title: Comments on spleen sinus enzyme equipment. A histochemical study.
abstract: Histochemical observations were made of the activities of nucleosidephosphatases splitting ATP, ADP, IDP, and AMP and exopeptidases splitting l-alanine, l-leucine and l-glycyl-proline in the spleen sinuses of man, mouse, rat, hamster, and rabbit. Of the exopeptidases, only glycylprolyl-naphthylamidase could be proved histochemically, and that only in man and rat. Nucleosidephosphatases showed only traces of activity except in the rabbit where there was highly active AMP-ase, the others being moderately active.
