Roup, # p 0.05 compared using the AT/L5P1).H E staining (Figure 7A) and quantification in the corneal epithelial thickness (Figure 7B) have been performed. The corneal epithelium of typical mice included 3 layers of cells using a thickness of 40.4 1.two . Within the DES group (0.1 BAC treated 1), the amount of layers was less, and the thickness was decreased to 16.3 1.2 , displaying a considerable distinction with manage a single (@ p 0.05). Soon after ten days of treatment, the corneal epithelial thickness of the AT group was 25.1 1.five , although the CsA and AT/L5P1-treated groups have been 31.five 1.1 and 34.2 0.six , respectively (Figure 7B), which have been considerably differentPharmaceutics 2021, 13,11 offrom the DES group ( p 0.05). Corneal epithelial thickness was not distinctive involving the AT/L5P1 and control groups.Figure 7.

(A) Hematoxylin and eosin (H E) staining of corneal sections in the eyes of mice in various groups (Scale bar = 75 ). (B) Quantification of corneal epithelial thickness. Information had been analyzed using one-way ANOVA and are expressed because the mean common deviation (SD); n = five, (@ p 0.05 compared using the handle group, p 0.05, compared with the DES group).Preceding studies have indicated that DES can lead to the loss of goblet cells [36,37]. Assessing the density or quantity of goblet cells is also an indicator for evaluating DES. The PAS staining final results showed that several goblet cells might be observed around the conjunctiva of mice inside the normal group, but a lot of had been lost within the DES group. Just after ten days of therapy, goblet cells had been not found within the AT group, but some goblet cells may be observed inside the tissue sections on the CsA, AT/L5, and AT/L5P1 groups (Figure 8).Pharmaceutics 2021, 13,12 ofFigure 8.

The arrows indicate the goblet cells.3.5.three. Quantification of Inflammatory Cytokines in Mouse Corneas The mouse corneas were extracted, and the variation in inflammatory cytokines was examined to evaluate the remedy efficacy of your many lutein/PVA mixtures (Figure 9). In the DES group, the concentration of inflammatory aspects including IL-1 (4.1 0.five pg/mL), IL-6 (22.7 8.two pg/mL), and TNF- (0.two 0.1 pg/mL) was significantly elevated, compared with all the normal group (@ p 0.05). The concentration of IL-1 (3.four 1.2 pg/mL) and IL-6 (21.5 3.7 pg/mL) was higher inside the AT group, as well, with no considerable distinction from the DES group. Inside the CsA group, the TNF- content (0.08 0.03 pg/mL) was drastically decreased ( p 0.05 compared with DES), while IL-1 (two.9 0.2 pg/mL) and IL-6 (16.6 2.9 pg/mL) showed no distinction from the DES group. Inside the AT/L5P1 group, the concentrations of IL-1 (1.8 0.two pg/mL), IL-6 (11.7 1.7 pg/mL), and TNF- (0.07 0.02 pg/mL) have been substantially decrease compared to these within the DES group ( p 0.05). Depending on these benefits, the AT answer mixed with 5 lutein and 1 PVA (AT/L5P1) proficiently inhibited inflammation in BAC-induced DES in mice.Pharmaceutics 2021, 13,13 ofFigure 9.
