Observations on Intestinal Obstruction Following the Intravenous Injection of Particulate Material.

Abstract

have previously failed to elicit toxic effects in transfusing normal dogs with systemic blood f rom dogs with intestinal obstruction. Wangensteen and Loucks6 were unable to detect evidence of histamine absorption when histamine dichloride was placed in the obstructed bowel. It is a significant fact that in the experiments reported here that portal blood of dogs dying of intestinal obstruction failed to exhibit the physiologic test for histamine; the addition of 10 mg. of histamine dichloride, however, produced immediate and protracted depression of blood pressure. 5058

“…Wangensteen and Cooke (51) conducted work wherein the reticulo-eiidothelial system of the rabbit was partially blocked in its phagocytic activity by daily intravenous injections of colloidal graphite.…”
