Cytology of the cerebrospinal fluid in dogs with brain tumors and spinal cord compression. Part 4]     

V Grevel  B Machus  C Steeb 《Tier?rztliche Praxis》1992,20(4):419-428

The results of cerebrospinal fluid (CSF) cytology of 9 dogs with brain tumors and 50 dogs with spinal cord compression are discussed. Of the 50 dogs with spinal cord compression, disc protrusion was diagnosed in 31, myelomalacia in 7, discospondylitis in 3 and spinal cord tumors in 9 dogs. In 4 of 9 dogs with brain tumors, tumor cells could be found by the sedimentation apparatus of K?lmel. Pleocytosis existed in 6 patients. In about 70% (29 of 41) of cases with disc protrusion, more than 200 cells could be evaluated in the CSF sediment, consisting mostly of transformed lymphocytes and activated monocytes. As the neurologic deficits increased, the amount of cells and especially cell complexes increased. This was especially evident in cases with myelomalacia of the spinal cord. Only in cases with discospondylitis or spinal cord neoplasia was the CSF cytology unchanged.  相似文献

Verification by polymerase chain reaction of vertical transmission of Theileria sergenti in cows   总被引：2，自引：0，他引：2       下载免费PDF全文

To evaluate the transplacental transfer of Theileria sergenti infection in cattle, we used DNA probes to detect T. sergenti in 6 pregnant cows and their calves. All the animals were monitored by parasitologic, serologic, and polymerase chain reaction (PCR) assays for a predicted 875-base-pair (bp) DNA product and a 684-bp amplicon detected by nested PCR in the blood and spleens of aborted fetuses. An open reading frame (ORF) starting at nucleotide 170 and terminating at position 1021 was shown to code for a polypeptide of 283 amino acid residues. All 6 dams and 5 calves were positive for T. sergenti in all tests. One calf was positive only with nested PCR. We conclude that transplacental transmission of T. sergenti is a significant problem. The relevance of the data in the programmed introduction of new (especially pregnant) animals into established clean herds needs serious consideration with regard to control of theileriosis and other tickborne diseases.  相似文献   

Leishmaniasis phytotherapy. Nature's leadership against an ancient disease.     

P B de Carvalho  E I Ferreira 《Fitoterapia》2001,72(6):599-618

The use of phytotherapy to treat human diseases has its roots in pre-historical times. Despite the modern advances achieved in the field of synthetic chemistry, the most efficient drugs available have their genesis directly or indirectly related with the vegetal kingdom. Indigenous communities have long used plant extracts to treat illnesses. Many of these extracts have shown effective action, with new bioactive compounds being extracted and screened every year. These extracts have also proven to be good sources of therapeutic agents to the treatment of Leishmaniasis. This work highlights some of these agents, while trying to emphasize the importance of plants as a source of new and powerful drugs against this widespread disease.  相似文献

Evaluation of Corn Gluten Feed as a Dietary Ingredient for Pond-Raised Channel Catfish Ictalurus punctatus     

Edwin H.  Robinson  Menghe H.  Li  Bruce B.  Manning 《Journal of the World Aquaculture Society》2001,32(1):68-71

Abstract.— This study was conducted to evaluate corn gluten feed as an alternative feedstuff in the diet of pond-raised channel catfish Ictalurus punctatus . Three 32%-protein diets containing 0%, 25%, or 50% corn gluten feed were tested. Channel catfish fingerlings (average weight: 57 g/fish) were stocked into 15 0.04-ha ponds at a rate of 18,530 fish/ha. Five ponds were used for each dietary treatment. Fish were fed to satiation once daily for a 147-d growing period. No differences were observed in feed consumption, weight gain, feed conversion ratio, survival, or fillet protein concentration among fish fed the test diets. Fish fed diets containing 25% and 50% corn gluten feed exhibited a lower level of visceral fat and a higher carcass yield than fish fed the control diet without corn gluten feed. The diet containing 50% corn gluten feed resulted in a lower level of fillet fat and a higher level of moisture than the control diet. There were no visible differences in the coloration of skin or fillet of channel catfish fed diets with and without corn gluten feed. Results from this study indicated that channel catfish can efficiently utilize corn gluten feed at levels up to 50%n without adverse effect on feed palatability, weight gain, or feed efficiency. Corn gluten feed may be beneficial in reducing fattiness of channel catfish and improving carcass yield by reducing the digestible energy to protein ratio of the diet.  相似文献   

Flow cytometric analysis of intracellular complexity and CD45 expression for use in rapid differentiation of leukocytes in bovine blood samples.     

L S Pelan-Mattocks  B A Pesch  M E Kehrli 《American journal of veterinary research》2001,62(11):1740-1744

OBJECTIVE: To develop an efficient and reliable method that accurately differentiates bovine lymphocytes from monocytes in leukograms. SAMPLE POPULATION: Blood samples from 30 healthy cows and 1 calf with bovine leukocyte adhesion deficiency. PROCEDURE: Flow cytometric analysis of intracellular complexity and CD45 expression on bovine leukocytes was compared with results for conventional light microscopy methods. Verification of leukocyte subpopulations determined by intracellular complexity and CD45 expression was conducted, using 2-color phenotypic analysis with selected monoclonal antibodies. RESULTS: The CD45 and side-scatter properties of bovine leukocytes clearly differentiated cell types, including neutrophils, eosinophils, monocytes, and lymphocytes. CONCLUSIONS AND CLINICAL RELEVANCE: This is a rapid assay that is simple to use. More importantly, it is more accurate than the conventional method that involves the use of blood slides and light microscopy, because of the ability of the assay to readily distinguish bovine monocytes and lymphocytes. Rapid preparation of samples and short analysis times allow for efficient and reliable examination of a large number of samples, and the task of viewing slides by light microscopy is eliminated. The labor-savings benefit of this procedure is most apparent in research environments that require frequent processing of batches of blood samples.  相似文献   

Histopathological and hematological findings in myeloid leukemia induced by a new feline leukemia virus isolate   总被引：2，自引：0，他引：2  

S R Toth  D E Onions  O Jarrett 《Veterinary pathology》1986,23(4):462-470

Myeloid leukemia was induced by a new feline leukemia virus isolate FeLV-AB/GM-1 in a high proportion of cats. The latency period was short. Three to 5 weeks after infection early changes were detectable in the bone marrow, and cats developed leukemia 5 to 8 weeks after infection. The results of the present histological and cytological studies suggested that there were two stages in the development of leukemia. The first stage appeared to be equivalent to the syndrome of bone marrow dysplasia or preleukemia which, however, converted rapidly to leukemia. Cytopenia(s) were the main hematological findings in all preleukemic and leukemic cats. White blood cell counts were low or normal, but the number of leukemic and abnormal cells increased in the peripheral blood with the progression of the disease. This reliable model system lends itself to further studies to elucidate the pathogenesis of myeloproliferative disorders.  相似文献   

Quantitation of natural antibodies to infectious bursal disease in Nigerian indigenous chickens     

E O Sokale  A Oyejide 《Comparative immunology, microbiology and infectious diseases》1986,9(1):53-57

Serum samples collected from 687 indigenous chickens located in small scattered groups in four states of Nigeria were examined for antibodies to infectious bursal disease (IBD) virus by the agar-gel precipitation (AGPT) and counterimmunoelectrophoresis (CIEOP) tests. 51 of the positive samples were further titrated by each of the two techniques. CIEOP detected more positive reactors (74.59%) than AGPT (58.95%). CIEOP also detected higher antibody levels among the reactors [geometric mean titre (GMT) of 51 samples was 23.02] when compared to AGPT. GMT of the same 51 samples was 21.8. The prevalence of antibodies to IBD virus in the indigenous chickens ranged from 64.7 to 77.7% CIEOP reactors between states. Since reports of IBD outbreaks among these chickens are rare unlike the situation among commercial poultry flocks, it was concluded that local chickens probably act as carriers of IBD virus.  相似文献   

Periodontal disease. Therapy and prevention     

B J Hawkins 《Veterinary Clinics of North America: Small Animal Practice》1986,16(5):835-849

Success in veterinary dentistry lies in good home care and regular, thorough dental prophylaxis. The removal of supragingival and subgingival calculus must be accomplished before periodontal disease can be controlled. When gingival sulcus depths exceed 4 or 5 mm, the gingivae must be excised or reflected to allow proper treatment of the pocket area. Antibiotic therapy should be instituted in the extensively involved veterinary dental patient.  相似文献
