Sepsis is a clinical condition causing tissue damage as a result of infection and an exaggerated immune response. Sepsis causes 11 million deaths annually, a third of which are associated with acute lung injury (ALI). Rapid and effective treatment is crucial to improve survival rates. (pomegranate) is rich in polyphenols and demonstrates strong antioxidant activity, while amifostine acts as a free radical scavenger. This study aimed to investigate the antioxidant and anti-inflammatory effects of peel extract (PGPE) and amifostine in sepsis-related ALI. Experimental groups included Control, CLP (cecal ligation and puncture-induced sepsis), Amf (200 mg/kg amifostine, intraperitoneally), and PGPE250, and PGPE500 (250 and 500 mg/kg PGPE via oral gavage, respectively). Thiobarbituric acid reactive substances (TBARS), total thiol (TT), tumor necrosis factor-alpha (TNF-α) levels, and metalloproteinases 2 and 9 (MMP-2 and MMP-9) were assessed in the lung tissue. Biochemical analysis demonstrated that TBARS and TNF-α levels significantly decreased in both the PGPE and amifostine treatment groups compared to the CLP group, while TT levels showed notable improvement. Histopathological evaluation revealed reduced MMP-2 and MMP-9 immunopositivity in the PGPE250 and PGPE500 groups. These findings highlight the lung-protective properties of PGPE, underscoring its potential as a therapeutic agent for sepsis-induced acute lung injury.
脓毒症是一种临床病症,由感染和过度免疫反应导致组织损伤。脓毒症每年造成1100万人死亡,其中三分之一与急性肺损伤(ALI)有关。快速有效的治疗对于提高生存率至关重要。石榴富含多酚并具有强大的抗氧化活性,而氨磷汀是一种自由基清除剂。本研究旨在探讨石榴皮提取物(PGPE)和氨磷汀在脓毒症相关急性肺损伤中的抗氧化和抗炎作用。实验组包括对照组、CLP(盲肠结扎和穿刺诱导的脓毒症组)、Amf(200mg/kg氨磷汀,腹腔注射)、PGPE250组和PGPE500组(分别通过灌胃给予250mg/kg和500mg/kg的PGPE)。评估肺组织中的硫代巴比妥酸反应性物质(TBARS)、总硫醇(TT)、肿瘤坏死因子-α(TNF-α)水平以及金属蛋白酶2和9(MMP-2和MMP-9)。生化分析表明,与CLP组相比,PGPE组和氨磷汀治疗组的TBARS和TNF-α水平均显著降低,而TT水平有明显改善。组织病理学评估显示,PGPE250组和PGPE500组中MMP-2和MMP-9的免疫阳性率降低。这些发现突出了PGPE的肺保护特性,强调了其作为脓毒症诱导的急性肺损伤治疗药物的潜力。
