The paper describes a case of jaundice in a three-year-old bassett hound. The illness was accompanied by hyperbilirubinaemia and raised serum levels of alkaline phosphatase and glutamic pyruvic transaminase, indicating the presence of both biliary obstruction and hepatocellular damage. Examination of liver biopsies on two occasions showed intrahepatic cholestasis and mild inflammatory change. The dog was treated with corticosteroid. The jaundice regressed after three months, hepatic functions returned to normal and the dog recovered. The cause of the jaundice was not determined.

The diagnosis and treatment of a case of lead poisoning in a cynomolgus monkey (Macaca fascicularis) are described. The clinical signs were jaundice and amaurosis. Clinicopathological findings suggested cholestasis. A tentative diagnosis of lead poisoning was made when basophilic stippling of erythrocytes was observed in a peripheral blood smear. The diagnosis was confirmed by finding a lead concentration of 2280 micrograms/litre in a venous blood sample. Cage bars painted with red lead appeared to be the source of the poison. The lead was chelated by the intramuscular administration of 2,3 dimercapto-1-propanol (BAL) and calcium disodium edetate for seven days, followed by oral D-penicillamine for five weeks. The encephalopathy was treated with dexamethasone sodium phosphate. Recovery from the blindness was noted after 10 days and marked improvement of the general well being of the animal was observed after one month.

Liver samples from four groups of calves were analysed chemically and histologically for copper and iron levels. Milk replacer-fed 'yellow' calves were compared with milk replacer-fed 'white' calves, concentrate and silage-fed 'pink' calves and concentrate and silage-fed young 'red' fattening bulls. In the milk replacer-fed calves high copper and low iron levels were measured in the liver, whereas in the concentrate and silage fed pink calves and fattening bulls lower copper and higher iron levels were found. The yellow calves appeared to be icteric and had chronic hepatitis. Their hepatic histopathology was characterised by fibrosis, cirrhosis, fatty change, increased amounts of stainable copper, necrobiosis and prominent cholestasis; some animals had intranuclear inclusion bodies in the hepatocytes. They had similar or lower hepatic copper levels than the white calves and varying iron levels, indicating that copper toxicity was not the primary cause of the hepatic damage.

Four cows with cholestasis, whose general condition was moderately to severely disturbed, were examined. Two of them had signs of colic, and one had severe pruritus. All of them had jaundice and three had dermatitis solaris. Bilirubinuria occurred in three of the cows and they all had increased concentrations of serum bilirubin and serum bile acids and increased activities of hepatic enzymes. An ultrasonographic examination of the liver and gallbladder revealed that in one cow only the extrahepatic bile ducts were dilated, in another only the intrahepatic bile ducts were dilated and in the other two both the intrahepatic and extrahepatic bile ducts were dilated. In three of the cows the gallbladder was severely dilated and the wall was thickened. Ultrasonographically, the bile appeared either anechoic or echogenic. Surgical or post mortem examinations revealed that the cholestasis in one cow was attributable to obstruction of the common hepatic duct in the area of the hepatic hilus, in two it was caused by obstruction of the common bile duct near the duodenal papilla, and in the fourth cow, the common bile duct was compressed by adhesions, resulting from peritonitis, which involved the liver, gallbladder and abdominal wall.

The clearance profiles of intravenously injected tracer doses of radioactively labelled cholic acid were investigated in healthy dogs, dogs with a congenital portosystemic shunt and dogs with cholestasis. The rate constants and residual plasma activity were significantly different in the healthy and diseased dogs, but it was not possible to differentiate between the dogs with portosystemic shunting and cholestasis because the results were determined not only by factors involved in plasma bile acid clearance but also by the enterohepatic circulation.

A nonparasitic lamprey in Japan, Lethenteron reissneri, stops feeding prior to the commencement of metamorphosis. Resumption of feeding cannot take place due to major alterations in the digestive system, including loss of the gall bladder (GB) and biliary tree in the liver. This degeneration of bile ducts is considered to depend on programmed cell death or apoptosis, but molecular evidence of apoptosis remains lacking. Using terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining and immunohistochemistry with an antibody against active caspase-3, we showed that epithelial cells of the cystic duct (CD) and GB became TUNEL-positive by the early metamorphosing stage. Immunohistochemical staining of active caspase-3, a key mediator in the apoptotic cascade, showed that the apoptotic signal was initiated in the region around the CD in the late larval phase. In later stages, active caspase-3-positive epithelial cells were also observed in the large intrahepatic bile duct (IHBD) and peripheral small IHBDs. At the early metamorphosing stage, bile canaliculi between hepatocytes were dilated and displayed features resembling canaliculi in cholestasis. Onset of apoptosis around the CD, which is the pathway for the storage of bile juice, and progression of apoptosis towards the large IHBD, which is the pathway for the secretion of bile juice, may lead to temporary intrahepatic cholestasis. The present study represents the first precise spatial and temporal analysis of apoptosis in epithelial cells of the biliary tract system during metamorphosis of any lamprey species.
