Effect of streptozocin-induced diabetes (STZ-D) and MgSO₄ supplementation to diabetic rats on water, food and Mg intakes and urine excretion at week 4 of the experiment

Parameter	Non-diabetic	Non-suppl. STZ-D	MgSO4-suppl. STZ-D
Water intake (ml (24 h)−1)	35.22 ± 2.36	376.6 ± 32.87***	214.4 ± 30.87***,###
Urine excretion (ml (24 h)−1)	12.45 ± 1.51	300.1 ± 24.16***	184.4 ± 25.23***,##
Food intake (g (24 h)−1)	30.7 ± 1.83	54.66 ± 3.67**	42.06 ± 6.21
Total Mg intake (mg (24 h)−1)	61.40 ± 3.66	109.32 ± 7.34***	147.58 ± 1.58***,###

Values are expressed as means ±s.e.m. (n = 10/group). Statistical analysis was performed by one-way ANOVA followed by a Tukey–Kramer test.
