3，15－二乙酰苯甲酰乌头宁镇痛作用与中枢Ca^（2＋）的关系

Relationship between 3,15一Diacetylbenzoylaconine Induced Analgesia and CentraI Ca￣(2+)_a

采用小鼠热板法测痛，脑室注射ＣａＣｌ０．３ｕｍｏｌ及皮下注射维拉帕米５ｍｇ／ｋｇ的镇痛作用均无明显影响，脑室注射乙二醇双醚四乙酸（ＥＧＴＡ）５ｎｍｏｌ可增强ＤＡＢＡ的镇痛作用，结果揭示ＤＡＢＡ的镇痛作用可能与中枢无明显关系。

n the mouse hot plate test,it was shown that sc 3,15-diacetylbenzoylaconine(DABA)induced analgesia was not influenced significantly by icv CaCl2 0.3μmol and sc vera-pamil 5 mg/kg,that icv EGTA 5 nmol exhibited enhancement of DABA analgesia.These re-sults suggest that the analgesia mediated by DABA is not possibly related to the central
