In "Sanghanlon(傷寒論)", there are several articles to explain about Oryeongsan's syndrome. Most important articles of them are No. 72 and No. 75. Oryeongsan is explained by many doctors as a prescription to control exterior and interior, because they considered that symptoms of 72 and 75 articles were caused by exterior and interior's syndrome. Accordingly, they explained that RAMULUS CINNAMOMI(桂枝) and warm water remove exterior pathogens, and PORIA(茯笭) and others remove interior fluid retention. But considering the origin of a fluid retention, RAMULUS CINNAMOMI's effects are rather activating Yang(通陽) and warming Yang(溫陽) than removing exterior pathogens. The fluid retention is cauesd by insufficiency of Yang energy, because body fluid's spreading depends on Ynag energy. RAMULUS CINNAMOMI's effects of activating Yang and warming Yang improve the fluid retention and spread body fluid to the whole body. Some doctors use CORTEX CINNAMOMI(肉桂) instead of RAMULUS CINNAMOMI, because CORTEX CINNAMOMI's effects of activating Yang and warming Yang are better than RAMULUS CINNAMOMI's. There are many opinions about what is the main symptom of Oryeongsan's syndrome, but the difficulty in urination is understood by most doctors as the main symptom of Oryeongsan's syndrome. From the viewpoint of that, they understand that Oryeongsan's main effect is the induce diuresis. But the induce diuresis does not only mean a urination. The induce diuresis must be understood as the removing fluid retention by sweat and urine through the spreading body fluid.

Cinnamomi Ramulus is one of the medicinal plants that have been used to improve various diseases caused by insufficient blood circulation. This study was performed for the investigation of vasodilation efficacy ethanol extract of Cinnamomi Ramulus (CR). CR exhibited vascular relaxation against phenylephrine (PE, $10^{-6}M$)-, KCl- and NaF-induced contraction in rat thoracic aorta. In addition, its relaxation was endothelium-independent. Treatment of potassium channel blockers such as gilbenclamide (Gli, $10^{-5}M$), tetraethylammonium (TEA, 1 mM) and 4-aminopyridine (4-AP, 0.2 mM) did not effect on the relaxation of CR. The relaxant effects were also not inhibited by pre-treatment of rat aorta with L-NAME ($10^{-4}M$), methylene blue ($10^{-5}M$), indomethacin ($10^{-5}M$), and atropine ($10^{-6}M$). However, nifedipine ($10^{-5}M$), L-type $Ca^{2+}$ channel blocker, in part attenuated the relaxation of CR ($0.2\;mg/m{\ell}$), but SK&F96365 ($3{\times}10^{-5}M$), receptor activated $Ca^{2+}$ channel blocker and 2-APB ($10^{-4}M$), store operated $Ca^{2+}$ channel blocker did not affact dilation of CR. These findings suggest that the endothelium-independent relaxation effect of CR is partly related with inhibition of $Ca^{2+}$ influx via voltage dependent $Ca^{2+}$ channel.

Objectives : We studied anti-allergic effects of Cinnamomi Ramulus(CR) herbal acupuncture and Cinnamomi Ramulus extract. Methods : In vivo, animals were herbal-acupunctured with CR at both ST36s three times for 5 days. Then, we induced active systemic anaphylatic shock using compound 48/80 in ICR mice, and passive cutaneous anaphylaxis using anti-DNP IgE in Sprague Dawley rat. In vitro, we measured cell viability, ${\beta}$ -hexosaminidase release and the expressions of IL-4, TNF-${\alpha}$ and COX-2 mRNA in RBL-2H3 cells after treatment of various concentrations of CR extract. Results : In vivo, CR herbal acupuncture pretreatments at both ST36s inhibited compound 48/80-induced active systemic anaphylatic shock. Passive cutaneous anaphylaxis was inhibited by CR herbal acupuncture pretreatments at both ST36s and optional points. In vitro, CR extract treatments did not affect on cell viability and inhibited ${\beta}$-hexosaminidase release. CR extract treatments also decreased the expressions of IL-4, TNF-${\alpha}$ and COX-2 mRNA in RBL-2H3 cells. Conclusions : These results suggest that CR herbal acupuncture and CR extract should be beneficial in the inhibition of allergic inflammatory response.

Proliferation of vascular smooth muscle cell(VSMC) is one of the key features in onset of atherosclerosis and restenosis after vascular surgery such as stent implant. Atherosclerotic plaques are usually composed of collagen, elatsin and smooth muscle cells. Release of matrix metalloproteinases(MMPs) is considered to have correlation with development of atherosclerotic plaques. Based on the hypothesis that MMP inhibition would be helpful in the treatment of atherosclerosis, we investigated inhibition of MMP activity and migration of TNF-$\alpha$-induced human aortic smooth muscle cell(HASMC) by Cinnamomi Ramulus(CC). The result from gelatin zymography showed that CC inhibited MMP-9 activity in a dose-dependent manner. In addition, CC considerably inhibited the migration of HASMC induced by TNF-$\alpha$, while it showed little cytotoxic effect on HASMC. These results suggest that CC can be a potential anti-atherosclerotic agent through inhibition of MMP-9 activity and SMC migration.

In order to examine anti-inflammatory effect of Cinnamomi Ramulus (CR) alcohol extract on rheumatoid arthritis, the present study investigated the viability and TNF-${\alpha}$ production in Raw264.7 cells treated with CR and collagen induced arthritis in DBA/1J mice which were orally administered with CR prior to immunization. The results are as follows: CR extract at $20{\mu}g/ml$ inhibited the viability of Raw264.7 by 50%. CR at 15 and $20{\mu}g/ml$ showed a significant decrease in TNF-${\alpha}$ levels from Raw264.7 cells treated with LPS. CR administration decreased arthritic index in DBA/1J mice immunized with bovine collagen type II but it did not reach statistical significance. CR administration significantly decreased spleen weights obtained from mice in 6 weeks after immunization. CR administration significantly decreased serum anti-type II collagen antibody levels compared with control group. CR administration decreased serum IL-6 levels compared with control group but it did not reach statistical significance.

Objectives: Cinnamomi Ramulus (CR), the young twig of Cinnamomum loureirri nees, has been used for treating symptoms related to pain, rheumatic arthritis and inflammation in Korean herb medicine. This study was carried out to investigate the anti-inflammatory effect of CR in vivo and in vitro. Methods: Extracts of CR were prepared and the chemical components of the extracts were examined by gas chromatography-mass spectrometry (GC-MS). The extracts were administrated to the rat paw edema model induced by carrageenan to evaluate the anti-inflammatory effect of CR. The expressions of nitric oxide (NO), prostaglandin E2 (PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 were also quantified in lipopolysaccharide(LPS)­induced RAW 264.7 macrophages to survey the effect of CR in vitro. The main components were cinnamaldehyde and coumarin. Results: We examined the anti-inflammatory activity of the $80\%$ ethanol extract of Cinnamomi Ramulus in vivo by using carrageenan-induced rat paw edema model. Maximum inhibition of $54.91\%$ was noted at the dose of l1000mg/kg after 2 hours of drug administration in carrageenan-induced rat paw edema and this showed a potent anti-inflammatory effect. Conclusions: The results showed that Cinnamomi Ramulus suppressed dose-dependently LPS-induced NO production in RAW 264.7 macrophages and also decreased iNOS protein expression. Cinnamomi Ramulus also showed a significant inhibitory effect in LPS-induced PGE2 production and COX-2 expression.

For the quality control of traditional herbal medicine, Cinnamomi Ramulus, simultaneous determination of cinnamic acid, cinnamaldehyde, and 2-methoxycinnamaldehyde was established by using a high performance liquid chromatographic (HPLC) method with diode array detector. To separate three constituents, Eclipse XDB C18 ($5{\mu}m$, $4.6{\times}250mm$) was used with 0.1% acetic acid and acetonitrile. Validation of the chromatography method was evaluated by linearity, recovery, and precision test. Calibration curve of standard components showed excellent linearity ($R^2$ >0.9999). A simple and efficient method by HPLC was developed to evaluate the quality of traditional herbal medicines made from Cinnami Ramulus. Three major bioactive ingredients in 30 samples that are from China(8) and Vietnam(22) were separated and quantified.

Objectives : For evaluation of preventive and anti-diabetic activities of Cinnamomi ramulus(CR) herbal acupuncture on pancreatic islet damage in streptozotocin(STZ)-induced diabetic rat. Methods : CR herbal acupuncture was performed at Bisu($BL_{20}$) for 3 weeks subcutaneously starting1 week before STZ i.p. injection. SD rats were divided into four groups(n=10 for each group); 1) NC group, non-treated normal control group, 2) STZ group, STZ administered control group, 3) CR125 group, CR(125mg/kg) + STZ administered group, and 4) CR250 group, CR(250mg/kg) + STZ administered group. Results : Both of CR250 and CR125 groups showed increase in insulin secretion and decrease in the level of serum triglyceride and non-esterified fatty acid in a dose-dependent manner compared to the STZ group. Only CR250 group showed decrease in the levels of glucose and total cholesterol compared to the STZ group. CR herbal acupuncture prevents $\beta$-cell damage of pancreatic islet, showing round figure on the sections of the pancreas. In the pancreatic cells, expressions of iNOS, JNK-2, P-JNK-1/2 and ERK-1/2 were decreased compared to the STZ group. CR herbal acupuncture solution did not show any cytotoxicity by MTS assay and inhibited expressions of iNOS and COX-2 in the STZ-induced diabetic rats. Conclusions : Therefore, we suggest that CR herbal acupuncture may act as a prophylactic as well as a therapeutic modality for diabetes mellitus.

Objectives : In the present study, the contents of cinnamic acid and cinnamaldehyde in three different parts of Cinnamomi Ramulus (CR) (the whole body, the bark part, and the wood part) was evaluated using UPLC (ultra performance liquid chromatography) in order to investigate a suitable cutting method. Methods : Analysis was performed on SMART LC with UV detector. Reference compounds were separated on Inertsil ODS-4 column ($2.1mm{\times}50mm$, $3{\mu}m$, GL Science, Japan) using isolation elution with water and acetonitrile each containing acetic acid at a flow rate of $500{\mu}L/min$. Additionally, samples of CR were purchased from pharmacy of medicinal herb. Results : The correlation coefficients of the cinnamic acid and cinnamaldehyde levels showed good linearity ($r^2{\geq}0.9999$) over the linear ranges. Furthermore, the bark part exhibited higher concentration levels of reference compounds than the wood part in all samples. In addition the bark exfoliation rates in oblique and perpendicular-long cut samples of CR were lower than the perpendicular-short cut samples. Conclusions : These results suggested that the optimal cutting method would be able to reduce the bark exfoliation. Therefore, the oblique or perpendicular-long cutting method is considered to be a better cutting type than the perpendicular-short cutting method.

Objectives : A persistent inflammatory response can cause diseases such as fibrosis, cancer, and allergies. This study aimed to investigate the anti-inflammatory activity of Curcumae longae Rhizoma and Cinnamomi Ramulus Mixture (CCM) in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Methods : The total polyphenol and flavonoid contents of CCM were confirmed through an in vitro experiment. Also, radical scavenging activities of 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and Hydroxyl were confirmed. Moreover, ferric reducing antioxidant power (FRAP) activity were confirmed. After, CCM (50, 100, and 200 ㎍/mL) were applied to 0.1 ㎍/mL LPS-stimulated RAW264.7 cells. The levels of nitric oxide (NO) and pro-inflammatory cytokines in the supernatant fraction were determined. Also, the expressions of mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) pathways were detected using Western blot. Results : As a result of in vitro experiments, there was an excellent antioxidant activity in CCM-treated cells. In addition, in RAW264.7 cells stimulated with LPS, the increased NO level was inhibited in a concentration-dependent manner by the treatment of CCM. In addition, inflammatory cytokines production were significantly inhibited in a concentration-dependent manner in CCM-treated group. CCM treatment significantly decreased the protein expressions of MAPKs. Moreover, the expressions of NF-κBp65 and cyclooxygenase-2 (COX-2) were significantly decreased when 200 mg/kg of CCM was applied, and phospho-inhibitor of nuclear factor kappa B-α (p-IκBα) and inducible nitric oxide synthase (iNOS) were significantly decreased at all concentrations treated with CCM. Conclusion : Our findings show that CCM exhibited excellent antioxidant activity and exhibited superior anti-inflammatory effect through the MAPKs and NF-κB pathways in LPS-stimulated RAW 264.7 macrophages.
