Objectives : The aim of this study was to evaluate the single oral dose toxicity and safety of Bojungikgi-tang (Buzhongyiqi-tang) and fermented Bojungikgi-tang (Buzhongyiqi-tang) extracts in male and female ICR mice. Methods : In the single oral dose toxicity study, non-fermented and fermented Bojungikgi-tang (Buzhongyiqi-tang) were administered to male and female ICR mice as an oral dose of 1250, 2500 and 5000 mg/kg. Changes of body weights, general behaviors, adverse effects and mortality were determined throughout the experimental period. Hematological parameters, serum chemistry, organ weights and necropsy findings were evaluated at the end of the experiment. Results : There was no mortality or sign of toxicity in the single oral dose toxicity study. There were also no significant differences in body weights, organ weights, and hematological parameters, serum chemistry values between treatment and control groups. Conclusions : The results obtained in this study suggest that the 50% lethal dose of fermented Bojungikgi-tang (Buzhongyiqi -tang) in both female and male mice can be considered as well over 5,000 mg/kg, so these medicines can be safe in clinics.

Objectives: Metabolic syndrome is defined by a cluster of major cardiovascular risk factors: obesity, insulin resistance, dyslipidemia, and arterial hypertension. Several members of a large family of nonselective cation entry channels, e.g., transient receptor potential vanilloid 4 (TRPV4) channels have been associated with the development of dyslipidemia and hypertension. The purpose of this study was to investigate the effects of Leejung-tang (Lizhong-tang), Rikkunshito, and Bojungikgi-tang (Buzhongyiqi-tang) on TRPV4 channel. Methods: Human embryonic kidney 293 cells stably transfected with the TRPV4 expression vectors were maintained in Dulbecco's modified Eagle's medium supplemented with 10% fetal bovine serum, 1% penicillin/streptomycin, $5{\mu}g/mL$ blasticidin, and 0.4 mg/mL zeocin in a humidified 20% $O_2/10%$ $CO_2$ atmosphere at $37^{\circ}C$. Whole-cell patch clamp recordings were obtained using an Axopatch 700B amplifier and pClamp v.10.4 software (Molecular Devices, San Jose, CA, USA), and signals were digitalized at 5 kHz using Digidata 1422A. Results: Leejung-tang and Rikkunshito (10, 30 and 50 mg/mL) had no effects on the TRPV4 whole-cell currents at dose dependent manner. However, Bojungikgi-tang (10, 30, and 50 mg/mL) inhibited the TRPV4 whole-cell currents in a dose dependent manner and the half maximal inhibitory concentration (IC50) of Bojungikgi-tang was 18.2 mg/mL. Conclusions: These results suggest that Bojungikgi-tang plays an important roles to inhibit the TRPV4 channel, suggesting that Bojungikgi-tang is considered one of the candidate agents for the treatment of metabolic syndrome such as dyslipidemia and hypertension.

Rectal prolapse is a condition where the rectal wall protrudes outside the anus. While it is a rare condition, it can cause discomfort for patients due to the protrusion of the rectal structure, discharge of mucus and blood, fecal incontinence, constipation, and other inconveniences. In this review, we analyzed a randomized controlled trial (RCT) study that used the herbal medicine Bojungikgi-tang(Buzhongyiqi-tang) as a complementary therapy to improve the weaknesses and side effects of the standard treatment, surgical therapy, for rectal prolapse. The analysis included 12 RCT studies, and in all studies, the prescription involved the use of Astragali Radix at the highest dosage. Among the 11 studies that evaluated efficacy, 7 studies showed a significant effect compared to the control group. In all 3 studies that evaluating recurrence rates and all 5 studies investigating complications after surgery, the experimental group showed significant effects. Based on these findings, this study could be considered as a foundational evidence for the application of bojungikgi-tang(Buzhongyiqi-tang) in clinical practice in Korean medicine for patients with rectal prolapse. It could also serve as foundational data for future research.

Objectives: This study was to evaluate the effectiveness and safety of Bojungikgi-tang for lung cancer patients with anorexia. Methods: This was a single-arm, open-label, and single-center trial, and suitable participants took Bojungikgi-tang (Buzhongyiqi-tang in Chinese, Hochuekki-to in Japanese) three times a day before or between meals for six weeks (42 days). After registration of clinical trials (visit 2), they visited the hospital every three weeks (visits 3 and 4) and measured or tested the effectiveness or safety evaluation variables to analyze the results. The primary outcome was the anorexia/cachexia subscale (A/CS) of functional assessment of anorexia/cachexia therapy (FAACT) score. Results: Seventeen lung cancer patients were included in the intention-to-treat (ITT) analysis. Lung cancer patients had higher A/CS of FAACT scores after six weeks of Bojungikgi-tang administration compared to that at the baseline. This was not significant four lung cancer (p=0.1668). In the secondary outcomes, the visual analog scale (VAS) score of anorexia decreased significantly (p=0.0009), and the CD4/CD8 ratio (p=0.0396) and CD4 levels (p=0.0345) significantly increased after six weeks of treatment. No serious adverse events were reported with Bojungikgi-tang in lung cancer patients. Conclusions: Bojungikgi-tang can be an effective and safe treatment for anorexia in lung cancer patients undergoing chemotherapy.

Bojungikgi-tang has been widely used for enhancement of physical fitness in Korea. The convenient, simple, and accurate high-performance liquid chromatography (HPLC) method was established for simultaneous determination of four marker compounds, liquiritin, nodakenin, hesperidin, and glycyrrhizin in Bojungikgi-tang (Buzhongyiqi-tang in Chinese, Hochuekkito in Japanese), a traditional Korean herbal prescription. The column for optimizing HPLC separation was used a Gemini $C_{18}$ column at column oven temperature of $40^{\circ}C$ with 1.0% (v/v) aqueous acetic acid (A) and 1.0% (v/v) acetic acid in acetonitirle (B) by gradient flow. The flow rate was 1.0 ml/min and the detector was a photodiode array (PDA) set at 254 nm, 280 nm, and 335 nm. Calibration curves of four components were acquired with $r^2$ values ${\geq}0.9999$. The recoveries were found to range 92.11~105.68% with relative standard deviations (RSDs, %) value less than 2.50%. The RSD values of intraand inter-day precision were 0.07~2.50% and 0.16~1.99%, respectively. The contents of liquiritin, nodakenin, hesperidin and glycyrrhizin in Bojungikgi-tang were 3.85~3.92 mg/g, 2.27~2.32 mg/g, 4.14~4.19 mg/g, and 3.39~3.45 mg/g, respectively. The established simultaneous analysis method will be effective for quality control of Bojungikgi-tang.

Objectives: This study investigates the effects and safety of Bojungikgi-tang for stress urinary incontinence by systemic review and meta-analysis of randomized controlled trials (RCTs). Methods: RCTs were selected from articles published until December 2019 in seven domestic and foreign databases. The quality of the literature was evaluated using Cochrane's risk of bias (RoB) tool, and RevMan 5.3 was used to synthesize the results. Results: A total of 694 patients with stress urinary incontinence participated in eight RCTs. Meta-analysis showed that the total effective rate of treatment that combines pelvic floor muscle training (PFMT) and Bojungikgi-tang was significantly higher than that of PFMT alone. The volume of urine leakage per hour after the combined treatment was significantly lower than that of PFMT alone. The International Consultation on Insurance Questionnaire-Short Form (ICIQ-SF) scores from combining PFMT and Bojungikgi-tang were significantly lower than those for PFMT alone. Conclusion: This study suggests that Western medical treatment combined with Bojungikgi-tang for urinary incontinence from stress might be more effective in improving symptoms than conventional Western medical treatment alone. However, the number of studies included in the meta-analysis was insufficient, and the quality of the selected literature was generally low. Therefore, high-quality clinical studies on herbal medicine treatment for urinary incontinence would be required in the future.

Hyperhidrosis is a condition characterized by excessive sweating. It can be generalized or focal. Generalized hyperhidrosis involves the entire body and is usually part of an underlying condition, most often an infectious, endocrine or neurologic disorder. Focal hyperhidrosis is idiopathic, occurring in otherwise healthy people. The condition carries a substantial psychological and social burden, since it interferes with daily activities. We treated two male patients who had hyperhidrosis on the head. In the point of Differentiation of Syndrom(辨證), these subjects were diagnosed as Bi-Wi-Gi-Her (Pi-Wei-Qi-Xu 脾胃氣虛) and was administered revised Bojungikgi-tang (reserved Buzhongyiqi-tang, 補中益氣湯加味方). All of two cases had anorexia, dyspepsia, fatigue. After treatment hyperhidosis and other symptoms improved.

Objectives: To identify the current status of Korean medical practice pattern, diagnosis and treatment of dementia through recognition survey, and to use it as a preliminary data for various dementia research. Methods: Questionnaires were developed through expert meetings. The disease was defined as dementia and mild cognitive impairment, and areas were designated to practice pattern, diagnosis and treatment. From December 18, 2016-January 18, 2017, 221 respondents, including 36 neuropsychiatrists of Korean Medicine and 185 general physicians (including other medical specialists) were included. Results: 1. In both groups, the most commonly used KCD (Korean standard classification of disease and cause of death) were in the order of Unspecified Alzheimer's Dementia (F00.9), Mild Cognitive Impairment (F06.7), and Unspecified Dementia (F03). 2. The most commonly used pattern identification were zang-fu and qi-blood-yin-yang in both groups. 3. Diagnostic evaluation tools were mainly conducted by MMSE, radiologic examination, K-DRS, GDS and CDR in both groups. 4. Both groups reported using acupuncture and herbal medicine mainly. 5. In both groups, the acupuncture method was used extensively in the order of Body, Scalp, and Sa-Am. 6. Neuropsychiatrists used a variety of herbal medicines such as Wonjiseokchangpo-san (Yuanzhushichangpu-san), Yukmijihwang-tang (Liuweidihuang-tang), Palmijihwang-won (Baweidihuang-won), Sunghyangjungki-san (Xingxiang Zhengqi-san) and Ondam-tanggami (Wendan-tangjiawei). General physicians used a variety of herbal medicines such as Ondam-tanggami (Wendan-tangjiawei), Bojungikgi-tang (Buzhongyiqi-tang), Yukmijihwang-tang (Liuweidihuang-tang). 7. Neuropsychiatrists used a variety of Korean herbal preparation products (benefit and non-benefit) such as Ekgan-sangajinpibanha (Yigan-sanjiachenpibanxia), Yukmijihwang-tang (Liuweidihuang-tang), Jodeung-san (houteng-san), Palmijihwang-won (Baweidihuang-won). General physicians used a variety of Korean herbal preparation products such as Bojungikgi-tang (Buzhongyiqi-tang), Banhabaegchulcheonma-tang (banxiabaizhutianma-tang), Yukmijihwang-tang (Liuweidihuang-tang), Ekgan-sangajinpibanha (Yigan-sanjiachenpibanxia), Palmijihwang-won (Baweidihuang-won). Conclusions: By confirming awareness of Korean medical doctors treating dementia in clinical fields and understanding differences between neuropsychiatrists of Korean medicine and general physicians, it can be used to understand guideline users' needs and confirm clinical questions during development of future clinical practice guidelines for dementia.
