Paramagnetic centers of some biological media in cholecystitis patients

Aim. To study paramagnetic centers (PMC) of some biological media in cholec ystitis patients. Materials and methods. PMC of 81 patients with chronic acalculous cholecyst itis and 29 patients with acute calculous cholecystitis were examined using 3-cm radiospectrometer "Rubin" employing low-temperature fixation of biolo gical tissues (77K). Results. Most informative for diagnosis of cholecystitis exacerbation were the following PMC: in plasm - transferrin Fe3+ and free radicals; in duoden al portion B - Cu2+, free radicals and Mn2+. Conclusion. Electronic paramagnetic resonance is a perspective method in di agnosis of chronic cholecystitis exacerbation and in investigations of its pathogenesis.
