Tissue concentration differences during active transport of calcium by intestine

Abstract

The APS Journal Legacy Content is the corpus of 100 years of historical scientific research from the American Physiological Society research journals. This package goes back to the first issue of each of the APS journals including the American Journal of Physiology, first published in 1898. The full text scanned images of the printed pages are easily searchable. Downloads quickly in PDF format.

The Influence of Verapamil on Calcium Transport and Uptake in Segments of Rat Intestine

“…Further study will be necessary to define the exact mechanism of action of ver apamil on calcium transport in intestinal tis sue. However, the results of this study appear to be consistent with the proposed two-step model of calcium transport in rat intestine [14], It is interesting that the other calcium an tagonist drugs examined in this study did not alter calcium transport or tissue uptake ( fig. 4).…”

Kinetics of Intestinal Calcium Transport during Maturation in Rats

“…The abdominal cavity was opened and the duodenal and jejunal segments were removed by stripping them from the mesentery. The intestinal segments were washed with cold 0.9% saline ( n = [11][12][13][14][15] solution and everted over polyethylene tubing. The everted gut sacs were suspended in 20 ml of a buffer solution which was oxygenated continuously.…”

Identification of an Intestinal Sodium and Calcium-Dependent Phosphatase Stimulated by Parathyroid Hormone

“…Received for publicationi 3 July 1973 and in revised form 15 February 1974. calcium across the basal-lateral membrane of the epithelial cell (1). This step requires sodium (2) but is independent of net sodium flux and is not inhibited by inhibitors of the Na, K-exchange pump (2)(3)(4).…”
