Equine laryngeal hemiplegia. Part V. Central nervous system pathology     

Cahill JI  Goulden BE 《New Zealand veterinary journal》1986,34(11):191-193

Evidence of long central nerve fibre degeneration (axonal spheroids) in the lateral cuneate nuclei was found in all eight Thoroughbreds affected clinically and subclinically with equine laryngeal hemiplegia, but in only one of six control animals. It was considered that these spheroids may signify a central nervous component of the disease process of laryngeal hemiplegia although until further investigations are performed no firm conclusions regarding the relationship of these findings with laryngeal hemiplegia could be made. Examination of the left and right nucleus ambiguus of clinical and subclinical laryngeal hemiplegic horses revealed no pathological alterations.  相似文献

Oral surgery. Radical resection of maxillary and mandibular lesions     

C E Harvey 《Veterinary Clinics of North America: Small Animal Practice》1986,16(5):983-993

The results obtained following both maxillectomy and mandibulectomy in animals with benign disease show that these procedures are practical. The challenge is to select those animals with malignant disease where the disease is sufficiently localized so that radical resection will be curative, or where residual disease can be controlled by adjuvant therapy. The series of cases reported in Tables 1 and 2 represent animals treated during the "developmental phase" of these procedures. With 5 years of case experience now available, the usefulness and limitations of these procedures are becoming clearer.  相似文献

A defect in thyroglobulin synthesis in an inherited ovine goitre: possible neonatal respiratory distress syndrome     

Jones BR  Greenway RM  Jolly RD  Labuc RH  Davis GB 《New Zealand veterinary journal》1986,34(9):145-148

A ram lamb with congenital goitre showed signs of respiratory distress at birth. All previously affected lambs from this flock bad been born dead or bad died soon after birth. The serum free-thyroxine level at 1 birth was low (9.8 pmol/l) but treatment with oral L-thyroxine resulted in an increase in thyroxine blood levels to above normal and regression of the goitre. Four weeks after withdrawal of thyroid supplementation and when the lamb was eight weeks old, the radio iodide uptake mechanism of the thyroid glands was shown to be intact but the iodide was not organified. Low normal peroxidase activity was demonstrated in fresh thyroid tissue but gel electrophoresis demonstrated an absence of normal thyroglobulin from extracts of the goitrous thyroid. This lamb and the other affected lambs of this flock have an inherited defect in thyroglobulin synthesis and it is likely that the respiratory distress was associated with the low levels of thyroid hormone affecting foetal lung development.  相似文献

Dual infections of red deer (Cervus elaphus) by Leptospira interrogans serovars copenhageni and hardjo     

Flint SH  Marshall RB  Winter PJ 《New Zealand veterinary journal》1986,34(5):70-71

On a property in the Nelson District, blood and urine samples were taken from red deer (Cervus elaphus) from which low (<1:100) antibody titres to serovar copenhageni and suspected leptospiral abortions had previously been reported. A total of 27 hinds were sampled. Microscopic agglutination test (MAT) titres in sera ranging from 1:32 to 1:128 were found in six animals. Thirteen leptospiral isolations were made from nine of the 27 urine samples. Four of these were typed as copenhageni and nine as hardjo. Two cultures were prepared from each urine sample and hardjo and copenhageni were both isolated from single urine samples from two animals. None of the 27 deer had serum MAT titres at 1:32 or above to copenhageni.  相似文献
