Temporary bile diversion in cats with experimental extrahepatic bile duct obstruction.

The use of a cholecystostomy catheter for temporary bile diversion was investigated in four cats with experimentally induced extrahepatic bile duct obstruction. Eighteen days after ligation of the common bile duct, a 6.5 F accordion catheter was placed in the gallbladder with a 22 g Hawkins needle-guide system through a paracostal incision. Biochemical parameters and fasting serum bile acids were monitored for 16 days. There were significant decreases in mean total bilirubin, aspartate aminotransferase, and fasting serum bile acids within 72 hours of bile diversion, and in mean alanine aminotransferase within 96 hours. Attitude and appetite improved, and the catheter was tolerated well. Positive bile cultures developed in three cats. Histologic changes in the gallbladder included mucosal ulcerations, a mixed inflammatory cellular infiltration, and fibrosis of the submucosa.

The role of vaccinia virus in the evolution of some human hemopathies.

Six cases of severe hemopathy, detected following smallpox revaccination are described. Their onset was favoured by vaccinia virus-induced suppression of cell-mediated and humoral immunity. In two leukemia patients humoral immunity was present, but insufficient to assure protection of the diseased organisms, the outcome being fatal. The pancytopenia syndrome recorded in 4 patients with anergy caused by autoimmune mechanisms had different outcomes: favourable in 2 cases and fatal in the other 2 patients, who died within 4 years.
