■今天,高压(HV)线路为在附近甚至在这些线路下生活或工作的人类创造了有害的环境。雄性恒河猴用于研究HV塔产生的场的影响。这项研究从小脑的认知角度考察了恒河猴大脑的功能和影响水平,生物,结构视角。
■使用了两只猴子,一个作为对照,第二个作为测试。受试猴子经受3kV/m的模拟高压电场,一天4小时,一个月。使用为此目的设计和制造的装置进行行为测试。通过逆转录聚合酶链反应方法进行促肾上腺皮质激素(ACTH)的浓度分析和糖皮质激素受体基因(GR)的表达检查。用磁共振成像(MRI)检查小脑解剖结构的变化。在研究期间之前和之后进行所有测试,并与对照猴进行比较。
■认知测试显示,与之前的相同时间相比,在施加后的第一周内暴露于HV电场的猴子显着减少。此外,GR基因的表达下降,血浆中ACTH激素浓度升高。调查水平的脑MRI图像没有显示任何差异,但是小脑的一部分明显出血。
■被测试的猴子的认知能力,生物,MRI结果显示视觉学习和记忆指数下降。
UNASSIGNED: Today, high-voltage (HV) lines create a pernicious environment for humans living or working in the vicinity and even under these lines. The male rhesus
monkey is used to investigate the effects of fields produced by HV towers. This study examines the function and level of impact in rhesus monkeys\' brains from the cerebellum\'s cognitive, biological, and structural perspective.
UNASSIGNED: Two monkeys have been used, one as a control and the second as a test. The
monkey under test was subjected to a simulated HV electrical field of 3 kV/m, 4 hours a day, for 1 month. Behavioral tests were performed using a device designed and built for this purpose. Concentration analysis of adrenocorticotropic hormones (ACTH) and inspection of glucocorticoid receptor gene\'s (GR) expression were performed by the reverse transcription polymerase chain reaction method. Changes in cerebellar anatomy were examined with magnetic resonance imaging (MRI). All tests were performed before and after the study period and compared with the control
monkey.
UNASSIGNED: Cognitive tests showed a significant reduction for the
monkey exposed to the HV electrical field in the first week after imposition compared with the same time before. Also, the expression of the GR gene decreased, and the concentration of ACTH hormone in plasma increased. Surveying the level of cerebral MRI images did not show any difference, but hemorrhage was evident in a part of the cerebellum.
UNASSIGNED: The tested
monkey\'s cognitive, biological, and MRI results showed a decrease in visual learning and memory indices.
