Figure 3.
Effects of L-NAME on the basal membrane potential changes in mesenteric small resistance arteries from rats treated with saline or endotoxin. Depicted are the changes in the membrane potential of basal (n=7) and when challenged with L-NAME (0.3 mM, n=5–7) in mesenteric small resistance arterial rings obtained from animals that received injection of vehicle (saline; sham-operated, SOP) or E. coli LPS (10 mg kg−1) for 3 h. Data are expressed as mean±s.e.m. *P<0.05 represents significant differences when compared with the SOP group.
