  • Objectives : External form and internal intersection of Phragmites communis were observed by the parts of usage (leaves, stems, and roots). Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Results : 1. The intersection of Phragmitis Folium was typically characterized as Gramineae plants, which was perfectly distinguished with Phragmitis Rhizoma and Phragmitis Caulis. 2. The cortex of Phragmitis Rhizoma has a large rectangular pore space, but Phragmitis Caulis does not. Conclusion : Phragmitis Folium, Phragmitis Caulis, and Phragmitis Rhizoma can be distinguished by microscope.

  • Objectives: This study was designed to find the effect of Phragmitis Rhizoma (PR) herbal-acupuncture solution on the inflammatory cytokine and chemokine secretion in human mast cell (HMC) and human alveolar epithelial cell 549 (A549) lines. Methods: Histamine levels in HMC after PR herbal-acupuncture solution treatment were measured with ELISA. Other cytokines and chemokines levels such as interleukin 8 (IL-8), monocyte chemoattractant protein-1 (MCP-1), and chemokine (C-C motif) ligand 5 (Ccl5, RANTES) in A549 were measured with flow cytometry CBA system. Results: In the PR herbal-acupuncture solution treatment group, the expression of histamine, IL-8, MPC-1, Ccl5, and RANTES decreased significantly. Conclusions: The results support that PR herbal-acupuncture solution had a suppressive effect on cytokine-induced inflammation.

  • Objectives: Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis Trin., which has been prescribed in traditional Korean medicine to relieve fever and vomiting and to nourish the body fluids. Recently, the protective effect of Phragmitis Rhizoma extract or its components on myelotoxicity and inflammatory responses have been reported, but no study has yet been conducted on oxidative stress. Methods: The present study investigated whether an ethanol extract of Phragmitis Rhizoma (PR) could protect against cellular damage induced by oxidative stress in Chang liver cells. Results: Pretreatment with PR significantly suppressed the hydrogen peroxide (H2O2)-induced reduction of Chang cell viability and generation of reactive oxygen species (ROS), thereby deferring apoptosis. PR also markedly inhibited H2O2-induced comet tail formation and phospho-γH2AX expression, suggesting that PR protected against oxidative stress-mediated DNA damage. PR also effectively prevented the inhibition of ATP synthesis in H2O2-treated Chang cells by inhibiting the loss of mitochondrial membrane potential, indicating that PR maintains energy metabolism through preservation of mitochondrial function while eliminating ROS generated by H2O2. Immunoblotting results indicated that PR attenuated the H2O2-induced downregulation of Bcl-2 and upregulation of Bax expression. Conclusions: PR protects against oxidative injury in Chang liver cells by regulating energy homeostasis via ROS generation blockade, which is at least partly mediated through inactivation of the mitochondria-mediated apoptosis pathway.

  • Phragmites communis rhizome (Phragmitis rhizoma) was extracted with 70% ethanol, and then the extract was fractionated sequentially using n-hexane, chloroform, and ethyl acetate as solvents. Among the solvent fractions of Phragmitis rhizoma extract, the polyphenol content in ethyl acetate fraction was the highest. The chloroform and ethyl acetate fractions possessed a good nitrite scavenging activity. In addition, each solvent fraction showed an effective lipid peroxidation inhibitory ability at a concentration of 10 mg/mL.

  • The H2O and 50% extracts of herbal medicines(HM) combinations which were consisted of Acanthopanacis Cortex. Phragmitis Rhizoma. Chaenomelis Fructus. Pruni pseudocerasi Semen and rice bran were prepared and administered orally before 40% ethanol administration in the males S.D rats. The 50% ethanol extract of HM (HM50E) showed blood alcohol decreasing activity and was fractionated again into HM50El and E2 by Sephadex LH-20 gel column chromatography. HM50E2 showed more effective blood ethanol decreasing activity than HM50El. (omitted)
