Objectives : This study used a network pharmacology approach to elucidate the efficacy and molecular mechanisms of Daehwangmokdanpitang (DHMDPT) on Psoriasis. Methods : Using OASIS databases and PubChem database, compounds of DHMDPT and their target genes were collected. The putative target genes of DHMDPT and known target genes of psoriasis were compared and found the correlation. Then, the network was constructed using Cytoscape 3.10.1. The key target genes were screened by Analyzer network and their functional enrichment analysis was conducted based on the Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) Pathways to predict the mechanisms. Results : The result showed that total 30 compounds and 439 related genes were gathered from DHMDPT. 264 genes were interacted with psoriasis gene set, suggesting that the effects of DHMDPT are closely related to psoriasis. Based on GO enrichment analysis and KEGG pathways, 'Binding', 'Cytokine Activity', 'Receptor Ligand Activity' 'HIF-1 signaling pathway', 'IL-17 signaling pathway', 'Toll-like receptor signaling pathway', and 'TNF signaling pathway' were predicted as functional pathways of 16 key target genes of DHMDPT on psoriasis. Among the target genes, IL6, IL1B, TNF, AKT1 showed high correlation with the results of KEGG pathways. Additionally, Emodin, Acetovanillone, Gallic acid, and Ferulic acid showed a high relevance with key genes and their mechanisms. Conclusion : Through a network pharmacological method, DHMDPT was predicted to have high relevance with psoriasis. This study could be used as a basis for studying therapeutic effects of DHMDPT on psoriasis.

Objectives: Psoriasis is a common chronic inflammatory skin disease characterized by keratinocyte hyperproliferation and an excessive inflammatory response. Agents that can attenuate keratinocyte hyperproliferation and excessive inflammatory responses are considered potentially useful for the treatment of psoriasis. Daehwangmokdanpitang (DHMDPT) exhibits a broad range of bioactivities, including anti-proliferative and anti-inflammatory effects. This study aims to evaluate the anti-psoriatic potential of DHMDPT in vitro. Methods: HaCaT keratinocytes were stimulated with a mixture of IL-17A, IL-22, oncostatin M, IL-1α, and TNF-α (M5) to establish an in vitro psoriatic keratinocyte model. Cell viability was measured using the MTT assay. Quantitative real-time PCR (qRT-PCR) was performed to measure the mRNA levels of the hyperproliferative marker gene keratin 6 (KRT6) and inflammatory factors such as IL-6, TNF-α, and IL-23A. Additionally, chemokines including CCL5, CCL2, CCL20, and CXCL1 were measured by qRT-PCR. Results: DHMDPT attenuated M5-induced hyperproliferation, as indicated by a reduction in KRT6 expression in HaCaT keratinocytes. M5 stimulation significantly upregulated the mRNA levels of IL-6, TNF-α, and IL-23A. However, DHMDPT treatment attenuated the upregulation of IL-6 but not TNF-α or IL-23A. Additionally, DHMDPT inhibited the expression of CCL5, CCL2, and CXCL1, but not CCL20. Conclusion: DHMDPT effectively attenuated the M5-induced proliferation and inflammatory response in HaCaT keratinocytes. Therefore, DHMDPT could be an attractive candidate for future development as an anti-psoriatic agent.

Objectives : In this study, we investigated the effects of Daehwangmokdanpitang-gagambang(DMG) on treatment for cholecystokinin-octapeptide(CCK)-induced acute pancreatitis(AP) in rats. Methods : Male Wistar rats weighing 200 to 250 g were divided into three groups. The first was normal untreated group, the second was in treatment with DMG group; DMG was administered orally, followed by 75 ${\mu}g/kg$ CCK subcutaneously three times, after 1, 3 and 5 h. This whole procedure was repeated for 5 days. The third was in treatment with saline group, the protocol was the same as in treatment group with DMG. We determined the pancreatic weight/body weight ratio, the levels of pancreatic HSP60, HSP72, ERK, p38 MAPK and the secretion of pro-inflammatory cytokines. Repeated CCK treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. Results : DMG was significantly decreased the pancreatic weight/body weight ratio in CCKinduced AP and DMG increased HSP60 and HSP72 compared with CCK-induced AP. DMG suppressed ERK and p38 MAPK activation. Additionally, the secretion of $IL-1{\beta}$ and $TNF-{\alpha}$ and the levels of amylase and lipase were lower than that saline. Conclusions : DMG has an effect to treatment for CCK-induced AP.
