Very few patients with liver metastases from colorectal cancer can be cured. We have investigated whether a treatment to slow the growth of liver metastases, hepatic-artery infusion of floxuridine, improves palliation in this setting. In a randomised study of 100 patients, we compared quality of life and survival in patients who received hepatic-artery infusion of floxuridine and in those who received conventional symptom palliation. 95% of control patient survival time was spent with normal quality-of-life scores, which suggests that the aim of treatment should be to prolong normal-quality survival rather than merely to sustain quality of life. There was a significant prolongation (p = 0.03) in overall survival in floxuridine-treated patients compared with controls (median 405 vs 226 days). There were similar significant prolongations in normal-quality (ie, normal symptom scores) survival for physical symptoms (p = 0.04), anxiety (p = 0.04), and depression (p = 0.04). This survival benefit was associated with significant reductions in metastasis size on computed tomography (p = 0.001) and in serum carcinoembryonic antigen concentration (p = 0.006) in floxuridine-treated patients. There was no evidence of treatment-related hepatotoxicity as assessed by serum aspartate aminotransferase and bilirubin measurements. This is the first demonstration that survival can be prolonged with normal quality of life in patients with colorectal liver metastases. We conclude that hepatic-artery floxuridine infusion can be recommended for suitable patients.

The effects of aspartate (Asp) and 2-oxoglutarate (2-OG) on metabolism and function of isolated rat heart during hypoxia and reoxygenation were studied. Hearts were subjected to oxygenated perfusion with Krebs-Henseleit buffer supplied with 11 mM glucose (20 min) and anoxic perfusion with the buffer saturated with N2 (20 min), followed by reoxygenation (30 min). The substrate concentrations in the perfusate were 3.5 mM each. The additives had no effect on the energy metabolism and function of the oxygenated heart despite a two-fold rise in myocardial Asp and 2-OG. Substrate supplementation during anoxic perfusion resulted in reduced lactate dehydrogenase release and less depression of cardiac function. Prevention of Asp, glutamate, and 2-OG degradation in hypoxic myocardium was accompanied by relief of glycolytic flux and better preservation of ATP, phosphocreatine (PCr), and total creatine (Cr). Reoxygenation without the additives after supplemented anoxic perfusion failed to improve recovery of high-energy phosphates and cardiac function compared to control. However, during reoxygenation with the additives the treated hearts showed less cell membrane damage and enhanced recovery of contractile and pump function. These effects were associated with higher myocardial contents of ATP, PCr, and adenine nucleotides and a smaller Cr loss during reoxygenation. A more effective restoration of oxidative metabolism was related to promoted glucose oxidation due to replenishment of the malate-aspartate shuttle reactants. The results substantiate the use of substrates of cytosolic aspartate aminotransferase for myocardial protection against hypoxia/reoxygenation stress.

Seven horses developed clinical or subclinical hepatitis 48 to 87 days after administration of tetanus antitoxin. One horse had mildly high hepatic enzyme activity 120 days after inoculation with tetanus antitoxin. The first horse developed signs of depression, lethargy, and anorexia. During hospitalization, signs of hepatoencephalopathy were noticed, and laboratory data were consistent with hepatic disease. Another horse that was found dead had gross and histologic lesions compatible with serum hepatitis. Screening of serum gamma-glutamyltransferase (GGT) and aspartate transaminase activities were used to investigate the remaining horses in the herd. High GGT activities (71 to 206 IU/L) were detected in 5 additional herd members. These horses appeared clinically normal, apart from 2 reports of nasal photosensitization and an aborted fetus. In 3 horses, high serum GGT activity persisted over a 44-day testing period. All affected horses had been given tetanus antitoxin within 12 hours of parturition, and a common source of vaccine was identified for 7 horses. Findings in this group of horses indicate that clinical and subclinical serum hepatitis can develop after administration of tetanus antitoxin.

Monensin and lead were administered separately or concurrently at different toxic doses to broiler chicks. Administration of lead alone did not result in a significant depression of haematological parameters. Administration of higher levels of monensin caused a reduction in haematocrit and an increase in blood serum levels of alanine aminotransferase, aspartate aminotransferase and cholesterol. Concurrent administration of monensin and lead caused a severe depression of haematological profiles which indicated the existence of an interaction between the two substances. It was concluded that concurrent administration of monensin and lead potentiated the toxic effects of each other.

The purpose of this study was to determine the effects of experimental fasciolosis at various stages of development on the daily food intake of sheep. Five male Churra sheep, 4 months of age, were infected orally with 300 Fasciola hepatica metacercariae over a 30 day period. There was a significant increase in serum glutamate dehydrogenase (GLDH) activity from 40 days post-infection and in aspartate aminotransferase (AST) activity from 60 days post-infection. Both enzyme activities reached maximum levels in the serum of infected animals at 80 days and then progressively decreased. Serum gamma-glutamyltransferase (GGT) activity was significantly increased from 80 to 120 days post-infection. Glycaemia was significantly decreased from 60 days post-infection. The average daily food intake was shown to steadily decrease until approximately 100 days. The coincidence of decreased food intake with the period of significant increase, both in AST and GLDH activities, indicated that damage caused around the time of migration of immature flukes through the liver parenchyma may be involved in appetite depression.

The acute intraperitoneal toxicities of chlorambucil and chlorambucil-spermidine conjugate have been compared, in mice. Both compounds were neurotoxic and also caused a prolonged fall in bodyweight and a depletion of lymphocyte numbers associated with a fall in the total leukocyte count and loss of spleen and thymus weight. Alanine aminotransferase and aspartate aminotransferase activities and blood urea nitrogen concentration were increased at 24 h after conjugate administration, but had returned to normal at 72 h. Chlorambucil significantly decreased blood urea nitrogen concentration for 72 h, but did not affect transferase activity. Tissue concentrations of conjugate were measurable in liver and kidney for 12 days and lung for 5 days after dosing. The toxicity of both compounds was cumulative. In mol/kg, the chlorambucil-spermidine conjugate was 10-fold more toxic than chlorambucil, on the basis of their neurotoxicity, but only 2- to 3-fold more toxic on the basis of their effects on lymphocyte depression. The increased toxicity of the conjugate does not improve its therapeutic index relative to chlorambucil.

The electrocardiogram (ECG) was recorded and the serum levels of creatine kinase (CK), aspartate transaminase (ASAT) and prostatic acid phosphatase (PAP) was measured in 22 patients undergoing transurethral resection of the prostate (TURP) under spinal or epidural anaesthesia. The irrigating fluid consisted of 1.5% glycine and 1% ethanol, and absorption of the fluid was monitored by detection of alcohol in the expired breath. The results show that nine of the 11 patients (82%) who absorbed more than 1,000 ml of irrigating fluid had developed ECG changes 24 h after the operations. The most common alteration was depression of the T wave. This sign was only seen in one (9%) of the patients who absorbed none or very small amounts of irrigating fluid (P < 0.001). The serum activity of CK and ASAT increased in five patients who also developed ECG changes, and the highest values were recorded 24 h after TURP. The CK-MB isoenzyme was detected in 85% of the samples with elevated total CK, but the criteria for myocardial infarction were never fulfilled. In contrast, PAP increased in all patients and the highest level occurred at the end of TURP. The activity-time profiles suggest that CK and ASAT entered the circulation by a mechanism different from that of PAP. We conclude that absorption of glycine solution during TURP is frequently followed by nonspecific ECG signs of altered cardiac function and also that the serum activities of CK and ASAT increase in some of these patients.

Monensin and selenium (sodium selenite) at different toxic levels were administered orally to the broiler chickens for variable periods. A depression in haematological parameters and biochemical ones such as alanine and aspartate aminotransferase, serum total protein and cholesterol were recorded in acute and subacute toxicosis of these substances. The present experiments led to the conclusion that concurrent administration of selenium and monensin at toxic levels resulted in exasperated toxic response in broiler chickens which in turn had been produced by embellishment of toxicosis inducing properties of both examined substances.

An aqueous suspension of air-dried, hammer-milled leaf of Terminalia oblongata (yellow-wood) was administered to sheep by gavage, as a single dose of 5 to 20 g (dry weight)/kg body weight. Doses of 15 g/kg, or more, caused depression, inappetence, abdominal pain and reduced ruminal movements within 24 to 48 h and some sheep also showed dyspnoea, opisthotonus and champing of the jaws. Haematology and blood gas and acid-base measurements were unaffected. In sheep given a dose of 12.5 g/kg, or more, plasma osmolality, aspartate aminotransferase activity and potassium and bilirubin concentrations increased while plasma total protein markedly decreased and plasma sodium concentration and alkaline phosphatase activity remained normal. Most sheep were necropsied 48 h after dosing. The liver showed zonal hepatocellular necrosis, the pattern of which varied with the dose given. No renal lesions were observed, although one sheep given a very high dose became azotaemic and hyperkalaemic. Hydrothorax, hydropericardium and ascites developed in sheep given doses of 15 or 20 g/kg.

To characterize more fully sacahuiste (Nolina microcarpa Watson) toxicosis in sheep and to evaluate benefits of supplemental Zn, sheep were dosed intraruminally with sacahuiste blossoms. In Trial 1, eight fine-wool sheep (47 +/- 2 kg BW) were fed alfalfa hay at 1% of BW daily and dosed intraruminally with inflorescences amounting to 1% of BW daily, in three portions per day, for 10 d. Four sheep were dosed intraruminally with aqueous ZnSO4 (30 mg of Zn/kg BW) daily for 3 d before initial sacahuiste dosing and on alternate days thereafter, and four sheep were untreated with Zn. Toxicosis was evident within 24 h after initial sacahuiste dosage, involving inappetence, depression, hypokalemia, hypophosphatemia, hyperbilirubinemia, and elevated serum enzymes (alkaline phosphatase, creatine kinase, lactate dehydrogenase, aspartate aminotransferase, and gamma-glutamyl transpeptidase). One sheep (untreated with Zn) died on d 3. Aqueous ZnSO4 alleviated inappetence and suppressed elevation of serum urea N and creatinine but did not suppress other changes in serum clinical profiles. In Trial 2, sacahuiste inflorescences were ruminally dosed into 12 fine-wool wethers (29 +/- 2 kg BW) in amounts equalling 0, .25, .50, .75% of BW per day, and chopped alfalfa hay was provided at 1.75% of BW per day for 14 d. Sacahuiste inflorescenses dosed at .75% of BW elicited severe toxicosis within 24 h, and dosage at .50 or .25% of BW per day increased (P = .12) serum bilirubin. Ruminal fluid pH, mean particle retention time, and particulate passage rate were not affected (P > .10) by sacahuiste, but ruminal fluid passage rate increased 1.6-fold (P < .10) and ruminal fluid volume decreased by 60% (P < .10) in sheep given inflorescenses amounting to .50% of BW daily. Sacahuiste inflorescenses dosed intraruminally at .75% of BW per day elicited ruminal impaction with severe hepatotoxicosis, and dosages amounting to .50% or .25% of BW per day caused similar trends.
