[Endovascular Helium-Neon laser irradiation of the blood in the treatment of chronic pyelonephritis]. / Endovaskuliarnoe obluchenie krovi gelii-neonovym lazerom bol'nykh khronicheskim pielonefritom.

The authors analyze the condition of free-radical oxidation and activity of antioxidant system, clinical effectiveness of He-Ne laser therapy of patients with chronic pyelonephritis. It is shown that clinical manifestation of the disease is accompanied with activation of free radical oxidation and hypoactivity of antioxidant system. Endovascular laser hemotherapy stimulates antioxidant system, activity of superoxide dismutase, in particular. A good response and immunomodulation are achieved.

[Autogenous infections in the development of postoperative complications]. / Znachenie autogennogo infitsirovaniia v razvitii posleoperatsionnykh oslozhnenii.

The authors studied the mechanisms of bacterial dissemination in operative wounds in patients after various surgical interventions. It was demonstrated in experiments that during adaptation of the organism to the operative stress, autobacteria enter the blood from the intestinal reservoir and are eliminated through the urinary tract and wound surfaces, if foci of mechanical or toxic destruction exist the autobacteria precipitate in the affected tissues and participate directly in the reparative processes. On the basis of the obtained data it is suggested that the phenomenon of activation and persistence of endogenous microflora exists as one of the syndromes of adaptation of man to the aggression factor, which is aimed at revealing and removing the foci of tissue destruction developing as the result of exposure to the effect of the stress.

[Asymptomatic bacteriuria as the manifestation of a syndrome of the activation and persistence of endogenous microflora in dynamic human adaptation to stress]. / Bessimptomnaia bakteriuriia kak proiavlenie sindroma aktivatsii i persistentsii éndogennoi mikroflory v dinamike adaptatsii cheloveka k stressu.

The analysis has been performed of the mechanisms underlying the origin of asymptomatic bacteriuria as an adaptive reaction in response to surgical aggression. The experiments proved penetration of autobacteria from the intestine to blood channel and organic structures of the animals in the course of adaptation to an operative trauma and consequent elimination of the bacteria from the body. It was observed that endogenic microflora participates in regeneration of macroorganism structures which have lost their morphofunctional integrity due to mechanic and toxic aggression. It is suggested that activation and persistence of endogenic microflora may arise to identify and abolish foci of aseptic destruction during the aggression in adaptation to stress.

[The enzyme function of cationic transmembrane transport and its relationship to the homeostatic indices of patients with chronic pyelonephritis]. / Funktsional'noe sostoianie fermentov kationnogo transmembrannogo transporta i ikh vzaimosviaz' s nekotorymi pokazateliami gomeostaza u bol'nykh khronicheskim pielonefritom.

The paper examines the relationship between the clinical manifestations of pyelonephritis and the functional activity of enzymes of cation transmembrane erythrocyte transport (Mg(2+)-, N(+)-K(+)-, Ca(2+)-ATPases). An individual analysis ascertained that the patients who showed a low Ca(2+)-ATPase activity had marked signs of inflammation in the body, as evidenced by ESR, seromucoid and fibrinogen concentrations. These patients had more significantly depressed immune defense mechanisms as reflected by the levels of immunoglobulins, T-lymphocytes, complement, the neutrophil phagocytosis, and urinary IgA concentrations). Variations were also found in examining the excretion of a number of metabolites. There was a substantial decrease in urea, creatinine, titrated acid, phosphorus excretions in patients with deficient Ca(2+)-ATPase activity than in those with its high activity. It was concluded that there was a relationship between some clinical manifestations of pyelonephritis and the functional activity of enzymes of cation transmembrane transport. To treat metabolic disorders, membrane-protective agents are recommended to include into combined therapy.

[The treatment of coralliform nephrolithiasis]. / Lechenie korallovidnogo nefrolitiaza.

A total of 184 patients with dendritic nephrolithiasis (74.5% females and 25.5% males) were under study. It was established that in more than half of them the disease developed from the infectious inflammation of the urinary tract. Based on the findings, the authors supposed that in these patients the initial instability of cellular membranes was associated with a decrease in nonspecific resistance which was unfavourably complicated by infection of the urinary tracts and the formation of calcium phosphate calculus. As the presence of friable (low-contrast) calculi in the state of growth is accompanied by a severe inflammation, a continuous nonoperative treatment is mandatory. When the growth of the calculus is stopped and confirmed by its high-contrast dense X-ray shadow and the signs of inflammation ceased the authors insisted on the conduction of the 3-4-week inpatient preoperative management. The latter should include the administration of wide-range antibiotics, drugs for potentiation of nonspecific resistance and the complex of vitamins. Subcortical pyelolithotomy with partial nephrotomy is a method of choice in case of a "dry kidney". An average postoperative bedtime comprised 22.3 days.
