Conclusion
YJSB protect against LPS-induced intestinal barrier dysfunction anti-inflammatory and anti-apoptosis, suggesting its therapeutic potential against intestinal barrier injury-related diseases.
Methods
C57BL/6 mice and rat intestinal epithelial cells were treated with LPS. Thiazolyl Blue Tetrazolium Bromide assay were used to detect cell viability. D-Lactate, diamine oxidase and myeloperoxidase and cytokines were determined by enzyme-linked immunosorbent assay. Western blot was used to detect apoptosis-related proteins and tight junction (TJ) proteins. Real-time quantitative polymerase chain reaction was used to quantify the levels of mRNA expression of cytokines. Histological analysis was performed by hematoxylin and eosin staining. An immunofluorescence staining assay was performed to determine the expression level of TJ protein.
Objective
To investigate the protective effect of Yajieshaba (YJSB) on the intestinal barrier dysfunction induced by lipopolysaccharide (LPS).
Results
YJSB increased cell viability and decreased apoptosis, maintained intestinal permeability after LPS-induced. YJSB inhibited LPS-induced decrease of TJ protein expression, pro-inflammatory cytokine levels and neutrophil infiltration.
