Fig. 5. Intestinal barrier, liver, and kidney function. Data represent the mean ± SD of eight observations (n = 8/group). (A ) Plasma D-lactic acid, (B ) alanine aminotransferase, (C ) aspartate aminotransferase, (D ) total bilirubin, (E ) blood urea nitrogen, and (F ) serum creatinine are shown. *P < 0.05, **P < 0.01, comparison of different temperatures at the same pressure; ++P < 0.01 comparison of different pressures at the same temperature. ALT = alanine aminotransferase; AST = aspartate aminotransferase; BUN = blood urea nitrogen; T-bil = total bilirubin; Scr = serum creatinine.
