Abstract:
Objective To investigate the effect of magnesium sulfate on NF-κB p65,inflammatory cyto-kines in brain and serum of preeclampsia model rats by magnesium sulfate. Methods The healthy SD rats were randomly divided into 4 groups,normal pregnancy group(n = 10),magnesium sulfate control group(n = 10), preeclampsia(PE)model group(n = 10)and magnesium sulfate intervention group(n = 10). Blood pressure, urinary protein,blood urea nitrogen and alanine aminotransferase levels were detected in rats in each group. RT-qP-CR and ELISA were used to detect the expression of IL-1β,TNF-αand IL-6 in the brain and serum. Western blot assay was used to detect the expression of the NF-κB p65 in brain. Results The level of proteinuria,blood urea nitrogen and blood pressure in PE model rats were significantly higher than those in the normal pregnancy group and those in the magnesium sulfate intervention group at 20 days of gestation(P<0.05). Results of RT-qPCR and ELISA assay showed that IL-1β,TNF-α and IL-6 level in magnesium sulfate intervention group were sig-nificantly lower than those in PE model group(P<0.05),but still higher than those in the normal pregnancy group (P < 0.05). Western blot result showed that NF-κB p65 in the magnesium sulfate intervention group was lower than that in the PE group(P<0.05),but still higher than that in the normal pregnancy group(P<0.05). Con-clusion The prevention and treatment preeclampsia mechanism of magnesium sulfate may inhibit inflammatory cyto-kines through NF-κB p65 pathway in the preeclampsia model rats.
