| Figure 4: The change of SP nerve fibers in tracheal smooth muscle at
different time after SS exposure during early postnatal periods. A: fluorescence
photomicrographs of SP nerve fibers in Tracheal Smooth Muscle (TSM) after FA
or at 1 days, 3 days and 7 days after SS exposure. B: changes of SP nerve fiber
density in tracheal smooth muscle after 10 days FA or at 1 day, 3 days and 7
days after 10 days SS exposure. Arrows: the localization of SP-immunoreactive
nerve fibers. Data are mean ± SE of 6 mice in each group. *P ≤ 0.05, significant difference between FA- and SS-exposed mice. Magnification: ×285. |
