Gaoioiga Fa'aletino ole Isovitexin

Sini:JNK1 jnk2 NF- κ B

Suʻesuʻega in vitro:isovitexin e taofia ai le faaleagaina o le oxidative LPS e ala i le taofia o le gaosiga o le intracellular ROS, ma faʻavaivaia ai foi le aʻafiaga o le H2O2 i luga ole cell viability.O loʻo i ai le LPS (2 μ Isovitexin (0-100 g / ml) μ G / ml) e leai se cytotoxicity i le mata 264.7 sela, ae 200 μG / ml isovitexin na faʻaalia ai le cytotoxicity taua.Isovitexin (25,50) μG / ml) faʻasaina LPS faʻaosoina TNF-α, Faʻateleina tulaga ole IL-6, iNOS ma COX-2.Isovitexin (25,50) μG / ml) na faʻalavelaveina foi I i le mata 264.7 sela κ B α Phosphorylation ma degradation, lea e ogatasi ma le aafiaga o le JNK1 / 2 inhibitor [1].

Suʻesuʻega i vivo:isovitexin (50 ma le 100 mg / kg, IP) na mafua ai le faʻaitiitia o suiga o le histopathological i vaega o le mama ma faʻaitiitia ai le numera o sela inflammatory i le LPS faʻaosoina isumu.Heteroeosinophils (50 ma 100 mg / kg, IP) faʻaititia TNF e- α Ma IL-6 gaosiga, ROS gaosiga, MPO ma MDA anotusi, faʻateleina le SOD ma le GSH, ma puipuia LPS faʻaosoina mumū ma faʻamaʻi faʻamaʻi i le LPS faʻaosoina Ali isumu.Ma faʻamalosia lelei le faʻaalia o le porotini o le iNOS ma le COX-2 [1].Isovitexin (25,50, 100 mg / kg) faʻaititia le fua o le ola o le LPS / D-gal faʻaoso manuʻa ate i isumu i se fua faʻalagolago.Isovitexin na faʻalavelaveina foi le NF-κ B ma faʻatulafonoina LPS / D-gal faʻaosoina Nrf2 ma HO-1 i isumu [2].

Su'ega sela:ole fa'aogaina ole sela na fa'amauina ile MTT assay.264.7 sela mataʻutia na tui i luga o le 96 lelei ipu (1) × 104 sela / vaieli) ma faʻatasi ai ma faʻasalalauga eseese o le isovitexin (faʻasalaga mulimuli: 0-200) μG / ml) ma le LPS (2 μG / ml) mo le 24 itula.E le gata i lea, faʻaaoga IV (25 poʻo 50 μG / ml) faʻapipiʻi sela mo le 1 itula, ona faʻaopoopoina lea o le H 2O 2 (300) μ M). A maeʻa itula 24, faʻaopoopo le MTT (5 mg / ml) i le. sela ona fa'a'ofuina lea mo le 4 itula [1].

Fa'ata'ita'iga manu:isumu [1] ina ia faʻavaeina faʻataʻitaʻiga Ali, na vaevaeina faʻafuaseʻi mice i vaega e 6: pulea (saline), naʻo le isovitexin (100 mg / kg, faʻamavae i le 0.5% DMSO), naʻo le LPS (0.5 mg / kg, faʻamavae i le saline. ), LPS (0.5 mg / kg) + isovitexin (50 poʻo 100 mg / kg) ma LPS (0.5 mg / kg) + dexamethasone (DEX, 5 mg / kg, faʻamavae i le saline).Isovitexin poʻo DEX (5 mg / kg) isovitexin na faʻatinoina.A maeʻa ona faʻaalia i le isovitexin poʻo le DEX mo le 1 itula, na faʻamaʻi ai isumu i le eter ma LPS na faʻatonuina i totonu (i) e faʻaoso ai manuʻa mama.O manu na faʻaumatia i le 12 itula talu ona maeʻa le faʻaogaina o le LPS.O le mea lea, o le sua o le bronchoalveolar lavage (BALF) ma faʻataʻitaʻiga o le mama na seleseleina e fua ai le maualuga o le cytokine;Tupulaga ROS;Galuega SOD, GSH, MDA ma MPO;Ma o le faʻaaliga o COX-2, iNOS, HO-1 ma Nrf2 polotini [1].
