Abstract:
BACKGROUND:There is a close relationship between epilepsy and apoptosis. The appearance of epilepsy can lead to the loss of neurons in the hippocampus, triggering a series of programmed cel death. OBJECTIVE:To investigate the effect of bone marrow stromal stem cel transplantation on apoptosis in epilepsy. METHODS:After modeled to be of epilepsy 45, Sprague-Dawley model rats were randomly divided into three groups, fol owed by given no intervention (moldel group), normal saline (normal saline group) or bone marrow stromal stem cel transplantation (transplantation group). At 1, 2 and 4 weeks after modeling, the number of Bax-positive cel s, Bcl-2-positive cel s and Bax/Bcl-2 were detected by immunohistochemistry. RESULTS AND CONCLUSION:The number of Bax-positive cel s, Bcl-2-positive cel s and Bax/Bcl-2 presented no obvious changes in the normal saline group at different time points. However, the number of Bax-positive cel s and Bax/Bcl-2 in the transplantation group was significantly decreased, while the number of Bcl-2-positive cel s significantly increased compared with the other two groups at 1, 2 and 4 weeks after modeling (P<0.05). Moreover, the above indicators varied significantly in the transplantation group at different time points after modeling (P<0.05). These results show that bone marrow stromal stem cel transplantation can affect the apoptosis and effectively reduce the apoptosis in rats with epilepsy by up-regulating the number of Bax-positive cel s and down-regulating the number of Bcl-2-positive cel s.
