Abstract
Cornus officinalis is widely distributed in Korea, and its fruit has been used to make as herbal drug for traditional medicine in Korea, Japan, and China because of its tonic, analgesic, and diuretic properties. However, the effects of C. officinalis methanol extract (COME) on melanogenesis remain poorly understood. We evaluated the melanogenic capability of COME in melan-a cells, which are immortalized mouse melanocytes. COME increased melanin synthesis in a dose-dependent manner. Treatment with 12.5 μg/mL of COME significantly increased melanin content by 36.1% (p < 0.001) to a level even higher than that (31.6%) of 3-isobutyl-1-methyl-xanthine, a well-known pigmentation agent. COME also upregulated tyrosinase activity and its messenger RNA and protein expression. In addition, COME upregulated the expression of tyrosinase-related proteins 1 and 2 and microphthalmia-associated transcription factor-M messenger RNA expression. These results imply that COME may be appropriate for development as a natural product to treat hair graying.

Abstract
1. Corni fructus is the fruit of Cornus officinalis, a dogwood species. This study was conducted to prepare fermented corni fructus preparation (FCFP) and fermented kelp (FK) from corni fructus and by-products of Laminaria japonica fermented with Bacillus subtilis and Aspergillus oryzae. 2. The effects of dietary FCFP and FK as replacer of oxytetracycline (OTC) on growth performance, meat composition, meat oxidative stability, and emissions of ammonia (NH3) and hydrogen sulphide (H2S) from broiler chicken droppings were investigated. 3. A total of 140 d-old broiler chicks were randomly allotted to 4 dietary treatments including control, OTC (0.05 g/kg), FCFP (5 g/kg), and FK (5 g/kg). 4. Overall, inclusion of FCFP resulted in lower weight gain and feed intake during the overall experimental period. Broilers fed FCFP diets tended to have lower crude fat and higher crude ash content in the carcasses. 5. In the fresh state, the malondialdehyde (MDA) value of broiler meat was lower in the FK supplemented group. At one week, meat from broilers fed antibiotic and FK diets had lower MDA values, whereas at 2 weeks broiler meat from all dietary treatment groups had lower MDA values than the control. 6. Dietary supplementation with FK significantly reduced faecal NH3 emissions throughout the experimental period, whereas dietary OTC and FCFP supplementation increased NH3 emissions at 2 and 4 weeks. There were no significant effects of dietary treatments on H2S emissions throughout the experimental period, except during week one, when FCFP supplementation reduced the emission. 7. In conclusion, dietary supplementation with 5 g/kg FK improved the oxidative stability of broiler meat and reduce faecal NH3 emissions without affecting growth performance.

Abstract
Objective: This study investigated the safety and therapeutic efficacy of Di Huang Yin Zi (DHYZ), a traditional Chinese decoction used to treat neurological disorders, in spinal cord injury (SCI). Methods: In this doubleblind, placebo-controlled study, patients with traumatic SCI and American Spinal Injury Association (ASIA) impairment grades B - D were randomized to receive DHYZ ( n = 30) or placebo ( n = 30) for 12 weeks. Both groups also received rehabilitation therapy during the study period. Motor and sensory function and activities of daily living (ADL) were assessed before treatment and at 4-week intervals. Results: Significantly more patients in the DHYZ group showed an improved ASIA impairment grade during the treatment period (32.1%) compared with the placebo group (10.3%), and scores for sensory and motor function and ADL at the end of the treatment period were significantly higher in the DHYZ group than in the placebo group. No serious side-effects were reported. Conclusions: DHYZ was found to improve neurological function in patients with SCI and may be an effective adjuvant therapy to enhance functional recovery.

Abstract
PURPOSE Diabetes is the leading cause of end-stage renal failure. The present study was undertaken to characterize the effects of Corni Fructus on diabetic nephropathy in streptozotocin-induced diabetic rats and their mechanisms. MATERIALS AND METHODS Streptozotocin-diabetic rats were orally administrated with Corni Fructus at a dose of 100, 200 or 400 mg/kg body mass for 40 days. RESULTS Corni Fructus-treated diabetic rats showed significant decreases of blood glucose, urinary protein levels and water consumption. Corni Fructus also reduced serum total cholesterol, total triglyceride and low-density lipoprotein cholesterol levels, and showed a tendency of enhancing high-density lipoprotein cholesterol level. Levels of serum albumin and creatinine in diabetic rats were also significantly reduced by Corni Fructus administration at a dose of 200 and 400 mg/kg body mass compared with non-treated diabetic rats. Corni Fructus increased catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidose (GSH-px) activities in the kidneys of diabetic rats. Furthermore, Corni Fructus treatment enhanced renal peroxisome proliferator-activated receptor-γ (PPARγ) expression in diabetic rats. CONCLUSION These results demonstrated that Corni Fructus may have the potential to protect the animals from diabetic nephropathy by amelioration of oxidative stress and stimulation of PPARγ expression.

Abstract
Chlorogenic acid (CGA) widely exists in edible and medicinal plants. We aimed to evaluate the effect of CGA on the protection from apoptosis by methylmercury (MeHg) in PC12 cells. Cell viability was evaluated by MTT assay. Apoptosis was assayed by flow cytometry detection. Caspase-3 activity was measured by confocal microscopy. Intracellular GSH levels were determined by bicinchoninic acid protein assay. Intracellular reactive oxygen species (ROS) was assessed by means of chloromethyl-dihydrodichlorofluorescein diacetate. Glutathione peroxidase (GPx) activity was determined by UV. In order to elucidate the action of CGA, the protective effects of CGA were compared to Vit.E. CGA was effective at protecting PC12 cells against MeHg-induced damage in dose-dependent manner. CGA not only suppressed the generation of ROS, the decrease of activity in GPx and the decrease of GSH, but also attenuated caspase-3 activation in PC12 cells by MeHg. CGA eventually protected PC12 cells against MeHg-induced apoptosis. The results highlighted that CGA may exert neuroprotective effects through its antioxidant actions.

Abstract
Buckwheat (Fagopyrum esculentum Moench) hull was extracted with 70% ethanol and then further fractionated with n-hexane, chloroform, ethyl acetate, and water stepwise. In the in vitro test (SRB assay), hexane and ethyl acetate fractions showed higher inhibition effects against MCF-7 cells than other samples at the 1 mg/mL level: 89% and 93.2%, respectively. They also displayed higher inhibition rates against Hep3B cells of 83.6% and 75.3%, respectively, at 1 mg/mL. The ethyl acetate fraction yielded the highest inhibition rate against A549 cells with the level of 0.25 mg/mL, but it showed a lower inhibition rate than the hexane and chloroform fractions at higher levels of sample, i.e., 0.75 and 1.0 mg/mL. All samples showed higher inhibition effects against AGS human gastric carcinoma than any other cancer cells. The inhibition rates against HeLa cells were 81.2% and 82.0% for the chloroform and butanol fraction with 0.5 mg/mL, respectively. However, all samples yielded an inhibition rate of less than 35% against normal cells, at all treatment levels, except the ethanol extract. All extracts at doses of 25 and 50 mg/kg showed decreases of more than 20% and 42%, respectively, in tumor formation in sarcoma-180 implanted mice except for the aqueous fraction. From these results, it is suggested that buckwheat hull possesses anticancer properties against a variety of different cancer cell lines.

Abstract
Corni fructus has been used as a tonic, analgesic, and diuretic in Korean herbal medicine. The present investigation was undertaken to evaluate the antioxidative effect of corni fructus and its capacity to protect cells against oxidative damage. The radical scavenging activity of corni fructus extracts was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH), and the antioxidant activity was determined by measuring the peroxide value in a linoleic acid emulsion system. In addition, human umbilical vein endothelial cells (HUVECs) were treated with corni fructus extracts and incubated with H(2)O(2) to investigate protection against apoptosis induction. Both ethanol and water extracts of corni fructus produced higher DPPH radical scavenging activity than hexane, chloroform, and ethyl acetate extracts. Strong antioxidative activities of both water and ethanol extracts were observed in an emulsion system containing linoleic acid and phosphate buffer. The incubation of HUVECs with the addition of ethanol extract significantly decreased H(2)O(2)-initiated damage of endothelial cells, but the water extract did not. The pretreatment with ethanol extract, but not with water extract, significantly decreased apoptotic damage of the H(2)O(2)-treated HUVECs and kept the morphological normality. This study demonstrates that corni fructus is a potent antioxidant substance, and suggests that further investigation is needed to characterize the difference between extract types and to identify its antioxidant compounds.

Abstract
OBJECTIVE To develop a method to cope with stress-induced reduction in immunocompetence, we evaluated the immunomodulatory activities of a biological response modifier derived from the mycelia of the basidiomycete Tricholoma matsutake (CM6271) in mice under repeated restraint stress. METHODS C57BL/6 mice were inserted, one per tube, into 50-ml polypropylene tubes into which more than 30 ventilation holes had been drilled, and were restrained everyday for 20 days in this fashion for set periods of time. Natural killer (NK) cell activity and NK1.1-positive cell counts in the spleen, ACTH and corticosterone levels in the blood were determined. CM6271 was orally administered daily during the restraint stress period. RESULTS (1) When the mice were restrained in a confined space for 6 h per day for 20 days, the NK cell activity and the NK1.1-positive cell counts in the spleen significantly decreased after day 5 with an increase in the blood ACTH and corticosterone levels. (2) Oral administration of CM6271 during the restraint stress period significantly prevented the stress-induced decrease in NK cell activity. The effect was dependent on the timing, duration, and doses administered. (3) CM6271 did not significantly affect the splenic NK1.1-positive cell counts or the levels of blood ACTH and corticosterone in restraint-stressed mice. CONCLUSION The above findings suggest that CM6271 inhibits the restraint stress-induced decrease of NK cell activity in a timing of administration and dose-dependent manner.

Abstract
Neuronal apoptosis is one of the pathological features of Alzheimer's disease (AD). Morphological pathology reveals that neuronal apoptosis is associated with senile plaques containing amyloid-beta peptide (Abeta) in AD brains. Reactive oxygen species (ROS) has been proposed to be involved in the apoptotic mechanism of Abeta-mediated neurotoxicity. In the present study, using a rat pheochromocytoma (PC12) cell line, we investigated the effect of Pycnogenol (PYC), a potent antioxidant and ROS scavenger, on Abeta(25-35)-induced apoptosis and ROS generation. We used vitamin E, a known antioxidant agent, to verify the effect of PYC. Abeta(25-35)-induced apoptosis in PC12 cells was demonstrated by: (1) a dose-dependent loss of cell viability; (2) a time- and dose-dependent increase in the apoptotic cells; (3) an induction of DNA fragmentation; and (4) an increase in caspase-3 activity and cleavage of poly (ADP-ribose) polymerase (PARP). Our data showed that a significant increase in ROS formation preceded apoptotic events after PC12 cells were exposed to Abeta(25-35). We further found that PYC not only suppressed the generation of ROS but also attenuated caspase-3 activation, DNA fragmentation, PARP cleavage, and eventually protected against Abeta-induced apoptosis. Vitamin E also suppressed cell death and caspase-3 activation induced by Abeta(25-35). Taken together, these results suggest that ROS may be involved in Abeta-induced apoptosis in PC12 cells. They further suggest that PYC can reduce apoptosis, possibly by decreasing free radical generation in PC12 cells.
