Cifuente F, Bravo J, Norambuena M, Stegen S, Ayavire A and Palacios J. Chronic Exposure to Arsenic in Tap Water Reduces Acetylcholine-induced Relaxation in the Aorta and Increases Oxidative Stress in Female Rats. Int J Toxicol. 2009;28:534-541. (Original doi: 10.1177/1091581809345924).

In the November/December issue of International Journal of Toxicology, the vertical title that appeared in Figure 3, on page 538 is incorrect. It should have read “% SNP-induced relaxation”.

In addition, the headings of the columns that appeared in Table 3 on page 540 were incorrect. The correct version of Table 3 is provided below.

Table 3.

Mean Blood Pressure (MAP), Pulse Pressure (PP), Heart Rate (HR), Cardiac Output (CO), and Peripheral Resistance (PR) of Controls and Arsenic-Treated Rats

	2-month-old Control	2-month-old Arsenic-treated	7-month-old Control	7-month-old Arsenic-treated
MAP, mm Hg	124 ± 2	122 ± 3	136 ± 5	148 ± 7 b
PP, mm Hg	37 ± 5	36 ± 2	36 ± 2	19 ± 1 c,g
HR, beats/min	352 ± 16	349 ± 12	315 ± 16	297 ± 14 b
CO, % change a	–	–	–26	–146 e ; –95 f
PR, % change a	–	–	27	64 d ; 51 b

Values are mean ± standard error of the mean.

CO = stroke volume × HRH; PP ~ stroke volume; PR = MAP/CO.

^a Percentage change vs 2- and 7-month-old controls.

^b P < .05

^c P < .001 vs. 2-month-old control and arsenic-treated.

^d P < .01

^e P < .001 vs. 2-month-old control.

^f P< .01

^g P< .001 vs. 7-month-old control.
