Effect of the electroacupuncture treatment on the tear flow and the lacrimal glands in the DED induced by scopolamine hydrobromide: (a) tear fluid flow (n = 6); (b) histopathological images of the cornea (hematoxylin-eosin staining, ×20) on day 35 (n = 3); (c) lacrimal glands under transmission electron microscopy; (d) the percentage of lacrimal gland area/total area (%). Quantitative data are expressed as mean ± SEM. ^∗P < 0.05, ^∗∗P < 0.01, and ^∗∗∗P < 0.001 vs. the Con group; ^#P < 0.05 and ^##P < 0.01 vs. the Scop group; ^&P < 0.05 and ^&&P < 0.01 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).
