The Ultrastructural Localization of Acid Mucopolysaccharides in The Intestine after Irradiation

Subcellular localization of acid mucopolysaccharide (AMPS) was only slightly discernible in normal rat intestinal absorptive cells. Immediately after 1000 R of whole-body X-irradiation the Golgi complex of the absorptive cell possessed AMPS, but the thin enteric surface coat did not. At 5 hours afte...

Description
Summary:Subcellular localization of acid mucopolysaccharide (AMPS) was only slightly discernible in normal rat intestinal absorptive cells. Immediately after 1000 R of whole-body X-irradiation the Golgi complex of the absorptive cell possessed AMPS, but the thin enteric surface coat did not. At 5 hours after exposure the Golgi complex was lightly stained and a thick, AMPS-rich surface coat was present. These observations sugest that the Golgi complex participates in the final synthesis of AMPS that becomes a component of the enteric surface coat.
