Surgical correction of double-chambered right ventricle in dogs     

Martin JM  Orton EC  Boon JA  Mama KR  Gaynor JS  Bright JM 《Journal of the American Veterinary Medical Association》2002,220(6):770-4, 768

Double-chambered right ventricle (DCRV) is possibly an emerging congenital cardiac anomaly in dogs. The defect causes clinical and pathophysiologic signs similar to those of congenital pulmonic stenosis in dogs but has distinct diagnostic features, breed predilections, and implications for treatment. The defect is often associated with clinical signs early in life. Surgical correction of DCRV can be undertaken with the aid of cardiopulmonary bypass and offers the prospect of an improved clinical outcome.  相似文献   

A comparison of the cytologic and histologic features of meningiomas in four dogs     

Zimmerman KL  Bender HS  Boon GD  Prater MR  Thorn CE  Prater D  Robertson JL  Saunders GK  Sponenberg DP  Inzana KD  Lanz OI  Wright E 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2000,29(1):29-34

Abstract: The cytologic and histologic features of 2 intracranial and 2 spinal (extramedullary cervical) canine meningiomas were compared. Cerebrospinal fluid analysis in 2 cases revealed mild, mixed cell pleocytosis, primarily composed of small lymphocytes and monocytoid cells, with a moderate increase in total protein concentration. Cytologic features suggestive of meningioma included cells with both epithelial and mes-enchymal characteristics and a tendency towards cell clustering. Tumor location also was useful in making a diagnosis. The 4 meningiomas differed histologically from one another, and included angioblastic, psam-momatous, meningotheliomatous, and microcystic anaplastic types, which conformed to a classification scheme for human meningiomas. The classification scheme could not be applied to cytologic specimens.  相似文献   

C-reactive protein, tumor necrosis factor α, and interleukin-6 in dogs with pyometra and SIRS

Objective: To determine the frequency of the systemic inflammatory response syndrome (SIRS) in canine pyometra and to evaluate the relationship between C‐reactive protein (CRP), tumor necrosis factor α (TNFα), interleukin‐6 (IL‐6), and SIRS. Design: Prospective clinical study. Setting: Veterinary teaching hospital. Animals: Fifty‐three clinical cases of canine pyometra and 19 healthy control bitches. Interventions: Upon admission to the veterinary hospital, history and physical examination findings, including previously defined clinical SIRS parameters, were documented. Blood samples were obtained for hematology and biochemical tests and for CRP, TNFα, and IL‐6 analysis. The diagnosis of pyometra was confirmed by histopathology of the uterus after ovariohysterectomy. After surgery, clinical SIRS parameters, length of hospitalization, and mortality were recorded. Measurements and main results: Pyometra dogs were grouped as SIRS positive (30/53; 57%) or SIRS negative (23/53; 43%). Logistic regression showed that CRP was the only parameter that significantly related to SIRS apart from the clinical criteria that define this syndrome. The mortality rate was low (2/53; 3.8%), and conclusions regarding association with SIRS could not be drawn. A positive SIRS status, high plasma CRP concentration, and high body temperature were variables that related to increased morbidity reflected by the length of hospitalization. Conclusions: SIRS was seen in 57% of canine pyometra cases and a positive SIRS status showed a positive association with prolonged hospitalization. The mortality rate was low (3.3%) among SIRS positive dogs, indicating that progression to multiple organ dysfunction syndrome (MODS) rarely occurs in surgically treated cases of pyometra. CRP was associated with SIRS and with prolonged hospitalization. Further studies of plasma CRP may be warranted in canine intensive care cases susceptible to development of SIRS and MODS.  相似文献   

Influence of salinity and dietary composition on blood parameter values of hybrid red tilapia, Oreochromis niloticus (Linnaeus) ×O. mossambicus (Peters)     

M C J Verdegem  A D Hilbrands  J H Boon 《Aquaculture Research》1997,28(6):453-459

The influence of salinity and dietary composition on blood parameter values (haematocrit, leucocrit, immature lymphocytes, mature lymphocytes, granulocytes, plasma osmolarity and total plasma protein) of red hybrid tilapia, Oreochromis niloticus (Linnaeus) x O. mossambicus (Peters), was studied. Two groups of tilapia were fed a high-protein diet while kept in fresh or brackish water, respectively, and compared with two groups fed a low-protein diet under similar environmental conditions. Treatments were executed in duplo. Results show that salinity influenced all cellular blood parameters except the haematocrit. Dietary composition influenced the total plasma protein and haematocrit, while all parameters changed as time progressed during the experiment. It was concluded that the environmental parameters investigated in the present study should be considered when estimating fish health based on blood parameter values.  相似文献   

The leucogram as an indicator off marine-cultured rainbow trout, Oncorhynchus mykiss (Walbaum), health in The Netherlands     

I L J A Peutz    R W A Oorschot    G R Johnson    B S Horney  J H Boon 《Aquaculture Research》1996,27(6):437-445

During a longitudinal survey from June until October 1987 cytological blood parameters of smoltified marine cultured rainbow trout, Oncorhynchus mykiss (Walbaum), were monitored. In this period, the trout were exposed to environmental stress resulting in summer mortality. The statistical analyses showed that the observed summer mortality was preceeded by a shift in the relative abundance of different peripheral white blood cells (PWBCs), from lymphocytic to extremely granulocytic, which was mainly attributed to mature granulocytes. It was concluded that changes in relative abundance of PWBCs can predict health disturbances in marine-cultured rainbow trout.  相似文献

Endocarditis caused by Corynebacterium sp in a dog   总被引：1，自引：0，他引：1  

R A Henik  T A Allen  R L Jones  W E Wingfield  J Boon 《Journal of the American Veterinary Medical Association》1986,189(11):1458-1461

Mitral valve bacterial endocarditis, caused by Corynebacterium sp, was diagnosed in a dog. The bacteria had characteristics unlike those commonly recognized for most species of Corynebacterium. The primary source of bacteremia was suspected to be a pilonidal cyst of the sacrum. The dog was treated with a first-generation cephalosporin for 6 weeks, and the pilonidal cyst was surgically removed. Physical examination 1 year after initial examination revealed no abnormalities other than a cardiac murmur. On echocardiographic examination 1 year after treatment, the vegetative lesion was still present; however, chamber dimensions had returned to normal. Wall thickness and contractility remained increased.  相似文献   

An attempt at implementing a holistic inclusive development model: Insights from Malaysia's land settlement scheme          下载免费PDF全文

This paper examines the influences of Malaysia's Federation Land Development Authority (FELDA) scheme in fostering inclusive rural development. Based on the model of holistic inclusive development, the paper investigates the performance of FELDA from four perspectives: social development, industrialisation, modernisation and basic needs. The main findings of the study indicate that, to a large extent, the scheme has successfully stimulated both the social and economic development of the community. Nonetheless, establishing a strong trust, social cohesion and rapport between the public authorities and community remain the main challenges in determining the success of this state‐led agenda. Moreover, keeping traditional values in the modern system will be the key principle for the sustainability of the programme if plans are made to adopt the scheme in other regions.  相似文献
