Abstract
The review presents the geographical distribution, botanical description, chemical composition, information about the use in medicine and the study of the pharmacological activity of the representatives of the genus Genista L. It is shown that the plants of the genus are widely distributed on the territory of the Russian Federation, however, it is rather difficult to systematize the plants of the genus of interest on the basis of morphological characters, since they have an extensive habitat and, accordingly, the morphological characteristics of one species vary greatly within the range. Plants of the genus have a rich composition of biologically active substances. At the same time, an analysis of literature data on products of the secondary metabolism of species of the genus Genista revealed an uneven degree of their knowledge. Infusions and decoctions from the grass of Genista are used in folk medicine as a diuretic, choleretic and laxative, and an analysis of literary sources showed that plants of the genus are promising in various pathologies. The authors of the review showed the need for a complex morphological, anatomical, phytochemical, and molecular genetic study of plants of the genus Genista to clarify the taxonomy and introduction into medical practice.

Abstract
The paper presents an overview of the structure and functions of caspase group enzymes. The main stages and ways of development of programmed cell death - apoptosis were demonstrated. The mechanisms of inhibition and activation of caspasesand their role in cell apoptosis are demonstrated. The different stages of caspase activation in the body are still insufficiently studied. At present, the structure, properties, key points of the functioning and regulation of caspases in the body have been studied in detail, but at the molecular and cellular levels it is not enough to directly regulate their activity. Modern studies of the effect of artificially created substances of different nature on these enzymes, in turn, open up prospects for further search for methods of their regulation, which in turn would allow using the knowledge gained in the treatment of oncological, autoimmune and neurodegenerative diseases.

Abstract
The risks for the functional characteristics of Salbutamol pressurized metered dose inhaler (pMDI), such as the uniformity of delivered dose, the distribution of salbutamol particles at the stages of the Andersen impactor (apparatus D), and the respirable fraction, were studied and identified. It is shown that these risks can be associated with the solubility of salbutamol sulfate (SS), the formulation of pMDI, the water content in the SS and ethanol, as well as the particle size distribution of SS. A relationship is shown between the particle size distribution of the SS, the rate of their sedimentation and the performance characteristics of the preparation. The properties of SS crystals are investigated and the possibility of enantiomers presence is shown. The risks associated with the production process, the materials of the primary packaging and the correctness of the quality control procedures are discussed. It is shown that the use of containers made of aluminum alloy EN AW-5052-0 without internal coating does not pose the risk of the release of elemental impurities into the preparation. Unjustified replacement of actuators may pose a risk to the performance characteristics of Salbutamol pMDI and in vitro equivalence as compared with the reference medicinal product.

Abstract
Rosaceae plants are widely used in medical practice. Many species of this family, including representatives of the genus Meadowsweet, are used in folk medicine. Little-known representatives of the genus are the Meadowsweet kamtschatica - Filipendula kamtschatica (Pall.) Maxim. and the Meadowsweet palmata - Filipendula palmata (Pall.) Maxim. Filipendula kamtschatica has a Pacific type of range, is endemic to the Russian Far East. Filipendula palmata is widely distributed in Eastern Siberia and the Far East. Both species are easily cultivated. In the aerial parts of plants contain various groups of biologically active substances: compounds of polyphenolic nature (tannins, flavonoids, phenolic acids); essential oils, triterpene compounds, vitamins, amino acids, polysaccharides. Filipendula palmata use in folk medicine as an anti-inflammatory, diaphoretic, diuretic, anthelmintic, astringent and restorative means, in the treatment of rheumatism, arterial hypertension, nervous disorders, upper respiratory tract and epilepsy. Filipendula kamtschatica has hemostatic, anti-inflammatory, analgetic, astringent, diuretic and antiscorbutic effects. Data on the morphological and anatomical study of the leaves of these species of the meadowsweet are absent in the literature. The purpose of this work is to develop criteria for the authenticity of the leaves of the Meadowsweet palmate and Meadowsweet kamchatika such as morphological and anatomical signs. The objects of the study were dried leaves of Filipendula kamchatika harvested in St. Petersburg and Leningrad region from cultivated plants in 2011-2012, and leaves of a Filipendula palmata collected in 2014 in the Republic of Buryatia. The appearance of the leaves was studied using a binocular magnifier; their anatomical structure was determined by preparing temporary preparations using a microscope «Micromed-1 VAR 1-20». The main macroscopic signs of the leaves of the two species of the Filipendula have been determined. In surface preparations, the epidermis of the upper side of the leaves of the Meadowsweet kamchatika and the Meadowsweet palmate morphologically differs from the epidermis of the lower side. The upper epidermis consists of polygonal cells with straight walls, in the Filipendula kamchatika places with a clear-shaped thickening. The epidermis of the lower side consists of cells with winding side walls. Stomata anamazing type. The general anatomical signs of the leaves are simple, thick-walled unicellular hairs with an expanded base and druses of calcium oxalate crystals in the mesophyll. For the leaves of Filipendula camtschatica are characterized by thin-walled capitate hairs, with 1-2-cell oval head on 2-3-(6)-cell stem. In the leaves of Filipendula palmata there are thin-walled unicellular hairs of different lengths, secretory cells, idioblasts with yellow-brown content were found in the mesophyll of the leaf.
