In the published article, there was an error in Figure 1 as published. In Figure 1D, there was a picture misuse of IHC staining MUC2 between group PGPH and group AH. The corrected Figure 1 and its caption appear below.
FIGURE 1
Synergistic effects of PD and PGP on ameliorating structural abnormality, excessive mucin secretion, and inflammatory state of the lung in CB rats. (A) Experimental design of 2% SO2-induced CB model and drug treatment. (B) Illustration of a combination of in situ intestinal perfusion and mesenteric lymphatic ligation. (C) Representative H&E-staining and AB-PAS staining images (C1) and MOD analyses (C2) of lung tissues after administration with low/medium/high dose of PGP (75, 150 and 300 mg/kg, groups PGPL/M/H), PD (2 mg/kg, group PD), PD + low/medium/high dose of PGP (groups PD-PGPL/M/H), and positive drug ambroxol hydrochloride (8.1 mg/kg, group AH), with the lung from groups NC and MC as a comparison. (D) Representative images (D1) and MOD analyses (D2 and D3) of IHC staining MUC2 and TNF-α expression in lung tissues after administration with PGP, PD, and PD-PGP, with the lung from groups NC and MC as a comparison [Original magnification ×200. Red arrow, acidic mucus. Data are expressed as mean ± SD, with data obtained from 10 randomly selected fields. Data are expressed as mean ± SD (n = 6); **p < 0.01 and ***p < 0.001 versus MC group; ###p < 0.001 versus NC group; &p < 0.05, &&p < 0.01 and &&&p < 0.001 versus PD group].
In the published article, there was an error in Figure 4 as published. In Figure 4A, picture duplication occurred in T-bet IHC staining analyses between group PGPL and group MC, group PD-PGPH and group NC, group PD and group PGPH/Lig, and GATA-3 staining analyses between group MC and group Sham. The corrected Figure 4 and its caption appear below.
FIGURE 4
Representative images (A1 and B1) and MOD analyses (A2 and B2) of IHC staining T-bet and GATA-3 expression in PPs (A) and lung tissues (B) of CB rats, after 90 min intestinal perfusion of PGP (groups PGPL/M/H), PD (group PD), and PD-PGP (groups PD-PGPH), with (group PGPH/Lig) or without mesenteric lymphatic vessel ligation. T-bet and GATA-3 expression in PPs and lung tissues from normal (groups NC), model (group MC), and sham operated (group Sham) rats were set as the comparison (Original magnification ×200. Data are expressed as mean ± SD, with data obtained from 10 randomly selected fields. Data are expressed as mean ± SD (n = 6); *p < 0.05, **p < 0.01 and ***p < 0.001 versus MC group; ###p < 0.001 versus NC group; &&&p < 0.001 versus PD group).
