Transjugular intrahepatic cavoportal shunt for Budd–Chiari syndrome

Budd–Chiari syndrome (BCS) is characterized by obstruction of the hepatic venous outflow tract. Therapeutic options for BCS are limited. We report a case of a 21-year-old woman with protein S and C deficiency with gross ascites. Treatment with transjugular intrahepatic portosystemic shunt (TIPS) was attempted, which revealed occluded hepatic veins, so transcaval TIPS was performed. No serious procedure-related complication occurred. After successful shunt creation, the patient's symptoms subsided and she was discharged and followed up for 6 months.

Separation of human basophils into two fractions with different density and histamine content

We designed experiments in this study to test the hypothesis suggested by recent purification data that blood basophils comprise two populations of different density, which circulate in numbers characteristic for each human subject. Basophils were separated into two density bands by single step centrifugation on a discontinuous Percoll gradient. Band 1 cells were at the interface between plasma and Percoll of density 1.070 gm/ml. Band 2 cells were at the Percoll 1.070 to 1.080 interface. When the number of band 1 basophils was expressed as a percentage of the total in bands 1 and 2, this relative amount generally remained in a narrow range for blood obtained from the same donor on 3 successive days but differed markedly in different individuals. In a series of leukapheresis experiments, we demonstrated that the percentage of band 1 basophils in postleukapheresis venous blood was strikingly similar to the preleukapheresis value. If basophils that repopulated the leukapheresis-depleted circulation came from the bone marrow, we can conclude that blood levels of basophils in bands 1 and 2 are under physiologic control and that the two types of basophils are released in amounts characteristic for each human subject. Additional evidence for two distinct blood basophil populations was provided by histamine measurements. The histamine content per basophil was consistently higher in cells from band 1 than from band 2, the mean difference between pairs of values for 30 subjects being 0.3 +/- 0.04 pg or about 27% of the band 1 basophil histamine content of 1.1 pg.
