The purpose of this study was to review the herbal medications of asthma through clinical studies in Korea and to be utilized in the treatment of asthma and in other clinical studies. All clinical researches about asthma published up to 13th February 2018 were found in two domestic electric databases, Oriental Medicine Advanced Searching Integrated System(OASIS) and National Discovery for Science Library(NDSL). Twenty-seven articles were selected and of these, there were 14 articles of before and after studies(BAS), 8 of case series(CS), 4 of case reports(CR) and 1 of the randomized controlled trial(RCT). The most frequently used prescription was "Cheongsangboha-tang(淸上補下湯)". There were various TCM patterns, and Tae-Eum-In(太陰人) was the most common Sasang constitution(四象體質). Frequently used evaluations to assess treatment effects were lung function tests such as Forced expiratory volume at one second (FEV1) and Quality of Life Questionnaire for Adult Korean Asthmatics(QLQAKA) questionnaire responses. We have found that herbal medicine treatment can be an effective treatment to improve the symptoms and the quality of life of asthmatic patients. But we consider that large-scale systematically designed clinical researches are needed additionally.

The purpose of this study is to find out the direction of development of the expert diagnosis system by questioning student satisfaction after practicing Oriental Diagnosis System (ODS). A questionnaire survey was conducted for 73 students who attended Pusan National University Graduate School of Korean Medicine and conducted clinical practice from the second semester of 17 years to the first semester of 18 years. The questionnaire survey consisted of 6 questions about the satisfaction of current expert system and 5 questions about supplementation and addition. As a result of the questionnaire analysis, the question about the necessity of the expert diagnosis system and the benefit of clinical practice using the expert diagnosis system indicated high positive response rate. On the other hand, there is a difference in the results of the dialysis before and after using the expert diagnosis system. So, It seems that the reliability of the results of the expert diagnosis system is still low. The results of the questionnaire indicate that the need for expert diagnosis system is beneficial, but it is necessary to supplement the current system in order to improve clinical utility in the future.

This study was conducted to investigate the cognitive improvement and memory recovery effects of Korean and Chinese Crataegus pinnatifida ethanolic extracts on scopolamine-induced memory impairment in mice. In vivo studies were carried out with mice treated with Korean Crataegus pinnatifida extracts (KCF) and Chinese Crataegus pinnatifida extracts (CCF) in doses of 5 and 50 mg/kg (p.o.) and scopolamine was injected 30 min before the behavioral testing. Antioxidant activity was assessed by 2,2-diphenyl-1-picryl hydrazyl (DPPH) assay and 2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay, and acetylcholinesterase inhibition by Ellman's modified method. The chlorogenic acid and hyperoside as marker compounds of KCF and CCF was quantified by ultra-performance liquid chromatography analysis (UPLC). Results showed that KCF was more contained high content of chlorogenic acid and hyperoside than CCF. In addition, KCF was more exerted free radical (DPPH and ABTS) scavenging activity and blocked AChE activity than CCF. In vivo studies also showed that KCF administration has a further improved the memory of scopolamine-treated mice than CCF in Y-maze test, passive avoidance test and Morris water maze test. These results revealed that KCF more prevents scopolamine-induced memory impairments through antioxidant and acethylcholinesterase inhibition effect compared CCF.

This paper confirmed the effect of Baekho-tang(白虎湯) on psoriasis patient diagnosed with Yangmyung-Yeoljeung(陽明熱證). We treated patients with psoriasis classified as Yangmyung-Yeoljeung(陽明熱證) according to Shanghanlun(傷寒論) with Baekho-tang(白虎湯). Two patients was treated with Baekho-tang(白虎湯) for 18 days and 75 days, respectively. Baekho-tang(白虎湯) used in the treatment consisted of Gypsum Fibrosum 16g, Oryza semen 12.5g, Anemarrhena Rhizoma 6g and Glycyrrhizae Radix 2g. The severity of psoriasis was evaluated by PASI(psoriasis area severity index) and pictures. Also we checked the change in Pruritus by VAS(visual analogue scale). After the Baekho-tang(白虎湯) treatment, the PASI of 2 patients decreased from 13 to 2.8 and from 10.8 to 0.8 respectively. In addition, VAS of 2 patients diminished from 10 to 3 and from 8 to 1 respectively. Moreover, no side effects were observed. We received effective results by giving Baekho-tang to Psoriasis patients with sweaty, dry mouth, and heating sensation. Anti-inflammatory, antipyretic effects and immunomodulatory functions of Baekho-tang(白虎湯) could lead to improvement of psoriasis.

The purpose of this study was to investigate the antioxidant and hangover cure effects of compound prescription containing Phyllanthus emblica and Azadirachta Indica leaf extract (CP). In vitro experiments, HepG2 cells were induced oxidative stress by hydrogen peroxide (H2O2) and treated with CP at 50, 100, 200 ㎍/㎖ concentration. Antioxidant enzyme (superoxide dismutase (SOD), catalse (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) activity and glutathione (GSH) content were decreased by hydrogen peroxide-induced oxidative stress, but CP was increased that. In vivo experiments, experiment rats were orally administered alcohol 3 g/kg and, after 30 min administered CP 200 mg/kg. After 1 and 3 h of alcohol administration, blood was collected from the tail vein, while after 5 h, blood was collected from the heart. CP modulates alcohol dehydrogenase (ADH) and acetaldehyde level, thereby decreased alcohol level in serum. Also, CP decreased the levels of aspartate aminotransferase (AST) and alkaline phosphatase (ALP). These results suggest that CP has antioxidant effects and alleviates alcohol hangover symptoms.

The purpose of this study was to investigate the effects of natural herb mixture containing Laminaria japonica Areschoung (LAM) on fine dust-induced bronchitis in mice. Laminaria japonica Areschoung is main content of LAM, which is including fucoidan. Fucoidan extracted from phaophyta is known to prevent bronchitis and to defend against bacteria and virus infection. In this study, we experienced the effect of LAM on bronchitis and investigated gene expressions (e.g ; IL-8, COX-2, MCP-1) and bio-markers (e.g ; IL-8, PGE2, MUC5AC) associated with bronchitis by using A549 cells. Also, we investigated whether LAM can suppress the bronchitis in fine dust-induced animal models. We injected fine dust (50 ㎕) twice as INT (Intra-Nasal-Trachea) method. Then LAM (200 mg/kg and 400 mg/kg) were oral administered for 14 days. We analyzed the number of immune cells, immunoglobulin E, bio-markers level associated with bronchitis. LAM significantly decreased bio-marker (IL-1β, IL-6, IL-8, TNF-α, Histamine, PGE2), immune cells (white blood cell, neutrophil, lymphocyte, monocyte), and immunoglobulin E, that are increased by fine dust. Taken together, this study suggest that LAM can be used as effective herbal extract for bronchitis.

Since Traditional Korean medicine (TKM) doctors use various knowledge systems during treatment, diagnosis results may differ for each TKM doctor. However, it is difficult to explain all the reasons for the diagnosis because TKM doctors use both explicit and implicit knowledge. In this study, an upgraded random forest (RF)-based evaluation tool was proposed to extract clinical knowledge of TKM doctors. Also, it was confirmed to what extent the professor's clinical knowledge was delivered to the trainees by using the evaluation tool. The data used to construct the evaluation tool were targeted at 106 people who visited the Sasang Constitutional Department at Kyung Hee University Korean Medicine Hospital at Gangdong. For explicit knowledge extraction, four TKM doctors were asked to express the importance of symptoms as scores. In addition, for implicit knowledge extraction, importance score was confirmed in the RF model that learned the patient's symptoms and the TKM doctor's constitutional determination results. In order to confirm the delivery of clinical knowledge, the similarity of symptoms that professors and trainees consider important when discriminating constitution was calculated using the Jaccard coefficient. As a result of the study, our proposed tool was able to successfully evaluate the clinical knowledge of TKM doctors. Also, it was confirmed that the professor's clinical knowledge was delivered to the trainee. Our tool can be used in various fields such as providing feedback on treatment, education of training TKM doctors, and development of AI in TKM.

We investigated the effects of gambigyeongsinhwan(GGH)(4) on body weight and non-alcoholic fatty liver disease(NAFLD) examined whether blood total cholesterol, LDL-cholesterol, free fatty acid and triglyceride levels and hepatic lipid accumulation are inhibited by it in high fat diet-fed obese male mice. 8 weeks old, high fat diet-fed obese male mice were divided into 5 groups: C57BL/6N normal, control, GGH(4)-1, GGH(4)-2 and GGH(4)-3. After mice were treated with GGH(4) for 8 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma ALT, leptin and lipid levels. We also did histological analysis for liver and fat on the mice. Compared with controls, GGH(4)-treated mice had lower body weight gain and adipose tissue weight, the magnitudes of which were prominent in GGH(4)-2. Compared with controls, GGH(4)-treated mice had lower feeding efficiency ratio and blood leptin level, the magnitudes of which was prominent in GGH(4)-2. Compared with controls, GGH(4)-treated mice had lower blood plasma total cholesterol, LDL-cholesterol, free fatty acid and triglyceride levels. Compared with controls, GGH(4)-2 treated mice had lower blood plasma ALT concentration. Consistent with their effects on body weight gain, the size of adipocytes were significantly decreased by GGH(4), whereas the adipocyte number per unit area was significantly increased, suggesting that GGH(4) decreased the number of large adipocytes. Hepatic lipid accumulation was decreased by GGH(4). In conclusion, these results suggest that GGH(4) exhibits anti-obesity effects through the modulation of feeding efficiency ratio and plasma obesity parameters. Moreover, it seems that GGH(4) also contributes to improve NAFLD through the regulation of plasma ALT and hepatic triglyceride accumulation.
