Rats with portacaval shunts and humans with hepatic encephalopathy show severe myo-inositol depletion in the brain. The portacaval-shunted rat may therefore be a useful model for the investigation of neurochemical pathways containing myoinositol, which are modulated not only in hepatic encephalopathy but also in diabetes mellitus and Alzheimer's disease.

A specific radioimmunoassay method for rat erythrocyte carbonic anhydrases I and II was developed using a double antibody system. Its sensitivity was in the nanogram range for each of the two isozymes. The method has been applied to the assay of cerebral carbonic anhydrase. Only CAII has been found in brain extracts of perfused rats. Accordingly, the assay of CAI in cerebral tissue can be used to quantify erythrocyte contamination on condition that the ratio CAII/CAI in blood had been worked out. The developmental change in the soluble and the Triton X-100 solubilized brain CAII from birth to adult is reported.

By affinity chromatography the isozymic distribution of carbonic anhydrase (carbonate hydro-lyase, EC 4.2.1.1) has been studied in extract from various bovine tissues. Carbonic anhydrase II forms isolated from erythrocyte, kidney and brain are indistinguishable by specific activity, amino acid composition, fingerprint, electrophoretic and immunological behaviour. By these criteria they differ from carbonic anhydrase I isolated from rumen epithelium.
