Figure 6. Iberiotoxin attenuated phagocytotic activity recovered by unoprostone and M1. A, B: Unoprostone (1 µM), and M1 (1 µM) or iberiotoxin (1 µM) were added just before light irradiation. Latex beads were added just after light irradiation, and 4 h later, they were removed by washing. The number of latex beads was counted, and phagocytosis was expressed as the percentage of latex beads to total cell numbers. Data are expressed as mean±SEM (n=8). ** p<0.01 versus Unoprostone or M1 treatment; ^## p<0.01 versus vehicle (Student’s t-test). Con: control; Veh: vehicle; IbTX: iberiotoxin.
