The use of spectral analysis methods to determine the age of writing inks is an important forensic task. However, the use of spectral data for this purpose has a number of limitations and difficulties. This paper considers the application of the Raman spectroscopy method to an urgent forensic task.

Analysis covered polymorphism features of 29 genes with variant alleles possibly participating in occupationally conditioned diseases formation and serving as sensitivity markers of these diseases risk. The genes association selected demonstrates reliably changed polymorphism vs.

Investigation ofopioid peptide effect on the production of reactive oxygen species by neutrophils in non-fractionated leukocyte suspension and in purified fraction of peripheral blood neutrophils is disclosed in this work. It was determined that selective delta- and micro-agonists of peptide origin stimulated the spontaneous and suppressed 15 mkg/ml zymosan-induced LDCL (luminol-dependent chemiluminescence) reaction of neutrophils in leukocyte suspension. beta-endorphin was found to render less marked suppressive action on 15 mkg/ml zymosan-induced LDCL, and delta2-agonist deltorphin 2 promoted 15 mkg/ml zymosan-induced LDCL only toward the 25 minutes of the experiment.

In LPS-induced mononuclear cultures polyoxidonium inhibited the IL-6 production and had no statistically significant effect on the synthesis of TNF-alpha and IL-1 beta. Polyoxidonium had no effect on TNF-alpha, IL-6 and IL-1 beta production by purified monocytes.

Interleukin-8 (IL-8) production by leukocytes was inhibited by beta-endorphin at concentrations of 10(-7) and 10(-11) M in the presence of LPS.
