Changes in Hemoglobin Properties in Complex with Glutathione and after Glutathionylation.

Hemoglobin is the main protein of red blood cells that provides oxygen transport to all cells of the human body. The ability of hemoglobin to bind the main low-molecular-weight thiol of the cell glutathione, both covalently and noncovalently, is not only an important part of the antioxidant protection of red blood cells, but also affects its affinity for oxygen in both cases. In this study, the properties of oxyhemoglobin in complex with reduced glutathione (GSH) and properties of glutathionylated hemoglobin bound to glutathione via an SS bond were characterized.

[Local permanent intraarterial antimicrobic therapy in postoperative period at the patients with cholangitis].

Method of local permanent intraarterial antimicrobic therapy was used in postoperative period at the patients with acute cholangitis. The method includes transfemoral catheterization of hepatic artery and permanent infusion of ceftriabol (2.0 ml per day) and metronidazol (1.

[Pharmacological correction of ketamine-impaired spatial memory of rats].

Ketamine in dose 10 mg/kg increased the number of erroneous choices of rats with spatial strategy and didn't effect searching accuracy of rats with non-spatial strategy in 8-arm radial maze. Ketamine in doses 1 and 5 mg/kg disrupted rat short-term memory in delayed response reaction. Physostigmine and aspartic acid, but not haloperidol, diminished ketamine amnesia, therefore ketamine impaired the interaction of cholinergic and glutamate/aspartatergic neurons of hippocampal areas.
