Rats were treated as described in figure legend 4. Results are expressed as percentage (mean ± S.E.M.) increase above baseline (Figure 6a). *P<0.05 vs. corresponding group pretreated with NT69L; #P<0.05 vs. saline/saline group (alcohol-red; nicotine-green; alcohol+nicotine-blue). Average percentage change above baseline is shown in Figure 6b. *P<0.05 vs. corresponding group pretreated with NT69L; #P<0.05 vs. saline/saline group.
