It is known that alcohol possesses embryotoxic, teratogenic, neurotoxic and other effects. Alteration of the trace element and mineral metabolism can be one of the triggering mechanisms of metabolic changes during an alcoholic intoxication. The aim of the recent study was to compare the profiles of elements in brain structures of matured offspring which were born by female rats exposed and non-exposed to alcohol before conception. A decreasing tendency in the levels of all detected macro and trace elements in four brain structures was observed. The most prominent changes were found in the brain cortex. Experimental data show that short term consumption of alcohol by female rats before pregnancy alters the distribution of macro and trace elements in the offspring's brain structures.
众所周知,酒精具有胚胎毒性、致畸性、神经毒性等作用。微量元素和矿物质代谢的改变可能是酒精中毒期间代谢变化的触发机制之一。最近的研究目的是比较在受孕前暴露于酒精和未暴露于酒精的雌性大鼠所生成熟后代的大脑结构中元素的分布情况。在四个大脑结构中,所有检测到的常量和微量元素的水平都呈现出下降的趋势。最明显的变化发生在大脑皮层。实验数据表明,妊娠前雌性大鼠短期饮酒会改变后代大脑结构中常量和微量元素的分布。
