Nanoparticles have wide-scale applications in various areas, including medicine, chemistry, electronics, and energy generation. Several physical, biological, and chemical methods have been used for synthesis of silver nanoparticles. Green synthesis of silver nanoparticles using plants provide advantages over other methods as it is easy, efficient, and eco-friendly. Nanoparticles have been extensively studied as potential antimicrobials to target pathogenic and multidrug-resistant microorganisms. Their applications recently extended to development of antivirals to inhibit viral infections. In this study, we synthesized silver nanoparticles using Cinnamomum cassia (Cinnamon) and evaluated their activity against highly pathogenic avian influenza virus subtype H7N3. The synthesized nanoparticles were characterized using UVVis absorption spectroscopy, scanning electron microscopy, and Fourier transform infrared spectroscopy. Cinnamon bark extract and its nanoparticles were tested against H7N3 influenza A virus in Vero cells and the viability of cells was determined by tetrazolium dye (MTT) assay. The silver nanoparticles derived from Cinnamon extract enhanced the antiviral activity and were found to be effective in both treatments, when incubated with the virus prior to infection and introduced to cells after infection. In order to establish the safety profile, Cinnamon and its corresponding nanoparticles were tested for their cytotoxic effects in Vero cells. The tested concentrations of extract and nanoparticles (up to 500 μg/ml) were found non-toxic to Vero cells. The biosynthesized nanoparticles may, hence, be a promising approach to provide treatment against influenza virus infections.

To evaluate the quality of the crude drugs using three kinds of Cinnamomum Cortex (CC), Vietnamese CC (VCC, the stem bark of Cinnamomum obtusifolium), periderm-peeled Chinese CC (PPCC, periderm-peeled stem bark of C. cassia), Chinese CC (CCC, stem bark of C. cassia) and a Cinnamomi Ramulus (CR, the twig of C. cassia), the four essential oils were prepared by steam distillation method. Cinnamaldehdye (CAN) and an unknown substance tentatively named hydroxy-cinnamaldehdye(HCNA) were detected in the four essential oils by gas chromatography-mass spectrometry, the contents of which are significantly different one another. Vietnamese CC had the highest content of HCNA whereas CR had the highest CAN content and the lowest HCNA. Vietnamese CC exhibited the greatest cytotoxic activity against the cancer cell lines, A549, HepG-2, HL-60, P-388, U-937, and KB and CR the lowest cytotoxicity. Contents of CAN and HCNA in CCC and PPCC are positioned between VCC and CR. These results suggest that measurement of HCNA and cytotoxicity may determine the quality of CC and CR.

계지에서 분리한 보체계 활성화 다당의 보체 활성화양식과 다당의 당쇄결합에 관하여 검토하였다. 계지 보체계 활성화 다당획분들(CC-IIIa, CC-IIIb, CC-IIIc)들은 정상인의 혈청중에 존재하는 주요 보체성분인 C3를 활성화하여 C3a와 C3b 보체 산물을 생성 시켰는데 이 과정은 anti-human C3를 이용한 면역전기영동을 실시하여 확인하였다. $Ca^{++}$ 유무시의 보체계 활성을 측정한 결과 계지에서 분리된 CC-IIIa-3는 고전적 경로(classical pathway)와 부경로(alternative pathway)를 동시에 활성화시킴을 확인하였다. CC-IIIa-3을 메틸화하여 GC/MS로 분석한 결과 비환원 말단의 galactopyranose와 glucopyranose가 확인되었고 1,2-linked rhamnopyranose, 1,6-linked mannopyranose, 1,3-linked glucopyranose, 1,6-linked galactopyranose 등이 확인되었다.

The present study evaluated the effects of a mixture of Galla rhois and Cinnamomum cassia extracts (GCE) (1 : 1, w/w) on susceptibility to the colonization of Campylobacter (C.) jejuni in broilers. Eighty two-week-old broilers (n = 20 per group) were used to estimate the efficacy of GCE against C. jejuni infection via drinking water. Antibacterial activity testing revealed that the minimum bactericidal concentration of GCE against C. jejuni was 2.5 mg/mL. Broilers challenged with C. jejuni were administered 0.0 (Non-GCE), 2.5 (GCE-2.5), 5.0 (GCE-5.0) and 10.0 g/L (GCE-10) GCE for 7 days, and the cecal contents were collected from five broilers per group on the 1st, 3rd, 5th, and 7th day post-treatment. On day 3 post-administration, the number of C. jejuni in GCE-5.0 (p < 0.05) and GCE-10 (p < 0.01) was significantly decreased relative to Non-GCE, while on day 7 those in all GCE-treated groups were significantly decreased compared to the Non-GCE group (p < 0.001). Hematological and blood biochemical analysis revealed no significant differences in parameters between the Non-GCE and GCE-treated groups. Based on the results of the present study, GCE was identified as a safe and alternative candidate to suppress C. jejuni colonization in broilers.

본 연구는 내측반월판 절제와 전십자인대 단열로 유발된 랫드 골관절염 모델을 이용하여 계피 (Cinnamomum cassia Blume, 육계(肉桂)) 추출물의 연골손상 방지에 대한 효과를 평가하였다. 골관절염유발 랫드 48마리를 군당 8마리씩 6군으로 음성 대조군과 골관절염 대조군, 체중당 diclofenac 2 mg 투여군, 계피 추출물 25 mg과 50 mg, 100 mg 투여군으로 각각 분류하여 수술 1주 후부터 12주동안 투여하였다. 연골 소실과 관절의 불안정성은 계피 추출물과 diclofenac 투여군이 골관절염 대조군과 비교할 때 유의하게 감소하였다(p < 0.05). 병리조직학적 평가에서 연골의 퇴행은 계피 추출물 투여량에 따라 용량 의존적으로 개선됨이 확인되었다(p < 0.01). 계피 추출물 투여군에서 관절구조 퇴행성 변화의 감소와 Safranin-O 염색 정도의 용량 의존적인 증가를 보여 연골 퇴행이 억제됨을 확인하였다. Diclofenac이 골관절염 진행에 있어 활성화된 caspase-3와 절단된 poly(ADP-ribose) 중합효소에 유도된 세포자멸사 표지율 증가에 별 다른 영향을 주지 않았지만 계피 추출물 투여군에서는 이들 세포자멸 표지자에 대한 반응세포는 유의하게 감소되었다(p < 0.05). 그러나, diclofenac과 계피 추출물 투여군은 5-bromo-2-deoxyuridine의 섭취에는 영향을 주지 않았다. 이러한 결과에서 계피추출물이 항염활성과 항세포 자멸 활성을 통해 관절연골에 보호 효과가 있음을 보였다.

Objectives : The aim of this study was to investigate the immunopotentiating activity of combine extract that Silkworm and Cinnamomum cassia. Recently, acute epidemic diseases such as cold and viral respiratory diseases have been emerging. So, interested in immunity enhancement has been increasing, and research on natural products to promote immunity activity has been actively conducted. Methods : To confirm the immunopotentiating activity effect, Silkworm (SW), Cinnamomum cassia (CC), and SWCC combined extracts were treated 14 days at 300 mg/kg/day. The changes of glutamic oxalacetic transaminase (GOT), glutamic pyruvate transaminase (GPT) in serum were analyzed after experiment. The changes in the total spleen cell number were measured. Immune cells in spleen were analyzed using fluorescence activated cell sorter (FACS). also, analyzed the expression of cytokines in spleen. Results : Total number of cells in the spleen and FACS analysis of T lymphocytes activated in the spleen showed that the SWCC combined treated group had much higher frequency of active cells than both single groups. The ratio of CD4+CD8+, CD4+CD69+ and CD4+CD25+ T cells in spleen, SWCC is higher than other groups except Nor in CD4+, CD4+CD69+, CD4+CD25+ T cells. The results of this study suggest that SWCC can help immune function via IL-2, IL-10, IL-12, IFN-${\gamma}$ cytokine production, increased T lymphocytes and splenocyte proliferation. Conclusion : Therefore, these results suggested that the SWCC combined extracts administration increase stronger immunity enhancement than when SW and CC adminstration.

Objectives : Silkworm is known as immunomodulatory substances and contain various bioactive compounds such as serine, tyrosine and alanine. The aim of this study was to investigated the immunopotentiating activity of combine extract that silkworm and food materials (Eucommia ulmoides, Angelica gigas, Acanthopanax, Allium hookeri, Cinnamomum cassia, Liriope platyphylla, Curcuma longa, Achyranthes japonica, Alpinia oxyphylla, Adenophora triphylla). Methods : Among 10 kinds of food materials, to select food materials with the effect of enhancing the immune function mouse splenocyte proliferation ability was measured by 3-[4,5-dimethylthiazol-2-y]-2,5-diphenyl terazolium bromide (MTT) assay. Then, combine extract of silkworm and food materials were evaluated that mouse splenocyte proliferation ability by EZ-cytox cell viability assay. Morever, cytokines production such as IL-2, IL-4, IL10, IL12, $IFN-{\gamma}$ on mouse T lymphocyte stimulated with concanavalin A (ConA) was measured. Results : Eucommia ulmoides, Acanthopanax, Allium hookeri, Cinnamomum cassia, Liriope platyphylla has high proliferation ability of mouse splenocyte compared with Curcuma longa, Achyranthes japonica, Alpinia oxyphylla, Adenophora triphylla. The silkworm and food material combined extract has a relatively high proliferation ability of mouse splenocyte proliferation when the silkworm and food materials are used as a single material. In particularly, combined extract of silkworm and Cinnamomum cassia was stimulate cytokine production on T lymphocyte such as IL12, $IFN-{\gamma}$. Combined extract of silkworm and Liriope platyphylla was stimulate cytokine production on T lymphocyte such as IL2, IL4, IL10. Conclusion : In conclusion, the combined extract of the silkworm and Cinnamomum cassia or Liriope platyphylla may enhance immune function by regulating mouse splenocyte proliferation and stimulating cytokine production.
