This research article elucidates the pivotal role of radiopharmacy in the contemporary landscape, underscoring its potential therapeutic efficacy in addressing symptoms associated with aged-related neurocognitive processes. Clinical trials, characterized by the judicious application of modest radiation doses, exemplified by low-dose radon, have yielded affirmative outcomes in the amelioration of aged, related symptoms.
The study was conducted on an animal model. The effect of low doses of radon on cognitive processes is being studied by inhalation of randomized mineral water. Changes in the clinical picture were studied using behavioral tests, namely the Barnes maze tests. At the cellular level, radon-contained water inhalation causes different changes: in the fraction of synaptic membranes (determined by Na, K-ATPase activity), aged, related changes by telomerase activity and oxidative stress level changes.
Our studies show that age-related changes in brain tissue are less noticeable after radon inhalation, namely, the concentration of amyloid plaques decreases in a group of aged rats after radon therapy. A significant improvement in cognitive function was observed after radon inhalation in aged rats.
The results show that exposure to radon-containing mineral water leads to improved spatial perception, potentially improving age-related cognitive functions not only at the level of neurocognitive tests, but also changes at the level of cellular functioning.
本研究文章阐明了放射药学在当代背景下的关键作用,强调了其在解决与年龄相关的神经认知过程相关症状方面的潜在治疗效果。临床试验以适度的辐射剂量(如低剂量氡)为特征,证明了其在改善老年相关症状方面的积极效果。
该研究在动物模型上进行。通过吸入随机矿泉水来研究低剂量氡对认知过程的影响。使用行为测试(即 Barnes 迷宫测试)研究临床症状的变化。在细胞水平上,含氡水的吸入会引起不同的变化:突触膜的分数(通过 Na、K-ATPase 活性确定)、端粒酶活性和氧化应激水平变化引起的与年龄相关的变化。
我们的研究表明,氡吸入后脑组织的年龄相关变化不那么明显,即在氡治疗后一组老年大鼠中淀粉样斑块的浓度降低。在老年大鼠中,氡吸入后观察到认知功能显著改善。
结果表明,暴露于含氡矿泉水会导致空间感知改善,可能不仅在神经认知测试水平,而且在细胞功能水平上改善与年龄相关的认知功能。
