Objectives : Dioscorea batas Decaisne (DB) has been known to be good for the digestive system on Eastern Asia. However, the protective effect of DB on acute pancreatitis (AP) has not been studied. In this study, we tried to investigate the protective effect of DB water extract on caerulein-induced AP.
Methods : To measure the protective effect of DB on AP, Mice were injected with cholecystokinin analogue caerulein (50 μg/kg) hourly for 6 times. DB water extract (200 or 400 mg/kg) or saline (control group) was administered orally 1 h before the first injection of caerulein. The mice were sacrificed at 6 h after the last injection of caerulein. The pancreas tissues and serum samples were immediately taken for further analysis.
Results : Administration of DB water extract showed the inhibitory effect on the increase of pancreas weight/body weight ratio, pancreatic histological damage. And the rise of serum lipase level was significantly reduced in DB water extract treatment group during AP in mice. However administration of DB water extract did not show significant reduction in serum amylase level. Also, mRNA levels of pro-inflammatory cytokines Interleukin (IL)-6 and Tumor necrosis factor (TNF)-α but not IL-1β were inhibited by administration of DB water extract.
Conclusions : Taken together, we found that administration of DB water extract ameliorates the severity of caeruleininduced AP, which suggests the potential to be an effective treatment on AP.

Objectives : In the Korean Pharmacopoeia 12th edition (KP 12) and the Korean Herbal Pharmacopoeia (KHP), two authentic herbal medicines are described, namely Bang-gi (Cheong-pung-deung) and Mok-bang-gi , respectively. In China, Bun-bang-gi is also used as herbal medicine. This study was conducted to develop a molecular authentication tool for distinguishing the three herbal medicine used as Bang-gi , which are Sinomeni Caulis et Rhizoma (Rhizome of Sinomenium acutum), Stephaniae Tetrandrae Radix (Root of Stephania terandra ), and Cocculi Radix (Root of Cocculus trilobus ).
Methods : Twelve samples of three species (four samples of S. acutum, five samples of S. tetrandra, and three samples of C. trilobus) were collected from different habitats. The sequences of internal transcribed spacer (ITS) regions were obtained and comparatively analyzed to design the species-specific sequence characterized amplified region (SCAR) primers. The specificity of each pair of SCAR primers that amplified species-specific amplicon was evaluated for establishing the singleplex and multiplex PCR assay tools.
Results : The singleplex SCAR markers show discriminability in C. acutum, S. tetrandra, and C. trilobus. These SCAR markers were also efficiently authenticated three species in the multiplex SCAR amplification using single PCR reaction. Furthermore, these PCR assay methods were applicable to authenticate dried herbal medicines distributed in the markets.
Conclusions : The SCAR markers and PCR assay tools help discriminate the three herbal medicines used as Bang-gi at the species levels and provide a reliable genetic method to prevent the inauthentic distribution of these herbal medicines.

Objective : The present study comparatively analyzed the anti-obesity effect of Arctium lappa L. roots with and without microwave processing.
Methods : Four HFD groups except for the Normal group (n=8) were allocated: Control, microwave-processed dried Arctium lappa L. roots (MAL) extract 400 mg/kg/d (MAL400), MAL extract 800 mg/kg/d (MAL800), and the dried Arctium lappa L. roots (DAL) extract 800 mg/kg/d (DAL800). The efficacy of MAL and DAL was confirmed in terms of the serum biochemical index, protein expressions related to the synthesis of triglyceride (TG) and total cholesterol (TC) and β-oxidation, and histopathological staining.
Results : Both MAL and DAL treatments significantly reduced final body weight and body weight gain. MAL800 treatment significantly reduced serum TG, TC, low-density lipoprotein cholesterol, and leptin levels, but the serum high-density lipoprotein cholesterol and adiponectin concentrations were dramatically increased. In particular, leptin in the MAL800 group was reduced by 14.1% compared with the DAL800 group. Moreover, the MAL800 treatment showed an effect superior to the DAL800 treatment in the reduction of serum TC, the sirtuin 1 (Sirt1) activation, and the inhibition of 3-hydroxy-3-methyl glutaryl coenzyme A reductase (HMGCR) gene expression. In particular, unlike the DAL800 treatment, MAL treatment significantly led to the activation of peroxisome proliferator-activated receptor alpha (PPARα). Subsequently, PPARα meaningfully regulated downstream proteins associated with β-oxidation.
Conclusion : These findings suggest that Arctium lappa L. roots with microwave processing effectively ameliorate obesity through the regulation of leptin and TC and the promotion of β-oxidation compared with Arctium lappa L. roots without microwave processing.

Objectives : In this study, we investigated the synergistic protective effects of medicinal herbal mixture (HME) including Mori Ramulus (MR), Acanthopanacis Cortex (AC), Eucommiae Cortex (EC), and Black soybean (BS) in C2C12 cells, mouse myoblasts.
Methods : Effects of HME on cell viability of C2C12 myoblasts were monitored by MTT assay. Anti-atrophic activity of HME was determined in myoblasts and myotubes under oxidative stress by H2O2. C2C12 myoblasts were differentiated into myotubes in a medium containing 2% horse serum for 6 days. After that, we measured that expression of MyoD and myogenine, the myogenic regulatory factors, to identify the mechanism of inhibiting muscle atophy after HME treatment. In addition, suppression of phosphorylation of Akt, FoxO3a and MARF-1, transcription factors of degradation proteins were analyzed via western blotting.
Results : As a result of MTT, HME there was no show cytotoxicity up to a concentration of 1 mg/ml. The cytoprotective effects on oxidative stressed myoblast and myotube was better in HME extract than those of MR, AC, EU, and BS, respectively. HME treatment in Myotube induced by oxidative stress after H2O2 treatment increased Myo D, Myogenine activation, and Akt, FoxO3a phosphorylation and decreased expression of MuRF-1. As the results, HME has synergistic effects on protection against proteolysis of C2C12 myotubes through activation of the Akt signaling pathway under oxidative stress.
Conclusions : These results suggest that HME may also be useful as a preventing and treating material for skeletal muscle atrophy caused by age-related diseases.

Objectives : In the present study, we assessed the effects of water extract of Ulmus davidiana (UED) on the learning and memory impairments induced by scopolamine in mice through its favorable acetylcholinesterase (AChE) activity and antioxidant effect.
Methods : The memory and cognitive enhancing effect of the UDE was investigated using a passive avoidance test, the Morris water maze test and Y-maze test in mice. In addition, to examine the mechanism of UDE using acetylcholinesterase (AChE) and antioxidant activity.
Results : The water extract of UDE (100, and 200 mg/kg) significantly reversed the scopolamine-induced cognitive impairments in the passive avoidance test (P < 0.05). Moreover, UDE (100, and 200 mg/kg) also improved escape latencies in training trials and increased swimming times and distances within the target zone of the Morris water maze (P < 0.05). On the Y-maze test, UDE (100, and 200 mg/kg) also significantly reversed scopolamine-induced cognitive impairments in mice (P < 0.05). In an in vitro study, UDE was found to inhibit acetylcholinesterase, changes in neurotrophic factor (CREB), and antioxidant activity in a dose-dependent manner.
Conclusions : The water extract of UDE dramatically possesses the anti-amnestic and cognitive-enhancing activities related to the memory processes, and these activities were parallel to treatment duration and dependent on the learning models. These results suggest that the administration of UDE enhances learning and memory, and that this effect is partially mediated by ERK-CREB-BDNF signaling and the survival of immature neurons.

Objective : This study was conducted to investigate antidiabetic effects of chunggugjang with medicinal herbal complex (CJ) in streptozotocin (STZ)-induced animal models.
Method : STZ (65 mg/kg) was injected intraperitoneally to induce diabetes. Then rats were divided into 5 groups ; NG (normal diet + 0.9% saline), COS (STZ +saline 5 mL/kg), COB (STZ + fermented soybean(100 mg/kg), CJ 100/200 (STZ+CJ(100 and 200 mg/kg), CJ 300/600 (STZ+CJ(300 and 600 mg/kg). 4 weeks later, oral glucose tolerance test (OGTT) was performed. After sacrificing rats, serum levels of blood urea nitrogen (BUN), creatinine, aspartate amino transferase (AST), alanine amino transferase (ALT), total cholesterol (TC), and triglyceride (TG) were measured and histological changes were observed.
Result : Body weight change and food efficiency ratio (FER) were decreased in the CJ 300/600 group than in the COS group. But, there was no change in water intake. Serum levels of glucose, AST, ALT and BUN were lower in the CJ 300/600 group than in the COS group. Also, TG, TC, and creatinine were decreased in the CJ 300/600 group than in the COS group. According to OGTT, 120 minutes postprandial glucose levels were lower in the CJ 300/600 group than in the COS group. In addition, administration of CJ extracts restored histopathological damage.
Conclusion : The results suggest that CJ can be used as a functional material for diabetes treatment as it has the effect to improve pathological symptoms in STZ-induced diabetic rats.
