Assessment of serum ionized magnesium levels in healthy volunteers, in patients with coronary artery disease and/or hypertension and in hypertension alone.

We examined ionized magnesium concentration by blood analysis in patients with hypertonia arterialis, ischemic heart diseases, both of them and in a control group. Slighty lower mean serum ionized magnesium concentration was found in the study group hypertonia arterialis when compared to the control group. In patients both group "B" with coronary artery diseases and group "C" with hypertonia arterialis + ischemic heart diseases, mean serum ionized magnesium concentrations were higher then in the control group, the differences were statistically significant.

[Behavior of selected bio-elements in women with osteoporosis]. / Zachowanie sie wybranych biopierwiastków u kobiet z osteoporoza.

The purpose of this study was to evaluate the concentration of calcium, magnesium, zinc and copper in serum, urine and hair in women with osteoporosis, and to find out whether deficiency of these bioelements correlates with BMD. The concentration of calcium, magnesium, zinc and copper was assessed in 80 women aged 40-68 years. The women had been menopausal for 9.3 years and had never undergone hormone replacement, drugs therapy or mineral supplementation. The bone mass density (BMD) in lumbar spine L2-L4 was measured in 80 postmenopausal women using dual energy X-ray absorptiometry. According to BMD values all women were divided into two groups. The first group (50 persons) comprised women with osteoporosis. The second group included 30 women without osteoporosis. After an overnight fasting the levels of calcium, magnesium, zinc and copper in serum, in urine and in hair were measured by AAS. Concentration of osteocalcin and ionized calcium as well as magnesium was also measured in serum. Calcium, magnesium, zinc and copper excretions were expressed as a ratio of urinary creatine. Data were compared with Wilcoxon-Mann-Whitney's test and significance was assessed at p < 0.05. The regression and correlation analysis was performed between BMD and level of bioelements. It was determined that the mean serum osteocalcin in the examined group (2.067 ng/ml) was higher than in the control group (1.602 ng/ml). It was also disclosed that there was a lower level of total (Tab. 1) and ionized magnesium in serum (Tab. 2) and reduced excretion of this element in urine (Tab. 4) of fasting women with osteoporosis. The concentrations of calcium, zinc and copper in serum (Tab. 1) and in urine (Tab. 4) in both groups were similar to laboratory normal range. Hair calcium and magnesium levels in examined group were lower in comparison with the control group (Tab. 3). Concentrations of zinc and copper in hair were similar in both groups (Tab. 3). The study found out that women with osteoporosis displayed magnesium deficiency. The results showed that highly significant correlation existed between magnesium and calcium. No significant relationship between BMD and the concentration of bioelements was observed.

[Deficiency of certain trace elements in children with hyperactivity]. / Wystepowanie niedoborów wybranych biopierwiastków u dzieci z nadpobudliwoscia.

The magnesium, zinc, copper, iron and calcium level of plasma, erythrocytes, urine and hair in 50 children aged from 4 to 13 years with hyperactivity, were examined by AAS. The average concentration of all trace elements was lower compared with the control group--healthy children from Szczecin. The highest deficit was noted in hair. Our results show that it is necessary to supplement trace elements in children with hyperactivity.

[The level of calcium, magnesium, zinc and copper in blood serum in children and young people between 5 and 18 years of age]. / Poziom wapnia, magnezu, cynku i miedzi w surowicy krwi u dzieci i mlodziezy w wieku 5-18 lat.

The blood serum of 420 children and young people between 5 and 18 years of age was examined to appoint the content of calcium, magnesium, zinc and copper in it. The examination was realized by AAS method. The calcium level was from 54.16 mg/l to 594.28 mg/l; an average was 148.66 +/- 64.61 mg/l. The magnesium level was from 7.78 mg/l to 66.26 mg/l; an average was 21.84 +/- 6.36 and was higher than data in literary output for children from other regions of Poland. The zinc level was from 0.19 mg/l to 2.94 mg/l, on an average 0.92 +/- 0.30 mg/l. The copper level was from 0.23 mg/l to 2.56 mg/l; average was 1.03 +/- 0.34 mg/l. The almost shortages in these bioelements were in children between 10 and 14, the least shortages were in children between 5 and 9. There were most of all children with high zinc level in blood serum in 10-14 years old group.
