  • The nucleotide sequences of nuclear ribosomal ITS regions and chloroplast rbcL, matK and psbA-trnH regions of 30 individuals of Dendrobium moniliforme from several localities in four countries and 28 related species of Dendrobium were compared to investigate the genetic differences among Korean, Japanese, Taiwanese and Chinese D. moniliforme, and to verify the homogeneity of D. moniliforme, which is used as a traditional medicine in East Asia. A phylogenetic analysis showed that Korean D. moniliforme and Japanese D. moniliforme form a monophyletic group, with no significant differences between their nucleotide sequences. This confirms that they are the same species. However, the Chinese and Taiwanese D. moniliforme were polyphyletic. Various species related to D. moniliforme were located between the Korean-Japanese D. moniliforme and the Chinese-Taiwanese D. moniliforme, and other related species were found between individuals of Chinese-Taiwanese D. moniliforme. D. moniliforme is described in Japan, providing evidence that the Korean-Japanese D. moniliforme is the original species. In addition, our data suggest that the Chinese-Taiwanese D. moniliforme complex is a mixture of a range of other species. Further studies are required to understand the taxonomic identity of this species. In the Korean-Japanese D. moniliforme, there were almost no genetic differences among the localities, whereas the genetic heterogeneity was high among individuals of the Chinese-Taiwanese D. moniliforme.

  • 석곡은 난초과의 여러해살이풀 Dendrobium moniliforme의 지상부를 건조한 것으로 예로부터 양위생진(養胃生津), 자음제열(滋陰除熱) 등의 효능이 있어 해열, 진통의 작용과 위액분비 촉진, 혈압강하의 작용이 있는 것으로 알려져 있다. 본 연구에서는 석곡의 항염증 작용 기전을 알아보기 위하여 석곡 열수추출물을 대식세포주에 처리하여 NO 및 IL-$1{\beta}$의 생성에 미치는 영향을 조사하였다. LPS로 자극된 대식세포주 RAW264.7 세포에서 석곡은 NO 및 IL-$1{\beta}$ 생성과 iNOS 단백질 발현을 저해하였으며, LPS에 의해서 활성화되는 ERK, p38, JNK 효소의 활성을 현저히 억제하였다. 이 결과들로 보아 석곡의 항염증 작용이 MAPK 활성 저해로 인한 NO 및 IL-$1{\beta}$ 생성의 억제 때문인 것으로 사료된다.

  • To evaluate the antioxidative activity of the ethanol extracts from 116 domestic medicinal plants, each extract was added to palm oil and lard in 1,000 ppm level, and the induction time was measured by Rancimat method. Almost all plant extracts tested showed more or less antioxidative activity. The extracts which had strong antioxidative activity to palm oil and lard were Caesalpinia sappan L., Paeonia japonica Miyabe et Takeda, Dendrobium moniliforme (L.) Sw and Crcumae longa L. These extracts were fractionated with chloroform, ethyl acetate, butanol and water. Ethyl acetate layer of Caesalpinia sappan L. and Paeonia japonica Miyabe et Takeda showed marked antioxidative activity, and chloroform layer of Dendrobium moniliforme (L.) Sw and Crcumae longa L. ethanol extract had stronger antioxidative activity than all the other layers.

  • Antidolary active and anti-sugar mechanisms of the ova family (石斛; Dendrobii herba) ethanol extract (EED) were investigated. The EED was administered orally four times a day in a diabetic mouse induced by strepto Joe Toshin to reveal and reveal its pharmacological miracle through experimental studies that reduce the liver function of empty blood sugar, glythamic oxal acetate levels, insulin levels and glutamic acid trans aminaase and glutamic acid pyruvic acid trans amine. EED increased insulin secretion by glucose in RINm5F beta cells as well as intraperitoneal glucose intakes in L6 muscle cells. Thus, EED has shown great promise in displaying anti-diabetes activity not only by increasing insulin secretion but also by increasing intakes per cell, and hopes that future research on pharmacological mechanisms for quartz (Dendrobii herba) ethanol extract will be more active and contribute greatly to the treatment of diabetes.

  • Atopic dermatitis is a chronic, relapsing inflammatory skin disease associated with dysfunction of skin barrier and cutaneous hyper-reactivity to environmental triggers. In the previous study, cytotoxicity, antioxidant, anti-inflammatory and anti-allergic activities were investigated for various herbal extracts such as Aloe vera L. (AV), Viola mandshurica W. Becker (VM), Punica granatum L. (PG), and Dendrobium nobile L. (DN) in order to develop effective therapeutic herbal extracts for atopic dermatitis, In this study, anti-inflammatory activities of these herb extracts in lipopolysaccharide (LPS)-induced macrophage RAW264.7 cells were further examined to find the underlying molecular mechanisms. The RT-PCR (reverse transcription polymerase chain reaction) analysis showed that PG, DN and AV inhibited effectively the gene expression of pro-inflammatory cytokines IL-6 and IL-$1{\beta}$ in LPS-stimulated macrophages, while VM did not. The transfection and luciferase analysis exhibited that all herbal extracts hindered the activation of transcription nuclear factor kappa B (NF-${\kappa}B$). The western blot analysis indicated that AV blocked the activation of only JNK MAP (c-Jun N-terminal kinase mitogen-activated protein) kinase not p38 MAP kinase, while VM, PG and DN did not show the activation of both JNK and p38 MAP kinases. These results suggest that AV, VM, PG, and DN have anti-inflammatory activities and thus have the potential to reduce and alleviate the symptoms of atopic dermatitis.

  • The neuroprotective effect of methanolic extracts from Dendrobium nobile Lindl. (DME) against $H_{2}O_{2}$-induced neurotoxicity in PC12 cells was investigated. The treatment of PC12 cells with various DME concentrations under $H_{2}O_{2}$ resulted in the induction of protective effect in a dose-dependent manner, as determined by the results of an MTT reduction assay, an LDH release assays, and a morphological assay. Interestingly, we also detected reduction of apoptotic bodies and inhibition of caspase-3 activity by DME in $H_{2}O_{2}$-indeced PC12 cells. These data show that the neuroprotective effect of DME against PC12 cells might be related to the suppression of caspase-3 activation. Therefore, these results suggest that DME could be a new potential candidate as chemotherapeutic agents against neuronal diseases.
