[Fibronectin and its significance in pyelonephritis].

Fibronectin levels were measured by enzyme immunoassay in 68 patients with pyelonephritis and 10 patients with chronic cystitis. The patients with chronic cystitis, acute and chronic non-obstructive pyelonephritis exhibited significantly high average blood fibronectin levels, whereas those with chronic obstructive pyelonephritis displayed the levels slightly different from those observed in healthy individuals. Hypofibronectinemia was detected in 23.3% of patients with chronic pyelonephritis. Preincubation of the neutrophils isolated from pyelonephritis patients with fibronectin increased the initially low phagocytic capacity without enhancing their metabolic activity. In experimental pyelonephritis, administration of exogenous fibronectin was demonstrated to contribute to a rapid bacterial elimination from the kidneys, to decrease the intensity of an inflammatory response, to prevent renal histostructural lesions, to enhance the functional activity of immunocompetent cells and to stabilize their membranes. The findings may serve the basis for using fibronectin in clinical practice as a promising agent to treat pyelonephritis.

[The effect of bacterial polysaccharides on the course of a Mycoplasma infection].

Polysaccharides of Clavibacter michiganense have been studied for their effect on Mycoplasma infection. It is established that content of T-lymphocytes truthfully increased in the groups of animals whose PS 1 and PS 2 were administered both with protective and medical purpose as compared with that in a group of animals with natural course of mycoplasmosis. Under these conditions the effect of polysaccharides on T-helpers were not evidently expressed, while they exerted considerable effect on T-suppressors, normalizing their high index in the animals infected by Mycoplasma hominis. Polysaccharides also exerted a normalizing effect on the content of T-killers, whose level in the animals with natural proceeding of mycoplasmosis was considerably decreased. One can observe a decrease of content of B-lymphocytes (which approached the level of their control in a group of conditionally healthy animals) under the effect of polysaccharides as compared to infected animals. Metabolic processes are activated in immunocompetent cells as affected by polysaccharide. Results obtained when studying the effect of polysaccharides on immunologic factors in the animals with mycoplasma infection as well as histomorphological data confirm the above evidences that polysaccharides of C. michiganense are promising immunomodulators.

[The use of thienam for the emergency antibacterial therapy of acute suppurative pyelonephritis].

Results of a clinical and microbiological investigation designed to study thienam permit recommending this drug as an urgent agent of choice in acute purulent pyelonephritis. The drug is well tolerated. Among other benefits is extremely high sensitivity of bacteria (pathogenic and conditionally pathogenic) to the medication, achievement of an expected clinical effect within a short time since its therapy institution.

[New data on the etiological factors in acute pyelonephritis].

Spectrum of microbe agents of acute pyelonephritis has been studied. It is shown that Mycoplasma hominis plays an important role in etiology of acute pyelonephritis besides the already known enterobacteria and Gram-positive cocci. It is also established that mycoplasmal pyelonephritis more often develops in patients with the diseases of urinary blade (cystitis) and genital organs. Results of serological investigations which confirm etiological role of isolated microorganisms in the initiation of acute pyelonephritis are presented.
