The value of the leucocyte adherence inhibition (LAI) test in the diagnosis of hepatocellular carcinoma (HCG) was investigated in 36 patients with this tumour. The sensitivity and specificity of the tube LAI test was assessed in 21 patients with HCC, 15 apparently healthy individuals, 9 patients with various forms of benign liver disease and 5 patients with non-hepatic neoplasms. In only 42% of the HCC patients tested was leucocyte adherence to glass reduced to a greater extent than in the healthy controls and in the patients with non-hepatic neoplasms, and the differences were not statistically significant. Moreover, positive results were obtained in 6/9 patients with benign hepatic disease. A further 15 patients were tested against extracts of HCC tissue using the haemacytometer LAI method. Of these, 53% gave positive results. In all, only 17/36 patients (47%) gave positive LAI responses. The test is thus of limited value in the diagnosis of HCC. The high false-negative result rate may be due either to abrogation of the immune response in HCC patients with large tumour burdens or to antigenic heterogeneity in HCC.

Serum 25-hydroxycholecalciferol (25-HCC) and serum parathyroid hormone (iPTH) were measured in 59 randomly selected adult epileptic outpatients receiving chronic anticonvulsant therapy. Quantitative morphometric analysis of iliac crest biopsies was performed. A mild degree of osteomalacia was found which was inversely correlated to dietary vitamin D intake. Serum 25-HCC was reduced in the epileptic patients compared to a control group, although dietary intake of vitamin D was higher than the mean daily intake in the Danish population. Serum 25-HCC was positively correlated to dietary vitamin D intake, but not correlated to the severity of bone changes, indicating that other factors than circulating 25-HCC are responsible for the development of anticonvulsant osteomalacia. Serum 25-HCG was inversely correlated to serum iPTH in patients with a low dietary calcium intake. The mean value of serum iPTH was not increased, and there was no correlation between serum iPTH and bone morphometry.

Using 109 hepatocellular carcinomas (HCG), 34 cholangiocellular carcinomas (CCC), 4 mixed hepatocellular-cholangiocellular carcinomas (MHC) and 24 metastatic adenocarcinomas in the liver (MA), an immunohistochemical study on primary carcinoma of the liver was performed by means of the ABC method for carcinoembryonic antigen (CEA), epithelial membrane antigen (EMA), tissue polypeptide antigen (TPA) and keratin. The material consisted of surgical specimens of Kosin Medical College including 50 HCC, 17 CCC and 1 MHC, surgical specimens of 20 HCC from the University of Occupational and Environmental Health, Japan (UOEH) and autopsied specimens from UOEH that included 39 HCC, 17 CCC, 3 MHC and 24 MA. All the specimens were fixed with 10-15% formalin and embedded in paraplast manually at Kosin Medical College and by utilizing an automatic embedding machine with a decompressing procedure at UOEH. The antigenicity of TPA and keratin was preserved better in the specimens of Kosin Medical College than in those from UOEH. It is therefore assumed that manually embedded specimens are superior to specimens embedded by using an embedding machine with regard to the preservation of some antigenicities. The immunoreactivity of the 4 antigens in CCC cells was significantly higher than that in HCC cells, and the intracellular localization of antigens generally showed several characteristics in HCC and CCC. However, as the same localization of antigens is also seen in both HCC cells and CCC cells, it is considered that the immunohistochemical examination using plural antibodies is not always useful for a differential diagnosis between HCC and CCC, which is difficult in conventional sections. That TPA in HCC may be an oncodevelopmental antigen is suggested by the facts that the higher the grade of HCC, the higher the immunoreactivity of HCC cells, that hepatocytes with possible higher activity sometimes showed a positive reaction in the present study and that TPA is expressed in fetal hepatocytes in a fetus up to 20 weeks in the literature.

The aflatoxin B1 content of liver tissue was measured in patients who died from chronic liver disease [hepatocellular carcinoma (HCG) (5), schistosomal liver fibrosis (1), chronic aggressive hepatitis (1)] and compared with fifteen controls who died of motor traffic accidents (10), drowning (1), malnutrition (1), idiopathic cardiomegaly (1) and lung infection (2). Significant levels of aflatoxin B1 were found in hepatocellular carcinoma patients who were also hepatitis B surface antigen (HBsAg) negative. Histology showed HCC arising in macronodular cirrhosis.
