[Retracted] α1-Adrenergic Receptor Blockade by Prazosin Synergistically Stabilizes Rat Peritoneal Mast Cells

Figure 4

Effects of β2-adrenergic receptor antagonist on adrenaline-induced inhibition of mast cell degranulation. (a) Differential-interference contrast (DIC) microscopic images were taken after exocytosis was externally induced by compound 48/80 in mast cells incubated in the external solutions containing no drug (A), 1 mM adrenaline (B), or 1 mM adrenaline in the presence of 1 mM butoxamine (C). (b) After exocytosis was induced in mast cells incubated in the external solutions containing no drug and 1 mM adrenaline with or without the presence of 1 mM butoxamine, the numbers of degranulating mast cells were expressed as percentages of the total mast cell numbers in selected bright fields. # vs. incubation in the external solution alone. Values are . Differences were analyzed by ANOVA followed by Dunnett’s test.
