摘要:Exposing the dorsal superficial skin of rats to partial-depth burn leads to bacterial and microbes Invasion. Topical treatment is required in most superficial burn cases Moist exposed burn ointment (MEBO) protects wounds from infection and enhances healing without any harmful effects of purified chemicals is caused. The topical using of HA gel in rat models with full and partial thickness surgical wounds shows enhancement in wound repair. In this study, we compared the healing efficacy of topical use of hyaluronic acid gel products with MEBO as standard management in rats that were exposed to a partial-thickness burn. The experiment included twenty-four (24) adult albino rats of male sex with weight (150-220 gm) of 3 months’ age divided into four groups. Partial-thickness burn wounds are applied on their shaved dorsal skin by a hot metal plate for 4 seconds. Group I: control group received topically normal saline as a vehicle placebo, group II: are treated topically with MEBO, Groups III & IV: are treated topically with hyaluronic acid gel (Afta Med and Gum Afta Clear) respectively twice daily for 14 days. The burn wound area was daily examined and measuring the diameter of the lesion area was until day 14 and photographs of the lesion area and wound repairs were taken at different time intervals (0,3,5,7, 10, and 14). % of wound contraction also detected. The rats were sacrificed on days 11 and 14, then elevates 5 mm of diameter full-thickness flap of healed and unhealed wound areas. Wound healing occurs faster when using HA gel products topically for treatment of the induced partialthickness burn when compared with using MEBO and control group which was supported with histological examination and statistical analysis.
摘要:Burn therapy (MEBT)/moist exposed burn ointment (MEBO) is an effective traditional Chinese medicine method to treat diabetic wound, but the mechanism is unclear. Autophagy has been proved to be closely related with wound healing, so MEBO/MEBT is hypothesized to promote diabetic wound healing by regulating autophagy. To explore the mechanism of moist exposed MEBT/MEBO promoting diabetic wound repair. Eighty male Wistar rats were randomly assigned to control (n = 20) and diabetic group induced by intraperitoneal injection of STZ (n = 60), which were further randomly assigned to MEBO, Kangfuxin and model groups (n = 20 each). All rats underwent full-thickness skin resection in the back. Wound healing was dynamically observed and wound tissues were collected at five time points for pathological examination, autophagosome and the expression of PI3K, Akt and mTOR. The healing time in the control group was the shortest, no statistically significant difference was found between the MEBO and the Kangfuxin group (p = 0.76). The morphology of autophagosomes ranged large to small, which was the most obvious in the MEBO group. The mRNA and protein expression of PI3K, Akt and mTOR in each group reached the peak on Day 5, the levels in the MEBO group were the highest (F = 18.43, 19.97, 15.36, p < 0.05). On Day 11, the expression levels in each group began to decline. In this study, we discussed the molecular mechanism of MEBT/MEBO promoting the repair of diabetic ulcer wounds through autophagy and PI3K-Akt-mTOR signalling pathway, which provides a new way for drug design in the future.
摘要:Background MEBO is an analgesic and antibacterial natural agent. Sesame oil extract plays a positive effect in wound healing that may be attributed to its ability to scavenge free radicals and antioxidant properties. Material and methods In this study, MEBO was topically applied to the site of a traumatic oral ulcer to examine its therapeutic effect on pain relief and wound healing. Patients were randomly assigned into two equal groups: group I (MEBO), group II (control), (n?=?15 patients each). Pain was recorded by using the Visual Analogue Scale (VAS), wound size was measured at days 2, 5, and 10. Cytological analysis was also performed using the superficial epithelial cell and keratinization indices. Results There was a statistically significant difference in VAS scores and wound size between MEBO group and control group (p?≤?0.001). Cytological results of MEBO group showed a highly significant improvement (p?≤?0.00001) in re-epithelization and keratinization indices over time. Conclusion Our results showed that the application of MEBO on traumatic ulcer sites has a significant improvement in wound healing and rapid enhancing effect on the re-epithelialization rate.
