The effect of biological isolation and a molt-inducing regimen on the recovery of Mycoplasma gallisepticum from commercial Leghorn hens     

S L Branton  J D Simmons  J M Hardin 《Avian diseases》1989,33(3):574-577

Two trials were conducted to determine the effect of induced molt on the reisolation of Mycoplasma gallisepticum (MG) from commercial leghorn hens that had been eyedrop-inoculated with MG at 10 weeks of age. Chickens were maintained in a conventional floored chicken house on dry litter through 100 weeks of age. At age 64 weeks, 4 days (Trial 1), and at 100 weeks (Trial 2), hens were swabbed and cultured for MG and then molted in biological isolation units. Swabs were again taken at the end of each molt. No difference was observed in the number of MG isolations between molted hens and controls that did not undergo molting. However, a significant decrease in MG isolations was observed in both trials from swabs obtained when hens were housed on dry litter floors as compared with swabs taken from the same hens after 18 days (Trial 1) or 21 days (Trial 2) of confinement in isolation units.  相似文献

Subcutaneously implanted tissue chambers — a pharmacokinetic study     

C. R. CLARKE †  C. R. SHORT ¶  D. W. A. BOURNE‡ §  E. A. USENIK 《Journal of veterinary pharmacology and therapeutics》1989,12(3):312-321

The purpose of this study was to characterize the pharmacokinetics of a subcutaneously implanted tissue-chamber model. Thermoplastic tissue chambers were implanted in the paralumbar fossae of six steers. Starting 30 days after implantation, the distribution of intravenously administered antipyrine and phenylbutazone into the tissue chambers was studied. These pharmacokinetic experiments were repeated 10 days later to determine the effect of time after implantation on tissue-chamber distribution. Fifty days after implantation, tissue chambers were drained of transudate, refilled with sterile saline and the rate of influx of endogenous urea, creatinine and albumin was measured. Delayed diffusion of antipyrine and phenylbutazone into tissue chambers was well described using a compartmental model in which tissue-chamber fluid represented the third of three compartments arranged in series. The distribution of antipyrine into tissue chambers was greater than that of phenylbutazone; an observation which is well correlated with the high degree of protein binding of phenylbutazone. There was no effect of time on the penetration of the two agents. Rapid diffusion of urea and creatinine and extremely slow influx of albumin into chambers showed that these chambers formed true interstitial compartments.  相似文献   

Antagonism of medetomidine sedation by atipamezole in pigs.   总被引：1，自引：0，他引：1  

R Nishimura  H Kim  S Matsunaga  M Sakaguchi  N Sasaki  H Tamura  A Takeuchi 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》1992,54(6):1237-1240

The efficacy of atipamezole as a medetomidine antagonist was evaluated in pigs. The atipamezole doses (intramuscularly) were 80, 160, 320 and 480 micrograms/kg of body weight, which were one, two, four and six times higher than the preceding medetomidine dose (80 micrograms/kg, intramuscularly). Atipamezole effectively reversed medetomidine-induced sedation, and the optimal action was seen at doses of 160 and 320 micrograms/kg. Recovery from sedation was quick and smooth, and adverse effects such as hyperactivity or tachycardia were minimal with either dose.  相似文献   

Surgery of hepatic cysts in a cat.     

M Washizu  K Kobayashi  K Misaka  T Hayashi  G Kinoshita  M Kondo  S Aoki  H Orima  T Washizu 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》1992,54(5):1051-1053

A 2-year-old female Japanese domestic cat weighing 3.6 kg was presented due to marked abdominal distention and was diagnosed as hepatic cyst. The bile acid concentration of the hepatic cyst was as low as the serum bile acid concentration. The membrane of the cysts was excised from the edge of the compressed hepatic tissue and no other surgical manipulation was performed. This surgical procedure is simple and quick compared to hepatic lobectomy, however, it is necessary to evaluate the fluid of the cyst before performing this procedure.  相似文献   

A Quantitative Study of Ganglion Cells in the German Shepherd Dog Retina     

J. Gonzalez-Soriano  E. Rodriguez-Veiga  P. Martinez-Sainz  S. Mayayo-Vicente    P. Marin-Garcia 《Anatomia, histologia, embryologia》1995,24(1):61-65

As in the number of mammals, the most prominent feature of the ganglion-cell layer in the retina of the German shepherd dog is the sharp increase in the density of ganglion cells in the central area. There is an area of maximum density and also a ‘cat-like’ visual streak, located dorsal to the optic disc. The isodensity lines of ganglion-cell distribution is roughly concentric. Their values vary from 5300-13 000 cells/mm² in the central area, with the cells densely packed, to 1000 cells/mm² or less in the periphery, where the cells are sparsely distributed. There were some individual differences amongst the animals studied, although all of them were pure-bred dogs. This suggests that the configuration of the retina in the canine species is not only dependent on the breed itself but also on some other parameters such as phylogenetic heritage, environment, aptitude, lifestyle, or even training.  相似文献   

Suppurative Inflammation of Apocrine Sweat Glands (Suppurative Hidradenitis) in the Dog: A Retrospective Clinicopathological Analysis of 100 Cases     

DANNY W. SCOTT 《Veterinary dermatology》1995,6(2):75-78

Résumé— Une analyse rétrospective clinicopathologique a été menée chez 100 chiens présentant une hydradénite suppurative diagnostiquée par biopsie cutanée. Aucune prédisposition d'âge, de race ou de sexe n'a été mise en évidence. Tous les chiens présentaient cliniquement une folliculite bactérienne, ou une furonculose, ou les deux, qu'elle soit primaire ou secondaire à d'autres dermatoses. Aucene lésion clinique n'était pathognomonique d'hidradénite suppurative. Chez 73 chiens, l'hidradénite suppurative était associée microscopiquement à des degrés variables d'inflammation du follicule pileux. Chez 27 chiens, l'hidradénite suppurative était la seule évidence histologique d'inflammation annexielle. L'observation histopathologique d'hidradénite suppurative suggère l'existence sur le plan clinique d'une folliculite bactérienne, d'une furonculose, ou des 2. [Scott, D.W.

Resumen— Se llevó a cabo un estudio clinicopatológico retrospectivo en 100 perros con hidradenitis supurativa diagnosticada mediante biopsia cutánea. No se detectó predominancia alguna de raza, sexo o edad. A todes los perros se les habia diagnosticado clinicamente foliculitis o furunculosis bacteriana, o ambas, ya sea de forma primaria o secundaria a otras dermatosis. No se encontraron lesiones clinicas especificas indicativas de hidradenitis supurativa. En 73 animales, la hidradenitis supurativa estaba asociada con varios grados de inflamación folicular a nivel microscópico. En los 27 casos restantes, los anejos presentaban unicamente hidradenitis supurativa. La presencia de hidradenitis supurativa a nivel microscópico sugiere la existencia de foliculitis o furunculosis bacteriana clinicas, o de ambas. [Scott, D.W. Suppurative inflammation of apocrine sweat glands (suppurative hidradenitis) in the dog: a retrospective clinicopathological analysis of 100 cases (inflamación supurativa de las glándulas sudoriparas apocrinas (hidradenitis supurativa) en el perro: estudio clinicopatológico retrospectivo de 100 casos). Abstract— A retrospective clinicopathological study was conducted on 100 dogs with suppurative hidradenitis as determined by skin biopsy. No apparent age, breed, or sex predilections were recognized. All dogs had been given a clinical diagnosis of bacterial folliculitis, furunculosis, or both of these, whether primary or secondary to other dermatoses. There were no clinical lesions that uniquely suggested the presence of suppurative hidradenitis. In 73 dogs, suppurative hidradenitis occurred in conjunction with varying degrees of hair follicle inflammation microscopically. In 27 dogs, suppurative hidradenitis was the only histological evidence of adnexal inflammation. The histopathologic finding of suppurative hidradenitis suggests the existence of clinical bacterial folliculitis, furunculosis, or both of these.  相似文献
