Objectives This study was to investigate the antioxidative capacity, antiobesity effect and anti-diabetes effects of Mori Fructus and dried Mori Fructus in Raw 264.7 cells and 3T3-L1 cells. Methods 3 different types of Mori Fructus extracts (water 100%, ethanol 30%, ethanol 100%) were used in this study. And 3 different types of dried Mori Fructus extracts (water 100%, ethanol 30%, ethanol 100%) were used in this study. Total polyphenol compund, total favonoid compound, DPPH radical scavenging, ROS activity, NO, cell proliferation were measured in the experiment. Expressions of adipogenic transcription factors including $C/EBP-{\alpha}$, $C/EBP-{\beta}$, $PPAR-{\alpha}$, $PPAR-{\gamma}$, $AMPK-{\alpha}$ were analyzed by Real time PCR. Results Mori Fructus extracts measurements are higher than dried Mori Fructus extracts measurements at Total flavonoid compound and total flavonoid compound. Mori Fructus extracts measurements are lower than dried Mori Fructus extracts measurements at DPPH radical scavenging, ROS activity, NO. In RT-PCR analysis, there is a tendency that dried Mori Fructus extracts inhibit the expression of $C/EBP-{\alpha}$, $C/EBP-{\beta}$ genes. In RT-PCR analysis, there is a tendency that dried Mori Fructus extracts promote the expression of $PPAR-{\alpha}$, $PPAR-{\gamma}$, $AMPK-{\alpha}$ genes. Conclusions Mori Fructus is effective on inhibiting the oxidation and dried Mori Fructus is effective on inhibiting the obesity and diabetes.

Mulberry has been reported to contain wide range of polyphenols and have chemopreventive activity. However, little has been known regarding the effect of mulberry fruits on cell viability in human glioma cells. The present study was undertaken to examine the effect of mulberry fruit (Mar; Fructus) on cell viability and to determine its underlying mechanism in human glioma cells. Cell viability and cell death were estimated by MTT assay and trypanblue exclusion assay, respectively. Reactive oxygen species (ROS) generation was measured using the fluorescence probe DCFH-DA. The mitochondrial transmembrane potential was measured with $DiOC_6$(3). Bax expression and cytochrome c release were measured by Western blot analysis. Caspase activity was estimated using colorimetric kit. Mori Fructus resulted in apoptotic cell death in a dose- and time-dependent manner. Mori Fructus increased ROS generation and the Mori Fructus-induced cell death was also prevented by antioxidants, suggesting that ROS generation plays a critical role in Mari Fructus-induced cell death. Western blot analysis showed that Mori Fructus treatment caused an increase in Bax expression, which was inhibited by the antioxidant N-acetylcysteine (NAC). Mori Fructus induced depolarization of mitochondrial membrane potential and its effect was inhibited by the antioxidants NAC and catalase. Mori Fructus induced cytochrome c release, which was inhibited by NAC. Caspase activity was stimulated by Mori Fructus and caspase inhibitors prevented the Mori Fructus-induced cell death. These findings suggest that Mori Fructus results in human glioma cell death through ROS-dependent mitochondrial pathway in human glioma cells.

Etiological studies of diabetes and its complications showed that oxidative stress might play a major role, Therefore, many efforts have been tried to regulate free oxygen radicals for treating diabetes and its complications. Mori Fructus extract has been known to be effective for the antidiabetic, antihyperlipidemic and antiobesitic prescription, and composed of four crude herbs, The aim of this study was to investigate the effect of Mori Fructus extract in male ob/ob mouse with severe obesity, hyperinsulinemia, hyperglycemia, hyperlipidemia. Mice were grouped and treated for 5 weeks as follows. Both the lean (C57BL/6J black mice) and diabetic (ob/ob mice) control groups received standard chow. The experimental groups were fed with a diet of chow supplemented with 7.5, 15 and 30 mg Mori Fructus extract per 1 kg of body weight for 14 days. The effects of Mori Fructus extract on the ob/ob mice were observed by measuring the serum levels of glucose, insulin, lipid components, and the kidney levels of reactive oxygen species (ROS), MDA+HAE, GSH and also the enzyme activities involved in polyol pathway. Western blotting was performed using anti-AGE, anti-RAGE respectively. Mori Fructus extract lowered the levels of serum glucose and insulin in a dose dependent manner. Total cholesterol, triglyceride and free fatty acid levels were decreased, while the HDL-cholesterol level was increased, in Mori Fructus extract treated groups. Renal aldose reductase and sorbitol dehydrogenase activities were increased in the ob/ob mice, whereas those were inhibited in the Mori Fructus extract-administered groups. Mori Fructus extract inhibited the generation of ROS in the kidney. MDA+HAE level was increased and the GSH level was decreased in the ob/ob mice, whereas those were improved in the Mori Fructus extract-administered groups. Mori Fructus extract inhibited the expression of AGE, RAGE in the ob/ob mice. The results suggested that Mori Fructus exerted the antidiabetic and antihyperlipidemic activities by regulating the activities of polyol pathway enzymes, scavenging the ROS, decreasing the MDA+HAE level, increasing the GSH level and inhibiting the expression of AGE, RAGE in the ob/ob mice.

Objectives : Peroxynitrite $(ONOO^-)$, superoxide anion radical $({\cdot}O_2^-)$ and nitric oxide (NO) are cytotoxic because they can oxidize several cellular components such as proteins, lipids and DNA. They have been implicated in the aging processes, and age-related diseases such as Alzheimer's disease, rheumatoid arthritis, cancer and atherosclerosis. The aim of this study was to investigate the $ONOO^-$, NO, and $({\cdot}O_2^-)$ scavenging and anti-inflammatory activities of Mori Fructus in ob/ob mice. Methods : Mice were grouped and treated for 5 weeks as follows. Both the normal lean (C57/BL6J black mice) and control obese (ob/ob mice) groups received the standard chow. The experimental groups were fed a diet of chow supplemented with 7.5, 15 and 30 mg Mori Fructus per 1 kg of body weight for 14 days. For this study, the fluorescent probes, namely 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) and dihydrorhodamine 123 (DHR 123) were used. Western blotting was performed using anti-phospho $I{\kappa}B-\alpha$, anti-IKK-$\alpha$, anti-NF-${\kappa}B$ (p50, p65), anti-COX-2 and anti-iNOS respectively. Results : Mori Fructus inhibited the generation of $ONOO^-$, NO and $({\cdot}O_2^-)$ in the lipopolysaccharide (LPS)-treated mouse kidney postmitochondria in vitro. The generation of $ONOO^-$, NO and $({\cdot}O2^-)$ were inhibited in the Mori Fructus-administered ob/ob mice groups. The GSH/GSSG ratio decreased in the ob/ob mice, whereas they improved in the Mori Fructus-administered groups. Mori Fructus inhibited the expression of phospho $I{\kappa}B-\alpha$, IKK-$\alpha$, COX-2, iNOS genes, and thereby the activation of NF-$I{\kappa}B$. Conclusions : These results suggest that Mori Fructus is an effective $ONOO^-$, $({\cdot}O_2^-)$ and NO scavenger, and therefore it might be a potential therapeutic drug against the inflammation process and inflammation-related diseases.

Acute toxicity on the water extract of Mori Fructus was examined in male and female mice. The water extract of Mori Fructus was orally administered at a dose of 5 mg/kg, 50 mg/kg, 300 mg/kg and 2,000 mg/kg and had been observed for two weeks. No mortality and abnormal clinical signs were shown for the observation period. At the terminal sacrifice, there were no difference in net body weight gain, organ weight and gross pathological findings among the groups treated with different doses of the water extract of Mori Fructus. The results suggested that under the condition employed in this study $LD_{50}$ would be more than 2,000 mg/kg. All the data obtained the experiments lead to the water extract of Mori Fructus should have very low acute toxicity.

The antihistaminic action of eighteen herbal medicines was investigated by the radioligand binding and functional assays. The hexane fractions of Trichosanthis radix, Mori cortex radicis and Evodiae fructus dose-dependently inhibited [$^3$H]mepyramine binding to H$_1$ receptor and histamine-induced contraction in guinea-pig brain homogenates and isolated guinea-pig ilea, respectively. Antihistaminic action of the hexane and ethylacetate fractions of Mori cortex radicis and the hexane fraction of Evodiae fructus was more potent than their antimuscarinic action evaluated from the inhibition of [$^3$H]QNB binding and carbachol response. The ethylacetate and chloroform fractions and six known flavonoids from Scutellariae radix also inhibited histamine-induced contraction, but antihistaminic potencies of these fractions and compounds were almost identical with their antimuscarinic potencies. The hexane fractions of Mori cortex radicis and Evodiae fructus, as shown in ketotifen, inhibited selectively the increase of cutaneous vascular permeability induced by histamine. However, wogonin (SC-1) from Scutellariae radix was a nonselective inhibitor for the effect of histamine and serotonin on the vascular permeability. These results demonstrate that the hexane and ethylacetate fractions of Mori cortex radicis and the hexane fraction of Evodiae fructus have the selective histamine H$_1$ receptor blocking activities.
