ABSTRACT
Objective To explore the relationship between tumor necrosis factor-?(TNF-?)level in the serum of maternal women with intrauterine infection of Toxoplasma gondii and absortion.Methods An examination was carried out on TNF-? in maternal sera and DNA of Toxoplasma gondii in the cervical secretions,and the aborted tissues of the abortion group,and the cervical secretions of the control group by ELISA and PCR,respectively.Results The TNF-? levels increased in the sera of women with intrauterine infection of Toxoplasma before abortion as compared with those of the control group and those of themselves after abortions.There were high TNF-? levels in the sera of prognostication abortion women with Toxoplasma infection before the anti-Toxoplasma treatment as compared with those of the control group and those of themselves after the treatment with azithromycin.Conclusion The results suggest that Toxoplasma gondii infection is an important factor to increase the TNF-? level in maternal serum.
