Fig. 1.
Flow-induced dilation of coronary arterioles of normal-salt (NS, n = 5; A) and low-salt (LS, n = 7; B) diet dogs in the control condition and after incubating vessels with apocynin (APO, 10−5 M), or apocynin plus Nω-nitro-l-arginine methyl ester (l-NAME, 3 × 10−4 M) for 30 min. Changes in diameter were normalized to passive diameter (PD) of the vessels. *Significant difference from the curve of APO. C and D: sodium nitroprusside (SNP) and adenosine (ADO)-induced dilations in coronary arterioles of NS and LS dogs.
