  • Objectives : It has been reported that Sophorae Subprostratae Radix (SSR) has a neuroprotective effect on cerebral ischemia in animals. In the present study, the authors investigated the neuroprotective effect of SSR on glutamate excitotoxicity. Glutamate excitotoxicity was induced by using NMDA, AMPA, and KA in PC12 cells and in organotypic hippocampal slice cultures. Methods :Methanolic extract of SSR was added at 0.5, 5, and 50 ${\mu}$g/ml to culture media for 24 hours. The effects of SSR were evaluated by measuring of cell viability, PI-stained neuronal cell death, TUNEL-positive cells, and MAP-2 immunoreactivity. Results : SSR increased PC12 cell viabilities significantly against AMPA-induced excitotoxicity, but not against NMDA-induced or KA-induced excitotoxicity. In organotypic hippocampal slice cultures damaged by NMDA-induced excitotoxicity, SSR attenuated neuronal cell death significantly in the CA1, CA3, and DG hippocampal regions and reduced TUNEL-positive cells significantly in CA1 and DG regions. In organotypic hippocampal slice cultures damaged by AMPA-induced excitotoxicity, SSR attenuated neuronal cell death and reduced TUNEL-positive cell numbers significantly in the CA1 and DG regions. In organotypic hippocampal slice cultures damaged by KA-induced excitotoxicity, SSR attenuated neuronal cell death significantly in CA3, but did not reduce TUNEL-positive cell numbers in CA1, CA3 or DG. In organotypic hippocampal slice cultures damaged by NMDA-induced excitotoxicity, SSR attenuated pyramidal neuron neurite retraction and degeneration in CA1. Conclusions : These results suggest that the neuroprotective effects of SSR are related to antagonistic effects on the NMDA and AMPA receptors of neuronal cells damaged by excitotoxicity and ischemia.

  • Objectives : The purpose of this study is to investigate the effects of Sophorae radix pharmacopuncture(SRP) therapy on the Chunchu($ST_{25}$) on intestinal disease in rats with dextran sulfate sodium(DSS)-induced colitis. Methods : The experimental model of colitis was induced by an infection of DSS for fifteen days. After colitis was induced, SRP therapy was practiced on the Chunchu($ST_{25}$) once every three days for a total of five times. Afterward, colon length, damage to the colonic mucosa, complete blood count, aspartate aminotransferase(AST), alanine transferase(ALT), blood urea nitrogen(BUN), creatinine, TNF-${\alpha}$ and IL-6 were measured. Results : The results were obtained as below. 1. Colon length was significantly increased in the SRP group 2 compared to the control group. 2. Damage of colonic mucosa was observed less in the SRP groups than in the other groups. 3. The mean rates of white blood cell(WBC), neutrophils and lymphocytes were significantly increased in SRP group 2 compared to the control group. 4. The mean rates of HGB and hematocrit(HCT) were significantly increased in the SRP compared to the control group. 5. No significant differences were shown in AST, ALT, BUN and Creatinine between the SRP groups and the control group. 6. The mean rate of TNF-${\alpha}$ was significantly decreased in the SRP groups compared to the control group. 7. The mean of IL-6 was significantly decreased in the SRP groups compared to the control group. Conclusions : These results indicated that SRP therapy on Chunchu($ST_{25}$) functions as a treatment to the dextran sulfate sodium-induced colitis.

  • Phytoestrogens have been used as a food supplement to prevent osteoporosis. The isoflavones in the phytoestrogens are daidzein, genistein and formononetin which are present in various herbs. This study examined the quantity of isoflavones in medicinal herbs, which can be used as a phytoestrogen supplement; soybean. These isoflavones were quantified using high performance liquid chromatography (HPLC) with a UV/VIS detector. The concentration of daidzein in Puerariae Radix was $10,436.16{\pm}2,143.83\;mg/kg$ of the dried herb, which was much higher than that extracted from soybeans, $341.47{\pm}18.96\;mg/kg$. The amount of genistein in Sophorae flavescentis Radix ($336.09{\pm}50.89mg/kg$) was approximately 11 times higher than that extracted from soybean ($30.03{\pm}7.17mg/kg$). The level of formononetin in Dalbergiae odoriferae Lignum, $2,189.14{\pm}136.46mg/kg$, was the highest among the herbs tested. The total isoflavone content of Puerariae Radix was approximately 30 times higher than that extracted from soybean. Therefore, plants from the family Leguminosae, particularly Puerariae Radix, can be a good source of phytoestrogens.

  • Atopic dermatitis is frequently encountered in the Dermatology clinic and the treatments are very various but the effects are not good enough. Especially in case of infants, taking herb med or acupuncture treatments are difficult so we would like to treat the atopic dermatitis using external therapy. We chose the oriental medicine textbooks and the oriental medicine journals that external therapy was used and divided into Yugobub(油膏法), Buchubbub(敷貼法), Sechukbub(洗滌法). The results were as follows: 1. In the frequency of medicine was Coptidis Rhizoma(黃連), Phellodendri Cortex(黃栢), Sophorae Radix(苦蔘), Cnidii Fructus(蛇床子), Allumen(枯礬) etc. 2. The effects of medicine were Chungyul(淸熱), Haedok(解毒), Zosub(燥濕), salchung(殺蟲), Gupung(祛風), Jiyang(止痒) etc.

  • Twenty seven plant extracts were selected on the basis of ancient literature search for rheurnatoid arthritis or similar syndrome. Methanol extract of each plant was prepared and administered orally to rats everyday at a dose of 200 mg/kg/day. Experimental arthritis was induced by subplantar injection of heat-killed Mycobacterium butyricum to right hind paw of rats. This treatment provoked swelling of the treated paw in two phases, acute primary swelling and secondary arthritic swelling. An inhibition of secondary swelling was considered to be antiarthritic activity. Several plant methanol extracts such as Akebia quinata (caulis), Ephedla sinica (herba) and 5ophorae subprostratd (radix) were found to show significant inhibitory activity against secondary swelling at the dose tested. Our results strongly suggested an antiarthritic potential of these plant extracts.

  • Leukotriene $B_4\;(LTB_4)$ is a pro-inflammatory mediator synthesized in myeloid cells from arachidonic acid. Elevated levels of $LTB_4$ have been found in a number of inflammatory diseases and levels are related to disease activity in some of these. Because $LTB_4$ interacts with cells through specific cell surface receptors, $LTB_4$ receptor blockade is the most specific approach to reduce the pathogenic role of $LTB_4$. In order to find $LTB_4$ receptor antagonist from plants, we screened the $LTB_4$ receptor antagonistic activity of the methanol extract and solvent fractions of herbal drugs. The ability of samples to inhibit specific binding of $[^3H]-LTB_4$ to human peripheral neutrophils was used as assay to evaluate the antagonistic activity of plant materials. Among the tested methanol extracts of herbal drugs, Mori Radicis Cortex, Perillae Semen, Armeniacae Semen and Sophorae subprostratae Radix showed potent inhibitory activity above 70% at the concentration of $100\;{mu}g/ml$. The inhibitory activities of $LTB_4$ binding to human neutrophils were evaluated for several solvent fractions at three different concentrations. Especially, hexane soluble fractions of Anemarrhenae Rhizoma and Embeliae Radix, and ethyl acetate soluble fractions of Aristolochiae Fructus, Magnoliae Cortex and Zingiberis Rhizoma crudus showed moderate activity at $25\;{mu}g/ml$. These fractions were promising candidates for the study of the activity-guided chromatographic purification of active compounds. Silica gel column chromatography of hexane soluble fractions of Anemarrhenae Rhizoma and Embeliae Radix gave very active sub-fractions, AA-4 and ES-4, and their inhibition activities of $LTB_4$ binding to human neutrophil at $30\;{mu}g/ml$ were 78% and 62%, respectively. From these results we could anticipate new $LTB_4$ receptor antagonist from herbal drugs, and the block of $LTB_4$ effects may provide beneficial in neutrophil mediated diseases such as inflammation and bronchial asthma.
