Figure 2. Effects of the cyclic guanosine monophosphate analogue 8pCPTcGMP (1–100) on the active lymph pump in rat thoracic duct at different transmural pressures (inlet and outlet pressures set equally).

*Significant differences (P < 0.05) between active lymph parameters at control and after 8pCPTcGMP within each level of transmural pressure; ◊ indicates significant differences (P < 0.05) between control and ODQ treatment at 1 μm and 100 μm within each level of transmural pressure. 8pCPTcGMP, 8-(4-Chlorophenylthio)-guanosine 3′,5′-cyclic monophosphate sodium salt; ODQ, 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one.
