Aim: t.e funct.onal int.g.it. of t.e blood-t.st.s barrier (Bt.) in male mice exposed t. Cr(V) was st.died in order t. clarify t.e mechanism underlying.t.st.cular injury. Met.ods: Adult.male mice were subcut.neously inject.d repeat.d doses of 8.02 mmol (0.5 mL) of Cr/*** for 5 days. Animals receiving.a similar volume of bis(hydroxyet.yl)-aminot.is(hydroxymet.yl)met.ane buffer (Bt. were used as cont.ols. t.e animals were sacrificed on day 6 and small frag.ent. of seminiferous t.bules, approximat.ly 8-10 mm leng.h, were incised and sut.red at.bot. ends. t.ey were exposed in vit.o t. horseradish peroxidase-cont.ining.cult.re medium for 10 minut.s. t.ssues were t.en fixed and processed for ult.ast.uct.ral st.dies. Result.: Cont.ols and Cr(V)-t.eat.d g.oup result.d in t.e upt.ke of t.e t.acer by Sert.li cells. However, t.e major finding.consist.d in t.e permeabilit. of t.e Bt. only in t.e Cr(V)-g.oup, as evidenced by t.e presence of t.e t.acer wit.in t.e junct.ons bet.een t.e neig.bouring.Sert.li cells. Conclusion: t.e Bt. is disrupt.d in mice submit.ed t. Cr(V). t.e permeabilit. of t.e Bt. is a crucial feat.re t. be invest.g.t.d for t.e underst.nding.of lesions wit.in t.e seminiferous t.bule.

Opt.cal fiber opt.odes are at.ract.ve sensing.devices due t. t.eir abilit. t. perform point.measurement.in remot. locat.ons.

A linearly t.pered opt.cal fiber t.p is covered by a double overlay： t.e inner one - a silver t.in film and over it.- a dielect.ic layer, wit. t.is combinat.on allowing.t. achieve, at.a specific waveleng.h rang., surface plasmonic resonance （SPR） int.ract.on sensit.ve t.pically, t.e int.rrog.t.on of t.e SPR sensing.t. t.e refract.ve index of t.e surrounding.medium. st.uct.res is performed, considering.spect.oscopic t.chniques, but.in principle, a far bet.er performance can be obt.ined, considering.t.e reading.of t.e phase of t.e lig.t.at.a specific waveleng.h locat.d wit.in t.e spect.al plasmonic resonance. t.is is t.e approach which is st.died here in t.e cont.xt.of t.e proposed opt.cal fiber opt.ode config.rat.on. t.e analysis performed shows t.e combinat.on of a silver inner layer wit. a dielect.ic t.t.nium oxide layer wit. t.ned t.icknesses enables sensit.ve phase reading.and allows t.e operat.on of t.e fiber opt.c opt.ode sensor in t.e t.ird t.lecommunicat.on waveleng.h window.
