Abstract
To observe the effect of curcumin on expressions of nuclear transcription factor-kappa Bp65 (NF-κBp65), TNF-α and IL-8 in placental tissue of premature birth of infected mice induced by lipopolysaccharide (LPS). A total of 60 C57BL/6 mice pregnant with 15d were collected and randomly divided into control group, model group, treatment group and preventative group. LPS was repeatedly injected in abdominal cavity to construct infected premature birth model, while mice of control group were given with 100mg/kg of vitamin C through abdominal cavity injection and mice of treatment group and preventative group were given curcumin of 100mg/kg through abdominal cavity injection after modeling operation and before 1d of modeling operation, respectively. A total of 5 mice of four groups respectively were executed by cervical dislocation after 6h, 12h and 24h after constructing model. Placental tissues were collected and the immunohistochemical method SABC of immunologic tissue was used to detect the expression of NF-κBp65, TNF-α and IL-8 and peripheral blood of executed mice after 24h was collected to detect the concentrations of IL-8, malondialdehyde (MDA) and superoxide dismutase (SOD), meanwhile live birth rate of four groups was contrasted. Staining intensity of NF-κBp65, TNF-α and IL-8 in placental tissue of treatment group and preventative group was significantly higher than control group but lower than model group (P<0.05). Level of serum IL-8 and MDA of control group was significantly lower than the other three groups (P<0.05) and level of blood of SOD in model group was significantly lower than control group (P<0.05). Levels of serum IL-8 and MDA of treatment group and preventative group were significantly lower than model group (P<0.05) while level of SOD was significantly higher than model group (P<0.05). Live birth rate of treatment group and preventative group was significantly higher than model group (P<0.05). Curcumin can effectively prevent the active pathway of NF-κB in pregnant tissue of premature birth of infected mice, reduce the expression of TNF-α and IL-8 and relieve the damage of lipid peroxide of oxidative stress of LPS on mother-fetus and further to achieve the objective of preventing and curing premature birth induced with infection.
