Resumen

Polyurethane (PUR), as an engineering polymer, is widely used in many sectors of industries. However, the high fire risks associated with PUR, including the smoke density, a high heat release rate, and the toxicity of combustion products limit its applications in many fields. This paper presents the influence of silsesquioxane fillers, alone and in a synergistic system with halogen-free flame-retardant compounds, on reducing the fire hazard of polyurethane foams.

The advantage of biotesting in comparison with the physicochemical analysis of the use of Paramecium caudatum for toxicological studies has been shown. Physical and chemical analysis often fails to detect unstable compounds. In addition, these tools are not possible to determine the ultra-low concentration of chemicals. In addition to the traditional use of laboratory animals, representatives of protozoa have recently been used. In connection with this, a test object of the Sim-plest type was chosen and justified.

In Uzbekistan, the bulk of poisoning is accounted for by alcohol and its surrogates, acids (mainly acetic) and alkalis, various medications, mainly hypnotics and sedatives, organophosphorus and other pesticides. The biological activity of chemical compounds is determined by their structure, physical and chemical properties, dose (concentration) and duration of exposure; features of intake and biotransformation in the body; resistance of tissues and organs to poisons and the individual cha

Resumen

A toxicological and hygienic assessment of the pharmaceutical substance of metformin hydrochloride was performed using various regimens, doses and ways of entry into the body of laboratory animals. The conducted studies allowed us to establish the parameters of the toxicometry of metformin and the features of its biological action, which consist in the absence of an irritating effect on the skin and skin-resorptive properties, an allergenic effect on the body and weak cumulative properties and irritant effect on the mucous membranes of the eyes. Hazard classes of the metformin hydrochloride an

Resumen

As a result of the industrial purification of hydrocarbons from mercaptans, tens of thousands of tons of dialkyl disulphides and their mixtures, the toxicity and hazard of which has not been fully understood, are accumulated annually. The exposure standards have been developed only for dimethyl disulphide. The study was aimed to define toxicometry parameters for diethyl disulphide, disulphide oil, and the mixture of dialkyl disulphides. Toxicology studies involving male outbred rats made it possible to define the median lethal doses and concentrations: diethyl disulphide — after intragastric i

Resumen

Toxicological assessment of combined fungicides proposed for application on cereal spiked crops in Ukraine was performed according approved State Sanitary Norms and Rules. Statistics, bibliographical methods were used in the study. The classes of hazard were established after evaluation of toxicometry parameters, which included assessment of acute oral toxicity, acute dermal toxicity, acute inhalation toxicity, irritation potential to eyes (mucous membranes) and skin, and sensitizing properties. Integral hazard class of the studied formulations was established. Formulations<strong> </stro

Resumen

Introduction. Medicines of natural origin have advantages over synthetic drugs and occupy a significant share in the assortment of pharmacies. Filipendula ulmaria (L.) Maxim., characterized by a chemical composition rich in phenolic compounds and various types of biological activity has the potential in terms of the development of new herbal medicines. In an in vivo experiment, F. ulmaria extract showed immunomodulatory, anti-inflammatory, osteogenic activity and effectively stimulated myelopoiesis in conditions of microbial damage of bone tissue.Aim. Development of an optimal technology for o
