[Determination of oxidative activity of ceruloplasmin using Ravin's method in patients with laryngeal carcinoma]

According to Ravin's method an oxidative activity of ceruloplasmin was determined in the group of patients with carcinoma of the larynx before and after a surgical treatment, in the group of patients with inflammatory lesions in the upper respiratory tract and in 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 surgical treatment) in comparison to the group of patients suffering due to inflammatory diseases of the upper respiratory tract and 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 a previous surgical treatment was observed.
