Free and lipid myo-inositol in tissues from rats with acute and less severe streptozotocin-induced diabetes. 1977

K P Palmano, and P H Whiting, and J N Hawthorne

Acute diabetes with ketosis was induced in rats by intraperitoneal streptozotocin and also a milder form of diabetes without ketosis by injecting less of the drug. The acutely diabetic rats were killed 72h after injection and the others after either 2 or 13 weeks. Free and lipid myo-inositol was then measured in various tissues and body fluids by g.l.c. of the trimethylsilyl ether. Serum inositol was increased in the acutely diabetic group, whereas liver inositol was decreased. Brain and kidney inositol concentrations were increased in the mildly diabetic animals at 13 weeks and there was a progressive decrease in sciatic-nerve inositol. Lipid inositol of sciatic nerve was decreased in the acutely diabetic group only. Brain lipid inositol concentration was decreased in mild diabetes at 13 weeks. Possible implications of these findings in relation to diabetic neuropathy was discussed.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014018 Tissue Distribution Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios. Distribution, Tissue,Distributions, Tissue,Tissue Distributions
