  • Purified bee venom was collected from colonies of honeybees (Apis mellifera L.) using a bee venom collector under sterile conditions and then purified under strict laboratory conditions. Purified bee venom contained $63.9{\pm}5.4%$ melittin, $10.9{\pm}1.6%$ phospholipase A2, and $2.3{\pm}0.3%$ apamin. Purified bee venom has various anti-bacterial, anti-inflammatory and immunostimulating effects. In this study, we evaluated purified bee venom which are mammary gland cells, MAC-T cells are used to increase the synthesis of milk protein. Purified bee venom promoted the proliferation of MAC-T cells at concentrations below $1{\mu}g/mL$, but cytotoxicity at $10{\mu}g/mL$ and above. As a result of the increase in the synthesis of ${\beta}-casein$, a milk protein after treatment with MAC-T cells at a concentration of the bee venom without cytotoxicity, the ${\beta}-casein$ content in the cell culture was increased when treated at a concentration of 1 ng/mL or more. In addition, it was confirmed that purified bee venom significantly increased the expression of bovine ${\beta}-casein$ (bCSNB) mRNA, a ${\beta}-casein$ synthesis gene, at a concentration of 1 ng/mL or more. These results suggest that purified bee venom can be used to increase the production of livestock by ultimately increasing the expression of milk protein.

  • The aim of the study was performed to examine the anticariogenic potential of purified bee venom (Apis mellifera L., PBV) collected using bee venom collector from cariogenic bacteria, Streptococcus mutans, Streptococcus sanguis, Porphyromonas gingivalis, and Fusobacterium nucleatum. The anticariogenic effect of purified bee venom was evaluated by agar well diffusion method, minimum inhibitory concentraion (MIC), minimum bactericidal concentration (MBC), and postantibiotic effect (PAE). The human lower gingiva epithelial cell cytotoxicity of purified bee venom was also evaluated. Purified bee venom exhibited significant inhibition of bacterial growth of S. mutans, S. sanguis, P. gingivalis, and F. nucleatum with MIC value of 0.68, 0.85, 3.49, and $2.79{\mu}g/ml$, respectively. The MBC value of purified bee venom against S. mutans, S. sanguis, P. gingivalis, and F. nucleatum was 1.34, 1.67, 8.5, and $6.8{\mu}g/ml$. Furthermore, the results of PAE values against S. mutans, S. sanguis, P. gingivalis, and F. nucleatum showed the bacterial effect with 3.3, 3.45, 2.0, and 2.0. The concentration below 1 mg/ml of purified bee venom had no cytotoxicity in the human lower gingiva epithelial cell. These results suggested that purified bee venom have great potenial as anticariogenic agents.

  • Clostridium perfringens, Salmonella thyphimurium and S. Montevideo isolated from the intestines of dead broiler chickens in Korea were tested for antibacterial effects to purifed bee venom. Purified bee venom from Apis mellifera L. has been used as natural antimicrobial compounds in pigs, cows, dairy cattle and chicken farms in Korea. To investigate antibacterial effect of purified bee venom was evaluated by agar well diffusion method, minimum inhibitory concentraion (MIC), minimum bactericidal concentration (MBC), and postantibiotic effect (PAE). Purified bee venom exhibited significant inhibition of bacterial growth of C. perfringens, S. thyphimurium and S. Montevideo with MIC value of 0.85, 0.68 and $0.69{\mu}g/mL$, respectively. The MBC value of purified bee venom against C. perfringens, S. thyphimurium and S. Montevideo were 3.33, 2.66 and $2.86{\mu}g/mL$. Furthermore, the results of PAE values against C. perfringens, S. thyphimurium and S. Montevideo showed the bacterial effect with 3.5, 4.0 and 3.5 hr. Stability of pufifed bee venom at acidity from pH 1 to pH 8 for 24 hr was the antibacterial activity for C. perfringens, S. thyphimurium and S. Montevideo and melittin contents. Also purified bee venom processed through the heating for 15 min, there was no signification loss of the antibacterial activity and melittin at below $100^{\circ}C$. These results obtained in this study suggest that purified bee venom might be utilized as a feed additive in poultry diets.

  • The stability comparison tests on purified bee venom (PBV) and bee venom melittin (BVM) in different conditions of temperature, solvent, and concentration were studied. High purity BVM (98.2 %) was separated from PBV by prep-HPLC (column, C4) and used to stability tests in aqueous phase. The stability of the PBV has been increased in the saline solution, while BVM was reduced. In distilled water, the stability of PBV has been reduced, while BVM showed an increasing result. As a result, the appropriate conditions for maintaining the long term stability of BVM were found to be the low temperature (4 ℃), distilled water, and concentration (1.0 mg/mL).

  • We investigated whether purified bee venom increases the enzymatic activity of the alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). ADH and ALDH assay were tested by in vitro kits. The purified bee venom was assayed by ultra performance liquid chromatography, The contents of melittin, apamin and phospholipase A2, as main component of purified bee venom, were 63.9%, 2.3%, and 10.9%, respectively. The ADH and ALDH acitivity of purified bee venom(at 1mg/ml) were $88.6{\pm}7.34%$ and $94.6{\pm}0.57%$, respectively compared with positive control at 2mg/ml. These results showed that purified bee venom induces the activity of ADH and ALDH which reduce the aldehyde concentration in the blood, suggesting the possibility of purified bee venom as resource of medicine or functional beverage for hangover relieving.

  • This study was performed to examine the skin phototoxicity of purified bee venom (Apis mellifera L.) collected using bee venom collector. To confirm whether the gel containing purified bee venom (BV gel) causes photototoxicity when used for the skin medicinal products, phototoxicity testing was conducted using guinea pig models. The BV gel (0.1 ml/site) was administered transdermally to guinea pigs. 8-MOP was used to introduce positive control response. After administration, the guinea pigs were irradiated with UVA ($15J/cm^2$) with doses based on standard phototoxicity study guidelines. In the weight measurement and clinical observation, BV gel groups didn't show any significant changes compared with control group. BV gel groups did not show any symptoms such as erythema and edema formation of skin. This study demonstrated that BV gel has promising potential external treatment for topical uses that do not induce significant levels of skin phototoxicity.

  • The aim of the current study was to examine genotoxicological safety of purified bee venom (Apis mellifera L.) The bacterial reverse mutation in Salmonella typhimurium (TA100, TA1535, TA98, and TA1537) and Escherichia coli (WP2 uvrA) were evaluated with purified bee venom at concentrations of 0, 1.5, 5, 15, 50, 150, and $500{\mu}g/plate$. Purified bee venom was negative in Ames test with both in the presence and absence of rat liver microsomal enzyme. According to these results, we concluded that purified bee venom did not cause bacterial reverse mutation. The safety of the purified bee venom at practical doses needs to be further evaluated in in vivo genotoxicity assays.

Phospholipase $A_2$ was showed single band at molecular weight 17,000 in SDS-PAGE and bee venom was showed two band at molecular weight 17,000 and under molecular weight 6,500 in SDS-PAGE. 2. During 70 days after hen immunized with bee venom and phospholipase $A_2$, antibodies(anti-bee venom IgY) to bee venom were showed poor ELISA value in egg yolk, but antibodies$(anti-Phospholipase\;A_2IgY)$ to phospholipase $A_2$ in egg yolk were increased ELISA value from 8 days or 15 days and found maximum ELISA value at 42 days. Also after booster at 49 days, ELISA value of anti Phospholipase $A_2\;IgY$ in egg yolk was supported at optical density(O.D) 1.0 level, continuously. 3. Titer of phospholipase $A_2\;IgY$ was showed 1: 32,000. 4. In double immunodiffusion test to phospholipase $A_2$ after double dilution of anti-phospholipase $A_2\;IgY$, only precipitation line was made in 1:1 dilution well of anti-Phospholipase $A_2\;IgY$. But In immunodiffusion test to anti-phospholipase $A_2\;IgY$ after double dilution of phospholipase $A_2$, Precipitation line to 250ul/ml well of phospholipase $A_2$ was showed. In double immunodiffusion test to bee venom(1mg/ml) after double dilution anti-phospholipase $A_2\;IgY$, all well without 1:32 dilution well were showed strong precipitation line. 5. In dot bloting test to anti-phospholipase $A_2\;IgY$ after diluting bee venom(0.5mg/ml), dot bloting color was showed clearly to $1/100(5{\mu}g/ml)$ in bee venom.

  • Objectives: This study was performed to analyse the effects of Sweet Bee Venom(SBV-purified melittin supported by G&V Co., the major component of honey bee venom) on the respiratory system in rats. Methods: All experiments were conducted at Biotoxtech Company, a non-clinical studies authorized institution, under the regulations of Good Laboratory Practice(GLP). Male rats of 5 weeks old were chosen for this study and after confirming condition of rats was stable, SBV was administered in thigh muscle of rats in 0.175, 0.35 and 0.7 mg/kg dosage. And checked the effects of SBV on the respiratory system using the whole body plethysmography. And respiratory rate, tidal volume and minute volume of rats were checked after administered SBV (melittin). Results: 1. In the measurement of respiratory rate, there were not observed any significant differences compared with control group. 2. In the measurement of tidal volume, there was not observed any significant differences compared with control group. 3. In the measurement of minute volume, 0.35mg/kg dosage group showed significant differences compared with control group. But we estimated that this result was caused by individual differences. Conclusions: Above findings suggest that SBV seems to be safe treatment in the respiratory system of rats. And further studies on the subject should be conducted to yield more concrete evidences.
