  • Background: Telbivudine is a nucleoside analogue used for the treatment of chronic hepatitis B, but it often develops mitochondrial toxicity leading to symptomatic myopathy. In this study, three patients with telbivudine induced myopathy were enrolled in order to investigate the nature and pathogenesis of mitochondrial toxicity caused by long-term use of telbivudine. Methods: Clinical features, laboratory findings, muscle pathology, and quantitation of mitochondrial DNA were studied in three patients. Results: Patients presented with progressive muscle weakness with high serum creatine kinase levels. Light microscopic findings of muscle pathology showed ragged red fibers that reacted strongly with succinate dehydrogenase stain, but negative for cytochrome c oxidase activities. Electron microscopy revealed abnormal mitochondrial accumulation with rod shaped inclusions. The quantitative peroxidase chain reaction showed a depletion of mitochondrial DNA in skeletal muscle of the patients. Conclusions: Nucleoside analogues including telbivudine are potent inhibitors of viral DNA polymerases. However, they are not specific for viral DNA and can disturb mitochondrial replication at the same time. All nucleotide analogues should be used with close clinical observation in order to avoid development of mitochondrial myopathy.

  • The purpose of this study is to design electrical stimulation system fur stroke patients with pharyngeal dysfunction(dysphagia). Dysphagia is that the food has trouble in passing to the mouth from the stomach. Although we have many treatment methods for dysphagia, electrical stimulation system will be useful for stroke patients having dysphagia. Electrical stimulation system can be divided into body and electrodes. The body stimulation is composed to frequency counter, time control and current measurement part. These parts are to control the frequency, stimulating time and current intensity And they can be variable according to the patient's clinical assessment. The electrode plays a role to deliver the current from the system to the muscle. Also the position of the electrode can be variable according to the treatment method. We performed the clinical experiment with stroke patients who had swallowing disorder. The videofluoroscopy was used fur the observation. From the result of clinical experiment based on electrical stimulation, we expected that the dysfunction(in pharynx) level of the patient could be improved. However we could not have enough effectiveness of the treatment because of the number of patients, patient's adaptation and treatment period. We will design the optimized electrical stimulation system based on enough clinical experiment in the future.

  • A 13-month-old intact female poodle dog presented with an acute history of circling and seizure episodes. On the basis of the results of neurologic examination combined with magnetic resonance imaging and cerebrospinal fluid analysis (CSF), meningoencephalitis of unknown etiology (MUE) was suspected. Therapy with mycophenolate mofetil plus prednisolone was initiated, following which the clinical signs showed improvement for only one month before gradually worsening again. Acute progression of the clinical disease was observed, and the patient was euthanized 91 days after initial presentation. This case was definitively diagnosed as necrotizing meningoencephalitis (NME) according to the results of post-mortem histopathological examination. This report describes the clinical findings, serial magnetic resonance imaging (MRI) characteristics, and histopathological changes in a case of acute NME.

  • Objectives: This study aimed to evaluate the potential toxicity of a recently developed and clinically used No-Pain pharmacopuncture (NPP) solution. We also assessed the lethal dose of the NPP agent following a single intramuscular injection in Sprague-Dawley (SD) rats. Methods: Animals were divided into two groups: the NPP test material group and the normal saline control group. A single intramuscular injection of the NPP agent (1.0 mL/animal) was administered to rats of the NPP test material group. The control group rats received the same volume of normal saline. Both female and male rats were included in each group. All rats were monitored for clinical signs and body weight changes for 14 days after administration of the test substance or saline. At the end of the observation period, a gross necropsy was conducted and localized tolerance at the injection site was analyzed. Results: No mortality was observed in the NPP test material and control groups. Moreover, no test substance-related effects were observed on clinical signs, body weight, necropsy findings, and localized tolerance at the injection site. Conclusion: The approximate lethal dose of the NPP agent is greater than 1.0 mL/animal under the conditions used in this study. Additional toxicity evaluations and clinical studies are needed to confirm the safety of NPP use in clinical practice.

  • The purpose of this study is to analyze trends in domestic and international clinical research studies on pharmacopuncture treatment for fractures. We searched five online databases (PubMed, CNKI, RISS, KISS, and OASIS), and selected a total of 13 clinical research studies from Korea and China. Selected studies were analyzed according to publication year, subject, intervention, treatment method, evaluation scale, adverse event, risk of bias, etc. A total of 10 case studies and 3 randomized controlled trials were included. The study subjects were more often female, and the most common type of fracture was vertebral compression fracture. In Korea, herbal medicine preparations and bee venom were used for pharmacopuncture solution, whereas in China, both herbal medicine preparations and Western medicine preparations were used. All studies commonly used local acupoint needling, and in most cases, the treatment period for case study was less than 1 month, and the observation period of randomized controlled trials was diverse. The most frequently used evaluation scale was numeric rating scale, adverse events were mentioned in only three studies, and no adverse events were reported. Overall risk of bias of all included randomized controlled trials was judged "some concerns". According to this study, pharmacopuncture treatment for fractures was found to be relatively effective and safe, but research that complements the limitations of this study is needed.

  • PURPOSE. The objective of this study was to determine the cumulative survival rate (CSR) and associated risk factors of Implantium implants by retrospective clinical study. MATERIALS AND METHODS. Patients who received Implantium implants (Dentium Co., Seoul, Korea) at Korea University Guro Hospital from 2004 to 2011 were included. The period between the first surgery and the last hospital visit until December 2015 was set as the observation period for this study. Clinical and radiographic data were collected from patient records, including all complications observed during the follow-up period. Kaplan-Meier analysis was performed to examine CSR. Multiple Cox proportional hazard model was employed to assess the associations between potential risk factors and CSR. RESULTS. A total of 370 implants were placed in 121 patients (mean age, 56.1 years; range, 19 to 75 years). Of the 370 implants, 13 failed, including 7 implants that were lost before loading. The 10-year cumulative survival rate of implants was 94.8%. The multiple Cox proportional hazard model revealed that significant risk factor of implant failure were smoking and maxillary implant (P<.05). CONCLUSION. The 10-year CSR of Implantium implants was 94.8%. Risk factors of implant failure were smoking and maxillary implant.

  • Clinical observation was done on 290 cases of patients who were diagnosed as CVA with brain CT, TCD, MRI scan and clinical observation. They were hospitalized in the oriental medical hospital of Kyung-Won University from 1st January to 31st December in 1996. 1. The cases were classified into the following kinds : cerebral infarction, cerebral hemorrhage, and transient ischemic attack. The most case of them was the cerebr진 infarction. 2. There is no significant difference in the frequency of strokes in male and female. And the frequency of strokes was highest in the aged over 50. 3. In cerebral infarction the most frequent lesion was the territory of middle cerebral artery, and in cerebral hemorrhage the most frequent lesion was the basal ganglia. 4. The most ordinary preceding disease was hypertension, and the next was diabetes. 5. The rate of recurrence was high in cerebral infarction. 6. The frequency of strokes seems to have no relation to the season. 7. The cerebral infarction occurred usually in resting and sleeping, and the cerebral hemorrhage in acting. 8. The course of entering hospital, most patients visited this hospital as soon as CVA occurred. And the half of patient visited this hospital within 2 days after CVA attack. 9. In the cases of patients who were unconscious at the admission, the prognosis was worse than that of the alert patients. 10. The common symptoms were motor disability and verbal disturbance. 11. The average duration of hospitalization was 27.4 days, and in case of cerebral hemorrhage the duration was prolonged. 12. The average time to start physical therapy was 13.3rd day after stroke in cerebral infarction and it was 19.9th day after stroke in cerebral hemorrhage. 13. The common complications were urinary tract infection, pneumonia, myocardial infarction and so on. 15. At the time of entering hospital, in most cases the blood pressure was high, but blood pressure was well controlled at the time of discharge. 16. Generally reported, hypercholesterolemia and hypertriglyceridemia are usually found in cerebral infarction. But in this study, they were found more frequently in cerebral hemorrhage than in infarction. 17, In the most cases, western and oriental medical treatments were given simultaneously. 18. In acute or subacute stage, the methods of smoothening the flow of KI(順氣), dispelling phlegm(祛痰), clearing away heat(淸熱) or purgation(瀉下) were frequently used. And in recovering stage, the methods of replenishing KI(補氣), tonifying the blood(補血) or tranquilization(安神) were frequently used.
