Ovarian tumours have a low incidence in bitch. Endothelin (ET‐1) and endothelin A receptor (ET‐A) are overexpressed in human ovarian cancer. Twenty canine ovarian tumours and five normal samples were first evaluated by western blotting and then immunohistochemically for ET‐1 and ET‐A expression. Seventeen out of twenty tumours were ET‐1 positive. Eight out of twenty tumours were ET‐A immunohistochemically positive. At molecular level both proteins were proven to be expressed in normal as well as in tumour samples. Our results show that ET‐1 and ET‐A are overexpressed in canine ovarian tumours, suggesting a potential role of these two molecules in canine ovarian carcinogenesis. 相似文献

Abstract— Anaesthesia for oesophageal surgery presents very few peculiar features, and any sound anaesthetic technique will provide satisfactory results. It is considered that relaxant drugs have a definite place in anaesthesia for this type of surgery.

Fifty-two spontaneous canine mammary gland tumours (fibroadenomas (n = 8), tubulopapillary carcinomas (n = 9), solid carcinomas (n = 6), anaplastic carcinomas (n = 7), fibrosarcomas (n = 9), liposarcomas (n = 9) and osteosarcomas (n = 4) were analysed by computer-assisted nuclear morphometry in Hemacolor-stained cytological specimens. Computerized cytomorphometry
was performed and the nuclear area, nuclear perimeter and mean nuclear diameter of investigated tumours were assessed. A minimum
of 100 nuclei per lesion were examined. The statistical analysis revealed statistically significant differences between benign
and malignant neoplasms. The results indicated that computer-assisted nuclear morphometry could be used as an additional method
for differentiation of benign from malignant canine mammary gland tumours in cytological specimens. 相似文献

The Patnaik histological grade is a good method for the prediction of long-term mast cell tumour behaviour but it is influenced
by subjective inter-observer variations and intratumoral heterogeneity. The present study evaluated each of the histopathological
parameters used to formulate Patnaik’s grade in terms of prognosis and tested whether they have a different prognostic sensitivity,
thereby disclosing which could be considered more useful in the prediction of tumour recurrence and patient survival. Clinical
presentation (single or multiple tumours) was also considered as possible prognostic factor. The results demonstrated that
individual histological criteria together with multiple presentation may be of value in predicting the outcome of mast cell
tumours. Among these, invasiveness (β1.85; standard error 1.15) and the number of mitotic figures (β3.01; standard error 1.18)
showed high prognostic significance (Cox proportional hazard regression for censored data ; chi-squared = 15.52, degree of
freedom = 6, p = 0.016) and could serve as reliable prognostic indicators avoiding more subjective parameters such as cellular differentiation,
nuclear morphology and tumoural pattern.

Serum and Tissue Steroid Hormone Levels in Canine Mammary Tumours: Clinical and Prognostic Implications 下载免费PDF全文
FL Queiroga D Pérez‐Alenza A González‐Gil G Silván L Peña JC Illera 《Reproduction in domestic animals》2015,50(5):858-865
Hormonal dependency of canine mammary tumours (CMT) has been studied over the last few decades. However, studies assessing the prognostic and predictive potential of serum and/or tissue steroid hormone levels are still scarce in CMT. To the best of our knowledge, this is the first report relating serum and tissue levels of steroid hormones and prognosis in dogs. Serum and tumour tissue from 45 female dogs with spontaneous CMT were included in the study. Moreover, serum and normal mammary tissue from 13 healthy female dogs were also included as controls. Steroid hormones were determined by competitive enzyme immunoassay. Overall, levels of steroid hormones in serum and tissue homogenates were significantly different between malignant and benign mammary tumours (p < 0.01), except for progesterone (P4) serum levels that revealed no statistical differences between groups. In malignant tumours, oestrone sulphate (SO4E1), dehydroepiandrosterone (DHEA), androstenedione (A4), testosterone (T) and P4 elevated tissue concentrations were significantly associated with tumour relapse and/or distant metastasis during follow‐up. A significant association was found between elevated tissue SO4E1 (p = 0.003), 17β‐oestradiol (E2) (p = 0.036), DHEA (p = 0.022), A4 (p = 0.001) and P4 (p = 0.013) concentrations and shorter disease‐free survival and overall survival in female dogs with malignant mammary tumours. The high levels of tissue steroids found in cases of poor prognosis open the possibility of additional new therapeutic approaches. Future clinical trials will be needed to clarify the usefulness of targeting steroid hormones in the treatment of this neoplastic disease. 相似文献

Macro- and microscopical changes in the hooves of 14 cattle having a clinically established diagnosis of laminitis are described, Deviation of the pedal bone was found in 10 of the animals. In acute laminitis, the microscopical changes in the corium were hyperaemia, oedema, thrombosis and haemorrhages. Degenerative changes were found in the epidermis especially in the vicinity of thromboses of vessels in the corium. In chronic laminitis, arteriolosclerosis and arteriosclerosis were constant findings in the corium. There was also a high frequency of chronic thrombi and chronic granulation tissue. Prominent features in the lamellae epidermales were hyper- and parakeratosis. As judged from changes in arterioles and arteries, hypertension is suggested to be a pathogenetic factor in bovine laminitis.cattle; laminitis; histology; arteriolosclerosis; arteriosclerosis. 相似文献

A technique for reconstruction of the thoracic esophagus was evaluated in 13 dogs. A 9 x 10 cm section of transversus abdominis muscle was harvested, fashioned into a tubular graft, and vascularized via the greater omentum. The vascularized tube was advanced into the caudal thorax through the diaphragm at a second surgery 20 to 44 days after harvesting the section of the transversus abdominis muscle. A 5 cm section of caudal thoracic esophagus was replaced with the vascular tubular graft. One dog died because of incarceration of the intestine within the tube and two dogs were euthanized because of infected tubes. One dog died due to an anesthetic complication, one dog had a diaphragmatic hernia and died, and one dog died from pyothorax. Leakage of luminal contents at the anastomoses did not occur in any dog. Seven dogs survived both surgeries but showed deglutitory difficulty 6 days postoperatively due to the grafted esophageal segments becoming severely strictured in each case. Angiography demonstrated vascularization of the full thickness of the graft in each of the seven dogs. An unacceptably high incidence of infection and stricture formation made this technique unsuitable for clinical use. 相似文献
