Evaluation of oxidative stress and immune parameters of boron exposed males and females

There is growing evidence that boron (B) and B compounds are essential nutrients for animals and humans. Besides, B compounds have been suggested to treat inflammation and oxidative stress. As a part of our "Boron Project II" on B-exposed persons in Bandirma and Bigadic (Turkey) between 2014 and 2017, anti-oxidant/prooxidant and inflammatory parameters were assessed. In this first large-scale human study biomarkers of oxidative stress such as the enzyme activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) and the levels of malondialdehyde (MDA), glutathione (GSH) and 8-hydroxy-2'-deoxy-guanosine (8-OH-dG) were investigated, in relation to B exposure. The immune biomarkers interleukin (IL)-1ra, IL-6, IL-8 and nuclear factor kappa B (NF-kappa B) levels were included. There was no influence of human exposure to B on the parameters of oxidative stress and inflammation.
