Massive bleeding induced by disintegration of breast cancer tumors for 4 yrs (88 yrs-old lady) was treated by applying Mohs' paste (75g/45mL of Zinc complex). This huge site healed quickly and the healing effects were sustained for 48 days. Based on this clinical evidence, the hemostatic mechanism of Mohs' paste was evaluated using the hind limb ischemia model in mice. Unilateral hind limb ischemia was induced in 6 week-old male C57BL/6JJmsSlc mice by resecting the right femoral and saphenous arteries. Mice were painted once a day with Mohs' paste containing 0, 37.5, 50 and 62.5g/45mL of zinc after the surgery. Hind limb blood perfusion was measured by using a laser Doppler perfusion imaging system (moorLDI2-Ⅱλ : S/N 5489). To identify capillaries, the thigh muscles were harvested on Day 1 to make a tissue section and immunostained for CD31. One day after painting of Mohs' paste, blood flow suppression to the ischemic leg was significantly enhanced in a dose dependent manner. Furthermore, anti-CD31 immunostaining revealed that Mohs' paste decreased capillary density in the ischemic muscle. The results of both the clinical and animal studies suggest that Mohs' paste suppressed angiogenesis due to the acute effects of aggregated protein and the sustained effects of decreases of CD31.

Mohs paste is using for chemosurgery to treat local recurrence of breast cancer tumors and other tumors. However, physicochemical properties of Mohs paste such as hardness, viscosity, stickiness, and spreadability, change signifi cantly during storage after preparation. We investigated the mechanism of change in these physicochemical properties and reformulated Mohs paste. Mohs paste was very hard immediately after preparation and then gradually became soft and sticky during storage. We found that starch particles in the formulation caused the change in physicochemical properties. The initial hardening of the paste was caused by water adsorption and swelling of starch granules. The ensuing softening and tackifying were caused by gelatinization of the starch. The change in physicochemical properties could be restricted by reduction of free water in the formulation by adding a sugar alcohol. Sorbitol was the most effective material among additives because sorbitol can interact strongly with hydration water.
