Abstract:
Objective To study the effect of periodontitis on rats with chronic bacterial prostatitis. Methods A total of 80 male rats were randomly divided into the 4 weeks group (n=40) and the 8 weeks group (n=40), and then the two groups were randomly divided into the normal control group (N=10), the periodontitis group (PE=10), the chronic bacterial prostatitis group (CBP=10), and the peri-odontitis+chronic bacterial prostatitis group (CBP+PE=10) respectively. The pathological changes, inflammation score, level of TNF-αand IL-1β, and indicators of periodontal of all rats were observed. Results In the 4 weeks group, the indicators of periodontal in PE group and CBP+PE group were higher than that in N group and CBP group (P<0. 05), but there was no significant difference between PE group and CBP+PE group as well as between the N group and the CBP group (P>0. 05). The pathological changes, inflammation score,TNF-αlevel ,IL-1 β level in CBP+PE group and CBP group were higher than that in N group and PE group (P<0. 05), while there was no sing-nificant difference between N group and PE group as well as between CBP+PE group and CBP group (P>0. 05). In the 8 weeks group, the indicators of periodontal in PE group and CBP+PE group were higher than that in N group and CBP group (P<0. 05), but there was no sig-nificant difference between PE group and CBP+PE group as well as between the N group and the CBP group (P>0. 05). The pathological changes, inflammation score, TNF-α level , IL-1 β level in CBP +PE group and CBP group were higher than that in N group and PE group (P<0. 05),while there was no singnificant difference between N group and PE group (P>0. 05). The pathological changes, inflam-mation score,TNF-α level ,IL-1 β level in CBP+PE group were higher than those in the CBP group (P<0. 05). Compared between 4 weeks group and 8 weeks group, there was no obvious difference in N group in terms of periodontal indexes. Periodontal indexes in 8 weeks PE group was higher than that in 4 weeks PE group (P<0. 05), but there was no significant difference prostate tissue pathology, inflamma-tion score,TNF-α level,IL-1βlevel (P>0. 05). Pathology, inflammation score,TNF-αlevel, IL-1βlevel in 8 weeks CBP group were low-er compared to 4 weeks CBP group (P<0. 05), and there was no significant difference between the indexes of periodontal (P>0. 05). Prostate tissue pathology, inflammation score, TNF-αlevel, IL-1βlevel in 8 weeks CBP+PE group were lower than that in 4 weeks CBP+PE group (P<0. 05), but indicators of periodontal in 8 weeks CBP+PE group were higher than 4 weeks CBP+PE group (P<0. 05). Conclusion Chronic bacterial prostatitis combined with periodontitis can inhibit self-healing tendency of chronic bacterial prostatitis of rats and keep rats in chronic inflammatory phase.
