Decreased Erythrocyte NA⁺,K⁺-ATPase Activity and Increased Plasma TBARS in Prehypertensive Patients

Figure 2

Na⁺,K⁺-ATPase activity (nmol Pi/mg protein/min) negatively correlates with TBARS content only when analyzed with all prehypertensive (■) and normotensive (⚫) subjects (𝑟=−0.6; 𝑛=16) (a) and diastolic blood pressure only in hypertensive subjects (b). 𝑃<0.05 by the Pearson’s correlation coefficient (𝑟=−0.84; 𝑛=8).
