摘要

背景:活性炭吸附是目前临床治疗急性有机磷农药中毒(AOPP)的主要方法。然而,这种方法的吸附时间和效率并不稳定。目的:本研究制备了一种包埋活性炭的水凝胶,并探讨了它对 AOPP 的缓解作用。方法:本研究使用海藻酸钠和聚乙烯醇(SA-PVA)制备了一种复合水凝胶。通过傅立叶变换红外光谱(FTIR)、热重分析(TGA)、X射线衍射(XRD)、扫描电子显微镜(SEM)、拉伸强度和膨胀率等多种分析对 SA-PVA 水凝胶的结构特性进行了表征。在此基础上,将活性炭(AC)嵌入 SA-PVA 水凝胶(SA-PVA-AC)中,用于处理 AOPP。结果:结构表征表明,SA-PVA 水凝胶具有优异的机械性能和生物相容性。体内研究表明,SA-PVA-AC 能明显减轻肝脏的炎症和氧化损伤,这体现在 IL-6、TNF-α、IL-1β、SOD 和 MDA 水平的降低上。此外,SA-PVA-AC 还能有效调节血清 AST 和 ALT 的活性,从而改善肝功能。结论:研究结果表明,嵌入 SA-PVA 水凝胶中的活性炭作为一种治疗剂,在治疗 AOPP 方面具有巨大潜力,并为控制农药引起的毒性提供了一种新方法。

Enhanced treatment of acute organophosphorus pesticide poisoning using activated charcoal-embedded sodium alginate-polyvinyl alcohol hydrogel
BACKGROUND:The adsorption of activated charcoal is currently a major clinical treatment for acute organophosphorus pesticide poisoning (AOPP). However, the adsorption duration and efficiency of this method is unstable. OBJECTIVE:In this study, a hydrogel embedding activated charcoal was prepared and its alleviating effects on AOPP were investigated. METHODS:A composite hydrogel using sodium alginate and polyvinyl alcohol (SA-PVA) hydrogel was prepared in this study. The structural properties of the SA-PVA hydrogel were characterized via multiple analysis including FTIR, TGA, XRD, SEM, tensile strength and expansion rate. Based on these, activated charcoal (AC) was embedded within the SA-PVA hydrogel (SA-PVA-AC) and it was used for the treatment of AOPP. RESULTS:Structural characterization indicated SA-PVA hydrogel possesses excellent mechanical properties and biocompatibility. The in vivo study demonstrated that SA-PVA-AC significantly alleviated the inflammation and oxidative damage in the liver, as evidenced by reduced levels of IL-6, TNF-α, and, IL-1β, SOD, and MDA. Furthermore, SA-PVA-AC treatment effectively re-regulated the activities of serum AST and ALT, exhibiting an improved effect on liver function. CONCLUSION:The findings suggest that activated charcoal embedded within SA-PVA hydrogel has significant potential as a therapeutic agent in treating AOPP, and offering a novel approach to managing pesticide-induced toxicity.
