In situ absorption of aflatoxins in rat small intestine.
To evaluate the rate at which the four main aflatoxins (aflatoxins B1, B2, G1 and G2) are able to cross the luminal membrane of the rat small intestine, a study about intestinal absorption kinetics of these mycotoxins has been made. In situ results obtained showed that the absorption of aflatoxins in rat small intestine is a very fast process that follows first-order kinetics, with an absorption rate constant (ka) of 5.84 +/- 0.05 (aflatoxin B1), 4.06 +/- 0.09 (aflatoxin B2), 2.09 +/- 0.03 (aflatoxin G1) and 1.58 +/- 0.04 (aflatoxin G2) h-1, respectively.
