[Na⁺]_br and [K⁺]_br in different regions of ischemic brain.

Region		[Na⁺]_br (mEq/kg wet weight)		[K⁺]_br (mEq/kg wet weight)

		Rostral	Caudal	Rostral	Caudal
1. Dorsal ischemic edge	ipsilateral	76±5	87±4	40±18	30±15
	contralateral	49±5	51±5	100±17	100±16
2. Central ischemic core	ipsilateral	68±6	73±4	70±17	80±13
	contralateral	49±4	51±4	100±13	113±9
3. Ventral ischemic edge	ipsilateral	100±4	95±6	50±19	40±16
	contralateral	54±4	60±3	100±19	110±13

[Na⁺]_br and [K⁺]_br (mean ± SD) were estimated by ²³Na MRI and histochemical K⁺ staining, respectively, at the rostral (bregma −0.4 mm) and caudal (bregma −3 mm) coronal brain levels at 4.4 h after MCAO in rat #5. ROI placement is shown in Fig. 3. The SD values resulted from averaging over pixels within ROIs.

For every comparison of the ipsilateral and corresponding contralateral ROIs, P < 0.05.
