The anaesthetic, narcotic effect of magnesium has been discussed since the publication of Meltzer-Auger (1906), but its mechanism has not been clarified. Since then, other investigations have also been performed, but none of the publications has explained the issue. We propose a mechanism analogous to the studies made by Feinstein (1964), who examined organic compounds showing anaesthetic effects. Our view is that magnesium abridges two phospholipids of the opposite sides of the membrane through their phosphate groups. This binding results in membrane rigidity, which makes the ion permeability provided by the ion channel and/or carrier decrease or discontinue, thus the halting of the Na+, K+ and Ca2+ ion flow eventually causes an anaesthetic effect. Another possible pathway is that magnesium ions block the activity of N-methyl-D-aspartate (NMDA) receptor to control the ion channel, which also lowers the permeability of the membrane.

The objective of this study was to investigate magnesium concentrations and load, and to determine their seasonal changes in runoff water from catchments classified as nitrate vulnerable zones. The results indicate that the average concentrations of 12.2 mg Mg⋅dm-3, with fluctuations within the range of 3.3 to 26.2 mg⋅dm-3, and average annual load of 14.3 kg Mg⋅ha-1⋅year-1, with fluctuations within the range of 4.8 to 41.6 kg Mg⋅ha-1⋅year-1, in runoff water from agricultural areas are determined by weather conditions (season), type of drainage system (ditches, drains) and fertilization intensity. In comparison with land drained by a network of drainage ditches, intensive farming in drained areas increases magnesium loss 2.5-fold from 10 kg per hectare of semi-intensively farmed area to 25 kg Mg⋅ha-1 in an intensively farmed area. The highest magnesium loss was reported in the non-growing season, and around 46% of total magnesium load was leached out in the winter. The magnesium loss was minimized during harsh winters and summer draughts (to around 1.2 kg Mg⋅ha-1⋅year-1) due to a seasonal absence of runoffs.

The aim of the paper was to identify the influence of magnesium on the preservation of pathogenic abilities of entomopathogenic nematodes living in soil contaminated with oil derivatives. Entomopathogenic nematodes living under natural conditions in soil or applied to soil as biopreparations for plant pest control are sensitive to soil contamination with heavy metals and oil derivatives. These nematodes do not respond directly by higher mortality but by a decrease in their pathogenic abilities, which adversely affects the success in searching and eliminating pests. A Polish commercial preparation called Owinema SC, containing infective juveniles of Steinernema feltiae Filipjev (Rhabditida: Steinernematidae), was used to test the effect of oil derivatives on pathogenicity and reproduction of entomopathogenic nematodes. Soil was polluted with petrol, diesel oil and used engine oil; the control was soil unpolluted with oil derivatives. Magnesium sulphate was also added (MgSO4∙H2O) in the amount of 160 mg per 1 liter of the suspension. The three oil derivatives in concentrations of: 0.3, 0.6 and 1.0 g or in double doses, i.e. 0.6, 1.2 and 2.0 g were poured over weighted soil batches. The control remained intact. Three replications of each treatment were made. Subsequently, Tenebrio molitor L. larvae used as bait inesct were placed in containers with the suspension. The bait insects were kept in the containers for 7 days, and afterwards they were removed from the soil and taken from the traps in order to check their mortality rate. Furthermore, to test the reproduction ability of entomopathogenic nematodes, dead larvae were moved to “islands” previously prepared according to the Dutky method. The results were presented as the number of entomopathogenic nematodes per 1 dead larvae of Tenebrio molitor L.

Współczesny sport wyczynowy często wymaga od zawodników ogromnego wysiłku, który przekracza ich maksymalne możliwości fizyczne i umysłowe. Sportowcy często mają złe nawyki żywieniowe i spożywają suplementy diety zawierające magnez i witaminę B6 w celu uzupełnienia niedoborów żywieniowych. Celem badań było oznaczanie zawartości magnezu i witaminy B6 w całodziennych racjach pokarmowych sportowców wyczynowych w Polsce i ocena uzasadnienia suplementacji diety. Zawartość magnezu i witaminy B6 oznaczano w 62 zebranych i 12 odtworzonych całodziennych racjach pokarmowych profesjonalnych biegaczy. Do oznaczania magnezu i witaminy B6 wykorzystano odpowiednio metodę spektroskopii absorpcyjno atomowej i HPLC. Analizowane całodzienne racje pokarmowe kobiet dostarczały 256 ± 111 mg magnezu i 2,04 ± 0,63 mg witaminy B6, podczas gdy całodzienne racje pokarmowe mężczyzn dostarczały 284 ± 58 mg magnezu i 2,12 ± 0,68 mg witaminy B6. Analiza przeprowadzona z udziałem programu komputerowego wykazała 159-181% wyższą zawartość magnezu i witaminy B6 w porównaniu do wartości oznaczonych laboratoryjnie. Wyniki badań wykazały, że analizowane całodzienne racje pokarmowe sportowców dostarczały zbyt małych ilości magnezu, co może uzasadniać suplementację diety tym pierwiastkiem. Całodzienne racje pokarmowe pokrywały natomiast dzienne zapotrzebowanie (RDA) na witaminę B6, dlatego też suplementacja diety tym składnikiem nie była uzasadniona.
