Effect of Methanolic Extract of ‎Sea Cucumber (Holothuria ‎leucospilota Brandt, 1835) on ‎Wound Healing of Rat

Prolongation of wound healing time can be led to chronic infections. Therefor, to achieve infection preventive methods to accelerate of wound improvement process is one of essential needs of Human. In this study, the effects of methanolic extract of Holothuria leucospilota was investigated on restoration of created wound in rat skin.  Methanolic extracts of collected sea cucumber from depth of 10 to 15 meters was prepared by rotary. The amount of  0.5 and 1 gr of obtained extraction were added to base ointment. In continuing, 40 rats (average mean of 185±5 gr) were divided into 4 groups which included control, sham (base cream), 0.5% ointment and 1% ointment. Wound (diameter of 6±1 mm) was created on rats’ skin by punch biopsy.  Each group were treated (1ml) with prepared concentrations ointment during 13 days. On days of 0, 4, 7, 10 and 13, the wound improvement process was investigated and the diameter of the wounds was measured. According to results, accelerate the wound recovery process was more obvious in treated groups with 0.5% and 1% ointment compared to control and sham groups. Also, there was significant different between treated group with 1%, sham and control during days of 7, 10, 13 (P<0.05).
