Clinical response of nasal adenocarcinoma to cisplatin chemotherapy in 11 dogs.     

K A Hahn  D W Knapp  R C Richardson  C L Matlock 《Journal of the American Veterinary Medical Association》1992,200(3):355-357

In 11 dogs with nasal adenocarcinoma, IV treatment with 2 to 8 cycles of cisplatin at a dosage of 60 mg/m2 of body surface, given at 3-week intervals, resulted in a survival time of 8 to 128 weeks (mean, 32.7 weeks; median, 20 weeks). Radiography revealed complete remission in 2 dogs and partial remission in 1 dog, for an overall response rate of 27%. Clinical problems such as nasal discharge (n = 11), sneezing (n = 6), and epistaxis (n = 4) resolved in 1 to 2 weeks in all dogs after beginning chemotherapy.  相似文献   

Effect of a supply of raw or extruded rapeseeds on digestion in dairy cows.     

A Ferlay  F Legay  D Bauchart  C Poncet  M Doreau 《Journal of animal science》1992,70(3):915-923

The influence of extruded oilseeds on total tract digestibility and ruminal digestion in dairy cows was studied in three cows fed a hay-concentrate (60.5/39.5; 3.7% fatty acids in diet on DM basis) control diet (C) or the same diet supplemented with raw (R) or extruded (ER) rapeseeds (8.0% fatty acids in diet DM). The experimental design was a 3 x 3 Latin square design. Compared with diet C, diets containing rapeseed decreased ruminal OM digestibility (9.5%, P less than .10) and increased (P less than .05) the proportion of propionate in ruminal fluid VFA. Extrusion had no effect on DM and OM total tract digestibilities and increased (P less than .10) N digestion. Microbial N flow at the duodenum was calculated taking into account solid-adherent bacteria (SAB) and liquid-associated bacteria (LAB). Duodenal flows of total, SAB, and LAB of OM and N did not change with diet. Extrusion of the rapeseeds did not modify (P less than .10) the proportion of bacterial N at the duodenum and had no effect on crude fiber digestibility. This trial demonstrates that rapeseeds in hay-based diets can be fed at levels of up to 14% of the diet without adversely affecting crude fiber digestibility.  相似文献   

Consistency of results from the Vettest 8008 clinical biochemistry analyser.     

C J Little  G Gettinby  J Downs  C B Marshall 《The Veterinary record》1992,130(19):419-424

Findings are presented on the precision of a clinical biochemistry analyser designed specifically for veterinary use. Twenty biochemical analytes have been examined in detail for variation within and between runs. The results indicate that the analyser can provide high precision for all the analytes with the possible exception of calcium, and suggest that the instrument can be used with confidence in the practice laboratory to aid diagnosis and to monitor biochemical changes in animals receiving treatment.  相似文献   

Comparative virulence of Haemophilus parasuis serovars 1 to 7 in guinea pigs.     

V J Rapp-Gabrielson  D A Gabrielson  G J Schamber 《American journal of veterinary research》1992,53(6):987-994

Reference strains for Haemophilus parasuis serovars 1 to 7 were examined for virulence by inoculation of guinea pigs. Guinea pig response to intraperitoneal inoculation was similar for the 7 reference strains. However, apparent differences in virulence were detected after intratracheal inoculation. Cells of the references strains for serovars 1 and 5 were most invasive, causing moribundity or death at higher doses and a persistent septicemia at lower doses. Haemophilus parasuis could be isolated from respiratory and systemic sites; purulent bronchopneumonia, pericarditis, and pleuritis were apparent in infected guinea pigs. Inoculation of cells of the reference strains for serovars 2 and 6 also resulted in bronchopneumonia and moribundity or death in some guinea pigs; however, reisolation of H parasuis and microscopic lesions at necropsy were less pronounced than those observed with serovars 1 and 5. Inoculation of cells of serovars 3, 4 and 7 induced only transient clinical signs and minimal evidence of H parasuis infection at necropsy. The data from intratracheal inoculation of guinea pigs are similar to data from other investigations in swine, indicating differences in the pathogenic potential of H parasuis strains. Thus, guinea pigs may be useful as a laboratory animal model for examining cellular factors associated with virulence and immunogenicity of H parasuis.  相似文献   

Ultrastructural observations on autolytic changes of atrial specific granules in pig heart.     

M Castagnaro  A Benatti  F Guarda 《Research in veterinary science》1992,52(1):120-122

The progressive autolytic changes of atrial specific granules (ASGS) up to 24 hours after death were studied electron microscopically. Tissue samples taken from the left auricular myocardium of four pig hearts at 0, 0.5, 1.5, 3.5, 6, 12 and 24 hours post mortem were fixed for 24 hours by immersion in 2.5 per cent cacodylate buffered glutaraldehyde (pH 7.4). Two pig hearts were kept at 20 degrees C and two at 4 degrees C. Although typical autolytic changes were seen in many organelles, no remarkable modifications in aspect, distribution, content and diameter of ASGS were observed in all samples. The results of this study indicate that ASGS are not morphologically affected by the autolytic processes, at least during the first 24 hours. Hence, the electron microscopic evaluation of ASGS does not need a particular fixation method such as perfusion. This may eliminate technical problems when slaughterhouse material is used.  相似文献   

Bovine spongiform encephalopathy: epidemiological features 1985 to 1990.   总被引：4，自引：0，他引：4  

J W Wilesmith  J B Ryan  W D Hueston  L J Hoinville 《The Veterinary record》1992,130(5):90-94

Following the identification of bovine spongiform encephalopathy (BSE) in the British cattle population in 1986 epidemiological studies were launched. This paper provides an updated account of the epidemiological features of BSE from 1985, when the first cases, based on clinical histories, occurred, until 1990. The number of cases up to December 1989 represents an annual incidence of 3.9 confirmed cases per 1000 adult animals in Great Britain. Many more dairy herds were affected than beef suckler herds, a difference attributable to the difference in feeding practices between the two herd types. The geographical variation in incidence previously described has persisted with the highest incidence in the south and east of England. Other features of the epidemiology, including the low within-herd incidence, remained unaltered from the earlier findings. The results support the previously suggested hypothesis that the outbreak of BSE was due to the sudden exposure of the cattle population to a scrapie-like agent in 1981/82. There was no evidence of direct transmission between cattle during the period considered.  相似文献   

Effect of the manganese content in laying hen feed with different Ca and mineral levels on the egg shell quality and bone mineralization of hens]     

C Ochrimenko  A Lemser  G Richter  U Krause  H Bonsak 《Archives of Animal Nutrition》1992,42(1):25-35

Four experiments with 270, 44, 432 and 66800 Leghorn hens were carried out to investigate the influence of various Mn additions to diets differed in mineral or Ca contents on egg shell quality. The addition of 300 mg Mn/kg diet improved significantly egg shell breaking strength by 4 N over one year. The supply of 50-500 mg Mn/kg diet for 10-24 weeks of the second half of laying year did not influence the egg shell quality. Addition of mineral mixture or Ca grit to layer rations with adequate or higher Mn levels did not influence egg shell strength. High mineral content in a low manganese diet increased number of cracks by 3%. Strength, weight and ash content of tibia were significantly reduced by feeding a low mineral level. Addition of 50-150 mg Mn per kg low mineral diet normalized partially tibia stability in young hens. It was concluded that supplied dietary Manganese influences calcification positively only in young hens. High levels of Ca did not influence the effects of Mn. 50 mg Mn per kg layers mixture have been considered as an essential supply.  相似文献   

Comparison of a vaccine strain and field isolates of avian reovirus by T1-oligonucleotide mapping.     

M R Rekik  A Silim 《Avian diseases》1992,36(2):237-246

Total RNA of eight avian reovirus isolates and the S1133 strain were compared by RNase T1-oligonucleotide mapping. The viruses were propagated in Vero cell cultures, and viral genomes were extracted from purified virions for comparison. Pairwise comparisons of the oligonucleotide maps showed genetic variation among reovirus isolates ranging from 78% to 99%. The T1 fingerprints of the RNA of isolates 1103, 724, 615, and 684 differed slightly from the standard S1133 strain, suggesting that the vaccine strain might have changed and became part of the circulating reoviruses. In contrast, when compared with the vaccine strain, isolates 902, 644, and 6207 showed greater differences in the fingerprint pattern. This genomic diversity may be due to the differences in immunological status of the affected avian population and/or due to simultaneous coinfection with different reovirus strains.  相似文献
