doi: 10.1016/j.heliyon.2023.e22641

Figure Lengend Snippet: Effects of ammonium pyrrolidine dithiocarbamate (PDTC) treatment on the expression of IL-1β, TNF-α, 3-NT, phosphodiesterase (PDE4), and cAMP in rats with immune-mediated liver injury. Rats were administered injections of BCG (125 mg/kg, i.v. on day 1) or BCG (125 mg/kg, i.v. on day 1) + PDTC (25, 50, or 100 mg/kg/d, i.p. on days 11, 12, and 13). (A, B) PDTC treatment decreases the levels of TNF-α and IL-1β in a dose-dependent manner ( P < 0.05). (C) The BCG-treated group shows an elevated expression of 3-NT; however, PDTC treatment inhibits its high expression in a dose-dependent manner ( P < 0.05). (D–E) In the BCG-treated group, the expression of PDE4 is significantly increased, whereas that of cAMP is significantly decreased in rat livers ( P < 0.05). PDTC treatment reverses the process in a dose-dependent manner ( P < 0.05). Data represent the mean ± S.D. of n = 10 rats. P -values above scatter charts indicate differences between groups. Comparisons between groups were performed using one-way ANOVA followed by Tukey's test.
