This study was carried out to investigate the effect of immobilization stress and electro acupuncture on the change of oxytocin (OT) immunoreactive cells in the hypothalamus of the male SD rats. Nine healthy and normal rats were divided into three groups, 3 SD rat in each group. The one group has been stimulated by electro acupuncture (EA, 2Hz) for 30 min and the other group by EA for 90 min and fixed group has not been stimulated.
The results were summarized as follows. In immobilized SD rats (n=3), OT immunoreactive cells were found in the Paraventricular nucleus (PVN). The number of OT immunoreactive cells of PVN were significantly increased after 30 min as compared with control group (p<0.05) and were also significantly increased after 90 min than 30 min(p<0.05). The present results demonstrate that immobilization stress and needle electrode electrical stimulation are effective III the modulation of expression of OT in the PVN area under stress conditions.
