Effect of NBI 27914 and non-selective CRF receptor antagonists on the latency of CRF-induced seizures
Receptor blocker | Dose (mg/kg) | Group size (n) | Latency of seizures (min) |
---|---|---|---|
None | 23 | 9.96 ± 1.10 | |
NBI 27914 | 0.33 | 7 | 2 = no seizures |
5 = 29.40 ± 3.53 * | |||
0.67 | 8 | 5 = no seizures | |
3 = 30.67 ± 3.33 * | |||
1.0 | 3 | 2 = no seizures | |
1 = 59 min latency | |||
α-Helical CRF9–41 | 0.5 | 12 | 4 = no seizures |
8= 21.4 ± 4.4 * | |||
d-Phe-CRF12–41 | 0.25 | 11 | 1 = no seizures |
10= 41.3 ± 11.8 * |
Animals received the indicated CRF antagonist or vehicle 15–20 min prior to the infusion of 0.15 nmol of CRF, via an i.c.v. cannula. Latency and duration of seizures were scored as described in the text.
Statistically different from control (P < 0.001, two-tailed Mann–Whitney U- test).
