The effect of Qing Huan Ling combined risperidone on the open field behavior of schizophrenic mice model

Abstract

ObjectiveTo observe the effect of Qing Huan Ling and (or) risperidone on locomotor activity and explorative behavior of schizophrenia mice model by open field test.MethodsSeventy kunming mice were randomly divided into 5 groups, one group as blank group. The rest groups ip MK-801 continuously 14 day, then randomly numbered: model group, risperidone group, Qing Huan Ling group and risperidone combined Qing Huan Ling group. Ig give corresponding drugs for each group 4 weeks, observe the change of locomotor activity and explorative behavior by open field test.ResultsAfter Ig 4 weeks, compared with the blank group, there were no obvious difference in locomotor activity and explorative behavior between risperidone group, Qing Huan Ling group and the combined group. Compared with the model group, risperidone had statistics meaning in the repression of explorative behavior (P < 0.05),the combined group has statistics meaning in the repression of locomotor activity and explorative behavior (78.92 ± 36.18 m vs. 186.92 ± 41.08 m, P < 0.01).ConclusionQing Huan Ling regulate the central nervous system of schizophrenia mice model; when combined with risperidone, it restrain the central nervous system of schizophrenia mice model and the effect is stronger than risperidone alone.Disclosure of interestThe authors have not supplied their declaration of competing interest.
