Figure 4. Group mean (±s.e.m.) CVC data from protocol 2.

Values are from the plateau in skin blood flow during whole body heating. Treatment with an H2 antagonist did not significantly reduce CVC compared with control. l-NAME sites and sites treated with l-NAME plus cimetidine were significantly reduced compared with control and cimetidine only sites but were not different from each other. *P < 0.05 versus control sites; †P < 0.05 versus cimetidine only sites.
