Objectives : Palmul-tang(Bawu-tang) has been traditionally prescribed a medicine as a restorative. Methods : In this study, we investigated the acute toxicity about water-extracted PalMul-tang(Bawu-tang). Twenty-five mice completed 14 days of oral Palmul-tang(Bawu-tang) at the respective doses of 0(control group), 2560, 3200, 4000 and 5000mg/kg. Results : We observed survival rates, general toxicity, change of body weight, and autopsy. Conclusions : To be confirmed the data for the toxicity and safety problems of oriental medicine prescription. Compared with the control group, we could not find any toxic alteration in all treated groups (2560, 3200, 4000 and 5000mg/kg). In conclusion, LD50 of Palmul-tang(Bawu-tang) was over 5000mg/kg and it is very safe to ICR mice.
Tartary buckwheat has potential as a source of functional food because it contains a number of bioactive compounds such as rutin, catechin and so on. This study was conducted to determine the possibility of development of processed products extracted from sugar-treated sprouts of tartary buckwheat. By using undiluted solution extracted from sprouts of tartary buckwheat, we analyzed their nutrition components and did in vivo experiment to find out pharmaceutical effects. In an experiment using mice, we administered various concentration of buckwheat to induced diabetic mellitus mice for 1 weeks. As a result, the fermented extract from buckwheat sprouts effected finely on lowering blood sugar and decreased LDL-cholesterol and total lipid level but increased HDL-cholesterol level.
1. Objectives This study was designed to andyze the acute toxicity and safety of Yeoldahanso-tang 2.

Results We observed survival rates, general toxicity, change of body weight and autopsy. 4. Conclusions The data confirmed that Yeoldahanso-tang is free from the toxicity and safety problems in oral route respectively. Compared with the control group, we could not find any toxic alteration in all treated groups(2560, 3200, 4000 and 5000 mg/kg). In conclusion, LD50 of Yeoldahanso-tang was over 5000 mg/kg and it is very safe to mice.
Objective : To derive information on the efficacy of Sam-chul-kun-bi-tang (SKT), by evaluating its anti-inflammatory effect. SKT is a widely-used herbal formula in traditional Korean medicine. In many studies, plant-derived anti-inflammatory efficacies have been investigated for their potential inhibitory effects on lipopolysaccharide (LPS)-stimulated macrophages. This study was performed to examine the anti-inflammatory effects of SKT extract on LPS-stimulated RAW 264.7 cells. Methods : The production of nitric oxide (NO), prostaglandin (PG)E2, tumor necrosis factor (TNF)-α and interleukin (IL)-6 were examined in a macrophage cell line, RAW 264.7 cells, in the presence of SKT. RAW 264.7 cells were incubated with LPS 1 μg/mL and SKT for 18 hrs. The anti-inflammatory activity of SKT was investigated by carrageenan-induced paw edema in rats. The paw volume was measured at 2 and 4 hrs following carrageenan-induced paw edema in rats. Results : SKT showed inhibitory effect on PGE2, TNF-α and IL-6 in LPS-stimulated RAW 264.7 cells. But SKT was not inhibitory effect on NO by LPS-stimulated RAW 264.7 cells. Administration of SKT (1 g/kg) also showed a reduction in carrageenan-induced paw edema on rats. Conclusion : These results suggest that SKT has anti-inflammatory activities in both in vitro and in vivo models.
Abstract Stimulation of the Immune Response by Yanggyuksanhwa-tang Da Young Jung, Hyekyung Ha, Ho-Young Lee, Jin-Ah Lee, Nam-Hun Lee, Jun Kyoung Lee, Dae Sun Huang, Hyeun-Kyoo Shin Herbal Medicine EBM Research Center, Korea Institute of Oriental Medicine, Daejeon, 305-811, Korea 1. Objectives Yanggyuksanhwa-tang for Soyangin was applied to investigate the immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses on murine macrophage cell line (RAW 264.7) and ovalbumin/aluminium (OVA/Alum)-immunized mice. 2. Methods This study were carried out in nitric oxide (NO) synthesis on RAW 264.7 cells and cellular proliferation on mouse splenocytes. C57BL/6 mice were immunized intraperitonially with OVA/Alum (100 μg/200 μg) on day 1, 8, and 15. Yanggyuksanhwa-tang was administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured.
Objectives : This study presents a high performance liquid chromatography - electrospray ionization-mass spectrometer (HPLC-MS/MS) methods for the quantitative and qualitative analysis of various active components in Samul-tang, which is composed of four crude herbs. Methods : HPLC-ESI-MS/MS for the determinations of paeoniflorin and 5-HMF (5-hydroxymethyl 2-furaldehyde) in the Samul-tang, the separation method was performed on an COSMOS1L 5C18-AR-Il (2.0 X 150 mm I.D.) column by gradient elution with 0.1% acetic acid and 5% CH3CN in water (A)-0.1% acetic acid and 5% H20 in CH3CN (B) as the mobile phase at a flow-rate of 300 with detection at quadrupole mass spectrometer. The all marker substances were always detected as the base peaks in the positive ion mode. Results : The paeoniflorin of Paeoniae Radix in Samul-tang showed a strong base peak [M+H2O]+ in the positive detection mode to give the following as; paeoniflorin (498.109 [M+H2O]+, 479.8 [M]+, 301 [M-glucose]+, 179.3 [glucose]+). Based on the HPLC retnetion time and MS of standard compounds confirmed the identity of active compounds in Rehmanniae Radix Preparata as follows; 5-HMF (127.0[M+H]+, 109.3 [M-OH]+) in the positive ion mode. Conclusion : According to the above results, HPLC-ESI-MS method permits assignment of tentative structures such as paeoniflorin and 5-HMF in the Samul-tang.
Abstract Safety on Hazardous Substances of Soeumin Kwakhyangjeonggi-san Chang-Seob Seo, Jung-Hoon Kim, Dae-Sun Huang, Hyeun-Kyoo ShinHerbal Medicine EBM Research Center, Korea Institute of Oriental Medicine, Daejeon, 305-811, Korea 1. ObjectiveTo compare the contents and transfer rate of hazardous substances in crude, washing solution, crude after washing, decoction and remnant after boiling.2. MethodsThe heavy metal contents of each step were measured by inductively coupled plasma mass spectrometer (ICP-MS) and mercury analyzer (MA-2). In order to analyze pesticides in each sample we used simultaneous multi-residue analysis of pesticides by GC/ECD, which was followed by GC/MSD analysis to confirm the identity of the detected pesticide in each sample. In addition, the contents of sulfur dioxide (SO2) were performed by Monier-Williams distillation method.3. Results1) Contents (mg/kg) of heavy metals in decoction of all herbal medicine prescriptions were not detected.2) Transfer rates (%) of heavy metals from crude to remnant were As (83.3%), Cd (100.0%), Pb (182.6%) and Hg (100.0%).3) Contents (mg/kg) of residual pesticides were not detected.4) Transfer rate (%) of sulfur dioxide (SO2) from crude to remnant was 44.2%.4. ConclusionOur results showed that boiled herbal medicine prescriptions which we take is safe from the hazardous substances.Key Words:Herbal medicine, Heavy metal, Pesticide, Sulfur dioxide, Soeumin, Kwakhyangjeonggi-san (Huo Xiang Zheng Qi San)

The mean values of heavy metal contents (mg/kg) for the samples were as follows: Sipjeondaebo-tang (before decoction - Pb; 1.163, Cd; 0.257, As; 0.080 and Hg; 0.016, after decoction - Pb; 0.059, Cd; 0.007, As; 0.006 and Hg; 0.0003), Palmul-tang (before decoction - Pb; 1.181, Cd; 0.242, As; 0.152 and Hg; 0.014, after decoction - Pb; 0.067, Cd; 0.008, As; 0.008 and Hg; 0.0003), Sagunja-tang (before decoction - Pb; 1.285, Cd; 0.283, As; 0.063 and Hg; 0.012, after decoction - Pb; 0.047, Cd; 0.009, As; 0.004 and Hg; not detected) and Samul-tang (before decoction - Pb; 1.025, Cd; 0.169, As; 0.099 and Hg; 0.013, after decoction - Pb; 0.065, Cd; 0.007, As; 0.010 and Hg; 0.001). 2. Contents (mg/kg) of residual pesticides before/after a decoction were not detected in any samples. 3. Contents (mg/kg) of sulfur dioxide (SO 2) before a decoction in Sipjeondaebo-tang, Palmul-tang, Sagunja-tang and Samul-tang exhibited 5.0, 6.0, 14.0 and 6.9, respectively. However, contents of sulfur dioxide after a decoction were not detected in any samples. Conclusion: These results will be used to establish a criterion for heavy metals, residual pesticides and sulfur dioxide.
