FIGURE 2.
Top, effect of 10 μm apocynin (an NADPH oxidase inhibitor) on the stimulatory effect of angiotensin II on O production by rat thick ascending limbs. Rat thick ascending limbs were incubated with 1 nm angiotensin II for 10 min in the presence or absence of apocynin and superoxide production measured. n = 5 per group. Bottom, effect of 1 nm angiotensin II for 10 min on O
production by thick ascending limbs isolated from wild-type and p47phox knock-out mice (p47phox−/−). n = 4. Ang II, angiotensin II.
