[The effect of hyperbaric oxygenation on the urea content of the saliva in acute and chronic soft-tissue inflammation in the maxillofacial area]. / Vliianie giperbaricheskoi oksigenatsii na soderzhanie mocheviny v sliune pri ostrom i khronicheskom vospalenii miagkikh tkanei v cheliustno-litsevoi oblasti.

Urea levels were measured in the saliva of 30 patients with acute and chronic maxillofacial inflammation treated with multiple modalities including hyperbaric oxygenation (HBO). Urea concentrations were evaluated before, in the course of and after HBO session. A total of four 40-min sessions were made (1 session a day, 1.5 atm). Elevated concentrations of urea after HBO are thought adaptive, serving for elimination of ammonia overproduction in hyperoxia. Urea measurements in the saliva can be used for prediction of oxygen intoxication in the HBO-exposed patients.

[Immunological and biochemical indices during the use of hyperbaric oxygenation for treating patients with jaw deformities]. / Immunologicheskie i biokhimicheskie pokazateli pri ispol'zovanii giperbaricheskoi oksigenatsii dlia lecheniia bol'nykh s deformatsiiami cheliustei.

Analysis of changes in the immunologic and biochemical parameters in the patients operated on for congenital deformations of the maxillary bones and poorly joined fractures has shown an increase of the immunologic reactivity under the effect of hyperbaric oxygenation therapy administered after surgery to patients with initially reduced levels of these parameters. Urinary excretion of hydroxyproline was found unchanged in patients with maxillary deformations.
