Evaluation of chromic oxide, glycerol triether, and beta-sitosterol as fecal flow markers in two species of nonhuman primates.

abstract：:In experiments on dogs, i.v. administration of platelet-activating factor (PAF) (500 ng/kg) was shown to induce hypotension which, apart from decreased myocardial contractility, was characterized by blood pooling in veins (82.6 +/- 6.8 mL/kg). This was accompanied by restriction of venous return to the heart and reduc...
