Figure 3
Histological study of the inflammation of the synovial tissue. A very mild inflammation in the ankle joint from the animals in the saline (a) and saline-EA (b) groups. Massive accumulation of inflammatory cells in the swollen joint (c) and an apparent periosteal edema (d) are seen in the FCA-injected group. (e) Less inflammation and hyperplastic synovial cells are presence in the ankle joint of the animals in the FCA-EA group. (f) A severe inflammation of the ankle joint is detected in the FCA-EA (nonacupoint) group. H&E staining; original magnification, 400x.
