Method of preparation of samples for spectroscopic study of interaction of laser irradiation with blood and bone marrow

The evolution of absorption spectra of blood and bone marrow during keeping has been studied for different sample--anticoagulant--buffer ratios and different anticoagulants. It has been shown that the highest stability of spectra is achieved in the case of delution by isotonic NaCl solution with trylon `B' added. Preliminary experiments on laser irradiation effect on blood and bone marrow in vitro were performed.
