Extraction of basic metabolites of monomethyloxybenzene isomers from aqueous solutions

The results are presented of extraction of 1-methyl-3,4-dioxybenzene, 1-methyl-2,5-dioxybenzene and 4-oxybenzene acid from aqueous solutions with hydrophobic and hydrophilic organic soluvants. It is shown that the degree of extraction depends on the nature of the extragents and pH of the aqueous phase medium. Extraction multiplicity for obtaining necessary quantities of the compounds is calculated.     

Pathomorphology of the endocardium and myocardium in the heart injury

Light, polarization, luminescent microscopy, phase contrast, special staining methods and scanning electron microscopy were used for studying sections and fragments of the endocardium and myocardium from 123 patients who had died of heart contusion and ischemic heart disease and from 50 rats with experimental heart contusion. The morphological classification of heart contusion and differential-diagnostic table of myocardial alterations due to contusion of the heart and ischemic heart disease are proposed to facilitate pathomorphological diagnosis of heart contusion. The classification of pathomorphological signs in heart contusion is presented.     

Modern structure of the pancreatic injuries

Current structure of pancreatic traumas of peace time is considered. The dynamics, mechanism and characteristics of pancreastic injury are described. Surgical treatment of pancreatic injuries and causes of their inadequate management are analysed. This will contribute to improvement of the quality of treatment of pancreatic injuries and of expert evaluation.     

Estimation of shooting distance for a pneumatic gun MP-654 K loaded with small lead shots

The experimental material has shown possibility of definition of shooting distance and some technical characteristics of the barrel of the pneumatic gun loaded with shots.     

Forensic-medical assessment of terroristic chemical attacks

By potential damage, chemical terroristic attacks are much more dangerous than terroristic bombing. To fight chemical terrorism it is necessary to create the system of medical-environmental defense of the population. In line with emergency medicine, forensic medical service is a very important element of the antiterroristic defense. The activity of forensic-medical experts in the field of terroristic chemical attack is analysed.     

Assessment of unfavorable outcomes of dental care provoked by the patient

Some causes of ineffective dental care because of the patient's negligence were analyzed. In 16 cases the patients ignored recommendations of the dentist and missed visits to the doctor. As a result, the patients developed complications leading to esthetic dissatisfaction, prolonged treatment, repeated prosthetic management.
