Paper Abstract

Assessment of the carboxyhemoglobin photodissociation has been performed under the native conditions. This investigation has a great importance for the development and creation of completely new approach for the treatment of carbon monoxide poisoning based on the photoinduced dissociation of carboxyhemoglobin. Photodissociation was registered on the experimental setup with crossing laser beams were pulsed Nd:YAG laser at the second harmonics wavelength (λ=532 nm) was used as a source of photolyzing radiation. Buffered solutions of whole human peripheral blood (PBS, pH=7.4) and diluted hemolized human peripheral blood were used. We found optimal parameters for the registration of the photodissociation such as using of buffered solutions of the whole human peripheral blood with the concentration of carboxyhemoglobin around 50% detection of dissociation of carboxyhemoglobin at the maximum of absorption within the Soret's band (435 nm). Dependence of photodissociation efficiency on the concentration of the complex in the tested solutions, as well as on the photolysis radiation intensity in both types of solutions was proved.
