Arm II: Patients receive standard local therapy only for 12 weeks. Patients randomized to
arm II may cross over to receive arginine butyrate if no or less than 25% healing is
observed after 12 weeks.

Patients whose ulcers have closed by at least 15% per course may receive 2 additional 8-week
courses of arginine butyrate therapy and are followed for 2 months after healing is
