title: Effect of 25-hydroxyvitamin D3 on Na+-dependent D-glucose transport in rachitic rats.
abstract: We have previously reported that feeding rats on Steenbock and Black's rickets-inducing diet, deficient in vitamin D and with an altered Ca/P ratio, leads to metabolic consequences and a marked decrease of Na+-dependent D-glucose uptake at the jejunum-ileum level. To clarify the relationship between experimental rickets and D-glucose uptake, 25-hydroxyvitamin D3 (25-OH-D3) was given to rats fed on the rickets inducing diet. In the jejunum-ileum of these animals Na+-dependent D-glucose uptake returned to the values of the controls while the decrease in D-glucose uptake in the brush-border membrane vesicles prepared from kidney cortex of rachitic animals was not corrected by the administration of 25-OH-D3.
