Histology and Ultrastructure of the Nephron and Kidney Interstitial Cells in the Atlantic Salmon ( Linnaeus 1758) at Different Stages of Life Cycle.

This article presents data on the mesonephros histology and ultrastructure in the Atlantic salmon from the Baltic Sea and Barents Sea populations, with an emphasis on comparisons between the following ontogenetic stages: parr, smolting, adult life at sea, the adults' return to their natal river to spawn, and spawning. The ultrastructural changes in the renal corpuscle and cells of the proximal tubules of the nephron occurred as early as the smolting stage. Such changes reflect fundamental alterations during the pre-adaptation to life in saltwater.

New Data on Nephron Microanatomy and Ultrastructure of Senegal Bichir ().

This study presents new data on the microanatomy and ultrastructure of nephrons. It was shown that the diameter and ultrastructure of renal corpuscles, a well-developed neck segment, and ultrastructure of two types of epithelial cells of the proximal tubule are ancestral signs of the modern population of associated with habitat conditions in the aquatic environment. The outer diameter of the tubules, the height of the epitheliocytes, the presence of two types of epithelial cells of the intermediate and distal tubules of the corresponding ultrastructure, and a large area of nephrogenic tissue are progressive features of the modern population of , associated with adaptation to air respiration and periodic terrestrial migrations, which were formed at the early stages of evolution of convergently with lungfish and amphibians.

[Clinical and morphological parallels in lung lesions associated with hemorrhagic fever with renal syndrome].

The authors report the results of clinical examination of the respiratory, organs of 97 patients with hemorrhagic fever and renal syndrome (HFRS) with confirmed Puumala serotype. Retrospective analysis of 16 fatal cases is presented. It is shown that patients with moderately severe and severe forms of the disease exhibit early clinical and X-ray signs of pulmonary lesions and respiratory insufficiency Some of them suffer acute respiratory distress syndrome confirmed by morphological findings at autopsy.

[Clinical effectiveness of the infusion therapy under control of the transesophageal dopplerography in acute period of severe combined trauma].

In 72 patients with combined trauma the impact of volume and consistence of infusion therapy on severity of the disease, frequency and severity of infectious complications, duration of MV and ICU stay was assessed. The patients were divided into 2 groups depending on the volemic status control method and infusion algorithm. The main group (35 patients) was controlled by transesophageal dopplerography Cardio Q apparatus ("Deltex Medical", GB) and the infusion therapy was carried out under the control of stroke volume and Ftc.
