Abstract

Wound healing in diabetic patients is slower than in healthy individuals. Erythropoietin (EPO) has non-hemopoietic targets in the skin, and systemically administered EPO promotes wound healing in experimental animals. This study investigated the effect of topical EPO treatment on defective wound repair in the skin of diabetic rats. Full-thickness excisional skin wounds were made in 38 rats, of which 30 had diabetes. The wounds were then treated topically with a cream that contained either vehicle, 600 IU ml(-1) EPO (low dose), or 3,000 IU ml(-1) (high dose) EPO. We assessed the rate of wound closure during the 12-day treatment period, and microvascular density (MVD), vascular endothelial growth factor (VEGF), and hydroxyproline (HP) contents, and the extent of apoptosis in wound tissues at the end of the 12-day treatment period. Topical EPO treatment significantly reduced the time to final wound closure. This increased rate of closure of the two EPO-treated wounds in diabetic rats was associated with increased MVD, VEGF, and HP contents, and a reduced extent of apoptosis. In light of our finding that topical EPO treatment promotes skin wound repair in diabetic rats, we propose that topical EPO treatment is a therapeutically beneficial method of treating chronic diabetic wounds.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
