The original article Ethanolic Extract of Marsdenia condurango Ameliorates Benzo[a]pyrene-induced Lung Cancer of Rats (J Pharmacopuncture 2014;17(2):7-17, DOI: http://dx.doi.org/10.3831/KPI.2014.17.011) by Sourav Sikdar, Avinaba Mukherjee, and, Anisur Rahman Khuda-Bukhsh, was published with an incorrect method in abstract due to a production error. The correct method in abstract are reported below. Methods: After one month of scheduled BaP feeding (50 mg/kg body-weight), lung cancer developed after four months. BaP-intoxicated rats were then treated with Condurango (0.06 mL) twice daily starting at the end of the four months for an additional one, two and three months, respectively. Effects of Condurango were evaluated by analyzing lung histology, reactive oxygen species (ROS) and antioxidant biomarkers, DNA-fragmentation, RT-PCR (Reverese Transcriptase- Polymerase Chain Reaction), ELISA (Enzyme linked immunosorbent assay) and western blot of several apoptotic signalling markers and comparing the results against those obtained for controls. We apologize to the authors and readers.
