Animal Feed Additive and the Effect of the Fusarium Toxin Deoxynivalenol on the Electrophysiological Measurement of Transepithelial Ion Transport of Young Chickens with Ussing Chamber Technique
The presence of mycotoxins in poultry feeds is a significant factor for financial losses to animal industries. Ingestion of mycotoxin-contaminated feed by chickens causes injury to the gastrointestinal tract. DON has negative effects on the active transport of some nutrients in the small intestine of chickens. We tested the hypothesis that prefeeding with probiotic (Eubacterium sp.) or inulin, ...
متن کاملModulators of Ion Transport in Nasal Polyps: An in situ Measurement of Short-Circuit Current
OBJECTIVES To examine possible modulators of the ion transport through the apical membrane of the nasal polyps. METHODS The study was conducted using the freshly-excised nasal polyps from the patients with chronic sinusitis. A voltage-sensitive vibrating probe technique was introduced to monitor the short-circuit current across the apical membrane of the polyp at 37°C. RESULTS In the presen...
متن کاملMeasurement of short-circuit current and ion transport across the ileum1
CLARKSON, T. W., AND S. R. TOOLE. Measurement of shortcircuit current and ion transport across the ileum. Am. J. Physiol. 206(3) : 658-668. 1964. -An apparatus is described which allowed control over both the electrical and chemical potential gradients across the isolated ileum of the rat and at the same time permitted the measurement of the transport of ions and water. Silver ions, released fr...
متن کاملUssing's “Little Chamber”: 60 Years+ Old and Counting
Generally, a Commentary for the Frontiers in Physiology is aimed at a recent research article that has the potential to make a major impact on a particular scientific research field. However, where would the field of epithelial ion transport physiology be without the Ussing chamber? One has to ask that question in the 100th anniversary year of the birth of the great Danish physiologist Hans Hen...
متن کاملTransepithelial Transport of PAMAM Dendrimers across Isolated Rat Jejunal Mucosae in Ussing Chambers
Oral delivery remains a challenge for poorly permeable hydrophilic macromolecules. Poly(amido amine) (PAMAM) dendrimers have shown potential for their possible oral delivery. Transepithelial transport of carboxyl-terminated G3.5 and amine-terminated G4 PAMAM dendrimers was assessed using isolated rat jejunal mucosae mounted in Ussing chambers. The 1 mM FITC-labeled dendrimers were added to the ...
