[Mitotic activity of epithelium in crypts of rats' empty intestine and tissue basophils in the event of intestinal syndrome of radiation disease treated with poly-radio-modification].
In the experiment with white mongrel puberal male rats, morphological and statistical methods were used to study mitotic activity (MA) in the crypt epithelium in the empty intestine and morphofunctional state of tissue basophils (TB) in the intercrypt stroma after a single gamma-irradiation at the dose of 10 Gy and polyradiomodification including exposure to EMR in the UHF range (2.4 GHz, 10 mW/cm2, 2.5 min), normobaric oxygen (NO) or hypoxic gaseous mixture (HGM) containing 8% of O2 and 92% of N2. Polyradiomodification with the use of EMR and HGM or NO was found to be more effective as compared with the use of each of these radioprotective methods separately. A combination of EMR + HGM + II gave more apparent and earlier effect of MA recovery and TB activation as compared to EMR + NO + II.
