RESUMO
Objective To observe the changing rules of the voltage-current characteristics and blood flow perfusion of Sanyinjiao (SP6) at different time points of a menstrual cycle in healthy female subjects, and provide evidence for acupoint specificity.Method Fifty-one healthy college students were observed for the voltage-current characteristics and blood flow of Sanyinjiao and its control point before, during and after menstruation.Result The increasing volt-ampere area, decreasing volt-ampere area and inertial area of left Sanyinjiao were significantly smaller than those of the control point during and at the end of menstruation (P<0.05), and the inertial area of right Sanyinjiao was significantly smaller than that of the control point during menstruation (P<0.05); during non-menstruation period and at the end of menstruation, the blood flow perfusion of bilateral Sanyinjiao was significantly larger than that of the control point (P<0.05), and the blood flow of left Sanyinjiao was significantly larger than that of the control point (P<0.05) during menstruation period; the blood flow perfusion of right Sanyinjiao showed a significant negative correlation with the increasing volt-ampere area and inertial area (P<0.05).Conclusion Acupoint can sensitively reflect the qi-blood change of human body, and the rich blood flow in acupoint area should be a crucial reason causing the low resistance.
