BackgroundYamamoto New Scalp Acupuncture (YNSA) is a well-known acupuncture system for human patients which was developed by Dr. Yamamoto.ObjectiveMy aim was to transpose the human YNSA map onto canines and felines.MethodI started researching a canine/feline YNSA map in 2002. I investigated approximately 3,000 canines and felines for YNSA and 2,500 for Tail Acupuncture. The ratio of canines and felines was 6 to 4. I researched and found all the equivalent points by palpating animal patients on the basis of an exact Neck Diagnosis.ResultsI nearly completed the map in 2006. The points in the occipital region are incomplete and my research is still in progress. In the process of researching canine/feline YNSA points, I accidentally found the other microsystems around the tail and named it “Tail Acupuncture”.ConclusionsYNSA and Tail Acupuncture are acupuncture systems utilizing microsystems and support each other in canines and felines. The merits of YNSA and Tail Acupuncture are 1) immediate effects, such as in cases of lameness, 2) simplicity in finding the exact points to treat and 3) the scalp and the tail can be utilized separately or together as treatment zones, according to the situation.  相似文献

The locomotor system is one of the major fields of application for acupuncture. The results of the large acupuncture studies funded by German Health Insurances from 2000 until 2006 are impressive and repressive: they restrict acupuncture application by allocation of reimbursement and create the necessity of reorientation, since acupuncture can neither be adequately described nor prescribed solely on the basis of disease entities. Regarding these disease entities, it seems rather necessary to analyse the layers of problems and formulate a hierarchy of therapeutic goals instead. Only in this way the effects of acupuncture, related techniques and further therapeutic modalities can be matched with the set of objectives. The article presents general principles and follows their application from biological aspects to implications for the locomotor system and consequences for the application of physical therapy. The manual of acupuncture focuses on therapeutic effects and objectives first, and then goes on to sketch simple therapeutic strategies and finally complex approaches within acupuncture. These may encompass acupuncture, microsystem acupuncture and complex therapeutic modes.  相似文献

Background

Acupuncture as a regulative therapy is well-suited for the treatment of functional, reversible disorders. Additionally, the WHO recommends its application for pain therapy in cases of arthritis and back pain due to various causes. This case study should clarify which paths to take in the case of a multi-morbid patient suffering from chronic pains due to polyarthrosis.

Objective

Pain reduction and improvement of quality of life as well as improvement of sleep quality.

Methods

Annual treatment series consisting of 10 sessions each, one session per week.

Results

short-term pain reduction before undergoing endoprosthetic surgery; considerable improvement of general status and sleep.

Conclusions

Acupuncture may bring temporal relief in cases of chronic pain due to osteoarthritis and should therefore be applied in combination with western medicine. Acupuncture is particularly well-suited to treat the co-emergent vegetative symptoms.  相似文献

Background

Since the onset of her menopause about ten years ago, a sixty-year old patient has been suffering from hot flashes and sleep disorders causing her to become increasingly anxious and nervous. As the patient's mother had died of breast cancer, substitution of hormones was not advisable. Relaxation methods such as Yoga and Autogenic Training could only mildly alleviate the symptoms.

Objective

To effectively treat the sleep disorder, improve quality of life, lessen frequency and severity of hot flashes

Methods

Weekly sessions with ear- and body acupuncture for ten weeks

Results

After the third acupuncture session the patient reported a decrease of nightly waking episodes but suffered from acute pain in the neck as well as shoulder region. After nine therapy sessions, the patient reported a 50% decrease of nightly waking episodes. The hot flashes, however, remained unchanged.

Discussion

In this case, acupuncture significantly improved the patient's sleeping disorder. It also reduced the symptoms of anxiety and nervousness. Other menopausal symptoms such as hot flashes and dryness of mucous tissues, could not be influenced.  相似文献

目的揭示常见证候荷瘤小鼠神经-内分泌-免疫组织基因转录的总体特征。方法采用小鼠标准化四诊及辨证方法,及Gene Chip Mouse Exon1.0ST Array等技术,检测H22荷瘤小鼠早期邪毒壅盛(邪毒)和气虚、中期阳气虚、中晚期气阴阳虚等4个常见证候下丘脑、垂体、肾上腺、睾丸、脾脏、胸腺、肿瘤RNA的转录与剪接。结果正常昆明种雄性小鼠下丘脑、垂体、肾上腺RNA电泳的28S峰低于18S,而睾丸、脾脏、胸腺、肿瘤相反。肿瘤发生的早期,下丘脑、垂体、肾上腺基因表达模式发生显著改变,邪毒尤甚,出现了失代偿。下丘脑28SRNA迅速抬升并持续,气虚强于邪毒。垂体RNA总量降低,28S陡降,邪毒尤甚。肾上腺RNA电泳特征类似垂体,气虚与邪毒相近,中晚期气阴阳虚尤甚。睾丸变化不明显。随着病情发展,脾脏重量持续增加,而胸腺相反,重量持续下降,蛋白合成和糖代谢下降。肿瘤组织蛋白合成与糖代谢,邪毒大于气虚。以上7个组织与正常对照组相比,有9127个基因表达发生差异、51126个外显子剪接发生差异。结论神经-内分泌-免疫网络组织基因转录的差异是荷瘤小鼠不同证候内在重要的物质基础。  相似文献
