[A histochemical method for detecting xanthine oxidase activity in the liver].
A histochemical method is described for localizing xanthine oxidase--the key enzyme in the purine catabolic pathway. The above method is based on the reduction of p-Nitroblue tetrazolium during hypoxanthine enzymatic oxidation, phenazine methosulfate being an intermediate electron acceptor. The patterns of the reaction product distribution suggest that the Kupffer cells and the sinusoidal endothelium possess the highest xanthine oxidase activity.
