Abstract
In this study, we examined changes in immunoreactivities of calcium binding proteins, such as parvalbumin (PV), calbindin (CB), and calretinin (CR), in the rat basolateral amygdala (BLA) 14 days after myocardial infarction (MI). In the MI-operated group, numbers of PV and CB immunoreactive ((+)) neurons in the BLA were significantly reduced compared to those in the sham-operated group. However, numbers of CR(+) neurons were slightly, not significantly, reduced in the MI-operated group. These results indicate that MI may decrease the immunoreactivities of PV and CB, not CR, in the rat BLA.
