CRHR2 and myeloid sarcoma: In hippocampal tissue samples, the receptors of corticotrophin‐releasing hormone Crhr1 and Crhr2 were up‐regulated in the MS group (0.7508 ± 0.2612 and 0.8534 ± 0.1876, respectively) compared with group C (0.0908 ± 0.0206, t = 2.78, df = 9, p < .05 and 0.2400 ± 0.0521, t = 3.50, df = 7, p < .05 respectively) (Figure 7d,e).
