BACKGROUNDSevere burn damage and its consequences are life threatening which can complicate patients’ health. Medicinal and traditional plants are considered as safe, natural and inexpensive source of treatment for wide variety of diseases. This study assessed beneficial effect of Pistacia atlantica oil on rats burn wound healing and its potential effects on malondialdehyde (MDA), vasculoendothelial growth factor (VEGF), hydroxyprolin and antioxidant status in wound area.METHODSThirty male rats weighing 200±10 g were randomly divided into three groups (n=10) as follows. Group 1 underwent just burn injury, Group 2 underwent burn injury and received 150 mg/kg/day P. atlantica oil topically, and Group 3 underwent burn injury and received 150 mg/kg/day sulfadiazine cream topically. At the end of the study (day 14), wounded areas were measured and then skin in the burn damage were dissected and anti-oxidative parameter, MDA, VEGF and hydroxyprolin were evaluated. RESULTS P. Atlantica oil significantly increased antioxidant defense, VEGF, hydroxyprolin and reduced MDA levels. It could remarkably reduce wound size compared to burn control group. P. Atlantica oil showed more beneficial effects than sulfadiazine.CONCLUSION P. atlantica resin oil could be considered as a new therapeutic agent for treatment of injuries.
diabetes mellitus is a chronic metabolic disorder which is followed by many complications. one of these problems following diabetes is diabetic ulcers and 2.5% of diabetic patients develop foot ulcer annually. Natural resources are useful stock for finding traditional treatment. Studies which examined Pistacia atlantica properties showed that it has some beneficial effects including: antimicrobial, antifungal, antioxidant and wound healing. Yet, Pistacia atlantica resin oil effects on diabetic wound have not been examined. Therefore, we evaluate Pistacia atlantica resin oil antioxidant and wound healing activity. Sprague-Dawley male rats were entered to the study and randomly grouped (n = 10) as follows: group 1-control group-burnt rats which received neither STZ nor Pistacia atlantica resin oil; group 2-diabetic burnt rats; group 3-diabetic burnt rats which received 250 µl/day Pistacia atlantica resin oil topically as an ointment for two weeks. at the end of the study antioxidant status, Vascular Endothelial Growth Factor (VEGF) and hydroxyproline contents were examined in the wound area. Our results showed that Pistacia atlantica resin oil has remarkable antioxidant activity in STZ-induced diabetic rats. Also, it promoted VEGF and hydroxyproline contents in the wound area which showed that it increases angiogenesis and collagen turnover in the diabetic wound. We concluded that Pistacia atlantica resin oil can be considered as a new therapeutic agent in diabetic wound healing, and also it is safe, available and cheap treatment of other wounds and skin injuries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
