During a 23 year period at Memorial Hospital, the diagnosis of liver cell carcinoma was made in 42 patients who were 11 to 40 years old. Ninety per cent were Caucasian, mostly born in the United states. No occupational hazard was detected. Serum hepatitis antigen was demonstrated in only one patient. Alpha fetoprotein was found in the serum of 55 per cent of nine patients tested. Eight-three per cent were Rh positive, 43 per cent were ABO groups, A or O, respectively. Twenty-three per cent of 13 patients with sufficient material for study had an associated cirrhosis. Of these, active hepatitis with cirrhosis was present in one patient; postnecrotic cirrhosis was present in another. Approximately 7 per cent had a history of previous liver disease. One patient had infectious mononucleosis, and nearly 13 per cent gave a family history of cancer. Weight loss or pain in the right upper abdominal quadrant was present in 65 per cent, and hepatomegaly was found in 88 per cent. Only one patient presented with hemoperitoneum simulating an acute condition within abdomen. The liver profile examinations characteristically revealed an elevation in serum alkaline phosphatase, 5 nucleotidase, and Bromsulphalein retention with normal bilirubin level. The most common finding, upon roentgenographic examination, was an elevated right hemidiaphragm. Selective celiac and superior mesenteric angiography and 99mTc sulfur colloid liver scans were both done in 13 patients. There was a 75 per cent accuracy rate in localization of the tumor. At laparotomy, the tumor was found to be confined to one lobe in seven patients and involved both lobes in ten. Twenty-seven patients were thought to have multicentric tumors and 15 unicentric lesions. Only ten were found to be candidates for hepatic lobectomy. Five and ten years survival rates were 20 per cent; the operative mortality rate was 40 per cent. Twenty per cent died within a year, ten per cent, one patient, is alive with disease at 28 months and another is free of disease at 31-months. Paraneoplastic syndromes were erythrocytosis in two patients, terminal stage of hypoglycemia in one patient, and hypocholesterolemia with associated excess beta globulin in one patient.

Erythrocyte and serum enzyme system in the Gagu of the Ivory Coast have been investigated. Some systems (e.g. PGM) differ little between the subdivisions of the Gagu group, but others differ considerably (e.g. G6PD variants). In general the red cell enzyme frequencies fall within the range of variation characteristic of African populations. Serum cholinesterase variants are present only at low frequency, and the distribution of alkaline phosphatase phenotype shows the expected correlation with ABO blood groups.

An unselected series of 285 patients with Paget's disease of bone has been studied, of whom 54% were male and 46% female. The youngest was aged 25 years at diagnosis and the oldest 95. Of the patients 109 (38-2%) had never suffered serious symptoms. These diagnosed cases certainly represent only a small proportion, perhaps 10-15%, of all those with Paget's disease in the community from which they came. Few of the undiagnosed cases are likely to be suffering from serious symptoms or complications so it is apparent that the majority (probably over 80 or 90%) of those with the pathological state are relatively untroubled by their disease. The most common complication (8-8%) was pathological fracture. The fracture involved the shaft of the femur in 62% occurring in this section of the bone almost seven times more frequently in the patients with Paget's disease than in the general population. Because of the large number of undiagnosed cases in the community, the true incidence of pathological fracture and of sarcoma of bone in all patients with Paget's disease is probably only 1% and 0-1% respectively. Simultaneous estimates of the serum alkaline phosphatase and ESR were made in 128 of the patients. It was shown that the ESR is valueless as a measure of activity or extent of the disease. In many patients the level of the serum alkaline phosphatase changed very little over periods of several years. A history of the disease in one or more close relatives was found in three families, a lower incidence than was expected from previously recorded studies. The ABO blood groups were determined in 215 of the patients; 50% were of group A compared with 46% in a control group. The difference in distribution of blood groups in the two series of subjects is small and well within chance limits. The secretor status of 138 patients was investigated; 77% were secretors. This is similar to the proportion in control series. There is evidence to suggest that the degree of severity of Paget's disease does not vary, once it has developed in any particular individual, and that the more severe and extensive forms may have a stronger genetic basis.

In 260 normal students, 20-25 years old, the variation in the activities of serum alkaline phosphatase and its isoenzymes with sex, ABO blood groups, and protein intake were studied. The values are on the whole higher in males than in females. The activity of the intestinal isoenzyme was higher in subjects taking protein-rich diet than in those taking protein poor diet.

By use of sensitive immunocatalytic assays, based on isozyme specific monoclonal antibodies, the activities of the three main human alkaline phosphatases were determined in serum. The activities were related to ABO blood groups and secretor phenotypes. The activity of intestinal alkaline phosphatase was found to be strongly correlated with ABO blood groups and secretor phenotypes, while neither the placenta alkaline phosphatase activity nor the tissue unspecific alkaline phosphatase activity demonstrated any dependence on blood groups or secretor phenotypes. Non-secretors, independent of ABO blood groups, demonstrated low activities of intestinal alkaline phosphatase in serum, amounting to approximately 20% of the activities in the secretor groups. Within the secretor group, the lowest activities were observed for blood group A (2.8 +/- 1.1 IU/l; mean +/- SEM) and the highest for blood groups B and O (14.1 +/- 1.1 IU/l and 19.0 +/- 2.5 IU/l, respectively). These results confirm that the activities of intestinal alkaline phosphatase in serum have to be related both to ABO blood groups and to secretor phenotypes in order to be informative in clinical contexts.

Since November 1987, a total of 16 dialysis patients in the authors' Center, received a cryopreserved saphenous vein allograft (CSVA) as "third choice" vascular access. ABO and HLA-A-B compatibilities were determined but not considered. Saphenous veins were cryopreserved in liquid nitrogen for variable periods (1-6 mo), so that there was the opportunity to choose the most suitable in dimension. In February, 1989, a total of 13 patients retained a well-functioning access site, whereas three had died from causes unrelated to CSVA. Because rejection of venous allografts still is debated among angiologists, recipient T lymphocyte subsets (CD3-CD4-CD8 and CD4/8) were examined, as were lymphocytotoxic antibodies, before and on days 15 and 30 after implantation. No evidence of immunologic activation was found. Moreover, in 10 of 16 patients the surgeons subcutaneously implanted a fragment of CSVA, and an immunohistochemical study was carried out using an alkaline phosphatase-antialkaline phosphatase (APAAP) technique and a panel of monoclonal antibodies. Minimal infiltration of the outer layer of adventitia was found, mainly caused by monocyte macrophages (Leu M3+) with few T lymphocytes (CD3+). The authors conclude that rejection is not a major cause of failure in CSVA in dialysis patients.

The genetic structure of two Chukot Evens subpopulations (314 individuals) for electrophoretic protein systems and taste sensitivity to PTC was studied. 17 of the 39 loci were polymorphic (43.59%). The following systems were completely monomorphic: diaphorase NAD H (Dia); glucose-6-phosphate dehydrogenase (G-6-PD); glutamatoxalate transaminase (GOT); carbonic anhydrase (Ca-1); catalase (Ct), lactate dehydrogenase (loci LDH-A and LDH-B); leucine aminopeptidase (Lap); malate dehydrogenase (MDH); purine nucleoside phosphorylase (PNP); superoxide phosphorylase (PNP); superoxide dismutase (SOD); phosphoglucomutase-2 (PGM2); cholinesterase (locus E1); red cell esterase (4 loci); albumin (Alb); hemoglobin (Hb A and B); ceruloplasmin (Cp); and blood, gren, using the standard method. The following systems were polymorphic: red cell acid phosphatase (AcP); phosphoglucomutase-1 (PGM1); 6-phosphogluconate dehydrogenase (PGD); glutamatepyruvate transaminase (GPT); glyoxalase-1 (GLO-1); esterase (EsD); adenilatkinase (AK); alkaline phosphatase (Pp); cholinesterase (locus E2); haptoglobin (Hp); transferrin (Tf); group-specific component (Gc) and ABO, MN, Lewis, P blood groups and taste sensitivity to PTC. The following allele frequencies for polymorphic loci have been detected: AKI = 0.994; GLO = 1I = 0.082; GPT1 = 0.653; AcPA = 0.400; AcPB = 0.599; AcPC = 0.001; PGDA = 0.944; PGM1(1) = 0.906; EsD1 = 0.897; E2+ = 0.048; HpI = 0.394; GcI = 0,919; Tfc = 0.987; r(O) = 0.669; p(A) = 0.184; q(B) = 0.146; M = 0.711; Le = 0.411; P1+ = 0.521; t = 0.295. The genetic structure of Chukot Evens population is significantly nearer to that of the other ethnic groups of the North-East, in comparison with the genetic structure of Evenks of the Middle Siberia.

A series of 150 patients with serum hepatitis were examined for the incidence of the Australia antigen (HBsAg) and associations with ABO blood groups, haptoglobin types and occurrence of intestinal serum alkaline phosphatase. Among the patients studied 11.3% were positive for HBsAg. When compared to controls patients with blood group O showed a significantly increased risk for serum hepatitis (p less than 0.05), while those with group B showed a decreased risk (p less than 0.01). The presence of the intestinal fraction of alkaline phosphatase showed a negative association with serum hepatitis (p less than 0.01) and there was no significant association between alkaline phosphatase types and ABO groups among the patients. The frequency of the Hp1 gene was significantly increased (p less than 0.01) among the patients as compared to controls.

458 unrelated healthy women at various gestational ages were examined for serum heat-stable alkaline phosphatase (HSALP) activity. The sample was subdivided into four groups according to the compatibility mating type in the ABO and Rh systems: double compatible, ABO incompatible, Rh incompatible and double incompatible. The results confirm the exponential growth of serum placental isoenzyme as a function of gestational age and show that the moment of appearance of the placental isoenzyme is six weeks earlier in double incompatible matings.

Reference intervals of the activity of serum alkaline phosphatase isozymes (AP-IZ: high molecular-, liver-, bone- and intestinal-types) were determined according to the ABO (blood type) system in 200 healthy subjects aged 20-39 years. AP activity was determined according to the JSCC method. AP-IZ was stained by the formazan method after isolation by TITANIII-Lipo plate electrophoresis. For the electrophoresis, treated serum with neuraminidase and untreated one were concomitantly used for detecting liver AP and bone AP respectively. As a result of comparison of mean AP-IZ activity among the groups divided according to the ABO system, total AP, intestinal AP and liver AP activities in the type B and O persons were significantly higher than in the type A and AB persons. It is well known that the activities of total AP and intestinal AP in type B and O persons are higher than in type A and AB persons, but there have been no reports showing that the activity of liver AP in type B and O persons is higher than in type A and AB persons. Furthermore, in the type B and O persons there was a low correlation (r = 0.195, p < 0.05) between the activities of liver AP and intestinal AP. The present assessment included subjects in the age group (20-39 years) considered not to show fluctuations in the activity of bone AP, which is influenced by age. The above findings should be investigated in regard to other age groups.
