Elemental composition of teeth with and without odontoclastic resorption lesions in cats     

Colley PA  Verstraete FJ  Kass PH  Schiffman P 《American journal of veterinary research》2002,63(4):546-550

OBJECTIVE: To determine elemental composition of teeth with and without odontoclastic resorption lesions (ORL) in cats. SAMPLE POPULATION: Normal teeth from 22 cadaver cats and ORLaffected teeth from 21 cats admitted to the veterinary hospital for dental treatment. PROCEDURE: An electron microprobe was used to analyze weight percentages of calcium, phosphorus, fluorine, sodium, magnesium, sulfur, potassium, and iron in enamel, dentin, and cementum. RESULTS: Calcium and phosphorus were the most abundant elements. Fluorine, sodium, and magnesium combined were < 5% and sulfur, potassium, and iron combined were < 0.1% of total elemental composition. In enamel of normal teeth, a significant sex-by-jaw location interaction was seen in mean (+/- SD) phosphorus content, which was higher in mandibular teeth of females (1764+/-0.41%) but lower in mandibular teeth of males (16.71+/-0.83%). Mean iron content in dentin of normal teeth was significantly lower in mandibular teeth than maxillary teeth (0.014+/-0.005% vs 0.023+/-0.019%). Mean enamel sodium content was significantly higher (0.77+/-0.046% vs 0.74+/-0.025) and mean enamel iron content was significantly lower (0.017+/-0.008% vs 0.021+/-0.005%) in ORLaffected teeth, compared with normal teeth. In cementum, mean fluorine content was significantly lower (2.98%+/-0.27 vs 2.99+/-0.20%) and mean magnesium content was significantly lower (0.54+/-0.13% vs 0.60+/-0.13%) in ORL affected teeth, compared with normal teeth. CONCLUSIONS AND CLINICAL RELEVANCE: Results of our study establish baseline mineral content of enamel, dentin, and cementum for normal teeth in cats. Minimal differences in mineral content of enamel and cementum of normal and ORL-affected teeth were detected.  相似文献   

Prevalence of odontoclastic resorption lesions and periapical radiographic lucencies in cats: 265 cases (1995-1998)     

Lommer MJ  Verstraete FJ 《Journal of the American Veterinary Medical Association》2000,217(12):1866-1869

OBJECTIVE: To determine whether odontoclastic resorption lesions were associated with radiographic evidence of periapical lucencies in cats. DESIGN: Retrospective study. ANIMALS: 265 feline dental patients. PROCEDURE: Full-mouth radiographs were examined for evidence of odontoclastic resorption lesions, periapical lucencies, periodontitis, and fractured teeth. RESULTS: Odontoclastic resorption lesions affecting 567 teeth were identified in 161 (60.8%) cats. Periapical lucencies were identified in 53 teeth in 35 cats. Periapical lucencies were most commonly associated with fractured teeth (25 teeth with periapical lucencies) and severe periodontitis (21 teeth). None of the periapical lucencies appeared to be specifically associated with resorption lesions. Prevalence of periapical lucencies in cats with resorption lesions was not significantly different from prevalence in cats without. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that although odontoclastic resorption lesions are common in cats, pulpal involvement associated with these lesions does not appear to be associated with development of radiographically detectable periapical lucencies. Crown amputation with intentional root retention may, therefore, be a suitable alternative to extraction in selected cats with odontoclastic resorption lesions.  相似文献   

Endometrial Adenocarcinoma and Mucometra in a 6-year-old Alaska Malamute Dog     

FJ Pena  JA Gines  J Duque  V Vieitez  R Martinez –Pérez  L Madejón  I Nuñez Martinez  JM Moran  S Fernández-García 《Reproduction in domestic animals》2006,41(2):189-190

A 6-year-old female Alaska Malamute dog was presented for evaluation of abdominal enlargement referred by a local veterinarian. On the history, the owner complained of chronic abdominal enlargement initiated more than 4 months ago, reduced appetite, occasional vomiting and general dullness. He also complained of greenish mucous intermittent vaginal discharge starting 10 days ago. The bitch was chronically treated with medroxiprogesterone acetate. A laparatomy was performed and fluid in the abdomen was found and aspirated during the surgery. Also a very fluid-filled distended uterus and a mass in the distal part of the left uterine horn were found. The mass was encapsulated by the omentum, but areas of necrosis and calcification were identified. Histopathological diagnosis was endometrial adenocarcinoma.  相似文献

Oral and maxillofacial osteosarcoma in dogs: a review     

N. Farcas  B. Arzi  F. J. M. Verstraete 《Veterinary and comparative oncology》2014,12(3):169-180

Osteosarcoma in dogs is a heterogeneous disease entity with regard to its histologic, clinical and biologic behaviour. Differences in behaviour are associated with tumour location. Oral and maxillofacial osteosarcomas are typically reported as a component of the broader classifications of axial osteosarcoma or osteosarcoma of flat bones to differentiate them from appendicular osteosarcoma. Similar to human oral and maxillofacial osteosarcoma, in dogs, these also appear to have less aggressive behaviour than appendicular osteosarcoma. Ideally, local control is achieved with wide surgical resection that results in tumour‐free margins. Failure of local control is the most common contributor to poor prognosis. Chemotherapy and radiation treatment are reported to have variable outcomes. The aim of this article is to review the literature on oral and maxillofacial osteosarcoma in dogs in comparison to appendicular and axial osteosarcoma. Similarities and differences between oral and maxillofacial osteosarcoma in humans are addressed.  相似文献   

The expression of calretinin and cytokeratins in canine acanthomatous ameloblastoma and oral squamous cell carcinoma     

A. Fulton  B. Arzi  B. Murphy  D. K. Naydan  F. J. M. Verstraete 《Veterinary and comparative oncology》2014,12(4):258-265

Oral squamous cell carcinoma (OSCC) and canine acanthomatous ameloblastoma (CAA) represent two epithelium‐derived neoplasms that affect the oral cavity of dogs. The expression of cytokeratins (CKs) and calretinin has been previously established in the canine tooth bud and odontogenic tumours. The aim of this study was to characterize the CK and calretinin expression profile of OSCC in comparison to CAA and canine tooth bud tissues. Samples from 15 OSCC and 15 CAA cases, as well as 6 tooth buds and 2 normal gingival tissues were examined. OSCC CK expression was consistent with the CK expression profile of CAA and canine tooth bud tissue. Calretinin was positively expressed in 10 of 15 OSCC cases, with 5 cases demonstrating high staining intensity. Only 2 of 15 CAA cases demonstrated mild‐moderate staining intensity. The statistically significant difference in staining pattern and intensity of calretinin in OSCC and CAA can help distinguish between these two tumour types.  相似文献   

Nitrogen removal techniques in aquaculture for a sustainable production   总被引：1，自引：0，他引：1  

Roselien Crab  Yoram Avnimelech  Tom Defoirdt  Peter Bossier  Willy Verstraete   《Aquaculture (Amsterdam, Netherlands)》2007,270(1-4):1-14

As the aquaculture industry intensively develops, its environmental impact increases. Discharges from aquaculture deteriorate the receiving environment and the need for fishmeal and fish oil for fish feed production increases. Rotating biological contactors, trickling filters, bead filters and fluidized sand biofilters are conventionally used in intensive aquaculture systems to remove nitrogen from culture water. Besides these conventional water treatment systems, there are other possible modi operandi to recycle aquaculture water and simultaneously produce fish feed. These double-purpose techniques are the periphyton treatment technique, which is applicable to extensive systems, and the proteinaceous bio-flocs technology, which can be used in extensive as well as in intensive systems. In addition to maintenance of good water quality, both techniques provide an inexpensive feed source and a higher efficiency of nutrient conversion of feed. The bio-flocs technology has the advantage over the other techniques that it is relatively inexpensive; this makes it an economically viable approach for sustainable aquaculture.  相似文献
