Bryophytes: a powerful source of biologically active compounds
Bryophytes are generally considered the first plants appeared on the Earth. Taxonomically, they are placed between Algae and Pteridophytes. The medicinal traditional use of bryophytes has been documented for a long time in many countries. Bryophytes contain numerous potentially useful compounds and strong antioxidative enzymatic machinery, which help them to cope up with extreme climates and stresses, and, in several cases, the total antioxidant amount was found higher than in other antioxidant common sources even if not yet fully known. Thus, a positive correlation between the folklore use and the scientific evaluation could generate an alternative source of novel medicinal compounds, whic…
BIOLOGICAL MONITORING AND NEPHROTOXIC SUBSTANCES
A long latent period elapses between the exposure to toxic substances, injuring the kidney and the development of advanced stages of kidney failure. As regards the biological monitoring of people exposed to nephrotoxic substances, we need precocious indicators of renal damages, able to avoid the onset of nephropathies. The aim of this study has been underlining these biological markers. We have considered two groups of workers: the first one made up of people exposed to aromatic poly cyclic hydrocarbons (APH). The second one was made up of people exposed to welding smokes. We have examined 240 male subjects. The entire sample has been subjected to the dosing of the following biological indi…
