Abstract
Summary
1. A colloid sol of hexabromostearic acid was used successfully for hepatosplenography in the rat. This sol could be given intravenously or by repeated intragastric injections. Dibromindigo appeared in the urine after intragastric injection. 2. Half the minimum intravenous dose of several halogenated fat emulsions for hepatosplenography was effective when reinforced with injections by the intralymphatic and intragastric routes, but the total dose was greater than the minimum intravenous dose alone. 3. The emulsions were broken by boiling but this method of sterilization was not necessary since it was found that the halogens acted as sterilizing agents.
