The widespread use of glyphosate as a herbicide in agriculture can lead to the presence of its residues and metabolites in food for human consumption and thus pose a threat to human health. It has been found that glyphosate reduces energy metabolism in the brain, its amount increases in white muscle fibers. At the same time, the effect of chronic use of glyphosate on the dynamic properties of skeletal muscles remains practically unexplored. The selected biomechanical parameters (the integrated power of muscle contraction, the time of reaching the muscle contraction force its maximum value and the reduction of the force response by 50% and 25% of the initial values during stimulation) of muscle soleus contraction in rats, as well as blood biochemical parameters (the levels of creatinine, creatine phosphokinase, lactate, lactate dehydrogenase, thiobarbituric acid reactive substances, hydrogen peroxide, reduced glutathione and catalase) were analyzed after chronic glyphosate intoxication (oral administration at a dose of 10 μg/kg of animal weight) for 30 days. Water-soluble C fullerene, as a poweful antioxidant, was used as a therapeutic nanoagent throughout the entire period of intoxication with the above herbicide (oral administration at doses of 0.5 or 1 mg/kg). The data obtained show that the introduction of C fullerene at a dose of 0.5 mg/kg reduces the degree of pathological changes by 40-45%. Increasing the dose of C fullerene to 1 mg/kg increases the therapeutic effect by 55-65%, normalizing the studied biomechanical and biochemical parameters. Thus, C fullerenes can be effective nanotherapeutics in the treatment of glyphosate-based herbicide poisoning.
草甘膦作为一种除草剂在农业中的广泛使用会导致其残留和代谢物出现在人类食用的食物中,从而对人类健康构成威胁。已经发现草甘膦会降低大脑中的能量代谢,其在白肌纤维中的含量增加。同时,慢性使用草甘膦对骨骼肌动态特性的影响在实践中尚未得到充分研究。在慢性草甘膦中毒(以 10μg/kg 动物体重的剂量口服) 30 天后,分析了大鼠比目鱼肌收缩的选定生物力学参数(肌肉收缩的综合功率、达到肌肉收缩力最大值的时间以及刺激期间肌肉收缩力减少 50%和 25%初始值的时间)和血液生化参数(肌酐、肌酸磷酸激酶、乳酸、乳酸脱氢酶、硫代巴比妥酸反应物质、过氧化氢、还原型谷胱甘肽和过氧化氢酶的水平)。水溶性 C60 富勒烯作为一种强大的抗氧化剂,在整个草甘膦中毒期间(以 0.5 或 1mg/kg 的剂量口服)用作治疗纳米试剂。所得数据表明,以 0.5mg/kg 的剂量引入 C60 富勒烯可使病理变化程度降低 40-45%。将 C60 富勒烯的剂量增加到 1mg/kg 可使治疗效果提高 55-65%,使研究中的生物力学和生化参数正常化。因此,C60 富勒烯可以成为治疗草甘膦类除草剂中毒的有效纳米药物。
