Tibolone is a synthetic steroid with estrogenic effects on brain, vagina, and bone without stimulating the endometrium. During tibolone treatment, it is thought that the progestagenic properties of tibolone stimulate cell differentiation, which effectively counterbalances the growth-stimulating effects of the estrogenic properties of tibolone. The objective(More)
ADJUVANTS are considered to play an important role in directing the isotype and amount of antibodies produced upon immunization by conducting the development of either Th-1 or Th-2 cells upon T-cell stimulation. This is based on the different cytokine production patterns that were observed after in vitro resttmulation of T cells isolated from mice immunized(More)
In this study, we assessed the effects of tibolone and its metabolites on the production of a progesterone sensitive parameter, prolactin, in human endometrium stroma cells in vitro. In addition, the metabolism of the compounds by isolated stromal and epithelial cells was evaluated. The reference compounds, progesterone, Org 2058, and DHT all induced(More)
In postmenopausal women, tibolone shows clear tissue differences in its stimulatory effects on the vagina and uterus. In rats, however, it has stimulatory effects on both tissues, with a different, more estrogenic, effect on the uterus than in humans. This may be due to differences in local metabolism. Therefore, in the present study, the metabolism of(More)
