Figure 1. Oral glucose tolerance test in LZR and OZR with and without apocynin treatment.
The fasting glucose levels were not significantly different between LZR and OZR both control and apocynin-treated groups. After gavage with a glucose solution, OZR exhibited significantly higher hyperglycemia compared with LZR in both control and apocynin-treated group (*, p < 0.05; #, p < 0.05). Apocynin treatment has no effect on insulin sensitivity in both LZR and OZR. (LZR control, n = 5; OZR control, n = 5; LZR apocynin, n = 4; OZR apocynin, n = 6).
