Effects of nerve cross-union on rat intracellular potassium in fast-twitch and slow-twitch rat muscles

, : Effects of nerve cross-union on rat intracellular potassium in fast-twitch and slow-twitch rat muscles. Journal of Physiology 216(1): 171-179

1. Electrolytes of normal, self-innervated and cross-innervated extensor digitorum longus and soleus muscles of rats have been determined.2. [K](i) was 173 m-equiv/l. for both normal and self-innervated extensor digitorum longus. In cross-innervated extensor digitorum longus it was reduced to 159 m-equiv/l.3. For normal and self-innervated soleus, [K](i) was 150 m-equiv/l. and 154 m-equiv/l. respectively. In cross-innervated soleus it was increased to 182 m-equiv/l.4. The content and distribution of most other electrolytes of cross-innervated soleus, as well as its weight, were not significantly different from those of controls. On the other hand, cross-innervated extensor digitorum longus weighed about half as much as controls and contained markedly elevated Na(+), Cl(-) and extrafibre water and reduced non-collagenous protein and intrafibre water.5. It is concluded that [K](i) of fast-twitch and slow-twitch muscle fibres are under neural regulation. Possible mechanisms for this regulation are discussed.
