Anti-convulsant Activity of Goat Horn and Its Effect on Neurotransmitters in Mouse Brain
To investigate the anti-convulsant activity of goat horn and its effect on the main neurotransmitters in the brain of model mice.
Method
2
A total of 120 mice were randomly divided into a blank group,a model group,a positive drug group (estazolam, 1 mg·kg
-1
), a Saigae Tataricae Cornu (STC, 0.2 g·kg
-1
) group, and low- (1.25 g·kg
-1
) and high-dose (2.5 g·kg
-1
) goat horn groups. Drugs were administered by gavage once at 10 mL·kg
-1
. Those in the blank group and the model group were given the same volume of 0.2% sodium carboxymethyl cellulose (CMC-Na). The mice underwent threshold electrical stimulation once 2 h after administration. Ankylosing convulsion in the hind limbs of mice was used as the index to calculate the recovery period, convulsion rate, and mortality of ankylosing convulsion. Ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established to analyze the changes in the content of the main neurotransmitters in the brain tissues of mice.
Result
2
Two hours after intragastric administration of goat horn powder to mice, the recovery period of convulsion could be shortened and the convulsion rate and mortality were reduced (
P
<
0.05). In terms of anti-convulsant effect, the groups were ranked as follows: high-dose goat horn group
>
STC group
>
low-dose goat horn group. UPLC-MS/MS analysis showed that compared with the results in the model group, goat horn powder and STC decreased the content of glutamic acid and aspartic acid (
P
<
0.05) and increased the content of glycine,
γ
-aminobutyric acid, and 5-hydroxytryptamine (
P
<
0.05).
Conclusion
2
The results showed that goat horn had a significant anti-convulsant effect on the electroshock-induced convulsion mouse model, and the underlying mechanism was presumably attributed to the improvement of the development of convulsion by regulating the changes in neurotransmitter content in brain tissues.
