Die Lateralität und Lateralitätsinstabilität in der Diagnostik und Therapie

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.

Ethnopharmacologic study of chinese rhubarb

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.     

Wirksamkeit der Akupunktur bei der Therapie von idiopathischen Schmeckstörungen: Eine randomisierte Placebo-kontrollierte Studie

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.     

Veränderungen der Herzratenvariabilität (HRV) während Low Level Lasernadelakupunktur: Placebokontrollierte Studie an 19 herzgesunden Probanden

Background

Experimental and clinical studies postulate a neurobiological mechanism of acupuncture by modulating central pain systems, neurohormones and -transmitters. It seems to be quite likely that the autonomic nervous system (ANS) plays an important mediating role in this neuromodulation.

Aim

In measuring heart rate variability (HRV), as a non-invasive approach to the ANS-function, the object of this study was to monitor probable acupuncture-induced changes of autonomic balance. The innovative technology of laser-needle acupuncture offers for the first time a stimulation method which fulfils the demands on a placebo-controlled acupuncture trial not requiring controversial sham acupuncture.

Method

19 healthy voluntary subjects underwent 3 treatments in randomized sequence, consisting of placebo-, 1-point- (PC 6) and simultaneous 3-point- (PC 6, LR 3, SI 3) laser-needle-stimulation over 20 minutes. Before, during and after placebo-/verum laser-needle acupuncture, HRV-data for normalized HF(high frequency)- and LF(low frequency)-Power (nHF, nLF) and their quotient nLF/nHF obtained by power spectrum analysis (FFT), were measured and analyzed statistically at 5 different time points (ANOVA repeated measures, p < 0,05).

Results

During both verum applications, the 1-point- (PC 6) as well as the simultaneous 3-point- (PC 6, LR 3, SI 3) laser-needle stimulation, significant changes of the ANS-activity were found in comparison to the placebo application. The most significant modification of HRV was an increase of nHF (p < 0,05 (PC 6), p < 0,0001 (PC 6, LR 3, SI 3)) as an expression of growing vagal activity during acupuncture.

Conclusion

Laser-needle acupuncture causes in 1-point-stimulation (PC 6) as well as in simultaneous 3-point-stimulation (PC 6, LR 3, SI 3) significant changes in HRV in comparison to placebo application. HRV-monitoring seems to be a suitable approach in exploration of acupuncture-induced changes of ANS and could possibly be established in combination with laser needle acupuncture as a standard for further scientific and clinical acupuncture investigations which are greatly needed.
