[The Effect of the Antioxidant Drug U-74389G on Magnesium Levels During Hypoxia-Reoxygenation Injury in Rats].

OBJECTIVE

The aim of this experimental study was to examine the effect of the antioxidant drug U-74389G in a rat model of hypoxia-reoxygenation using the previously established protocol. Effects of treatments were evaluated by magnesium (Mg2+) levels in blood.

METHODS

Non-randomized controlled study was performed. Mg2+ levels were determined in 60 min (groups A and C) and 120 min (groups B and D) after starting the reoxygenation. Groups A and B received no drugs, whereas rats from groups C and D were administered with U-74389G.

RESULTS

40 rats 16-18 weeks old of a mean weight of 2312 g were employed in the study. It is demonstrated that U-74389G administration did not alter the Mg2+ levels (decrease in Mg2+ concentration was 0.28±2.75%; p=0.917). Reoxygenation non-significantly increased the Mg2+ levels by 4.27±2.66% (p=0.107). Together, the U-74389G administration and reoxygenation non-significantly increased the Mg2+ levels by 0.36±1.64% (p=0.823).

CONCLUSION

U-74389G administration, alone or in concert with reoxygenation did not significantly affect Mg2+ level in blood after experimental hypoxia in rats.
