Morphological, histochemical and immunohistochemical studies of polar fox kidney.

The aim of the present study was to evaluate the morphology and intermediate filaments cytokeratin, desmin and vimentin expression in the kidneys of the polar fox (Alopex lagopus). Routine morphological, histochemical and immunohistochemical techniques of examinations of the kidneys of adult male and female polar foxes were used. We found different localizations and different levels of immunoexpression of cytokeratin in epithelia of calyxes, distal tubules and Henle's loops, and also in endothelial cells.

Morphological and immunohistochemical comparison of three rat prostate lobes (lateral, dorsal and ventral) in experimental hyperprolactinemia.

Unlabelled: The prolactin plays an important role in the regulation of growth and differentiation of prostate gland besides androgens. The goal of this study was to reveal the influence of elevated prolactin concentration on epithelial cells of prostate. We compared the morphology of epithelial cells of prostate dorsal, lateral and ventral lobes and expression of androgen receptors in these cells in rats with hyperprolactinemia and in control rats.

[Prolactin receptors in the prostate].

Following article describes available information presenting current knowledge on prolactin receptors expression and prolactin actions in the prostate gland. Prostate is strongly androgen dependent gland, however poseses receptors for other ligands including hypophyseal hormones and growth factors. More over prolactin is also locally produced and secreted acting also in paracrine way on the prostate.

Morphology of the epithelial cells and expression of androgen receptor in rat prostate dorsal lobe in experimental hyperprolactinemia.

The effect of hyperprolactinemia on the prostate has not been well investigated. Since androgens play an important role in prostate development, growth and function, the goal of the present study was to estimate the influence of hyperprolactinemia on expression of the androgen receptor (AR) in rat epithelial cells of prostate dorsal lobe and on morphology of these cells. Studies were performed on sexually mature male Wistar rats.

The expression of androgen receptors in the epithelial cells of the rat prostate lateral lobe in experimental hyperprolactinaemia: a morphological and immunohistochemical study.

The effect of hyperprolactinaemia on the prostate has still not been fully elucidated. The aim of the study was to estimate the influence of hyperprolactinaemia on expression of the androgen receptor (AR) in rat epithelial cells of the prostate lateral lobe and on the morphology of these cells. Studies were performed on sexually mature male Wistar rats.
