The absorption of plant sterols by the fowl.
I. A gas-liquid chromatographic method for the detection of phytosterols in tissues and excreta of birds was developed. The limitations of this method are discussed. 2. pand y-Sitosterol werc detected in the plasma of adult cockerels and in the plasma, intestinal wall, and liver of 4-week-old cockerels. The proportion of sitosterols in the total sterol absorbed appeared to be affected by the na...
متن کاملManganese absorption by excised barley roots.
Short-term absorption studies with 5-day-old excised barley roots revealed that the basic aspects of Mn absorption were similar to those of other metabolically absorbed cations. Following an initial non-metabolic equilibration with the root, Mn was absorbed for several hours at a slower steady-state rate comparable to that of other inorganic cations. Complete or nearly complete inhibition of th...
متن کاملPharmacokinetics of pulmonary manganese absorption: evidence for increased susceptibility to manganese loading in iron-deficient rats.
High levels of airborne manganese can be neurotoxic, yet little is known about absorption of this metal via the lungs. Intestinal manganese uptake is upregulated by iron deficiency and is thought to be mediated by divalent metal transporter 1 (DMT1), an iron-regulated factor known to play a role in dietary iron absorption. To better characterize metal absorption from the lungs to the blood and ...
متن کاملDose dependence of zinc and manganese absorption in man.
Intestinal absorption and excretion are the main regulatory mechanisms for maintenance of body homeostasis of most trace elements. In spite of considerable research on trace element metabolism in man and experimental animals, the knowledge about the mechanisms involved in these processes is still limited. The characteristics of trace element metabolism, such as low fractional absorption, the pr...
متن کاملEvaluation of Chemical Characteristics and Effects of Different Manganese Sources on Kinetics of Manganese Absorption and Performance of Broiler Chickens
Three experiments wereconducted to evaluate chemical characteristics, intestinal absorption and bioavailability of manganese(Mn)from organic, inorganic and nano sources of Mn. In experiment 1, inorganic sources of Mn including Mn-sulphate and Mn-oxide, organic sources of Mn as Mn-glycinate and Mn-bioplex and FRA® easy dry Mn as a nano source of Mn were subjected to elemental analysis and solubi...
