Myringosclerosis is an irreversible pathological healing mechanism of the tympanic membrane which can result in the formation of sclerotic plaques. Antioxidant treatment is a recognised prevention therapy and coenzyme Q10 (CoQ10), lycopene, and grape seed extract (GSE), were used in this manner.
Forty-four Wistar rats were used in this experiment, and, following myringotomies, the animals were randomly divided into four groups. CoQ10, lycopene or GSE was administered orally to the respective groups, starting from the day of surgery. Otomicroscopy examination was performed on the 14th day. All tympanic membrane lesions were evaluated and compared otomicroscopically and histopathologically.
The otomicroscopy and histopathological findings, compared against a control (saline) group, showed the CoQ10, lycopene, and GSE groups had statistically significant differences of degree of sclerosis (P<0.001).
CoQ10, lycopene, and GSE were compared against a saline group and their antioxidative and anti-inflammatory effects were similar. The formation of myringosclerotic plagues after experimental myringotomy in rats significantly decreased and diminished after systemic administration of the three different antioxidant supplements.
鼓膜硬化是鼓膜不可逆的病理愈合机制,可导致硬化斑形成。抗氧化治疗是一种公认的预防疗法,辅酶Q10(CoQ10)、番茄红素和葡萄籽提取物(GSE)已被用于此。
本实验使用44只Wistar大鼠,在鼓膜切开术后,将动物随机分为四组。从手术当天开始,分别对相应组口服CoQ10、番茄红素或GSE。在第14天进行耳显微镜检查。对所有鼓膜病变进行耳显微镜和组织病理学评估及比较。
与对照组(生理盐水)相比,耳显微镜和组织病理学结果显示,CoQ10、番茄红素和GSE组在硬化程度上有统计学显著差异(P<0.001)。
将CoQ10、番茄红素和GSE与生理盐水组进行比较,它们的抗氧化和抗炎作用相似。在大鼠实验性鼓膜切开术后,全身给予三种不同的抗氧化补充剂后,鼓膜硬化斑的形成显著减少并减轻。
