[Oxidase activity in patients with laryngeal carcinoma treated by radiotherapy]

According to Ravin's method an oxidative activity of ceruloplasmin was determined in the group of patients with carcinoma of larynx before and after rtg-therapy and at the control group of healthy individuals. As a result of this assay the significantly increased of oxidative activity ceruloplasmin was obtained in the individuals with the carcinoma of the larynx before rtg-therapy in comparison to the group of healthy subjects. Simultaneously a significant decrease of the oxidative activity of serum ceruloplasmin in the individuals with carcinoma of the larynx after rtg-therapy was observed.
