The effect of purified human, rat, and hamster salivary kallikreins on microvessels of the rat mesentery and hamster retrobuccal pouch was studied by intravital microscopy. Dilatation of arterioles, a reduction in diameter of the venules, and an increase in the number of active capillaries were found. These effects differed depending on the species and organ concerned. Homogenates of the mesentery and retrobuccal pouch, proteins of the albumin type, histamine, and certain amino acids were found to activate the salivary kallikreins.
