Objective: The 19 Mechanisms of Disease were first described in Huangdi Neijing. When examining Yixuexinwu, three descriptions that were different from Huangdi Neijing were found. Methods and Results: After examining the two books, three differences in the description of the 19 Mechanisms of Disease were discovered: 1) The upper and lower locations of dyspnea (喘症) are reversed. 2) The ratio of provisions for "fire (火)" and "cold (寒)" is different. 3) The organ affiliation for pain is different. Conclusion: 1) The upper and lower locations of dyspnea (喘症) are reversed. : Regarding external contraction dyspnea (外感喘), Yixuexinwu used the disease of the upper location (lung 上, 肺) in the same way as in Huangdi Neijing. In terms of internal damage (內傷喘), it was separately classified as a disease of the lower location (kidney 下, 腎). 2) The ratio of provisions for "fire (火)" and "cold (寒)" is different. : Arithmetically, if you round off the number after calculating the fraction, the difference between the two ratios becomes the same. Theoretically, five provisions of "fire" are replaced by four provisions of "heat (熱)", and the difference in ratios is exactly the same. Empirically, it emphasizes that there are more illnesses from fire and heat than from cold. 3) The organ affiliation for pain is different. : Huangdi Neijing described general inflammatory pain, while the Yixuexinwu described only stress-related abdominal pain (肝木乘脾 腹痛).

Objectives : The aim of this study was to evaluate the single oral dose toxicity and safety of Bojungikgi-tang (Buzhongyiqi-tang) and fermented Bojungikgi-tang (Buzhongyiqi-tang) extracts in male and female ICR mice. Methods : In the single oral dose toxicity study, non-fermented and fermented Bojungikgi-tang (Buzhongyiqi-tang) were administered to male and female ICR mice as an oral dose of 1250, 2500 and 5000 mg/kg. Changes of body weights, general behaviors, adverse effects and mortality were determined throughout the experimental period. Hematological parameters, serum chemistry, organ weights and necropsy findings were evaluated at the end of the experiment. Results : There was no mortality or sign of toxicity in the single oral dose toxicity study. There were also no significant differences in body weights, organ weights, and hematological parameters, serum chemistry values between treatment and control groups. Conclusions : The results obtained in this study suggest that the 50% lethal dose of fermented Bojungikgi-tang (Buzhongyiqi -tang) in both female and male mice can be considered as well over 5,000 mg/kg, so these medicines can be safe in clinics.

Objective : To study the effects and merits of the Yanzhen Therapy(眼針療法), Method : We researched through studying 28 kinds of literature. Result : 1. The Division of Eye Region(眼區分劃), the Position of Yanxue(眼穴定位) and the mutual connection with Internal Organ(臟腑) during the Yanzhen Therapy(眼鍼療法) were made according to Huata's Thesis, and were made by combining Neijing(內經) Theory about eyes, Yinyang and Five Elements(陰陽五行) Theory, Meridian & Zang-Xiang Theory(經絡臟象學說), the Five Circles & Eight Regions(五輪八廓學說) Theory, and the Zhouyi Eight Diagrams(周易八卦) Theory. 2. The assignment between the Internal Organ and Eye-Division(眼區分劃) was formed on the basis of the Five-Circles and Eight-Regions Theory in Ophthalmology(眼科五輪八廓學說) of Zhengzhizhunsheng(證治準繩). 3. The Assignment(排列) & Position(方位) of the Congenital Eight Diagram(先天八卦) and the Acquired Eight Diagram(後天八卦) have influenced the Division of Eight Eye Region(眼鍼八區) and the Position of Yanxue(眼穴定位) significantly. 4. It showed no difference with the Map of Eye Position of Eight-Division(八廓眼位圖) like as Shenshiyaohan(審視瑤函), Yinhaizhinan(銀海指南) and Sanzijing of Ophthalmology(眼科三字經). Conclusion : While combining organically with other methods of acupuncture, the Yanzhen Therapy(眼鍼療法) may have better clinical effectiveness, and is also expect to expand the clinical indication.

Regenerative medicine using stem cells from various sources are emerging treatment modality in several refractory diseases in veterinary medicine. It is well-known that stem cells can differentiate into specific cell types, self-renew, and regenerate. In addition, the unique immunomodulatory effects of stem cells have made stem cell transplantation a promising option for treating a wide range of disease and injuries. Recently, the medical demands for companion animals have been rapidly increasing, and certain disease conditions require alternative treatment options. In this review, we focused on stem cell application research in companion animals including experimental models, case reports and clinical trials in dogs and cats. The clinical studies and therapeutic protocols were categorized, evaluated and summarized according to the organ systems involved. The results indicate that evidence for the effectiveness of cell-based treatment in specific diseases or organ systems is not yet conclusive. Nonetheless, stem cell therapy may be a realistic treatment option in the near future, therefore, considerable efforts are needed to find optimized cell sources, cell numbers and delivery methods in order to standardize treatment methods and evaluation processes.

Present article reviews about clinical pharmacology of mycophenolic acid (MPA), the active form of mycophenolate mofetil (MMF), as widely used component of immunosuppressive regimens in the organ transplantation field. MMF, used alone or concomitantly with cyclosporine or tacrolimus, has approved in reducing the incidence of acute rejection and has gained widespread use in solid organ such as kidney, heart and liver transplantation. The application of MPA and development of MMF has shown a considerable impact on immunosuppressive therapy for organ transplantation as a new immunosuppressive agent with different mechanism of action from other drugs after early 1990s. In particular aspect, use of MMF, a morpholinoethyl ester of MPA, represented a significant advance in the prevention of organ allograft rejection as well as allograft and patient survival. In considering MMF clinical data, it is important to note that there is a strong correlation between high MPA area under curve(AUC) values and a low probability of acute allograft rejection. Individual trials have shown that MMF is generally well tolerated and revealed that MMF decreased the relative risk of developing chronic allograft rejection compared with azathioprine. Recent clinical investigations suggested that improved effectiveness and tolerability will results from the incorporation of MPA therapeutic drug monitoring into routine clinical practice, providing effective MMF dose individualization in renal and heart transplant patients. Therefore, MMF has a selective immunosuppressive effect with minimal toxicity and has shown to be more effective that other agents as next step of immunosuppressive agents and regimens that deliver effective graft protection and immunosuppression along with a more favorable side effect.

The electrical properties of pig internal organs including lung, liver, heart, kidney, blood, stomach, and small intestine are measured using an open-ended coaxial probe and an improved virtual transmission-line model. The measured complex permittivities of the pig organs are compared with the given values of the corresponding human organs. A similarity between these values is confirmed. For organs such as lung, liver, heart, and kidney that have regular texture and contents, the complex permittivities are almost identical to those of the corresponding human organs. The complex permittivities of human and pig blood are also very close in value. However, relatively large deviations are observed for the cases of stomach and small intestine because the internal contents of these organs significantly affect the measured electrical properties.

A complicated case of echinococcosis with multiple organ involvement is reported in a 53-year-old businessman who frequently traveled overseas, including China, Russia, and Kazakhstan from 2001 to 2007. The patient was first diagnosed with a large liver cyst during a screening abdomen ultrasonography in 2011, but he did not follow up on the lesion afterwards. Six years later, dizziness, dysarthria, and cough developed, and cystic lesions were found in the brain, liver and lungs. The clinical course was complicated when the patient went through multiple surgeries and inadequate treatment with a short duration of albendazole without a definite diagnosis. The patient visited our hospital for the first time in August 2018 due to worsening symptoms; he was finally diagnosed with echinococcosis using imaging and serologic criteria. He is now on prolonged albendazole treatment (400 mg twice a day) with gradual clinical and radiological improvement. A high index of suspicion is warranted to early diagnose echinococcosis in a patient with a travel history to endemic areas of echinococcosis.
