The absorption of calcium from the intestine.
From studies of loss of radiocalcium from the intestinal lumen of rats it was well known that the absorption of calcium occurs mainly in the proximal small intestine (Harrison & Harrison, 195 I ; Nicolaysen, 195 I) . A similar observation was made in the pig (Moore & Tyler, 1955). In the chick, according to Coates & Holdsworth (1961), however, calcium absorption appeared to occur over the whole...

متن کاملAlcohol and absorption from the small intestine
Absorption of electrolytes from the intestinal lumen into the blood stream involves, predominantly, the process of active transport. Energy for cellular metabolism derives from the splitting of the high energy phosphate bond of adenosine triphosphate (ATP) by the enzyme adenosine triphosphatase (ATPase), (Brooks, 1973). Ethanol has been shown to affect the ATP content in several tissues and it ...
متن کاملAcute in vivo studies on glucose absorption from the small intestine of lambs, sheep and rats.
I . Rates of disappearance of glucose from ligated loops of small intestine in lambs, adult sheep and young rats were studied. The concentration of glucose in the lumen decreased exponentially with time, suggesting that within a range of concentrations of 166-277 m-moles/l glucose was absorbed mainly by passive diffusion. 2. The rate of absorption of glucose from a 166 mM-solution based on eith...
متن کاملEffect of 5-fluorouracil treatment on SN-38 absorption from intestine in rats.
5-Fluorouracil (5-FU)-based chemotherapies with irinotecan have been applied for the treatment of cancers, and a common dose-limiting toxicity is neutropenia and diarrhea. In this study, we investigated the effect of 5-FU treatment on expression levels of drug transporters for SN-38 transportation and SN-38 absorption from the intestine following 5-FU treatment. Expression levels of several dru...
