title: Distribution of 1,5-anhydro-D-glucitol in normal, diabetic, and perfused rat bodies.
abstract: The concentration of 1,5-anhydro-D-glucitol (AG) was determined in various organs and tissues of normal rats and rats rendered diabetic with streptozocin, using an AG-assay method in which AG was extracted after acid hydrolysis of the whole tissues. The organs and tissues examined included skin, muscle, liver, and kidney. The plasma of control rats contained 3-12 micrograms/ml of AG. In these rats, all the organs examined also contained AG at concentrations not much lower than that in the corresponding plasma, except for adipose tissues and testis, which have relatively small water spaces; the latter two contained AG at relatively low concentrations. In contrast, both the plasma and various organs of the diabetic rats contained only trace amounts of AG. The whole body perfusion of control rats depleted AG from most of the organs, the exception being spleen, the circulation system of which is known to have a structure that is difficult wash by means of perfusion. These observations indicated that AG readily diffused into the inter- and intra-cellular water spaces from the circulation. Accordingly, the plasma membranes of the cells in these organs were suggested to be permeable to AG.
