THE OBSERVATION OF THE FAT LABELLED IN PRELYMPHATIC PATHWAY IN INTESTINE OF RAT / 解剖学报

Objective To study the prelymphatic pathway in intestine. Methods Sudan black B was used to label fat which was fed to rats, then the pathway by which fat got into lacteals was observed under light and electron microscope. Results Under light microscope, we saw the blue\|greenish fat in epithelia, between epithelia, in lacteals and in the interstitial space around the lacteals. Under electron microscope, the pellets existed in epithelia, interstitial space and lacteals. Conclusion Fat might get into lacteals through the epithelia and the interstitial space which might be regarded as prelymphatic pathway. [
