The fine lamellar fault structure of primary MC carbide particles in the heat-resistant Fe-Cr-Ni-C alloy of the HP series (0.45C-25Cr-35Ni) in the cast condition has been revealed using transmission electron microscopy. The lamellar fault structure is regarded as an inheritance of the initial melt structure.

The influence of isolation procedures on physico-chemical properties of human serum albumin (HSA) has been studied using differential scanning calorimetry and infrared spectroscopy. Fractionation of blood plasma with polyethylene glycol (PEG) followed by ion-exchange chromatography produced healthy donor albumin whose melting thermograms were identical to those of the HSA in non-fractionated plasma. The endotherms of HSA samples isolated by affinity chromatography (AC) and native electrophoresis (EP) are bimodal as distinct from monophasic endotherms of PEG-HSA preparations.

The authors suggest a method for the detection of 'medium molecules' to be used for rapid diagnosis of poisoning. They present their arguments in favor of a higher specificity of this method as against other rapid methods for 'medium molecule' detection in biologic fluids of the body. The authors' data evidence a high correlation between the results of the suggested method and gel filtration technique.
