Only the proband carrying all 3 mutations displayed the ERS/BrS phenotype, whereas one nor two mutations alone did not produce the clinical phenotype. Our results suggest a polygenic cause of the BrS/ERS arrhythmic phenotype due to mutations in these three gene variants caused a very significant loss of function of INa and ICa and gain of function of Ito. Various chemical agents have been used as an adjuvant treatment for giant cell tumor (GCT). However, the comparative effect of these chemicals remains unclear. Multinucleated and spindle cells from cultured GCT patients, characterized by Nanog and Oct4 expression with RT-PCR, were directly administered, in vitro, with concentrations of 1%, 3%, and 5% of H O and 75%, 85%, and 95% of ethanol for 10 minutes and concentrations of 0.003%, 0.005%, 0.01%, 0.03%, 0.1%, and 0.3% of H O for 5 minutes and were incubated for 24 hours. Cell morphology, cell viability, and flow cytometry after various concentrations of H O and ethanol exposure were assessed. H O in all concentrations caused loss of cell viability. The number of viable cells after H O exposure was related to the concentration-dependent effect. The initial viable spindle-shaped cell, multinucleated giant cell, and round-epithelioid cell had morphological changes into fragmented nonviable cells after exposure to H O . Flow cytometry using Annexin V showed cell death due to necrosis, with the highest concentration amounting to 0.3%. Administering local chemical adjuvants of H O in vitro caused loss of viable GCT cells. The number of viable cells after H O exposure was related to the concentration-dependent effect, whereas reducing concentration of H O may cause loss of viability and morphology of cultured GCT cells with the apoptotic mechanism. Administering local chemical adjuvants of H2O2 in
