  • We tested to determine if Mori Cortex Radicis extract has antioxidant activities and its potential mechanism of action was explored. Anti-oxidative effects were tested by measuring free radical and nitric Oxide (NO) scavenging activity, and reducing power. Since iNOS and COX-2 are important enzymes responsible for the production of free radicals in the cell, Mori Cortex Radicis extract was tested as to whether it could inhibit iNOS and COX-2 expression in LPS stimulated Raw cells. 70% methanolic extract of Mori Cortex Radicis exerted significant DPPH free radical and NO scavenging activities. In addition, the Mori Cortex Radicis extract exerted dramatic reducing power with maximal activity observed at 1 mg/ml (11-fold over control). Production of iNOS induced by LPS was significantly inhibited by the Mori Cortex Radicis extract, suggesting it could inhibit NO production by suppressing iNOS expression. COX-2 induced by LPS was also significantly inhibited by the Mori Cortex Radicis extract. The extract contains well known antioxidant components including phenolics, flavonoids and anthocyanin at the concentration of 0.23 mg/g, 42.97 mg/g and 12.08 mg/g, respectively. These results suggest that 70% methanolic extract of Mori Cortex Radicis exerts significant anti-oxidant activity via inhibiting iNOS and COX-2 induction.

  • The purpose of this study was to investigate the antioxidant effects of Mori cortex radicis powder and to determine the optimal composite recipe by testing different amount of Mori cortex radicis powder and sugar in cookies prepared with Mori cortex radicis powder. In regard to its antioxident effects, Mori cortex radicis powder had a total phenolic content and DPPH free radical scavenging activity of 149.56 mg GAE/g and $137.77{\mu}g/mL$, respectively. The response surface methodology was used to obtain ten experimental points (including two replicates for Mori cortex radicis powder and sugar) and Mori cortex radicis cookie formulation was optimized using rheology. The results of the sensory evaluation produced significant values for color (p<0.05), texture (p<0.05), sweetness (p<0.01) and overall quality (p<0.05), and the results of instrumental analysis showed significant values in sweetness (p<0.001), redness (p<0.01) and spread ratio (p<0.5). As a result, the optimum formulations obtained by numerical and graphical methods were found to be 16.84 g of Mori cortex radicis powder and 64.42 g of sugar.

  • Mori Cortex Radicis is distributed in Northwestern China, northern Asia, northern Europe, North America, and Korea. This extracts drops sugar in bloods and inhibits cyclic AMP phophodiesterase. In this study, we investigated whether Mori Cortex Radicis would cause apoptotic death of A549 lung cancer cells. To examine the apoptotic effect of Mori Cortex Radicis, cytotoxicity assay, DNA fragmentation analysis, caspase-3 activity assay, and Western blotting for caspase-3, caspase-9 and poly(ADP-ribose) polymerase (PARP) and cytochrome c were performed. Treatment of cells with Mori Cortex Radicis was shown to induce cell death in a dose-dependent manner. DNA fragmentation was made in response to Mori Cortex Radicis. The active fragments of caspase-3, caspase-9 and PARP were almost completely induced and cytochrome c was released following exposure to Mori Cortex Radicis. To elucidate the apoptotic mechanisms, RT-PCR and Western blot analyses for the expression of Bcl-2, Bu and Cox-2 were carried out. Treatment with Mori Cortex Radicis was expressed the reduction of Bcl-2 and Cox-2 and the induction of Bax. Especially p21 and p53 were increased prior to untreated control, while cyclin E and cyclin D1 decreased in the cytosol. These results suggest that the effect Mori Cortex Radicis is associated with the cell cycle arrest and pro-apoptotic cell death in A549 lung cancer cells.

  • In order to evaluate the protective effects of extracts of Mori cortex radicis on carbon tetrachloride-induced hepatotoxicity, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactic dehydrogenase, malondiadehyde values and glutathione S-transferase activity were measured in ICR mice. The activities of serum aminotransferase and the hepatic content of lipid peroxide after carbon tetrachloride-treatment were markedly increased than normal control but those levels were significantly decreased by the treatment of butanol fraction of Mori cortex radicis mathanol extract. Glutathione S-transferase activity was decreased by carbon tetrachloride than control, but that also inhibited by the treatment of butanol fraction of Mori cortex radicis methanol extract. These results demonstrate a possible hepatoprotective role of extract role of extract of Mori cortex radicis against ${CCl_4}-induced$ hepatoxicity in vivo.

  • 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.

  • 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.

  • 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.
