[Interference of chloramphenicol with some cytoplasmatic enzyme systems].

The activity of alkaline phosphatase was determined in a lot of Wistar white rats which had received during 8 days therapeutical doses of chloramphenicol hemisuccinate, the enzyme being investigated in the circulating granulocytes and the liver. In the neutrophil granulocytes evidence was found of a marked decrease in alkaline phosphatase activity (40% presented a positive activity in the injected animals as against 70% in the controls). In the liver the histochemical test used did not allow for a discrimination between the experimental and control animals.
