The effect of continuous Jue tone intervention on blood pressure and vasoactive substances in hypertensive rats with a liver-fire hyperactivity pattern

Abstract

Jue tone is a kind of sound, using 3-mi as the main tone, and is melodious, profound, makes people feel comfortable and pleasant. This study aimed to explore the probable mechanism of Jue tone to reduce blood pressure (BP) in hypertensive rats with a liver-fire hyperactivity pattern by observing changes in BP as well as physiochemical indexes in plasma. Sixteen male spontaneous hypertensive rats (SHR) with a liver-fire hyperactivity pattern were randomly divided into a control group and a Jue tone group. The rats in the Jue tone group were treated with Jue tone (55–65 dB, played by the five elements of music rhythm instrument, a kind of physiotherapy regimen music played by Shen Wu) once a day for 4 weeks. The BP levels in each group were measured twice a week, on Monday and Friday. The levels of angiotensin II (Ang- II), thromboxane B2 (TXB2), endothelin-1 (ET-1), calcitonin gene-related peptide (cGRP), norepinephrine (NE), cortisol (CORT), and 5-hydroxytryptamine (5-HT). in plasma were detected by enzyme-linked immunosorbent assay after 4 weeks of intervention. BP and the levels of TXB2 and ET-1 in the plasma of the treatment group were significantly lower than those of the control group, while the level of cGRP was significantly higher. Jue tone can reduce the BP of hypertensive rats with a liver-fire hyperactivity pattern. The mechanism may correlate with a reduction in TXB2 and ET-1 and an increase in cGRP with the reduction of reactive oxygen species (ROS).
