[The role of nitric oxide in antimicrobial defense in chronic tonsillitis].

Nitric oxide (NO) degradation products were assayed in lacunar discharge in chronic compensated and decompensated tonsillitis before and after treatment on the ultrasound device Tonsillor. It was found that pretreatment concentration of NO degradation products (nitrites and nitrates) differed in decompensated and compensated chronic tonsillitis. The treatment reduced content of NO degradation products in both forms of tonsillitis. Use of indirect values of NO concentration are proposed for differential diagnosis between chronic compensated and decompensated tonsillitis as well as for monitoring of treatment efficacy.
