摘要：CONTEXT: Moist exposed burn ointment (MEBO), from China, has been said to revolutionize burn management. OBJECTIVE: Our study was conducted to compare MEBO with conventional management (C) with respect to the rate of wound healing, antibacterial and analgesic effect, and hospital costs. DESIGN: This is a prospective, randomized, controlled clinical trial conducted between 1 March 1997 and 24 October 1998. SETTING: The trial was conducted in a specialized burn facility located in a tertiary referral hospital in a developed and industrialized island-state in Southeast Asia. PATIENTS: We randomly assigned 115 consecutive patients between the ages of 12 and 80 who had partial-thickness thermal burns covering less than 40% of body surface area (BSA) to receive either MEBO or C. Fifty-seven patients were assigned to MEBO and 58 patients to C. The latter group received twice-daily dressing changes; MEBO patients received MEBO every 4 hours. MAIN OUTCOME MEASURES: Patients were hospitalized until 75% BSA had healed. BSA was determined by visual inspection and charted on Lund and Browder charts regularly. Wound healing rate, bacterial infection rate, pain score, and hospitalization costs were recorded. RESULTS: The median time to 75% healing was 17.0 and 20.0 days with MEBO and C, respectively (HR = 0.67, 95% CI = 0.41-1.11, P =.11), suggesting similar efficacy between the 2 modalities. Bacterial infection rates were similar between the 2 groups (HR = 1.10, 95% CI = 0.59-2.03, P =.76). MEBO imparted a greater analgesic effect in the first 5 days of therapy and reduced hospital costs by 8%. CONCLUSIONS: MEBO is as effective as conventional management but is not the panacea for all burn wounds. The use of MEBO eases the management of face and neck burns and facilitates early institution of occupational therapy in hand burns. It confers better pain relief such that fewer opiates are used during the first 5 days after burn injury.

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：Background: Despite the availability of many topical formulations for scar treatment, an objective evaluation of their effectiveness is lacking. Objective: To assess the physiological, structural, and mechanical parameters of scar healing by a scar ointment (MEBO-Scar). Methods: 45 patients from the Department of Obstetrics at Al Ain Hospital, UAE, with recently acquired Pfannenstiel scars were recruited into this prospective, open-label, controlled study. Scar ointment was applied to a lateral third of the scar; positive control (silicone gel based topical) to the other lateral third; the middle third was left untreated (negative control). The scars were evaluated at 4 time points up to 12 weeks using non-invasive devices and a scar questionnaire. Results: In comparison with silicone gel, there was a significant reduction in trans epithelial water loss at weeks 2, 4, 8, and 12 (p<0.001) and scar area at weeks 4, 8 and 12 (p<0.001) with scar ointment. The skin elasticity at week 4 was significantly increased by scar ointment (p=0.007). By week 12, gross colour mismatch of the scar was described by 9% patients with scar ointment (24% with silicone gel, 42% with no treatment; p<0.001). There was a significant improvement in scar texture with scar ointment by week 12 (p<0.001). Conclusion: Scar ointment has beneficial effects on objective and subjective patient-reported parameters of Pfannenstiel scars.

摘要：In this study, we sought to test the medical efficacy of a Chinese medical herb product, moist exposed burn ointment (MEBO), on wound healing rate and infection control in burn injury. Standardized deep burn wounds were created on the back skin of rats by applying a hot brass bar for 12 to 18 seconds. MEBO was applied four times per day and compared with petroleum jelly, silver sulfadiazine, and dry exposure therapy. Under such a controlled setting, although MEBO had a better wound healing rate than the dry exposure treatment, it did not show the medical advantage statistically, as has been claimed, over the other two treatments (P > .05), either in terms of wound healing rate or bacterial control. We conclude that the MEBO is not suitable for deep burn wound treatment, particularly when infection is a concern.
