Figure 2From: Significance of KATP channels, L-type Ca2+ channels and CYP450-4A enzymes in oxygen sensing in mouse cremaster muscle arterioles In vivoEffects of DMSO were evaluated. During the control, high oxygen tension constricted the arterioles, whereas low oxygen tension dilated them. Vessels responded equally in the presence or absence of 0.3% DMSO. There were no statistically significant difference in arteriolar diameter between the control and 0.3% DMSO during low oxygen tension (p = 0.709) and during high oxygen tension (p = 0.188).Back to article page
