Sciatic Nerve Plastic Surgery using Autologous Adipose Tissue.

Unlabelled: is to study structural alterations of autologous omental adipose tissue in a silicon conduit and to evaluate its possible use for regeneration of the sciatic nerve in diastasis.

Materials And Methods: Mature outbred male Wistar rats have been used in the study. The animals were divided into 7 experimental groups with complete transection of the sciatic nerve on the right side at the mid-third level of the thigh.

Reconstruction of the Rat Sciatic Nerve by Using Biodegradable and Non-Biodegradable Conduits.

Unlabelled: was to compare two types of conduits made of either non-resorbable Reperen or resorbable Tissucol for their effects on the regeneration of the rat sciatic nerve under conditions of stump diastasis.

Materials And Methods: The experiments were carried out using outbred white male rats of the reproductive age (n=14). The animals were divided into three groups: group 1, intact (n=5), used for studying the morphology of the sciatic nerve; group 2 (n=4) - nerve plastic surgery was performed using a conduit made of non-resorbable Reperen; group 3 (n=5) - surgery was performed using a conduit made of resorbable Tissucol.

Ultrastructural Morphological Characterization of Right Atrial and Left Ventricular Rat Cardiomyocytes during Postreperfusion Period.

Immunocytochemistry and transmission electron microscopy were employed to examine the ultrastructural morphometric parameters of the left ventricular cardiomyocytes and right atrial secretory myocytes in rats during early and delayed postreperfusion periods. The revealed alterations in these cells are stereotypical, but differed by their severity, probably due to specific morphofunctional peculiarities of these heart structures.

[Transcranial dopplerography and variational pulsimetry in the diagnosis of cerebral angiodystonias in children].

The hypoxemia-hypercapnia test with closed-space breathing has been performed in 71 children aged 9-15. The examinees comprised three groups: healthy controls (n = 12), patients with latent cerebral angiodystonia (n = 9), patients with clinical cerebral angiodystonia (n = 50). The patients could hardly tolerate closed-space breathing.
