Figure 2: VNS alleviates skeletal muscle injury. (a) Control group: normal skeletal muscle cell shape and arrangement; I/R group: skeletal muscle cell degeneration and necrosis, wide range of inflammatory cell accumulation; I/R+VNS group: mixed normal and pathological skeletal muscle cells, little inflammatory cell infiltration. (b) The muscle injury area in the three groups. (c) The serum concentration of CK and LDH. vs. control group; vs. I/R group; HPF: high-power field; CK: creatine kinase; LDH: lactic dehydrogenase.
