  • Bee venom has been used as to prevent and treat bovine mastitis as natural antimicrobial compounds in some dairy cattle farms in Korea. It is needed to determine the residual of bee venom in milks of dairy cattle treated with bee venom. Since bee venom is not approved as a raw material for animal drugs, the preprocessing method to detect bee venom residual in milk and the tolerance limit for its residue has not been established yet in Korea. Therefore, the purpose of this study was to develop pre-processing method not affecting major component of bee venom for detection of its residue in milks using ultra-high performance liauid chromatography (UHPLC). In addition, bee venom residue was also analyzed in milk samples of dairy cattle treated for mastitis with bee venom using UHPLC with the developed pre-processing method in this study. As a result, melittin, histamin and phospolipase A2, the major components of bee venom, were all detected by UHPLC with the pre-processing method developed in this study. The results of this study suggest that the pre-processing method developed in this study can be useful to detect bee venom residue in dairy cattle milk. We also found that no bee venom residues were detected in milk samples collected from dairy cattle treated with bee venom after 1 and 3 days, respectively.

  • To investigate the possible molecular mechanism (s) of bee venom as a candidate of anti-cancer drug, we examined the effects of the compound on the growth of human lung carcinoma cell line A549. Bee venom treatment declined the cell growth and viability of A549 cells in a concentration-dependent manner, which was associated with induction of apoptotic cell death. Bee venom down-regulated the levels of anti-apoptotic genes such as Bcl-2 and Bcl-XS/L, however, the levels of Bax, a pro-apoptotic gene, were up-regulated. Bee venom treatment induced not only tumor suppressor p53 but also cyclin-dependent kinase inhibitor p21WAF1/CIP1 expression in a dose-dependent manner. Furthermore, bee venom treatment induced the down-regulation of telomerase reverse transcriptase mRNA and telomeric repeat binding factor expression of A549 cells, however, the levels of telomerase-associated protein-1 and c-myc were not affected. Taken together, these findings suggest that bee venom-induced inhibition of human lung cancer cell growth is associated with the induction of apoptotic cell death via regulation of several major growth regulatory gene products, and bee venom may have therapeutic potential in human lung cancer.

  • Due to low cost, low-power, and scalability, ZigBee is considered an efficient wireless AMR infrastructure. However, these characteristics of ZigBee can make the devices more vulnerable to unexpected error environments. In this paper, a fault-tolerant wireless AMR network (FWAMR) is proposed, which is designed to improve the robustness of the conventional ZigBee-based AMR systems by coping well with dynamic error environments. The experimental results demonstrate that the FWAMR is considerably fault-tolerant compared with the conventional ZigBee-based AMR network.

  • Bee Venom therapy, as bee honey has long contributed to human life as a valuable fancy food since human history began. It can be found in the literature back up to a thousand years as a form of therapy for management of apin of various origin. Even to the present, there are some physicians and medical personnel who believe in the effects of bee sting therapy throughout the world. However Bee Venom therapy remains somewhat controversial and there are very few controlled studies available to guide clinical practice. We administered apitherapy(Bee venom therapy) against pain of musculoskeletal origin in thirty one patients from october 1988 to october 1990 and got successful results in seventy one percent of patients. Our results suggest that Bee Venom therapy can be one of the methods for conquering pain caused by true inflamation.

  • This study was designed to study on major components of various Bee Venom(Bee Venom by electrical stimulation in Korea; K-BV I, Bee Venom by Microwave stimulation in Korea; K -BV II, 0.5rng/ml, Fu Yu Pharmaceutical Factory, China; C-BV, 1mg /ml, Monmouth Pain Institute, Inc., U.S.A.; A-BV) using Electrophoresis. The results were summarized as follows: 1. In 1:4000 Bee Venom solution rate, the band was not displayed distinctly usmg Electrophoresis. But in 1: 1000, the band showed clearly. 2. The results of Electrophoresis at solution rate 1:1000, K-BV I and K-BVII showed similar band. 3. The molecular weight of Phospholipase $A_2$ was known as 19,000 but its band was seen at 17,000 in Electrophoresis. 4. Protein concentration of Bee Venom by Lowry method was different at solution rate 1:4000 ; C-BV was $250{wmu}g/ml,\;K-BV\;I\;was\;190{wmu}g/ml,\;K-BVII\;was\;160{wmu}/ml\;and\;C-BV\;was\;45{wmu}/ml5$. Electrophoresis method was unuseful for analysis of Bee Venom when solution rate is above 1:4000 but Protein concentration of Bee Venom by Lowry method was possible. These data from the study can be applied to establish the standard measurement of Bee Venom and prevent pure bee venom from mixing of another components. I think it is desirable to study more about safety of Bee Venom as time goes by.

  • Bee venom acupuncture (BVA), as a kind of herbal acupuncture, involved injecting diluted bee venom into acupoints and is used for pain, osteoarthritis and rheumatoid arthritis patients. BVA is growing in popularity, especially in Korea, and is used primarily for pain relief in many kinds of diseases. However, the effect of bee venom anti-inflammatory related action in lipopolysaccharide (LPS) induced chondrocyte stress have not been reported yet. The aim of this study was to investigate the effect of bee venom of cell viability and inflammatory cytokine in rat articular chondrocyte cultures stimulated with lipopolysaccharide. Inflammation was induced in rat chondrocytes by treatment with $10{\mu}g/m{\ell}$ LPS. The change of cell viability were decreased in chondrocytes after treatment with lipopolysaccharide. The cell viability revealed that BV exerted no significant cytotoxicity in the rat chondrocyte. Bee venom inhibited decreased cell viability in the presence of lipopolysaccharide ($10{\mu}g/m{\ell}$) in a dose dependent manner(0.1, 0.5, 1.0 and $5.0{\mu}g/m{\ell}$) at bee venom(p<0.05). Tumor necrosis factor (TNF)-${\alpha}$ production in the presence of lipopolysaccharide($1{\mu}g/m{\ell}$) was also inhibited in a dose dependent manner (p<0.05 from bee venom $0.1{\mu}g/m{\ell}$). Interleukin (IL)-6 production in the presence of lipopolysaccharide ($10{\mu}g/m{\ell}$) was inhibited as well (p<0.05 at bee venom 0.1, 0.5, 1.0 and $5.0{\mu}g/m{\ell}$, respectively). Our results demonstrate that bee venom was a anti-inflammatory agent of chondrocytes. Bee venom may exert its anti inflammatory effects through inhibition of TNF-${\alpha}$ and IL-6 synthesis, and may then pain relief and reduce the articular destruction.
