Figure 1From: Decreased pain threshold and enhanced synaptic transmission in the anterior cingulate cortex of experimental hypothyroidism mice Levels of T3 and T4 in serum. (A) Timeline for experiment. Mice were treatment with MMI and KClO4 for 4 weeks, then followed with T3 or T4 supplementation for 2 weeks. Detections were performed during Day 43 and Day 45. Levels of T3 (B) and T4 (C) in saline control, vehicle-, T3-, and T4-treated HT mice. n = 5 in each group. * p < 0.05, ** p < 0.01 compared with naïve saline control; ## p < 0.01 compared with vehicle-treated HT mice.Back to article page
