Opis:
Epilepsy is a common neurological disorder. It affects 50 million people worldwide, over half of which are children. Many children who suffer from epilepsy are also affected by metabolic disorders, characterized by obesity as well as intolerance and deficient transport of glucose. Recently, many researchers have indicated chromium (+3) as an essential trace mineral which probably plays an important role in metabolism of glucose and insulin. There are no data about chromium alterations in the body of epileptic patients. The purpose of this study was to find possible correlation between chromium (+3) concentration and the glucose level in children with epilepsy. Material and methods: Twenty-three untreated epileptic children with idiopathic generalized tonic-clonic seizures (9 girls and 14 boys) aged 13.4±2.7 years and 25 healthy children (sex-age-matched) served as a control were recruited to this study. The chromium blood and serum concentrations were determined as well as serum glucose level. Results: There were no statistically significant differences between epileptic and healthy children in the mean chromium (+3) blood concentration as well as according to sex in both analyzed groups of children. The mean serum chromium concentration in epileptic children was significantly lower than in healthy subjects generally (p<0.001), as well as in boys group (p<0.001) and girls (p<0.001). Although, the negative statistically significant correlation between serum glucose and chromium concentrations was found in epileptic children (p<0.01), we have not found so associations in whole blood and in healthy children. Conclusions: Our research has shown that during epilepsy the concentration of serum chromium was lower than in healthy subjects what was associated with glucose abnormalities. These preliminary results suggest that the detail research on the chromium in epilepsy are necessary.

Opis:
Hypocalcaemia and hypomagnesaemia in patients with eating disorders are poorly identified, same as in animal models of these diseases. The purpose of the present study was to assess the concentration of calcium and magnesium in the serum, brain tissue and femoral bone of food restricted female Wistar rats. Material and Methods: 48 rats (8-weeks old, 199 ± 18 g) were divided into 6 groups (n = 8): the control group (C) were fed ad libitum, with measurements of daily intake, as a baseline for the amount of intake calculation for the other groups. The remaining five were testing groups: R50 – received half a portion of the diet eaten by C. The other groups were fed with a 100% of the diet eaten by C, but in a different model of food restriction: RI-IV – one-four day/s feeding, followed by one-four day/s starvation, throughout the eight weeks of the experiment. After wet mineralization of tissues, the calcium and magnesium concentrations were measured via the AAS method. Results: The calcium concentrations in serum and brain were unchanged, while the concentration of calcium in bone samples was significantly higher in food deprived rats compared to control groups rats. The influence of different models of food deprivation was observed in magnesium concentrations in the tissues studied. Generally, the levels of this mineral were significantly lower in all tissues in rats exposed to starvation than in control. Conclusions: The results of the current study suggest that although the amount of food intake was similar in all starvation models, food deprivation affects the management of calcium and magnesium in different ways. The competitiveness between these minerals, under food restriction, probably works to the benefit of calcium. This may lead to increased hypomagnesaemia and its subsequent implications.
