Figure 1.
The relationship between the log-dose of resiniferatoxin (RTX) given subcutaneously to groups of Suncus and the mean±s.e.mean latency and number of emetic episodes induced over a 1-h observation period. The number of animals responding over the number tested is shown for each dose. For the dose of 1000 μg kg−1 the value for latency is calculated from the three animals with an early response (see text for details).
