丙二醇與HS 15對對乙酰氨基酚致肝損傷模型的影響
[Abstract]:Aim: to investigate the effects of propanediol (PG) and HS 15 on the liver injury induced by paracetamol (APAP) in mice. Methods: the model of liver injury was established by intraperitoneal injection of 300mg kg~ (-1) APAP in mice. The levels of plasma alanine aminotransferase, glutamic oxaloacetic transaminase and glutathione in liver homogenate were measured. The effects of PG (40% v / v) and HS 15 on liver injury induced by APAP were analyzed and compared. The inhibitory effects of PG and HS 15 on CYP2E1 were investigated by mouse liver microsomal incubation in vitro. Results: PG pretreatment for 7 days could attenuate the liver injury induced by APAP, but HS15 had no effect on the construction of APAP induced liver injury model. The results of Western blot showed that the expression of CYP2E1 protein in PG pretreatment group was significantly different from that in model group (P0.01), but there was no significant difference in HS 15 group. In vitro enzyme incubation experiment showed that 1% (v / v) PG could inhibit CYP2E1 obviously (P0.01). Conclusion: PG can interfere with APAP liver injury and is not suitable for use as a solvent for APAP and related liver protection drugs. The mechanism is related to the inhibition of CYP2E1 enzyme activity by PG, and HS 15 has no obvious effect on this model, and can be used as a solvent for the study of APAP liver injury.
