串珠素在大鼠牙髓損傷修復過程中表達變化的實驗研究
[Abstract]:Objective: to investigate the expression and possible role of series beads in the process of pulp injury and repair. Methods: 48 male SD rats were randomly divided into 4 groups (n = 12). The pulp injury model of one maxillary first molar was established in rats, and the other side of the same name was used as the normal control group. Immunohistochemical staining and Real-time PCR were used to observe the changes of the expression of series globin in the pulp tissue of each group, and the differences between the groups were compared by univariate analysis of variance (ANOVA). Results: immunohistochemical staining showed that the intensity of string bead staining in pulp tissue increased after pulp injury, and the average optical density of each experimental group was significantly higher than that of normal control group (P0.05). Compared with the normal control group, the relative expression of mRNA decreased significantly at 1 day after pulp injury, and then gradually increased with time, and increased significantly at 7 days after injury, but still significantly lower than that in the control group (P0.05). Conclusion: series beads may play an important role in the defense mechanism of pulp injury, but the increase of its expression is not caused by the increase of biosynthesis.
