[Balance of iron and copper in cadets of military school during physical exercise and next-day rest at different times of the year].

According to examination, with the help of emission spectrum analysis method, of 24 cadets-athletes of different specialization it was determined that during physical exercise in summer and in winter loss of ferrum and copper with excrements exceeded the intake if these microelements with food. The next day rise of impaction of microelements and decrease of excretion. But despite the positive balance of ferrum and copper, spend of these microelements during physical exercise wasn't compensated for the day of rest.

[S100B protein and autoantibodies to S100B protein in diagnostics of brain damage in craniocerebral trauma in children].

Levels of antibodies AB (AB) to S100B and S100B protein were studied in the blood serum of children with different severity and outcomes of traumatic brain injury (TBI) from the 1st to 15-75th days after TBI. Severity and outcomes were assessed using the Glasgow Coma Scale (GCS). Patients were stratified by outcomes into the following groups: complete recovery (group 1), moderate disability (group 2), high disability (group 3), vegetative state (group 4) and fatal outcome (group 5).

[Autoantibodies to glutamate receptors and metabolic products of nitric oxide in blood serum of children in the acute period of brain trauma].

Autoantibodies (AB) to glutamate receptors of AMPA (Glur1) and NMDA (NR2A) types and nitric oxide metabolites, nitrates and nitrites (NOx), were studied in the blood serum of children with brain trauma of different severity. The level of both AB types increased from the 1st to the 10th day after trauma. The level of NMDA (NR2A) AB was higher comparing to AMPA (Glur1).

[Providing athletes with trace elements during intensive exercise].

On the day of 30-km cross-country running, the content of iron, copper, and manganese in the diets of highly skilled adult athletes was found to be in the lower normal physiological range for those who do not go in for sports. During intensive exercise the intestinal and renal excretion of these substances was much greater than their dietary intake. The balance of all three substances was negative.
