Type I interferons (IFNs) are critical mediators of the innate immune system to defend viral infection. Interferon regulatory factor (IRF) and signal transducer and activator of transcription (STAT) play critical roles in type I IFN production in response to viral infection. Luteolin is natural polyphenolic compounds that have anti-inflammatory, cytoprotective and anti-carcinogenic effects. However, the mechanism of action and impact of luteolin on innate immunity is still unknown. In this study, we examined the effects of luteolin on the lipopolysacchride (LPS)-induced inflammatory responses. Luteolin inhibited Type I IFNs expression of mRNA and increased interleukin(IL)-10 expression of mRNA. Next, we examined the protective effects of IL-10 using IL-10 neutralizing antibody (IL-10NA). Blockade of IL-10 action didn't cause a significant reduction of Type I IFNs than LPS-induced luteolin pretreatment. Pretreatment of luteolin inhibited the level of IRF-1, and IRF-7 mRNA and the nuclear translocation of IRF-3. Also, luteolin reduced the activation of STAT - 1, 3. Theses results suggest that luteolin inhibits LPS-induced the production of Type I IFNS by both IRFs and STATs not IL-10 and may be a beneficial drug for the treatment of inflammatory disease.

Objectives: This study aimed for establishing the discriminative criteria for Aucklandiae Radix, Inulae Radix, Vladimiriae Radix and Aristolochiae Radix, which can be confused as 'Mokhyang', because of similar appearances and synonyms. Methods: Morphological characteristics of dried herbal medicines were compared by macroscopic observation. To examine microscopic features of 'Mokhyang', paraffin embedding and the staining by using Ju's method were conducted. Physicochemical experiments were performed using HPLC analysis and antioxidant assay. Results: The types of stem, phyllotaxy and leaf shape were chosen as macroscopic criteria and the size, oil spots, color and root top as well as phloem and central cylinder were compared using microscopic features. The HPLC results showed different amounts of costunolide and dehydrocostuslactone among Aucklandiae Radix, Inulae Radix and Vladimiriae Radix. However, Aristolochiae Radix only contained aristolochic acid. The antioxidant assays also showed that Vladimiriae Radix exhibited strongest antioxidant activity followed by Aucklandiae Radix, Inulae Radix and Aristolochiae Radix. Conclusions: These results demonstrate that macroscopic, microscopic and physicochemical methods would be useful tools for the discrimination of 4 kinds of 'Mokhyang'.

Objective : This study aimed to compare the difference between $Angelica$ $decursiva$, Peucedanum $praeruptorum$ and $Anthriscus$ $sylvestris$ which have been used as herbal medicine, Jeonho (Angelicae Decursivae Radix) in Korea and provided the evidence to exclude $A.$ $sylvestris$ not to use as Joenho. Methods : The similarities of original medicinal herb with samples from local market were evaluated including morphological appearance and chromatographic fingerprint. In addition, relation between original medicinal herb and local samples were analyzed using statistical clustering methods. Results : $A.$ $decursiva$, $P.$ $praeruptorum$ and $A.$ $sylvestris$ represented different morphological appearances and chromatographic fingerprint. Several samples from China exhibited similar morphological and chromatographic appearance with $A.$ $decursiva$ or $P.$ $praeruptorum$. Eleven samples from Korea showed identical similarity to $A.$ $sylvestris$. Conclusions : Since $A.$ $sylvestris$ represented obvious differences compared to $A.$ $decursiva$ and $P.$ $praeruptorum$, it is required not to use $A.$ $sylvestris$ as medicinal herb, Jeonho. Additionally, exact identification and quality control must be applied to $A.$ $decursiva$ or $P.$ $praeruptorum$ from China in order to maintain therapeutical efficacy.

Objectives: The aim of this work is the making of morphological standard in platycodi radix. Methods: The external-internal morphological standards were determined by using stereoscope and butanol series. Conclusions: The external and internal characteristics according to the shape of original plant or herbal states. entirely correspond to all the literature on this subject. According to the place of production. the difference appears. (1) In the external shapes. as the Korean products. the distinction among the first. medium. poor class products was caused by the state of processing of desiccation. But as the foreign products, it was caused by the difference of size, color and especially color of circle. (2) In the internal shapes. the Mt. Baekdu region products is not skinned and has the deep state of suberization of cork phellogen. so it makes certain distinctional point. And the Korean products has the much latex tube group relatively and the bigger crevice than the foreign one.

Classified Emergency Materia Medica is a pharmacopoeia published by the government of the Song(宋) dynasty. After publishment, it had a decisive effect on East-Asian herbology of China, Korean & Japan. Sakae Miki(三木榮), Tameto Okanisi(岡西爲人) wrote papers on the subjects of type, publishing process, bibliographic terms of Classified Emergency Materia Medica published in the early and middle years of Joseon Dynasty. Moreover, Sakae Miki claimed that Classified Emergency Materia Medica from China had been a standard of herbology of Joseon Dynasty since its publishment, and herbology based on materia medica from countryside(鄕藥) also had occupied a part of herbology in Joseon Dynasty. Nevertheless the specific influences, from Classified Emergency Materia Medica to the medical books of Joseon Dynasty which established the herbology based on materia medica from countryside has never been handled so far. So I would like to investigate the influence of Classified Emergency Materia Medica to Joseon Dynasty, through a comparison with literature review. The main literatures for comparison are two representative medical books of Joseon Dynasty, Compendium of Prescriptions from the Countryside(1433) & Treasured Mirror of Eastern Medicine(1613), especially focusing on the pharmacognostic parts. The main comparing points on researching literatures will be the following: publication year of books; order of herbs; and quotations. This paper will show which edition of Classified Emergency Materia Medica was utilized to publish two medical books of Joseon Dynasty, and the process how Korean herbology based on materia medica from countryside was transformed after accepting Chinese herbology.

Objectives : Chrysanthemum boreale flower is widely distributed in Korea, Japan, China, and Eastern countries. C. boreale flower is also one of the herbs used for the treatment of various inflammatory disease in Korean Medicine. So, this research was designed to study anti-inflammatory effect of C. boreale flower and its mechanism. Methods : We investigated nitro oxide (NO) and prostaglandin $E_2$ ($PGE_2$) production by ELISA. And expressions of inducible nitric oxide synthase (iNOS), Cyclooxygenase-2 (COX-2) and nuclear factor-${\kappa}B$ P50/65 (NF-${\kappa}B$ P50, NF-${\kappa}B$ P65) were measured in RAW 264.7 murine macrophage cells induced by LPS. Results : MeOH ex., EtOAc fr., $CHCl_3$ fr. and Water fr. of C. boreale flower showed anti-inflammatory effect through inhibition of NO and PGE expression respectively. Among them, EtOAc fr. and $CHCl_3$ fr. inhibited production of NO and $PGE_2$ through inhibition of iNOS and COX-2 expression. And MeOH ex., EtOAc fr. and $CHCl_3$ fr. inhibited translocation of NF-${\kappa}B$ P65, NF-${\kappa}B$ P50 by inhibiting phosphrylation of $I{\kappa}B$. Conclusions : MeOH ex. EtOAc fr, $CHCl_3$ fr., and Water fr. of the C. boreale flower have anti-inflammatory activity.
