Objectives : In this study, we examined the estrogenic activities and anti-osteo clastogenesis effects of PCE17, a mixture of PE (an extract of Puerariae Flos), and CE (an extract of Citri Unshius Pericarpium). Methods : The estrogenic effect of PCE17, PE and CE were examined by ER-β/ERE reporter gene assay and proliferation assay in 293 T and MCF-7 cells. The expression of estrogen-responsive gene and protein were checked by Real Time-PCR (RT-PCR) and Western blotting in MCF-7 cells. Inhibitory effect of PCE17, PE and CE on RANKL-induced osteoclast differentiation were evaluated by TRAP staining and RT-PCR in primary osteoclast precursors from rat bone marrow cells. Results : PCE17 and PE bind to ERs (estrogen receptors) and show estrogenic activities in 293T cells. They also stimulated the proliferation of MCF-7 cells and increased the expression of ER response gene, pS2. Tectorigenin, an active ingredient of PE, shows similar estrogenic activities in MCF-7 cells. PCE17 and CE inhibited RANKL-induced osteoclastogenesis in rat primary osteoclast precursor cells and down-regulated the osteoclast-specific genes of Nfatc1, Ctsk, and Acp5. Conclusions : In conclusion, PCE17 may have therapeutic potential in cases of menopause and osteoporosis.

Objectives : We investigated the anti-aging effects on skin with 9 Repetitive steaming and fermenting herbal composition extract (FHE). Methods : Herbal composition is comprised of Panax Ginseng, Rehmannia glutinosa, Polygonum multiflorum and Polygonatum Sibiricum. They steamed and fermented with Saccharomyces cerevisiae and Lactobacillus brevis by turns at 9 times. We measured various effects related to skin aging such as scavenging activity against free radical, cell proliferation, collagen synthesis and toxicity of 9 repetitive steaming and fermenting herbal composition extract were evaluated and compared with herbal composition extract (HE). Results : As the number of steaming and fermenting cycle increased free-radical scavenging activity were increased. But cell proliferating ratio was not increased when the number of steaming and fermenting cycle. The FHE could significantly increase the collagen synthetic ratio compared with HE treated group. And, FHE was showed no toxicity at all tested concentrations. Conclusions : The results of our study propose that FHE has good anti-aging effects on skin.

Objectives : This study aimed to investigate the synergistic effect of combining Cynanchi Wilfordii Radix extract with Humuli Lupuli Flos extract on estrogenic and anti-osteoclastogenic activity. Methods : Estrogenic effect of a mixture of Cynanchi Wilfordii Radix extract and Humuli Lupuli Flos extract (CWHL), Cynanchi Wilfordii Radix extract, Humuli Lupuli Flos extract, caudatin (an active ingredient of Cynanchi wilfordii Radix extract) and 8-prenylnaringenin (an active ingredient of Humuli Lupuli Flos extract) were examined by proliferation E-screen assay and expression of estrogen inducible gene, pS2 via Real Time-PCR (RT-PCR) in MCF-7 estrogen responsive cells. And their estrogenic activities were investigated how to modulate Estrogen receptor 𝛽 by binding affinity assay. Inhibitory effect of CWHL, Cynanchi Wilfordii Radix extract, Humuli Lupuli Flos extract, caudatin and 8-prenylnaringenin on RANKL-induced osteoclast differentiation were tested by TRAP (Tartrate-resistant acid phosphatase) staining in osteoclastogenic RAW 264.7 cells. Results : CWHL, Humuli Lupuli Flos extract and 8-prenylnaringenin accelerated the proliferation of MCF-7 and the expression of pS2 in MCF-7. CWHL, Cynanchi Wilfordii Radix extract, Humuli Lupuli Flos extract, caudatin and 8-prenylnaringenin bind to estrogen receptor 𝛽. CWHL, Cynanchi Wilfordii Radix extract, Humuli Lupuli Flos extract, caudatin and 8-prenylnaringenin inhibited RANKL-induced osteoclastogenesis in osteoclastogenic RAW 264.7. CWHL is more effective for all markers than Cynanchi Wilfordii Radix extract or Humuli Lupuli Flos extract alone. Conclusions : CWHL may a potential therapeutic agent for menopause and osteoporosis as a natural food resource. CWHL as a natural food source has therapeutic potential in cases of menopause and osteoporosis.

Objectives : From this study, we sight to identify chondro-protective and anti-inflammatory effects of Sorbi Commixtae Fructus extract and its compound, chlorogenic acid. Methods : Sorbi Commixtae Fructus were extracted by 50% ethanol. And chlorogenic acid in Sorbi Commixtae Fructus 50% extract was quantified by high performance liquid chromatography (HPLC). To investigate chondro-protective effects, we treated Sorbi Commixtae Fructus 50% ethanol extract and chlorogenic acid in TNF𝛼-activated ATDC5 murine chondrogenic cells. After 24 hours, protein level of matrix metalloproteinase-3 (MMP3) and mRNA level of matrix metalloproteinase-13 (MMP13) were measured by using ELISA or reverse transcription PCR, respectively. To examine anti-inflammatory effects, we treated Sorbi Commixtae Fructus 50% ethanol extract and chlorogenic acid in LPS-induced RAW 264.7 murine macrophages. We measured the level of inflammatory mediators, such as Prostaglandin E2 (PGE2), Interleukin-6 (IL6) by ELISA and nitric oxide (NO) by Griess reagent assay. Results : A concentration of chlorogenic acid in Sorbi Commixtae Fructus 50% ethanol extract was 3.9 mg/g. Sorbi Commixtae Fructus 50% ethanol extract and chlorogenic acid attenuated protein level of MMP3 and mRNA level of MMP13 in TNF𝛼-activated ATDC5 cells. Sorbi commixtae Fructus 50% ethanol extract inhibited the level of PGE2, IL6 and NO in LPS-activated RAW 264.7 cells in dose dependent manner, but chlorogenic acid has no anti-inflammatory effects. Conclusions : These findings demonstrated that Sorbi Commixtae Fructus 50% ethanol extract has chondro-protective and anti-inflammatory effects showing possible therapeutics to ease the symptoms related with osteoarthritis.

Human tissue undergoes aging by the oxidant damage via structural change and its physical properties. The skin aging process is well known and many evaluations have been conducted. However, studies on hair aging were relatively few and thus care for aging hair is difficult. This study aims to fabricate an aging hair and identify anti-aging effect with known ingredient in anti-aging. First of all, physical properties of aging hair of age 60s by physiologically intrinsic factors were compared to those of the hair made by various extrinsic factors such as several chemical reactions and iteration numbers of the treatments. The extrinsic aging hair of this study relates to the less amount of lipid and to the hair of perm treated once accordingly, wherein several physical properties, preferably comprise roughness and tensile strength, present a novel concept of the intrinsic aging hair. The penetration of peptide into the aging hair was leading the extrinsic hair towards more structurally directed a younger hair. In addition to the structural change, the penetration of the peptide enhanced texture and tensile strength of the aging hair. These patterns have been also found in addition of propolis. For the first time, these qualitative studies exhibit that indeed our extrinsic aging hair well describes the anti-aging efficacy as a receptor for a cross-linker and the ingredients of human hair.

This study is investigated sunscreen formulation that enhances UV absorption efficiency by UV light. Ethylhexyl methoxycinnamate (OMC) is one of the most common UV filters. Many studies have been conducted about photostability of OMC. It is well known that under the UV exposure, trans-OMC could turn to cis-OMC, or produce various photoproducts including its dimers. Those chemical structure changes were understood as the reason of a decrease in UV absorption efficiency upon UV exposure. However, it was found that OMC and isoamyl p-methoxycinnamate (IMC) could even enhance its UV absorption efficiency when it was exposed to UV light in an environment similar to actual use. In order to develop sunscreen formulation that enhances UV absorption efficiency by UV light, emollient with high polarity and compatibility should be avoided from the formular. Those emollient seemed to prevent OMC or IMC from producing photoproducts under UV light. Finally, a sunscreen formulation (UV sensing SPF boosting formular) enhancing UV absorption efficiency by UV was developed by the UV activated SPF boosting technology, and the effect of the sunscreen was evaluated. in vitro SPF of the sunscreen was increased from 50.69 to 72.33 when it was exposed to UV light and its in vivo SPF (53.7) was 56.10% higher than that of the control sunscreen (below 34.4).
