Objectives : Sweet bee venom is made by removing allergen from the bee venom through gel filtration chromatography and propionic acid/urea polyacrylamide gel electrophoresis. The aim of this study was to verify allergy inhibitory action in Sweet Bee Venom in which the allergy causing enzyme is removed. Methods : 95 healthy adult men and women were selected through a survey whom had never received the bee venom therapy in the past. The concentration of bee venom pharmacopuncture and Sweet BV pharmacopuncture was equally at 0.1mg/ml and the experiment was conducted as the double blind test. Experiment groups were classified into low dosage groups(0.1ml for both bee venom pharmacopuncture and Sweet BV) and high dosage groups where 0.4ml of respective administrations were rendered made observations for allergic responses. Results : Participants of the study was comprised of 71 men and 24 women with the average age of 29.0 years. According to results of the low dosage groups, Sweet BV group showed significant reduction in pain after 4 hours and 24 hours compared to the bee venom pharmacopuncture group. Other allergic responses were insignificant between the groups. For the high dosage groups, Sweet bee venom group showed reduction in pain after 30 minutes and 4 hours. Other allergic responses such as edema, itchiness, dizziness from hypersensitivity, and fatigue were significantly lower in the Sweet bee venom administered group after 30 minutes. Conclusions : As a result of removed allergen, Sweet bee venom significantly inhibits allergic responses both locally and throughout the body. This indicates wider and easier application of Sweet bee venom for the symptoms applicable to the bee venom pharmacopuncture. Further comparative studies should be conducted to yield more objective verification.

Objective : This is a cadaver study to assess the accuracy of three cervical screw insertion techniques; the blind technique [Group I], the laminotomy technique [Group II], and the funnel technique [Group III]. Methods : Ten human cadavers embalmed with formaldehyde were prepared. After exposing the spinous processes, the laminas and the lateral masses, titanium alloy transpedicular screws were inserted from C3 to C7. A total of 100 pedicles were ramdomly assigned to one of three techniques [the blind technique : 31 screws, the laminotomy technique : 51 screws, the funnel technique: 18 screws]. Axial computed tomography with 1-mm slices, and sagittal and coronal reformation were performed to identify the accuracy of the screw insertion and the anatomic relationships. Results : In Group I, 9 screws [29%] were either contained within or penetrated less than 1mm, which were rated as successful. In Group II, 24 screws [47%] were successful. In Group III, 16 screws [89%] were successful. In the multiple comparison, there was a statistically significant difference between Groups I and III and between Groups II and III [$X^2$ test and Bonfenoni test]. Conclusion : The funnel technique can help a surgeon's understanding about the cervical pedicle more precisely than the other two techniques. The funnel technique is less dependent on lateral soft tissue retraction state.

Background: Antihyperglycemic effects of Panax ginseng berry have never been explored in humans. The aims of this study were to assess the efficacy and safety of a 12-wk treatment with ginseng berry extract in participants with a fasting glucose level between 100 mg/dL and 140 mg/dL. Methods: This study was a 12-wk, randomized, double-blind, placebo-controlled clinical trial. A total of 72 participants were randomly allocated to two groups of either ginseng berry extract or placebo, and 63 participants completed the study. The parameters related to glucose metabolism were assessed. Results: Although the present study failed to show significant antihyperglycemic effects of ginseng berry extract on the parameters related to blood glucose and lipid metabolism in the total study population, it demonstrated that ginseng berry extract could significantly decrease serum concentration of fasting glucose by 3.7% (p = 0.035), postprandial glucose at 60 min during 75 g oral glucose tolerance test by 10.7% (p = 0.006), and the area under the curve for glucose by 7.7% (p = 0.024) in those with fasting glucose level of 110 mg/dL or higher, while the placebo group did not exhibit a statistically significant decrease. Safety profiles were not different between the two groups. Conclusion: The present study suggests that ginseng berry extract has the potential to improve glucose metabolism in human, especially in those with fasting glucose level of 110 mg/dL or higher. For a more meaningful benefit, further research in people with higher blood glucose levels is required.

This study aimed to prove the effects of acupuncture treatment on acupoint Joksamni(ST36) related to gastrointestinal movement. Electrogastrogram (EGG) data were obtained in 11 healthy subjects treated by real or sham needle in single-blinded condition for 40 min, including before, during acupuncture treatment, and after removing needle. According to frequency analysis of EGG, median frequency(MF) was increased by real needle in 4 subjects, MF for another 2 subjects were increased by real and sham needle and no trend shift in MF showed in other 5 subjects. Our result showed that acupuncture treatment on Joksamni has some effects on gastrointestinal movement. In this study we have applied both real acupuncture and sham acupuncture on the same subjects. So its blinding was regarded as good but was effective in about 36%~55%. Two subjects were assumed that they showed placebo effects on both real and sham acupuncture. Therefore it is necessary to perform further study on case-control and a larger number of subjects with functional dyspepsia, in order to confirm our findings.

Hydrocarbons in soybeans were analyzed to determine whether the hydrocarbons can be applied for detecting post-irradiation of soybeans. Yellow and green soybeans were irradiated at 0.5, 1, 3, and 6 kGy. Fats were extracted with hexane and then hydrocarbons were separated from the fat through Florisil column. The hydrocarbons were analyzed with GC. Hydrocarbons 17:2, 16:3, 17:1, and 16:2 were detected in the samples irradiated at 0.5 kGy or higher, but not in the unirradiated ones. The detection levels of hydrocarbons increased with the dose of the irradiation. When unirradiated or irradiated soybeans were roasted or boiled, these hydrocarbons were detected in the samples irradiated at 1 kGy or higher, but not in the unirradiated ones. A blind test confirmed that the hydrocarbon determining method could detect the soybeans irradiated at 1 kGy.

A Hoffman 3D Brain Phantom was used to evaluate two PET/CT scanners, BIO_40 and D_690, according to the radiation dose of CT (low, medium and high) at a fixed kilo-voltage-peak (kVp) with the tube current(mA) varied in 17~20 stages(Bio_40 PET/CT scanner: the tube voltage was fixed to 120 kVp, the effective tube current(mAs) was increased from 33 mAs to 190 mAs in 10 mAs increments, D_690 PET/CT scanner: the tube voltage was fixed to 140 kVp, tube current(mA) was increased from 10 mAs to 200 mAs in 10 mAs increments). After obtaining the PET image, an attenuation correction was conducted based on the attenuation map, which led to an analysis of the difference in the image. First, the ratio of white to gray matter for each scanner was examined by comparing the coefficient of variation (CV) depending on the average ratio. In addition, a blind test was carried out to evaluate the image. According to the study results, the BIO_40 and D_690 scanners showed a <1% change in CV value due to the tube current conversion. The change in the coefficients of white and gray matter showed that the Z value was negative for both scanners, indicating that the coefficient of gray matter was higher than that of white matter. Moreover, no difference was observed when the images were compared in a blind test.

Background: In Korean medicine, carpal tunnel syndrome is treated by stimulating the acupoints around the wrist. Although a deep understanding of anatomy and guidance is needed to stimulate these acupoints to avoid undesirable side-effects, currently there are no published guidelines for acupotomy treatment. The aim of this study is to evaluate the effectiveness and safety of fluoroscopy-guided acupotomy compared with conventional acupotomy treatment. Methods: This is a randomized, patient-assessor, patient blind, parallel clinical trial. A total of 30 patients will be enrolled at Wonkwang University Gwangju Hospital, and will be allocated to either an experimental group or a control group. The experimental group will be treated using fluoroscopy-guided acupotomy and the control group will be treated using the conventional acupotomy method. Results: The primary outcome measure will be identification of a cross-section area of the median nerve measured by ultrasonography, and the secondary outcome measure will be the alleviation of pain measured by the Visual Analogue Scale, improvement in the Nerve Conduction Study, Tinel test, Phalen's test, EuroQol 5-dimension scale, and Boston Carpal Tunnel Questionnaire score. Safety components will be measured by monitoring vital signs, electrocardiographs, blood tests, general chemical tests, urine tests and pregnancy tests. In addition, observations for adverse effects will be performed during the trial. Conclusion: This study will provide a more effective, and less harmful way of treating carpal tunnel syndrome compared with conventional acupotomy. Fluoroscopy-guided acupotomy will help practitioners to be accurate in direction and depth of the needle for treating carpal tunnel syndrome.
