ABSTRACT
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 dent¼ line. MATERIALS AND METHODS: The study involved toothpastes of «MEXIDOL dent¼ 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 («MEXIDOL¼) determined the choice of potentiometric titration method for the assessment of the stability of antioxidative activity. RESULTS AND CONCLUSION: The study confirmed the stability of antioxidative activity of the active compound 2-ethyl-6-methylpiridine-3-ol succinate of toothpastes of the «Mexidol dent¼ line during shelf life.

The subject matter of the investigation is to compare the metered dose nasal sprays containing the long-acting decongestant oxymetazoline from the different manufacturers according to the dispersion quality: the dose quantity in one packing, the dose mass reproducibility, imprint area on the planar imitation model. The tests were conducted: «The number of doses per package¼, «Mass uniformity of the dose¼, «Irrigated area (on the planar imitation model)¼. The analysis of nine oxymetazoline nasal sprays demonstrates that the optimal result is achieved while usingVicks Sinex.

We studied the efficiency of bubbling air as a method of detoxification of the blood plasma and its mixtures with plasma substitutes from CCl4. The efficiency of detoxification depended on the characteristics of the obtained foams: foam forming ability, frequency rate, dispersion, stability of a foam skeleton, syneresis, etc. A hardware-software complex for extracorporeal blood plasma detoxification was developed and the programs for the control and regulation of this process were tested. Physical and mathematical models of toxicant excretion from the body during extracorporal blood detoxification were proposed. Verification of the mathematical model demonstrates high correspondence between the theoretical and experimental data.
