Solen dactylus inhabits on sandy–muddy beaches which is distributed throughout the coast of the northern Persian Gulf. The aim of this study is investigate effect of different habitats on proximate composition of S. dactylus. For this purpose, 20 oyster were collected from Bandar Abbas and Sirik city. 16 different types of amino acids were identified. The highest levels of essential and non-essential amino acids were lysine and glutamine in Sirik, arginine and glutamine in Bandar Abbas. Also, 30 different types of fatty acids were identified. The most and least saturated fatty acids abundant identified were palmitic acid and henicosilicic acid in Sirik samples, palmitic acid and pentadecylic acid in Bandar Abbas samples. Regarding monounsaturated fatty acids, the most and least fatty acids abundant were cis-oleic acid and gadolinic acid in samples collected from Sirik, cis-oleic acid and cis-10-pentadecylic acid in Bandar Abbas samples. Docosahexaenoic and eicosapentaenoic acid were identified as the highest and lowest polyunsaturated fatty acids in the samples collected in Sirik, docosahexaenoic acid and tert-linoleic acid were identified as the highest and lowest polyunsaturated fatty acids in the samples collected in Bandar Abbas. The results showed that the moisture, protein and ash content in samples collected from soil (medium sand classified) in the Sirik region were significantly higher than those in the samples collected from soil (fine sand classified) in Bandar Abbas (P<0.5). Based on the results obtained, S. dactylus is a good source of amino acids and fatty acids.

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).
