Minireview on Regulation of Intestinal Calcium Absorption
An overview of current information on the mechanisms by which intestinal calcium absorption occurs is described in this article. Both paracellular and transcellular pathways are analyzed. Special emphasis focuses on molecules participating in the latter pathway, such as TRPV5 and TRPV6 channels, located in the apical region of the enterocytes, CB 9k and CB 28k , presumably involved in the catio...

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولDependence of oxalate absorption on the daily calcium intake.
Two to 20% of ingested oxalate is absorbed in the gastrointestinal tract of healthy humans with a daily 800 mg calcium intake. Calcium is the most potent modifier of the oxalate absorption. Although this has been found repeatedly, the exact correlation between calcium intake and oxalate absorption has not been assessed to date. Investigated was oxalate absorption in healthy volunteers applying ...
متن کاملButyrate Metabolism in the Lactating Cow S-
The possibility that butyrate may be glucogenic in ruminants has been suggested by several experimental studies. Intravenous injection of butyrate in sheep was followed by increased concentrations of blood sugar (1) and, in lambs, it was found that butyrate was more effective than propionate for alleviating insulin-induced hypoglycemia (2) ; acetate injection did not have a similar effect in ei...
متن کاملRecent developments in intestinal calcium absorption.
Calcium absorption proceeds by transcellular and paracellular flux, with the latter accounting for most absorbed calcium when calcium intake is adequate. Vitamin D helps regulate transcellular calcium transport by increasing calcium uptake via a luminal calcium channel and by inducing the cytosolic calcium transporting protein, calbindinD(9k). Recent studies utilizing knockout mice have challen...
