Soybean protein-derived peptide nutriment increases negative nitrogen balance in burn injury-induced inflammatory stress response in aged rats through the modulation of white blood cells and immune factors

Background: As an important nutrient, soybean protein-derived peptides (SPP) affect the immune function of animals. Objective: This study describes the effects of nutrient supplementation with SPP on the negative nitrogen bal- ance in the burn injury-induced inflammatory response of aged rats. Design: Soybean protein isolate (SPI) was hydrolyzed to obtain SPP. A negative nitrogen-balance aged rat model and a major full-thickness 30% total body surface area (TBSA) burn-injury rat model were...
