Fig. 4From: Detection and measurement of alpha-amylase in canine saliva and changes after an experimentally induced sympathetic activationSalivary alpha-amylase (sAA) activity (a) and heart rate (b) during an experimental model of sympathetic activation in dogs. TB: basal time; T-0: just starting the ejaculation; T + 0: just after ejaculation; T + 30: 30 min later. The plots show medians (line within box), 25th and 75th percentiles (boxes), min and max values (whiskers) and individual values (points). Asterisk indicates statistically significant difference (**P < 0.01) between timesBack to article page
