TABLE 8. Effect of TRH on locomotor activity and temperature after treatment with reserpine, chloral hydrate, chlorpromazine, diazepam, and phenobarbital.
Treatmenta | Dose | Motor Activity | Rectal Temperature |
---|---|---|---|
mg/kg | Counts/hr ± S.E.M | °C ± S.E.M. | |
Reserpine | 2.5 | 48 ± 27 | 33.3 ± 0.26 |
Reserpine + TRH | 2.5 + 30 | 1610 ± 290b | 38.3 ± 0.56b |
Chloral hydrate | 360.0 | 33 ± 8 | 31.4 ± 0.85 |
Chloral hydrate + TRH | 360.0 + 30 | 608 ± 74b | 33.1 ± 0.33 |
Chlorpromazine | 6.0 | 91 ± 29 | 34.0 ± 0.56 |
Chlorpromazine + TRH | 6.0 + 30 | 882 ± 96b | 38.4 ± 0.26b |
Diazepam | 12.5 | 80 ± 16 | 35.2 ± 0.37 |
Diazepam + TRH | 12.5 + 30 | 1131 ±479b | 37.3 ± 0.42c |
Phenobarbital | 95.0 | 294 ± 143 | 35.9 ± 0.25 |
Phenobarbital + TRH | 95.0 + 30 | 2634 ± 284b | 38.0 ± 0.22b |
All animals received 30 mg/kg of TRH after the various drugs. Details are described in “Methods.” Values in animals that did not receive TRH indicate base-line data after animals were injected with saline rather than TRH. Temperature was recorded in a separate group of mice 30 minutes after animals received TRH. Temperature in untreated control mice was 37.8 ± 0.19°C and with TRH was 38.5 ± 0.25°C (P < .01). Each value represents the mean ± S.E.M. of at least 10 mice.
P < .001 when compared with control.
P < .005 when compared with control.
