  • The complicated helical flow formed in the regenerative turbomachines is usually decomposed into a peripheral component and a circulatory component. On the basis of the momentum exchange theory, the circulatory flow plays a critical role of imparting angular momentum to the peripheral flow. Therefore, the accuracy of performance prediction is dominated by the circulatory flow modeling. Until now the circulatory flow has been accounted of a standstill flow normal to the peripheral flow. However, the circulatory path from the impeller exit to the re-entrance inlet is exposed to the adverse pressure gradient, so it would be more realistic to describe that the circulatory flow is formed on the skewed plane not perpendicular to the peripheral flow. Present study suggests new circulatory flow loss model including the effect of adverse pressure gradient and modifies the effective circulatory flow rate and circulatory pivot which were previously published.

  • The purpose of establishing the circulatory disease surveillance system in Korea is to ensure that the problems of circulatory disease importance are being monitored efficiently and effectively. The goals of circulatory disease surveillance system are to monitor the epidemiological trends of circulatory disease and to evaluate the outcome of health activity for controlling circulatory diseases. Surveillance system are being updated to achieve the needs for the integration of the surveillance and information system, the establishment of data standards, the electronic exchange of data, and changes in the goals of circulatory disease surveillance system to facilitate the response of this system to manage the national health problem effectively. This article provides the target diseases and determinant indicators to be monitored, structure of circulatory disease surveillance system, and many tasks and related activities that should be applied to this system.

  • This is a case report on a deep vein thrombosis(DVT) patient whose pain, numbness, and swelling in the left leg have been decreased with Korean Medicine. The 59 year-old male patient who was diagnosed with DVT and showed the classic symptoms of DVT(pain, numbness and swelling in the left leg). Although he was treated with medication(100mg of aspirin, 20mg of rivaroxaban) for five weeks, his symptoms did not improved. Then, he was gaven Sunkihwalhyul-tang three times a day and Jungsongouhyul pharmacopuncture once a day for two months. Conservative therapy including leg elevation and an elastic stocking was co-administered. During our treatment period, the size of the thrombus in the left external iliac vein was decreased according to sonography compared with the pre-hospital's sonography, and the patient felt his symptoms had improved. This case report suggests Korean Medicine may play a role in improving the deep vein thrombosis symptoms.

  • This study is aimed to report two cases of chronic kidney disease treated with Korean traditional medicine. We treated the patients with traditional herbal medicine and other treatments including acupuncture. We measured serum creatinine, estimated glomerular filtration rate(eGFR), blood urea nitrogen(BUN), albumin, red blood cell count(RBC), hemoglobin for several times during admission. Case 1 patient was diagnosed with right medulla infarction, bladder stone, chronic kidney disease. The symptoms were quadriplegia, right side dysesthesia, drowsiness and edema. Case 2 patient was diagnosed with acute cerebral infarction, hypertension, chronic kidney disease. The symptoms were right side weakness, delusion, anorexia, low back pain. Case 1 patient was hospitalized for 80 days, and case 2 patient was for 31 days. Korean traditional medicine decreased serum creatinine and BUN level, improved eGFR, increased RBC and hemoglobin. The symptoms of chronic kidney disease such as edema, general body weakness and anorexia were also improved. These cases suggest that Korean traditional medicine can be effective and safe for patients with chronic kidney disease.

  • Objectives This study reports three cases of pressure ulcer treated with Hwangryunhaedok-tang pharmacopuncture. Methods Three patients with pressure ulcers were treated by Hwangryunhaedok-tang pharmacopuncture and Jaungo at the Oriental Medicine Hospital of Daejeon University. Hwangryunhaedok-tang pharmacopuncture and Jaungo was administrated once a day with simple dressing. Thereafter, we observed the pressure ulcers macroscopically. Results and Conclusions After 3 weeks, wound sizes were reduced and tissue regeneration was accelerated. In conclusion, Hwangryunhaedok-tang pharmacopuncture and Jaungo are effective to treat pressure ulcers, but more studies will be required to validate its use in pressure ulcers.

Methods: A 51-year-old woman with dizziness, diagnosed with hippocampal sclerosis, was treated with herbal medication, acupuncture, and moxibustion. Her improvement was evaluated by a balance test, NRS, and the percentage of dizziness severity compared to that on her admission day. Results: Improvement in the balance test result and NRS, and a decrease of percentage of dizziness severity, were observed after treatment with Korean medicine. Conclusions: This study suggests that treatment with Korean medicine may be an effective therapy for dizziness due to hippocampal sclerosis.

  • Objectives: The aim of this research was to investigate and review the trends in recent clinical studies of multiple system atrophy (MSA) in China. Methods: We searched for clinical studies discussing Oriental medicine-based treatments for MSA in the China National Knowledge Infrastructure (CNKI) database. The search focused on the authors; publication year; type of study; method and duration of treatment; evaluation criteria; and results of the selected articles. Results: Among the articles retrieved from the database, eight case series, two randomized controlled trials (RCTs), and one non-randomized controlled trial (nRCT) were analyzed. Eight articles used acupuncture; ten used herbal medicine. The most frequently used acupoints were GV20, GV24, GB20, PC6, Hyeopcheok Acupoint, CV4, EX-HN3, and GV17. Jihwangeumja was the most commonly used herbal prescription. All 13 studies confirmed the efficacy of Oriental medicine treatments. Conclusions: More varied and scientifically designed clinical studies are required to develop treatments for MSA. The results of this study may provide guidance for further studies of MSA.

  • In Oriental medicine, the subjective process of diagnosis often makes it difficult to explain the indications objectively, in spite of its excellent therapeutic value. The authors' objective Was to present more objective indications of Chongpesagan-tang(淸肺瀉肝湯), a prescription predominantly used to treat stroke in Oriental Medicine, We analyzed clinical symptoms of 105 patients who were hospitalized in the Department of Circulatory Internal Medicine, College of Oriental Medicine. Kyung Hee University, Seoul, who were given Chongpesagan-tang and improved without side effects, The symptoms analyzed included general symptoms which are usually checked in the process of Oriental Medicine Diagnosis: the so called Four Diagnosis(四診). We rearranged and selected symptoms which were predominantly found among other symptoms. We found some symptoms of which the patients frequently complained: sweating 84%, red tongue 74%, white tongue coat 65%, constipation 35%, tight pulse 21%, headache 20%, thirst 20%, chest discomport 17%, etc, We believe that these suggest an objective indication of Chongpesagantang.

  • Objectives : This study was carried out to examine toxic effect of Sintongchukeo-tang on cultured mouse spinal sensory neurons inhibited by neurotoxicity induced by hydrogen peroxide. Methods : MTT assay, NR assay, LDH and neurofilament assay were performed after spinal sensory neurons were preincubater with various concentrations of Sintongchukeo-tang water extract before treatment of cells with hydrogen peroxide. Results : Hydrogen peroxide induced ceil degeneration such as the decrease of cell viability was measured by MTT and NR assay in the cultured mouse spinal sensory neurons. Sintongchukeo-tang water extract was effective in the decrease of LDH activities of neurons produced by hydrogen peroxide. Sintongchukeo-tang water extract was effective in the increase of amount of neurofilaments damaged by hydrogen peroxide. Conclusions : From the above results, it is suggested that hydrogen peroxide induces the inhibition of cell viability in cultured mouse spinal sensory neurons and Sintongchukeo-tang water extract was effective in cultured neurons damaged by hydrogen peroxide.
