Fourteen patients with complicated uremia and multiple organ dysfunction syndrome were treated by renal replacement therapy (RRT), by hemodialysis and hemodiafiltration. Control group consisted of 14 age-matched convalescents without clinical and laboratory signs of uremia and systemic inflammatory response syndrome. The potentialities of Integral Diagnostic Expert Analytical System (IDEAS) based on the spectrophotokinetic (SPK) technique (ECOTEST, Russia; Thermo Labsystems, Finland) were evaluated on the basis of objective evaluation of clinical condition of end-stage renal disease patients. SPK technology proved to be a highly informative method of automated diagnosis, which allows monitoring the dialysis efficiency, detecting combined diseases and poor system's biocompatibility, which, in turn, permits correction of the treatment and realization of a differentiated approach to the choice of RRT method.
Variable cDNA regions in the VP2 gene of 24 isolates of infectious bursal disease virus (IBDV) isolated in Russia in 1993-1996 were amplified by the "nested" PCR and sequenced. The primary structure analysis of the VP2 gene variable region revealed 2 major groups of IBDV isolates. The first group consisted of the isolates with the structure identical or closely related to the highly virulent European strains CS89, 74/89A, 661, JY86, and DV86, the second group included the isolates with a high level of homology to the vaccine strains PBG98 and Cu-1. In addition, two isolates with original structure were identified, which differed from previously studied strains.
By means of noninjective methods of investigation a specific capillary network of a sinusoidal type, peculiar arteriolovenular anastomoses, additional reservoirs in the area of postcapillaries and venules described in the microcirculatory bed of the spinal dura mater. The peculiarity of this vascular bed is thought by the authors to be connected with liquor resorption from the subdural space of the spinal cord.
