title: [Significance of estradiol in the development of fibrosis in systemic scleroderma (bases of sexual predisposition to the disease)].
abstract: The influence of estradiol (E2) was studied on the production of type III procollagen by cultivated fibroblasts from the skin of healthy donors and SSD patients. It has been found that when in the norm E2 (concentration 10(-8) and 10(-7) M) inhibits the production of type III procollagen. In SSD the hormone's effect is not found. Here the quantity of E2 receptors in cells from SSD patients is 1.96 time lower than the norm. The resulted data testify to the fact that the decrease of E2 receptors in fibroblasts from SSD patients may be one of the factors contributing to the increase in the functional activity of cells and to the fibrosis progression.
