  • In modern oriental medicine, bee venom therapy is being used for aqua-acupuncture to relieve pain and to cure inflammatory diseases such as rheumatoid arthritis, osteoarthritis, and gout. Bee venom therapy has been processed and reported in many experimental studies, with regard to its effects on pain alleviation, anti-inflammation, removal of fever, anti-convulsion, suppression of tumor and immunity strengthening, etc., however, its mechanism of action, molecular targeting on prostaglandin $E_2$ ($PGE_2$) production and telomere length regulation in human cancer remains unclear. In this study, we investigated the effect of bee venom on the levels of cyclooxygenases (COXs) and telomere regulatory components of A549 human lung cancer cells. Bee venom-induced anti-proliferative effects of A549 cells were associated with the inhibition of human telomerase reverse transcriptase (hTERT) as well as human telomerase RNA (hTR), transcription factor c-myc and the activity of telomerase. In addition, bee venom treatment markedly decreased the levels of COX-2 mRNA and protein expression without significant changes in the expression of COX-1, which was correlated with a decrease in $PGE_2$ synthesis. Taken together, these findings provide important new insights into the possible molecular mechanisms of the anti-cancer activity of bee venom.

  • This study was conducted to determine the effect of extract of Cervi pantotrichum cornu on human sperm motility, Four different types of media were prepared such as plain Ham's F-10 medium(control medium), control medium containing 0.3% bovine serum albumin(BSA)(medium A), control medium containing the extract of Cervi pantotrichum cornu aqua-acupuncture medium(medium B) and medium B containing 0.3% BSA(medium C). Human semen were washed and divided into 4 fractions and sperm were cultured in those medium for up to 72 hours at 37$^{\circ}C$ in a humidified atmosphere of 5% $CO_2$ in air. A total twenty eight semen samples including 14 normozoospermia and 14 asthenospermia were used for this study. In normozoospermia group, motility of control medium and medium A, B and C were 4.1%, 1.3%, 64.5%, and 77.1%, respectively after 24 hours of incubation, and were 0.0%, 0.0%. 8.8% and 44.9%, respectively after 48 hours of incubation. In asthenospermia group, motility of control medium and medium A, B and C were 2.0%, 2.2%, 58.3% and 85.1%, respectively after 24 hours of incubation, and decreased to 0.0%, 0.2%, 5.8% and 29.6%, respectively after 48 hours of incubation. In both groups, highest sperm motility was observed in medium C group when compared with other media. Furthermore motile sperm were found in medium C after 72 hours of incubation while no motile sperm was observed in the other media. Therefore it could be concluded that the extract of Cervi pantotrichum rornu affects on the human sperm motility.
