Male and female virgin rats and breeder rats with naturally-occurring diabetes, hypertension and arteriosclerosis, were made severely diabetic with a single, subcutaneous injection of alloxan (10 mg/100 g b.w.), after an 18 h fast. During five months of unrelenting diabetes, some animals became obese while others became emaciated. Only the emaciated animals survived but they were blind, their adrenal glands were hemorrhagic, hypertrophied and thrombosed, thymi involuted, kidneys swollen, hearts reduced in size while testes and ovaries were atrophic. Serum CPK, SGOT and SGPT were elevated concomitant with extensive cardiovascular damage, hepatic steatosis and generalized catabolism. Circulating triglycerides and free fatty acids were markedly elevated with total cholesterol only slightly increased. BUN and serum calcium levels were also greatly elevated. Sub-normal Cmpd. B levels indicated impaired adrenal steroidogenesis. Virgin rats developed arteriosclerosis and male and female breeder rats showed exacerbation of their pre-existing aortic sclerosis as well as P.A.N. lesions in their small-sized arteries. It is believed that severe diabetes causes exacerbation of the endogenous hormonal milieu resulting from abnormal hypothalamic-pituitary-adrenal function induced by repeated breeding, which conditions the connective tissue components of the arterial wall of rats toward accelerated degenerative changes.

Commercial laying hens with Fatty Liver Syndrome had greatly elevated levels of serum calcium and cholesterol. Most of the hens with the elevated serum calcium and cholesterol were out of production, but some were still in production. Hens with elevated calcium and cholesterol levels had extremely large combs and excessive deposits of fat in the abdomen.

Serum 25-hydroxyvitamin D3 levels were determined in chronic hepatic diseases by a radioreceptor assay and correlated with serum albumin, calcium and anorganic phosphate, 25-hydroxyvitamin D3 serum levels were significantly lower inall chronic hepatic diseses compared to normals. The low levels are correlated with the degree of parenchymal damage, not with the etiology of hepatic disease. In alcoholic liver disease thus 25=hydroxyvitamin D3 levels are significantly lower when cirrhosis is present than in mere fatty liver. Anorganic phosphate and calcium were close to the lower range of normal and significantly lower than in the control group studied.

Twenty-one samples of water were collected from commercial egg production farms in Georgial with or without a history of fatty liver syndrome. These samples plus a sample of water from the University of Georgia Poultry Farm were analyzed for various mineral elements by atomic absorption, direct reading emission spectroscopy and by neutron activation. Water samples from farms with a history of fatty liver syndrome had signficantly more calcium, magnesium, strontium, sodium, iron and barium than water samples from farms reporting no significant problem with fatty liver syndrome. Levels of manganese, boron, copper zinic and aluminum were not significantly different. Although the results do not prove that water quality is the cause of the disease, they do demonstrate an association of hardness of water with fatty liver syndrome that should be further investigated.

In Japan, acute encephalopathy with hepatic steatosis resembling Reye's syndrome has been reported to occur after treatment with the pantothenic acid antagonist, calcium hopantenate. We studied the causal relationship and the pathogenesis in dogs. The agent was administered to seven dogs at increasing doses over a period of 8 weeks. Anorexia, vomiting, and diarrhea were common clinical findings. In four dogs, coma suddenly developed after the appearance of gastrointestinal signs. Three animals died during periods when they were not under direct observation. The effects of the agent appear to be related to dose. Laboratory findings representing significant changes at the time of coma included hypoglycemia, leukocytosis, hyperammonemia, hyperlactatemia, and elevated levels of serum transaminases. Microvesicular hepatic steatosis and mitochondrial abnormalities were consistent pathological findings. The hepatic mitochondria were enlarged and characterized by an increased number of cristae and the presence of crystalloid inclusions. In a second group of four dogs, pantothenic acid was given in addition to and in the same amount as calcium hopantenate at increasing doses over a period of 8 weeks. All four dogs survived the 8 weeks and only one developed mild anorexia. No significant biochemical changes were found and neither hepatic steatosis nor mitochondrial abnormalities were observed. The addition of pantothenic acid prevented the development of the disorder in the four animals. These results show that calcium hopantenate produces acute encephalopathy with hepatic steatosis in dogs, by inducing a deficiency of pantothenic acid. The hepatic mitochondrial changes of this reaction differ from those of Reye's syndrome.

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. Most 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.

Thioridazine (TDZ) administration to rats (50 mg/kg i.p.) 6 or 10 h after CCl4 treatment (1 ml/kg in olive oil i.p.) partially prevented necrogenic effects of this compound at 24 h but not at 72 h. TDZ did not have inhibitory effects on CCl4 activation, covalent binding (CB) of reactive metabolites to cellular constituents or CCl4-induced lipid peroxidation (LP). Moreover, TDZ had enhancing effects on both LP and CB. TDZ was able to increase protein and phospholipid synthesis and slightly but significantly enhanced protein but not phospholipid degradation in livers from control rats. TDZ administration decreased calcium liver content in CCl4-poisoned animals but did not change the intensity of CCl4-induced fatty liver. TDZ lowered body temperature in CCl4-treated animals during the 24 h observation period. These results and previous studies from our laboratory suggest calcium and calmodulin (CaM) participation in the CCl4 necrogenic effects on the liver but not in the hepatotoxin-induced fatty liver. TDZ-lowering effects on body temperature might also be a determinant in the delaying effects of this drug on the onset of CCl4-induced necrosis. Present experiments did allow discrimination between these two or other possible mechanisms for TDZ modulation effects.

31P NMR was used to study the erythrocytes of three patients who exhibited a familial multisystem disease characterized by fatty liver, diabetes and nonspherocytic hemolytic anemia of unknown etiology. 31P NMR measurements disclosed an abnormally high level of intracellular inorganic phosphate (Pi) and an abnormally low level of ATP in the erythrocytes 6 h after blood withdrawal from proband (I-1). This finding suggested that ATP was markedly decreased in the red cells of this proband, as compared with those of normal subjects. Time-dependent changes of 31P NMR spectra of the erythrocytes from the two daughters (II-1, II-2) of the proband demonstrated clearly an enhanced decomposition of ATP with a concomitant increment of Pi. Several ATP-consuming enzymes in erythrocytes, such as those in the Embden-Meyerhof system, pentose phosphate pathway enzymes, Na+, K(+)-ATPase and Ca2+, Mg2(+)-ATPase, were within normal limits of activity, but Mg2(+)-ATPase was drastically above the normal limit. The Mg2(+)-ATPase activity was 3 times higher in the red cell membranes of these patients than in those from normal subjects.

1. Male Mongolian gerbils (Meriones unguiculatus) liver activates CCl4 to free radicals that bind covalently to cellular components (CB) and stimulate a lipid peroxidation (LP) process to a larger extent than the rat liver. 2. CCl4 administration results in a less intense necrogenic effect in gerbils than in rats and does not cause fatty liver. 3. CCl4 causes less intense effects on liver ultrastructure or calcium metabolism but more marked depression of glucose 6 phosphatase activity (G6P-ase) in gerbils than in rats. 4. Results suggest that a better ability of gerbil liver to keep calcium homeostasis than rat liver might be the cause of their relative resistance to necrosis. Higher intensity of CB and LP in gerbils than in rats might explain more intense effects on G6P-ase.

In agreement with the hypothesis that changes in calcium homeostasis might be significant in late stages of chemically-induced liver cell injury, a calcium chelating agent, Calcion, was able to partially prevent CCl4-induced liver necrosis observed at 24 h, when treatment was given as late as 6 or 10 h after the hepatotoxin. Calcion had minor or no effects on covalent binding of reactive metabolites to cellular components, or on lipid peroxidation or on CCl4 levels reaching the liver. Calcion treatment of CCl4-poisoned animals decreased CCl4-induced calcium increases in liver and increased glutathione levels decreased by hepatotoxin at 24 h. Calcion treatment was not able to prevent CCl4-induced fatty liver. Calcion protective effects were body temperature dependent but they were cancelled when Calcion-treated poisoned animals were kept normothermic. Results suggest that Calcion protective effects might be linked to calcium chelation or alternatively that they might derive from decreases in body temperature.
