Electroacupuncture Alleviates Inflammation of Dry Eye Diseases by Regulating the α7nAChR/NF-κB Signaling Pathway

Figure 3

Effect of the electroacupuncture treatment on the tear flow and the lacrimal glands in the DED induced by scopolamine hydrobromide: (a) tear fluid flow (); (b) histopathological images of the cornea (hematoxylin-eosin staining, ×20) on day 35 (); (c) lacrimal glands under transmission electron microscopy; (d) the percentage of lacrimal gland area/total area (%). Quantitative data are expressed as . , , and vs. the Con group; ^# and ^## vs. the Scop group; ^& and ^&& vs. the Scop+Sham group. (c) Ultrastructural analysis under transmission electron microscopy revealed that EA decreased lipid droplet accumulation in LG acinar cell. Lipid droplets (black arrows).
