Abstract: Objective　To observe the changes of the concentration of Ca2+, contents of cAMP, CaM and activity of Ca2+/CaM-PK II in pheochromocytoma PC12 cells after combined soman and hypoxia injury. Methods　The changes of ［Ca2+］, and activity of CaM, cAMP and Ca2+/CaM-PK II in PC12 cells were studied after combined soman and hypoxia injury with radioimmunoassay. Results　The changes of ［Ca2+］, the contents of CaM, cAMP were significantly higher in hypoxic and soman intoxicated group than in soman intoxicated group and control group under hypoxia; but the activity of Ca2+/CaM-PK Ⅱ were significantly decreased. Conclusion　［Ca2+］, CaM, cAMP and Ca2+/CaM-PK Ⅱ exert important role in the damage of PC12 after combined soman and hypoxia injury.
