目前指纹图谱已成为国际公认的控制中药或天然药物质量的有效手段。近年来对中药指纹图谱进行了很多探索性研究,但是真正将指纹图谱作为质量标准的只有中药注射剂,而其他的中药指纹图谱研究多只停留在研究阶段。造成中药指纹图谱研究瓶颈的原因很多,如天然产物成分的复杂性,指纹图谱的分析结果中往往有大量的杂质峰群存在,而现有的分析手段很难使这些杂质峰群达到很好的分离,为此提出了构建“区间指纹图谱”。对“区间指纹图谱”构建程序、建立方法、构建模式、应用问题等进行了较全面地研究和分析,并以神安颗粒为例进行了分析。  相似文献

第四是在进行指纹图谱研究中重视谱效关系的研究。目前国家食品药品监督管理局提出了中药注射剂指纹图谱研究要求,各生产厂家也在积极地进行指纹图谱研究,已有一些品种制订了指纹图谱的标准。在目前中药成分与药效的关系尚不明确,导致不良反应的成分也不明确的情况下,不宜过度强调指纹图谱保持一致,可以通过对不同批次产品临床疗效与不良反应的调查,反过来研究不同批次间的差异,可能对研究药效成分及导致不良反应的成分更有帮助。建议生产厂家在进行指纹图谱研究时,还  相似文献

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

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

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

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.  相似文献
