Cyperi Rhizoma (CR), the rhizome of Cyperus rotundus L., exhibits neuroprotective effects in in vitro and in vivo models of neuronal diseases. Nevertheless, no study has aimed at finding the neuroactive constituent(s) of CR. In this study, we identified active compounds in a CR extract (CRE) using bioactivity-guided fractionation. We first compared the anti-oxidative and neuroprotective activities of four fractions and the CRE total extract. Only the ethyl acetate (EA) fraction revealed strong activity, and further isolation from the bioactive EA fraction yielded nine constituents: scirpusin A (1), scirpusin B (2), luteolin (3), 6′-acetyl-3,6-diferuloylsucrose (4), 4′,6′ diacetyl-3,6-diferuloylsucrose (5), p-coumaric acid (6), ferulic acid (7), pinellic acid (8), and fulgidic acid (9). The activities of constituents 1-9 were assessed in terms of anti-oxidative, neuroprotective, anti-inflammatory, and anti-amyloid-β activities. Constituents 1, 2, and 3 exhibited strong activities; constituents 1 and 2 were characterized for the first time in this study. These results provide evidence for the value of CRE as a source of multi-functional neuroprotectants, and constituents 1 and 2 may represent new candidates for further development in therapeutic use against neurodegenerative diseases.

Lipid-lowering and antioxidant activities of a hydroalcoholic extract of Cyperus scariosus Linn. root (HCS) were evaluated in guinea pigs fed with a high cholesterol diet. Serum lipid profile (total cholesterol, triglycerides, LDL-C, VLDL-C, and HDL-C), atherogenic indices and serum enzymes (ALT, AST, ALP, LDH, and CK-MB) were performed in each group at 0 days and at the end of 60 days. Histological study of liver and kidney was done in groups 1, 2, 5, 6 and 7. The total phenolic and flavonoid content in HCS and its antioxidant activity were evaluated by the DPPH assay. Both doses of HCS decreased serum lipid profile and atherogenic indices (P < 0.05). HCS has lipid lowering, immunosuppressive and antioxidant properties, and mays have value in atherosclerosis prevention. The higher dose of HCS also reduced serum AST, ALP, and LDH levels and rosuvastatin increased AST and ALP levels (P < 0.05). Histology of the liver showed decreased lipid accumulation and improvement in hepatocytes in HCS-treated animals. The antioxidant activity of HCS may be responsible for its lipid lowering and cytoprotective action. HCS had significant lipid lowering and antioxidant activity, which; may be due to the phenolic compounds. HCS may be a safe and cost effective alternative to current statin therapy for patients with dyslipidaemia.

In a large number of a1lergic cases, inhalant allergens, particularly airborne pollens and mo1ds am important causative, triggering agents in respiratory, even in skinanergy. It is essential for diagnosis and treatment of airborne allergy to survey the airborne pollen and mo1d in the patient's living area. Rotorod samp1er was installed on the well-ventilated rooftop of Hanyang Kuri Hospital in Kuri-shi, Kyunggi-do as the vicinity of Seoul. Airborne allergens were collected from October 1, 1995 to September 30, 1996 daily and were stained with Calberla`s fuchsin and were identified, counted under the light microscope (400Xfor pollen, 1000Xfor mold). The data were compared with the local daily weather report. The airborne pollen was found from 12th February to 22nd December. The maximal period for pollen collection was 7th-25th May (Maximal count:492 grains/ August. There were Alnus, Betula, Pinus, Quercus, Acer, Ulmus, PopuluS, Cupressaceae, Ginkgo, Corylus, Salk in the tree season from middle of February to middle of July. The grass season ranged from middle of March to end of November. There were Artemisia, Ambrosia, HumuluS, Chenopodium-Amaranthus, rumex, Plantago, Trifoium, Humulus, Chrysanthemum, Cyperus in the weed season ranged from middle of July to end of December. Airborne molds were collected all through the year except JanuaIgamma but, counted maximally from the middle of June to end l August. There were CladosPorium, Alternaria, ascospore of Leptospheria, Periconia, Myxomycete, Drechs1era, Rust urediniospores, Basidiospore, ToruIa, Xylariaceae, IOidimn, Nigrospom, Stempi1y1ium, Amphispheda, Fusarium, Aspergil1us. In Korea, there are great number of the allergic patients, but we have had a little records and data about study of relationship between the allergic diseases and airborne environmental allergens. we will reported those results completely in future.

OBJECTIVETo evaluate the pre-clinical effect of YJ-XCC1Z3 on the treatment of depression with the mice mouse.

METHODYJ-XCC1Z3 was administered at the dose of 405 mg x kg(-1) and 135 mg x kg(-1) to observe the locomotor activity with the mouse locomotor activity recorder apparatus, to observe the effect of YJ-XCC1Z3 on the duration of immohility in the mouse forced swimming test and tail suspension test, to observe the effect of YJ-XCC1Z3 on the body temperature and the metabolism of monoamine neurotransmitters in mouse brain in the mouse model of reserpine induced hypothermia, and to observe the effect of YJ-XCC1 Z3 on the times of 5-HTP induced head-twitches in mice.

RESULTThere were no significant changes in the locomotor activity, but a significant reduction in the immobility time was observed in the mice treated with YJ-XCC1Z3 405 mg x kg(-1) and imipramine in the forced swimming test and the tail suspension test. YJ-XCC1Z3 135 mg x kg(-1) and 405 mg x kg(-1) could improve the range of reserpine induced hypothermia in mice, and the latter could also enhance the times of 5-HTP induced head-twitches in mice. YJ-XCC1Z3 405 mg x kg(-1) and 135 mg x kg(-1) could increase the content of 5-HT and NE and decrease the ratio of 5-HIAA/5-HT in mouse brain, but the dose of 405 mg x kg(-1) could decrease the content of DA. The dose of 405 mg x kg(-1) could increase the content of 5-HIAA and had no obvious effect on the content of HVA and DOPAC.

CONCLUSIONYJ-XCC1Z3 shows potent antidepressant effect by improving the behaviour of the mouse in depression and not inducing hyperlocomotion in the mice. This effect results in the increase of the content of 5-HT and NE in the mouse brain. YJ-XCC1Z3 can decrease the metabolism of 5-HT to effect the content of 5-HT.
