Titanium dioxide nanoparticles (TiO NPs) are extensively incorporated in numerous industrial products. Adult male Albino rats received oral TiO NPs at a dose of 150 mg/kg body weight for 14 days exhibited both hepatic and renal toxicities manifested by disruption in serum hepatic and renal biomarkers, imbalance in oxidative-antioxidant system, up-regulation of mRNA expression of genes encode inflammation (IL-1β, TNF-α) and apoptosis (Caspase-3, BAX) with down-regulation of PCNA immune-staining density and histological modifications in hepatic and renal architecture. Carboxymethyl chitosan (5 mg/kg BW) significantly improved the harmful effects of nano-titanium particles highlighting its relevance in reducing TiO NPs - induced hepatic and renal dysfunction.
二氧化钛纳米颗粒（TiO NPs）被广泛应用于众多工业产品中。成年雄性白化大鼠以150毫克/千克体重的剂量口服TiO NPs，持续14天，结果显示出肝脏和肾脏毒性，表现为血清肝脏和肾脏生物标志物紊乱、氧化-抗氧化系统失衡、编码炎症（IL-1β、TNF-α）和凋亡（Caspase-3、BAX）的基因mRNA表达上调，同时增殖细胞核抗原免疫染色密度下调，以及肝脏和肾脏结构的组织学改变。羧甲基壳聚糖（5毫克/千克体重）显著改善了纳米钛颗粒的有害影响，突出了其在减轻TiO NPs诱导的肝脏和肾脏功能障碍方面的作用。
