RESUMO
Objective To discuss different effects of low frequency sound waves of different timbres on microcirculation and transcutaneous oxygen partial pressure of Weizhong (BL40) of healthy people;To study the mechanism of somatosensory music therapy. Methods The same frequency (98.00 Hz), different timbres (sounds of guqin, flute, ocarina, bell, and drum were simulated) low frequency sound waves were played near Weizhong acupoint of 30 healthy persons. Laser Doppler flowmetry was used to analyze microcirculation and the changes of transcutaneous oxygen pressure of meridian acupoints, when each timbre was played for 60, 120, 180, 240 and 300 s. Results Sound waves of bell, drum, and flute made point microcirculation and transcutaneous oxygen pressure gradually increase, and the influence of drum>bell>flute;timbre waves of ocarina and guqin made the point microcirculation and transcutaneous oxygen pressure decrease gradually decrease, and the decrease of ocarina was more significant than that of guqin. In the same time point, sound waves of bell made point microcirculation and transcutaneous oxygen pressure increase more than the other sound waves (P<0.01). Conclusion Low frequency sounds of different timbres belong to different properties of five elements. They have different components in frequency spectrum, and can create different effects on acupoints.
RESUMO
Objective To investigate the effects of low-frequency sound waves (16~160 Hz) of somatosensory music on healthy people’s microcirculation in kidney and bladder meridians;To discuss the collateral channels biophysical mechanisms in somatosensory music treatment. Methods Low-frequency sound waves of somatosensory music were played near the 30 healthy people’s kidney and bladder meridians orderly. At the same time, Laser Doppler Flowmetry was used to analyze microcirculation in meridian acupoints.Results The low-frequency acoustic waves with different frequencies had significantly different effects on kidney and bladder meridians. The effects of the same frequency on different acupoints of the same meridian were similar. The G1 (49.00 Hz) showed the most significant effects on the kidney meridian (P<0.01);G2 (98.00 Hz) showed the most significant impact on bladder meridian (P<0.01).Conclusion The kidney and bladder meridians have selective absorption characteristics to the low-frequency sound waves of different frequencies. Specific frequency sound waves can cause resonance in kidney and bladder meridians.
RESUMO
Objective To observe the effect of Huahongjiangxiantang on hemorheology and plasma fibrinogen (FIB).Methods 100 patients with hypertension were randomly divided into two groups:the treatment group ( n=50) which were treated with Huahongjiangxian-tang,and the control group( n=50)were treated with Aspirin.Hemorheology and plasma fibrin were detected before and after treatment for 8 weeks.Results After 8 weeks treatment,there were significant depressions in whole blood viscosity(low shear rate),RBC deformability index and RBC aggregation index( P＜0.01 ),and better than the control group( P ＜0.05 ).There were significant changes in whole blood viscosity ( high shear rate),plasma viscosity,RBC rigidity index and plasma fibrin ( P ＜ 0.05 ).A number of indicators declined significantly in control group ( P ＜ 0.05 );The rate of platelet aggregation to improve the situation in the control group was better than that of the treatment group,but there was no statistical significance.Conclusion Huahongjiangxiantang can effectively reduce blood viscosity in patients with hypertension and improve the body's red blood cell function and fibrinolysis,benefit to the prevention and treatment of atherosclerosis and reduce the occurrence of thrombotic events.
