Experimental simulation of radio- and chemoradio stomatitis in rats.

Experimental models of stomatitis developing in response to an isolated (radiation) and combined (radiation and chemical) exposure of experimental animals, were created. The severity of radiation-induced stomatitis was determined by the dose of radiation exposure. Additional exposure to a chemical factor (cyclophosphamide) augmented the destructive effect of ionizing radiation on the buccal mucosa of rats.
