Effectiveness of NH4+ substituting for K+ (expressed as ratio of Na+/NH4+-ATPase activity to Na+/K+-ATPase activity) to induce Nka activities from the brain of M. musculus, or from the brain of M. albus kept in freshwater or exposed to 50 mmol l−1 NH4Cl for 6 days.

Values are means ± S.E.M. (N = 5).

Means not sharing the same letter are significantly different, P<0.05.
