This study was focused on a certain clinical symptom, which could applicated by Pyeongwi-san, and the radical treatment. Pyeongwi-san is applicable to dampness retention in the spleen and stomach, accompanied by abdominal fullness, anorexia, nausea and regurgitation. Main action of Pyeongwi-san is to dry dampness, invigorate the spleen, promote the flow of gi, and regulate the stomach. The herbal remedy drying dampness like Pyeongwi-san however, is just indicatio symptomatica therefore radical treatment must be used together. Jeunginmaegchi, a medical book written by Gyeong-Myeong Jin, who was lived in Myeong dynasty. This book contains many clinical applicable symptoms and constituents derived from Pyeongwi-san. The herbal prescriptions composing Pyeongwi-san is composed of Changchul, Hubak, Jinpi, Gamcho. The major action of these herbs is drying dampness. Therefore, it shoud be seriously consider that curative therapy must eliminate the cause of endogenous dampness.

Objectives : Pyeongwi-san is widely used in Korean medicine for acute indigestion or gastrodynia. As a therapeutic agent for digestive diseases of modern people, in order to confirm the mechanism of Pyeongwi-san on digestive tract disease and the difference of therapeutic efficacy between its formulation, a comparative efficacy test was conducted on digestive tract disease animal model. Methods : For LPS enteritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san, and then intraperitoneally administered LPS one hour later to induce enteritis. After 5 hours, blood was collected and TNFα, IL-1β, IL-6 and PGE2 were confirmed by ELISA. For acute gastritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san according to the prescribed concentration, and then intraorally administered 60% ethanol and 150 mM HCl one hour later to induce acute gastritis. After 5 hours, blood was collected and TNFα,IL-6 were confirmed by ELISA. Results : In the LPS-administered enteritis animal model, Pyeongwi-san decreased TNFα, IL-1β, PGE2 and especially IL-6. Pyeongwi-san also decreased IL-6 in acute gastritis animal model. In addition, there was no significant difference in efficacy between the two formulations when compared with inflammatory markers. Conclusions : The efficacy of Pyeongwi-san was confirmed in the inflammatory markers related to digestive inflammatory diseases, and the efficay between two formulations of Pyeongwi-san was relatively similar. Further studies are needed to investigate the new applicability of Pyeongwi-san on different inflammatory diseases that have similar inflammation markers identified in this experiment.

Objectives: This study was performed to investigate the protective and treating efficacy of Pyeongwi-san, Ijin-tang, and Pyeongjin-tang extracts to the mice with gastric mucosal lesions induced from indomethacin. Methods: In order to verify protective and treating efficacy of Pyeongwi-san, Ijin-tang, and Pyeongjin-tang extracts to the mice with gastric mucosal lesions induced from indomethacin, I administered the extracts of these prescriptions to three group, and induced gastric mucosal lesion by indomethacin, and then I observed the gastric mucosal morphology of stomach, changes from stress resulting from HSP70, changes of gastro-protection (mucous barrier, COX-1). After I observed the anti-oxidant effect, and anti-inflammation effect (IKK mRNA, iNOS mRNA, COX-2 mRNA) in vitro, I induced gastric mucosal lesion by indomethacin, and administered the extracts of each prescriptions to three group, and then I observed the gastric mucosal morphology, anti-inflammation effect to mucosa (NF-${\kappa}$B, iNOS, COX-2) in vivo. Results & Conclusions: 1. Hemorrhagic erosion and damaged mucus secreting cell, positive responses to HSP70 were decreased in all the before-gastric-mucosal-lesion-induced groups, compared to non-extract administered group. The effects were good in the order of Pyeongwi-san extracts administered group, Pyeongjin-tang extracts administered group and Ijin-tang extracts administered group. 2. In all the before-gastric-mucosal-lesion-induced groups, gastro- protection functions (mucous barrier, COX-1) were significant. The effects were good in the order of Pyeongwi-san extracts administered group, Pyeongjin-tang extracts administered group and Ijin-tang extracts administered group. 3. Anti-oxidant effect was significant in Pyeongwi-san extracts, Ijin-tang extracts and Pyeongjin-tang extracts. The effects were good in the order of Pyeongjin-tang extracts, Pyeongwi-san extracts and Ijin-tang extracts. 4. The anti-inflammation effects in vitro were good in Pyeongwi-san extracts, Ijin-tang extracts and Pyeongjin-tang extracts. Especially Pyeongjin-tang extracts showed the most prominent results. Damaged mucus secreting cells and the positive reactions of NF-${\kappa}$B, iNOS, COX-2 in vivo were decreased in after-gastric-mucosal-lesion-induced groups compared to non-extract administered group. The effects were good in the order of Pyeongjin-tang extracts administered group, Pyeongwi-san extracts administered group and Ijin-tang extracts administered group. These results show that Pyeongwi-san, Ijin-tang and Pyeongjin-tang are effective on both in protecting and treating the gastric mucosal membrane. Pyeongwi-san is more effective than other prescriptions, in protecting gastric mucosal membrane, and Pyeongjin-tang is more effective in treating gastric mucosal lesion.

Objectives : The purpose of this study was to investigate the interpretation of the Pyeongwi-san(PWS) prescription in order to obtain the evidence for clinical applications. Methods and Result : We interpreted on the PWS-related contents based on 15 classic books, analyzed it according to followed categories ; origin, indication and precaution, usage, meaning of name, physiological and pathological situation of PWS, explain about each herbs. Conclusion : 1. PWS was first mentioned in the Bakjebang, its application was enhancing appetite. Application of PWS not only expanded digestive disease, infectious disease, and pain in articular, but also used to toniyfing drug. 2. Generous application method of PWS was ‘Sujunbok(水煎服)’. Pill preparation(丸劑) and decoction with salt(鹽湯劑) were also used 3. "Pyeongwi(平胃)“ in PWS means "flatten the stomach". There are some theory about methodology to "Pyeongwi (平胃)“, one is "drain the pathogen in stomach(敦阜說)”, other is "tonifying stomach's healthy qi(卑監說)“, the other is compromise theory. 4. Most medical literature related application situation of PWS to dampness(濕邪) in stomach. In Gangsulwongobangsunju, there are more detailed explain focused on metal qi(金氣), and fire qi(火氣) 5. Atractylodes japonica Koidz(蒼朮) drys dampness and fortifys the spleen, Magnolia officinalis Rehder(厚朴) eliminates dampness and treats fullness, Citrus reticulata Blanco(陳皮) moves and drains qi, Glycyrrhiza uralensis Fisch(甘草) tonify and harmonize in herbal formula

Objective : To investigate the effects of Pyeongwi-san-gamibang on atopic dermatitis, this study measured TEWL(transepidermal water loss), observed scratching behaviors and checked levels of Total IgE, IL-4, IFN-${\gamma}$ and conducted skin biopsy on NC/Nga mice with atopic dermatitis. Methods : NC/Nga mice were challenged with DNCB during 5 weeks to develop atopic dermatitis-like skin lesions. The NC/Nga mice with atopic dermatitis were divided into three groups of control group, PW-d, PW-e group. Once a day for 22 days, Pyeongwi-san-GamiBang extract with water was administered for the PW-d group and the extract with 80% ethanol was administered for PW-e group compared with saline solution for control group. During drug administration, sensitization by DNCB had lasted for three times per week. Results : 1. TEWL had no statistical difference among 3 groups. 2. The scratching behaviors had no statistical difference among 3 groups. 3. The levels of Total IgE in PW-d, PW-e group had a statistically significantly higher than that of the control group although difference between the control group and the PW-d, PW-e group were similar. 4. The level of IL-4 had no statistical difference among 3 groups. 5. The level of IFN-${\gamma}$ had no statistical difference among 3 groups. 6. As the observation of toluidine blue stained lesion, both PW-d and PW-e group had lower level of histamine releasement compared with the control group. Conclusion : Result based on these experiments, Pyeongwi-san-GamiBang on atopic dermatitis-like skin inflammation in NC/Nga mice is not effective. But, as the study showed significantly individual differece, we need to repeat these study after supplementing the object number and modified indicator of clinical severity.

Objective: This study was designed to identify and explore the pathological patterns of functional dyspepsia (FD) patients. We also evaluated the usefulness of the Pattern Identification Questionnaire by comparing it with other assessment tools for FD. Methods: We recruited 97 FD patients based on the Rome III criteria for FD diagnosis. The pathological patterns of the subjects were determined by the Pattern Identification Questionnaire. Their dyspepsia-related symptoms were assessed using the Gastrointestinal Symptom Questionnaire (GIS) and the Pyeongwi-san (Pingwei-san) Patternization Questionnaire. Depressive symptoms were evaluated with the Beck Depression Inventory (BDI) and quality of life with the Functional Dyspepsia-Related Quality of Life (FD-QoL) Questionnaire. Tongue coating was measured by the Digital Tongue Diagnosis System (DTDS). Results: The male to female ratio was 1:1.1, and the forties and fifties age groups were largest in number. The spleen deficiency and phlegm-dampness pattern was the most common pattern found among the FD patients. No significant differences in the GIS, BDI, FD-QoL, and DTDS scores were found among the five pattern types. All pattern types showed significant correlation with GIS, Pyeongwi-san Patternization Questionnaire, and FD-QoL scores. Conclusions: Pattern Identification Questionnaire can not only identify the pathological pattern types of FD patients but also evaluate the severity of their symptoms. Compared to conventional assessment tools for FD, it could enable a more dynamic evaluation of FD patients reflecting the severity of dyspeptic symptoms and the quality of life. Further studies on the Pattern Identification of FD patients are anticipated in order to improve the diagnosis and therapy for Korean FD patients.

Abstract: This retrospective study delved into the effects and safety considerations associated with the concomitant usage of hypoglycemic agents and herbal extracts, specifically Pyeongwi-san (PWS) or HyangsaPyongwi-san (HSPWS) in the context of type 2 diabetes mellitus management. Methods: The investigation involved 38 inpatients with type 2 diabetes mellitus who received PWS or HSPWS treatment at Kyung Hee University Korean Medical Hospital from January 2012 to December 2022. By investigating clinical attributes and conducting laboratory assessments, this study aimed to discern the impact of these herbal extracts on blood glucose levels, encompassing fasting blood sugar (FBS) and mean 2-hour postprandial glucose (PP2) levels. Furthermore, the safety profile of the herbal extracts was assessed by comparing liver function indicators, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and γ-glutamyl transferase (GGT), alongside kidney function markers, such as blood urea nitrogen (BUN) and creatinine (Cr). Results: Following the administration of the herbal extracts, no statistically significant alterations in FBS and mean PP2 levels emerged compared to the baseline levels. Notably, the safety evaluation revealed no significant differences in liver and kidney function parameters following herbal extract administration. Conclusion: The results of this research indicate that using PWS or HSPWS alongside hypoglycemic medications could be a beneficial additional method for addressing digestive symptoms in individuals with type 2 diabetes mellitus. Notably, this combination seems to have no negative interactions with other drugs.

The purpose of this study is to investigate the protective effects of 25 herbal formulas on acetaminophen (APAP) or D-galactosamine (D-GalN)-induced hepatotoxicity in primary rat hepatocytes. Cell viability was measured using by Cell Counting Kit-8. 15 kinds of herbal formulas significantly reversed the cell viabilities of D-GalN-treated rat hepatocytes compared with D-GalN alone (p<0.05). In particular, 9 herbal formulas (Bangpungtongseong-san, Bojungikgi-tang, Galgeun-tang, Gumiganghwal-tang, Guibi-tang, Sagunja-tang, Samsoeum, Pyeongwi-san and Yijin-tang) showed the potent protective effects. However, 8 herbal formula exerted weak protective effects and 2 herbal formula did not exert effects on hepatotoxicity by D-GalN. On APAP-induced hepatotoxicity, 7 kinds of herbal formulas increased the viabilities of hepatocytes compare with APAP alone (p<0.05). These results could be provide a valuable information for the future in vivo or clinical studies to predict the hepatoprotective effects of herbal formulas.
