Antimicrobial and Cell-Friendly Properties of Cobalt and Nickel-Doped Tricalcium Phosphate Ceramics.

β-Tricalcium phosphate (β-TCP) is widely used as bone implant material. It has been observed that doping the β-TCP structure with certain cations can help in combating bacteria and pathogenic microorganisms. Previous literature investigations have focused on tricalcium phosphate structures with silver, copper, zinc, and iron cations.

Strontium Substituted β-Tricalcium Phosphate Ceramics: Physiochemical Properties and Cytocompatibility.

Sr-substituted β-tricalcium phosphate (β-TCP) powders were synthesized using the mechano-chemical activation method with subsequent pressing and sintering to obtain ceramics. The concentration of Sr in the samples was 0 (non-substituted TCP, as a reference), 3.33 (0.

Comparative analysis of the dispersion quality of oxymetazoline nasal sprays.

Metered-dose nasal sprays (MDNS) are the most widely used for treating rhinitis. Medicinal preparations in the pharmaceutical market vary in their characteristics. To identify the most effective drug, it is necessary to compare the preparations regarding various parameters.

[Toothpastes of the «Mexidol dent» line - parapharmaceuticals with stable antioxidative activity].

The Aim Of The Study: Was to assess the stability of antioxidative activity of the active compound 2-ethyl-6-methylpiridine-3-ol succinate of toothpastes of the «Mexidol dent» line.

Materials And Methods: The study involved toothpastes of «MEXIDOL dent» line: MEXIDOL dent Aktiv MEXIDOL dent Complex, MEXIDOL dent Sensitive, MEXIDOL dent Fito, MEXIDOL dent Teens, MEXIDOL dent Professional White. Features of 2-ethyl-6-methylpiridine-3-ol succinate («MEXIDOL») determined the choice of potentiometric titration method for the assessment of the stability of antioxidative activity.

[Comparative analysis of Kameton spraying parameters of different manufacturers].

Purpose: Based on a comparative analysis of the key dispersion parametries of spray-aerosol forms of drugs Kameton from different manufacturers the most effective drug in terms of delivery to the mucous membrane of the throat was choosen.

Material And Methods: The objects of study were 5 drugs brand Kameton, produced in the form of a metered-dose spray manufacturers of 'Firm 'VIPSMED' (RF), 'Altayvitaminy' (RF), 'Samaramedprom' (RF), 'ESCO-Pharm' (Armenia) and metered-dose aerosol - of 'Pharmstandard' (RF). Measurement of the dynamic characteristics of the spray and the dispersed composition of the spray was carried out by the method of shadow photography with digital image processing using the 'POLIS' system.
