【Abstract】 To discuss step down mechanism of analogue otopuncture transformer, effect of analogue otopuncture transformer on change of blood pressure in irritable hypertension rats due to bounding was observed. After one week,blood pressure in rats of control group climbed and kept relative high level in th second and third week. While, blood pressure in rats of analogue otopuncture transformer group had lower than that in control group. There was a significant difference in comparison to control group during the second and the third week. It concluds that analogue otopuncture transformer has better hypotensive function resulting from its producing biological electrical imformation which regulate and control the vascular motor center.更多还原
