Bone maintains its homeostasis through balance between bone resorbing osteoclasts and bone forming osteoblasts. Thus, unusual balance between osteoclasts and osteoblasts leads to pathological bone diseases, such as osteoporosis, rheumatoid arthritis, autoimmune arthritis, periodontitis. Schisandra chinensis well known traditional herbal has been used for treatment of diseases in China, Korea, Japan, andothers. Recently, research studies have demonstrated that the lignans found in Schisandra chinensis stimulate osteoblasts and suggest that it may be helpful against osteoporosis. However, the inhibitory effect of water extract of Schisandra chinensis on osteoclast differentiation remains largely unknown. In this study, Water extract of Schisandra chinensis markedly suppressed RANKL-induced osteoclast differentiation in cultures of BMMs without cytotoxicity. The mRNA expression of c-Fos, NFATc1, and TRAP induced by RANKL was inhibited by water extract of Schisandra chinensis. It also suppressed c-Fos and NFATc1 protein expression. Taken together, these results suggest that water extract of Schisandra chinensis has the potential to serve as a treatment of bone disease such as osteoporosis.

Depression is one of the most common neuropsychiatric disorders and has been associated with the neuroendocrine system and alterations in behavior. Schisandra chinensis Baillon is one of major medicinal plants used as a Korea medicine and food sources, and has been processed in the fields of various food products and medicinal herbs. The chronic mild stress (CMS) protocol is widely used to evoke depressive-like behaviors in laboratory mice or rat. The CMS procedure induced some behavioral changes that are compatible with the common expectations, i.e. 'anhedonic' behavior and can affect corticosterone level. The present study, Schisandra chinensis extract administration by daily gavage from the 3 weeks exhibited an antidepressant-like effect on CMS-induced depression in mice. Schisandra chinensis extract administration at dose of 200mg/kg significantly increased the sucrose consumption, and decreased the immobility durations in forced swim test and tail suspension test. Furthermore the corticosterone level decreased than control group. In conclusion, Schisandra chinensis extract showed antidepressant-like effects on sucrose preference test, forced swimming test and tail suspension test based on CMS model.

This study was executed to evaluate the effects of natural herbal medicine extract on the antimicrobial activity and the artificial plaque formation. Schisandra chinensis, Sophora flavescens, Dryopteris crassirhizoma and Aristolochia contorta were extracted by 80% MeOH respectively and each concentration(5mg, 10mg, 20mg) of herbal medicine extract was tested to show the antimicrobial activity against S. mutans. To show the inhibition effect of herbal medicine extract on the artificial dental plaque formation each extract of 0.4% concentration was added into M 17 broth and inoculated with $5.0{\times}10^6$ of S. mutans. After 24 hour incubation each weight of artificial dental plaque was measured and compared with each other. Results obtained are as follows: 1. Dryopteris crassirhizoma showed very intense antimicrobial effect but Schisandra chinensis, Sophora flavescens and Aristolochia contorta showed a little difference against control. 2. Regarding artificial plaque formation inhibiting activity by each herbal extract at 0.4% concentration, Dryopteris crassirhizoma showed the perfect inhibition effect. Schisandra chinensis and Aristolochia contorta followed in order but Sophora flavescens showed the worst value. In conclusion, Dryopteris crassirhizoma showed strong antimicrobial effect against S. mutans and significant inhibiting effect on the artificial dental plaque formation.

Fruits of Schisandra chinensis (SC) Baill are considered a traditional herbal medicine for the treatment and alleviation of various diseases. The purpose of this study was to investigate the anti-cancer effects of SC extract in human breast adenocarcinoma cells (MCF-7). We used human breast adenocarcinoma cell line, MCF-7 cells. We examined cell death by MTT assay and caspase 3 and 9 assay with SC extract. To examine the inhibitory effects of SC extract, cell cycle (sub G1) analysis and mitochondrial membrane depolarization was done the MCF-7 cells after one day with SC extract. In addition, to investigate the transient receptor potential melastatin 7 (TRPM7) currents, we used the whole cell patch clamp techniques. Furthermore, TRPM7 channels were overexpressed in human embryonic kidney (HEK) 293 cells to identify the role of TRPM7 channels in MCF-7 cell growth and survival. SC extract inhibited the growth of MCF-7 cells in a dose-dependent fashion. Also we showed that SC extract induced apoptosis in MCF-7 cells by MTT assay, caspase 3 and 9 assay, sub-G1 analysis and mitochondrial membrane depolarization. SC extract inhibited the TRPM7 currents in MCF-7 cells and in TRPM7 overexpressed HEK 293 cells. Furthermore, TRPM7 channel overexpression in HEK 293 cells exacerbated SC extract-induced cell death. Our findings provide insight into unraveling the effects of SC extract in human breast adenocarcinoma cells and developing therapeutic agents against breast cancer.

Objectives : In this study, it was investigated the effects of solid-phase fermentation extraction with Phellinus linteus of discarded Schisandra chinensis extract (PS) and its action mechanism on dexamethasone-induced muscle atrophy in mice. Methods : In mice, muscle atrophy model was induced by dexamethasone (5 mg/kg, I.p) once daily for 2 weeks and with PS extract administration (100 and 300 mg/kg, p.o.) as treatment groups. The changes in body weights, grip strength, Treadmill test, muscle weights, and the expression of atrophy-related genes were measured in muscle atrophy mice. The histological changes of gastrocnemius tissues were also observed by H&E staining with measurement of myofiber size. Results : The administration of PS extract increased significantly body weights, grip strength, treadmill test and muscle weights in muscle atrophy mice. PS extract administration increased significantly the area of myofibers and inhibited structural damages of muscle and increased significantly the expression of myogenin and decreased significantly the expression of MuRF1, Atrogin1 and phosphorylation of AMPK and PGC1α in muscle tissues of muscle atrophy mice. Conclusions : These results indicate that PS extract has a improvement effects on muscle atrophy with stimulation of myogenic differentiation and inhibition of mRNA degradation that could be related with the activation of AMPK and PGC1α signaling pathways in muscle. This suggests that PS extract can apply to treat muscle atrophy in clinics.

BACKGROUND/OBJECTIVES: Male hypogonadism is a condition where the body does not produce enough testosterone and significantly impacts health. Age, obesity, genetics, and oxidative stress are some physiological factors that may contribute to testosterone deficiency. Previous studies have shown many pharmacological benefits of Schisandra chinensis (S. chinensis) Baillon as an anti-inflammatory and antioxidant. However, the molecular mechanism of attenuating hypogonadism is yet to be well established. This research was undertaken to study the effects of S. chinensis extract (SCE) on testosterone deficiency. MATERIALS/METHODS: S. chinensis fruit was pulverized and extracted using 60% aqueous ethanol. HPLC analysis was performed to analyze and quantify the lignans of the SCE. RESULTS: The 2,2-diphenyl-2-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) scavenging assays confirmed that the SCE and its major lignans (schisandrol A and gomisin N) inhibit oxidative stress. Effects of SCE analysis on the testosterone level under oxidative stress conditions revealed that both schisandrol A and gomisin N were able to recover the lowered testosterone levels. Through mRNA expression of TM3 Leydig cell, we observed that the SCE lignans were able to induce the enzymes involved in testosterone biosynthesis-related genes such as 3β-HSD4 (P < 0.01 for SCE, and P < 0.001 for schisandrol A and gomisin N), 17β-HSD3 (P < 0.001 for SCE, schisandrol A and gomisin N), and 17, 20-desmolase (P < 0.01 for schisandrol A, and P < 0.001 for SCE and gomisin N). CONCLUSIONS: These results support that SCE and its active components could be potential therapeutic agents for regulating and increasing testosterone production.
