15d-PGJ2 pretreatment group attenuate ConA-induced acute hepatitis. (a) The index of plasma ALT and AST levels at 6 h, 12 h, and 24 h after ConA injection in mice and effects of both low (10 μg) and high (25 μg) dose 15d-PGJ2 pretreatment groups at the same time. Data are expressed as mean ± SD (n = 6, *P < 0.05 for NC versus ConA, #
P < 0.05 for ConA versus ConA + 10 μg 15d-PGJ2, and +
P < 0.05 for ConA versus ConA + 25 μg 15d-PGJ2). (b) Hematoxylin and eosin staining of liver sections (NC or NC + 10 μg 15d-PGJ2 or NC + 25 μg 15d-PGJ2 or ConA or ConA + 10 μg 15d-PGJ2 or ConA + 25 μg 15d-PGJ2). The cellular necrotic or edematous areas were analyzed with Image-Pro Plus 6.0, indicating there existed statistical significance among different groups (n = 6, *P < 0.05 for NC versus ConA, #
P < 0.05 for ConA versus ConA + 10 μg 15d-PGJ2, +
P < 0.05 for ConA versus ConA + 25 μg 15d-PGJ2, black bar for 200 μM, wide arrow for necrotic area, and narrow arrow for edematous area).
