Background and Purpose. This study aimed to evaluate the wound healing activities of Aftamed and chlorine dioxide gels in streptozotocin-induced diabetic rats. Experimental Approach. Forty-eight Sprague Dawley rats were chosen for this study, divided into 4 groups. Diabetes was induced. Two-centimeter-diameter full-thickness skin excision wounds were created. Animals were topically treated twice daily. Groups 1, the diabetic control group, were treated with 0.2 mL of sterile distilled water. Group 2 served as a reference standard were treated with 0.2 mL of Intrasite gel. Groups 3 and 4 were treated with 0.2 mL of Aftamed and 0.2 mL of chlorine dioxide gels respectively. Granulation tissue was excised on the 10th day and processed for histological and biochemical analysis. The glutathione peroxidase ,superoxide dismutase activities and the malondialdehyde (MDA) levels were determined. Results. Aftamed-treated wounds exhibited significant increases in hydroxyproline, cellular proliferation, the number of blood vessels, and the level of collagen synthesis. Aftamed induced an increase in the free radical-scavenging enzyme activity and significantly reduced the lipid peroxidation levels in the wounds as measured by the reduction in the MDA level. Conclusions. This study showed that Aftamed gel is able to significantly accelerate the process of wound healing in diabetic rats.
背景与目的。本研究旨在评估 Aftamed 和二氧化氯凝胶在链脲佐菌素诱导的糖尿病大鼠中的伤口愈合活性。
实验方法。选择 48 只 Sprague Dawley 大鼠进行本研究,分为 4 组。诱导糖尿病。创建 2 厘米直径的全层皮肤切除伤口。动物每日接受两次局部治疗。第 1 组,糖尿病对照组,用 0.2ml 无菌蒸馏水治疗。第 2 组作为参考标准,用 0.2ml Intrasite 凝胶治疗。第 3 组和第 4 组分别用 0.2ml Aftamed 和 0.2ml 二氧化氯凝胶治疗。第 10 天切除肉芽组织,进行组织学和生化分析。测定谷胱甘肽过氧化物酶、超氧化物歧化酶活性和丙二醛(MDA)水平。
结果。Aftamed 治疗的伤口羟脯氨酸、细胞增殖、血管数量和胶原合成水平显著增加。Aftamed 诱导的自由基清除酶活性增加,并通过降低 MDA 水平显著降低了伤口中的脂质过氧化水平。
结论。本研究表明,Aftamed 凝胶能够显著加速糖尿病大鼠的伤口愈合过程。
