Relationship between neurological outcome and early oxidative changes in erythrocytes in head injury patients

Background: Experimental data indicate that destructive oxidative events reach their peak within the first 24 h after trauma in head injury (HI) and that brain damage occurring due to this impact can be the cause of death or irreversible permanent disabilities in affected patients.

Methods: Venous blood samples were obtained from 50 HI patients within 24 h of trauma onset and from 30 age- and sex-matched normal controls (NC)...

Keywords: erythrocytes, glutathione, lipid peroxidation, outcome, reactive oxygen species

Characteristics of prolinase against various iminodipeptides in erythrocyte lysates from a normal human and a patient with prolidase deficiency

The effect of various amino acids and MnCl₂ on prolinase activity in erythrocyte lysates from a healthy individual and a patient with prolidase deficiency was investigated...

Is idiopathic recurrent calcium urolithiasis in males a cellular disease? Laboratory findings in plasma, urine and erythrocytes, emphasizing the absence and presence of stones, oxidative and mineral metabolism: an observational study

Background: The site of origin of idiopathic recurrent calcium urolithiasis (IRCU) – a disorder characterized by stones composed of calcium oxalate (CaOx) and/or calcium phosphate (CaPi) – is uncertain, because in urine such risk factors for stones as disturbed Ox, Ca and Pi are not regularly observed...

Keywords: antioxidant deficit, erythrocytes, idiopathic calcium urolithiasis, mineral metabolism, molar calcium/phosphate, Plasma, stone absence or presence, urine

Alterations in anti-oxidative defence enzymes in erythrocytes from sporadic amyotrophic lateral sclerosis (SALS) and familial ALS patients

Background: Overproduction of nitric oxide (NO) and hydrogen peroxide (H₂O₂) may be an important factor in the pathogenesis of amyotrophic lateral sclerosis (ALS)...

Keywords: amyotrophic lateral sclerosis, anti-oxidant defence enzymes, copper zinc superoxide dismutase (CuZn SOD), erythrocytes
