It has been investigated about aging theory. However, aging mechanism still remains to be unknown. Aging and aging related diseases might be due to oxidative damage and these were modifiable by genetic and environmental factors. For designing an optimal medical treatment and countermeasure against aging and aging related disease, it is necessary to understand the aging mechanism. Acetylcholine(Ach) plays an important role in memory. If someone doesn't have enough Ach, he has a tendency to catch a Alzheimer's disease. Corydalis tuber has been clinically used to treat heart disease, gastrointestinal disease and other diseases including endocrine disease in Oriental medicine. The purpose of this article is to investigate the inhibitory effect on Acetylcholinesterase and scavenging effects on NO, DPPH of Corydalis tuber Acua-acupuncture solution(CTAS). The results are summerised as follows; 1. There is a significant inhibitory effect of $0.01mg/m{\ell}$ CTAS group at 20, 30, 60 minutes and $0.1mg/m{\ell}$ CTAS group at 10, 20, 30, 60 minutes on AchE. 2. There is no significant scavenging effect of CTAS on NO. 3. There is a significant scavenging effect of $0.1mg/m{\ell}$ and $0.01mg/m{\ell}$ CTAS group at 10 minutes but there is no significant scavenging effect at 20, 30, 60 minutes on DPPH. There is a significant scavenging effect of $1mg/m{\ell}$ CTAS group at 10, 20, 30, 60 minutes on DPPH.

Objectives: Primary dysmenorrhea (PD) is defined as abdominal pain during menstruation period in the absence of an identifiable pathological lesion. Corydalis tuber (CT) is an herbal medicine that has an excellent effect in relieving pain and convulsions. The purpose of this study is to observe the effect of Corydalis tuber aqueous extracts (CTe) on primary dysmenorrhea. Methods: The rats were injected with estradiol benzoate subcutaneously for 10 days (2.5 mg/kg on the first and 10th days, and 1 mg/kg from the 2~9th day). Oxytocin 1 U/kg was treated by peritoneal injection 1 hour after the last 10th injection of estradiol benzoate. CTe 400, 200 and 100 mg/kg were administered orally, once a day for 10 days at 30 minutes after each estradiol benzoate treatment. The results of CTe were compared to those of IND 5 mg/kg orally treated rats. Results: As results of estradiol benzoate and oxytocin administration, noticeable decreases of body weights and gains, uterus weights were observed with congestion and enlargement of the uterus at gross inspections, and increases of abdominal writhing responses, uterus MDA levels, GSH contents, SOD and CAT activities. However, these oxidative stress mediated PD signs were dose-dependently decreased by 10 consecutive days of oral administration of three different doses of CTe 400, 200 and 100 mg/kg as comparable to those of IND 5 mg/kg in CTe 200 mg/kg. Conclusions: CTe had a significant improvement effect on primary dysmenorrhea in the PD rat model induced by estrogen benzoate and oxytocin.

In this study, we examined the antinociceptive effect of Cyperi rhizoma (CR) and Corydalis tuber (CT) extracts using a chronic constriction injury-induced neuropathic pain rat model. After the ligation of sciatic nerve, neuropathic pain behavior such as mechanical allodynia and thermal hyperalgesia were rapidly induced and maintained for 1 month. Repeated treatment of CR or CT (per oral, 10 or 30 mg/kg, twice a day) was performed either in induction (day 0~5) or maintenance (day 14~19) period of neuropathic pain state. Treatment of CR or CT at doses of 30 mg/kg in the induction and maintenance periods significantly decreased the nerve injury-induced mechanical allodynia. In addition, CR and CT at doses of 10 or 30 mg/kg alleviated thermal heat hyperalgesia when they were treated in the maintenance period. Finally, CR or CT (30 mg/kg) treated during the induction period remarkably reduced the nerve injury-induced phosphorylation of NMDA receptor NR1 subunit (pNR1) in the spinal dorsal horn. Results of this study suggest that extracts from CR and CT may be useful to alleviate neuropathic pain.

Objectives : The purpose of this study was to investigate the molecular targets and pathways of anti-inflammatory effects of Jakyakgamchotang with corydalis tuber (JC) using network pharmacology. Methods : The compounds in constituent herbal medicines of JC were searched in TCM systems pharmacology (TCMSP). Target gene informations of the components were collected using chemical-target interactions database provided by Pubchem. Afterwards, network analysis between compounds and inflammation-related target genes was performed using cytoscape. Go enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed on inflammation-related targets using DAVID database. Results : 70 active compounds related to inflammation were identified, and 295 target genes related to the anti-inflammatory activity of the compound of JC were identified. In the Go biological process DB and KEGG pathway DB, "inflammatory response", "cellular response to lipopolysaccharide", "positive regulation of interleukin-6 production", and "positive regulation of protein kinase B. signaling", "positive regulation of ERK1 and ERK2 cascade", "positive regulation of I-kappaB kinase/NF-kappaB signaling", "negative regulation of apoptotic process", and "PI3K-Akt signaling pathway" were found to be mechanisms related to the anti-inflammatory effects related to the target genes of JC. The main compounds predicted to be involved in the anti-inflammatory effect of JC were quercetin, licochalcone B, (+)-catechin, kaempferol, and emodin. Conclusions : This study provides the molecular targets and potential pathways of JC on inflammation. It can be used as a basic data for using JC for various inflammatory disease in traditional korean medicine clinic.

Objectives : Forsythiae Fructus has been reported to have anti-inflammatory effects in many diseases, and Corydalis Tuber has been used as a pain suppressor in Eastern Asia. However, the protective effects of individual water extract of Forsythiae Fructus (FF) and Corydalis Tuber (CT) and the mixture of FF and CT (FC) on chronic pancreatitis (CP) were not well-investigated. Therefore, we investigated the protective effects of FF, CT, and FC on CP in mice. Methods : To induce CP, cerulein was injected 6 times a day, 4 times a week for 3 weeks. 1 h before the every cerulein injection, 200 mg/kg of FF, CT, or FC was intraperitoneally injected to mice. Histological analysis of pancreas was examined by hematoxylin and eosin stain and collagen deposition was examined by Masson's trichrome stain. Fibrogenic parameters such as α-smooth muscle actin (α-SMA), extracellular matrix (ECM) deposition, and fibrotic cytokines such as transforming growth factor (TGF)-β1 and platelet-derived growth factor (PDGF) were also analyzed by immunofluorescence stain and real-time PCR. Results : Histological damages in pancreas were inhibited by pre-treatment of FF or FC but not CT. α-SMA and ECM in pancreas were inhibited by pre-treatment of CT or FC but not FF. Moreover, the expression of TGF-β1 and PDGF in pancreas were inhibited by FF, CT or FC. Conclusions : Our results suggest that FC have protective effect on CP in mice through inhibition of α-SMA, ECM, TGF-β1 and PDGF in pancreas, and these findings could suggest new clinical strategy for CP.
