Effects of different intensities of RTLI on the Endothelium-independent tension of vascular ring. (A) Comparison of relaxation responses to sodium nitroprusside between groups N and H. (B) Comparison of the relaxation response to sodium nitroprusside among groups H, S3qod, and R3qod. (C) Comparison of the relaxation response to sodium nitroprusside among groups H, S3qd, and R3qd. (D) Comparison of relaxation response to sodium nitroprusside among groups H, S6qd, and R6qd. Data are presented as the mean ± SD, n = 10, 9, 7, 6, 8, 7, 7, and 9 in groups N, H, S3qod, R3qod, S3qd, R3qd, S6qd, and R6qd, respectively
