To investigate the anti-hyperprolactinemic effect of Ficus pumila
Linn. extract (FPLE) in rats.
Hyperprolactinemic rats were generated by subcutaneous injection of metoclopramide
dihydrochloride (50 mg/kg). A high dose (800 mg/kg), moderate dose (400 mg/kg), or low dose (200
mg/kg) of FPLE was administered into the stomach of hyperprolactinemic rats for 30 days, after which
serum sex hormones and pituitary prolactin-positive cell number and mRNA expression were measured.
FPLE had a significant effect on measures of hyperprolactinemia. Compared with
hyperprolactinemic rats without FPLE treatment, hyperprolactinemic rats that received a high dose of
FPLE showed altered serum estradiol, progesterone, prolactin, follicle-stimulating hormone, and
luteinizing hormone levels (p < 0.05), as well as decreased pituitary prolactin-positive cell number (p <
0.05) and mRNA expression (p < 0.05).
FPLE can potentially be used as an anti-hyperprolactinemia treatment but further studies
are required to ascertain its suitability.
