[0050] method

[0051] cell culture

[0052] The human Met-5a cell line was purchased from the American Type Culture Collection (ATCC, Rockville, MD). All the cells were cultured in the M199 medium supplemented with L-glutamine (0.1 gram / liter), penicillin (100 U / ml), streptomycin (100 μg / ml), 10% fetal bovine serum (FBS), and at 37°C with 5% CO 2 Breed in humid air in an incubator. Unless otherwise stated, standard chemicals were purchased from Sigma-Aldrich (St. Louis, MO, USA). Falcon TM Tissue culture plastic (Becton Dickinson Company, Franklin Lakes, NJ, USA) was used for all cell culture procedures.

Abstract

The present invention relates to a peritoneal dialysis fluid comprising a compound inhibiting glycogen synthase kinase (GSK)-3 activity, in particular (GSK)-3beta activity, for use in the prevention of infectious and non-infectious peritoneal complications such as peritonitis, peritoneal membrane injury, damage and failure, barrier dysfunction and mesothelial cell detachment.

Description

technical field [0001] The present invention relates to a peritoneal dialysis solution (hereinafter also referred to as "PDF"). Background technique [0002] Compared with hemodialysis, peritoneal dialysis (PD) is a safe, cost-effective renal replacement therapy that provides better quality of life. However, peritoneal dialysis treatment often results in a progressive decline in the ultrafiltration function of the membrane, often associated with peritoneal tissue changes and loss of peritoneal integrity (1). [0003] Currently, more than two-thirds of patients suffer from PD-related infectious or non-infectious complications (such as peritonitis, degeneration of peritoneal function, or technical deficits) during the first two years of their treatment. [0004] Different kinds of fluids are available for PD. The difference between these fluids is the type of osmotic agent, its concentration and the type of buffer and pH value in the PD fluid. [0005] In clinical practice,...
