Blood plasma and saliva levels of magnesium and other bivalent cations in patients with parotid gland tumors.

The plasma and saliva cations in parotid malignant tumors of stages II-III were studied in 31 patients before surgical therapy and in 27 control group volunteers. The magnesium (t-Mg), calcium (t-Ca), copper (t-Cu) and zinc (t-Zn) concentrations in plasma were determined, and t-Mg and t-Ca in saliva. Our results showed that salivary and plasma t-Mg concentrations were significantly higher in patients with parotid malignant tumors in comparison to control group (saliva: 0.

Magnesium influence on nicotine pharmacodependence and smoking.

We followed the magnesium effect (Magne B(6)R, Sanofi-Synthelabo) with internal administration in 53 adult neurotic smoking patients (more than 10 cigarettes/day) of both genders admitted into psychiatric hospital. The nicotine dependence was assessed by the Fagerstrom test, initially and after 28 days of magnesium intake. Plasmatic magnesium level was determined before any therapy and at 28 days.

Experimental studies concerning the possible involvement of adenosine in maintaining the hydroelectrolytic balance.

The study focused on the effects of intracerebroventricular (i.c.v.

[The effects of the intraventricular administration of captopril on water and ion metabolism in the rst].

The effects of the conversion enzyme on the hydroelectrolytic balance in adult rats, maintained in standard lab conditions have been followed. The administration protocol for the conversion inhibitor (captopril) produced a blocking of the transformation of angiotensin I in angiotensin II only at the level of the cerebral structures, during the whole period of the treatment (40 micrograms/kg x 3/24 hours). Following the intracerebroventricular (ICV) administration of captopril, the fluid ingestion decreased diuresis and urinary elimination of Na+ and Ca++ increased.
