[Study of the clinical efficacy and safety of the scheme of step therapy of nonsteroidal anti-inflammatory drugs and a complex of B vitamins in patients with low back pain].

Objective: The purpose of the study. Comparison of efficacy and safety of treatment with Texared/Neurobion and Amelotex/Milgama in patients with acute dorsalgia.

Material And Methods: An open, observational, retrospective - prospective study involved 70 patients with acute lumbar dorsalgia.

Bulk and water-extractable organic matter from compost: evaluation of the selective dissolution in water using infrared absorbance ratios.

Land application of composts affects concentration and composition of dissolved organic matter (OM) which plays important roles in soil functioning and may have effects on spreading of environmental pollution. Linking between the composition of bulk compost OM and its water-soluble fraction may, therefore, allow better understanding and prediction of the environmental impact of compost added to soil. The objectives of this study were to (i) examine composition-based links between bulk compost OM and water-extractable OM (WEOM), and (ii) evaluate and quantify selectivity of bulk compost OM dissolution, based on infrared (IR) absorbing functional groups.

Application of TiO2-coated alumina beads to dielectric barrier discharge-photocatalyst hybrid process for NO and SO2 removals.

NO and SO2 removal by dielectric barrier discharge-photocatalyst (DBD-P) hybrid process was examined for various conditions of process variables. Alumina beads were coated with TiO2 thin film by a rotating cylindrical PCVD reactor and they were packed inside the cylindrical reactor. The NO and SO2 removal efficiencies can be enhanced by using a combination of dielectric barrier discharge and photodegradation by TiO2.

[Activity of the xenobiotic metabolism system under the effect of chemical pollution of the atmosphere and water].

Functional state of the system involved in biotransformation of xenobiotics in animal liver tissue was studied under conditions of combined chemical contamination of atmospheric air and water simulating the typical real loading. The model loading studied caused in some cases an induction of the microsomal monooxygenases without activation of UDP-glucuronosyl transferase, but simultaneously with accumulation of malonic dialdehyde; this suggests that metabolic alterations observed may be involved in development of pathology.
