Aim of study. To find correlation between the umbilical serum cord magnesium concentration in a group of newborns without antenatal exposition to magnesium sulphate and the neonatal outcome as well as to compare the neonatal outcome of babies with maternal magnesium sulphate treatment. Results. In a group of 82 newborns (31-34 GA; birth body weight <1500 g) the umbilical cord serum magnesium concentrations was assayed. Three subgroups of neonates were set apart: first group (N) with a normal magnesium level (n=28), the second group (n=19) with magnesium concentration <0.75 mmol/dl (D), and the third group (Mg) consisting of 35 newborn antenatally exposed to magnesium sulphate. These groups were similar (no statistical significances) in terms of birth body weight, gestational age, Apgar score and umbilical blood pH. Gradual decrease in magnesium concentration in relation to increase of gestational age was observed. In groups: D, N, Mg, gradual reduction of hospitalization time (p<0.05), risk of death, time of respiratory support, time of oxygen therapy, rate of bronchopulmonary dysplasia, periventricular leucomalation (p<0.05) were observed respectively. Likewise, a rate of serious neurological complication (IVH/ PVL) in group D was higher in comparison to groups N and Mg (although without statistical sig-nificances). Conclusion. Our results confirm that umbilical cord magnesium concentration in VLBW neonates have an influence on neonatal outcome. Although it is premature to recommend ordering maternal magnesium sulphate treatment to improve neonatal outcome, in our opinion the data presented here should at least induce magnesium concentration monitoring in pregnant women and magnesium deficiency correction.

The blood levels of parathyroid hormone (PTH), calcium, phosphorus and magnesium were examined in 122 cows, which included healthy cows as well as cows with osteomalacia and paresis. Levels of PTH were determined in vitro using IMMULITE analyzer, levels of macroelements - using the automated “Eos-Bravo” analyser with Hospitex reagents. The blood level of PTH ranged from 1.7 to 7.5 pmol/l in healthy cows and from 3.95 to 20.19 pmol/l in sick cows. The highest and most significant increase in blood PTH level (up to 18.31 ± 1.88 pmol/l) was found in cows with parturient paresis. The blood serum levels of PTH in healthy cows changed depending on age and on the physiological status, being significantly lower in cows 2-4-years-old compared with cows 8-years-old and over. The levels of PTH were significantly higher in cows-in-calf and heifers-in-calf compared with cows of the lactation period. Higher levels of PTH were found during the winter than in the summer. The blood level of PTH correlated inversely with the level of calcium in cows with osteomalacia (r = -0.89) and with parturient paresis (r = - 0.49-0.61). The blood serum PTH levels were significantly increased in all groups of cows (p<0.05) on the day of parturition and one day after parturition compared with the measured PTH level 5 days before parturition. Vitamin D (injected 3-5 times) administered during the last days before calving effectively increased the levels of calcium, phosphorus and PTH.

W pracy oceniono poziom magnezu w ślinie osób chorych na stwardnienie rozsiane. Badanie biochemiczne wykonano również w grupie kontrolnej. Na podstawie przeprowadzonych badań stwierdzono obniżony poziom magnezu w ślinie osób chorych w porównaniu z osobami zdrowymi. Wyniki badań mogą sugerować pewien związek ze stwardnieniem rozsianym.

In this study the level of magnesium in saliva of patients with multiple sclerosis was analyzed. Biochemical analysis of saliva was carried out in the control group, too. On the basis of our examination the lower level of magnesium in saliva of SM patients in comparison to control group was observed. The results of our examination may suggest that lower magnesium concentrations in saliva could be connected with multiple sclerosis.

Badania przeprowadzono w surowicy krwi uzyskanej z Regionalnego Centrum Krwiodawstwa w Szczecinie. Uwzględniając płeć i wiek dawców podzielono na następujące grupy: K1 - kobiety w wieku od 19 do 25 lat, K2 - kobiety w wieku od 26 do 43 lat, M, - mężczyźni w wieku od 19 do 25 lat, M2 - mężczyźni w wieku od 26 do 43 lat. W materiale badawczym oznaczono stężenie magnezu, wapnia oraz triglicerydów. W opracowaniu statystycznym wyników określano wpływ magnezu i wapnia na poziom triglicerydów w surowicy krwi badanych osób. Na podstawie uzyskanych wartości współczynników korelacji Pearsona (r) zależność istotną przy umiarkowanej korelacji stwierdzono jedynie między poziomem magnezu a triglicerydów w grupie mężczyzn starszych (M2).

Human blood serum received from the Regional Blood Donation Centre in Szczecin was analysed. Donors were divided into four groups according to the sex and age: K1 (women aged 19 - 25), K2 (women aged 26 - 43), Ml (men aged 19 - 25), M2 (men aged 26 - 43). Magnesium, calcium and triglycerides concentrations in the blood serum of donors were determined. Statistical influence of Mg and Ca on the triglycerides level was assessed. The values of Pearson's correlation coefficients (r) obtained indicated only one statistically significant relationship (at moderate correlation) occurring in M2 group (men aged 26 - 43).

Deionized water orally dosed, ad libitum dosage were tested on rats for 90 days period. The purpose of the experiment was the estimation of changes in aqua-electrolytic economy of tested animals. Statistically relevant reduction of sodium, potassium, magnesium level in blood serum as well as in urine. In blood serum there were observed also statistically increase of calcium concentration whereas in urine calcium concentration descended. The results prove that drinking deionized water can cause similar unfavorable influence on mineral economy in human system.
