Introduction. The primary goal of this experimental study was to evaluate the efficacy of modified nerve guidance tubes and to compare the efficacy of different modifications of intraluminal space of nerve guidance tubes at bridging large rat sciatic nerve gap.
Materials and methods. To quantify status of neural fibres we utilized silver impregnation by Bilshovskiy–Gross, to identify myelin sheaths – samples were stained by Spielmeyer.
Conclusions. 1. Level of myelination of axons after bridging the gap with hollow guidance tube was the lowest among all other groups of animals and did not depend on regeneration terms. 2. Bridging the gap with different types of modified nerve guidance tubes allowed us to obtain morphometric results reliably equal to “gold standard” of reconstructive surgery – autologous nerve grafting technique.
