[The biological role of carnosine in excitable tissues].

The authors summarize the data about characters of histidine-containing dipeptides (HCD) carnosine and homocarnosine in excitable tissues. The value of their antiradical, pH-buffer and metal-chelating characters is presented. The authors analyze data on participation of some cell membrane receptors in biological effects of HCD.

[Factors affecting the concentration of serum ceruloplasmin in Wilson-Konovalov disease].

An oxidase activity of ceruloplasmin was studied in blood serum of 335 patients with Wilson-Konovalov disease before specific copper-obviating treatment. Coefficient for calculation of concentration units depending on optic density was estimated by means of copper content measurement in ceruloplasmin. The well-known fact of ceruloplasmin content decrease in the Wilson-Konovalov disease was supplemented by the new data involving age-sex differences and the age-dependent dynamics as compared with healthy persons and with a group of 827 patients with other neurological diseases.
