abstract：:The impaired Na(+)-K(+)-ATPase activity in peripheral nerve from diabetic rats is prevented by dietary myo-inositol (MI) supplementation in vivo and corrected by protein kinase C (PKC) agonists in vitro, suggesting that PKC may mediate the effects of nerve MI depletion on Na(+)-K(+)-ATPase activity. However, little is...
