[Prediction of infectious complications in surgical patients]. / Prognozirovanie infektsionnykh oslozhnenii u khirurgicheskikh bol'nykh.

An analysis of results of intracutaneous tests with a set of microbe allergens in 121 patients has shown that absence of a skin reaction to all the allergens under test demonstrates a disturbed immune response (incidence of infectious complications was 77%, both lethal outcomes included). The selective hypersensitivity to the injection of certain allergens was due to the carrier state. The normal reaction of slow type hypersensitivity was found in 101 patients (86,4%) and showed no disorders in immune reactivity which was confirmed by the postoperative course without complications. The test of the slow type hypersensitivity is considered to be highly informative and to allow prognosis of postoperative complications.

[Effect of different storage times of blood sera on their hormonal activity]. / Vliianie razlichnykh srokov khraneniia syvorotok krovi na ikh gormonal'nuiu aktivnost'.

Hormonal activity of the sera was studied immediately after blood collection and 6 months, one year and 1.5 years following their storage at a temperature of -20 to 25 degrees C in 10 healthy males aged 18 to 20 years. It was found that differently directed changes in immunologic activity of blood serum hormones took place on long-term storage at low temperatures. The data obtained suggest that the adrenocorticotropic hormone, immunoreactive insulin, protein-bound iodine and follicle-stimulating hormone retain the immunologic activity not more than one year, while the hormone, stimulating interstitial cells, thyrotrophic hormone, somatotrophic hormone, 17-HOCS, testosterone and aldosterone up to 1-1.5 years. During this storage of frozen biosubstrates the recurrent freezing out that produces changes in the immunologic activity of some hormones should be excluded.
