    New data on the phylogeny of four rare and endemic species of RanunculusL. (sect. RanunculastrumDC.) of western Pamir-Alai, one of which is new to science, have been obtained. Ranunculus tojibaeviisp. nov., from the Baysuntau Mountains, Western Hissar Range of Uzbekistan, is described. The new species is closely related to R. botschantzeviiOvcz., R. convexiusculusKovalevsk. and R. alpigenusKom., but differs in the blade of the radical leaves, which is rounded-reniform, segments 3–5-dissected, each 2–5-partite with elongated, rounded apical lobes. A phylogenetic analysis, using both the nuclear ribosomal internal transcribed spacer (ITS) and cpDNA (matK,rbcL,trnL-trnF), was informative in placing R. tojibaevii in context with its most closely-related species. Discussion on the geographic distribution, updated identification key, a detailed description, insights about its habitat and illustrations are provided

    Summary. Morphological characteristics of gastric mucosa in patients with asthma of different severity with regard to corticosteroid therapy were described in this article. The aim of this study was to substantiate optimized standards of asthma treatment. Clinical and morphological investigations were conducted at the city clinical hospital β„– 31. We investigated all structural components of the gastric mucosa in biopsy specimens with light binocular microscopy and performed morphometric study of inflammatory infiltrates. As a result, several signs of protective effect of inhaled corticosteroids on gastric mucosa were found. We did not obtain any results that could confirm the key role of glucocorticosteroids in occurrence of gastrointestinal erosions in asthma patients. Therefore, prevention of erosive gastritis and other inflammatory gastrointestinal diseases in asthma patients should consider other risk factors besides glucocorticosteroid therapy and cover all stages of asthma.РСзюмС.
