  • The objective of this study is the evaluation of the performance of a large-scale respirometer (LSR) of 17.7 L in the determination of the methane generation rate constant (k) values. To achieve this objective, a comparison between anaerobic (GB21) and LSR tests was conducted. The data were modeled using a linear function, and the resulting correlation coefficient ($R^2$) of the linear regression is 0.91. This result shows that despite the aerobic conditions, the biodegradability values that were obtained from the LSR test produced results that are similar to those from the GB21 test. In this respect, the LSR test can be an indicator of the anaerobic biodegradability for landfill waste. In addition, the results show the high repeatability of the tests with an average coefficient of variance (CV) that is lower than 10%; furthermore, the CV for the LSR is lower than that of the GB21, which indicates that the LSR-test method could provide a better representation of waste samples. Therefore, the LSR method allows for both the prediction of the long-term biodegradation potential in a shorter length of time and the reduction of the sampling errors that are caused by the heterogeneity of waste samples. The k values are $0.156y^{-1}$ and $0.127y^{-1}$ for the cumulative biogas production (GB21) and the cumulative oxygen uptake for the LSR, respectively.

  • We report a preliminary fMRI evidence of modulation of somatomotor areas by acupuncture in GB34 acupoint. GB34, located in the back of the knee, is known to be effective in recovering motor function after stroke. Using 3T MR scanner, functional MR imaging was performed in five normal volunteers in two stimulation paradigms; acupuncture manipulation on GB34 and sham points. Group analysis from five individuals showed that bilateral sensorimotor areas (BA 3,4,6 and 7) showed stimulation related BOLD signal contrast of approximately 6% whereas very few areas were activated when sham stimulation is given. Our results suggest that acupuncture fMRI study can be safely conducted in 3T environment, and stimulation in GB34 modulate the cortical activities of the somatomotor area in human.

  • In this study, simple sequence repeat (SSR) analyses were utilized for evaluation of genetic diversity and discrimination of 17 accessions. Five cultivars, which were developed from Korea, and 12 foreign accessions, which were collected from China, Japan, Russia and USA, were evaluated by nine markers out of 22 SSR markers. A total of 39 alleles were detected, ranging from 2 to 8, with an average of 4.3 alleles per locus. The expected heterozygosity and PIC values were 0.627 and 0.553, with a range from 0.21 (GB-PG-078) to 0.76 (GB-PG-142) and from 0.19 (GB-PG-078) to 0.70 (GB-PG-142), respectively. Four makers out of nine SSR markers, GB-PG-026, GB-PG-043, GB-PG-142 and GB-PG-177, were selected as key factors for discrimination of Korean ginseng cultivars and foreign accessions. All of Korean ginseng cultivars and foreign accessions were individually by the combination of four SSR markers. Consequently, the SSR markers developed in this study may prove useful for the evaluation of genetic diversity and discrimination of Korean ginseng cultivars and foreign accessions.

  • Objectives : The authors aimed at contributing to the safety of acupuncture in the clinic by analyzing the information of contraindicated acupoints described in Uihakipmun. Methods : We investigated the contents related acupuncture contraindications in Uihakipmun, categorized the contraindicated acupoints by site and identified whether they can cause adverse events from the anatomical point of view. Results : In Uihakipmun, 49 acupoints - BL6, BL8, BL9, ST1, SI18, BL1, BL2, TE18, TE19, TE20, GB1, GB3, GV22, GV24, ST12, ST9, TE16, GV6, BL15, BL30, CV17, LU2, GB22, SP16, CV8, CV9, CV15, KI11, ST30, SP11, BL56, GB32, GB33, GB42, LI13, HT2, TE8, GV17, GB18, EX-HN11, GB21, GV11, GV10, ST17, CV5, CV1, ST42, SP6, LI4 - were described as contraindicated acupoints. Among them, the contraindications induced by acupuncture treatment were described for just 5 acupoints. Anatomically, acupuncture stimulation at the contraindicated acupoints can cause organ, nerve or vessel damage near the acupoints. And the number of contraindicated acupoints in Uihakipmun was increased compared to those in Hwangjenaegyeong, Chimgugabeulgyeong, Bigeupcheongeumyobang, Donginsuhyeolchimgudogyeong and Chimgujasaenggyeong. Conclusions : In Ming dynasty, the knowledge associated with adverse events on acupuncture was increased by the accumulation of medical knowledge. Acupuncture stimulation at the contraindicated acupoints described in Uihakipmun can cause tissue damage, therefore we should perform acupuncture procedure carefully to avoid adverse events when stimulating the contraindicated acupoints.

  • Objectives: Whiplash injury is one of the major diseases in recent times because of increasing traffic accidents. This review aims to analyze the overall trend of studies on pharmacopuncture for whiplash injury after traffic accidents. Methods: We searched through 4 Korean electronic databases from 2001 up to October 2020 for relevant clinical studies for whiplash injury after traffic accidents, regardless of the patients' age, gender, or race. We included studies that had an intervention group receiving pharmacopuncture therapy with or without other additional treatments, and also included studies that had a control group receiving sham treatment or active treatment such as physical therapy and herbal medication. For the clinical outcomes, we did not place any restrictions on evaluation scales if they are objective metrics. Results: We included 6 randomized controlled trials (RCTs) and 10 non-randomized controlled trials (nRCTs). 10 nRCTs were divided into 4 categories that were case-control studies, case series, case report, and retrospective observational study. In RCTs, Hwangryun-haedoktang (黃蓮解毒湯) pharmacopuncture was the most frequently used. In nRCTs, Jungsong-ouhyul (中性瘀血) pharmacopuncture, and bee venom pharmacopuncture were the most frequently used. As target points of Hwangryun-haedoktang pharmacopuncture, Ashi-points, Jianjing (GB21), and Fengchi (GB20) were the most frequently used. As target points of Jungsong-ouhyul pharmacopuncture, Ashi-points were the most frequently used. And as target points of Bee venom pharmacopuncture, Fengchi (GB20) was the most frequently used. Conclusion: Hwangryun-haedoktang pharmacopuncture, bee venom pharmacopuncture, and Jungsong-ouhyul pharmacopuncture were mainly used for whiplash injury, and their usual target points were Jianjing (GB21), Fengchi (GB20), and Ashi-points. However, a high level of evidence should be conducted through studies with systematic methodology in the future.

  • Objectives : The aim of this study was to evaluate the efficacy of Hwangnyeonhaedok-tang (HH) and Geongangbuja-tang (GB) on the plasma hormone level in mice exposed to cold stress. HH and GB are the representative prescriptions of cold and hot property, respectively. Methods : We established cold condition by confining ICR mice to a $4^{\circ}C$ cage for 24 hours, ICR mice were given a HH (100, 300, 1000 mg/kg) or GB (100, 300, 1000 mg/kg) extract orally twice a day for three consecutive days. From the second day, they were given cold stress ($4^{\circ}C$) for twenty four hours. To measure the plasma corticosterone, insulin, thyroxine, epinephrine and norepinephrine levels of mice, their blood samples were collected from cardiac puncture, immediately centrifuged at $4^{\circ}C$. The protein level of HSP70 and JNK was examined using western blot analysis in cortex and hypothalamus. Results : Oral administration of GB more significantly reduced plasma corticosterone level raised by cold stress than HH. Gardeniae Fructus (CJ), the constituent of HH, significantly increased the thyroxine level. Western blot analysis showed that cold stress-induced Heat shock protein 70 (HSP70) expression was increased by HH and GB, HH decreased JNK expression and GB increased JNK expression dose-depently in hypothalamus. Scutellariae Radix (HG), Zingiberis Rhizoma (GG) and Aconiti Tuber (BJ) decreased HSP70 in hypothalamus and GG, BJ decreased HSP70 in cortex as well. Conclusions : These results suggest Geongangbuja-tang (GB) is more effective for ameliorating the stress response caused by cold stress.

  • Fabry disease is a hereditary lysosomal storage disorder caused by the reduction or absence of lysosomal enzyme alpha-galactosidase A and the accumulation of glycosphingolipids, such as globotriaosylceramide (Gb3), in various organs, including the heart. The prevention of cardiac involvement in Fabry disease can only be achieved by enzyme replacement therapy (ERT), and the method of assessing the efficacy of ERT should be confirmed. Changes in the electrocardiogram, such as the shortening of PQ interval, prolongation of QTc and repolarization abnormalities as well as left ventricular hypertrophy in voltage criteria, can be used to identify Fabry disease patients; however, the usefulness of electrocardiograms for evaluating the efficacy of ERT is limited. The assessment of left ventricular hypertrophy using echocardiography has been established to evaluate the efficacy of ERT during long-term period. A new technique involving speckled tracking method might be useful for detecting early cardiac dysfunction and identifying the effect of ERT for a relatively short period. The estimation of left ventricular hypertrophy using cardiac magnetic resonance (CMR) is also useful for assessing the efficacy of ERT. Identifying late gadolinium enhancement in CMR may affect the effectiveness of ERT, and the new technique of T1 mapping might be useful for monitoring the accumulation of Gb3 during ERT. Histopathology in cardiac biopsy specimens is another potentially useful method for identifying the accumulation of GB3; however, the use of histopathology to evaluate of the efficacy of ERT is limited because of the invasive nature of an endomyocardial biopsy.
