Effects of hemodialysis period on levels of blood trace elements and oxidative stress.

Introduction: As a treatment method for chronic renal failure (CRF), hemodialysis (HD) alters inorganic components containing trace elements. It was shown that decreased renal function is accompanied by insufficient antioxidant systems and/or increased free oxygen radicals. In this study, we aimed to investigate the effects of HD on trace element levels and oxidative stress markers.

The concentration of Zn, Mg and Mn in calcium oxalate monohydrate stones appears to interfere with their fragility in ESWL therapy.

Extracorporeal shockwave lithotripsy (SWL) has remained the preferred method of treatment of urinary stones since its introduction in 1980. Although SWL is classified as a potential first-line treatment for renal stones smaller than 2 cm and its overall success rate is higher than 85% for stone clearance, not all renal calculi are successfully fragmented after SWL. Among the urinary stones, calcium oxalate monohydrate (COM) stone is one of the hardest stones to fragment.

Cadmium exposure from the cement dust emissions: a field study in a rural residence.

The cement dust is one of the causes of pollution in the environment. In the present study, the cadmium concentrations of soil and plant specimens taken from a rural area exposed to cement factory emissions were determined and also the blood concentrations and sensitivity conditions in humans residing in this rural area were investigated. The 108 soil (36 for control) and plant specimens were collected from eight different directions of the cement plant located in Cukurhisar town in Eskişehir city.

Nickel exposure and its effects.

The aim of the study was to determine the nickel concentrations of soil and plant specimens taken from a rural area exposed to cement factory emissions and also to determine the blood concentrations and sensitivity conditions observed in humans residing in this rural area. The study was carried out in Cukurhisar, a town in Eskişehir-Turkey, between May 2000 and March 2001. Beside the 108 soil (36 for control) and plant specimens, which were taken from 8 directions from the cement factory, blood samples of the individuals residing in this area were taken from 258 subjects (258 for control) following a physical examination, and patch tests were also applied.
