The disturbance and instability of laterality are obstacles to diagnostics and therapy. Correction prior to starting therapy is required. They also predispose toward defined health problems and unspecific diseases. Numerous research activities provide evidence of the relevance of undisturbed laterality in diagnostics and therapy. Techniques of testing and therapeutic corrections will allow for optimized therapy success.  相似文献

Based on the principle of completeness, Qigong is described as a method uniting external and internal paths to insight, and this can be perceived while practicing it. The common principle which we approach in every Qigong exercise is named the Dao. In quantum physics, there are also phenomena showing an underlying unity: entanglement of atomic systems.  相似文献

This paper deals with an interdisciplinary study covering historic, botanical, phytochemical, pharmacological and clinical aspects of rhubarb and related species, to lay stress on the correlation between plant phylogeny, chemical constituents and purgative activity.

It was found that the official rhubarbs were exclusively restricted in the Sect. Palmata e.g. Rheum palmatum R. palmatum var. tanguticum R. officinale; the following criteria may serve as their standard, viz., the presence of sennoside derivatives and rhein, the occurrence of the reduced form of rhein and aloe-emodin, the leaves with any kind of palmate incision. Comprehensive multivariate analyses showed that there is a very close relationship between the leaf incision, existence of sennosides or rhein and purgative activity.  相似文献

Background

The German Acupuncture Trials (GERAC) have brought good results regarding the acupuncture treatment of lumbago and headache. However, for reasons of scientific practicability, patients included in these trials were restricted by certain criteria (among others, excluding patients after spinal surgery, past experiences with acupuncture, patients with ischialgia). Also, microsystems and other acupuncture-related techniques, such as moxibustion or cupping, were not included.

Objective

The objective of this treatment observation was the assessment of early as well as late results of acupuncture treatment series for lumbago and headache performed on the mixed patient collective of a general practitioner's practice.

Methods

The observation included all patients who received acupuncture for chronic back pain or headache. The treatment observation consists of data collected from 192 treatment series (10 acupuncture sessions each) for lumbago, and 86 treatment series (10 acupuncture sessions each) for headache. There were no restrictions regarding microsystems or acupuncture-related techniques. Acupuncture was administered according to the criteria of Traditional Chinese Medicine; there were no restrictions regarding the selection of the acupuncture points.

Results

The benefit of the treatment in the lumbago group was rated none or poor in 18 cases (9.4 %), moderate in 35 (18.2 %), and very good in 139 (72.4 %) cases. In the headache-group the benefit was rated none or poor in 2 cases (2.3 %), moderate in 28 (32.6 %), and very good in 56 (65.1 %) patients.

Conclusion

The results were encouraging: not only in the restricted setting of a large scientific study, but also within the mixed patient collective of a general practitioner's practice, acupuncture can lead to good results in the therapy of chronic back pain and headache.  相似文献

Background

At present, the state-of-the-art medication in treating idiopathic taste disorder (gustatory dysfunction) is zinc. If zinc medication was unsuccessful, not tolerated or if it is contraindicated the persons affected can hardly be helped.

Objectives

In a randomized placebo-controlled clinical trial an attempt was made to determine the efficacy of acupuncture.

Methods

The treatment group was treated with acupuncture needles, the placebo group with an inactive acupuncture-laser. Endpoints of the study were changes in the taste test, the quality of life and the severity of symptoms of depression (BDI) as well as mood changes (ZMS). Satisfaction with the success of the respective therapy was also evaluated. Data were collected before and after therapy and again for the treatment group 10 weeks after completion of the treatment period.

Findings

Treatment with real acupuncture showed a significant improvement in gustatory function as well as a significant improvement in psychological symptoms. Greater satisfaction with the treatment results was evident in the treatment group. The treatment results of acupuncture remained stable over a period of ten weeks after completion of the treatment.

Conclusion

Acupuncture was effective in the therapy of idiopathic taste disorders and therefore it is an effective alternative when zinc medication is not tolerated or unsuccessful. But it is also suitable as a therapy of first choice. Acupuncture can be considered as an extension of the therapeutic spectrum in the difficult treatment of taste disorders.  相似文献
