Effect of curcumin on expressions of NF-kBp65, TNF-a and IL-8 in placental tissue of premature birth of infected mice
Journal Title: Asian Pacific Journal of Tropical Medicine - Year 2017, Vol 10, Issue 2
Abstract
Objective: To observe the effect of curcumin on expressions of nuclear transcription factor-kappa Bp65 (NF-kBp65), TNF-a and IL-8 in placental tissue of premature birth of infected mice induced by lipopolysaccharide (LPS). Methods: A total of 60 C57BL/6 mice pregnant with 15 d 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 100 mg/kg of vitamin C through abdominal cavity injection and mice of treatment group and preventative group were given curcumin of 100 mg/kg through abdominal cavity injection after modeling operation and before 1 d of modeling operation, respectively.Atotal of 5mice of four groups respectively were executed by cervical dislocation after 6 h, 12 h and 24 h after constructingmodel. Placental tissues were collected and the immunohistochemical method SABC of immunologic tissue was used to detect the expression of NF-kBp65, TNF-a and IL-8 and peripheral blood of executed mice after 24 h was collected to detect the concentrations of IL-8, malondialdehyde (MDA) and superoxide dismutase (SOD), meanwhile live birth rate of four groups was contrasted. Results: Staining intensity of NF-kBp65, TNF-a and IL-8 in placental tissue of treatment group and preventative group was significantly higher than control group but lower thanmodel group (P< 0.05). Level of serumIL-8 andMDAof control groupwas 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). Conclusions: Curcumin can effectively prevent the active pathway of NF-kB in pregnant tissue of premature birth of infected mice, reduce the expression of TNF-a 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.
