Rats at 11 weeks of age were subcutaneously injected in both foodpads with 0.2ml of antigen-adjuvant emulsion for the induction of EAM. A peak increase in Bmax values of cardiac muscles of EAM was observed at day 18 (active phase), followed by a tendency to decrease until day 214 after immunization. However, there were no changes in Kd values at any stage of EAM. Thus, the present study indicates that β-AR densities change according to the stages of EAM.}, pages = {51--54}, title = {Alterations in Cardiac β-Adrenoceptors During the Development of Rat Experimental Autoimmune Myocarditis}, volume = {48}, year = {2000} }
