The intestinal absorption characteristics of anthraquinones emodin and chrysophanol were observed by measuring the intracellular accumulation across Caco-2 cells by the reverse-phase high performance liquid chromatography. The intracellular accumulation of chrysophanol was much greater than that of emodin, the maximum absorption of emodin and chrysophanol being 414.02+/-15.28 and 105.56+/-11.57...

18 Post-oral sugar actions enhance the intake of and preference for sugar-rich foods, a process 19 referred to as appetition. Here we investigated the role of intestinal sodium glucose co20 transporters (SGLTs) in sugar appetition in C57BL/6J mice using sugars and non-metabolizable 21 sugar analogs that differ in their affinity for SGLT1 and SGLT3. In Experiments 1 and 2 food22 restricted mice ...

The purpose of this study was to determine whether the sedentary dog is able to autoregulate glucose production (R(a)) in response to non-insulin-induced changes (<20 mg/dl) in arterial glucose. Dogs had catheters implanted >16 days before study. Protocols consisted of basal (-30 to 0 min) and bilateral renal arterial phloridzin infusion (0-180 min) periods. Somatostatin was infused, and glucag...

The implied existence of two mechanisms for glucose uptake into heterotrophic plant cells was investigated using the fluorescent glucose derivative 2-NBDG (2-(N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino)-2-deoxyglucose), two membrane impermeable fluorescent markers (3000 mol. wt. dextran-Texas Red (d-TR) and Alexa-488), hexose carrier and endocytic inhibitors (phloridzin and wortmannin-A, respec...
