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.

The effect of prolonged normothermic ischaemia before partial hepatectomy was assessed in 10 dogs. During the period of ischaemia, portal decompression was maintained. The survival rate for animals undergoing 75 minutes of total liver ischaemia was 60 per cent and 2 of the dogs died as a result of hypoglycaemia. High levels of alkaline phosphatase and transaminases in the survivors indicated a severe degree of hepatocyte damage. However, complete restoration of liver mass was noted 6 weeks after partial hepatectomy and was not impaired by the prolonged ischaemia. This study confirms the resistance of the dog liver to ischaemia before partial hepatectomy. The critical period beyond which ischaemia is followed by an increasing number of deaths and severe metabolic upset is in the region of 1 hours.

Plasma glucose and lactate concentrations and glutamate-pyruvate transaminase (SGPT), glutamate-oxalacetic transaminase (SGOT), alkaline phosphatase (AP), aldolase (ALD), creatine phosphokinase (CPK), and hydroxybutyrate dehydrogenase (HBD) activities were determined before, throughout the incubation period, and during the course of a viral-induced diarrhea in the neonatal calf. Hypoglycemia with a glucose concentration less than 40 mg/dl of plasma was observed in 3 of 10 calves. Plasma lactate concentration increased to 1.84 plus or minus 0.1 times normal in 7 and 6 to 7 times normal in 2 of the animals. The major change in both glucose and lactate concentrations during diarrhea occurred during the 24 hours preceding death. Changes in SGPT, SGOT, or AP activities were not observed, indicating the absence of marked hepatic damage. The ALD, CPK, and HBD activities were increased in 2 calves and the CPK alone was increased in 2 others, indicating cardiac and possibly skeletal muscle damage.

In glycogen storage disease type III (glycogen debranching enzyme (DE) deficiency), the activities of serum alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase may be strikingly elevated during childhood but are low during adult life. To determine the pattern of the elevated serum enzyme activities in relationship to diet, the biochemical subtype and clinical symptoms, 13 patients with DE deficiency were studied. Activities of serum aspartate and alanine transaminases, lactate dehydrogenase, and alkaline phosphatase were markedly elevated during infancy. Continued elevation of enzyme activities during childhood appeared to be related to DE deficiency in liver, but unrelated to DE deficiency in muscle. Activity elevations correlated inconsistently with diet and poorly with childhood growth rate or the presence of hypoglycaemia. The serum enzyme activities declined around puberty concomitantly with a decrease in liver size. Although periportal fibrosis and micronodular cirrhosis indicated the presence of hepatocellular damage during childhood, the decline in serum enzyme activities with age and the absence of overt hepatic dysfunction suggest that the fibrotic process may not always progress.

The respiratory, renal, hematologic, and serum biochemical effects of hypertonic saline solution (HSS) treatment were examined in 12 endotoxic, pentobarbital-anesthetized calves (8 to 20 days old). Escherichia coli endotoxin (055:B5) was infused IV at a rate of 0.1 microgram/kg of body weight over 30 minutes. Endotoxin induced severe respiratory effects, with marked hypoxemia and increases in arterial-alveolar O2 gradient (P[A-a]O2), physiologic shunt fraction (Qs/Qt), and physiologic dead space to tidal volume ratio (Vd/Vt). Oxygen consumption was decreased, despite an increase in the systemic O2 extraction ratio. Peak effects were observed at the end of endotoxin infusion. The renal response to endotoxemia was characterized by a decrease in free-water reabsorption and osmotic clearance, as well as a decrease in sodium and phosphorus excretion. Endotoxemia induced leukopenia, thrombocytopenia, hyperphosphatemia, hypoglycemia, acidemia, and increased serum alkaline phosphatase concentrations. Calves were treated with HSS (2,400 mosm/L of NaCl, 4 ml/kg, n = 4) or an equivalent sodium load of isotonic saline solution (ISS; 300 mosm/L of NaCl, 32 ml/kg, n = 4 90 minutes after the end of endotoxin administration. Both solutions were infused over a 4- to 6-minute period. A control group (n = 4) was not treated. Infusion of HSS or ISS failed to induce a significant change in Pao2, P(A-a)O2, (Qs/Qt), (Vd/Vt), or oxygen consumption. Both solutions increased systemic oxygen delivery to above pre-endotoxin values. Hypertonic saline infusion induced significant (P less than 0.05) increases in serum Na and Cl concentrations and osmolality, whereas ISS induced a significant increase in serum Cl concentration and a significant decrease in serum phosphorus concentration.(ABSTRACT TRUNCATED AT 250 WORDS)

Abdominal eumycotic mycetoma caused by Pseudallescheria boydii was diagnosed in a 3-year-old male Siberian Husky. The dog was examined because of weight loss and signs of depression. Initially, pyrexia was the only clinical finding. Antibiotic and corticosteroid treatment was ineffective. Two weeks later, the dog's appetite had decreased, it had vomited a few times, and the caudal portion of the abdomen was sensitive to palpation. Hematologic and serum biochemical abnormalities consisted of anemia, leukocytosis, hypoglycemia, hypoalbuminemia, hyperglobulinemia, and high alkaline phosphatase activity. One week later, the dog's condition continued to worsen, and testicular swelling was observed. The dog was castrated. Microscopic examination of specimens obtained at surgery revealed pyogranulomatous periorchitis with mycetoma granules. Ketoconazole treatment was initiated and continued until the dog died one month later. Necropsy revealed multifocal duodenal ulcers, with transmural pyogranulomatous enteritis, pancreatitis, and peritonitis. This case is unique because the etiologic agent apparently entered via the intestinal tract rather than by contamination of an external wound.

Gram-negative septicemia/endotoxemia remains a serious clinical disorder that is often complicated by disseminated intravascular coagulation (DIC). Plasma antithrombin-III (AT-III) levels usually decrease during gram-negative septicemia/endotoxemia, and even moderate decreases in this major inhibitor of the coagulation system are associated with serious DIC. We demonstrated in an earlier study that prophylactic treatment of rats with 250 U/kg of AT-III followed by endotoxin challenge markedly attenuates DIC, indices of organ damage, and metabolic dysfunction. The present study was to determine whether treatment with 250 U/kg AT-III 1 hr after endotoxin challenge would be similarly efficacious. Rats treated with 250 U/kg of AT-III inactivated by human sputum elastase (ATX) served as protein controls. Blood samples for analysis were obtained 4 hr after AT-III or ATX treatment (5 hr after endotoxin challenge). Rats in the ATX treatment group exhibited abnormalities characteristic of endotoxemia, i.e., decreased fibrinogen levels and platelet counts, increases in prothrombin time and activated partial thromboplastin time, elevated serum glutamic oxaloacetic transaminase (SGOT) and alkaline phosphatase (AKP), and hypoglycemia. Treatment with AT-III markedly and significantly (P less than .05) attenuated all of these abnormalities, although survival was not increased. This study strongly suggests that supplementation of plasma AT-III is efficacious after the development of sepsis, although not as efficacious as prophylactic treatment.

Reversible endotoxic shock was induced in adult rats by i.v. injection of Escherichia coli O111:B4 lipopolysaccharide (1.6 mg/100 g). The shock progression was evaluated by measuring serum glucose levels as well as activities of aspartate aminotransferase (GOT) and alkaline phosphatase in serum. A rapid increase of serum glucose levels occurs, after LPS injection, followed by hypoglycaemia (minimum values at 6 h) with progressive reversion to control values. Serum GOT activity increased (twofold) 6 h after endotoxin administration and returned to control values at 72 h. No appreciable changes occurred in serum alkaline phosphatase activity. Endotoxaemia produced a decrease in the cytochrome P-450 levels in all target organs considered: lung, adrenal glands and liver. The progressive decrease in the serum albumin concentration as well as changes of the physical properties of the plasma membranes observed in vivo, can not be explained only by direct interaction of endotoxin with the target organs, underlining the importance of serum mediators in the induction of the shock response.

The metabolic effects of ethanol are due to a direct action of ethanol or its metabolites, changes in the redox state occurring during its metabolism, and modifications of the effects of ethanol by several nutritional factors. Ethanol causes hyperglycemia or hypoglycemia depending whether or not glycogen stores are adequate, inhibits protein synthesis, and results in a fatty liver and elevations in serum triglyceride levels. Increases in serum lactate, results from the increased reduced nicotinamide-adenine dinucleotide/nicotinamide-adenine dinucleotide + (NADH/NAD+) ratio, and hyperuricemia probably occurs owing to the increased turnover of adenine nucleotides after ethanol ingestion. Ethanol decreases thiamine absorption and decreases the enterohepatic circulation of folate. Acetaldehyde, the major metabolite of ethanol, increases the degradation of pyridoxal 5'-phosphate by displacing it from its binding protein and making it susceptible to hydrolysis by membrane-bound alkaline phosphatase. Chronic ethanol administration also results in decreased vitamin A stores and reduced bone mass and blood levels of 25-hydroxyvitamin D. The mechanism whereby ethanol affects these vitamins and their associated enzymes is unknown.

An earlier study by our group demonstrated significant amelioration of hypotension, hypoglycemia, and acidosis in dogs treated with purified human plasma fibronectin prior to induction of endotoxic shock. The present study was completed to determine whether treatment with purified human plasma fibronectin 1 hr after induction of endotoxic shock would provide similar benefits. To this end, selected hemodynamic, pulmonary, acid-base, metabolic, hematological, and serum chemistry parameters were monitored for 6 hours in two groups of anesthetized dogs in Escherichia coli endotoxic shock. One group was given an intravenous injection of purified human plasma fibronectin, and the other received an equal volume of saline 1 hr after shock induction. Between-group analysis of the data revealed no significant differences between any parameter excepting modest differences in plasma glucose, albumin, alkaline phosphatase, and BUN concentrations. However, even these differences, although statistically significant, were sporadic and unimpressive. This study suggested that treatment of dogs with fibronectin during gram-negative endotoxic shock was not efficacious.
