A master's thesis in the College of Science, University of Basra (assesses the combined toxic effect of Newcastle disease viruses and camphor oil in the direction of cancer cells in the laboratory) and the researcher (Sanaa Abdul Hamid Ghaly) thesis demonstrated the ability of using a mixture of Newcastle disease viruses, and camphor oil to fight human breast cancer cells. The study measured cytotoxicity, detection of programmed cell death, and estimation of apoptotic proteins caspase 9, 8, and 3. The study concluded that the viruses of Newcastle disease and camphor oil had the most recent inhibition in the generation of the cell line of breast cancer type AMJ13, as well as induce the process of programmed cell death in in-dependent pathways to activate caspase. The study recommended a study. The synergistic effect of camphor oil with other viruses and its experiment on other types of cancer cells in the laboratory and the use of other techniques to study the synergistic effect, such as the immunological study and the experiment of using a mixture of virus and oil on laboratory animals
