Periodic Acid-Schiff (PAS) staining of conjunctival tissues. a (i) Control (ii) dry eye (DE) (iii) Omega-3 (210 mg/kg) (iv) 100 mg/kg ethanol extract of Diospyros kaki (EEDK)-treated (v) 50 mg/kg EEDK-treated, and (vi) 25 mg/kg EEDK-treated mice in all six groups. b The number of goblet cells is presented as a mean ± standard error of the mean value (n = 6 mice per group, *p < 0.05, **p < 0.01, ***p < 0.001). Arrows indicate PAS-positive cells (Goblet cells), original magnification (400 ×), and scale bars (50 μm)
