Abstract:
OBJECTIVE:To observe the effects of Gegenqinlian colon positioning tablet(GGQLJC)on colon tissue PPAR-γ, NF-κB p65 protein expressions of model rabbits with damp-heat type ulcerative colitis(UC). METHODS:56 rabbits were random-ly divided into normal group(normal saline),model group(normal saline),sulfasalazine tablet(SASP)group(positive control, 0.300 g/kg),Gegenqinlian tablet (GGQL) group (0.225 g/kg) and GGQLJC high-dose,medium-dose,low-dose groups (1.036, 0.518,0.259 g/kg),8 in each group. Except for normal group,rabbits in other groups were cultured for damp-heat-type UC mod-el,intragastrically administrated in the second day of last administration,once a day,for 14 d. Disease activity index(DAI),co-lonic mucosal damage index (CMDI),histological damage (TDI) were scored;colon,spleen and thymus indexes were deter-mined;PPAR-γ,NF-κB p65 protein expressions in colon tissue were detected. RESULTS:Compared with normal group,DAI, CMDI,TDI scores and spleen index,colon index,NF-κB p65 protein level in colon tissue in model group were significantly in-creased(P<0.01);thymus index,PPAR-γprotein level in colon tissue were significantly reduced(P<0.01). Compared with mod-el group,above-mentioned indexes in each administration group were significantly improved (P<0.05 or P<0.01). Compared with GGQL group,DAI and TDI scores,spleen index,colon index,NF-κB p65 protein level in colon tissue in SASP group, GGQLJC high-dose,medium-dose groups were significantly decreased (P<0.05);PPAR-γ protein level in colon tissue in SASP group,GGQLJC high-dose,medium-dose groups were significantly increased (P<0.05 or P<0.01). CONCLUSIONS:GGQLJC has certain improvement effects on model rabbits with damp-heat type UC,which is superior to GGQL. The mechanism may be re-lated to increasing PPAR-γprotein level and decreasing NF-κB p65 protein level in colon tissue.
