Objective: This study was conducted to investigate the effects of Aconiti Tuber on the plasma IL-6 and $TNF-{\alpha}$ level in mice stimulated by intracerebroventricular(I.C.V.) Injection of Lipopolysaccharide(LPS). Method: 6 mice were assigned to each of the normal group, the control group, and the experimental group. In the normal group only saline was administered intragastrically, and in the control group LPS was injected intracerebro-ventricularly 1 hr after intragastric administration of saline. In the experimental groups (Aconiti Tuber 0.5g/kg, Aconiti Tuber 1.0g/kg, Aconiti Tuber 3.0g/kg) each sample was administered intragastrically to mice 1 hr prior to the stimulation by LPS I.C.V. Injection. To measure the plasma IL-6 and $TNF-{\alpha}$ level of mice, their blood samples were collected from retro-orbital plexus, immediately centrifuged at $4^{\circ}C$, and plasma was removed and stored frozen at $-83^{\circ}C$ for later determination of plasma IL-6 and $TNF-{\alpha}$. Result : 1. LPS I.C.V. Injection increased plasma IL-6 level significantly in a dose-dependent manner compared with normal group(P<0.01). The plasma IL-6 concentration reached a significant maximal level about 1 hr after LPS I.C.V. Injection(P<0.001). LPS I.C.V. Injection increased plasma $TNF-{\alpha}$ level significantly in a dose-dependent manner(P<0.05). The plasma $TNF-{\alpha}$ concentration reached a significant maximal level about 1 hr after LPS I.C.V. Injection(P<0.001). 2. Sample A group to which Aconiti Tuber(0.5g/kg) was administered intragastrically 1 hr prior to the stimulation by LPS I.C.V. Injection showed insignificant lower plasma IL-6 level in 1 hr than control group(P<0.0635), and sample B group (Aconiti Tuber 1.0g/kg) showed significant lower plasma IL-6 level in 1 hr than control group(P〈0.05), and sample C group (Aconiti Tuber 3.0g/kg) showed significant lower IL-6 plasma level in 1 hr than control group(P<0.01). 3. sample A group to which Aconiti Tuber(0.5g/kg) was administered intragastrically 1 hr prior to the stimulation by LPS I.C.V. Injection showed insignificant lower plasma $TNF-{\alpha}$ level in 1 hr than control group(P>0.05), and Both sample B(1.0g/kg) and sample C(3.0g/kg) groups showed significant lower $TNF-{\alpha}$ plasma level in 1 hr than control group(P<0.01). These data revealed that Aconiti Tuber might have the anti inflammatory effect by reducing the plasma IL-6 and $TNF-{\alpha}$ level in a dose dependent manner in mice LPS I.C.V. Injection.

1. All the male students and female students who had taken these herb medicines showed a strong increase in immunity (P<0.01) and they were more effective to the male students (P<0.01) rather than the female students (P<0.05) (figure 1). Generally, immunity may be reduced at the time of fatigue and overwork but as these herb medicines have the effect of increasing immunity. Therefore, it is considered that they not only reduce the fatigue of human body but also heighten immunity against disease. 2. The students who had taken these herb medicines showed some reduction in Cortisol concentration in blood, which didn't show the difference of concentration up to statistical meaning compared to before taking the medicines (figure 2). Accordingly, it is regarded that these herb medicine drink restrained stress slightly. 3. The students who had taken these herb medicines showed some reduction in BUN concentration in blood, which didn't show the difference of concentration up to statistical meaning compared to before taking the medicines (figure 3). For the women, they restrained the toxicity of the kidneys just a little. Accordingly, it shows that these medicines are safe herb medicines without the toxicity of the kidneys. 4. The students who had taken these herb medicines didn't show the difference of concentration up to statistical meaning in sFOT and sGPT concentration in blood compared to taking them (figure $4{\sim}5$). Accordingly, it is suggested that these medicines are safe stuffs without the toxity of the liver. 5. Seven members of the university students answered to the questionaire that they were pleasant while taking the medicines and didn't feel fatigue. They answered very positively that they had better effects than before taking the medicines in many things (Refer to the Questionaire). However, one male student and two female students of them complained of temporary headache and indigestion for 2 days after taking these herb medicines but they said they had been taking cold medicines due to cold symptom before taking the medicines. Accordingly, it turns out that such temporary symptom is not irrelevant to these medicines. In conclusion, it is considered that these herb medicines have the effects of increasing immunity, restraining fatigue and stress through this clinical study carried out in simple way and that they are valuable as herb medicines without the toxity of the liver and kidneys.

Objectives : The aim of this study was to evaluate the efficacy of Hwangryunhaedok-tang (HHT) and Gungangbuja-tang (GBT) on lipopolysaccharide (LPS)-induced mouse model of inflammation. HHT and GBT are one of the representative prescriptions of cold drug and one of the representative prescriptions of hot drug, respectively. For experimental evaluation of their efficacy, we investigated the anti-inflammatory effects of HHT and GBT on LPS-induced inflammation and the mechanisms of their action. Methods : ICR mice were given a HHT (50, 500 mg/kg), GBT (100, 1000 mg/kg) extract orally on three consecutive days. On the third day, they were administered LPS intraperitoneally (35 mg/kg), 1 h after the last sample administration. Blood and liver samples were taken 6 h after the LPS challenge. Cytokine expression and inflammation-related protein factor analyses were performed by Western blotting. Results : Oral administration of HHT significantly reduced pro-inflammatory cytokines, including interleukin (IL)-6, and interferon (IFN)-${\gamma}$ in the serum. While GBT inhibited an increase of IL-6, IFN-${\gamma}$ was not affected. Immunoblot analysis showed that LPS-induced NF-${\kappa}b$ activation was inhibited by GBT, meanwhile HHT only inhibited NF-${\kappa}b$ expression at high does (500 mg/kg). In addition, HHT and GBT inhibited LPS-induced phosphorylation of Erk1/2, Jnk and p38 MAPKs. GBT also significantly inhibited i-Nos and Cox-2 expression, and HHT inhibited only i-Nos expression. Conclusions : Both of HHT and GBT showed anti-inflammatory effects against LPS-induced endotoxemia. However, HHT significantly decreased inflammatory cytokine levels, such as IL-6 and IFN-${\gamma}$ more than GBT, while GBT significantly inhibited inflammatory proteins, including NF-${\kappa}b$, MAP Kinases, i-Nos and Cox-2, more than HHT. These results suggest that HHT and GBT regulate the different mechanisms of action and pathways, presumably by regulating cytokine levels (IL-6, IFN-${\gamma}$), NF-${\kappa}b$ activation, and several pro-inflammatory gene expression, although both of HHT and GBT have anti-inflammatory effects.

Objectives : Oxidative stress due to excessive accumulation of reactive oxygen species (ROS) is one of the risk factors for the development of several chronic diseases, including neurodegenerative diseases. Methods : In the present study, we investigated the protective effects of cheongnoemyeongsin-hwan (CNMSH) against oxidative stress‑induced cellular damage and elucidated the underlying mechanisms in neuronal-derived SH-SY5Y cells. Results : Our results revealed that treatment with CNMSH prior to hydrogen peroxide (H2O2) exposure significantly increased the SH-SY5Y cell viability, indicating that the exposure of the SH-SY5Y cells to CNMSH conferred a protective effect against oxidative stress. CNMSH also effectively attenuated H2O2‑induced comet tail formation, and decreased the phosphorylation levels of the histone ${\gamma}H2AX$, as well as the number of apoptotic bodies and Annexin V‑positive cells. In addition, CNMSH exhibited scavenging activity against intracellular ROS generation and restored the mitochondria membrane potential (MMP) loss that were induced by H2O2, suggesting that CNMSH prevents H2O2‑induced DNA damage and cell apoptosis. Moreover, H2O2 enhanced the cleavage of caspase-3 and degradation of poly (ADP-ribose)-polymerase, a typical substrate protein of activated caspase-3, as well as DNA fragmentation; however, these events were almost totally reversed by pretreatment with CNMSH. Furthermore, CNMSH increased the levels of heme oxygenase-1 (HO-1), which is a potent antioxidant enzyme, associated with the induction of nuclear factor-erythroid 2-related factor 2 (Nrf2). According to our data, CNMSH is able to protect SH-SY5Y cells from H2O2-induced apoptosis throughout blocking cellular damage related to oxidative stress through a mechanism that would affect ROS elimination and activating Nrf2/HO-1 signaling pathway. Conclusions : Therefore, we believed that CNMSH may potentially serve as an agent for the treatment and prevention of neurodegenerative diseases caused by oxidative stress.

Objectives : Cheongnoemyeongsin-hwan (CNMSH) is a herb medicine to treat cognitive impairment. This study was investigated the effects of CNMSH on learning and memory impairment induced by cerebral hypoperfusion. Cerebral hypoperfusion was produced chronically by permanent bilateral common carotid artery occlusion (BCCAO) in rats. Methods : CNMSH was administered orally once a day (250 mg/kg) for 28 days starting at 4th week after the BCCAO. The acquisition of learning and the retention of memory were tested on 9th week after the BCCAO using the Morris water maze. In addition, effect of CNMSH on neuronal apoptosis and ${\beta}-amyloid$ accumulation in the hippocmapus was evaluated with immunohistochemistry and Western blotting. Results : 1. CNMSH and ChAL significantly shortened the escape latencies on the 2nd day of acquisition training trials. 2. ChAL significantly prolonged the swimming time spent in the target and peri-target zones and CNMSH also significantly prolonged the swimming time spent in the peri-target zone. 3. CNMSH and ChAL significantly increased the number of target heading in the retention test. 4. ChAL significantly shortened the time of the 1st target heading in the retention test, but CNMSH insignificantly shortened the time of that. 5. CNMSH and ChAL significantly increased the memory score in the retention test. 6. CNMSH and ChAL significantly attenuated the reduction of CA1 neurons, but insignificantly attenuated the reduction of CA1 thickness. 7. CNMSH and ChAL significantly attenuated the up-regulation of Bax expression in the CA1 of hippocampus. 8. CNMSH and ChAL significantly attenuated the up-regulation of cascapse-3 expression in the CA1 of hippocampus. 9. CNMSH and ChAL significantly attenuated the ${\beta}-amyloid$ accumulation in the CA1 of hippocampus. 10. CNMSH and ChAL significantly attenuated the up-regulation of APP expression in the CA1 of hippocampus. 11. CNMSH and ChAL significantly attenuated the up-regulation of BACE-1 expression in the CA1 of hippocampus. Conclusions : The results show that CNMSH attenuates neuronal apoptosis and ${\beta}-amyloid$ accumulation in the hippocampus and alleviates the impairment of learning and memory produced by chronic cerebral hypoperfusion. These results suggest that CNMSH may be a beneficial medicinal herb to treat cognitive impairment associated with neurodegenerative diseases.

Objectives : Present study investigated hepatoprotective effects of four types of Taraxaci Herba water extract (TL-F, Taraxaci Herba leaf originated from foreign country; TR-F, Taraxaci Herba root originated from foreign country; TL-K, Taraxaci Herba leaf originated from Korea; TR-K, Taraxaci Herba root originated from Korea) on carbon tetrachloride (CCl₄)-induced acute liver injury. Methods : Mice were administered orally with 200 mg/kg of TL-F, TR-F, TL-K, or TR-K for seven days, and intraperitoneally injected with 0.5 mL/kg of CCl₄ 1 h after last Taraxaci Herba treatment. Silymarin (100 mg/kg) was used as a positive drug. Body weight gain, relative liver weight, serum biochemistry, histopathological and immunohistochemical analyses, and hepatic antioxidant capacity were determined to investigate the hepatoprotective effect of four extracts. Results : Administration of four types of Taraxaci Herba extract increased body weight gain, and decreased relative liver weight in CCl₄-injected mice. As compared to CCl₄ group, TL-F and TR-F significantly decreased serum aspartate aminotransferase activity, while four extracts reduced CCl₄-induced alanine aminotransferase activity. In addition, TL-F and TR-F significantly decreased the numbers of degenerated hepatocytes, infiltrated inflammatory cells, cleaved caspase-3 positive cells, and cleaved PARP positive cells in hepatic tissues. Moreover, TL-F, TR-F, and TR-K administration reduced the lipid peroxidation and nitrotyrosine, and increased glutathione, superoxide dismutase, and catalase activities in hepatic tissues. There were no statistical differences between TL-F- and silymarin-treated group. Conclusion : Of four extracts tested, present results suggest that TL-F is the most favorable candidate against CCl₄-induced acute liver injury through enhancing antioxidant activity.

From the tuberous root of Aconitum carmichaeli Debx.(Ranunculaceae), the main root is called as common monkhood mother root and the later root is called as the prepared aconite root. From the prepared aconite root. Looking at the processing method of the prepared aconite root, it is divided into Yeombuja (prepared aconite root processed in salt) and heuksoonpyeon (baekbupyeon) following the processing method after removing the soil and this is a way of processing the prepared aconite root without damage it. The recently produced raw prepared aconite root is easily damaged, thus it shall be preserved in salt to have the crystal shape on the surface of the prepared aconite root and store and transport in firmly solidified yeombuja condition. Therefore, yeombuja shall remove the salt before use and requires processing for use but heuksoonpyeon or baekbupyeon may use immediately. For the succession of the unique processing techniques of our ancestors, there has to be studies on the techniques. Prepared aconite root is generally used as holy medicines to cure the yang depletion syndrome, kidney-yang deficiency syndrome, and obstruction of qi in the chest syndrome. However, they are the substances with toxicity. It is contemplated that the contents of processing are broadly understood through the document on the processing method, and based on such foundation, the systematic set and proof on the documents are made along with the addition of the contemporary scientific theory and technology to develop the traditional processing technology to maximize the treatment effect and safety of prepared aconite root.

Herba Artemisiae Capillaris is the dried bud of Artemisia capillaris Thunb, which has been used for expelling heat to loosen the bowels and normalizing gallbladder function to cure jaundice in traditional oriental medicines. In the present study, we evaluated the anti-inflammatory effects of the aqueous extracts of Herba Artemisiae Capillaris (HAC) in LPS-activated Raw 264.7 cells. Cells were treated with $1\;{\mu}g/ml$ of LPS 1 h before adding HAC extract. Cell viability was determined by MTT assay, and the relative level of NO was measured with Griess reagent. TNF-$\alpha$, IL-$1{\beta}$, and IL-6 cytokines were detected by ELISA. During the entire experimental period, all three doses of HAC extract (0.03, 0.10 and 0.30 mg/ml) had no significant cytotoxicity. LPS-activated cells showed increased NO levels and iNOS expressions compared to control. However, these increases were dramatically attenuated by treatment with HAC extract. Moreover, the inhibitory effects of HAC extract occurred in a dose-dependent manner. In addition, HAC extract reduced the translocation of $NF{\kappa}B$ into nuclear. HAC reduced production of IL-$1{\beta}$ and IL-6 by LPS, although it had no effects on TNF-$\alpha$. These results demonstrate that liquiritigenin exerts anti-inflammatory effects, which results from the inhibition of $NF{\kappa}B$ activation in macrophages, thereby decreasing production of iNOS and proinflammatory cytokines. Taken together, these results indicate that the aqueous extracts of Herba Artemisiae Capillaris warrant further development as an anti-inflammatory agent for the treatment of gram-negative bacterial infections.
