In order to investigate the effects of Yangsymtang on the activities of central nervous system, we observed the effects on convulsions induced by pentylenetetrazole, strychnine and picrotoxin. The sedative those on spontaneous motor activity and by rota rod method, the those on sleeping time induced by barbiturate and the alleviative those on pain induced by acetic acid and hind limb pressure also were analyzed. The results were as follows: 1. The solid extracts of Yangsymtang showed no anticonvulsive effects on convulsions induced by pentylenetetrazole, strychnine and picrotoxin. 2. As to the sedative effects by rota rod method, th solid extracts of Yangsymtang were recognized as significance(P<0.01). 3. The sleeping time induced by thiopental sodium was not prolonged by the oral administration of the solid extracts of Yangsymtang. 4. The oral administration of Yangsymtang did not influenced the sleeping induced by pentobarbital sodium significantly. 5. As to the effects on spontaneous motor activity, the oral administration of Yangsymtang made spontaneous motor activity decrease significantly(P<0.05). 6. The oral administration of Yangsymtang was significant on pain induced by acetic acid(P<0.001). 7. As to alleviative effects on pain induced by hind limb pressure. The solid extracts of Yangsymtang were not significant.
