ABSTRACT

OBJECTIVE To explore the role of P38MAPK inhibitor on the soft palate reconstruction of the rats with chronic intermittent hypoxia. METHODS The animals were divided into normal control group, hypoxia control group and SB203580+hypoxia group (every group 20 rats). After 5 weeks, the expressions of p38MAPK and p-p38MAPK protein on the soft palate of the rats were detected with immunohistochemical techniques and western blot. RESULTS Compared with the normal control group, the soft palate tissue thickness of the hypoxia group were increased most obviously; Levels of p38MAPK were increased in hypoxia control group; Compared with the hypoxia control group, the levels of p-p38MAPK group were decreased in SB203580+hypoxia group. CONCLUSION p38MAPK may play important roles in the soft palate reconstruction of the rats with chronic intermittent hypoxia.
