Lipid peroxidation has been induced by means of an atherogenic diet causing hypercholesterolaemia, hypertriglyceridaemia, increased LDL and decreased HDL serum fractions in addition to the fatty degeneration, vacuolization of the liver cells and accumulation of malondialdehyde in the liver. Increased release of acid phosphatase and N-beta-glucuronidase was also observed pointing to cholesterol-induced lysosomal membrane damage. In response to pretreatment with, and simultaneous administration of, 6,6'-methylene bis (2,2-dimethyl-4-methane sulphonic acid sodium salt-1,2-dihydroquinoline) the signs and symptoms of fatty liver degeneration, the tissue, plasma and platelet malondialdehyde concentrations and the LDL serum fraction significantly decreased and HDL serum fraction increased. Lisosomal membrane stability was restored, resulting in physiological acid phosphatase and N-beta-glucuronidase activities. The pathological and clinical aspects of lipid peroxidation in several diseases of the digestive organs and the suggested therapeutic uses of non-toxic radical scavengers have been outlined.

Hypernatremic states, often the result of hypothalamic osmoreceptor dysfunction in humans, are sometimes accompanied by hyperlipemia. To investigate whether hypernatremia could cause hyperlipemia we induced hypernatremia in three groups of rats with their respective controls: Group A rats received hypertonic saline alone intragastrically; group B animals were pair-fed and tap water was substituted for hypertonic saline in the treated group; in group C the rats were again fed intragastrically with a liquid diet mixed with hypertonic saline. Rats receiving excess salt had mean serum Na+ concentrations exceeding 159 mmoles/l. While the serum triglyceride values were significantly higher in all hypernatremic rats, hepatic triglyceride content was greater only in group C rats (p less than .01). Serum free fatty acids and ketone bodies were also higher in group C rats (p less than .01) as compared to controls. These data suggest that hypernatremia by itself leads to hyperlipemia and a fatty liver.

The glutathione (GSH) S-transferases are believed to have dual functions as hepatic detoxifying enzymes and intrahepatic binding proteins. Little is known about their alterations in human liver diseases. Therefore, we have studied the relationship between the enzyme activity and rose bengal (RB) binding in hepatic cytosol and plasma indocyanine green (ICG) kinetics in patients with various liver diseases. The enzyme activity was measured in samples of hepatic cytosol obtained from 52 patients. In addition, the content of cationic and neutral transferases was estimated in 17 biopsy samples by densitometry of Coomassie blue stained sodium dodecyl sulphate polyacrylamide gel electrophoretograms. RB binding studies also were performed on cytosol samples. ICG kinetic parameters were determined using the two-compartment open model in 17 patients who were given the dye (0.5 mg kg-1) intravenously. Correlations between the enzyme activity and liver function tests, content of the enzyme, RB binding and ICG kinetic parameters were evaluated. The following results were obtained. (1) The enzyme activities were high in alcoholic liver disease, fatty liver and Gilbert's syndrome, and low in cirrhosis. (2) The enzyme activities were positively correlated with serum cholinesterase activity, serum albumin level and hepaplastin test, and negatively correlated with ICG retention rate at 15 min. (3) The enzyme activity, its content and RB binding affinity of the cytosol were positively correlated with each other. (4) The enzyme activity was positively correlated with hepatic ICG distribution volume. These results are consistent with the role of the GSH S-transferases as ligandins in intracellular storage of dyes.

'Magnesium ischaemia' is a term used to denote the functional impairment of the ATP-dependent sodium/potassium and calcium pumps in the cell membranes and within the cell itself. The production of ATP and the functioning of these pumps is magnesium-dependent and is critically sensitive to acidosis. Zinc and iron deficiencies may secondarily impair these pumps and thus contribute to 'magnesium ischaemia' (as does acidosis). This term is two-dimensional at its simplest; it refers to a functional magnesium deficiency, whether actual or induced. It is argued that chronic acidosis is the most common inducing factor. This simple hypothesis can begin to unify diverse pathophysiologies: some spontaneous abortions, aspects of Type II and gestational diabetes and the curious observation that heroin addicts become diabetic. It can also unify clinical thinking about pregnancy-induced hypertension, pre-eclampsia/eclampsia and acute fatty liver of pregnancy, as well as the coagulopathy of pregnancy. It makes important predictions about perinatal morbidity and suggests that early supplementation might prevent much pregnancy-induced disease.

Sera from 14 normal control subjects, 30 patients with alcoholic liver diseases (fatty liver, n = 8; hepatitis, n = 13; liver cirrhosis, n = 9), 7 controls with chronic hepatitis B, and 8 controls with chronic hepatitis C were masured for their concentrations of antibodies against HepG2 membrane protein by a binding assay utilizing 125I-labeled protein A. When the cut-off level was set as the mean value plus 2 SD of normal control subjects, the incidence of positivity was 75%, 69.2%, and 77.8% in patients with alcoholic fatty liver, alcoholic hepatitis, and alcoholic cirrhosis, respectively. Both the mean serum antibody values and the positive incidence were significantly higher in patients with alcoholic liver diseases than in either the normal controls or in the control patients with chronic hepatitis. Sodium dodecylsulfate polyacrylamide gel electrophoresis of 125I-labeled HepG2 membrane protein precipitated with IgG from patients with alcoholic liver diseases revealed an immunoreactive band at a molecular weight of 78,000 daltons (gp78). The antibody activity remained after immunoabsorption by human liver-specific lipoprotein (LSP) but decreased when HepG2 cells were pre-treated with trypsin or neuraminidase. Consequently, gp78 appears to be a glycoprotein distinct from LSP, and is specifically recognized by IgG from patients with alcoholic liver diseases. This assay may provide a new system to measure autoantibody to hepatocytes in alcoholic liver diseases.

The purpose of this work was to examine whether ursodeoxycholate (UDC), a hydrophilic bile salt, could reduce mitochondrial liver injury from chronic ethanol consumption in rats. Animals were pair-fed liquid diets containing 36% of calories as ethanol or isocaloric carbohydrates. They were randomly assigned into 4 groups of 7 rats each and received a specific treatment for 5 weeks: control diet, ethanol diet, control diet + UDC, and ethanol diet + UDC. Respiratory rates of isolated liver mitochondria were measured using a Clark oxygen electrode with sodium succinate as substrate. Mitochondria from rats chronically fed ethanol demonstrated an impaired ability to produce energy. At the fatty liver stage, the ADP-stimulated respiration (V3) was depressed by 33%, the respiratory control ratio (RC) by 25% and the P/O ratio by 15%. In ethanol-fed rats supplemented with UDC, both the rate and efficiency of ATP synthesis via the oxidative phosphorylation were improved: V3 was increased by 35%, P/O by 8%. All the respiratory parameters were similar in control group and control + UDC group. On the other hand, the number and size of mitochondria were assessed by electron microscopy and computer-assisted quantitative analysis. The number of mitochondria from ethanol-treated rats was decreased by 29%, and they were enlarged by 74%. Both parameters were normalized to control values by UDC treatment. These studies demonstrate that UDC has a protective effect against ethanol-induced mitochondrial injury by improving ATP synthesis and preserving liver mitochondrial morphology. These UDC positive effects may contribute to the observed decrease in fat accumulation and may delay the progression of alcoholic injury to more advanced stages.

Fluid therapy is practical and beneficial when properly administered to cattle. Mature cattle are more frequently alkalotic than acidotic, so nonalkalizing solutions are usually indicated. Exceptions include cattle with choke, carbohydrate engorgement, diabetes mellitus, and occasionally, renal disease, diarrhea, and fatty liver/ketosis. Many dehydrated cattle need supplemental potassium and calcium as well as sodium, chloride, and water. Intravenous administration is indicated in patients with obstructive gastrointestinal disease and those with severe dehydration. Oral or intraruminal administration is less expensive and, often, very effective.

In vitro studies indicated that a sodium bentonite (SB) from southern Argentina had a high ability to sorb aflatoxin B1 (AFB1) from aqueous solution. We evaluated this compound for its ability to reduce the effects of total aflatoxins (AF; 5 mg AFB1/kg) in the diet of growing broiler chickens from 30 to 52 d of age. The diets were amended with 0.3% Argentinean SB to determine the effect of this compound during aflatoxicosis. When compared with the controls, BW gains were significantly (P < 0.05) lower for broilers fed diets containing AF alone (1,865 vs. 1,552 g). No differences were found between the BW gains of broiler chickens fed diets without AF (1,785 g) and those of chickens fed AF + SB (1,809 g). These results suggest that effects of AF treatment were ameliorated when SB was used in the broiler chick diets. The AF significantly (P < 0.05) decreased feed efficiency. Liver, kidney, and pancreas relative weights increased in chickens fed the diet containing AF alone. Alterations in the levels of serum total protein, albumin (ALB), and globulins (GLOB) were observed for AF diets, and moderate protection was provided by the sorbent. The ALB:GLOB ratio decreased in both groups of birds fed with the AF-contaminated diet, and we observed a moderate increase in this ratio by 0.3% addition of SB. The histopathological findings in liver sections of broiler fed diets with AF + SB indicated a nonprotective effect of this adsorbent, because a moderate hepatic steatosis was observed.

We developed an intranasal powder form of glucagon to improve metabolic status and fatty liver in patients with pancreatectomy. Microcrystalline cellulose, which is commonly used in commercial preparations for allergic rhinitis was used as an absorption enhancer. We compared the intranasal powder form with some spray solutions of glucagon with regard to glucagon absorption, concentration of blood glucose, stability and nasal irritation. The absorption of glucagon from the spray solution including 1.5% sodium glycocholate or 1% sodium caprate was 1.3- and 2.6-fold higher than that from the powder form mixed with microcrystalline cellulose at a ratio of 1:69, respectively. The C(max) values of plasma glucose were 2.18, 3.39 and 1.56 mmol l(-1) in the spray solutions including sodium glycocholate and sodium caprate and in the powder form, respectively. However, glucagon in spray solutions was unstable, but that in the powder form was stable at 5 and 25 degrees C for at least 84 days. The spray solution caused strong irritation, but the powder form did not. These results suggested usefulness of the powder form of glucagon for treatment of pancreatectomized patients.

The effects of sodium borate (100 mg/kg body weight, p.o., 15 days) from a month before expected calving until a month after calving were evaluated in dairy cows susceptible to fatty liver. Cows received either sodium borate (n = 13) or no treatment (n = 10). All cows had mild fatty livers and increased plasma triglycerides and very low density lipoprotein (VLDL) concentrations at the beginning of the experiment. The control group of cows developed significant fatty liver after calving, and 2 of them had severe fatty liver associated with clinical and biochemical abnormalities. There were no clinicopathological signs related to sodium borate administration. Serum triglycerides and VLDL concentrations before calving decreased significantly at calving and after calving in controls, and they were within the normal range only after calving. There were significant alterations during the experiment in some hematological and chemical variables between groups, within period, but they were within the normal range. Unlike treated cows, serum triglycerides and VLDL concentrations correlated with liver fat content after calving in untreated cows. Our results document that sodium borate decreases the degree of fatty liver in dairy cows during early lactation.
