Figure 2. Adrenal levels of TH are elevated after single, but not recurrent, episodes of hypoglycemia.

(A) TH immunoreactivity was restricted to the adrenal medulla (Med). Scale bar: 100 μm. (B) TH immunoreactivity was increased after 1 episode of hypoglycemia (n = 5). (C). Cumulative intensity distribution of TH immunoreactivity in all cryosections (n = 8–14 per experiment). *P < 0.05 and **P < 0.01, by 1-way ANOVA (B) and Kolmogorov-Smirnov test (C).
