Tumor necrosis factor-alpha (TNF-${\alpha}$) is a major mediator of immuno-inflammatory activity. The purpose of this study is to investigate whether TNF-${\alpha}$ productions of mouse macrophage RAW 264.7 and human hepatocyte HepG2 are modulated by Artemisiae argi Folium water extract (AW), Lactobacillus pentosus-fermented Artemisiae argi Folium water extract (AFL), and Saccharomyces cerevisiae-fermented Artemisiae argi Folium water extract (AFS) for 3 h of incubation. Effect of AW on cell viability of HepG2 was also investigated. TNF-${\alpha}$ productions were measured by Enzyme-Linked Immnunosorbent Assay method and cell viability was measured by MTT assay. Both AFL and AFS significantly increased TNF-${\alpha}$ productions of RAW 264.7 at the concentration of 50, 100, and 200 ${\mu}g$/mL (p<0.05). Also, AFL and AFS significantly increased TNF-${\alpha}$ productions of HepG2 at the concentration of 50, 100, and 200 ${\mu}g$/mL (p<0.05). AW significantly increased TNF-${\alpha}$ production of HepG2 at the concentration of 100 and 200 ${\mu}g$/mL (p<0.05). AW did not show any cytotoxicity on HepG2 cells for 3 h. These results suggest that AFL, AFS, and AW have the immune-enhancing property related with its increasing effect on TNF-${\alpha}$ production of macrophage and hepatocyte.

The mulberry tree (Morus alba L.) has been traditionally used in Chinese medicine to treat inflammatory diseases. We investigated the effects of bioconversion on different components of the mulberry tree, and determined changes in the physiological activities. Ethyl acetate-soluble fractions of five different segments (fruit, Mori Fructus; leaf, Mori Folium; twig, Mori Ramulus; root, Mori Cortex; and mistletoe, Loranthi Ramulus) of the mulberry tree show enhanced anti-oxidant effects in the 2,2-diphenyl-1-picrylhydrazyl, and 2,2'-azinobis-(3-ethylvenzothiazoline-6-sulfonic acid) assays, and enhanced anti-inflammatory effects of lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production in RAW 264.7 macrophages, after being treated with a crude enzyme extract from Aspergillus kawachii, in the following order of activity: Mori Folium>Mori Cortex>Mori Ramulus>Mori Fructus>Loranthi Ramulus. Ethyl acetate- soluble fraction of mulberry leaves (Mori Folium) that underwent bioconversion was most effective, and was devoid of any cytotoxicity. The fraction was also effective against mRNA expression of LPS-induced pro-inflammatory cytokines, such as inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis $factor-{\alpha}$, $interleukin-1{\beta}$, and interleukin-6. In addition, the fraction was effective in LPS-induced phosphorylation of mitogen-activated protein kinases and IKK, and $I{\kappa}B$ degradation, followed by translocation of the nuclear $factor-{\kappa}B$ from the cytoplasm to the nucleus. Thus, bioconversion increased the anti-oxidative and anti-inflammatory activities of the mulberry leaf.

Objectives This study was conducted to observe physiological changes when the function of spleen was extremely deteriorated, and to make an animal model with spleen deficiency. Methods The Normal group (Nr group) was not administered with Senna Folium extract. The SFE group(Senna Folium extract group) was administered with Senna Folium extract every day for the first 2 weeks and then every other day for another week. And the SFE_G group(Senna Folium extract_Ginseng group) was also administered with Senna Folium for 3weeks like the SFE group and fed with ginseng in the third week. Results The score of spleen deficiency was significantly higher in SFE group than in the Nr group and significantly lower in the SFE_G group than in the SFE group. The total weight gain was significantly lower in the SFE group than in the Nr group, and the average daily weight gain was significantly lower in the SFE group than in the Nr group. The difference in stool weight before and after the process of drying was significantly higher in the SFE group than in the Nr group, and significantly lower in the SFE-G group than the SFE group. There was no significant difference in the outcomes related to cold and heat among the three groups. Conclusions Through this study, the animal model with spleen deficiency was developed to prepare a stepping stone for animal tests to verify the efficacy and safety of constitutional prescriptions.

Objectives : This study was designed to investigate the effects of extruded Acanthopanax Folium extracts on Complete Freund's Adjuvant (CFA) induced arthritis of rats. Methods： To induce arthritis in the ankle joint of rats, CFA was injected in the proximal part of the tail subcutaneously. After CFA injection, arthritic conditions were examined with macrography. The volume of paw edema and thickness of the ankle joints were checked regularly within 20 days. At 20 days, histopathological examination was performed on the ankle joint. Inflammation levels were determined by total WBC counts and differential WBC counts using a blood analyzer. Tumor necrosis factor-$\alpha$ and interleukin-1$\beta$ concentration in paw exudate were measured by ELISA method. Results： Several arthritic conditions induced by CFA were alleviated by Acanthopanax Folium treatment. Morphologically, reduction of arthritic conditions were observed and the volume of paw edema and thickness of the ankle joints were significantly decreased. Additionally, cytokines in paw exudate were diminished and histopathological improvement was observed. Conclusions： This study showed that the extruded Acanthopanax Folium extracts have the beneficial effects on the CFA induced arthritis of rats and might be used for chronic arthritis patients.

The purpose of this study is to investigate the effect of water extract from Artemisiae Argi Folium (WAAF) on hydrogen peroxide production within mouse macrophage Raw 264.7 Cells treated with gallic acid, EtOH, LPS, and acetaminophen. WAAF (0${\sim}$400 ug/mL) was treated with gallic acid, EtOH, LPS, acetaminophen. And the intracellular productions of hydrogen peroxide were measured by dihydrorhodamine 123 (DHR) assay. WAAF showed the restoration of the intracellular productions of hydrogen peroxide which were reduced by gallic acid, EtOH, LPS, and acetaminophen in Raw 264.7 Cells. WAAF could be supposed to have the immunological activity related with macrophage's oxidative burst.

Mori Folium(MF) methanol extract and its water soluble fraction showed significant blood glucose lowering effects alloxan-induced hyperglycemic mice. Their hypoglycemic activities seemed to nothing to do with the stimulation of insulin release or insulin-like action, according to our experiments. On the other hand, MF prevents the hyperglycemic responses from an oral load of starch and glucose in vivo. Since complex carbohydrates present in a diet must be degraded to monosaccharides by $\alpha$-glucohydrolase before being absorbed in the gastrointestinal tract, it is thought that blood glucose lowering effects of MF may be related to the inhibition of $\alpha$-glucohydrolase catalyzed enzymatic reaction. In addition, experiments that examined an effect of MF water soluble fraction on gastrointestinal movement showed no significant GI movement inhibitory effect. In conclusion, MF water soluble fraction may possess active component which is a potential candidate as an orally active agent for the treatment of diabetes mellitus.

Effects of hydrogen peroxide$(H_2O_2)$ on polyphenol oxidase (PPO) in Perillae Folium were investigated. The inactivation of this enzyme was dependent on $H_2O_2$ concentration. and the initial lag period was not shown. Preincubation of Perillae Folium PPO with $H_2O_2$ in the absence of a substrate resulted in rapid loss of enzymatic activity. The inactivation of PPO by $H_2O_2$ dependents temperature and pH. OH radical scavengers such as mannitol and sodium formate did not protect the enzyme against inactivation by $H_2O_2$. Substrate analogue such as phenylalanine protected the enzyme against inactivation by $H_2O_2$. and copper chelator such as sodium azide also protected the enzyme.

Objectives : External form and internal intersection of Phragmites communis were observed by the parts of usage (leaves, stems, and roots). Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Results : 1. The intersection of Phragmitis Folium was typically characterized as Gramineae plants, which was perfectly distinguished with Phragmitis Rhizoma and Phragmitis Caulis. 2. The cortex of Phragmitis Rhizoma has a large rectangular pore space, but Phragmitis Caulis does not. Conclusion : Phragmitis Folium, Phragmitis Caulis, and Phragmitis Rhizoma can be distinguished by microscope.
