It is shown that the model exhibits bifurcation and chaos patterns for a certain range of parametric values. This helps us to explain clinical observations and characterize different dynamic behaviors of the self-regulative system. © 1991.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyMathematicsArticleSCOPUS10.1016/0303-2647(91)90042-J
