Lophatheri Herba of Lophatherum gracile Bronghiart(Gramineae) has long been used for treatment of inflammation, fever and edema in Korea. In order to investigate antibacterial activity of the Lophatheri Herba against Streptococcus mutans ATCC27351, paper disc test and pH check were carried out with 80% ethanol extract of Lophatheri Herba(LEX). The LEX showed significant antibacterial activity. And at the dose of 50 mg/kg, LEX showed signifiant inhibition on the paw edema, vascular permeability and myeloperoxidase activity in rat's paw tissue. These results indicate that LEX has antibacterial activity against the Streptococcus mutans and anti-inflammatory effect.

For distinguish between Lophatherum gracile and Phyllostachys nigra var. henonis based on natural shape and external-internal morphology of medicinal shape, general contents of oriental medicine were rearranged through bibliography. As a result, two medicinal stuffs indicated the difference in shape and structure(external-internal and powder)of origin plant bibiliographically. After this, this contents were utilized to give proof of many effective difference between two medicinal stuff.

Lophatheri Herba is the aerial part of Lophatherum gracile Bronghiart(淡竹葉, Gramineae). 25~75 cm in length. Stem: cylindrical with nodes, empty inside, externally pale yellowish green. Leaf: dehiscent of lanceolate lamina, shrunken and rolled, 5~20 cm long, 10~35 mm wide; surface: pale green ~ yellowish green, parallel-formed with veins of square reticulate, more distinct of appearance on the lower surface. Banbusae Caulis In Taeniam is the stringy strip derived from the stem with the peeled-off epidermis of Phllostachys nigra Munro var. henosis Stapf, and Phllostachys bambusoides Siebold et Zuccarini(竹葉, Gramineae). Irregular in size and shape, thin plane ~ strip-shaped, sometimes powdery, sometimes 1~3 mm thick. Outer surface: pale green ~ yellowish green, sometimes grayish white L. gracile and P. nigra have different origins although they show similar morphologic features. We were able to distinguish between L. gracile and P. nigra which are almost indistinguishable through this study. AFLP(Amplifide Fragment Length Polymorphism) was more suitable for identifying differences between L. gracile and P. nigra in comparison with other genetic analysis using chemical analysis. Therefore. molecular biological methods are believed to be useful for discovering origins of herbal medicines.

Lophatheri Herba, Patriniae Radix, Alli tuberosi Herba, and Menthae Herba have long been used externally for treatment of injuries or inflammations in Korea. This study was carried out to examine the anti-dandruff effect of the mixture made with equal parts of 70%-ethanol extracts of Lophatheri Herba, Patriniae Radix, Allii tuberosi Herba, and Menthae Herba (LPAM) and of each one above, compared with 1%-zinc pyrithione (Standard) used commercially as anti-dandruff. The results showed the mixture was more effective than each crude drug. The 10%-LPAM produced no toxicity in skin reaction test and eye irritation test, and showed significant antimicrobial activity against Pityrosporum ovale, the major cause of dandruff, and also showed significant anti-dandruff and itch-improvement effects on head skin.

The vasorelaxant effect of an extract of Lophatherum gracile Brongn (ELB) and its possible action mechanism were ascertained in aortic tissues isolated from rats. ELB relaxed endothelium-intact thoracic aorta in a dose-dependent manner. However, the induced vascular relaxation was abolished by removal in endothelium of the thoracic aorta. Pretreatment of endothelium-intact vascular tissues with $N^G$-nitro-L-arginine methyl ester (L-NAME) or 1H-[1,2,4]-oxadiazole-[4,3-$\alpha$]-quinoxalin-1-one (ODQ) significantly inhibited vascular relaxation induced by ELB. Moreover, ELB significantly increased cGMP production in aortic tissues, which was blocked by pretreatment with L-NAME or ODQ. The vasorelaxant effect of ELB was attenuated by tetraethylammonium (TEA), and glibenclamide. ELB-induced vasorelaxation was not blocked by atropine, propranolol, indomethacin, verapamil, and diltiazem. Taken together, the present study demonstrates that ELB dilates vascular smooth muscle via an endothelium-dependent NO-cGMP signaling pathway, which may be at least in part related with the function of $K^+$ channels.

We studied to know the anti-inflammation effect on water extracts of Lophatheri Herba which was growing in every places in our country. We objected free radical scanvenger effect and nitrite eliminate effect of the Lophatheri Herba water extracts, and the cell viabillity, the effects of Lophatheri Herba water extracts on NO production, iNOS synthesis induced by LPS. Free radical scavenger effects were $27.91{\pm}0.12%$, $38.96{\pm}0.10%$, $46.22{\pm}0.15%$ depend on 0.5, 1.0, 2.0 mg/ml each dose of Lophatheri Herba water extracts. Nitrite eliminate effects were $9.86{\pm}0.3%$, $80.61{\pm}0.23%$, $97.62{\pm}0.56%$ in 0.1, 1.0, 2.0 mg/ml Lophatheri Herba water extracts on pH 1.2. NO production and iNOS synthesis induced by LPS were reduced in RAW 264.7 cell by Lophatheri Herba water extracts. As the above results, Lophatheri Herba water extracts have anti-inflammation effects via NO production decrease, iNOS synthesis decrease mechanism. So Lophatheri Herba water extracts will be used as the protection or treatment in chronic inflammation desease like a asthma, stomatitis etc.
