The aim of the present study was to determine the respective role of 1,25-dihydroxyvitamin D3 on vaginal epithelium and 1,25-dihydroxyvitamin D3 receptor expression in ovariectomized rats and vitamin D3 treated rats. Bilateral ovariectomies were performed in 20 mature, non-pregnant Wistar female rats. All the animals were divided into 2 groups consisting of(More)
Staphylococcin 1580 killed cells of Staphylococcus aureus Oxford 209P. At low concentrations of staphylococcin the decrease of the viable count as well as the efflux of rubidium ions, and the inhibition of the uptake of amino acids were linearly related to the amount of the bacteriocin used. The killing action could not be reversed by treatment with(More)
Colicin A and staphylococcin 1580 inhibit the amino acid transport by cells of Escherichia coil and Staphylococcus aureus, respectively (Nagel de Zwaig, 1969; Jetten and Vogels, 1972). This transport is coupled to the electron transport chain via specific dehydrogenases. Colicin A inhibited the uptake of ~4C-glutamic acid into membrane vesicles of E. coil(More)
