Objectives: The aim of the study was to evaluate the anti-asthmatic effect of alismatis rhizoma and alisol acetate B combination therapy in a murine asthma model. Methods: C57BL/6 mice were sensitized to and challenged with a mixture of ragweed, dust mite, and aspergillus to induce an asthma animal model. Alismatis rhizoma extract and alisol acetate B combination therapy was co-administered only in the experimental group. To evaluate the anti-asthmatic effect of the combination therapy, inflammatory cell counts in bronchoalveolar lavage (BAL) fluid were determined, and tissue was examined histologically with hematoxylin and eosin (H & E) and periodic acid-Schiff (PAS) stains, by enzyme-linked immunosorbent assay (ELISA) of IgE, IL-4, and IL-5, and with reverse transcription polymerase chain reaction (RT-PCR) of IL-5, IL-33, MUC5AC. Results: Alismatis rhizoma and alisol acetate B combination therapy reduced the number of inflammatory cells, alleviated histologic features, and down-regulated all the investigated asthma mediators, IgE, IL-4, IL-5, IL-33, and MUC5AC. Conclusions: According to the above results, alismatis rhizoma and alisol acetate B combination therapy may have therapeutic potential for asthma.

한방재료의 하나인 택사(Alismatis Rhizoma, AR)로부터 단백성 trypsin inhibitor(TI)를 분리, 정제하여 특성을 조사하였다. 정제과정은 0-80.% 포화 황산암모늄을 이용한 염석법, DEAE-cellulose ion exchange chromatography, Sep-hadex G-150 chromatography 등을 이용하였다. 정제된 ARTI의 분자량을 gel filtration과 SDS-PAGE 한 결과 모두 약 23,000 Da으로 나타나 monomer로 되어 있는 것으로 나타났다. 온도안정성에 있어 0-6$0^{\circ}C$에서는 안정하였으나 그 이상의 온도에서는 약 35%가지 안정성이 떨어졌다. ARTI와 상품화된 soybean kunitz inhibitor의 저해능을 비교해 본 결과 ARTI 및 soybean inhibitor 각각의 농도가 0.071 $\mu$M, 1.7 $\mu$M일 때 0.025 g/$m\ell$ trypsin활성을 50% 정도 저해하는 것으로 나타났다. ARTI의 trypsin의 가수분해반응에 대한 저해형태는 비경쟁적 저해형인 것으로 나타났으며 km값은 0.81 $\mu$M이었다.

Objectives Alismatis Rhizoma has been known to suppress inflammation and allergic reaction. However, the cellular target of Alismatis Rhizoma and its mechanism of action remain unclear. This study was designed to examine the effect of Alismatis Rhizoma extract (ALC) on the RBL-2H3 mast cells in vitro and on the OVA/alum sensitized mice ex vivo. Methods In the study, RBL-2H3 mast cells were cultured in minimal essential medium (MEM) for 24 hours, and treated separately with cyclosporin A and varying doses of ALC, and then stimulated with Phorbol 12-myristate 13-acetate (PMA) (50 ng/ml) and Ionomycin ($0.5{\mu}M$). The levels of IL-13, IL-4 were measured by ELISA analysis. The mRNA levels of IL-4, IL-5, IL-6, IL-13, GM-CSF, $TNF-{\alpha}$ were analyzed with Real-time PCR. Also, manifestations of MAPKs transcription factors and $NF-{\kappa}B$ p65 translocation were analyzed by western blotting in vitro. Subsequently, for ex vivo experiment, we induced allergic inflammation on Balb/c mice by OVA/alum and administered ALC orally. And we measured serum OVA-specific IgE level and IL-4, IL-13 in the splenocyte culture supernatant by ELISA analysis. Results ALC was shown to suppress mRNA expression of IL-4, IL-5, IL-6, IL-13, GM-CSF, $TNF-{\alpha}$, and to inhibit the IL-13, IL-4 production. Also ALC reduced an activation of mast cells specific signal MAPKs transcription factors and $NF-{\kappa}B$ p65 from the western blot analysis in in vitro experiment. In ex vivo, ALC oral adminstration decreased the level of OVA-specific IgE in serum, and IL-4, IL-13 in the splenocyte culture supernatant. Conclusions ALC is shown to reduce inflammation and allergic response by suppressing Th2 cytokines through the regulation of transcription factors MAPKs and $NF-{\kappa}B$ p65 in mast cells. Administration of ALC suppressed OVA-specific IgE in ovalbumin allergy model through the inhibition of Th2 cytokine. In conclusion, ALC can be considered as an effective treatment for allergic diseases such as atopic dermatitis.

Objectives : We try to compared the efficacy of six herbal medicines, Rhizoma Alismatis (RA), Fructus Crataegi (FC), Fructus Lycii (FL), Radix Curcumae (RC), Radix Salviae Miltiorrhizae (RSM), and Herba Artemisiae Scopariae (HAS), constituting KHchunggan-tang which was previously proven to be hepatoprotective on non-alcoholic fatty liver disease with combined properties of cellular steatosis, ROS production, and cytoprotection. Methods : HepG2 cells were pretreated with aqueous extracts of the six herb medicines at concentrations of 1, 10, 50 and 100 ${\mu}g/ml$ each, and treated with 0.5 mM palmitate consecutively. After 21 hrs, cell viability was assessed using MTT assay, and the percentage of cells with sub-G1 DNA content was measured using fluorescence-activated cell sorting after propidium iodide staining. Results : The first three extracts, RA, FC, and FL restored cell viability reduced by palmitate in MTT assay, and RA, FC, FL and RC inhibited palmitate-induced apoptosis in sub-G1 analysis. FL showed relatively weak potential only at tested maximal dose, and RA showed the greatest higher efficacy on this experimental cellular model of nonalcoholic fatty liver disease. Conclusions : According to this comparative experiment, Rhizoma Alismatis seems to have the most powerful potential among the six herbs constituting KHchunggan-tang, and consecutive further study seems to be required for more standardized and effective clinical application of KHchunggan-tang for treatment of non-alcoholic fatty liver disease.

Objective : The purpose of this study is to investigate the antioxidant activities of Alismatis Rhizoma herbal acupuncture by experimental methods. Methods : For this purpose, first, we put an emphasis in the control of enzymes of the antioxidant system in various changes inside the cell; these changes caused by the proliferation or the activation of the cell which were brought about by the handling of PMA and $TNF-{\alpha}$ into the THP-1 monocyte cell of the body each other. After that, we caused the acute oxidant symptom by the injection of AAPH into the mouse' abdominal cavity, and then applied the herbal acupuncture on S36 point(足三里), and finally, we measured the change of blood ingredient and the resistance against the activated oxygen of the red blood cell membrane, MDA, SOD, and catalase. Results : In vitro the revelation of $IL-1{\beta}$, IL-8, $TNF-{\alpha}$, NOS II and IL-6 were decreased and the revelation of IL-10, $TGF-{\beta}$, GM-CSFIL-12, GM-CSF and SOD were increased. The DNA-binding of $NF-{\kappa}B$ and AP-1 were activated and the formation of ROS in the THP-1 cell line was decreased. In vivo $IL-1{\beta}$ among producing the cytokine inside the plasma was meaningfully dwindled and the $INF-{\gamma}$ was meaningfully increased. The resistance of red blood cell membrane against the activated oxygen was meaningfully increased and the MDA formation was meaningfully dwindled, In the activation of hepatic antioxidase, the SOD was meaningfully increased. Conclusion : Alismatis Rhizoma herbal acupuncture by experimental methods has effected on the antioxidant activities.
