[An immunoregulatory effect of endoglucanase preparations on plant resistance to fungal infections]. / Immunoreguliruiushchee deistvie fermentnykh preparatov éndoglikanaz na ustoichivost' rastenii k gribnoi infektsii.

Effects of enzymatic preparations--pectomacerin, hemicellulase, and Trichoderma viride 13/10 cellulase--on the plant immunological status were studied by examples of the pathosystems carrot root-white rot agent (Sclerotinia libertiana) and carrot root-black rot agent (Rhizopus nigricans). It was demonstrated that these preparations reduced the damage of infections, namely, decreased the permeability of cell membranes in infected tissue and stimulated its defense responses, which manifested itself in a stable elevation in the content of phenolic compounds and formation of tissue protective barriers.

[Characteristics of the distribution of transplantation antigens of the HLA system in patients with acute pyelonephritis]. / Osobennosti raspredeleniia transplantatsionnykh antigenov sistemy HLA u bol'nykh ostrym pielonefritom.

The interrelation between transplantation antigens of the HLA system and predisposition to acute pyelonephritis (PN) were studied in 81 patients, of them 36 with acute serous PN and 45 with acute purulent PN. HLA phenotype was identified with a routine lymphocytotoxic microtest in which a home-made typing panel of HLA antiserum to antigens of A and B loci was used. 150 healthy donors were subjected to control typing. Variance in HLA frequency reliability in patients and controls was verified with chi 2 criterion for tables 2 X 2. The study demonstrated higher frequency of B8 and B14 and lower of Aw19 and B35 antigens in patients with PN versus the healthy controls. Differential analysis with regard to the clinical course of the disease revealed that predisposition to acute serous PN was associated with the occurrence of A3 and B14 antigens while A10 and B8 antigens were indicative of acute purulent PN. It has been stated that purulent PN is developing in presence of secondary deficiency of T and B immune systems. Cross-reacting antigens B14 and B8, as well as splitting antigens A10 and A25 lend more ground to varying clinical course of the disease. HLA antigen B35 is found associated with the development of acute PN resistance.

[Causes of death at the early post-traumatic period]. / Prichiny smerti v rannem periode posle travmy

The causes of lethal issues in the acute period in 897 patients with grave associated injuries are analysed in detail. A definite morphological substrate of injuries would underline grave functional disturbances. The principal causes of mortality in trauma were as follows: acute massive blood loss (35.5%), primary damage of the ventilatory apparatus and acute respiratory insufficiency (24.8%), impairment of the specific function of vitally important organs (29.7%), or various combinations of these leading mechanisms of tanatogenesis. Most frequent hazards of an acute period of grave injury in the practice of treatment and reanimation (delayed diagnosis, inadequate infusion therapy, aspiration and regurgitation) are emphasized. Based on the results of the analysis made, some trends of improvement of modern methods of reanimation and treatment are delineated.
