    Abstract:
    OBJECTIVE: To detect the effects of antimicrobial agents on the toll-like receptor (TLR) and so on in liver tissue of rats after intragastric infusion with alcohol with vibrio vulnificus (VV) sepsis. METHODS: Sprague-Dawley rats were randomly divided into normal control group (N group, n = 6), rats after intragastric infusion with alcohol control group (group A, n = 6), drug intervention on rats after intragastric infusion with alcohol control group (group AA, n = 6), rats after intragastric infusion with alcohol with VV sepsis group (group AV, n = 24, killed at 2, 6, 12, 24 hours after injecting VV respectively, six rats per group), as well as drug intervention on rats after intragastric infusion with alcohol with vibrio vulnificus sepsis group (group AVA, n = 30, killed at 6, 12, 24 hours and one week after injecting VV respectively, six rats per group). The expressions and dynamic changes of TLR4 mRNA and so on by RT-PCR in liver tissue of each group were measured. RESULTS: The expressions of TLR4 mRNA in AV-6 hours group was 0.775 +/- 0.101, the expressions of TLR4 mRNA in AVA-6 hours group was 0.600 +/- 0.064; the expressions of TLR4 mRNA in AV-12 hours group was 0.918 +/- 0.133, the expressions of TLR4 mRNA in AVA-12 hours group was 0.583 +/- 0.112; the expressions of TLR4 mRNA in AV-24 hours group was 0.732 +/- 0.110, the expressions of TLR4 mRNA in AVA-24 hours group was 0.512 +/- 0.118. Compared with AV group, the expressions of TLR4 mRNA in liver diminished greatly in AVA group at 6, 12 and 24 hours after being injected with VV (AVA-6 hours group compare with AV-6 hours group, t = -3.573, P < 0.01; AVA-12 hours group compared with AV-12 hours group, t = - 4.722, P < 0.01; AVA-24 hours group compare with AV-24 hours group, t = - 3.340, P < 0.01). CONCLUSION: The treatment with antibacterial agents may reduced the expression of TLR and so on in liver of rats after intragastric infusion with alcohol with VV sepsis. The treatment with antibacterial agents may regulate the balance of the inflammatory response in VV sepsis and generate the visible therapeutical effect for VV sepsis.
