Razlike u koncentracijama bioelemenata mogu igrati ulogu u patogenezi shizofrenije. Nutritivna deprivacija u ranoj fazi života povećava rizik za razvoj shizofrenije, a oksidativni stres i poremećaji mišljenja koji su zajednički osobama sa shizofrenijom mogu biti posljedica promjena u razini određenih metala. Veći broj istraživanja potvrdio je hipot...

The transfer of lead 203 (203Pb) and calcium 47 (47Ca) from mother to fetuses and litter was examined 48 hours after a single intravenous application of both radioisotopes to rats on the 18th day of pregnancy and on the fourth and 15th day of lactation.
Lead (Pb) transfer from mother to litter was investigated at the late stage of lactation after a single intraperitoneal injection of 2.0 μg Pb/ml marked with 203Pb . After 48 hr almost 20% of the maternal dose of 203Pb was found in the litter, and about 0.6 and 0.2% of the injected dose was found in the liver and kidneys of suckling rats, respectiv...
