BACKGROUND/OBJECTIVE: Orostachys japonicus A. Berger (Crassulaceae) has been used in traditional herbal medicines in Korea and other Asian countries to treat various diseases, including liver disorders. In the present study, the anti-fibrotic effects of O. japonicus extract (OJE) in cellular and experimental hepatofibrotic rat models were investigated. MATERIALS/METHODS: An in vitro hepatic stellate cells (HSCs) system was used to estimate cell viability, cell cycle and apoptosis by MTT assay, flow cytometry, and Annexin V-FITC/PI staining techniques, respectively. In addition, thioacetamide (TAA)-induced liver fibrosis was established in Sprague Dawley rats. Briefly, animals were divided into five groups (n = 8): Control, TAA, OJE 10 (TAA with OJE 10 mg/kg), OJE 100 (TAA with OJE 100 mg/kg) and silymarin (TAA with Silymarin 50 mg/kg). Fibrosis was induced by treatment with TAA (200 mg/kg, i.p.) twice per week for 13 weeks, while OJE and silymarin were administered orally two times per week from week 7 to 13. The fibrotic related gene expression serum biomarkers glutathione and hydroxyproline were estimated by RT-PCR and spectrophotometry, respectively, using commercial kits. RESULTS: OJE (0.5 and 0.1 mg/ mL) and silymarin (0.05 mg/mL) treatment significantly (P < 0.01 and P < 0.001) induced apoptosis (16.95% and 27.48% for OJE and 25.87% for silymarin, respectively) in HSC-T6 cells when compared with the control group (9.09%). Further, rat primary HSCs showed changes in morphology in response to OJE 0.1 mg/mL treatment. In in vivo studies, OJE (10 and 100 mg/kg) treatment significantly ameliorated TAA-induced alterations in levels of serum biomarkers, fibrotic related gene expression, glutathione, and hydroxyproline (P < 0.05-P < 0.001) and rescued the histopathological changes. CONCLUSIONS: OJE can be developed as a potential agent for the treatment of hepatofibrosis.

This study was conducted to improve the seed germination by low temperature and $GA_3$ in $Orostachys$ $japonicus$ A. Berger (Jirisan) and $O.$ $iwarenge$ (Mak.) Hara (Jejuyeonhwa), Korean native plants. Observation of the seeds using a stereo microscope showed that all seeds of the two species have wrinkled surface and oblong shape. Seed size ranged 0.77-1.00/0.25-0.37 mm (length/width), indicating that the seeds are minute seeds. When the seeds of two $Orostachsis$ species were sown into petri-dish and placed in a plant growth chamber of 10, 15, 20, or $25^{\circ}C$, 'Jirisan' showed seed germination below 20% at all temperatures and 'Jejuyeonhwa' 80% at only $10^{\circ}C$. Seed germination of 'Jirisan' increased up to 44% at $10^{\circ}C$ by low temperature ($4^{\circ}C$) storage for 10 days, but decreased again at storage for more than 20 days. The seeds of 'Jejuyeonhwa' showed a large increase in seed germination by low temperature for 20-30 days, which was 95% at $10^{\circ}C$, but low temperature for more than 40 days significantly decreased seed germination. Dipping treatment in GA3 solution of $50-400mg{\cdot}L^{-1}$ for different periods (3, 6, 12, and 24 hrs) remarkably improved germination rate and speed in both species, 80-100% in 'Jirisan' and 90-100% in 'Jejuyeonhwa' at all concentrations and dipping times used in this study.

Ultrastructural characteristics were examined with leaves of three species, O. japonicus A. Berger, O. malacophyllus Fisch., and O. sikokianus Owhi that probably have CAM mode. The mesophyll cells of these Orostachys possessed vacuoles with precipitates, myelin-like figures, and plasmalemmasomes, along with typical chloroplasts, microbodies and darkly stained bodies in their thin peripheral cytoplasm. Separation of the plasmalemma from the cell wall, leaving a space between them, was a common phenomenon in these species. A complex array of small to large vacuoles which contain small, membrane-bounded vesicles or vacuole-like structures were frequently found. A well-developed thylakoid system was observed in the chloroplasts and this indicates that the photosynthetic capacity of these mesophyll cells is probably active. A peculiar configuration of cytoplasm, especially around the chloroplasts, was also encountered. The variety of cytoplasmic constituents and vacuoles suggest the water-storing mesophyll cells may be complex in function. Some cellular features detected in this study strongly suggest the possible occurrence of CAM mode in Orostachys species.

The antioxidants activities in water and 95% ethanol extracts of wa-song (Orostachys japonicus A. Berger) dried by sun, hot air and lyophilization were measured in vitro reaction system. In reaction system containing linoleic acid, the antioxidant activities against lipid oxidation enhanced in proportion to storage time. The antioxidant activity of ethanol extracts was higher than that of water extracts. In the drying methods, wa-song extracts showed higher antioxidant activity in the other of hot air-dried, lyophilized and sun-dried. The lipid oxidation system containing the promoting factors, such as $Fe^{+2}$ and $Cu^{+2}$ions, also showed that the ethanol extract of hot air-dried wa-song possessed the highest antioxidant activity. Soybean oil and lard being added with various levels (0.1, 0.5 and 1.0 g/100 g) of the ethanol extract of hot air-dried wa-song were stored at $60^{\circ}C$ (for 28 days) or $180^{\circ}C$ (for 48 hr). Its extract appeared to lower the acid value of soybean oil, wheras it failed to lower the acid value for lard at early storage time, but it was lower than control and BHT after 28 days. Anicidine value and peroxide value were lower soybean and lard added wa-song extract than control and BHT for storage for 28 days at $60^{\circ}C$. In 28 days, its value was significantly decreased in proportion to sample concentration. TBA value was increased during storage time at $60^{\circ}C$, but it was significantly decreased by sample concentration after storage 36 hours at $180^{\circ}C$ storage. Therefore results suggest ethanol extract of hot air-dried wa-song could be potential candidates for natural antioxidants for materials containing lipid.

This study examined the biological activity and synergistic effects of an extract of Wa-song ($Orostachys$ $japonicus$, OE), a medicinal plant mixture (MPE) and a combination of both at different ratios (1:1, OMPE-1 and 3:1, OMPE-3). Extracts of the medicinal plants mixture were comprised of Baekbokyung, Changchul and Sa-in at the same ratio. The antioxidant activity of the extracts and their complex were tested $in$ $vitro$. The $in$ $vivo$ antioxidant activity was also analyzed by examining the lipid composition in the liver and kidney of streptozotocin (STZ)-induced diabetes rats. The nitric oxide radical scavenging activity was more than 50% in OMPE-3 at a 1,000 ${\mu}g$/mL concentration. Regarding metal ions, such as $Fe^{2+}$ and $Cu^{2+}$, the antioxidant activity of OMPE-1 and OMPE-3 was higher than that of OE and MPE. OMPE-1 and 3 had higher activity on $Cu^{2+}$ ions than $Fe^{2+}$ ions. The ${\alpha}$-glucosidase inhibition activity of the OE extract was higher than that of MPE and OMPE-1 but the relative activity of OMPE-3 was significantly higher than the others. Freeze-dried MPE, OMPE-1 and OMPE-3 were added to the diet at a level of 1% given to STZ induced diabetes rats for 4 weeks. The OMPE-1 and OMPE-3 administered groups showed significant decreases in the total lipid, total cholesterol and triglyceride levels in the liver and kidney. In these groups, the glycogen accumulation level of the liver was increased significantly. The content of thiobarbituric acid reactive substances (TBARS) in the liver and kidney was decreased but the DPPH radical scavenging activity was increased. These results suggest that Wa-song extract exhibits antioxidant and antidiabetic activity, which are enhanced by a complex with a medical plants extract.

This study was conducted to investigate the antioxidant activity of hot water extracts of wa-song (Orostachys japonicus A. Berger) dried using hot air (HWE) and frozen (FWE). Varying levels (0.1, 0.5 and 1.0 g/100 g) of HWE and FWE were added to soybean oil and lard. Chromaticity, anisidine value, acid value, peroxide value (POV) and thiobarbituric acid (TBA) value in oils were measured periodically during their storage for 28 days at $60^{\circ}C$. The chromaticity of edible oils showed a general increas with prolonged storage as well increasing levels of extracts. The anisidine value was not significantly increased during storage for 14 days, but was significantly increased after storage for 21 days in soybean oil and lard. The anisidine value of HWE on soybean oil was $12.60{\pm}0.92{\sim}13.82{\pm}0.68$ after storage for 28 days its value was lower than that of the control and buthylated hydroxy anisol (BHT). The antioxidant activity of HWE was found to be more effective than that of FWE. The acid value of HWE was significantly increased during storage from 14 to 21 days in soybean oil and from 7 to 14 days in lard. The antioxidant activity of FWE was particulary effective at the primary stage of the reaction system of lard storage. POV was highly increased during the storage periods between 7 and 14 days in soybean oil. The antioxidant activity in all the samples tested did not significantly increase after storage for 14 days, except when 0.1 g/ 100 g of FWE added to lard. TBA values of all the samples were lower than that of control and 0.02% BHT during their storage. The antioxidant activities of wa-song within the reaction system of oils were more effective in soybean oil than in lard.
