The Role of Interleukin-33 in Pathogenesis of Bronchial Asthma. New Experimental Data.

Interleukin-33 (IL-33) belongs to the IL-1 cytokine family and plays an important role in modulating immune system by inducing Th2 immune response via the ST2 membrane receptor. Epithelial cells are the major producers of IL-33. However, IL-33 is also secreted by other cells, e.

[Phospholipase D: its role in metabolism processes and disease development].

Phospholipase D (PLD) is one of the key enzymes that catalyzes the hydrolysis of cell membrane phospholipids. In this review current knowledge about six human PLD isoforms, their structure and role in physiological and pathological processes is summarized. Comparative analysis of PLD isoforms structure is presented.

[Biologically active substances of cornelian cherry fruits (Cornus mas L.)].

10 samples of fresh-frozen cornelian cherry fruits (Cornus mas L.), collected in the Tambov and the Caucasus regions, were investigated for the total amount and composition of the main biologically active substances (BAS): anthocyanins (AC), proanthocyanidins (OPC), dihydroxycinnamic acids (DHCA), iridoids, organic acids, mono- and disaccharides and antiradical activity in the DPPH-test in vitro. Total phenolics content determined by Folin-Ciocalteu method, was 150-400 mg/100 g fresh fruit weight.

[The dissolution test in biorelevant media as a prognostic tool for modeling of drug behavior in vivo].

The review deals with the modern tool for modeling of drug behavior in vivo, - the dissolution test in biorelevant media, imitating gastrointestinal fluids. The formulations and preparation methods of fasted state simulation intestinal fluid, FaSSIF and fed state simulation intestinal fluid, FeSSIF, are defined. In addition, the dissolution characteristics of APIs from different BCS classes in biorelevant media are described.

[The influence of vitamin B group on monooxygenase activity of cytochrome P450 3A4: pharmacokinetics and electro analysis of catalytic properties].

It was shown that vitamin B group permit to shorten the longitude of diclofenak therapy and to reduce the daytime dose of this drug. All three schemes of diclofenac treatment - only diclofenac, diclofenac plus 2 tablets of Gitagamp (mixture of vitamin B group), and diclofenac plus 4 tablets of Gitagamp--gave maximum value of diclofenal in blood through 1 hour after treatment. In the case of diclofenak treatment without vitamins Cmax corresponds to 1137.
