A 4-year-old male Pekingese dog was admitted to the veterinary medical center, Chonbuk National University for evaluation of severe hind limbs ataxia, atrophy and paresis. Diagnosis based on physical examination, neurological assessment and computed tomogram (CT) indicated multiple thoracolumbar intervertebral disc disease (IVDD) throughout the thoracic and cranial lumbar spine. Traditional veterinary medicine (TVM) based diagnosis was kidney yang deficiency syndrome. Initial high dose prednisolone therapy (1.5 mg/kg PO, twice daily) did not show any significant improvement. The dog was then treated with electroacupuncture (EA) and oriental herbal medicine for 6 months, which significantly improved mobility, proprioception and spinal posture of the patient.

This report describes the importance of careful diagnosis of intrapelvic urethra in cases of pelvic fractures. A 2-year-old intacted female Spitz with multiple pelvic fractures following traffic accident was treated with internal fixation. Urethral catheter was dislodged and patient discharged in good conditions. Next day, the patient was readmitted with vomiting and dysuria. Retrograde urethrography (RUG) revealed a urethral rupture by a broken bone fragment at bladder outlet which repaired by urethral anastomosis. A delayed diagnosis of urethral rupture was because of absence of the signs at the time of first visit. Moreover early urethral catheterization can mask the problems of urinary tract. As urethral rupture in female dog has been reported uncommon compared with male, examination including RUG should more careful.

Wild species in the Triticeae tribe are very valuable resources for agronomic improvement in cereal crop species. Intergeneric hybrids were produced between several barley cultivars and perennial species in the genera Elymus, Thinopyrum, and Pseudoroegneria. Caryopsis formation and subsequent plantlet regeneration from embryo culture were variable depending on the hybrid combinations. Chromosome numbers and hybrid identity were confirmed by GISH analysis on the somatic cells of the hybrids. While the hybrids showed very robust vegetative growth and exceeded the parental spikes in size, their floral morphologies resembled that of the wild species. Meiotic chromosome analysis revealed that the bivalent formation frequency per cell ranged from 0.06 in Hordeum vulgare 'Betzes' x Elymus curvatus to 3.0 in Elymus humidus x H. vulgare 'Manley'. By GISH analysis on the meiocytes of the hybrid E. humidus x 'Manley', the frequency of autosyndetic bivalents exceeded the allosyndetic bivalent formation, which gave an insight into the genome constitution of E. humidus as an autoallohexploid species. Regardless of the low allosyndetic chromosome pairing between barley and E. humidus, this combination may be useful for further input, since E. humidus is known to carry many valuable genes for biotic and abiotic stress tolerance.

Les especes sauvages au sein de la tribu des bordees constituent une ressource trEs precieuse pour l'amelioration des caracteres agronomiques chez les cereales cultivees. Des hybrides intergeneriques ont ete produits entre plusieurs cultivars d'orge et des especes perennes au sein des genres Elymus, Thinopyrum et Pseudoroegneria. La formation de caryopses et la regeneration subsequente de plantules par sauvetage d'embryons se sont averees variables selon les hybrides. Le nombre de chromosomes ainsi que l'identite des hybrides ont ete confirmes par analyse GISH sur les cellules somatiques des hybrides. Alors que les hybrides montraient une croissance vegetative trEs vigoureuse et excedaient les parents en ce qui a trait a la taille des epis, leur morphologie florale ressemblait a celle des espEces sauvages. L'analyse des chromosomes meiotiques a revele que la frequence de bivalents variait entre 0,06 par cellule chez l'hybride H. vulgare 'Betzes' x E. curvatus et 3,0 par cellule chez l'hybride E. humidus x H. vulgare 'Manley'. En analyse GISH sur les meiocytes de l'hybride E. humidus x H. vulgare 'Manley', la frequence de bivalents autosyndetiques excedait celle des bivalents allosyndetiques, ce qui porte a croire que la constitution genomique de PE. humidus correspond a celle d'un autoallohexaploide. Sans egard a la faible frequence d'appariement chromosomique allosyndetique entre l'orge et l'E. humidus, cette combinaison pourrait s'averer propice a de futurs efforts puisqu'il est rapporte que PE. humidus porte plusieurs gEnes utiles pour la resistance aux stress biotiques et abiotiques.
