| Popis | The aim of this study was to evaluate the amount of Endothelin 1 (ET 1) gene expression in the vasospastic vessel of the flap pedicle to prove or disprove the role of ET 1 gene expression in pathogenesis of mechanically induced vasospasm The vasospasm was induced by the tension on the pedicle of the pedicled caudal superficial epigastric flap on 8 pigs Laser Doppler was used for peripheral blood flow measurement Specimens from the vasospastic vessel (B) and from the flap border with no vasospasm (A) were taken 2 h after the stimulus initiation Detection of ET 1 mRNA by Quantitative Real Time RI PCR was performed beta actin was selected as an acceptable reference gene. Relative gene expressions and time indicators of vasospasm were compared in both groups. In conclusion the expression of the ET 1 gene in the mechanically induced vasospastic vessel of the pedicled flap was not significantly increased In this study the causality of the vasospasm pathogenesis and gene expression of ET 1 was not proven |
