Fructose-1, 6-diphosphate (FOP), a glycolytic metabolite is reported to ameliorate inflammation and inhibit the nitric oxide production in murine macrophages stimulated with endotoxin. It is also reported that FOP has cytoprotective effects against hypoxia or ischemia/reperfusion injury in brain and heart. In this study, we examined whether FDP has protective effects on UV-induced oxidative damage in skin cell culture system and human skin in vivo. FDP had a protective role in UVB-induced LDH release and ROS accumulation in HaCaT although it did not show direct radical scavenging effect in the experiment using 1, 1-diphenyl-2-picrylhydrazyl (DPPH). FDP also preserved cellular GSH content after UV irradiation in HaCaT and normal human fibroblast culture system. Cellular oxidative stress induces multiple downstream signaling pathways that regulate expression of multiple gene including MMP-1 and collagen, we examined the effects of FDP on UV-induced alteration of these protein expression in fibroblast culture and human skin in vivo. The increased MMP-1 expression in fibroblast and human skin by UV irradiation was significantly decreased by FDP. FDP also prevented the UV-induced decrease of collagen expression in fibroblast and human skin. Moreover, the decreasing the intracellular levels of reducing equivalents in human fibroblast by glutathione (GSH) depletion lowered the UVA dose threshold for reduction of procollagen expression, indicating that the differences of glutathione contents define the susceptibility of fibroblasts towards UV-induced reduction of procollagen expression. FDP also preserved cellular GSH content after UV irradiation, indicating that FDP has protective effects on UV-induced reduction of procollagen expression, which are possibly through maintaining intracellular reducing equivalent. Based on these premises, we examined the effect of daily use of a moisturizer containing FDP on facial wrinkle in comparison with vehicle moisturizer lacking FDP. In the clinical study, FDP significantly decreased facial wrinkle compared with vehicle alone after 6 months of use. Our results suggest that FDP has anti-aging effects in skin by increasing cellular antioxidant system and preventing oxidative signal and inflammatory reaction. Therefore FDP may be useful anti-aging agent for cosmetic purpose.

In the previous study, we reported the antioxidative activity and inhibition of melanogenesis of Ligularia stenocephala extracts. In this study, inhibitory effect on elastase and production type I procollagen were investigated. The compounds which was investigated were 4-hydroxyacetophenone, vanillin, chlorogenic acid, caffeic acid isolated from Ligularia stenocephala. They were slightly mild on elastase inhibition activity but 4-hydroxyacetophenone, vanillin exhibited good inhibition activity on collagen production. These results suggest that Ligularia stenocephala may have potential as an anti-aging ingredient in cosmetics.

Objectives: Based on data from Chinese and Indian traditional herbal medicines, gum resin of Ferula assa-foetida (sometimes referred to asafetida or asafoetida) has several therapeutic applications. The authors of various studies have claimed that asafetida has cytotoxic, antiulcer, anti-neoplasm, anti-cancer, and anti-oxidative effects. In present study, the anti-aging effect of asafetida on senescent human dermal fibroblasts was evaluated. Methods: Senescence was induced in in vitro cultured human dermal fibroblasts (HDFs) through exposure to $H_2O_2$, and the incidence of senescence was recognized by using cytochemical staining for the activity of ${\beta}$-galactosidase. Then, treatment with oleo gum resin of asafetida was started to evaluate its rejuvenating effect. The survival rate of fibroblasts was evaluated by using methyl tetrazolium bromide (MTT) assays. Real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blot assays were performed to evaluate the expressions of apoptotic and anti-apoptotic markers. Results: Our experiments show that asafetida in concentrations ranging from $5{\times}10^{-8}$ to $10^{-7}g/mL$ has revitalizing effects on senescent fibroblasts and significantly reduces the ${\beta}$-galactosidase activity in these cells (P < 0.05). Likewise, treatment at these concentrations increases the proliferation rate of normal fibroblasts (P < 0.05). However, at concentrations higher than $5{\times}10^{-7}g/mL$, asafetida is toxic for cells and induces cell death. Conclusion: The results of this study indicate that asafetida at low concentrations has a rejuvenating effect on senescent fibroblasts whereas at higher concentrations, it has the opposite effect of facilitating cellular apoptosis and death.

Objectives : Parkinson's disease (PD) is a neurodegenerative disease caused by dopaminergic neuronal death in the substantia nigra pars compacta. PD is known to be linked with mitochondrial dysfunction and increased oxidative stress. In this study, anti-cytotoxic and anti-oxidative effect of 12 herbal formulae were compared. Methods : According to experts' advice, 12 types of herbal formulae (Gamisoyosan, Galgeuntang, Galgeunhaegitang, Banhabaekchoolcheonmatang, Bojungikgitang, Boheotang, Sihogyejitang, Sihosogantang, Sihocheonggantang, Ojeoksan, Cheongsanggyeontongtang and Palmultang) were selected from 56 types of herbal formulae covered by the National Health Insurance Service in Korea. To detect anti-oxidative effect, 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay was performed, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed to detect anti-cytotoxic effect of 12 herbal formulae using SH-SY5Y human neuroblastoma cells. Results : In DPPH assay, anti-oxidant activity was increased in a dose-dependent manner and half maximal inhibitory concentration was highest in the order of Galgeuntang, Gamisoyosan, Galgeunhaegitang, Ojeoksan, Palmultang, Sihogyejitang, Sihosogantang, Cheongsanggyeontongtang, Sihocheonggantang, Bojungikgitang, Boheotang and Banhabaekchoolcheonmatang. In MTT assay, concentration of 80% cell survival was highest in the order of Sihosogantang, Cheongsanggyeontongtang, Sihocheonggantang, Sihogyejitang, Bojungikgitang, Galgeuntang, Ojeoksan, Boheotang, Palmultang, Galgeunhaegitang, Banhabaekchoolcheonmatang and Gamisoyosan. Formulae with more than 50% DPPH radical scavenging activity at concentrations for 80% cell survival were Sihosogantang, Cheongsanggyeontongtang, Sihogyejitang, Galgeuntang and Sihocheonggantang. Conclusions : Sihosogantang, Cheongsanggyeontongtang, Sihogyejitang, Galgeuntang and Sihocheonggantang extracts can be candidate medicines for PD, but the effect should be validated in PD models.

It is well known that the fruit of the vitamin tree (Hippophae rhamnoides L.) provides excellent anti-diabetic, antibacterial, immune regulation, anti-inflammatory, and anti-aging effects. In some countries including Europe the fruit has been added to certain foods to develop functional foods. The present research was carried out to elucidate the biological function of vitamin tree fruit powder added to fermented milk. It was found that there was an antioxidant effect of yoghurt made with vitamin tree fruit powder, and this effect was greater with increased incubation time and amount of vitamin powder, as shown by 1,1-diphenyl2-picrylhydrazyl (DPPH) and 2,2-anziobis (3-ehtylbenzothiazoline-6-sulfonic aicd) (ABTS) radical scavenging activities. The antibacterial effect of yoghurt containing vitamin tree fruit powder was shown to be effective against four pathogenic microorganisms, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonela Typhimurium. In particular, yoghurt supplemented with 5% of vitamin tree fruit powder showed the best antibacterial effect. The yogurt containing the vitamin tree fruit powder significantly inhibited the expression of the anti-inflammatory cytokines interleukin (IL)-6 (yogurt [Y] + Hippophae rhamnoides L. powder [HP] and yogurt containing 5% Hippophae rhamnoides L. powder [HPY]) and IL-1β (HP, Y + HP and HPY) in a concentration-dependent manner among tumor necrosis factor (TNF)-α, IL-6, IL-1, and induced nitric oxide synthase (iNOS). Our results clearly demonstrated that vitamin tree fruit powder could be a good functional ingredient for improving health through yoghurt manufactured with vitamin tree.
