ABSTRACT
Objective: To discovery the central mechanism of acupuncture Heart Meridian precondition myocardial ischemia in gene expression pattern, the authors applied gene chip tech to filter variably expressed genes in hypothalamus. Methods: Rats were seperated into normal, model, acupuncture Heart Meridian group and acup Lung Meridian group randomly. Acute myocardial ischemia rat model was made with ligation left anterior descending branch of the coronary artery. After model succeed, select hypothalamus seperately and mixed the same group together of 3 rats. Then applied Rats U230A genechip refered by Affymetrix Co. to compare the variations between these groups. Results: To compare with normal group, differential expression genes and expression sequence tags (ESTs) in model group were 73 with signal log ratio ≤ 1 and 92 with signal log ratio ≤-1 , mainly included ion channel, calcium/ calmodulin-dependent protein kinase Ⅱ inhibitor, antigen and so on. Similarly, compared with model group, differential expression genes and expression sequence tags (ESTs) were 190 with signal log ratio ≥ 1 and 34 with signal log ratio ≤-1 in acupuncture Heart Meridian group, mainly included 5-hydroxytryptamine receptor, cellular metabolism, fatty, immuno reaction, G-protein coupled receptors, ion transport, signal transductions and so on, while in acupucnture Lung Meridian, the number is 57 and 26 correspondly. Conclusion: There were exactly variations in hypothalamus mechanism that relate to acupuncture Heart and Lung Meridians.
ABSTRACT
Objective: The integrity of the corresponding dorsal root is important in the research of the effects of acupuncture Zusanli (ST 36) on gastric smooth muscle. Investigate the communicate channels of central control on the effect of acupuncture Zusanli (ST 36). Method: Selected 30 healthy adult SD rats and using veniua-glacial acid to made gastric mucosa ulcer model. Divided them into three groups, model group, cutting L1-S1group and transecting T10-T11group after the models have been made successfully, each group 10 rats. Implanted diameter in 0.2 mm Platinum Circle electrode into subserous of the ulcer place and recorded the myoelectricity activity of gastric smooth muscle before and after acupuncture Zusanli (ST 36). Acupuncture parameters, 2-100 Hz, lasting 20 mill. Results: Model group before acupuncture, (5.73±0.51) cycle per minitue (cpm), (2.28±0.57) mV; model group after acupuncture, (5.34±0.34) cpm, (1.06±0.13). Group that before cutting dorsal L4-S1, (5.65±0.26) cpm, (1.66±0.15) mV; group that after cutting dorsal L4-S1(5.40±0.23) cpm, (1.17±0.23), group that after cutting dorsal L4-S1and acupuncture, (5.26±0.18) cpm, (2.45±0.23). Group that before transecting dorsal T10-T11, (5.69±0.36) cpm, (1.91±0.25) mV, group that after transecting dorsal T10-T11, (4.98±0.53) cpm, (1.05±0.18) mV, group that after transecting dorsal T10-T11and acupuncture, (4.60±0.44) cpm, (2.52±0.38) mV. Conclusion: Acupunture Zusanli (ST 36) can inhibit the myoelectricity activity of gastric smooth muscle, cutting L4-S1 can strengthen the myoelectricity activity, but the effect of transect T10-T11 is better. So it can be said that the integrity of Dorsal root is important to the effect of acupuncture. The two-way regulation of Acupuncture has a close relationship with the higher centre above spinal cord.
ABSTRACT
This article gives a profound exploration on the theoretical origin, prohibitions and mechanisms of moxibustion for heat syndrome. Based upon the ancient and modem literature, this article also gives a classified summarization on diseases of moxibustion for heat syndrome, in order to obtain a thorough understanding about the theory and clinical application of moxibustion for heat syndrome, hence to further perfect the theory of moxibustion and guide the clinical practice.
