人体必需的某些微量元素如锌、铜和铁等是一些金属酶的重要构成成分,它们直接或间接地参与儿茶酚胺及某些多肽与激素的合成与降解,从而影响血压。而一些有毒的微量元素特别是其中的铅和镉,与高血压的关系尤为密切。本文拟就近年来国外在这一研究领域中的概况和进展加以扼要介绍和评述。 Some trace elements essential to human body such as zinc, copper and iron are important constituent elements of some metalloenzymes. They are directly or indirectly involved in the synthesis and degradation of catecholamines and certain polypeptides and hormones, thereby affecting blood pressure. Some of the toxic trace elements, especially lead and cadmium, are particularly associated with high blood pressure. This article intends to briefly introduce and review the overview and progress made by foreign countries in this field in recent years.
