Unaltered Fungal Burden and Lethality in Human CEACAM1-Transgenic Mice During Dissemination and Systemic Infection.

Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1, CD66a) is a receptor for It is crucial for the immune response of intestinal epithelial cells to this opportunistic pathogen. Moreover, CEACAM1 is of importance for the mucosal colonization by different bacterial pathogens. We therefore studied the influence of the human CEACAM1 receptor in human CEACAM1-transgenic mice on the colonization and infection utilizing a colonization/dissemination and a systemic infection mouse model.

Leukocyte/endothelium activation and interactions during femoral percutaneous transluminal angioplasty.

Recent data suggest that leukocyte-endothelium activation/interactions are important for restenosis after percutaneous transluminal angioplasty (PTA). Ten patients with superficial femoral artery occlusive disease (stage Fontaine IIb) were examined after a percutaneous transluminal angioplasty (PTA) versus a preceding aortoangiography (AAG). Blood samples from corresponding femoral arteries and veins were obtained before, immediately after, and 4 hours after each procedure.

Short-term hemodynamic effects of immunoadsorption in dilated cardiomyopathy.

Background: Previous studies have shown that the sera of many patients with dilated cardiomyopathy (DCM) are positive for several antibodies directed against cardiac antigens. Anti-beta1-adrenergic receptor antibodies occur in 70% to 90% of DCM patients. These antibodies are extractable by immunoadsorption (IA).

[In vitro modification of plasma viscosity and erythrocyte aggregation by four plasma substitutes].

We tested the haemorheological effects of the addition of 3.5% oxypolygelatine, 10% dextran 40, 6% dextran 75 or 5% albumin, respectively, to fresh donor blood of 25 healthy young persons. We examined the aggregation and the viscosity of substituent plasma mixtures in such various, but constant volume relations as may be present during intravenous infusion.
