Chronic superior mesenteric venous thrombosis revealed by diabetic ketonuria and bacteremia.

We report a patient with superior mesenteric venous thrombosis presenting as diabetic ketonuria and bacteremia. The patient was a 65-year-old man with a history of diabetes mellitus, and was admitted to our hospital due to high fever. Tests revealed diabetic ketonuria and Bacteroides fragilis bacteremia.

Evaluation of proliferation and functional differentiation of LLC-PK1 cells on porous polymer membranes for the development of a bioartificial renal tubule device.

To develop a bioartificial renal tubule system using renal tubular cells and porous polymer membrane hollow fibers, long-term maintenance of a confluent monolayer and the functionally differentiated condition of cells is essential. We examined the proliferation and functional differentiation of LLC-PK1 (Lewis-lung cancer porcine kidney 1) cells on two types of membranes: polysulfone and cellulose acetate. Cell proliferation was significantly higher on the polysulfone membrane than on the cellulose acetate membrane, and was enhanced by coating the membranes with various extracellular matrices.
