High-performance liquid chromatography (HPLC) and capillary electrophoresis (CE) were used to identify five active components in the modified herbal decoction Bo-Yang-Hwan-O-Tang (mBHT), i.e., amygdalin, decursin, paeoniflorin, salvianolic acid B, and calycosin-7-O-${\beta}$-D-glycoside. These components were identified by comparing their retention times and mass spectra with those of reference compounds. The conditions of both analytical methods were optimized and validated. Sufficient separation of target analytes was achieved using a buffer consisting of 40 mM sodium borate and 60 mM sodium dodecylsulfate (SDS) containing 10% methanol (pH 9.5) at 250 nm for CE analysis and gradient elution with a water-methanol mobile phase and ultraviolet (UV) photodiode array detector (DAD) at 250 nm for HPLC analysis. The mBHT components were determined within 65 min by HPLC and 16 min by CE. All calibration curves showed high linearity (R > 0.999) within the ranges tested. Intra-day and inter-day precision were less than 1.6% and 1.8% for HPLC and 2.5% and 4.8% for CE, respectively. The accuracy of the methods ranged from 98.8% to 102.3% for HPLC and from 95.9% to 108.2% for CE.

Stachys tibetica Vatke (Lamiaceae) is an important medicinal plant in the folk medicine of Ladakh, India and Tibet for the treatment of various mental disorders. Infusion and decoction of the whole plant is used as a cup of tea for a severe fever, headaches and to relieve tension. The recent study is aimed to evaluate the preliminary pharmacognostical and phytochemical nature of Stachys tibetica Vatke. The whole plant material was subjected to successive soxhlet extraction with petroleum ether (40 - $60^{\circ}C$), chloroform, ethyl acetate, methanol and finally decocted with water to get the respective extracts. The fluorescence characteristics of the powdered materials were analysed under ultraviolet light and ordinary light. Different physicochemical parameters such as ash value, extractive value, foaming index, pH values, loss on drying and determination of foreign matter were carried out as per WHO guidelines. The total fat, flavonoid, saponin and volatile contents were also determined. Macroscopical studies revealed the authentication of the plant drug. Physicochemical parameters helped to standardize the plant material while preliminary qualitative chemical tests of different extracts showed the presence of Glycosides, Carbohydrates, Phytosterols/triterpenoids, Saponins, Fixed oils, Fats and phenols/tannins. Quantification of the total flavonoids and saponins and contents were determined as $54.66{\pm}0.58mg/g$ and $75.42{\pm}0.48mg/kg$ respectively, while the volatile and fat contents were 6.5% and 0.7% respectively. Results may lay the foundation for the standardization of the drug and discovery of new molecules from S. tibetica for the treatment of various diseases.

Paraquat, one of the potent herbicides, causes fatal damage to many vital organs, when orally ingested, resulting in circulatory failure, respiratory distress syndrome, and a few other serious problems, but there is no known specific antidote against it. Of the possible problems related to paraquat intoxication, oliguric acute renal failure, which has been known to develop within 24 or 48 hours after intoxication, are notoriously life-threatening. So we attempted to investigate the clinical characteristics and progress of paraquat-induced acute renal failure and the therapeutic possibilities of herbal medicines. All of the fifteen subjects were treated with intravenous fluid injection of 5% dextrose saline or 10% dextrose water in conjunction with herbal medicines which were used for oral administration or gargling. Gamdutang, a decoction of Semen Glycin(黑豆 200g) and Radix Glycyrrhizae(甘草 100g) with addition of other herbs when necessary, was administered orally. At the same time, gargling fluid, consisted of Chinese ink(墨汁), char-frying powder of Rhei Rhizoma(大黃炒炭末), Succus phyllostachyos(竹瀝), was used to detoxify the oral cavity. Serum levels of Blood Urea Nitrogen(BUN) and Creatinine reached its peak on the third day of hospitalization, but then decreased and fell within the normal range on the 7th day and remained there. Serum levels of Na+ and K+ decreased down below the lower limits of normal range on the 7th day and on the 3rd day, respectively. Then they returned back within normal limits. Mean urine output on the 1st day of hospitalization was 1,050ml and it continuously increased to reach more than 2,000ml on the 14th day. From that day on, it stayed over 2,000ml. Fifteen cases of acute renal failure caused by paraquat intoxication were treated with combined treatments of oriental and western medicine in our hospital. However, we think that it is necessary to study further about the way to combine oriental and western medicine, to find out a more effective treatment method.

In this study, an ultra-performance liquid chromatography-electrospray ionization-mass spectrometry (UPLC-ESI-MS/MS) method was established for simultaneous determination of the 25 marker components, including chlorogenic acid, gallic acid, oxypaeoniflorin, homogentisic acid, methyl gallate, caffeic acid, 3,4-dihydroxybenzaldehyde, paeoniflorin, albiflorin, liquiritin, nodakenin, ferulic acid, ginsenoside Rg1, liquiritigenin, coumarin, cinnamic acid, benzoylpaeoniflorin, ginsenoside Rb1, cinnamaldehyde, paeonol, glycyrrhizin, 6-gingerol, evodiamine, rutecarpine, and spicatoside A in traditional Korean formula, Onkyung-tang. All analytes were separated on a Waters Acquity UPLC BEH $C_{18}$ analytical column ($2.1{\times}100mm$, $1.7{\mu}m$) at $45^{\circ}C$ using a mobile phase of 0.1% (v/v) formic acid in water and acetonitrile with gradient elution. The MS analysis was carried out using a Waters ACQUITY TQD LC-MS/MS coupled with an electrospray ionization (ESI) source in the positive and negative modes. The flow rate and injection volume were 0.3 mL/min and $2.0{\mu}L$, respectively. The correlation coefficient of all analytes in the test ranges was greater than 0.98. The limits of detection and quantification values of the 25 marker compounds were in the ranges 0.03-19.43 and 0.09-58.29 ng/mL, respectively. As a result, methyl gallate, 3,4-dihydroxybenzaldehyde, evodiamine, and rutecarpine were not detected in this sample and the concentrations of the 21 compounds except for the above 4 compounds were $33.09-3,496.32{\mu}g/g$ in Onkyung-tang decoction. Among these compounds, paeonol was detected at the highest amount as a $3,496.32{\mu}g/g$.

Angelica gigas Nakai (danggui) is a popular herb which has been used as a blood-building decoction for recovery from weakness in the Chinese medicine. Its demand increased in functional foods and pharmaceutical industries. For its hygiene, fumigation has been used, but the use of fumigants are going to be prohibited for food processing. In order to investigate gamma irradiation technique for hygiene of danggui, the immunomodulation activity of danggui after irradiation was examined. The water extract of irradiated danggui showed a strong mitogenic effect on splenocytes in vitro to the same level of lipopolysaccharide (LPS) and phytohemagglutinin (PHA). The effect was not different from that of non-danggui. It was tested whether there was any difference between irradiated and non-irradiated danggui in effects on the secretion of antibodies and graft versus host reaction in vivo. It turned out that intraperitoneal (i.p.) administration of the extract of irradiated danggui for 4 days remarkably increased the number of antibody-secreting cells in mice injected with sheep red blood cells (SRBC). Splenomegaly, due to graft versus host reacton, was also increased after 7 days i.p. administration of the extract of danggui in mice injected with allogeneic splenocytes. In these two in vivo test, the effect were not different from those of non-irradiated danggui. These results indicated that immunomodulation activity of danggui might be preserved after irradiation. In the other experiments (data not shown), the irradiated danggui was stable in active component analysis and safe in genetic toxicity test. In further research, the stability in other physiological activity of irradiated danggui will have to be proved before practical application of irradiation for hygiene.

Objectives : Sunghyangjungki-san(Xingxiangzhengqi-san) is a herb decoction prescribed frequently for stroke patients. The present study investigated neuroprotective effects of Sunghyangjungki-san(Xingxiangzhengqi-san) against the ischemic damage of the rat brain. Neuronal cell death under the cerebral ischemia is distinguished with the delayed cell death through apoptosis. Consequently, the effects of Sunghyangjungki-san(Xingxiangzhengqi-san) was evaluated with Bax and Bcl-2 expressions as apoptosis related factors in the brain tissues. Methods : The ischemic damage was induced by the middle cerebral artery occlusion(MCAO) method in Sprague-Dawley rats. Water extract of Sunghyangjungki-san(Xingxiangzhengqi-san) was treated for 5 days after the MCAO. Neurological scores and infarct size with TTC were measured. Bax and Bcl-2 expressions in the brain tissues were observed with immunohistochemistry. Results : Sunghyangjungki-san(Xingxiangzhengqi-san) treatment improved neurological score significantly at 5 days after the MCAO. Sunghyangjungki-san(Xingxiangzhengqi-san) treatment decreased infarct size by the MCAO, but it was not significant statistically. Sunghyangjungki-san(Xingxiangzhengqi-san) treatment attenuated Bax positive neurons significantly in the cerebral penumbra and the caudate putamen. Bcl-2 positive neurons were increased, but not significant. Sunghyangjungki-san(Xingxiangzhengqi-san) treatment increased Bcl-2/Bax expression ratios significantly in the cerebral penumbra and the caudate putamen. Conclusions : These results suggest that Sunghyangjungki-san(Xingxiangzhengqi-san) has a neuroprotective effect on the stroke with modulation of apoptosis related factors.

Objects : In this study, I aimed to determine the size and administration Method of pills preparation in Treatise on Cold Damage Diseases. Methods : I investigated the Treatise on Cold Damage Diseases, Newly Revised Materia Medica, Variorum of the Classic of Materia Medica, The Korean Herbal Pharmacopoeia, and recent studies. Results : There were four kinds of pills preparation. Each size of pill preparation was equal to the Odongja, Tanwhan, Yolk, and quarter of daily dosage of Decoction. One pill of Tanwhan was equivalent to 16 pills of Odongja, and one Yolk was equal to 40 pills of Odongja. The Diameter of Odongja was 6.5 mm, Tanwhan was 16.37897 mm, and Yolk was 22.11484 mm. Jeodangwhan was equal to one quarter daily dosage of Jeodangtang. Maximum size to swallow with water was Odongja and daily dosage, which was 16 pills, includes one square-inch-spoon of powder preparation. When we made the pill preparation, it is difficult to make 16 pills using one square-inch-spoon of powder. Therefore, Zhang Zhongjing made one dosage started from 10 pills to 20 pills to find out optimum dose. Due to the difficulty of making precise size of pills and considerable amount of daily dosage, there was no smaller size than Odongja. When the size of Pill preparation was larger than Odongja, it was ground or boiled slightly to make suspensions. Conclusions : These results suggest that the sizes of Pill preparation in the Treatise on Cold Damage Diseases were true compared with reality.

Ganghwaljetongyeum (GHJTY) is a complex herbal decoction comprising 18 plants; it is used to treat arthritis. In order to develop a new anti-arthritic herbal medication, we selected 5 out of 18 GHJTY plants by using bioinformatics analysis. The new medication, called ChondroT, comprised water extracts of Osterici Radix, Lonicerae Folium, Angelicae Gigantis Radix, Clematidis Radix, and Phellodendri Cortex. This study was designed to investigate its chondroprotective and anti-inflammatory effects to develop an anti-arthritic herb medicine. ChondroT was validated using a convenient and accurate high-performance liquid chromatography. photodiode array (HPLC-PDA) detection method for simultaneous determination of its seven reference components. The concentrations of the seven marker constituents were in the range of 0.81-5.46 mg/g. The chondroprotective effects were evaluated based on SW1353 chondrocytes and matrix metalloproteinase 1 (MMP1) expression. In addition, the anti-inflammatory effects of ChondroT were studied by Western blotting of pro-inflammatory enzymes and by enzyme-linked immunosorbent assay (ELISA) of inflammatory mediators in lipopolysaccharides (LPS)-induced RAW264.7 cells. ChondroT enhanced the growth of SW1353 chondrocytes and also significantly inhibited IL-1β-induced MMP-1 expression. However, ChondroT did not show any effects on the growth of HeLa and RAW264.7 cells. The expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) was induced by LPS in RAW264.7 cells, which was significantly decreased by pre-treatment with ChondroT. In addition, ChondroT reduced the activation of NF-κB and production of inflammatory mediators, such as IL-1β, IL-6, PGE2, and nitric oxide (NO) in LPS-induced RAW264.7 cells. These results show that ChondroT exerted a chondroprotective effect and demonstrated multi-target mechanisms related to inflammation and arthritis. In addition, the suppressive effect was greater than that exhibited by GHJTY, suggesting that ChondroT, a new complex herbal medication, has therapeutic potential for the treatment of arthritis.

In the recent, increased concern has been focused on the pharmacology and clinical utility of herbal extracts and derivatives as a drug or adjunct to chemotherapy and immunotherapy. Salicis Radicis Cortex, A decoction has been mainly used for improvement of ozena and a diuretic effect in oriental medicine, but there was no study on the molecular mechanism of Salicis Radicis Cortex as an immunomodulator. Here we investigated the role of the aqueous extract of Salicis Radicis Cortex in the expression of inflammatory mediators, surface molecule, and related receptors in vitro and in vivo. In murine macrophage RAW 264.7 cells and peritoneal macrophages of C57BL/6N mice, water extract of Salicis Radicis Cortex increased the production of secretary TNF-alpha and Nitric oxide, and the expression level of CD14, LPS co-receptor and CD86, co-stimulatory molecule compared to negative natural extract ex vivo. Moreover, i.p. injection of water extract of Salicis Radicis Cortex significantly increased the secretion level of IFN-gamma and TNF-alpha, IL-2, IL-4 and IL-5 in serum of mice in vivo. Taken together, these results suggest that Salicis Radicis Cortex may regulate the immune response by secreting Th1 and Th2 types of cytokines in vivo and the possibility of its as natural immunostimulator.
