Inflammatory middle ear disease of the dog: the clinical and pathological features of cholesteatoma, a complication of otitis media     

C J Little  J G Lane  C Gibbs  G R Pearson 《The Veterinary record》1991,128(14):319-322

During a study of inflammatory middle ear disease in the dog cholesteatoma was found to accompany otitis media in seven of the 62 ears examined (11 per cent). The clinical, radiological and pathological findings in these animals imply that cholesteatoma in the dog is an aggressive lesion which must be differentiated from uncomplicated otitis media.  相似文献   

Ovariectomy as treatment for granulosa cell tumor in a heifer   总被引：1，自引：0，他引：1  

R R Leder  V M Lane  D P Barrett 《Journal of the American Veterinary Medical Association》1988,192(9):1299-1300

A granulosa cell tumor in a 15-month-old heifer was associated with abnormal udder development, relaxation of the pelvic ligaments, and nymphomanic behavior. After surgical removal of the tumor, the anatomic changes were reversed, and the nymphomanic behavior subsided. The heifer conceived 3 times thereafter and became a productive dairy cow. In previously reported cases of granulosa cell tumor, ovariectomy was unsuccessful in returning the cow to normal breeding.  相似文献   

TERMINATION OF EARLY PREGNANCY IN EWES BY USE OF A PROSTAGLANDIN ANALOGUE AND SUBSEQUENT FERTILITY     

R. N. Tyrrell  J. G. Lane  C. D. Nancarrow  P. J. Connell 《Australian veterinary journal》1981,57(2):76-78

SUMMARY Of 87 Dorset ewes injected at 20 to 60 days of pregnancy with either 125 μg or 250 μg of the prostaglandin F^2α analogue, cloprostenol, 72 (83%) were detected in oestrus by teaser rams within 7 days. A total of 60 ewes mated with fertile rams 14 to 28 days after treatment and 36 of these (60%) subsequently lambed. Thirty-eight ewes mated with fertile rams 29 to 56 days after treatment and 30 of these (79%) subsequently lambed. The difference in fertility between the 2 periods was not significant.
Six additional ewes which did not respond to the cloprostenol lambed normally within 6 weeks. They were more than 100 days pregnant when treated.
In ewes which first exhibited oestrus by 7 days of treatment, plasma progesterone concentrations fell from near 4 ng/ml to 0.6 ng/ml within 48 h of treatment. In ewes not detected in oestrus progesterone concentrations did not decrease to similar low levels (1.4 ng/ml; t-test p < 0.005). Concentrations in the 6 ewes treated near 100 days of pregnancy dropped from 7.4 to 4.4 ng/ml over 48 h. Overall, the progesterone concentrations indicated that 92% of ewes treated at 20 to 60 days of pregnancy experienced rapid luteolysis in response to the cloprostenol.
There were no differences between the 2 doses of cloprostenol in the responses or subsequent fertility of the ewes.  相似文献

Equine paranasal sinus cysts: a report of 15 cases   总被引：2，自引：0，他引：2  

J G Lane  J A Longstaffe  C Gibbs 《Equine veterinary journal》1987,19(6):537-544

The clinical and radiographic features of 15 cases of paranasal sinus cysts are described. Breed, sex and side frequency were unremarkable but two distinct categories of age incidence emerged. Onset of signs had occurred before one year of age in three cases, while all but two of the remaining 12 animals were older than nine years. The most common clinical signs were nasal airway obstruction, facial swelling and nasal discharge, often occurring in combination. Radiographic changes were recorded in all horses. Sinus opacification was a consistent finding and in several cases the bone surrounding the sinus had increased in thickness. Increase in intra-maxillary sinus pressure was demonstrated by septal displacement on ventro-dorsal radiographs in almost half the cases. Less common signs included expansion, free fluid accumulation within the affected sinus, dental distortion and displacement and mineralisation. Two horses were destroyed without treatment but in 13 animals surgical exploration was performed. Two of these were destroyed, one at the time of surgery and one five days postoperatively. In the remaining 11 cases, all accessible parts of the cyst were removed through a facial flap and drainage to the nasal meati was established. All these horses recovered satisfactorily and were followed up for periods between three months and six years without evidence of recurrence. Thirteen cysts arose in the caudal maxillary sinus and one each in the frontal and rostral maxillary compartments. Histopathological examination of portions of the cyst walls suggests that, like ethmoidal haematomas, they may originate from episodes of haemorrhage beneath the upper respiratory tract mucosa.  相似文献   

Hemochromatosis in Salers Cattle     

John K. House BVMS    Bradford P. Smith  John Maas  V. Michael Lane  Bruce C. Anderson  Thomas W. Graham  Michael V. Pino 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1994,8(2):105-111

Two 2-year-old Salers cattle from different herds raised on pasture were evaluated for retarded growth and diarrhea. Increase of liver enzyme activities and prolonged sulfobromophothalein (BSP) half life (T1/2) indicated liver disease with impaired liver function. Histopathologic examination of liver biopsies revealed a micronodular cirrhosis with marked deposition of hemosiderin in hepatocytes, Kupffer cells, and arterioles. Transferrin saturation (TS) and liver iron content were markedly increased, consistent with a diagnosis of hemochromatosis. Both animals were euthanatized due to deterioration in their condition. Necropsy findings included hepatomegaly and hemosiderin accumulation in the liver, lymph nodes, pancreas, spleen, thyroid, kidney, brain and other glandular tissue. Continued surveillance of the second herd (serum iron, total iron binding capacity [TIBC], unsaturated iron binding capacity [UIBC], and TS), identified a heifer as a hemochromatosis suspect in a subsequent generation. Liver biopsies from that animal revealed the same histopathologic changes as the previous 2 animals, and similar increases in liver iron content (8,700 ppm, normal range 45 to 300 ppm). The 3 affected cattle were all products of line breeding programs and shared a common ancestor. The absence of dietary iron loading in conjunction with the histopathologic and metabolic findings were consistent with a diagnosis of primary hemochromatosis. The reported disease is similar to idiopathic hemochromatosis in human beings in which there is a hereditary defect in iron metabolism.  相似文献   

Comparison of values derived from selected flours by fat acidity methods of the American Association of Cereal Chemists and the International Organization for Standardization     

R H Lane  R L Erickson 《Journal of the Association of Official Analytical Chemists》1988,71(3):569-570

Fat acidity values were determined on 8 commercially available flours by the American Association of Cereal Chemists method (AACC-02-01A) and by the International Organization for Standardization method (ISO-7305). Comparisons of means obtained by these 2 methods indicated that the ISO method produced results that were 1.4-2.5 times greater (P less than 0.001) than those for the AACC method. These data are consistent with a previous report which indicated that acidic materials (phosphates and amino acids) other than fatty acids are extracted by 95% alcohol (ISO method), whereas fatty acids alone are extracted by petroleum ether (AACC method). Fat acidity values obtained by AACC methodology employing Soxhlet and continuous extraction were also compared. No difference in fat acidity means existed with respect to extraction technique except for an aged whole wheat flour sample which produced a higher value (P = 0.05) by continuous extraction.  相似文献   

An evaluation of tympanometry, otoscopy and palpation for assessment of the canine tympanic membrane     

C J Little  J G Lane 《The Veterinary record》1989,124(1):5-8

Three techniques for the assessment of the integrity of the canine tympanic membrane were evaluated experimentally. Tympanometry, an objective technique, was shown to be very accurate for the evaluation of the integrity of the ear drum. Otoscopic examination by experienced personnel was shown to be moderately accurate under controlled conditions when the external ear canal was not inflammed. However, under field conditions when otitis externa was present, visual inspection of the tympanic membrane was seldom possible even after lavage of the ear. Palpation of the tympanic membrane with a blunt probe was shown to be very inaccurate and led to rupture of the tympanic membrane in a high proportion of cases. These results imply that two widely used techniques for the examination of the canine tympanic membrane are unsatisfactory. Furthermore, they suggest that previous reports of the prevalence of ear drum perforations in dogs may need reappraisal. Tympanometry is a non-invasive, objective and practical technique for the assessment of ear drum integrity which is worthy of further evaluation.  相似文献
