[Restoration of muscle contractile properties after partial and complete denervation]. / Vosstanovlenie sokratitel'nykh svoistv myshtsy posle chastichnoi i polnoi denervatsii.

The subject of this experimental study was the isometric contractile properties of rat tibialis anterior muscle, number and average size of the motor units as well as type content and type-grouping of muscle fibres according to SDH activity in the same muscle after total and partial denervation (crushing the sciatic nerve and L4). It has been shown that in the process of reinnervation after total and partial denervation, quantitative differences with the general tendency in the dynamics of restoration of contractile properties of the whole muscle are found at different dynamics of restoration of electromyographic and muscle histochemical characteristics of motor units.
