title: [Paramagnetic centers of some biological media in cholecystitis patients].
abstract: OBJECTIVE
  To study paramagnetic centers (PMC) of some biological media in cholecystitis patients.
  
  
  METHODS
  PMC of 81 patients with chronic acalculous cholecystitis and 29 patients with acute calculous cholecystitis were examined using 3-cm radiospectrometer "Rubin" employing low-temperature fixation of biological tissues (77K).
  
  
  RESULTS
  Most informative for diagnosis of cholecystitis exacerbation were the following PMC: in plasma--transferrin Fe3+ and free radicals; in duodenal portion B--Cu2+, free radicals and Mn2+.
  
  
  CONCLUSIONS
  Electronic paramagnetic resonance is a perspective method in diagnosis of chronic cholecystitis exacerbation and in investigations of its pathogenesis.
