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.     

Criteria of personal identification by the hyoid bone

We studied 16 sizes of the hyoid bone (HB) from 158 corpses of known gender, Russians, who had died at the age over 15 years by the K. Miller et al program (1998) and 205 back projection electroroentgenograms of the neck of patients of the traumatological hospital in the town of Kirov. HB skeletization was made by the enzymatic drug enzyme. SPSS package and multidimentional statistics (regression and discriminant analyses) were used for data processing. It was established that HB is an informative object of forensic medical personal identification allowing determination of the body length and gender as well as anatomical, x-ray and osteometric individual features. Precision of human body length diagnosis by HB is 6.71-7.26 cm. Therefore, this method should be used in combination with the diagnosis by long tubular bones. Diagnosis of human gender by osteometric signs of HB based on one-dimentional discriminant analysis is feasible in 80-85%, based on canonical discriminant analysis--in 91.1% cases. The method of anatomic, osteometric and roentgenological assessment of HB individuality can be used in personal identification by intravital x-ray of cervical organs and in traumatic defects of HB. The methods may be applied in forensic medical practice in expert examination of body fragments or isolated bone fragments.
