Objectives : The effect of mixture extracted from Bupleuri Radix and Physalidis Herba(BR+RH) on the LPS-induced Depression in rats was investigated. Methods : Rats were administered intragastrically BR+PH after injectio of LPS to induce deprssion. Immobility was examined using Tail Suspension Test(TST), Forced Swimming Test(FST). The level of plasma corticosterone was measured by an Enzyme-Linked Immunosorbent Assay(ELISA) method. The expressions of c-Fos, Corticotropin Releasing Factor(CRF), NADPH-d in the Paraventricular nucleus(PVN) and TH in the Locus coeruleus(LC) were measured by immunohistochemical method. Results : In the effect of BR + PH on TST, immobility was significantly decreased comparing with the LPS group. In FST, immobility was shown decrease tendency in the BR+PH group. The expression of c-Fos in the PVN was significantly decreased at BR + PH400 group, comparing with the LPS group. The expression of CRF in PVN was shown dto have the decrease tendency in the BR+PH group, comparing with the LPS group. The expression of NADPH-d in PVN was not significantly decreased at BR+PH groups, comparing with the LPS group. The expression of TH in the LC was shown to have the decrease tendency at BR + RH groups, but not significantly, comparing with the LPS group. Conclusions : Anti-depressant effect of mixture after extracted from Bupleuri Radix and Physalidis Herba was through the anti-inflammatory effect via inhibition of HPA axis. NO and catecholamine system is not involved.

The object of this study was to evaluate the effect of Bupleuri Radix, aqueous extracts of the root part of Bupleurum falcatum on the 6-n-propyl-2-thiouracil (PTU)-induced rat hypothyroidism. Aqueous extracts of Bupleuri Radix (BR; yield = 11.73%) were administered, once day for 42 days from 2 weeks before start of PTU treatment as an oral dose of 300 and 150 mg/kg (body weight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. The changes on the body weight, thyroid gland weights, serum thyroid hormone - thyroid stimulating hormone (TSH), triiodothyronine ($T_3$) and thyroxine ($T_4$), serum lipid profiles - total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL) and triglyceride, liver antioxidant defense system - lipid peroxidation, $H_2O_2$, superoxide dismutase (SOD) and catalase (CAT), serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were observed with histopathology of thyroid glands. Results were compared with $LevoT_4$ 0.5 mg/kg treated rats. As results of PTU treatment, marked decreases of body weights, triglyceride contents, liver CAT activities and changes of serum thyroid hormone levels were observed with increases of serum AST, HDL contents, liver $H_2O_2$ and SOD activities and thyroid gland weight. In addition, marked hyperplasia of follicular cells with decreases of follicular colloid contents and sizes were demonstrated at histopathological inspections. However, these PTU induced hypothyroidism were dose-dependently inhibited by treatment of BR extracts, and BR extracts effectively regulated the hypothyroidism related changes on the antioxidant defense system. The results obtained in this study suggest that BR extracts have favorable effects on the thyroid hormone productions with beneficial effects on the hypothyroidism mediated by the modulatory effects on the antioxidant defense system.

In order to prove the antitumer effect of Bupleuri Radix(BR) and Artemisiae capillaris Herba(ACH) experimently, studies were done. The antitumer effect against hepatic cancer such as Hep G2, PLC & Hep 313, and also th synergastic action was evaulatcd in the combined treatment with anticancer drugs using chiefly for liver cancer, such as mitomycin(MMC), cisplatin(CPT) and 5-fluorouracil(5-FU). The results were obtained as follows: 1. IC50 against Hep G2, Hep 3B and PLC was 15.5ug/ml, 25.4ug/ml, 31.25ug/ml in Mitomycin (MMC), 92.5ug/ml, 50.2ug/ml, 62.5ug/ml in cisplatin(CPT) and 125ug/ml in 5-fluouracil(5- FU) respectively. 2. The antitumor effect was shown in the all concentrations of ACH, BR and below 55%-Cytotoxic effect against Hep G2 as compared with the date of control was shown in the concentration of $10^{-4}g/ml$ above of BR but not in ACH and also BR and ACHI revealed the synergistic effect with MMC. 3. The antitumor effect was shown in the concentration of $10^{-5}g/ml$ above of ACH, BR and below 55%-Cytotoxic effect against Hep 3B as compared with the data of control was shown in the concentration of $10^{-5}g/ml$ above of ACH but not in BH and also BR & ACH revealed the svnergistic effect with MMC. 4. The antitumor effect was shown in the all concentrations of ACH, BR and 55%-Cytotoxic effect against PLC as compared with the data of control was shown in the concentration of $10^{-5}g/ml$ above of ACH but not in BR and also ACH revealed the synergistic effect with MMC. From the above results it was concluded that Artemisiae capillaris had antitumor effect against PLC, Hep 3B, Bupleuri Radix against Hep G2 and also MMC showed the most synergistic effect in the anticancer drugs.

Objective : This study aimed to assess the preventive effect of Bupleuri Radix aqueous extracts (BR) and red koji-fermented BR (fBR) in lipopolysaccharide (LPS)-induced acute lung injury in a rat model. Methods : Rats were administered 30, 60, or 120 mg/kg/day of fBR for 28 days before LPS treatments. All rats were sacrificed 5 h after LPS treatment (500 ㎍/head, intratracheal instillation). Body weights, lung weights, pulmonary transcapillary albumin transit, arterial gas parameters (pH, partial pressure [Pa] of O2, PaCO2), bronchoalveolar lavage fluid (BALF) protein, lactate dehydrogenase (LDH), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), total cell numbers, neutrophil/alveolar macrophage ratios, lung malondialdehyde (MDA), and myeloperoxidase (MPO) were measured. In addition, histopathological changes including the luminal surface of alveoli (LSA), thickness of alveolar septum, and number of polymorphonuclear neutrophils (PMNs) were checked. Results : LPS injection led to increases in lung weights, pulmonary transcapillary albumin transit, BALF protein, LDH, TNF-α and IL-1β contents, total cells, neutrophil and alveolar macrophage ratios, lung MDA, MPO, alveolar septum thickness, and PMNs, and decreases in PaCO2 and pH of arterial blood and LSA. However, these LPS-induced acute lung injuries were inhibited by pretreatment of 30, 60, and 120 mg/kg of fBR. The most favorable effects were seen with 30 mg/kg fBR as compared with 60 mg/kg of α-lipoic acid and BR. Conclusions : fBR showed preventive effects on LPS-induced acute lung injury, which resembles acute respiratory distress syndrome. The mechanisms of action were likely via antioxidant and anti-inflammatory means.

This research was performed in order to investigate the anti-inflammatory effects of Bupleuri Radix(BR) on the Immune response in vitro. Cellular proliferation and cytokine production were measured in mast cells or mouse B cells or CD4 Th cells. BR water extract inhibited the secretions of TNF-$\alpha$ and IL-6 in PMA/A23187 stimulated HMC-1 cells. It increased proliferation but did not affect the expressions of CD69 or CD23 in rIL-4/anti-CD40 activated S cells. BR reduced surface IgE expression and secreted IgE but increased the production of IL-4, IFN-$\gamma$ and IgG1 in the same cells. BR caused an increase in proliferation in anti-CD3/anti-CD28 stimulated CD4 Th cells but it did not affect the differentiation of Th1 or Th2 cells. However, IL-2 was increased in BR treated Th2 cells. Considering the above-mentioned results, BR can be applied to a broad range of anti-inflammatory reactions, but our data suggest that it will not be likely to exert any effects on type 1 allergic response.

The aim of this study was to evaluate the single oral dose toxicity of Bupleuri Radix (BR) aqueous extracts, it has been traditionally used as anti-inflammatory agent, in male and female mice. BR extracts (yield = 16.52%) was administered to female and male ICR mice as an oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration (KFDA) Guidelines. Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation during 14 days after dosing, upon necropsy; organ weight and histopathology of 14 principal organs were examined. As the results, no BR extracts treatment related mortalities, clinical signs, changes on the body and organ weights, gross and histopathological observations against 14 principal organs were detected up to 2,000 mg/kg in both female and male mice, except for soft feces and related body weight decrease detected in male mice treated with 2,000 mg/kg. Therefore, $LD_{50}$ (50% lethal dose) and approximate LD of BR aqueous extracts after single oral treatment in female and male mice were considered over 2000 mg/kg, respectively. Although it was also observed that the possibilities of digestive disorders, like soft feces when administered over 2,000 mg/kg of BR extracts in the present study, these possibilities of digestive disorders can be disregard in clinical use because they are transient in the highest dosages male only.

In this research, the genotoxic effect of Bupleuri Radix (BR), the dried roots of Bupleurum falcatum Linne has been traditionally used as anti-inflammatory agent, was evaluated using the mouse micronucleus test. BR aqueous extract (yield = 16.52%) was administered once a day for 2 continuous days by oral gavage to male ICR mice at doses of 2,000, 1,000 and 500 mg/kg. Cyclophosphamide (CPA) 70 mg/kg was used as a known genotoxic agent in a positive control. The appearance of a micronucleus (MN) in polychromatic erythrocyte (PCE) is used as an index for genotoxic potential, and PCE ratio is used as an index of cytotoxicity. Although significant (p<0.01) increase of the number of PCE with one or more nuclei (MNPCE) was detected in CPA treated groups, no significant increases of MNPCE numbers were observed in all three different dosages of BR extracts treated mice with over 0.30 of the individual polychromatic erythrocyte ratio in all mice used in this study. The results obtained indicated that BR extract shows no genotoxicity effects up to 2,000 mg/kg dosing levels the limit dosage in rodents.
