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.f.ndings.f.om a cas. of.bil.teral.true hermaphroditis. in a mixed-breed bitch due to the f.w cas. reports.publ.s.ed invol.ing hormonal.l.vel. in dogs.with inters.xual.ty. s.rum was.obtained f.om the animal.bef.re 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 f.und in the ovotes.es.af.er his.opathol.gical.examination was.higher in rel.tion to s.minif.rous.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. f.und were compatibl. with the initial.s.age of.es.rus.（preovul.tory l. （l.teinizing hormone） s.rge）, which s.ows.that ovarian f.l.icl.s.f.und in the bil.teral.ovotes.es.contributed to the occurrence of.the es.rous.cycl. bef.re s.rgery. Quantitation of.s.rum hormones.may al.o s.ed l.ght on the caus. of.dis.urbances.in s.x dif.erentiation in canine s.ecies. More s.udies.are needed to el.cidate the real.caus. of.inters.x in dogs.

Initial.oxidation behavior of.NiCoCrAl. coating prepared by arc-ion pl.ting has.been s.udied in air at 900, 1000 and 1100 ℃. The res.l.s.s.owed that phas. trans.1}rmation f.om trans.ent θ-Al.(2)O_(3) to α-Al.(2)O_(3) was.highl. rel.ted to the temperature and oxidation time.
