Abstract

|
|
The oriental ore minerals, which mainly consisted of talc, actinolite, sericite, and halloysite were developed, and then used to examine the healing effect on the skin wound in rats. Full-thickness square wounds were formed on the backs of rats after the hairs on the dorsal surface were shaved. The ore minerals were applied to examine the healing effect from day 0 to 15 after wounding. Notable wound healings in terms of congestion around the wound, wound contraction and epithelialization were found in ore mineral-treated groups. Moreover, microscopic results revealed the formation of epithelial layer, hair follicles and progressive angiogenesis in ore mineral-treated groups, while complete epithelial layer could not be found in the control. These results suggest that ore minerals from Korean indigenous ores may have wound healing effect on the skin injury in rats.
