Polygonum glabrum is being used in traditional and folklore medicine to treat pneumonia and jaundice. Plant roots are used in ayurvedic preparations to treat fever and colic. The leaves are used as diuretic agents and process vermifuge action. Plant decoction is also used in the treatment of Rheumatism. Besides having many uses and folklore claims, herbal medicines are to be thoroughly investigated for their toxicity also. Therefore this work is being carried out to examine the toxicity of the drug and established dose is safe to use in the clinical stage. The current research studied the acute and chronic toxicity of Polygonum glabrum root extract in rats. It is proved that there was no change in any parameter tested both in acute and chronic toxicity, which means the extract is safe and non-toxic at the dose of 2g/kg also.

Field And Laboratory Conditions

Today, there are personal protective equipment, which due to their weight and size characteristics and design features can aggravate professional activity. This is characterized by an increase in the load on several major systems of the employee's body, including the cardiorespiratory system, which can cause the development of occupational pathology. The study of the functions of the cardiorespiratory system of humans in the process of his work is an important task in biomedical tests such as PPE, aggravating their professional activities and future means of individual protection from heavy labor and industrial exoskeletons. The aim of the study is to determine the possibility of using ergospirometry for the physiological assessment of personal protective equipment and industrial exoskeletons. Main part. In medical practice and high-performance sports, ergospirometry is considered the "gold standard" for functional assessment of the cardiorespiratory system. There are very few studies showing the use of ergospirometry for the purpose of physiological assessment of personal protective equipment. Results of research works in which ergospirometry was used in medicine, sports, as well as on the physiological and hygienic assessment of combat equipment, various types of personal protective equipment, including new promising personal protective equipment of the musculoskeletal system-industrial exoskeletons. The use of ergospirometry made it possible to register the main indicators of the human cardiorespiratory system both in field and laboratory conditions and allowed forming an objective conclusion about the dynamics of the degree of stress of the human cardiorespiratory system when using personal protective equipment and industrial exoskeletons with various weight and size characteristics. Thus, the use of ergospirometry both in isolation and in combination with other methods allows us to solve problems related to biomedical testing of personal protective equipment and industrial exoskeletons.

Polyvinyl Nitrate

Water containing polyvinyl nitrate was experimentally assessed on the basis of organoleptic, general sanitary and toxicological indicators of harmfulness. It was established that that the compound did not change water organoleptic properties but produced a negative impact on viability of saprophytic microflora , nitrification processes and biochemical oxygen demand. Besides, in tests on animals. the substance caused acute, sub-acute and chronic toxicity. Based on those signs of harmfulness, threshold levels of exposure were established. Data obtained were taken into account for substantiation of MAC (Maximum allowable concentration) of polyvinyl nitrate in water bodies.
