Background and Objectives: calcium is the most abundant mineral in the body, making up nearly 2% of total body weight. This element has several roles in organisms. Manganese is an essential trace element which is taken part in the structure of some metal enzymes. There is a little evidence for deficiency of manganese in human, whereas its toxicity has been reported in several cases. Since, ca...
متن کاملTrigonella Foenum Gracum Seed Extract Inhibit Uptake of Glucose across Rat Everted Gut Sacs in Vitro
To investigate the absorption and the inhibition of glucose by the aqueous seed extracts of Trigonella foenum gracum. The small intestine of all animals were removed, washed with 0.9% (w/v) normal saline and intestinal segments were everted the empty sac was filled with 0.5 ml of the KHB buffer and placed in a stoppered conical flask with 5 ml of the buffer with varying concentration of glucose...
متن کاملEffect of manganese source on manganese absorption by the intestine of broilers.
Two experiments were conducted to investigate the effect of Mn source on Mn absorption by the intestine of broilers. In Experiment 1, the effect of Mn source, including MnSO(4), 2 Mn-amino acid chelates (Mn-Gly and Mn-Met) synthesized in our laboratory, 3 Mn-amino acid complexes with different complex strengths (Mn-Met E, Mn-AA A, and Mn-AA B), and 2 mixtures of MnSO(4) with Gly or Met, on Mn a...
متن کاملKinetics of manganese absorption in ligated small intestinal segments of broilers.
Two experiments were conducted with 28-day-old male commercial broilers to study mechanisms of Mn absorption and the effect of Mn treatment on divalent metal transporter 1 (DMT1) mRNA levels in ligated segments from different intestinal regions of broilers. The results from experiment 1 showed that the amount of Mn absorption was asymptotic with respect to time within 40 min after perfusion of ...
متن کاملPhenol red inhibits uptake of phosphate by the everted gut sacs of mice.
Uptake of phosphate by the everted intestinal sacs of mice was measured at various concentrations of this anion in the incubation medium. Phenol red when added to the serosal side was able to inhibit the uptake of phosphate significantly, while uptake of glucose or proline was unaffected. When para amino hippuric acid was present along with phenol red in the serosal compartment, the inhibition ...
