庆大霉素中毒性聋与肾阳虚证相关性初步实验研究

本研究通过对庆大霉素中毒性聋豚鼠模型的行为外观、壳温与核温、耗氧量、应激能力的观察，结果发现豚鼠表现为萎靡、蜷缩、活动迟缓、反应迟钝、体重及进食量下降、壳温及核温降低氧耗量降低、耐冻及冷水游离时间缩短等典型阳虚证候；本研究还运用补肾助阳药进行治疗，上述阳虚证侯得以纠正，并且提高了模型的听力水平。从“以药测证”的角度阐明庆霉素中毒性聋中医证候为肾阳虚证。     

阳虚动物牙周组织学变化和助阳药作用的研究

一般认为,肾与内分泌尤其与垂体肾上腺系统关系密切,临床肾阳虚证有下丘脑——垂体——肾上腺轴功能紊乱。在实验方面,大剂量皮质素可制造动物阳虚证,用助阳药进行防治确能抗衡其致病作用。鉴于牙周病病因与祖国医学肾虚学说以及现代医学中牙周病内因的肾上腺皮质功能障碍有密切关系,为此,我们采用大剂量醋酸氢化可的松制造动物阳虚证,同时观察牙周组织学变化,以及合用助阳药的影响,为探索牙周病中西医学理论及中药防治提供根据。     

天雄的历史源流考证

天雄药用历史悠久,早在《神农本草经》中即有收载,功专祛风散寒,益火助阳。该文在系统查阅古今文献基础上,针对历代本草文献对天雄基原的认识难以统一的问题,正本清源,从基原、炮制、功效3个方面考证辨析,并将古今演变情况进行对比。唐代以前,古人对天雄认识较为粗略,但认为天雄和附子有显著差异;唐宋时期,天雄多种植而得,出现将天雄和附子视为一物的观点;明清时期多沿用之前本草书籍记载,分歧延续,终未达成认识上的统一。历代文献记载的天雄来源主要有三:其一,天雄为川乌周围不生附子者;其二,天雄是种附子而生者,即个大的附子;其三,天雄为草乌生成者,即长三寸的草乌。而对于天雄的性状记载主要集中于旁不生子、形细而长等描述。近现代则普遍将个大附子视为天雄。古代天雄炮制方法较多,炮法在历代皆有沿用,随着其疗效及减毒作用方面的研究逐步深入,新增姜汁制、童便制、酒制等不同炮制方法,近现代天雄炮制方法几近失传,仅在岭南地区和四川保留有特色炮天雄工艺,两地工艺主要在最后一步存在差异。“天者健也,雄者壮也”足可见“天雄”之名将祛风散寒、益火助阳的功效展现得淋漓尽致,现代天雄应用则逐渐向补阳壮阳方面偏重。     

岭南炮天雄的炮制工艺优选

目的:优化并规范岭南炮天雄的炮制工艺,为提高该产品的生产效率及质量提供参考。方法:以炮天雄中3种单酯型生物碱(苯甲酰新乌头原碱、苯甲酰乌头原碱、苯甲酰次乌头原碱)和3种双酯型生物碱(新乌头碱、次乌头碱、乌头碱)质量分数为评价指标,在单因素试验基础上,通过正交试验考察浸漂时间、高压蒸制时间和砂炒温度对岭南炮天雄炮制工艺的影响。结果:最佳炮制工艺条件为浸漂时间5 d,高压蒸制时间1.5 h,砂炒温度210~230℃,姜汁比例8%。炮天雄的单、双酯型生物碱质量分数分别为0.120 5,0.031 1 mg·g-1。结论:优选的岭南炮天雄炮制工艺稳定可行,能进一步规范相关指标,提高生产效率和产品质量,为该药材的大规模生产提供参考。

参茸助阳丸治疗肾阳亏虚型勃起功能障碍的临床与实验研究

目的:观察参茸助阳丸治疗肾阳亏虚型功能性勃起功能障碍的临床疗效。方法:121例患者随机分为两组,分别用参茸助阳丸(60例)和五子衍宗丸(61例)治疗,8周后对相关指标进行观察。建立肾阳虚动物模型,分别给予大、中、小剂量参茸助阳丸、大剂量强肾片和蒸馏水,观察用药前后动物性器官指数、阴茎勃起潜伏期、单位时间内交配次数和低温条件下生存时间等指标变化。结果:参茸助阳丸组近期治愈7例,显效28例,有效20例,无效5例,总有效率91.67%,总有效率和对疲乏无力、畏寒肢冷2组症状的改善优于对照组,无毒副作用。参茸助阳丸能够提高去势大鼠阴茎对外部刺激的兴奋性,可缩短动物阴茎勃起潜伏期;与去势模型对照组相比较可提高精囊 前列腺、提肛肌脏器指数;可使大鼠交配能力明显增强,单位时间内完成的扑捉及射精次数增加。参茸助阳丸大剂量组能够明显延长阳虚证小鼠在8℃条件下低温游泳存活时间。结论:通过临床观察和动物实验,参茸助阳丸对肾阳亏虚型功能性勃起功能障碍有较好的疗效,可以改善机体的肾阳虚证候。

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.
