Objectives: To evaluate the reliability of a pattern identification tool for benign prostatic hyperplasia and to examine the relationship between pattern identification tool readings and IPSS and uroflowmetry. Methods: We analyzed 56 patients diagnosed with benign prostatic hyperplasia from December 27th, 2017 to December 26th, 2018 by two different Korean medical doctors and followed with a pattern identification tool and by IPSS and uroflowmetry. One week later, the patients were retested to analyze the reliability of the pattern identification tool, determined with the intraclass correlation coefficient (ICC) using the test-retest method. The correlation between IPSS and uroflowmetry was analyzed with the Pearson coefficient. Result: The reliability of the pattern identification tool for benign prostatic hyperplasia was evaluated as "poor agreement beyond chance" (ICC=0.349). The reliability of each pattern identification score was evaluated as "good" for Yang Deficiency of Kidney, Yin Deficiency of Kidney, Deficiency of Middle Qi, and Dampness-heat of Lower Energizer. The internal consistency was evaluated as "good" for Yang Deficiency of Kidney, Yin Deficiency of Kidney, and Dampness-heat of Lower Energizer, and as "excellent" for Deficiency of Middle Qi. The correlation between pattern identification and IPSS was evaluated as a "moderate positive correlation" for all pattern identifications. The average flow rate and maximum flow rate using uroflowmetry was evaluated with "moderate negative correlation" for Yang Deficiency of Kidney and Dampness-heat of Lower Energizer. Conclusion: The reliability of a pattern identification tool for benign prostatic hyperplasia was evaluated as "poor agreement beyond chance." Further research is needed.

Background : Mahuang (Ephedrae Herba, Ephedra sinica $S_{TAPE}$) has been widely used to treat respiratory disease in Asian over the past thousand years. The main ingredient of Mahuang is ephedrine, whose affects on the autonomic nervous system induce some adverse effects like vasoconstriction, hypertension, tachycardia, miosis, insomnia, dizziness, headache, etc. Although there were lots of reports about adverse effects of Mahuang, there were no clinical studies which evaluated the adverse effects of Mahuang on the autonomic nervous system by objective numerical value in the past decade. Objectives : The purpose of this report was to provide an objective assessment of state-trait anxiety that is caused by Mahuang, and to identify anxiety of Mahuang according to different Sasang constitution classifications. Methods : The study design was a double-blind randomized placebo-controlled trial. The subjects of this study were 79 adults aged between 20 to 40 who agreed to participate. Because 8 adults dropped out, a total of 71 subjects entered the study. They were allocated through randomization to a Mahuang group (N=50) and placebo group (N=21). Each group took three opaque capsules (every opaque capsule containing 2g of Mahuang or none) twice a day. To compare the state and trait anxiety before and after taking Mahuang, we checked the anxiety by using STAI-KYZ. Results : The following results were obtained. Short-term administration of Mahuang significantly increased state-anxiety, but in the placebo group, there were no significant changes in state-anxiety. In the Mahuang group except females, there was more significant increase in state-anxiety of Soeumin than Soyangin and Taeumin in the 2nd measurement. Conclusion : It is suggested that the ingestion of Mahuang can increase sympathetic activity and induce anxiety. There was a significant difference among Sasang constitution classification. Especially, the response is stronger in Soeumin than other constitutions. If we use Mahuang according to the Sasang constitution classification in clinic, we could not only minimize the anxiety but maximize the potential curative value.

Objectives: The aim of this study was to develop a standard instrument of pattern identification and evaluation for chemotherapy-induced peripheral neuropathy (CIPN).Methods: The advisory committee for this study was organized by 12 professors of traditional Korean medicine from the Korean Association of Traditional Oncology. The items and structure of the instrument were designed based on a review of previous publications. We revised the instrument in consultation with the advisory committee and received additional advice via email.Results: We divided the symptoms and signs of CIPN into four pattern identifications: wind arthralgia (風痺), cold arthralgia (寒痺), dampness arthralgia (濕痺), and arthralgia of the deficiency type (虛痺). We obtained the mean weights to reflect the standard deviations from each symptom of the four pattern identifications, which were scored on a 5-point scale by the advisor committee. After we obtained the answers to discrimination between variable symptoms (變症) and ordinary symptoms (素症) from the 12 experts, we gained the final weight from the combination of the ratio of pattern identification to the number of total answers of the advisory committee and the mean weight.Conclusions: The Instrument on Pattern Identification and Evaluation for CIPN was developed through a discussion between 12 experts. There was a limitation that the validity and reliability of this instrument have not been proven. However, the significance of this study was that it is the first Instrument on Pattern Identification and Evaluation aimed at assessing CIPN in traditional Korean medicine.

Objectives : Mahuang (Ephedra sinica), well known as an herbal medicine in the East and West, contains a relatively high percentage of ephedrine known as sympathomimetic alkaloid. We investigated the effects of Mahuang on sympathetic nervous system with heart rate variety (HRV). Time and frequency domain analysis of HRV is a noninvasive technique capable of providing information on autonomic modulation of the sinus node. Methods : We investigated 57 healthy volunteers consisting of 37 subjects in the Mahuang group and 20 subjects in the placebo group. Study form was a randomized, placebo-controlled, double-blind clinical trial. The 37 subjects in the Mahuang group took 3 Mahuang capsules (1 capsule equivalent to 2g herb Mahuang) twice a day at 10 a.m. and 2 p.,., while the 20 subjects in the placebo group took 3 placebo-capsules filled with glutinous rice powder at the same times. Mahuang medicine and placebo medicine were made into opaque capsules. We measured HRV at 3 p.m. 1 or 2 days before medication and at 3 p.m. after medication. Results : Mean-RR and SDNN of the Mahuang group significantly decreased compared with that of the placebo group, but the heart rate of the Mahuang group significantly increased compared with the placebo. HRV-Index, RMSSD and SDSD of the Mahuang group significantly decreased compared with that of the placebo group, but PNN50 of the Mahuang group significantly increased compared with placebo. Ln(TP), Ln(VLF), Ln(LF) and Ln(HF) of the Mahuang group significantly decreased compared with those of the placebo group. There were no significant differences in normalized LF, normalized HF and LF/HF ratio between the Mahuang and placebo groups. Conclusion : The results suggest that Mahuang in healthy adults tends to reduce the autonomic nervous system within the normal range.

Background : Ephedra (Ephedra sinica) has been widely used to treat respiratory disease in traditional medicine of East Asia for over a hundred years. Despite safety concerns raised by some, the use of ephedra in traditional medicine is documented over more than 1,800 years. It is well established that ephedra is one of the central medicines in Korean 'Seseng constitution' medicine. In Sasang constitution medicine, all humans can be divided into one of four types: Soeumin, Soyangin, Taeumin or Taeyangin, and each constitution type has their own typical characteristics. Accordingly, it is hypothesized that the adverse effects of ephedra differ depending on the Sasang constitution classification. Objectives : The aim of this study was to determine adverse effects of ephedra which is classified as a Taeumin herb, and to observe whether the response differs or not. according to Sasang constitution classification. Methods : The study design was a double-blind randomized controlled trial. The subjects were healthy adults 20 - 50 years old who agreed to participate in this study. They were allocated through randomization to either ephedra group (N=55) or placebo group (N=24). where ephedra extract (6 g of dried ephedra) and placebo with similar opaque capsules were given twice for one day. To compare the adverse events of ephedra according to Sasang constitution classification, we analyzed blood pressure (systolic and diastolic), pulse rate, the morning questionnaire, and patient's global assessment scale score for well known adverse events: palpitation, headache, sweating, tiredness, dyspepsia, and dry mouth. Results : After ingestion of ephedra, the pulse rate had a significant increase in all constitution types. The changes of diastolic pressure in Soeumin and the changes of pulse rate in Soeumin, Soyangin and Taeumin had a significant increase in the ephedra over the control group. In the ephedra group, the palpitation and dyspepsia score of the patients' global assessment scale had a significant increase in Soeumin, with palpitation and sweating score increasing in Soyangin. Others observations were insignificant results. Conclusion : The results of this study may confirm that the physical responses or adverse effects of herbs differ for each type of Sasang constitution. Future studies using other herbs will be required to ascertain the herbal drug reaction of Sasang constitutions.

Fisetin is a bioactive flavonol molecule and has been shown to have antioxidant potential, but its efficacy has not been fully validated. The aim of the present study was to investigate the protective efficacy of fisetin on C2C12 murine myoblastjdusts under hydrogen peroxide (H₂O₂)-induced oxidative damage. The results revealed that fisetin significantly weakened H₂O₂-induced cell viability inhibition and DNA damage while blocking reactive oxygen species (ROS) generation. Fisetin also significantly alleviated cell cycle arrest by H₂O₂ treatment through by reversing the upregulation of p21WAF1/CIP1 expression and the downregulation of cyclin A and B levels. In addition, fisetin significantly blocked apoptosis induced by H₂O₂ through increasing the Bcl-2/Bax ratio and attenuating mitochondrial damage, which was accompanied by inactivation of caspase-3 and suppression of poly(ADP-ribose) polymerase cleavage. Furthermore, fisetin-induced nuclear translocation and phosphorylation of Nrf2 were related to the increased expression and activation of heme oxygenase-1 (HO-1) in H₂O₂-stimulated C2C12 myoblasts. However, the protective efficacy of fisetin on H₂O₂-mediated cytotoxicity, including cell cycle arrest, apoptosis and mitochondrial dysfunction, were greatly offset when HO-1 activity was artificially inhibited. Therefore, our results indicate that fisetin as an Nrf2 activator effectively abrogated oxidative stress-mediated damage in C2C12 myoblasts.

Objectives: The cardio-ankle vascular index (CAVI) and ankle-brachial index (ABI) are non-invasive methods to evaluate cardiovascular disease and arteriosclerosis. This study investigated the relationship between CAVI, ABI, and factors related to arteriosclerosis. Methods: This study included 535 healthy adults who underwent health examinations in 2019. We analyzed the correlation between CAVI, ABI and clinical variables. Multiple regression analysis was performed on the independent clinical variables associated with CAVI and ABI. Results: The correlation analysis of CAVI showed that body mass index (BMI) and HDL-cholesterol (HDL-C) had a negative correlation, and the other variables had a significant positive correlation. The correlation analysis with ABI on the right side showed that age, diastolic blood pressure (DBP), gender, and LDL-cholesterol (LDL-C) had a significant positive correlation, while HDL-C had a significant negative correlation. There was no statistical significance on the left. In the multiple regression analysis, DBP, age, BMI, gender, and HDL-C were proved to be independent factors in CAVI (right) (R²=0.365); DBP, age, gender, BMI, fasting blood sugar, and total cholesterol in CAVI (left) (R²=0.357); and age, gender, DBP, and systolic blood pressure in ABI (right) (R²=0.133). There were no statistically significant factors in ABI (left). It could be inferred that smoking and drinking are determinants that play an important role in CAVI. Conclusion: CAVI showed a high correlation with gender, age, and blood pressure. A significant correlation between CAVI and serum lipid values could be observed, but this showed a low correlation coefficient. ABI showed a high correlation with age and DBP. These results support the use of CAVI and ABI as primary diagnostic devices in medical treatment.
