X-ray exposure can result in acute or chronic damage to lung tissue, leading to pneumonitis and fibrosis. Given the potent antioxidant properties of sumac, this study investigates the impact of hydroalcoholic sumac extract on X-ray-induced pulmonary fibrosis in rats.
In this experimental study, 36 rats were randomly divided into six groups of six rats each. The treatment and sham groups received intraperitoneal administration of the extract daily for one week before exposure to X-ray radiation. On the seventh day, all rats except those in group 3 were exposed to 2 Gy of 6 MV X-rays using an electro-linear accelerator. Lung tissue was subsequently removed to assess the subacute effects of the extract. Data analysis involved independent sample t-tests and one-way ANOVA using SPSS 26.
A single dose of X-rays significantly increased oxidative stress and lung tissue damage in rats. However, rats receiving vitamin C and hydroalcoholic sumac extract at two different doses (100 and 400 mg/kg intraperitoneally) positively improved lung damage and decreased antioxidant parameters.
The findings demonstrate that hydroalcoholic sumac extract can mitigate oxidative stress and enhance lung repair following X-ray radiation exposure.
X射线照射可导致肺组织急性或慢性损伤,引发肺炎和纤维化。鉴于漆树具有强大的抗氧化特性,本研究调查了漆树水醇提取物对大鼠X射线诱导的肺纤维化的影响。
在本实验研究中,36只大鼠被随机分为6组,每组6只。治疗组和假手术组在接受X射线辐射前一周每天腹腔注射提取物。在第7天,除第3组大鼠外,所有大鼠均使用电子直线加速器接受2 Gy的6 MV X射线照射。随后取出肺组织以评估提取物的亚急性效应。数据分析采用SPSS 26进行独立样本t检验和单因素方差分析。
单次剂量的X射线显著增加了大鼠的氧化应激和肺组织损伤。然而,接受维生素C和两种不同剂量(腹腔注射100和400 mg/kg)漆树水醇提取物的大鼠,肺损伤得到了积极改善,抗氧化参数降低。
研究结果表明,漆树水醇提取物可减轻X射线辐射后的氧化应激并促进肺修复。
