Materials and Methods This was a double blind, randomised, placebo-controlled crossover trial in eight healthy young men. The study was performed in random order on two separate days, with a four-week washout period between days. Subjects received an infusion of Alanine-glutamine ( Dipeptiven) at a rate of 0.025 g / (kg BW * h) for 10 hrs or saline. After two hours of infusion subjects received an intravenous bolus of E. coli endotoxin (0.3 ng/kg). Blood samples were collected hourly for the following eight hours. HSP-70 protein content in isolated Blood Mononuclear Cells (BMNCs) was measured by western blotting.
