According to the various independent studies conducted, it is well evident fact that radiation induces oxidative stress in the living system. It is also proved that this oxidative stress will lead to the various behavioural changes such as anxiety and memory impairment. Kinetin is one of the important plant cytokine with anti-aging properties. However, very few studies were conducted to check its potential in ameliorating the behavioural changes induced by the ionizing radiation.
This study was aimed to check the potential of kinetin in ameliorating the radiation induced behavioural changes in albino mice.
In this study, survival analysis was performed using three different dose of kinetin intervention along with, one radiation control group and one normal control group (n=50). Based on the cumulative survival rate, single effective dose of kinetin was selected and used to evaluate the behavioural changes induced by radiation. The open field apparatus was used to evaluate the anxiety level (n=18, six in each group). Eight armed radial maze was used to evaluate the memory and learning ability in mice model.
Survival study results suggest 100 mg/kg body weight of kinetin showed highest cumulative survival rate. Therefore, this dose was selected as an effective drug dose for further study. Analysis also showed 6 Gy whole body electron beam radiation had significantly increased anxiety level, increased duration to complete the task as well as mistakes done during the task. Further, kinetin intervention had significantly ameliorated the same.
A 100 mg/kg body weight of kinetin intervention helps in reducing the anxiety and improves the learning ability in mice exposed to electron beam radiation.
根据各项独立研究,辐射在生物系统中诱发氧化应激这一事实已十分明显。此外,也已证实这种氧化应激会导致各种行为变化,如焦虑和记忆障碍。激动素是一种具有抗衰老特性的重要植物细胞分裂素。然而,很少有研究检测其在改善电离辐射诱发的行为变化方面的潜力。
本研究旨在检测激动素改善白化小鼠辐射诱发行为变化的潜力。
在本研究中,使用三种不同剂量的激动素干预进行生存分析,同时设置一个辐射对照组和一个正常对照组(n = 50)。根据累积生存率,选择激动素的单一有效剂量并用于评估辐射诱发的行为变化。使用旷场装置评估焦虑水平(n = 18,每组6只)。使用八臂辐射迷宫评估小鼠模型的记忆和学习能力。
生存研究结果表明,100 mg/kg体重的激动素显示出最高的累积生存率。因此,该剂量被选为进一步研究的有效药物剂量。分析还表明,6 Gy全身电子束辐射显著增加了焦虑水平、完成任务的持续时间以及任务期间出现的错误。此外,激动素干预显著改善了这些情况。
100 mg/kg体重的激动素干预有助于减轻暴露于电子束辐射的小鼠的焦虑并提高其学习能力。
