Objectives : We investigated differances of physiological functionalities in the steamed Schisandrae Fructus. Methods : The samples were extracts of dryed schisandrae fructus without steaming process (S0), extracts of schisandrae fructus with three times steamed (S3), extracts of schisandrae fructus with five times steamed (S5) and extracts of schisandrae fructus with seven times steamed (S7). We analyzed contents of schisandrin, gomisin, total polyphenol and flavonoid and antioxidant activities. We researched antiinflammation effects for Raw264.7 cells. To evaluate liver protective activity, we measured AST, ALT and gamma-GTP in serum of alcoholic mice. Results : As the steaming number of schisandrae fructus increase, the contents of schisandrin and gomisin were more increased. The contents of total polyphenol of S5 and S7 were significantly increased compared to that of S0. DPPH free radical scavenging activities of S5 and S7 were significantly increased compared to that of S0, ABST radical scavenging activities of S3 and S5 were significantly increased compared to that of S0 in vitro. The NO production of all sample was significantly decreased compared to control, PGE2 release of S3, S5 and S7 were significantly decreased compared to control. IL-$1{\beta}$ release of S5 and S7 were significantly decreased. AST, ALT and gamma-GTP of S3, S5 and S7 were significantly decreased compared to control. Conclusions : We think that extracts of schisandrae fructus with steaming process may have more potential efficacy than a schisandrae fructus without steaming process.

In order to observe the change of ginsenosides, two simplified decoctive conditions are set up aqueous citric acids (0, 12.5, 25, 50, 75, and 100 mM) with ginseng powder (3 g) and Schisandrae Fructus (0, 1, 2, 3 g) with ginseng powder (3 g). Decoctive temperature and duration are $95^{\circ}C$ and 1.5 h. The contents of major ginsenosides are decreased by increasing concentration of citric acid. But the contents of converted ginsenosides have not been a noticeable increase. In the decoctive condition with Schisandrae Fructus, the contents of major protopanaxdiol ginsenosides seriously decreases that compared with major protopanaxtriol ginsenosides. Therefore, Schisandrae Fructus provides the condition that predominantly converts protopanaxdiol ginsenosides in ginseng decoction.

Dried fruits of Schizandra chinensis Baillon, Fructus Schisandrae, have been widely used for many years to prevent and treat various diseases in Asian countries including Korea and Russia. It has recently been reported that extracts of Fructus Schisandrae are effective for controlling muscle and skeletal diseases. In this study, we investigated the efficacy of ethanol extract of Fructus Schisandrae (EEFS) on apoptosis and inflammatory response in gastrocnemius muscle of dexamethasone-induced catabolic muscle atrophy mice as part of natural substance discovery and functional analysis for improving muscle function. According to the results of this study, EEFS supplementation attenuated body weight gains and suppressed calf thickness loss in dexamethasone-induced muscle atrophic mice. Gastrocnemius muscle immunohistochemistry showed that expression of caspase-3 and poly(ADP-ribose) polymerase, which are representative apoptotic markers, was markedly increased in dexamethasone control mice; however, their expression was effectively reduced in the EEFS-fed mice. EEFS supplementation also prevented dexamethasone-induced increases in immunoreactivity of muscle fibers for myostatin, an important negative regulator of skeletal muscle mass. In addition, EEFS significantly normalized the increased numbers of nitrotyrosine, 4-hydroxynonenal and inducible nitric oxide synthase-positive muscle fibers compared to that found in dexamethasone control mice. These results suggest that EEFS protects dexamethasone-induced muscular atrophy by decreasing apoptosis and inflammatory responses, and EEFS is more likely to be developed as a muscle strengthening agent.

Objective : This study was intended to ascertain the protective effect of phenolic-rich fraction (PRF) from Fructus Schisandrae on SH-SY5Y cells. Methods : PRF was obtained from the 80% ethanol extract of Fructus Schisandrae by Sepabeads SP-850 column chromatography. The neuroprotective effect of the FS PRS was investigated due to the hydrogen peroxide $(H_2O_2)-induced$ apoptosis of cultured SH-SY5Y cells. Results : Cell viability assays revealed that pretreating SH-SY5Y cells with PRF (10-200 ${\mu}g/mL$) resulted in significant dose-dependent protection against $H_2O_2-induced$ cell death. The effect was assessed by flow cytometric analysis of DNA contents using propidium iodide (PI) staining. The population of apoptotic cells was increased by 32.89% in only $H_2O_2$ (150 ${\mu}M$)-treated environment, but it was reduced by pre-treatment of FS PRF (200 ${\mu}g/mL$) to 21.61%. $H_2O_2-induced$ caspase-3 activation and PARP cleavage were reduced in FS PRF pre-treated cells, and PRF led to an apparent suppressive effect on the oxidative stress induced by reactive oxygen species (ROS). Conculsion : This study showed that Fructus Schisandrae should be useful for the treatment prevention of neurodegenerative diseases associated with elevated ROS levels.

The fruits of Schisandra chinensis have been used as an edible ingredient and traditional medicine in Korea. Due to morphological similarities of dried mature fruits, the correct identification of S. chinensis from other closely related Schisandrae species is very difficult. Therefore, molecular biological tools based on genetic analysis are required to identify authentic Schisandrae Fructus. Random amplifed polymorphic DNA (RAPD) and Sequence Characterized Amplified Region (SCAR) were used to develop an easy, reliable and reproducible method for the authentication of these four species. In this paper, we developed several RAPD-derived species specific SCAR markers and established a multiplex-PCR condition suitable to discriminate each species. These genetic markers will be useful to distinguish and authenticate Schisandrae Fructus and four medicinal plants, S. chinensis, S. sphenanthera, S. repanda and K. japonica, in species level.

Objectives: This study used the basic principle of Oriental medicine, the sovereign, minister, assistant and courier principle (君臣佐使論) to investigate the effects of the component of ONGABO, which is composed of Ginseng Radix (Red Ginseng), Angelica Gigantis Radix, Schisandrae Fructus, Cuscuta Semen and Curcumae tuber on the viability of HepG2 cells. Methods: Single and mixed extracts of the component of ONGABO were prepared by lypohilizing powder of Red Ginseng (6-year root from Kanghwa), Angelica Gigantis Radix, Schisandrae Fructus, Cuscuta Semen, Curcumae Tuber (from Omniherb Co., Ltd., Korea) at the laboratory of herbal medicine in Woosuk University and were eluted after being macerated with 100% ethanol for three days. The cell viability of HepG2 was determined by using an absorptiometric analysis with PrestoBlue (Invitrogen) reagent after the plate had been incubated for 48 hours. All of the experiments were repeated three times to obtain the average value and standard deviation. The statistical analysis was done and the correlation factor was obtained by using Microsoft Office Excel 2007 and Origin 6.0 software. Results: Although Ginseng Radix (Red Ginseng) and Schisandrae Fructus did not enhance the viability of HepG2 cells, they were shown to provide protection of those cells. On the other hand, Angelica Gigantis Radix decreased the viability of HepG2 cells significantly, Cuscuta Semen and Curcumae Tuber had a small or no effect on the viability of HepG2 cells. Conclusions: In the sovereign, minister, assistant and courier principle (君臣佐使論), Ginseng Radix (Red Ginseng) corresponds to the sovereign component because it provides cell protection effects, Angelica Gigantis Radix corresponds to minister medicinal because it kills cells, Schisandrae Fructus corresponds to the assistant medicinal to help red ginseng having cell protect effects. Cuscuta Semen and Curcumae Tuber correspond to the courier medicinal having no effect in cell viability in HepG2. We hope this study provides motivation for advanced research on the sovereign, minister, assistant and courier principle.

Objectives : The purpose of this study was to investigate the effect of FS for the modulation of ROS and MMP in a hypoxic model of cultured rat cortical cells. Methods : For the effect of FS on the viability, FS was added to culture media (neurobasal supplemented with B27) and cell viability was measured by LDH assay. To investigate the effects of FS on ROS generation and MMP preservation, cells grown in FS-containing media were given a hypoxic shock(2% $O_2/5%$ $CO_2$, $37^{\circ}C$, 3 hrs) on DIV 10, stained with $H_2DCF-DA$(10 nM) and JC-1, respectively, and observed by fluorescent microscope. Results : 1. FS has a protective effect of cortical cells in both normoxia and hypoxia. 2. FS reduced the generation of ROS and this reduction was especially significant at 3 days after hypoxia. 3. FS was effective for the maintenance of MMP in hypoxia, and this efficacy was especially significant at 3 days after hypoxia. Conclusions : Taken together, these results indicate that FS attenuates ROS generation and MMP dissipation, which eventually protects from neuronal cell death in hypoxia.

It has been suggested that oxidative stress of reactive oxygen species(ROS) may play a key role in the pathogenesis of neuronal complications. The aim of this study was to examine the cytotoxic effect of hydrogen peroxide(H₂O₂) in the cultured mouse cerebral neurons and the protective effect of Schisandrae Fructus(SF) on ROS-induced neurotoxicity. Cytotoxic effect of H₂O₂ and neuroprotective effect of SF were determined by MTT assay. H₂O₂ decreased cell viability in dose-and time-dependent mannner, and SF decreased H₂O₂-induced neurotoxicity in these cultures. From above the results, H₂O₂ has toxic effect, and herb extract, SF is very effective against H₂O₂-induced neurotoxicity in cultured cerebral neurons of mouse.

Objectives: The present study aimed at investigating the effects of Schisandrae Fructus (SF) on menopause symptoms in ovariectomized mice. Methods: 6 weeks old female mice were ovariectomized (OVX), and the OVX mice were fed with a three doses of SF (25, 100, and 400 mg/kg, respectively) or $17{\beta}$-estradiol (E2, 0.5 mg/kg) 3 times a week for 6 weeks. Body weight was measured at every week and uterus weight was also measured at the end of experiment. Lipids and osteocalcin levels in serum were analyzed. Results: The uterine weight was not changed in SF treated group, while E2 intake increased the reduced uterine weight by OVX. Although Body weight was increased since two weeks after ovariectomy compared with sham operated group, there was no change in SF or E2 treated group compared with OVX. But LDL was significantly reduced in SF (400 mg/kg) or E2 fed mice and SF or E2 treatment decreased enhanced osteocalcin level by OVX. Conclusion: These results indicated that SF would be effective in the improvement of LDL level and osteoporosis on menopause.
