Group	Magnesium concn in:		Calcium concn in:		Tocopherol concn in plasma (nmol/ml)
	Plasma (mmol/liter)	Cartilage (mmol/kg, dry wt)	Plasma (mmol/liter)	Cartilage (mmol/kg, dry wt)
A, standard diet	0.83 ± 0.10	27.7 ± 6.7	2.74 ± 0.18	683 ± 305	93.6 ± 21.1
B, vitamin E-enriched diet	0.88 ± 0.08	24.7 ± 4.2	2.77 ± 0.19	613 ± 333	146 ± 27.4c
C, Mg2+-enriched diet	1.28 ± 0.23c	33.3 ± 6.4	2.79 ± 0.11	595 ± 317	88.3 ± 21.8
D, vitamin E- and Mg2+-enriched diet	1.15 ± 0.20c	35.5 ± 10.4b	2.81 ± 0.11	763 ± 449	158 ± 25.8c

^aValues are means ± SDs for 12 34-day-old Wistar rats per group.

^bP, <0.05 for comparison with value for standard-diet group (A); Dunnett t test (ANOVA).

^cP, <0.01 for comparison with value for standard-diet group (A); Dunnett t test (ANOVA).
