Inhibition of procollagen C-proteinase reduces scar hypertrophy in a rabbit model of cutaneous scarring.

Hypertrophic scarring, which results from excessive collagen deposition at sites of dermal wound repair, can be functionally and cosmetically debilitating to the surgical patient. Pharmacological regulation of collagen synthesis and deposition is a direct approach to the control of scar tissue formation. One of the key steps in collagen stabilization is the cleavage of the C-terminal propeptide from the precursor molecule to form collagen fibrils, a reaction catalyzed by procollagen C-proteinase (PCP).

Dermal changes in the lower leg skin of patients with venous hypertension.

Patients with chronic venous disease may develop characteristic changes in the skin of the lower limb known as lipodermatosclerosis (LDS). The affected skin becomes indurated and pigmented and often ulcerates. The degree of induration associated with LDS correlates directly with ulcer formation and leads to a subsequent delayed rate of healing.
