The levels of serum gamma-glutamyl transpeptidase (GGT) and, when appropriate, alkaline phosphatase (AP) and 5'-nucleotidase (NTD) have been measured as a routine in 276 patients with malignant haematological diseases during a 26-month trial period. GGT levels add no prognostic information to the routine haematological surveillance of leukaemia. Polychemotherapy does not appear to be an inducer of liver drug-metabolising microsomal enzymes. Polycythaemia rubra vera, myelofibrosis and chronic lymphocytic leukaemia may cause little change in GGT, AP and NTD levels despite marked hepatomegaly. A raised GGT in Hodgkin's disease and non-Hodgkin lymphoma is generally associated with active and widespread disease, but not necessarily a sign of malignant tissue in the liver. The elevations of GGT in myeloma may be secondary to liver infiltration though this group merits further detailed study.

Intensive care patients receiving prolonged total parenteral nutrition (TPN) developed alterations of liver function tests, seen in the activity of certain serum enzymes. Hepatomegaly and jaundice sometimes appeared. The changes in chemical pathology were in serum transaminases activity (GOT, GPT, GDH); alkaline phosphatase and gamma-glutamyltranspeptidase as indices of cholestasis; lactate dehydrogenase, hydroxybutyrate dehydrogenase and creatine phosphokinase, as enzymes related to energy metabolism; pseudocholinesterase, as a protein metabolism-related enzyme. The possible causes of these alterations in critically ill patients undergoing TPN are considered and a functional final metabolic interpretation is proposed.

2-Deoxy-D-galactose, in a dose of 3 mmol/kg, was administered intraperitoneally twice daily to young rats for periods up to 12 weeks. This dosage schedule resulted in recurrent phosphate trapping predominantly in liver. UTP deficiency was excluded by simultaneous uridine injections. Phosphate trapping was caused by the rapid accumulation of 2-deoxy-D-galactose 1-phosphate and was most pronounced in liver but also demonstrated in small intestine, brain, spleen, and thymus. The marked, although transient, drop in the hepatic content of inorganic phosphate triggered the catabolism of adenine nucleotides and a loss of ATP. Other metabolic pathways affected by phosphate deficiency include glycogenolysis and glycolysis. Increasing with time, repeated doses of the galactose analog led to retardation and arrest of growth, hepatomegaly, and splenomegaly. The average relative liver and spleen weights were elevated 2.5- and 4.5-fold, respectively, after 12 weeks of treatment. Liver damage was indicated by hyperbilirubinaemia and a progressive rise in the activity in plasma of sorbitol dehydrogenase, alkaline phosphatase, and gamma-glutamyltransferase. Examination by light and electron microscopy showed increasing numbers of vacuoles, surrounded by a single membrane, in hepatocytes, sinusoidal endothelial cells, and Kupffer cells. Focal cytoplasmic degeneration in hepatocytes was occasionally indicated by formation of autophagic vacuoles and finger print lysosomes. Hepatocytes of 2-deoxy-D-galactose-treated rats showed a dissociation and fragmentation of the rough endoplasmic reticulum. Sinusoidal endothelial cells and Kupffer cells were markedly enlarged, the latter contained a PAS-positive but amylase resistant substance. Extrahepatic changes included an increased occurrence of vacuolated cells in thymus. Phosphate trapping and its metabolic consequences are common phenomena in the experimental injury induced b 2-deoxy-D-galactose and in some hereditary diseases such as uridylyltransferase deficiency galactosaemia, fructose intolerance and glucose-6-phosphatase deficiency.

The clinical course of 40 patients with histologically proven hepatocellular carcinoma was reviewed. The majority had symptoms and signs suggesting abdominal malignancy; these included abdominal pain, weight loss, tenderness in the right upper quadrant, hepatomegaly, and fever. The most useful diagnostic tests were determination of serum alkaline phosphatase level, sodium sulfobromophthalein (Bromsulphalein) excretion, and liver scan. Prothrombin time and bilirubin levels were normal or only slightly elevated. Celiac angiography was helpful in determining the extent of the disease. Surgical exploration was done in 25% of the cases, but in only 5% was resection attempted. The grim prognosis is indicated by the fact that only 10% of patients were alive six months after admission to the hospital.

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.

Fifty consecutive patients with blastic chronic myelogenous leukemia were evaluated clinically, morphologically, biochemically, and therapeutically. Forty-five patients had a preceding stable phase (38 Ph'+, 7 Ph'-); five patients presented with de novo Ph+ blast crisis. The most frequent clinical signs of impending blast crisis were weakness, fatigue, increasing splenomegaly, anemia, thrombocytopenia, marrow fibrosis, and a rising neutrophil alkaline phosphatase. Fever (unrelated to infection), skin infiltration, lymphadenopathy, hepatomegaly, thrombocytosis, and basophilia were much less common. The development of aneuploidy occurred in less than one-half of the total group. Myeloblastic morphology at blastic transformation was most frequent with occasional lymphoblastic, promyelocytic, and undifferentiated cases seen. Terminal deoxynucleotidyl transferase was present in one-third of the patients, but had no clear-cut relationship to the morphology. Response to treatment was generally disappointing (two complete and 15 partial remissions in 45 treated patients).

Hepatic function of 80 children aged under 3 years with Plasmodium vivax malaria were studied during the acute attack and 6 weeks after antimalarial treatment. Raised levels of serum aspartate transaminase (serum AST; SGOT), serum alanine transaminase (serum ALT; SGPT), and alkaline phosphatase were observed in 68%, 39% and 46% of cases respectively. AST levels were higher than ALT ones and the mean level of both enzymes was much higher in patients with hepatomegaly. The hepatic dysfunction which these observations reflect is transient, as these enzymes were found to be at their normal levels 6 weeks after treatment. A transient derangement of liver function is thus a common feature of childhood malaria, and hepatic dysfunction takes place to a significant degree even in P. vivax malaria.

In 71 patients with lymphogranulomatosis (35 males and 36 females aged from 19 to 67 years) the hepatic function was studied prior to and during the cytostatic treatment. There were found considerable disturbances in the liver functioning and parallelism between the activity of the mentioned enzymes and the presence of intoxication, the enlarged liver size and intensity of the pathological process. During the treatment in some patients the activity of the enzymes under study was decreased or normalized. Changes in the activity of blood transminase, aldolase and alkaline phosphatase would reflect the gravity of destructive processes and disturbances in the liver function in patients with lymphogranulomatosis. The data obtained are of certain value for the treatment and prognosis of the disease.

The results of liver, bone, and brain scans in 84 patients with recurrent or metastatic malignant melanoma were reviewed. The liver scan was initially positive in 18% (14/78) and ultimately in 32% (25/78). Serum alkaline phosphatase and lactic dehydrogenase were elevated in 92%. These patients ultimately developed positive liver scans, while convincing hepatomegaly was noted in only 44%. Bone scans were eventually positive in 33% (16/49), all of whom had pain. Brain scans were positive in 15% (10/65), all of whom had CNS symptoms. In asymptomatic patients, bone and brain scans only rarely disclosed occult lesions.
