Abstract
If Ringer's solution containing 1 per cent. goat serum is repeatedly perfused through the blood-free liver of a normal, anaphylactic or immune rabbit, no diminution in the amount of goat serum in the perfusion fluid is produced, that can be detected by titration with a specific precipitating serum.
If defibrinated normal, anaphylactic or immune rabbit blood is added to the perfusion fluid, diminutions in the amount of goat serum are observed after repeated liver passage; but in all cases these diminutions are identical with diminutions observed in control samples of the fluid kept at incubator temperature and not passed through the liver.
The perfusion experiments therefore furnish no evidence of the existence of a specific receptor apparatus (Ehrlich) for goat proteins, in normal, anaphylactic, or immune rabbit livers.
