In the course of screening for substances inhibiting apoptosis of U937 human leukemia cells induced by etoposide ($10\;{\mu}g/ml$), Forsythiae fructus, which showed a high level of inhibition, was selected. The regulating compounds were purified from the ethyl acetate extract by silica gel column chromatography and HPLC. The active substance was purified and identified as rengyolone by spectroscopic methods. This compound showed inhibitory activity on caspase-3 induction, a major protease of the apoptosis cascade, with an $IC_{50}$ value of $38.96\;{\mu}M$ after 8 h of etoposide treatment in U937 cells. The expression level of caspase-3 and poly(ADP-ribose) polymerase (PARP) were dose-dependently inhibited by the compound, suggesting that rengyolone inhibits etoposide-induced apoptosis via downregulation of caspases.

Cutaneous microvasculature plays a critical role in age-associated skin changes. A considerable reduction of number and size of vessels has been observed in the upper dermis of elderly skin. Forsythiae fructus (FF), the dried fruit of plant Forsythia suspensa (F. suspensa), has been traditionally used as an herbal medicine to treat inflammatory diseases and bacterial diseases. However, its regulatory effect on angiogenic responses has not been elucidated in skin. Therefore, we analyzed secretory profiles upon treatment of FF extract using array designed to detect angiogenesis-associated mediators in human keratinocytes. Because keratinocyte-derived VEGF (vascular endothelial growth factor) has been regarded as a potent factor for new microvasculature under the epidermis, we further investigated the effect of FF extract on VEGF production. We observed that the VEGF expression of mRNA and protein level was increased by about 2 folds in a dose-dependent manner after FF extract treatment. In signaling experiments, FF extract induced rapid p38 MAPK activation within 5 min, and the activation was totally abrogated by pretreatment with a p38 MAPK specific inhibitor. The FF-induced VEGF upregulation was also significantly attenuated by a p38 MAPK inhibition. Taken together, FF extract induces VEGF production via p38 MAPK activation in human epidermal keratinocytes. These novel findings suggest that FF is useful as a potential agent with pro-angiogenic activity and may help to improve age-dependent reduction of the microvasculature in aged skin or to heal skin wound.

To investigate the antimicrobial effect of the Patrinia scabiosaefolia extracts against food-borne pathogens, we extracted the P. scabiosaefolia with methanol at room temperature and the fractionation of the methanol extracts was carried out by using petroleum ether, chloroform, ethyl acetate, and methanol, respectively. The antimicrobial activity of the P. scabiosaefolia extracts was determined by using a paper disc method against food-borne pathogens and food spoilage bacteria. The ethyl acetate extracts of P. scabiosaefolia showed the highest antimicrobial activity against Escherichia coli and Shigella sonnei. Synergistic effect in inhibition was observed when P. scabiosaefolia extract was mixed Forsythiae fructus extract as compared to each extracts alone. Finally, the growth inhibition curves were determined by using ethyl acetate extracts of P. scabiosaefolia against Staphylococcus epidermidis and Shigella sonnei. The ethyl acetate extract of P. scabiosaefolia had strong antimicrobial activity against S. sonnei at the concentration of 4,000 ppm. At this concentration, the growth of S. Sonnei was retarded more than 72 hours and up to 48 hours for S. epidermidis. These results suggest that the ethyl acetate extracts of P. scabiosaefolia can be used for the efficient material against the growth of S. epidermidis and S. sonnei.

Objectives : The purpose of this study is 1) to explore the general tendency of the herbs or herbal formula for acne treatment in clinical practice 2) and to provide a basis for explaining the principles of acne treatment in Korean Medicine in order to make patients understand more easily based on pharmacological mechanism by analyzing the herbs or herbal formula using for acne treatment in clinical practice. Methods : In the domestic databases (Oriental medicine Advanced Searching Integrated System-OASIS, Korean Traditional Knowledge Portal-KTKP, National Discovery for Science Leader-NDSL, Research Information Sharing Service-RISS), we selected among the papers published using search terms related to "acne". Reports related to sasang constitutional medicine were excluded and a total of 23 papers were finally selected. Results : 29 prescriptions were retrieved from 23 papers. Chungan-tang (淸顔湯) notified formulas ranked first by Cheongsangbangpung- tang (淸上防風湯), Hwangnyeonhaedok-tang (黃連解毒湯), Dangguijakyaksan (當歸芍藥散) and Bipachungpe-eum (枇杷淸肺飮). Commonly used herbs are Forsythiae Fructus (連翹), Scutellariae Radix (黃芩), Gardeniae Fructus (梔子), Ligustici Rhizoma (川芎), and Angelicae Gigantis Radix (當歸). In most patients with inflammatory lesions or excessive flushing, exterior-releasing medicinal (解表藥) and heat-clearing medicinal (淸熱藥) were mainly prescribed for acne treatment, while in patients with acne accompanied hyperkeratinization, Excess sebum secretion, Dysmenorrhea or indigestion, qi-tonifying medicinal (補氣藥) or blood-tonifying medicinal (補血藥) were mainly used. KAGS (Korean Acne Grading System) was the most commonly used method for acne severity assessment. Conclusions : These findings suggest that the herbs or herbal formula for acne treatment in Korean Medicine is prescribed differently according to the cause and symptoms of acne in a unique way for control the whole body balance. Also, our findings could provide a basis for explaining the principles of acne treatment in Korean Medicine in order to make patients understand more easily based on pharmacological mechanism in clinical practice.

This study was carried out to investigate the residual sulfur dioxide residues ($SO_2$) in commercial medicinal herbs in Korea in 2013. Among a total of 116 samples of 11 different kinds of herbs, 71 samples (11 Kinds) were domestic, and 45 samples (10 Kinds) were imported. The residual contents of $SO_2$ in the samples were determinated by a modified Monier-Williams method. Of the 116 samples, 6 samples (5.2%, 4 Kinds) failed to meet the regulations for sulfur dioxide residues of KFDA in medicinal herbs. Among 6 unsuitable samples, 1 samples (1.4%) were domestic, and 5 samples (11.1%, 3 Kinds) were imported. The highest amount of sulfur dioxide residues was 1546.3 mg/kg (Lycii Fructus) in the domestic samples. Regardless of region, $SO_2$ contents were not found at Anemarrhenae Rhizoma, Citri Unshius Pericarpium, Eucommiae Cortex, Forsythiae Fructus, Gardeniae Fructus, Leonuri Herba and Lonicerae Folium et caulis. These data will be used as a basic data for the future legislation on the regulation and control of sulfur dioxide of herbal medicines.
