Correlation of DNA ploidy to tumor histologic grade, clinical variables, and survival in dogs with mast cell tumors.     

R D Ayl  C G Couto  A S Hammer  S Weisbrode  J G Ericson  L Mathes 《Veterinary pathology》1992,29(5):386-390

By using flow cytometry, a retrospective analysis of the DNA content of 40 primary canine mast cell tumors and seven lymph nodes that contained metastatic mast cell tumor from 44 dogs of various breed, sex, and age was performed on formalin-fixed, paraffin-embedded samples of the tumors and nodes. These samples were chosen according to the following criteria: samples contained sufficient well-preserved tumor tissue in the paraffin block for processing, sufficient patient history data were available, clean and homogeneous cell suspensions were obtained after processing, and interpretable DNA histograms were produced on analysis. The ploidy data obtained were compared with the histopathologic grade, the anatomical site of occurrence, the clinical stage of the tumors, and the survival of the dogs. Over 70% (29/40) of the mast cell tumors were diploid. Three metastatic mast cell tumors in lymph nodes had the same ploidy status as their corresponding primary tumors. In five dogs, mast cell tumors from multiple sites in each dog displayed similar ploidy status. Of 26 dogs evaluated for survival times, 69% (18/26) had diploid tumors and 31% (8/26) had aneuploid tumors. When numbers of diploid versus aneuploid tumors were compared, no significant difference was found between any two grades, clinical stages, or anatomic sites. A significant difference (P = 0.02) was found, however, between aneuploid and diploid tumors when comparing Stage I and non-Stage I disease. The Kaplan-Meier survival plot indicated a tendency towards an increased survival within the first year in dogs with diploid versus aneuploid tumors (P = 0.06).  相似文献

Flow Cytometry Identification of X- and Y-Chromosome-Bearing Goat Spermatozoa   总被引：3，自引：0，他引：3  

I Parrilla  JM Vazquez  J Roca  EA Martinez 《Reproduction in domestic animals》2004,39(1):58-60

Flow cytometric sorting technology was used to measure the difference in DNA content between X- and Y-chromosome-bearing spermatozoa in bucks. Spermatozoa were analysed by flow cytometry to characterize X- and Y-chromosome-bearing sperm populations and to quantify the DNA difference between them. Two symmetrical, overlapping and clearly separated peaks, corresponding to X- and Y-bearing spermatozoa, were detected. The difference in fluorescence intensity between the peaks was 4.4 +/- 0.03% without any significant inter- or intra-animal variations. Therefore, the identification and selection of high-purity samples of sperm populations for sex sorting is easier in bucks compared with other domestic species.  相似文献

Effect of bovine seminal plasma on bovine endometrial epithelial cells in culture          下载免费PDF全文

T Nongbua  Y Guo  A Edman  P Humblot  JM Morrell 《Reproduction in domestic animals》2018,53(1):85-92

The purpose of this study was to investigate the effect of seminal plasma (SP) from bulls of known fertility on bovine endometrial epithelial cells (bEEC) in culture. The bEEC from passage 5, approximately 5.0–13 × 10⁵ cells per flask, were challenged with SP from bulls of high or low fertility (n = 3 and 2, respectively) or PBS (control), at 1% (75 μl) or 4% (300 μl) and were incubated for 72 hr (n = 13 per challenge). Total cell number and viability of bEEC after challenge with 1% SP from either high‐ or low‐fertility bulls (75H or 75L, respectively) did not differ from controls. In contrast, challenge with 4% of SP from high‐ or low‐fertility bulls (300H or 300L) negatively affected bEEC cell number and viability. Challenge with 300 L had a greater adverse effect than 300H. These results suggest that the negative effect of bovine SP on bEEC is both dose‐dependent and fertility‐dependent.  相似文献   

A framework for evaluation of on-farm mastitis diagnostics in Australia     

RN Zadoks  E Scholz  SM Rowe  JM Norris  HB Pooley  J House 《Australian veterinary journal》2023,101(4):142-152

Numerous culture-based diagnostics are available on the Australian and international markets for on-farm detection of bacterial pathogens in milk. Use of such diagnostics may provide an opportunity to improve the prudent use of antimicrobials in udder health management. Farms are low-resource settings in terms of diagnostic microbiology capacity. The World Health Organisation has identified criteria for the evaluation of diagnostic tests in low resource settings based on Accuracy, Sensitivity, Specificity, User-friendliness, being Rapid or Robust, Equipment-free and being Deliverable (ASSURED). Here, we review how those criteria can be interpreted in the context of microbiological diagnosis of mastitis pathogens, and how on-farm diagnostics that are currently available in Australia perform relative to ASSURED criteria. This evaluation identifies multiple trade-offs, both with regard to scientific criteria and with regards to convenience criteria. More importantly, the purpose of testing may differ between farms, and test performance should be evaluated relative to its intended use. The ability of on-farm mastitis diagnostics to inform mastitis treatment decision-making in a timely and cost-effective manner depends not just on test characteristics but also on farm-specific pathogen prevalence, and on the farm enterprise's priorities and the farm manager's potential courses of action. With most assay evaluations to date conducted in professional laboratories, there is a surprising dearth of information on how well any of the diagnostic tests perform on-farm and, indeed, of the on-farm decision-making processes that they aim to inform.  相似文献   

Salivary gland neoplasia in the dog and cat: survival times and prognostic factors     

Hammer A  Getzy D  Ogilvie G  Upton M  Klausner J  Kisseberth WC 《Journal of the American Animal Hospital Association》2001,37(5):478-482

Twenty-four dogs and 30 cats with histopathologically confirmed salivary gland neoplasia were retrospectively reviewed in a multi-institutional study. The predominant presenting complaint for animals with salivary gland neoplasia was that of a mass being noted by the owner; other common complaints included halitosis, dysphagia, and exophthalmia. Siamese cats were overrepresented, indicating a possible breed predisposition. The most common histopathological type was simple adenocarcinoma. Cats had more advanced disease at diagnosis than did dogs, and clinical staging was prognostic in dogs. The median survival times for dogs and cats were 550 days and 516 days, respectively.  相似文献   

Die Variabilität einiger Komponenten der Allogamieneigung bei der Kulturgerste (Hordeum vulgare L. s. l.)     

Karl Hammer 《Genetic Resources and Crop Evolution》1975,23(1):167-180

Zusammenfassung Zur Einschätzung der Allogamieneigung der Gerste wurde die Variabilität der für die Anemophilie bedeutenden Merkmale Stigmatagröße, Antherenlänge und Antherenejektion geprüft. In Voruntersuchungen an 5000 Sommer- und 1000 Wintergersten konnten 155 Sippen gefunden werden, die zur Chasmogamie neigen. Bei der autogamen Kulturgerste sind die Anemophiliemerkmale gegenüber den allogamenHordeum-Species meist deutlich reduziert. Das betrifft besonders die Antherenlänge und die Antherenejektion, während die Stigmatagröße, die auch bei Autogamen den Ansatz und damit die Anzahl der Nachkommen beeinflußt, relativ wenig vermindert ist. In allen Merkmalen wurde eine große Variabilität der Komponenten der Anemophilie gefunden, auch bei der im allgemeinen strenger autogamen Sommergerste.

Some aspects of the tendency to allogamy and their variability in barley (Hordeum vulgare L. s. l.)

Summary The variability of stigma size, anther length, and anther extrusion as important characters of anemophily was examined in barley to estimate its tendency to allogamy. 5000 spring and 1000 winter barleys were examined, 155 of which exhibited a tendency to chasmogamy. The characters of anemophily are reduced for the most part of autogamous cultivated barleys compared with allogamousHordeum species, especially as to anther length (table 4) and anther extrusion (table 5). There is a relatively little reduction of stigma size (table 3), because this character influences the seed set and with this the number of offspring in autogamous species too. A comparatively high variability could be found for all characters of anemophily even in spring barley, which is in general stronger autogamous than winter barley.
