DEVICE FOR NON-INVASIVE POTENTIOMETRIC DETERMINATION OF OXIDANT/ANTIOXIDANT ACTIVITY OF BIOLOGICAL TISSUES

摘要

FIELD: medicine.;SUBSTANCE: group of inventions relates to medicine, cosmetology, production of food products, vitamins, food supplements, drugs and describes versions of device for realisation of non-invasive potentiometric determination of oxidant/antioxidant activity of biological tissues, which includes device for measuring potentials and double-sided electrode, made in form of plate with similar working surface, covered with electricity-conducting gel, containing mediator system. Electrodes are fixed on biological tissue in such a way that one working surface, playing role of measuring electrode, is in direct contact with biological tissue via gel, second working surface pale role of comparison electrode. Electrodes contact with each other via gel, with oxidant/antioxidant activity being determined by formulae with application of difference between final and initial potentials.;EFFECT: simplification, as well as increase of accuracy and reliability of determination, is achieved.;14 cl, 3 tbl, 4 dwg
