Unidirectional air flow isolators were used to house laying hens at 13 degrees C, 18--30 degrees C and 29 degrees C. Their diet was formulated to provide 2655 k cal metabolisable energy/kg and 142 g crude protein/kg. Groups were killed for examination at the age of 35 and 45 weeks. Sub-clinical FLHS occurred in all isolators but in the case of the younger hens appeared to be more prevalent at 29 degrees C than at 13 degrees C. Both the triglyceride and the glycogen content of the liver were higher at 29 degrees C despite a reduction in food intake. The free fatty acid level in the plasma was lower, probably as a consequence of reduced lipolysis. Liver haemorrhage was associated with an increase in plasma aspartate transaminase activity. It was concluded that an interaction between environmental temperature and the energy balance is not the only factor involved in the aetiology of FLHS and maybe of secondary importance, and that there is a pathogenic relationship between hepatic steatosis and haemorrhage.

An integrative survey is given of three disease processes, in which recent progress of a fundamental nature has been made, primarily affecting the liver, either coincident with or caused by the gravid state. The three conditions considered include (1) recurrent cholestasis of pregnancy (RCP), (2) viral hepatitis coincident with pregnancy, and (3) acute fatty liver of pregnancy (AFLP). In addition to an assessment of our present knowledge with respect to RCP and AFLP, new genetic hypotheses are proposed. In the latter, the proposal of an ornithine transcarbamylase deficiency, similar to that seen in Reye's syndrome, has potential therapeutic implications that are explored. In light of the currently available information on the interaction between maternal viral hepatitis and the variant forms of vertical maternal-fetal transmission, tentative recommendations regarding management of the newborn are suggested.

The catabolism of chylomicrons was investigated in genetically obese rats and their nonobese littermates, and was compared with catabolism in older Sprague-Dawley rats with body weights similar to the obese rats and their younger controls. Labeled thoracic-duct lymph was collected from donor rats and the catabolism of the labeled chylomicrons was studied after a single intravenous injection or during steady intravenous infusion in unanesthetized, nonfasting, recipient rats. In the genetically obese rats clearances from the plasma of chylomicron triacylglycerol and cholesteryl ester were less than in their nonobese littermates. Fractional clearance rates were reduced for both triacylglycerol and cholesteryl ester but triacylglycerol turnover rate (mg min(-1)) was greater than controls. Chylomicron triacylglycerol clearance was more efficient than cholesteryl ester clearance so that radioactivity remaining in the plasma was relatively depleted in triacylglycerol. The large-bodied old Sprague-Dawley rats showed no reduction in clearance of chylomicron radioactivity in comparison with younger controls. These results suggest that hyperlipidemia in genetically obese rats may be due in part to an accumulation of chylomicron remnants in the plasma. Flotation characteristics of plasma lipoproteins in the obese rats were consistent with this interpretation. However, separate experiments showed that genetically obese, fasting rats also accumulated more triacylglycerol in the plasma after injection of Triton WR 1339. The enlarged plasma triacylglycerol pool appears to derive from a mixture of hepatic and intestinal triacylglycerol-rich lipoproteins which, together, overload their common removal mechanism. Addition of cholesterol to the diets of the obese rats exacerbated their hyperlipemia and hepatic steatosis whereas their nonobese littermates and the large-bodied Sprague-Dawley rats were unaffected.

Rats were fed for 24 days a liquid diet with ethanol as 36% of calories to produce hyperlipemia and hepatic steatosis. The catabolism of chylomicrons doubly-labeled in the triacylglycerol and cholesteryl ester moieties was studied in conscious rats after ingestion of their usual liquid diets with or without ethanol. A constant intravenous infusion of chylomicrons revealed a defect in chylomicron catabolism after chronic treatment with ethanol. The plasma clearance of chylomicron cholesteryl ester was impaired to a greater extent than clearance of chylomicron triacylglycerol. These findings are consistent with defective catabolism of chylomicron remnants, and suggest that the accumulation of chylomicron remnants in the plasma contributes to the development of increased post-prandial hyperlipemia and chronic hyperlipemia in association with excessive ethanol consumption.

The most serious adverse effect of standard intestinal bypass for obesity is the high incidence of hepatic dysfunction and death from hepatic failure. We therefore examined the long-term effects of a modified form of jejunoileal bypass (in which a greater continuous length of ileum is retained), on liver function in 120 patients. Substantial weight loss (119-0+/-SD 23-3 kg to 82-3+/-18-8 kg) occurred during the first nine months after surgery, accompanied by a significant rise in serum concentrations of bilirubin, alanine transferase, and alkaline phosphatase, and a significant reduction in albumin concentrations. Biochemical changes were unrelated to weight loss or halothane anaesthesia. After weight stabilisation liver function reverted to normal, and four years after bypass sulphobromophthalein retention and hepatic histology did not differ from those in obese controls. There were two postoperative deaths. Three other patients died during the period of rapid weight loss with severe hepatic steatosis. While transient mild impairment of liver function is common after modified jejunoileal bypass, clinically significant hepatic dysfunction is a rare and unexplained early complication.

To evaluate the role of insulin in familial hypertriglyceridemia, 34 relatives of the pedigrees of 3 index cases of endogenous hypertriglyceridemia and hepatic steatosis as well as 9 spouses were examined for plasma lipids and responses of blood glucose and plasma insulin during oral glucose tolerance tests. The combined disorders of hypertriglyceridemia and hyperinsulinemia plus glucose intolerance--insulin resistance--were most commonly found among the relatives, which were often accompanied by an impaired liver function. Some relatives showed hyperinsulinemia without hypertriglyceridemia. Obesity was frequent, but its incidence was similar to the controls. Thus, the observed form of familial hypertriglyceridemia was apparently coupled with insulin resistance; and hyperinsulinemia, or insulin resistance by itself, might be a basic genetical trait in this form of lipid disorder.

Supplementing chick diets causing fatty liver and kidney syndrome (FLKS) with a wide range of minerals or with antibiotics did not affect mortality significantly but supplements of isolated soy protein or a mixture of crystalline amino acids were both equally effective in reducing mortality. Biotin supplementation of the parent flock diet subsequent mortality among the progeny by 30 per cent. Data on the age-distribution of the syndrome and the general conclusions from a whole series of experiments are presented.

Single Comb White Leghorn layers maintained in cages were fed a corn-soy diet with a simplified vitamin premix for a 12-week experimental period to determine the effect on liver lipid accumulation. Lipid content was only 29.6% of the liver dry matter and, therefore, was in the normal range and less than that seen in hens with fatty liver syndrome. Adding niacin (44 mg./kg.) or biotin (110 mug./kg.) either alone or in combination failed to significantly alter liver weight or liver lipid content. Liver lipid content of hens fed another diet with a more complex vitamin premix also was not significantly different from that of hens fed the diet with the simplified vitamin premix. None of the diets significantly affected egg production, egg weight, feed consumption or body weight changes observed over the 12-week period.

Determination of histocompatibility antigens in 63 patients with alcoholic liver disease showed that HLA-B8 was more prevalent in patients with cirrhosis than in controls, but among those with fatty liver and minimal fibrosis the prevalence of this antigen was normal. Another noticeable difference was the absence of HLAA28 in the cirrhotic group. In the total series of 219 patients the prevalence of antinuclear and smooth muscle antibodies was raised; they were especially prevalent in patients with cirrhosis. Raised serum IgA and IgG concentrations were also common (found in 50% and 37% respectively) and were again significantly associated with cirrhosis. In contrast, serum IgM levels, which were raised in 46% of cases, were not significantly related to the presence of cirrhosis but correlated significantly with the degree of portacaval shunting. These results support recent evidence suggesting that immune responses may be implicated in alcohol-induced liver damage, particularly in its progression to cirrhosis.

The influence of sex, age, and liver function on the androgenmetabolizing capacity of the liver was investigated. To that end, testosterone was administered orally to healthy men, women and prepubertal boys as well as to men with liver dysfunction. While normal men (n = 17) and men with fatty liver (n = 9) showed no rise in circulating plasma testosterone levels and only a slight increase in androstenedione, a steep increase in both steroids was observed in men with liver cirrhosis (n = 7). Unlike adult men, boys (n = 7) and women (n = 6) also showed elevated testosterone levels after oral administration of this steroid. It is concluded that the hepatic capacity to metabolize testosterone is influenced by sex, stage of development, and liver function. It seems possible that peripheral concentration of testosterone after its oral administration can serve as a clinical test for liver function.
