title: The effect of antisera to insulin, 2-deoxyglucose-induced hyperglycemia, and starvation on wound healing in normal mice.
abstract: Wound healing was examined in normal C57BL/6 male mice treated with antiserum to insulin or 2-deoxyglucose (2-DG) and in mice starved for 33 h. Hyperglycemia was induced after antiserum or 2-DG treatment; the blood glucose was lowered in the starved mice when compared with controls. Small dermal wounds were made in the ears of the mice 1 h after the initial injection of antisera or 2-DG. The starved group were wounded after 25 h of fasting. All animals were biopsied 8 h later. The wounds were examined by light microscopy and wound components (capillaries, fibroblasts, PMNs, collagen, and edema) were quantitated by lineal point analysis. Mice treated with antisera to insulin and mice starved for 33 h had an impaired healing response; the mice treated with 2-DG had a response similar to controls. These results suggest that hyperglycemia, per se, or the production of any toxic metabolites from high blood glucose levels could not alone induce the poor healing response. The depressed response in the antiserum-treated and starved mice may be due to the decreased availability of insulin to the wound tissues. These data support the hypotheses that insulin is a necessary component for an adequate wound healing response. In addition to a role in glucose transport and metabolism, insulin may also promote cellular growth.
