Abstract

To observe the effect of electroacupuncture (EA) on the related hormones of the hypothalamus-pituitary-adrenal (HPA) axis in rats with cerebral ischemia-reperfusion injury (CI-RI). Ninety Wistar rats were randomly divided into normal control, sham-operation (sham), model, EA acupoint and EA non-acupoint groups. CI-RI model was established by using modified middle cerebral artery occlusion (MCAO) and reperfusion. These rats were further divided into 1 day (d), 3 d and 7 d subgroups, with 6 cases in each. EA (1 mA, 2 Hz/30 Hz) was applied to acupoint "Zusanli" (ST 36) and "Quchi" (LI 11), and non-acupoints (5 mm lateral to ST 36 and 5 mm apart from LI 11 on the radial side respectively) for 30 min, once daily for 1 d, 3 d and 7 d separately. Serum cortisole (CORT) content was assayed by enzyme linked immunosorbent assay (ELISA), and the expression of hypothalamic adrenocorticotropic releasing factor (CRF) mRNA and glucocorticoid receptor (GR) mRNA, and pituitary adrenocorticotrophic hormone (ACTH) mRNA was assayed by reverse transcription polymerase chain reaction (RT-PCR) method. Compared with normal and sham groups, serum CORT levels of model and EA non-acupoint groups on the 1st, 3rd and 7th day increased significantly (P < 0....Continue Reading
