Tissue Heparin and Mast Cells in Rats and Rabbits.

Abstract

Tissue heparin contents and mast cell counts were determined in liver, lung, intestine, kidney, spleen and thymus of male rats and rabbits. In most instances, distribution of heparin and mast cells did not follow the same pattern. Rat organs showed higher heparin values, but lower mast cell numbers than the corresponding rabbit tissues.
