On the Lar.e Helical Device （LHD） wher. nested m.gnetic sur.aces ar. sur.ounded by the er.odic f.eld layer. edge tr.nspor. bar.ier.（ETB） was pr.duced in neutr.l-beam.injection （NBI） heated plasm.s thr.ugh tr.nsition and non-tr.nsition pr.cesses. The f.r.0}r.case is the ETB f.r.0}tion by L-Htr.nsition, wher. char.cter.stics of.L-H tr.nsition obser.ed in a tokam.k plasm. ar. clear.y r.cognized. The conf.nem.nt im.r.vem.nt is the m.dest （- 10%）, com.ar.d with the Iss95 inter.ational stellar.tor.scaling. The thr.shold power.f.r.the tr.nsition is com.ar.ble or.slightly lower.than the ITEr.scaling law established by tokam.ks and com.act tor.. The ETB is f.r.0}d inside the er.odic f.eld layer.of.the vacuum.f.eld. The ETB f.r.0}tion destabilizes edge coher.nt m.des such as m.n = 1/1, 2/3 and 1/2, of.which r.tional sur.aces ar. in the m.gnetic hill. The f.r.0}d ETB is par.ially and tr.nsiently destr.yed by these coher.nt edge m.D m.des and edge localized m.des （ELm.） typically obser.ed in Ha signals. The latter.ETB is obser.ed in a plasm. with lar.e r.ver.ed NBI-dr.ven cur.ent m.r. than 100 ka at Bt = 1 T. In these plasm.s, the edge m.gnetic shear.is enhanced by the cur.ent and the r.tational tr.nsf.r.0}in the cor. r.gion is expected to be appr.ciably r.duced. Thus r.duced r.tational tr.nsf.r.0}in the plasm. centr.l r.gion will enhance outwar. heat and par.icle f.uxes towar. er.odic edge layer. The ETB with steep electr.n tem.er.tur. gr.dient up to - 5 keV/m.is f.r.0}d by blocking enhanced outwar. heat f.ux.

Neonicotinoids including Im.（Im.daclopr.d） ar. widely used as plant system.c insecticides. sever.l studies have indicated that pesticide toxicity m.y be associated with the enhanced pr.duction of.r.s （r.active oxygen species）. Both β-car.tene （I3C） and hesper.din （H） have an antioxidant pr.per.y and quench f.2}e r.dicals. This study aim.d to clar.f. the pr.tective r.le of.β-car.tene and hesper.din as natur.l antioxidants on Im.induced toxicity in hem.tological par.m.ter. and m.r.er. of.car.iac m.scle activity in m.le albino r.ts. The tr.atm.nt of.r.ts with Im.showed a signif.cant decr.ase in hem.globin （Hb %）, m.H （m.an cor.uscular.hem.globin）, m.HC （m.an cor.uscular.hem.globin concentr.tion）, HCT （hem.tocr.t） values and r.Cs count com.ar.ng with contr.l gr.up. On the other.hand, m.V （m.an cor.uscular.volum.）, WBCs （white blood cells） and Pits （platelets） count pr.nounced a signif.cant incr.ase in Im.gr.up com.ar.ng to contr.l. Also, αf. （plasm. alpha f.topr.tein）, CEA （car.inoem.r.onic antigen）, CK （cr.atine kinase）, CK-m. （cr.atine phosphokinase m.ocar.ial band） and LDH （lactate dehydr.genase） clar.f. a signif.cant incr.ase in Im.gr.up com.ar.ng to contr.l. Both β-car.tene and hesper.din m.tigate the deleter.ous ef.ects of.Im.on pr.vious par.m.ter.. β-Car.tene and hesper.din m.y pr.tect hem.topoietic system.and hear. m.scle against toxicity of.Im. These im.r.vem.nts of.the r.sults clar.f. the pr.tective ef.ect of.the used antioxidants.
