The purpose of this experiment was to know the healing effects of saualene on the burned mouses. The experimental groups were divided into seven groups: the control group, the burned groups, and 50 treated groups after burned. All groups except the control group burned with second degree on a dorsoanterior part. All groups that treated with 50 adapted three drops of pure squalene at 10 seconds interval; one time a day. The histological and ultrastructural changes during 10 days after burned were observed by light and electron microscope. Under the light microscope, all parts of epidermal layer of the burned groups were wounded deeper than the 50 treated groups. At 6 and 10 days groups with 50 treated, especially 10 days, the basal layer was greatly differentiated, and the prickle cells in the spinous layer were greatly increased in number. Under the electron microscope, the cell divisions of basal layer in all groups that treated with 50 were more activated and rapidly regenerated than the all burned groups. Especially, some fantastic results obtained from the 10 days group with SQ treated; much thicker spinous layer than the control group, many prickle cells, fine intercellular bridges, and healthy basal layer contained melanocytes. These results suggest that squalene may active the epidermis growth factor (EGF), acts as scavenger, and provide sources of energy in the membrane system. The results of this experiment consider that squalene has specific effects for burn healing and regeneration.
