Purpose: This study aims to examine effect of microcurrent electrostimulation on burn healing by electric intensity and of which the electric intensity on the acute burn being cured with microcurrent electrostimulation therapy. Methods: 28 Sprague Dawley Rats is classified into a control group of 8 rats, an experimental group I of 10 rats and an experimental group II of 10 rats. The control group is not cured, the experimental group I is exposed to 10 Hz, and $100{mu}A$ with microcurrent electrostimulation, and the experimental group II is exposed to 10 Hz, $300{mu}A$ for 15 minutes a day. The next day, 2th, 4th, and 6th day after rats is burned. Result: There are not significant differences of length change of the burn cure between the control group, the experimental group I, and the experimental group II by a period. However, systematically hair follicle cell on the 2th day and epidermal cell on the 6th day turn up in the experimental group I, and the experimental group II. Inquiry: Nancy(1994) did not obtain the desired result when the skin of a pig is exposed to 0.1 Hz, and $100{mu}A$ for wound healing. In the result of the study, when burn length is measured on the 2th, 4th, and 6th to see the length change of acute burn, there is not significant differences among 3 groups. Conclusion: Statistically, there is not significant differences of the length change between 3 groups. However, systematically the burn is cured faster in the experimental group I, and the experimental group II than in the contrast group.
