Computer analysis of erythrocyte catalase activity in diagnosis of mild brain trauma and concussion

A complex investigation of catalase activity in erythrocytes was conducted basing on the results of computer quantitative morphometry of histochemical examination of blood samples from persons with mild craniocerebral trauma. It was found that erythrocytic catalase activity correlates with severity of brain trauma. A novel technique of objective histochemical diagnosis of trauma is described. It provides objective grounds for expert conclusions. Differential features of erythrocytic shape were defined in a small series of micropreparations vs the rest blood samples.     

Forensic medical diagnostics of nitrate and nitrite intoxication

Nitrates and nitrites, accumulating in toxic concentrations in soil, plants, water and foodstuffs, can cause lethal intoxication. The method of isolation, identification and quantitation has been elaborated for their diagnosis. It is based on the isolation of water and subsequent chromogenic test plus photoelectrocolorimetry.     

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.     

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.
