| Abstract: | The activating effects of various inositol polyphosphates on Ca- dependent K channels of membrane in single internally and externally perfu- sed lacrimal acinar cells in mouse were studied using the whole cell current re- cording of patch elamp technique.It was proved that(1,4,5)triphosphate and(1,3,4,5)tetrakiphosphate have synergism to activate K channels.The specificities of various combinations of inositol polyphosphates were also com- pared. |
