Objectives : This study was carried out to investigate the acute toxicity and safety of $Leejung$-$tang$($Lizhong$-$tang$) and fermented $Leejung$-$tang$($Lizhong$-$tang$) extract. Methods : To evaluate their acute toxicity and safety, 0(control group), 1250, 2500 and 5000 mg/kg of $Leejung$-$tang$($Lizhong$-$tang$) and fermented $Leejung$-$tang$($Lizhong$-$tang$) extracts were orally administered to 35 male and 35 female ICR mice. After a single administration, we observed survival rates, general toxicity, changes of body weight, and autopsy. Results : Compared with the control group, we could not find any toxic alteration in any of treated groups (1250, 2500 and 5000 mg/kg). Conclusions : $LD_{50}$ of $Leejung$-$tang$($Lizhong$-$tang$) and fermented $Leejung$-$tang$($Lizhong$-$tang$) were over 5000 mg/kg and it is very safe to ICR mice.

We had one female ALS patient. The patient was diagnosed with ALS by EMG and Symptoms. We diagnosed the patient as Jinshang(筋傷) and Pishenyangxu(脾腎陽虛). We gave Shaoyaogancao-tang jiami(芍藥甘草湯加味) and Sijunzi-tang he Lizhong-tang jiami(四君子合理中湯加味) based on the differentiation of symtoms. We report the changes of the ALS patient's disphagia, lalopathy, and hypotonia after two months treatment with Riluzole and oriental medical treatment.

Objective : Stroke patients tend to take antibiotics due to infection resulting from complication. One of many side effects from using antibiotics is diarrhea, which infact causes anaerobic organism dysfunction resulting Pseudo-Membranous Colitis (P.M.C). To treat P.M.C, antibiotics and antibacterial agents are usually used. But they may cause other side effects, therefore extreme caution must be taken. Methods : We treated an antibiotic induced P.M.C patient who diagnosed by sigmoid scopy with only Yijoong-tang (Lizhong-tang) without antibiotics and observed patients stool aspects. Results and Conclusion : Patiensts symptom was improved after 7days, and we can see the improvement by follow-up sigmoid scopy. This case may give us a possibility of that oriental medical treatments as complementary and alternative medicine to standard antibiotic treatment.

Dynamics of the electric system for the toroidal drive under mechanical disturbance is presented. Using the method of perturbation, free vibrations of the electric system under mechanical disturbance are studied. The forced responses of the electric system to voltage excitation under mechanical disturbance are also presented. We show that as the time grows, the resonance vibration caused by voltage excitation still exists and the vibrations caused by mechanical disturbance are enlarged. The coupled resonance vibration caused by mechanical disturbance and voltage excitation is discussed. The conditions of the occurrence of coupled resonance are studied.

Objectives : Leejung-tang (Lizhong-tang) has been used for treatment of gastrointestinal disorders in Korea. In this study, we performed quantification analysis of five marker components, liquiritin, ginsenoside Rb1, ginsenoside Rg1, glycyrrhizin, and 6-gingerol in Leejung-tang using a ultra performance liquid chromatography- electrospray ionization-mass spectrometer (UPLC-ESI-MS). In addition, we evaluated antioxidant activity of Leejung- tang. Methods : The column for separation of five constituents used a UPLC BEH C18 ($100{\times}2.1mm$, $1.7{\mu}m$) maintained at $45^{\circ}C$. The mobile phase consisted of two solvent systems, 0.1% (v/v) formic acid in H2O (A) and CH3CN (B) by gradient flow. The flow rate was 0.3 mL/min with detection at mass spectrometer. The antioxidative activities conduct an experiment on 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities of Leejung-tang. Results : Calibration curves of five marker compounds were acquired with r2 values > 0.99. The amount of the five compounds in Leejung-tang were 0.07 - 0.84 mg/g. The concentration required for 50% reduction (RC50) against ABTS radical was 119.02 ug/mL. In addition, the scavenging against DPPH radical of Leejung-tang was 11.4%, 14.5%, 19.8%, 29.6%, and 49.2% at 25 ug/mL, $50{\mu}g/mL$, $100{\mu}g/mL$, $200{\mu}g/mL$, and $400{\mu}g/mL$, respectively. Conclusions : The established LC-MS/MS method will be helpful to improve quality control of Leejung-tang. In addition, Leejung-tang is a potential antioxidant therapeutic agent.

Objective: This study assessed the effectiveness of using Yijung-tang to treat chronic gastritis through a systematic review and meta-analysis of randomized controlled trials (RCTs). Methods: The search was conducted using keywords such as "gastritis", "Lizhong", "Yijung", and "Chronic gastritis" on July 31, 2023. A meta-analysis was conducted according to outcome measurements, such as total effective rate (TER), Traditional chinese medicine symptom score (TSS), gastric hormones, and symptom relief time, using the Review Manager website. Results: A total of 11 RCT studies were selected. The treatment group (Yijung-tang-gagam or Yijung-tang-gagam+Western medicine) showed significant improvement effects in terms of TER, TSS, serum gastrointestinal hormones (motilin (MTL), gastrin (GAS), and somatostatin (SS)), and symptom relief time compared to the control group (Western medicine). TER-RR : 1.20, 95% CI : 1.11 to 1.30, P≤0.00001, RR : 1.21, 95% CI : 1.14 to 1.28, P≤0.00001; MTL-MD : 35.99, 95% CI : 30.79 to 41.20, P≤0.00001); GAS-MD : 103.33, 95% CI : 97.62 to 109.04, P≤0.00001); SS : MD : -37.19, 95% CI : -41.75 to -32.64, P≤0.00001; symptom relief time (nausea)-MD : -1.96, 95% CI : -2.47 to -1.45, P≤0.00001; symptom relief time (colic)-MD : -1.75, 95% CI : -2.31 to -1.18, P≤0.00001. Conclusion: This study suggests that Yijung-tang is effective against chronic gastritis. However, the number of studies was insufficient, and the diagnosis and evaluation criteria were not standardized. Furthermore, because of the low quality of the included studies, more clinical studies need to be conducted to increase the possibility of clinical use.

Change detection of remote sensing images is a profound challenge in the field of remote sensing image analysis. This paper proposes a novel change detection method for bitemporal remote sensing images based on feature fusion and fuzzy c-means (FCM). Different from the state-of-the-art methods that mainly utilize a single image feature for difference image construction, the proposed method investigates the fusion of multiple image features for the task. The subsequent problem is regarded as the difference image classification problem, where a modified fuzzy c-means approach is proposed to analyze the difference image. The proposed method has been validated on real bitemporal remote sensing data sets. Experimental results confirmed the effectiveness of the proposed method.
