Researchers measured boron content in the human body
The microelements are required for many biochemical and physiological processes of the body. For example, iron takes part in the transfer of electron and breath; zinc is essential for the functioning life-critical enzymes. Until recently, boron has not been considered as a microelement although, in some recent research publications, it has been shown that it is involved in the metabolism of vitamin D and bony tissue including the regulation of the activity of parathyroid hormone.
However, the understanding role of boron has been hindered by the absence of basic knowledge on the normal content of this element in the human body. The missing information has been obtained by the researchers from the People’s Friendship University of Russia (http://www.rudn.ru/en_new/) together with colleagues from other institutions of Russia and Croatia. The amount of boron has been measured in the blood, the composition of those is a reliable indicator showing the substances lacking by the body at the moment as well ax their amount. The measurements have also been done for hairs where the boron and other elements are gradually accumulated and, consequently, one can get a long-term picture of boron storage.
The samples of hairs have been collected from 727 healthy subjects (263 men and 424 women). For 212 randomly chosen subjects (152 women and 80 men), a complete blood count has been performed. The authors note that all the subject are citizens of Croatia mostly from the capital, with an average age of 40−50 years, which have not changed their everyday diet in the course of experiments. The content of boron has been measured in the Moscow Center of Biotic Medicine using the highly-sensible method of inductively-coupled plasma mass-spectroscopy.
The researchers have found out that the content of boron in hairs varies in wide ranges from 0.77 to 6.51 mcg/g for men and from 0.37 to 3.89 mcg/g for women. In the blood, the level has been shown to be notably lower, but the difference between men and women has appeared to be almost negligible: 0,020−0,078 mcg/ml and 0,019−0,062 mcg/ml, respectively. According to the scientists, this denotes that the boron serves the same role in the male and female bodies while the difference of its content in hair is connected with the peculiarities of daily diets usual for different genders.
«To diagnose and correct the failures of boron exchange, one needs to know its normal content in the body,» - a coauthor of the research Andrei Grabeklis. — "Then, it will become evident whether we deal with the lack of, vice versa, with the exceed of this element. This work has been initiated to draw these limits."
The research article is published in the Journal of Trace Elements in Medicine and Biology.
Previously, an international research team has managed to create a 2D boron crystal — a sheet of monoatomic width similar to its structure with graphene.
