ET lethality in BALB/cJ mice. ET-treated female BALB/cJ mice at doses of 100 μg (n = 5), 50 μg (n = 10), 37.5 μg (n = 7), 25 μg (n = 6), and 10 μg (n = 6), were compared to animals treated with 100 μg of EF alone (control). All injections were intravenous in 100-μl volume. All differences in survival curves when compared against each other were statistically significant (P < 0.05) by the log-rank test except for the comparison between the 25 μg of ET dose and 100 μg of EF dose (P = 0.1573).
