INVESTIGATION OF PHOTOCHEMILUMINESCENCE OF HUMAN BLOOD PLASMA
Abstract
The photochemiluminescence of solutions of human blood plasma is conditioned mainly by proteins; the greatest contribution in luminescence is made by serum albumin. In the investigated samples of blood plasma the activators and extinguishers of chemiluminescence are absent. In plasma there are no perceptible quantities of acceptors of protein free radicals. Data were obtained on the regularities of free radical processes which take place in UV- irradiated plasma. On the basis of kinetic experiments it follows that during the irradiation of blood plasma protein free radicals emerge. Satisfactory fulfillment of relationship (1) indicates that the limiting stage is a process of the first order of regrouping of free radicals. Introduction of cysteine and propyl gallate into an irradiated solution of plasma leads to an increase in the constant of rate of drop of luminescence. Addition of eosine yellowish increases the intensity of luminexcence by 10 times.
