Altered spontaneous contractions of the ileum by anesthetic agents in rats exposed to peritonitis

Figure 1 KCl (80 mmol/L) induced contractions of isolated ileum muscle segments in control and peritonitis groups. No statistical difference was observed between groups (P > 0.05).

Figure 2 Changes in the spontaneous contractions of the isolated ileum muscle segments. A: Amplitudes were calculated as a percentage of the contraction induced by KCl (80 mmol/L) from both control and peritonitis groups; B: Frequencies were expressed as the number of contractions for 10 min from both control and peritonitis groups. (^aP < 0.05 vs control group; analysis of variance followed by Newman-Keuls test).

Figure 3 Amplitudes of the contractions induced by anaesthetic agents. A: Control group; B: Peritonitis group; both were calculated as the percentage of the initial contractions. (^aP < 0.05 vs initial contractions, ^cP < 0.05 vs propofol and midazolam; analysis of variance followed by Newman-Keuls test).

Figure 4 Changes in the frequency of spontaneous contractions. A: Control group; B: Peritonitis group. Both were expressed as the number of contractions for 10 min. (^aP < 0.05 vs initial contractions; analysis of variance followed by Newman-Keuls test).
