactin
had a specific control over MDH. Moreover, when prolactin was combined with androgens a further stimulatory influence was observed on fatty acid synthase activity. In order to prove the direct influence of prolactin on enzymes of the pyruvate/malate cycle, bromocriptine was administered and this inhibited all of the enzymes. Thus prolactin was found to have a direct, as well as a synergistic, action with androgens on enzymes of the pyruvate/malate cycle in the seminal vesicles of monkeys.

Prolactin
(
PRL
) has an important role in the regulation of water and electrolyte homeostasis in teleosts. The present study was designed to evaluate the role of
PRL
and GH on malic enzyme (ME), glucose-6-phosphate dehydrogenase (G6PDH) and
isocitrate dehydrogenase
(ICDH) in Anabas testudineus. Ovine prolactin significantly inhibited ME, G6PDH and ICDH activities when administered in vivo compared to vehicle treated controls. In vivo administration of
PRL
reversed the action of bromocryptine on enzyme activities. Ovine growth hormone in vivo also modified the effect of bromocryptine but not to the level of prolactin. Combined action of PRL+GH in vivo was most effective in keeping the enzyme activities at normal level after bromocryptine treatment.
Prolactin
in vitro also reversed the action of bromocryptine on enzyme activities, while GH in vitro failed to do so. Hence, prolactin seems to have an inhibitory effect on lipid metabolism in this teleost. Combined action of PRL+GH is more prominent in in vivo conditions at low
PRL
levels. Dopaminergic pathways may be involved in the control of prolactin and to some extent on growth hormone secretion.
