[Ionic calcium and magnesium from pharmaceutical product BEROCCA effects on neuromuscular excitability].

The important physiological role of calcium and magnesium ions is all over recognised, about a lot of enzymatic reactions. Magnesium deficit produce neuromuscular hyper-reactivity, psychic reactions, functional hypoparathyroidism, increase of K+ channels membranes permeability, while hypermagnesemia decrease Ach release from neuromuscular synapsis, with post-synaptic excitability decreasing. Using BEROCCA (Hoffman la Roche) 1 cp/day, 30 days at the teenagers with behaviour troubles and at a goup of pregnant women (trimester I-III) with paresthesia, irritability, sleeplessness, we observed an improve of clinical signs, increasing plasma Ca2+ and Mg2+.

[Consideration on high gradient magnetic separation of red cells].

The red cells exhibit a proper magnetism due to hemoglobin. In a prototype of high gradient magnetic separator equipped with an ordered ferromagnetic matrix, a set of experiments with blood to determine the influence of the process parameters on the efficiency of the erythrocytes capture was realized. Dependent on the values of the magnetic induction (1.

[Normal and pathologic implication of cytokines].

Cytokines involved in the immune process proof, also, the neurotransmitter role, being synthesized by various cells of the body, with specific genes participation. Cytokines can act on the some membrane receptor like the neurotransmitters, and they can produce diverse biological effects. Pro-inflammatory, anti-inflammatory or haematopoetic cytokines as those in the central nervous system can be identified by immunoassay and bioassay methods.

[EEG patterns in alcohol withdrawal syndrome].

The cerebral motor and cognitive behavior is obviously altered by chronic alcoholism, which generates significant morphological and biochemical changes. In turn, alcoholic withdrawal improves the cerebral blood supply, the psychological and motor behavior and the EEG appearance, especially in young alcoholics. Our study also underlines that alcoholic women develop a late improvement of the clinical and bioelectrical condition during the alcoholic withdrawal.
