ABSTRACT
OBJECTIVE To observe the ultra-structure and mucociliary transport speed of maxillary sinus mucosa of experimental rhinogenic acute sinusitis in rabbits.METHODS Fifteen healthy adult male New Zealand white rabbits were divided into experimental group(10 rabbits) and blank control group(5 rabbits) randomly.For the experimental group,a piece of polyvinyl acetal absorbent sponge(Merocel?) in size of 3 mm?5 mm?25 mm was inserted into the right-side nasal cavity of each rabbit.The sponges were soaked with 1ml type Ⅲ streptococcus pneumoniae solution.Two weeks after insertion,the mucociliary transport speed was measured by India ink solution method.All rabbits were sacrificed to obtain the right-side maxillary sinus mucosa for ultrastructure observation through transmission electron microscope.RESULTS The mucociliary transport speed of experimental group was much lower than that of blank control group,and the difference was statistically significant(P
