HISTOCHEMICAL STUDIES ENZYMES OF HUMAN HEPATOCELLUAR CARCINOMA AND ITS SURROUNDING LIVER TISSUES II.ALTERATIONS OF ALKALINE PHOSPHATASE, ACID PHOSPHATASE, 5 '-NUCLEOTSDASE, NON-SPECIFIC ESTERASE AND SUCCINIC DEHYDROGENASE
Zhan Rongzhou, et alDepartment of pathologic Anatomy
By histochemical methods of AKPase, ACPase, 5'-Nase, NSE and SDH, 10 cases of human hepatocellular carcinoma (HCC) and its surrounding liver tissue were investigated. Generally, these enzyme activities in HCCs obviously decreased or completely disappeared, neverthless in one case, the AKPase of HCC showed notable activity, and in another case, the ACPase activity also marked.The surrounding liver tissue either in cirrhosis or in hepatic fibrosis appeared normal hepatic enzymatic activity. The differences of enzymes between HCCs and their surrounding liver tissues were distinct.
