The presence of alpha-1-fetoprotein, the heat stable alkaline phosphatase and Australia antigen was examined in 103 patients with porphyria cutanea tarda, 300 patients with cirrhosis and 18 patients with primary liver carcinoma. The heat stable alkaline phosphatase was determined in 46 percent of patients with porphyria cutanea tarda and in 61 percent of patients with primary liver carcinoma. Alpha-1-fetoprotein was detected in 61 percent of patients with primary liver carcinoma and in 2 patients with porphyria cutanea tarda in whom primary liver carcinoma was proved later. The simultaneous occurrence of alpha-1-fetoprotein and the heat stable alkaline phosphatase was found in 50 percent of cases with primary liver carcinoma. Neither the patients with porphyria cutanea tarda nor the patients with cirrhosis were Australia-antigen positive. Australia-antigen could be detected only in one patient with alpha-1-fetoprotein positive-carcinoma of the liver.

Four patients with hepatocellular carcinoma had a variant alkaline phosphatase that resembles the placental D-variant but is different from it in electrophoretic mobility, pH optimum, heat stability, and inhibition by phosphate. The appearance of this enzyme has been specific to hepatocellular carcinoma. Its prevalence was about 30%, while that of another marker protein, alpha-fetoprotein was 77%. The occurrence of this enzyme in serum of patients with hepatoma was, accordingly, independent of the serum alpha-fetoprotein concentration, and also independent of the appearance of the Regan or the Nagao isoenzymes and of the serum alkaline phosphatase activity. Patients with the enzyme had a massive type of hepatocellular carcinoma with grade III differentiation by Edmondson's classification. The detection of this enzyme in serum may be of help in confirming the diagnosis of hepatoma.

Intestinal metaplasia is often associated with human gastric carcinoma. Intestinalization seems to be a typical example of abnormal differentiation and is possibly a precancerous state. For investigation of intestinal metaplasia, a method for visualizing disaccharidases using Tes-Tape was developed; this method was applied to many specimens of stomach surgically removed for the treatment of gastric carcinoma. More than 130 specimens of human stomach were investigated. Intestinalization was classified into types I and II intestinal metaplasia. In type I intestinal metaplasia, sucrase, maltase, trehalase, alkaline phosphatase, goblet cells, and Paneth cells were present; while the type II intestinal metaplasia, sucrase and maltase were present but alkaline phosphatase and trehalase were absent. In type II, goblet cells were present but not Paneth cells. The histochemical technique for sucrase was newly devised. Some of the villi with goblet cells in the area of intestinalization in the stomach were not stained by sucrase activity, although most of the villi were stained. The presence of a third type of metaplasia was suggested. Purified sucrases obtained from the intestine and one case of type I intestinal metaplasia showed blood group reactivity due to the oligosaccharide side chain. However, purified sucrases obtained from two cases of type II intestinal metaplasia were negative in blood group reactivity. A close relation between distribution of alpha-fetoprotein and carcinoembryonic antigen in gastric carcinoma and that in surrounding intestinal metaplasia is discussed.

Regan isoenzyme, variant alkaline phosphatase, and alpha-fetoprotein were found in the serum of a patient with gastric cancer. The histology of the tumor was tubular adenocarcinoma. There were metastases in the retroperitoneal lymph nodes, but not in the liver. The liver was normal microscopically, with no evidence of bile duct obstruction. alpha-Fetoprotein in the tumor tissue was detected by immunoprecipitation reaction in agar. Regan isoenzyme and variant alkaline phosphatase were also detected in the tumor tissue and total alkaline phosphatase activity of the tissue was very high. These findings suggested their tumor origin.

The clinical features of 57 autopsied cases of intrahepatic bile duct carcinoma including 28 cases of the peripheral type (cholangiocarcinoma in the narrow sense) and 29 cases of the hilar type are described in comparison with those of hepatocellular carcinoma, with a review of the literature on the clinicopathological aspects of intrahepatic bile duct carcinoma. As compared with hepatocellular carcinoma, the average age of the patients was older; the male predominance was not obvious, chronic parenchymal liver disease was infrequent in the past history, association of primary cirrhosis was seldom, cholestatic features were frequently the early signs and more pronounced during the course, the liver was enlarged to a lesser extent, ascites was less common, signs of portal hypertension were absent or minimal, and extrahepatic metastases were less frequent. In many respects, the hilar type resembled extrahepatic bile duct carcinoma, and the peripheral type was somewhat between it and hepatocellular carcinoma. Although the overall survival was not much different from that for hepatocellular carcinoma, early diagnosis is emphasized; this would make surgical management possible. Differential diagnosis from hepatocellular carcinoma may be possible in the majority with direct cholangiography, liver scan, celiac angiography, determination of alpha-fetoprotein and hepatitis B antigen, and blood chemistry such as SGOT, SLDH, serum bilirubin and alkaline phosphatase. Illustrative cases are given including one patient with a hilar carcinoma who survived for more than 2 years after transhepatic biliary drainage.

Carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), and carcinoplacental alkaline phosphatase (CPALP) were detected simultaneously in the sera and body fluids of two male patients with gastric carcinoma matestatic to the liver. At autopsy, widely disseminated gastric cancer of Borrmann III type with liver metastases was revealed in both bases. Histologically, they were moderately differentiated tubular and papillary adenocarcinomas with marked cellular atypia and necrosis. In Case 1, the properties of CPALP were identical to Nagao type CPALP, and in Case 2 the Variant type CPALP. Using immunofluorescence, CEA and CPALP were demonstrated in both primary and metastatic cells. However, only in Case 2 was AFP observed in some of the primary tumor cells.

Changes in maternal plasma proteins during pregnancy are now well documented. These changes may be quantitative, as seen in the electrophoretically separated fractions of serum and in the various binding globulins; or they may be represented by the appearance of a protein which is present only in the serum of pregnant women. These include the placental isoenzyme of alkaline phosphatase, oxytocinase, human chorionic gonadotropin and the "pregnancy-associated plasma proteins." Other constituents, such as alpha-fetoprotein, salivary amylase, prolactin and the proteins of the "pregnancy zone," which are present in small quantities in non-pregnant women as well as in men, show a substantial increase in concentration in the maternal circulation during pregnancy. An important factor in the etiology of protein changes is the effect of hormones, especially estrogen, on the synthesis and degradation of these proteins. While certain quantitative changes such as those seen in hormone binding proteins may interfere with diagnostic procedures, a number of pregnancy-associated changes in protein composition of the maternal circulation may be used to follow the course of pregnancy by monitoring placental function as well as fetal maturity and well being.

An enzyme-immunoassay for the quantitation of human alpha-fetoprotein was developed employing the so-called sandwich method using filter paper discs as a solid-phase. Filter paper discs were activated with cyanogen bromide and the specific antibody to alpha-fetoprotein was covalently bound to the discs. The enzyme-labeled antibody was prepared by coupling the antibody to alkaline phosphatase with the aid of glutaraldehyde. The antibody-coated filter paper discs were incubated with the samples containing alpha-fetoprotein, which was bound to the discs, then the discs were incubated with the enzyme-labeled antibody solution. The enzyme activity bound on the discs was then measured, and was found to be proportional to the amount of alpha-fetoprotein in the sample. The present method provided an accurate measurement for human alpha-fetoprotein in test serum in a range of 40 approximately 1,000 ng/ml. The sensitivity was almost comparable to that of radioimmunoassay. alpha-Fetoprotein levels in the normal and patient sera tested with this method were in good agreement with the values obtained by the radioimmunoassay technique.

Using rats, we studied how best to assess hepatic damage after administering therapeutic doses of each of five anti-cancer drugs or of the hepatotoxin, carbon tetrachloride. As indexes, we compared measurement of the concentration of administered antipyrine in plasma with measurement in serum of alpha-fetoprotein or of the activities of five enzymes that reportedly best reflect hepatic damage. The biological half-life of antipyrine in the plasma was increased more than threefold on pretreating the rats with any of the five cytotoxic drugs or with carbon tetrachloride. In contrast, the concentrations of alpha-fetoprotein, alkaline phosphatase, gamma-glutamyltransferase, or glutamate dehydrogenase were not consistently increased. Of the enzymes tested in serum, aspartate aminotransferase and ornithine carbamoyltransferase best indicated hepatic impairment resulting from the treatment with anti-cancer drugs. Our results imply that determination of the pharmacokinetics of marker drugs such as antipyrine better indicates hepatic dysfunction induced by cytotoxic agents than does measurement of the enzymes liberated into serum as a result of damage to liver mitochondria.

Two human endodermal sinus tumours (yolk sac tumours) were transplanted successfully into nude mice. The transplanted tumours maintained not only morphological characters, such as Schiller-Duval bodies, but also the ability to synthesise alpha-fetoprotein, lactic dehydrogenase 1, liver and bone type alkaline phosphatase, and some human serum proteins. Since these tumours produced lactic dehydrogenase 1 but not the other four isozymes of lactic dehydrogenase, this isozyme, like alpha-fetoprotein, seems to be a good marker for the diagnosis and management of cases of endodermal sinus tumour. One of the two tumours produced another fetal antigen or carcinoembryonic antigen in addition to alpha-fetoprotein. These two endodermal sinus tumours, with their various markers in nude mice, will be useful in studies on diagnostic markers.
