Abstract:

BACKGROUND: Increasing evidence suggests that Sanguis draxonis is of great significance for treating pressure sores, burns and ulcers.
OBJECTIVE: To observe the influences of Sanguis draxonis on vascular endothelial growth factor, epidermal growth factor, substance P and hydroxyproline in rats undergoing tissue-engineered skin transplantation and to verify its promotion of wound repair.
METHODS: The tissue-engineered skin transplantation model of rats were established. Rats in treatment groups were given external application, single oral use of 0.1 g/(kg•d) Sanguis draxonis and combined use, respectively. No treatment was given in control group. After continuous treatment for 7 days, the expression levels of vascular endothelial growth factor, epidermal growth factor, substance P and hydroxyproline in skin tissue were determined.
RESULTS AND CONCLUSION: Compared with the control group, the levels of vascular endothelial growth factor, epidermal growth factor, and hydroxyproline were significantly increased (P < 0.05 or P < 0.01), while substance P had no change in the treatment groups (P > 0.05). These results demonstrate that Sanguis draxonis can promote tissue-engineered skin to repair skin wound by upregulating the expression levels of vascular endothelial growth factor, epidermal growth factor, and hydroxyproline.
