BACKGROUND/AIM: In this study, the liver sinusoidal endothelial cells (LSECs)-protective effects of beraprost sodium (BPS) were investigated using mice with monocrotaline (MCT)-induced sinusoidal obstruction syndrome (SOS).
MATERIALS AND METHODS: The mice were divided into BPS, placebo and control groups. They were killed 48 h after MCT administration, and blood samples and liver tissues were evaluated. Immunostaining was performed using anti-SE-1 and anti-CD42b antibodies, whereas plasminogen activator inhibitor (PAI-1) and endothelial nitric oxide synthase (eNOS) levels were evaluated using western blot or real-time RT-PCR.
RESULTS: On pathological examination, SOS-related findings were observed in zone 3 in the placebo group; however, these were significantly suppressed in the BPS group. SE-1 staining showed a consistent number of LSECs in the BPS group compared with that in the placebo group, while CD42b staining showed a significant decrease in the number of extravasated platelet aggregation (EPA) in the BPS group. PAI-1 expression was significantly lower in the BPS group than in the placebo group; however, eNOS expression was significantly higher in the BPS group than in the placebo group.
CONCLUSION: Prophylactic administration of BPS is useful for suppressing the development of SOS through the protective effects of LSEC.
