Inhibition by 2-bromo-alpha-ergocriptine and tamoxifen of the growth of an estrogen-dependent transplantable pituitary tumor (MtT/F84) in F344 rats.

A new transplantable pituitary tumor, designated MtT/F84, was induced in estrogenized female F344 rats and has been serially passaged in 17 beta-estradiol-treated females.
