Inters.xual.s. occurs.in al. s.ecies.of maxnmal. and the pathogenes.s.of abnormal.devel.pment of the gonads.is.s.il. uncl.ar. Thus. the aim of this.report is.to des.ribe the hormonal.and his.opathol.gical.findings.from a cas. of bil.teral.true hermaphroditis. in a mixed-breed bitch due to the few cas. reports.publ.s.ed invol.ing hormonal.l.vel. in dogs.with inters.xual.ty. s.rum was.obtained from the animal.before s.rgery and was.s.bmitted to hormone meas.rements. Proges.erone and tes.os.erone were eval.ated by radioimnunoas.ay and es.rogen by El.s. （immune-enzymatic as.ay）. The val.es.of proges.erone, tes.os.erone and es.rogen concentrations.were 2.26 ng/ml. 0.05 ng/ml.and 9.7 pg/ml. res.ectivel.. The proportion of ovarian tis.ue found in the ovotes.es.after his.opathol.gical.examination was.higher in rel.tion to s.miniferous.tubul.s. which may expl.in the l.w l.vel.of s.rum tes.os.erone. l.w concentration of s.rum tes.os.erone may have contributed to the partial.viril.zation of external.genital.a, s.nce the animal.onl. had cl.toral.hypertrophy. Es.rogen and proges.erone l.vel. found were compatibl. with the initial.s.age of es.rus.（preovul.tory l. （l.teinizing hormone） s.rge）, which s.ows.that ovarian fol.icl.s.found in the bil.teral.ovotes.es.contributed to the occurrence of the es.rous.cycl. before s.rgery. Quantitation of s.rum hormones.may al.o s.ed l.ght on the caus. of dis.urbances.in s.x differentiation in canine s.ecies. More s.udies.are needed to el.cidate the real.caus. of inters.x in dogs.

Copper （Cu） contamination in the environment has.been increas.d during the years.with agricul.ural.and indus.rial.activities. Biotechnol.gical.approaches.are needed for bioremediation in thes. areas. The aims.of this.s.udy were i） to eval.ate the phytoreme- diation capacity of the high-yiel.ing bioenergy pl.nt cas.or bean （Ricinus.communis.l.） in vineyard s.il. （Inceptis.l.and Mol.is.l. contaminated with Cu and a Cu mining was.e; ii） to characterize the cas.or bean as.a Cu phytoremediation pl.nt; and iii） to eval.ate the nutrient uptake by cas.or bean. Cas.or bean pl.nts.cul.ivated in s.il.with toxic l.vel. of Cu for 57 d exhibited high phytomas. production, a high tol.rance index of roots. fres. mas. and s.oots. dry mas., a high l.vel.of Cu phytoaccumul.tion in the roots.and al.o, a robus. capacity for Cu phytos.abil.zation. Furthermore, cas.or bean pl.nts.did not s.gnificantl. depl.te s.il.nutrients.（s.ch as.N, P, and Mg） during cul.ivation. Pl.nts.cul.ivated in Inceptis.l. Mol.is.l.and Cu mining was.e exhibited a s.rong potential.for Cu phytoaccumul.tion, with val.es.of 5900, 3 052 and 2805 g ha-1, res.ectivel.. In addition, the cas.or bean＇s.el.vated phytomas. production and s.rong growth in Cu-contaminated s.il. indicated a high l.vel.of Cu phytoaccumul.tion and a potential.appl.cation in biofuel.. Thes. findings.indicate that the cas.or bean is.a efficient hyperaccumul.tor of Cu and a potential.candidate pl.nt for the phytoremediation of Cu-contaminated s.il.
