Abstract
Objective : The purpose of this study was investigation how the bee venom(BV) prevents inflammation in human cell. Methods : we induced inflammation on human synoviocyte cell by lipopolysaccharide(LPS) and sodium nitroprusside(SNP), treated the bee venom and melittin on this cell, surveyed the expression of Nisotric oxide(NO), inducible nitric oxide synthase(iNOS), Cyclooxygenease-2(COX-2), cytolic phospholipase $A_2(cPLA_2)$, Prostaglandin $E_2(PGE_2)$ and nuclear factor-${\kappa}B$(NF-${\kappa}B$), and got below conclusions. Results : Compared with control 1. Expressions of LPS-induced $PGE_2$(BV 1, $5{\mu}g/m{\ell}$) and SNP-induced PGE2(BV 0.5, 1, $5{\mu}g/m{\ell}$)were decreased significantly. 2. Expressions of LPS-induced NO(BV 0.5, 1, $5{\mu}g/m{\ell}$) and SNP-induced NO(BV 1, $5{\mu}g/m{\ell}$)were decreased significantly. 3. Expressions of LPS-induced COX-2(BV 1, $5{\mu}g/m{\ell}$) and SNP-induced COX-2(BV $5{\mu}g/m{\ell}$)were decreased significantly. 4. Expressions of LPS-induced iNOS(BV 0.5, 1, $5{\mu}g/m{\ell}$) and SNP-induced iNOS(BV $5{\mu}g/m{\ell}$) were meanless by all dose. 5. Expressions of LPS-induced $cPLA_2$(BV 1, $5{\mu}g/m{\ell}$) and SNP-induced cPLA2(BV 1, $5{\mu}g/m{\ell}$)were decreased significantly. 6. Expressions of LPS-induced NF-${\kappa}B$(BV $5{\mu}g/m{\ell}$, melittin $5{\mu}g/m{\ell}$) and SNP-induced NF-${\kappa}B$(BV 0.5, 1, $5{\mu}g/m{\ell}$, melittin 5, $10{\mu}g/m{\ell}$)were decreased significantly. 7. Expressions of LPS-induced NF-${\kappa}B$ binding activity (BV $1{\mu}g/m{\ell}$, melittin $5{\mu}g/m{\ell}$, melittin $5{\mu}g/m{\ell}$+ DTT 20mM) were decreased significantly. Conclusion : The bee venom treatments on synoviocyte showed significant changes in LPS and SNP induced NO, iNOS, COX-2, cPLA2, PGE2 and NF-${\kappa}B$, these results suggest that bee venom is effective to inflammations and establish the process of bee venom therapy, so we expect active use of bee venom to control the inflammation.
