Reduced normogastric electrical activity associated with emesis: A telemetric study in ferrets

Figure 2 Intra-abdominal pressure recordings. Intra-abdominal pressure was recorded via a telemetry transmitter in the abdominal cavity (C50-PTX, DSI^®), showing emetic episodes-each composed of several retches and one vomit-induced by apomorphine (0.25 mg/kg sc) (A) and cisplatin (10 mg/kg ip) (B). Both recordings were obtained from the same animal. C: Correlation between the number of retches + vomits (R+V) induced by cisplatin (10 mg/kg ip) and apomorphine (0.25 mg/kg sc), quantified by direct observation and from the intra-abdominal pressure traces. Results plotted as individual values, n = 16 (data obtained from 11 animals). Spearman correlation coefficient (r), the linear regression (plain line) and 95% confidence interval (dotted line) are indicated on the graph.
