Abstract:Objective To investigate the effects of Qi-BoostingToxin-Resolving Formulae (QBTRF) by regulating mitochondrionpathway in the developing process of nasopharyngeal carcinogenesisamong rats. Methods 72 SD rats were randomly divided into modelgroup, Qi-Boosting Toxin-Resolving Formulae (QBTRF) group, vitaminA acid group. All these animals were subcutaneously injected inaxillary fossa with N, N闭于切片机’-dinitrosopiperazine (DNP) and12-O-tetradecanoylphorbol (TPA) in combination with exhaustedswimming to establish the model of nasopharyngeal carcinomas. QBTRFwas given to intervention. Samples were fixed in 4% neutralparaformaldehyde for pathohistological evaluation,, and the protein expressionwere detected by SABC immunohistochemical and mRNA expression weredetected by RT-PCR. Result In the *** hyperplasia stage ofinduced cancerous transforming lesion in the nasopharyngealepithelia, no significant difference were determined in theexpressing activities of Bcl⑵, Bax, Cytochrome-C and Caspase⑶ inQBTRF group and vitamin A acid group (P闭于羊肉切片机维建>0.05), compared with themodel group respectively. At the pathological stage of atypicalhyperplasia, the expressing activity of Bcl⑵ was significantlylower (Pintervention<0.05) and the activities of Cytochrome-C and Caspase⑶were significantly higher in QBTRF group than that of model group(P<0.05). Though the expressing activity of Bax was higher in QBTRFgroup than that of model group, no significant difference wasdetermined between them (P木料切片机>0.05). There was a parallel tendency ofexpressing activity in either Bax mRNA or Bcl⑵ mRNA with Bax orBcl⑵ itself respectively in any stage of pathology.ConclusionThe anticancer effect of QBTRF wasrealized by regulating mitochondrion pathway in the developingprocess of carcinogenesis among rats.
