Purpose: This study was carried out to investigate the anti-tumor metastasis effect and activation of innate immunity by extracts of Mori radicis cortex. Methods: Anti-tumor metastatic experiment was conducted in vitro and in vivo by using colon 26-M3.1 carcinoma cell, L5178Y-R lymphoma cell and HeLa cell. To observe the activation of innate immunity by extracts of Mori radicis cortex, we estimated IL-6, IL-10, IL-12, TNF-${\alpha}$ from peritoneal macrophages. And we evaluated the activation of NK cell by using anti-asialo-GM1 serum. Results: We found that the administration of Mori radicis cortex extracts significantly inhibited tumor metastasis. In an in vitro cytotoxicity analysis, Mori radicis cortex affected tumor cell growth above specific concentration. Mori radicis cortex also stimulated peritoneal macrophage, which was followed by the production of various cytokines such as IL-6, IL-10, IL-12, TNF-${\alpha}$. The depletion of NK cells by anti-asialo GM1 serum partly abolished the inhibitory effect of Mori radicis cortex on tumor metastasis. Conclusion: Mori radicis cortex appears to have considerable activity on the anti-metastasis by activation of innate immunity.

Moraceae comprise a large family of sixty genera and neary 1,400 specieses, including important groups such as Artocarpus, Morus, and Ficus. In particular, Morus(mulberry) is a small genus of tree and shrubs found in temperate and subtropical regions of the Northern hemishere and has been widely cultivated in China and Korea, In addition, the root bark of mulberry tree have been used as an antiphlogic, diuretic, and expectorant in white medicine, and the crude drug is known as "Sangbaikpi" in Korea. Recently, some papers have been published reporting the hypotensive effect, antiviral effect, antifungal effect, inhibitory effect of cAMP-phosphodiesterase, and anticancer effect of this extract. Little is known about that Cortex mori could have been an antiallergic effect. The purpose of this study was the development of an antiallergic agent with an antiallergic effect from Cortex mori. For this, several in vivo and in vitro experimental models were used. Results are 1) Cortex mori inhibited the compound 48/80-induced degranu-lation, histamine release and calcium uptake of rat peritoneal mast cells, 2) compound 48/80-induced anaphylactic shock and cutaneous reaction were significantly inhibited by pretreatment of Cortex mori, and 3) Cortex mori inhibited the ovalbumin-induced late astmatic reaction. From the above results it is suggested that Cortex mori has some substances with an antiallergic activity. Our final purpose of this study is to develope the new drug with an antiallergic activity from Cortex mori

Mori Cortex Radicis, the root bark of mulberry tree, has been used in the treatment of bronchial asthma and other lung diseases in traditional medicine. There was a recent repor t that the water soluble part with molecular weight of above 10,000 has anti-allergic activity. Therefore, we intended to isolate and purify the anti-allergic compound from hot water extract of the Mori Cortex Radicis. Crude extract of Mori Cortex Radicis was prepared by hot-water extraction, and anti-allergic compound was further purified by alcohol precipitation, successive ultrafiltration, anion exchange chromatography and gel filtration chromatography. This compound had homogeneity which was shown by the sharp single peak in HPLC chromatogram (TSK-GEL G400OPW column, RI detector). The molecular weight of the compound was estimated as 23Kda on the basis of calibration curve plotted against protein standards. This compound was identified as complex of sugar, protein and lignin (19.2: 5.9: 72.7), and proteolysis could not decrease the anti-allergic activity but mild delignification decreased the activity remarkably. Therefore, we concluded that the anti-allergic compound of Mori Cortex Radicis was a lignin-carbohydrate complex.

Objective: This experimental study was performed to examine the in vitro and in viva anti-inflammatory and anti-allergic effects of Mori Cortex. Methods: Water extract of Mori Cortex was studied to its ability to stimulate or inhibit macrophage 264.7 cells to produce inflammatory and allergic mediators. Cytokines such as $IL-1{\beta}$, IL-6, IL-10 and $TNF-{\alpha}$ were measured by immunochemical assay. In vitro, the macrophages 264.7 were classified into four groups. One group was a normal group. The other group was a (-) control group stimulated with LPS. And the third group was a (+) control group pretreated for 1 hour with hydrocortisone. And the fourth group was a sample group pretreated for 1 hour with Mori Cortex. After pretreatment, macrophage were incubated with lipopolysaccharide(LPS) $100\;ng/m{\ell}$ for 12 hour and media collected and $IL-1{\beta}$, IL-6, IL-10 and $TNF-{\alpha}$ concentrations in supernatants were measured each by Enzyme linked immuno-soubent assay. Mori Cortex were used $50\;{\mu}g/m{\ell},\;100\;{\mu}g/m{\ell},\;250\;{\mu}g/m{\ell},\;500\;{\mu}g/m{\ell},\;and\;1,000\;{\mu}g/m{\ell}$. Hydrocortisones were used $10^{-8}M,\;10^{-7}M,\;10^{-6}M,\;10^{-5}M\;and\;10^{-4}M$. In vivo, the SD rats were classified into three groups. One group was a normal group injected with normal saline into the abdominal cavity. The other was a control group prescribed to compound 48/80 after normal saline injection. And the third was a sample group prescribed to compound 40/80 after Mori Cortex injection. Then, the release of histamine, IL-6 and $TNF-{\alpha}$ were measured. Results : In vitro, Man Cortex significantly increased the release of $IL-1{\beta}\;and\;TNF-{\alpha}$ by LPS-stimulated macrophage 264.7 cells. And it significantly decreased the release of IL-10. In IL-6, Mori Cortex of low concentration significantly decreased the release of IL-6, but that of high concentration acted in reverse. In vivo, Man Cortex didn't show significant inhibitory effects on the release of histamine and IL-6 in comparison with that of the control group. But it significantly increased the release of $TNF-{\alpha}$ in comparison with that of the control group.

Pulmonary edema is a disease involving the principal symptoms: dyspnea, bloody phlegm, asthma, cough, etc. According to oriental medical references, Jeomglyukdaejosapaetang (J.D.T) was efficacious for dropsy, cough, dysnea, etc, so it was thought to be used for remedy of pulmonary edema. Therefore experimental study was performed to investigate the effects of J.C.T on pulmonary edema of the rats induced by the herbicide, paraquat.Thus the survival rats, respiratory rats, lung weights and histopathological view of the lungs of rats were studied. The results are as follows. 1. The survival rates at 72hours of the rats injected with paraquat and treated with J.D.T increased in B group(J.D.T + Cortex Lycii Radicis + Cortex mori). The others were not different with the control. 2. The respiratory rates of the rats which survived 72hours later significantly decreased in B group(J.D.T + Cortex Lycii Radicis + Cortex mori). 3. The lung weights of the rats which survived for 72hours later significantly decreased in B group(J.B.T + Cortex Lycii Radicis + Cortex mori). 4. The histopathological views of the lungs of rats induced by paraquat were seen severe hemorrhage, edema and some broken alveoli in control group. But B group(J.D.T + Cortex Lycii Radicis + Cortex mori) were seen little hemorrhage and interstitial hyperplasia. According to the above results, J.D.T + Cortex Lycii Radicis + Cortex mort is effective on the remedy for pulmonary edema of rats induced by paraquat.
