Abstract

The oestrone loading test was carried out on fifteen patients suffering from fluorine liver damage. Three pattern curves of the oestrogen fraction (oestrone, 17?-oestradiol and oestriol) excretion in the urine were established. Our data show that there were disturbances in oestrogen metabolism in patients with fluorine liver damage.

  • Evaluation of multi-endpoint assay to detect genotoxicity and oxidative stress in mice exposed to sodium fluoride

    Fluoride compounds are naturally present in soil, water and food. The objective of this study was to investigate the genotoxic and oxidative damage induced by chronic fluoride exposure on mammalian cells in vivo. For this purpose, the genotoxic potential was investigated in bone marrow cells by the micronucleus test, chromosome

    INTRODUCTION: Fluorides are common in the environment and are absorbed mostly in the stomach and gut, it can easily move through cell membranes and its accumulation can cause harmful effects in skeletal and soft tissues. One of the most important F- accumulation sites is the liver. The aim of this
