Figure 3. Na⁺–K⁺-ATPase in fetal llama brain cortex submitted to 24 h of hypoxaemia.

A, Na⁺–K⁺-ATPase activity; B, representative ouabain binding saturation curves; C, calculated maximal binding (B_MAX). Values are expressed as means ±s.e.m.; n = 5 for each group; *P < 0.05, unpaired Student's t test. Normoxaemia (filled bars, •) versus hypoxaemia (open bars, ○).
