[A novel experimental method for evaluation of effect of nitrites on blood deoxygenation kinetics].

A new method for studying the oxygen-binding properties of blood is proposed, which is based on the analysis of transient processes on oxygen electrodes. The method was used to study the effect of sodium nitrite on the kinetics of dissociation of oxyhemoglobin in rat blood. It was shown that the rate of oxygen transport decreases at nitrite concentrations 1-5 mg/100 g body weight.

Detection of lactate dehydrogenase isoenzymes in single mammalian oocytes during cleavage by a micromodivication of disc electrophoresis.

A micromodification of the method of disc-electrophoresis in glass capillary tubes is described. It can be used to study the protein composition and activity of lactate dehydrogenase isoenzymes in single rat and mouse oocytes during clevage.
