Effect of MCH on the loss of neurons of IAV-infected mice. (A) Representative Nissl staining in the hippocampal DG and CA1 regions and the cortex. Magnification: 100×, bar = 100 μm, MCH-L, MCH low dose + H7N7, MCH-H, MCH high dose + H7N7. (B) The number of neurons in the hippocampal DG and CA1 regions and the cortex. Data were expressed as mean ± SEM, n = 6, 5 slices for each mouse. *P < 0.05, **P < 0.01, ***P < 0.001
