Pyrethroid esters a.e widely used a. insecticides worldwide. In this study, we a.med to eva.ua.e the ha.mful effect of delta.ethrin on the ma.e reproductive system through the a.sessment of reproductive hormones, infla.ma.oryma.kers, a.d testicula. function. To a.hieve our a.m, eighty ma.e 7-9-week-old, Wista. ra.s were ta.en, weighed, a.d divided into four experimenta. groups. The first group wa. kept a. a.control group, a.d the other three groups were given delta.ethrin ora.ly a. different concentra.ions (0.87, 8.7, a.d 17.4 mg/kg body weight) for nine weeks.

a.socia.ion between Tropica. Convection a.d Borea. Wintertime Extra.ropica. Circula.ion in 1982/83 a.d 1988/89

Borea. wintertime extra.ropica. circula.ion is studied in rela.ion to the tropica. convection during the 1982/83 el Niño a.d 1988/89 La.Niña. The a.oma.y structure of 1982/83 a.d 1988/89 over the extra.ropics revea.s rema.ka.ly different fea.ures a. the longitudina. tropica. forcing region cha.ges. The Rossby wa.e source (Positive) shows the la.gest ma.imum over Ea.t a.ia.in both yea.s due to the persistent hea.ing from the western Pa.ific wa.m pool a.ea. However, the sink term shows contra.ting fea.ures over the subtropics a.d extra.ropics between the two yea.s. In the el Niño yea., enha.ced tropica. convection over the ea.tern Pa.ific produces the Rossby wa.e sink a. 10°N a.d shifted ea.twa.d over the North Pa.ific, while in the La.Niña.yea., the sink a.ea.is shifted westwa.d over the North Pa.ific. The contra.ting fea.ures between the two events in mea.-eddy intera.tion a.pea.s especia.ly over the downstrea. a.ea.of the Ea.t a.ia. Jet. The extension (retra.tion) of the mea.flow ea.twa.d (westwa.d) to the ea.t (west) of the da.eline is rela.ed with the effect of the westwa.d (ea.twa.d) E-vector a.d the strengthening (wea.ening) of the nega.ive a.oma.ies of the ba.otropic growth of kinetic energy. Hence, a.most opposite cha.a.teristics between the two events ca. expla.n the close rela.ionship of tropica. convection a.d the extra.ropica. interna. va.ia.ility.
