Reactivity of the epithelial cells of the bovine oviduct in vitro on the exogenic gonadotropic and steroid hormones. Part I: The effect of gonadotropic and steroid hormones on the amount of lipids and activity of dehydrogenases.

Effects of 17 beta-estradiol, testosterone, progesterone, luteinizing hormone and a combined effect of estradiol and progesterone on the epithelial cells of the bovine oviduct cultured in vitro were investigated. It was found that these cells may transform under the effect of hormones. The effect of the applied hormones on the amount of lipids and activity of the dehydrogenases delta 5 3 beta-OH-SDH and G6P-DH was evident. Cells in vitro most intensely reacted on testosterone and estradiol: these hormones caused an increase of lipids and of enzymatic activity. The cells also reacted to progesterone and the luteinizing hormone which in turn decreased both activity and accumulation of lipids in cells.
