[Retracted] Second-Generation Histamine H1 Receptor Antagonists Suppress Delayed Rectifier K⁺-Channel Currents in Murine Thymocytes

Figure 5

Electron microscopic images of thymocytes after incubation in azelastine or terfenadine. Thin-section electron micrographs of thymocyte membrane surface after incubating the cells in the external solutions containing no drug (a), 100 μM azelastine (b) or 10 μM terfenadine (c). Low-power (A) and high-power (B) views. (d) Diameters of thymocytes incubated in each solution were measured and averaged. (e) Endocytosis was quantified in thymocytes incubated in each solution by counting the numbers of small vesicles in the cytoplasm (arrows) and indentations (arrow heads) on the membrane surface per cells. Values are means ± SEM (n = 20). Differences were analyzed by ANOVA followed by Dunnett’s or Student’s test.
