Whey Peptides Promote Wound Healing

BEIJING—Post-caesarean treatment with whey peptides (WP) promoted significant wound healing in the skin incision, and had a significant wound healing potential in the uterus, according to a study published in the British Journal of Nutrition (Aug. 9, 2010). A total of48 rats were randomly divided into two groups. After a caesarean section, 24 rats were intragastrically administered WP, while others were administered a control vehicle. On days seven, 14 and 21 after delivery, the serum total protein/albumin concentration, skin tensile strength, uterine bursting pressure, skin/uterine hydroxyproline (Hyp) concentration and histological characteristics of the scar were measured in eight rats in each group. In the WP group, the albumin concentration, skin tensile strength, uterine bursting pressure and Hyp concentration in the skin increased significantly on days 21, seven, 14 and 21, respectively. Low neutrophil count and smaller scar width in the skin incision were found in the WP group on day seven.
