The main objective is to systematically study the qualitative behavior of the model including existence of periodic solutions, global attractivity and oscillation. The main oscillation results are the results of the prevalence of the mature cells about the periodic solutions and the global attractivity results are the conditions for nonexistence of dynamical diseases on the populationeninfo:eu-repo/semantics/closedAccessImpulseDelayExistenceGlobal AttractivityOscillationPopulation DynamicsArticle841029103910.1016/j.nonwa.2006.06.001
