The apparatus "LAZMA ST" consists of two devices - the Analyzer "LAZMA-D" for monitoring the state of peripheral blood flow, lymph flow and oxidative metabolism and the "LAZMA-TEST" block for carrying out temperature and electrostimulation functional tests. Diagnostic methods - laser Doppler flowmetry for the control of microcirculation of blood and lymph and fluorescence spectroscopy for evaluation of coenzymes nicotinamide adenine dinucleotide (NADH) and flavinadenidine dinucleotide (FAD), biomarkers of oxidative metabolism are realized in the LAZMA-D Analyzer. The study is conducted in a state of rest, with cooling - a decrease in the activity of microcirculation and metabolic processes, with heating - an increase in the activity of microcirculation and metabolic processes. The device is intended for wide application in medicine - in surgery, therapy, endocrinology, sports, as the parameters of vital activity on a tissue level are diagnosed.
