Royal jelly composes of many components, especially protein. Protein is a major factor which cause allergy. We focused on water soluble royal jelly (WSRJ) that was removed allergy - inducing protein. 10-hyroxy-2-decenoic acid content of WSRJ is 2.42 g/100 g, which is double compared to that of lypophilized RJ. To further access WSRJ as a cosmetic ingredient and potential external treatment for topical use, we investigated its ability to inhibit tyrosinase activity and melanin biosynthesis on melanogenesis in B16F1 melanoma cells. We found that WSRJ increased the cell viability in B16F1 melanoma cell and WSRJ (1~10 mg/ml) inhibited melanin synthesis in with 10 nM a-melanocyte-stimulating hormone (a-MSH) for 48 h. WSRJ inhibited direct tyrosinase activity, which decreased melanin synthesis in a-MSH stimulated B16F1 melanoma cells. Thease findings suggest that WSRJ induces the down regulation of melanogenesis by inhibiting tyrosinase activation

Propolis possesses antimicrobial, anti-inflammatory, anaesthetic and immunostimulating activities. The aim of this study was to evaluated chemical composition and in vitro anti-Helicobacter pylori activity of eight propolis ethanolic extracts form different region in Korea. The chemical composition of eight Korean propolis was investicated by absorption spectrophotomety and UHPLC. Total penolic and total flavonoids content ranged between $21{\pm}1.5$ and $31{\pm}1.8$ gallic acid g/100 g and $7.2{\pm}0.9$ and $24.4{\pm}1.9$ quercetin g/100 g, respectively. The p-coumaric acid as standard components content ranged between $0.29{\pm}0.00$ and $2.34{\pm}0.02mg/g$ using UHPLC. Cinnamic acid content between $0.43{\pm}0.00$ and $1.33{\pm}0.01mg/g$. 80% ethanolic extract of propolis against H. pylori was evaluated by using the disc diffusion method. Ethanol was used as a control. Mean diameters of H. pylori growth inhibition using $10{\mu}g/mL$, $50{\mu}g/mL$ or $100{\mu}g/mL$ ethanol propolis per disc were 0, ranging from 0.9 to 2.1 mm and from 1.9 to 3.5 mm, respectively. In conclusion, variation in the chemical composition of Korean propolis were mainly due to the difference in the preferred regional plants visited by honeybees. Also Korean propolis possesses considerable antibacterial activity against H. pylori. There was not confirmed a correlation between the chemical composion contens and anti-H. pylori effect. The potential of propolis in the prevention or treatment of H. pylori infection is worth further extensive evaluation.

This study was performed to examine the antigenic potential of purified bee venom (Apis mellifera L., PBV) collected using bee venom collector. Antigenic potential of PBV was examined by active systemic anaphylaxis (ASA) in guinea pigs. PBV was subcutaneously administered at 0.025 and 0.05 mg/kg and also as a suspension with adjuvant (Freund's complete adjuvant, FCA). Ovalbumin (OVA) as a suspension with adjuvant was used to introduce positive control response. In the weight measurement and clinical observation, experimental groups didn't show any significant changes compared with control group. In the autopsy of body, the abnormalities of lung were detected only in the positive control. In the ASA test, experimental groups didn't show any symptoms of anaphylaxis like piloerection, hyperpnea and staggering gait. These results suggested that PBV didn't have antigenic potential in guinea pig.
