Natural products, including their purified materials, play a remarkable role in drug development. The Euphorbiaceae family, mainly , is used in some traditional medicine, and has evidence that its latex comprises immunomodulatory properties and cytokine production. This study aimed to measure the production of chemokines (IL-1α, IL-1β, IL-12, and RANTES), T1 cytokines (IFN-γ, TNF-α, GM-CSF, and IL-2) and T2 cytokines (IL-4, IL-6, IL-10, and IL-13) in rats after treatments with ethanol latex extract of . Vaccine treated and untreated rats were divided into seven groups to assess antimicrobial activities of the extracted components. After completion of the treatment schedule, blood was withdrawn and sera were collected. The results showed that the main component of the extract was a euphol compound. The extract showed antimicrobial activity and had the ability to modulate innate and adaptive immunity. Animals treated with extract for only 7 days before vaccination showed higher levels of antibody production. The extract showed antibacterial and antifungal activities. The extract could stimulate both adaptive and innate immunity. Pre-treatment with the extract increased immune responses in vaccinated animals, indicating the usefulness of the extract before immunization.
天然产物,包括其纯化物质,在药物开发中发挥着显著作用。大戟科植物,主要是……,被用于一些传统医学,并且有证据表明其乳胶具有免疫调节特性和细胞因子产生能力。本研究旨在测量用……乙醇乳胶提取物处理后的大鼠体内趋化因子(IL-1α、IL-1β、IL-12和RANTES)、T1细胞因子(IFN-γ、TNF-α、GM-CSF和IL-2)以及T2细胞因子(IL-4、IL-6、IL-10和IL-13)的产生情况。将接种疫苗和未接种疫苗的大鼠分为七组,以评估提取成分的抗菌活性。在完成治疗方案后,采集血液并收集血清。结果表明,提取物的主要成分是大戟醇化合物。该提取物具有抗菌活性,并具有调节先天性和适应性免疫的能力。在接种疫苗前仅用提取物处理7天的动物表现出更高水平的抗体产生。该提取物具有抗菌和抗真菌活性。该提取物可刺激适应性免疫和先天性免疫。用提取物预处理可增强接种疫苗动物的免疫反应,表明提取物在免疫前具有实用性。
