[Functional and morphological identification of FSH- and LH-producing cells in the pituitary gland]

The identification of pituitary FSH and LH cells in states of pharmacological treatment influencing the pituitary FSH and LH production was performed by histological staining at the isoelectric points of these hormones in the cat. The intensity of the stained material in the hormone-producing cells was determined by a microphotometric technique. As a physiological control, the FSH and LH levels in blood were measured by a radioimmunoassay.
