В статье рассмотрены особенности фармакодинамики интравагинального и перорального путей лечения препаратами микронизированного прогестерона. Представлены результаты использования препарата микронизированного прогестерона Прогинорм Геста на этапе прегравидарной подготовки женщин с аденомиозом. Обосновано интравагинальное применение микронизированного прогестерона Прогинорм Геста с целью профилактики и лечения ранней потери беременности у женщин с аденомиозом. Установлено, что назначение Прогинорм Геста в первом триместре беременности предупреждает потерю беременности у женщин с аденомиозом, а также является эффективным средством лечения угрозы аборта. The article discusses the features of the pharmacodynamics of intravaginal and oral treatment with micronized progesterone drugs. The results of the use of micronized progesterone preparations Proginorm Gesta at the stage of pregravid preparation of women with adenomyosis are presented. The intravaginal use of micronized progesterone Proginorm Gesta is substantiated for the prevention and treatment of early pregnancy loss in women with adenomyosis. It has been established that the appointment of Proginorm Gesta in the first trimester of pregnancy prevents pregnancy loss in women with adenomyosis, and is also an effective treatment for the threat of abortion.

A new paste is proposed for frosting glass surfaces. The action of the paste is based on the physical-chemical process of surface chemical ion exchange. The paste does not contain hydrofluoric acid or its derivatives. The frosting process occurs at 300°C and differs substantially from the existing frosting processes -chemical etching and sandblasting. The morphology of the surface layer of the frosted glass is characterized by a system of microblocks (linear dimensions 50 -150 mm) and microcracks (width 100 -200 nm). The microblocks have even faces and a smooth frontal surface. The surface morphology of the glass is the same after frosting and subsequent deposition of a metal by chemical reduction.It is well-known that an important factor in the deposition of organic or inorganic coatings on a glass surface is the adhesion power of the glass, which acts as a substrate. Modification of the structure of the surface layer of glass by, specifically, frosting can change the surface roughness substantially and, in consequence, increase the adhesion power of the glass as a substrate per unit area of the geometric surface.Sandblasting with solid abrasive particles and chemical etching of a glass surface by solutions containing hydrofluoric acid or its derivatives are now widely used for frosting glass.A new method of frosting glass is applying a paste (RF Patent No. 2238919) [1, 2], which does not contain hydrofluoric acid or its derivatives and acts on the basis of surface ion exchange processes [3,4]. The present article gives the results of a comparative investigation, by the method of electron scanning microscopy, of the morphological structural properties of the surface layer of glass modified by sandblasting, chemical etching, and treatment with the new frosting paste (NFP) which contains no hydrofluoric acid. The structure of the surface layer of glass after frosting by chemical etching and by using the NFP followed by deposition of a thin layer of silver by chemical reduction was also investigated.Samples of sodium-calcium-silicate glass (GOST 111-2001) were used. Chemical etching was performed by fluorine-containing paste for frosting glass, prepared following the recommendations presented in USSR Inventor's Certificate No. 948926A. The duration of the chemical etching of the glass samples was 5 -10 min.The glass surface modification process NFP consisted of the following stages [1, 2]: degreasing the surface and washing with warm flowing water;depositing a layer of paste on the glass surface with an appropriate tool using a stencil consisting of a film manufactured by the ORACAL Company and prepared by plotter cutting, or using a silkscreen form;removing the stencil, if it was used at the preceding stage;heat-treatment of the glass sample at approximately 300°C for 15 -20 min;removing the dry layer of paste by washing in warm flowing water.A doctor was used to deposit the paste layer on the surface of the glass. The thickness of the paste layer deposited on the glass when using a stencil consisting of an ORACAL...
