Chitosan is a natural polysaccharide that has attracted significant scientific interest during the last two decades and chitosan based nanodrug delivery systems seem to be a hopeful and viable strategy for improving disease treatment. This study aims to evaluate the potency of the polymer based nanochloroquine in application for attenuation of Plasmodium berghei infection in Swiss mice and effectiveness against the parasite induced oxidative stress and deoxyribo nucleic acid (DNA) damage in lymphocytes. Nanoparticle was prepared by ionotropic gelation between chitosan and sodium tripolyphosphate. The chloroquine was treated by the actual drug content of effective nanochloroquine and the nanodrug was charged with its effective dose for fifteen days, after successive infection development in Swiss mice. Gimsa staining of thin smear and flow cytometry analysis was pursued to reveal the parasitemia. Different oxidative markers, inflammatory markers, antioxidant enzymes level and also lymphocytic deoxyribo nucleic acid damage study were performed. The present study reveals the potency of the nanodrug which has been found as more prospective than only chloroquine treatment to combat the parasite infection, oxidative stress as well as inflammation and DNA damage. From the study, we conclude this nanodrug may be applicable as potent therapeutic agent than only chloroquine.
壳聚糖是一种天然多糖,在过去二十年中引起了科学界的极大兴趣,壳聚糖基纳米药物递送系统似乎是改善疾病治疗的一种有希望和可行的策略。本研究旨在评估基于聚合物的纳米氯喹在减轻伯氏疟原虫感染瑞士小鼠中的效力,以及对寄生虫诱导的氧化应激和淋巴细胞脱氧核糖核酸 (DNA) 损伤的作用。纳米颗粒是通过壳聚糖和三聚磷酸钠之间的离子凝胶化制备的。氯喹用有效纳米氯喹的实际药物含量处理,并在瑞士小鼠连续感染发展后 15 天内用有效剂量给纳米药物充电。吉姆萨染色薄涂片和流式细胞术分析用于揭示寄生虫血症。进行了不同的氧化标记物、炎症标记物、抗氧化酶水平以及淋巴细胞脱氧核糖核酸损伤研究。本研究揭示了纳米药物的效力,发现它比单独使用氯喹治疗更有前景,可对抗寄生虫感染、氧化应激以及炎症和 DNA 损伤。从研究中,我们得出结论,这种纳米药物可能比单独使用氯喹更适合作有效的治疗剂。
