Requirement for MHC class II positive accessory cells in an antigen specific bovine T cell response   总被引：1，自引：0，他引：1  

E J Glass  R L Spooner 《Research in veterinary science》1989,46(2):196-201

Purified populations of bovine antigen presenting cells (APCs) and T cells have been isolated from peripheral blood and characterised using various monoclonal antibodies (mAbs) for cell surface markers. Bovine APCs were found in an adherent cell fraction and were non-specific esterase positive, phagocytic and expressed bovine major histocompatibility complex (MHC) class II determinants, all of which are typical macrophage characteristics. T cells were rigorously depleted of accessory cell function before being used in an antigen presenting cell assay. The generation of T helper cells in response to the soluble antigen, ovalbumin, was entirely dependent upon a critical number of APCs. Further the proliferative response was inhibited by several mAbs to bovine MHC class II molecules. Thus the interaction between bovine APCs and helper/inducer T lymphocytes (TH/I) appears to be similar to that in other species.  相似文献

Percutaneous absorption of chemicals: developing an understanding for the treatment of disease in frogs          下载免费PDF全文

V. K. Llewelyn  L. Berger  B. D. Glass 《Journal of veterinary pharmacology and therapeutics》2016,39(2):109-121

The permeable nature of frog skin presents an alternative route for the delivery of therapeutic chemicals to treat disease in frogs. However, although therapeutic chemicals are often topically applied to the skin of frogs, their pharmacokinetics have rarely been reported. To provide evidence to guide both candidate drug and formulation selection, we highlight factors expected to influence percutaneous absorption through frog skin, including the anatomy and physiology of the skin and the physicochemical properties of applied therapeutic chemicals. Importantly, we also highlight the effects of the formulation on percutaneous absorption, especially the inclusion of potential penetration enhancers as excipients. Finally, we collate empirical data on the topical application of various therapeutic chemicals in postmetamorphic frogs and show that, in contrast to mammalian species, even large chemicals (i.e. >500 Da) and those with a wide range of log P values (?4 through +6) are likely to be absorbed percutaneously. Topical application in frogs thus promises a convenient and effective method for delivering systemic treatments of a diverse range of chemicals; however, further experimental quantification is required to ensure optimal outcomes.  相似文献   

Characterization of house dust mite and scabies mite allergens by use of canine serum antibodies     

Schumann RJ  Morgan MS  Glass R  Arlian LG 《American journal of veterinary research》2001,62(9):1344-1348

OBJECTIVE: To identify the major allergenic proteins from the 3 main species of dust mites to which dogs react (Dermatophagoides farinae, D. pteronyssinus, and Euroglyphus maynei) and evaluate the potential cross-reactivity of dust mite allergens with antigens from the ectoparasitic mite Sarcoptes scabiei var canis. SAMPLE POPULATION: Sera from 83 dogs with atopic dermatitis. PROCEDURE: Sodium dodecylsulfate-polyacrylamide gel electrophoresis and immunoblotting using serum from atopic dogs was used to identify IgE-binding proteins in extracts of the 4 mite species. RESULTS: Sera of atopic dogs contained IgE against 23, 17, 25, and 17 allergens from D. farinae, D. pteronyssinus, E. maynei, and S. scabiei, respectively. Unlike the situation for humans, the major allergens for dogs are mostly proteins that are larger than 90 kd molecular weight. Dermatophagoides farinae and E. maynei appear to be more allergenic for dogs than is D. pteronyssinus. Some dogs with serum IgE against dust mites also had IgE against antigens of S. scabiei var canis. CONCLUSIONS AND CLINICAL RELEVANCE: Multiple dust mite allergens induce an IgE response in dogs. These allergens are mostly greater than 90 kd molecular weight.  相似文献   

A modified bilateral transfrontal sinus approach to the canine frontal lobe and olfactory bulb: surgical technique and five cases     

Glass EN  Kapatkin A  Vite C  Steinberg SA 《Journal of the American Animal Hospital Association》2000,36(1):43-50

Five adult dogs presented for an acute onset of seizure activity. Magnetic resonance imaging revealed lesions in the olfactory bulbs, frontal lobes of the cerebrum, or both. A modified bilateral transfrontal sinus craniotomy was performed on each patient. The goal of removing the lesion was to relieve clinical signs and to provide tissue for histopathological diagnosis. In each instance, excision of the lesion was possible using this approach. No postoperative complications were observed. The modified bilateral transfrontal sinus craniotomy provides excellent access to the canine olfactory bulbs and frontal lobes.  相似文献   

Short-term survival and mortality rates in a retrospective study of colic in 1588 Danish horses

Background

Outcomes of colic treatment are of great interest to clinicians, horse owners and insurers. One commonly used criterion of success is the overall short-term survival rate. This is used as to compare treatments and to measure quality of veterinary care, but may be biased by demographic or social factors such as attitudes towards animal suffering and euthanasia. The aims of this study were to 1) describe and analyse characteristics in horses with signs of colic referred to the University Hospital for Large Animals (UHLA), University of Copenhagen, Denmark over a 10-year period and 2) to compare these rates with those published in other comparable studies.

Results

The overall survival rate for colic horses over the 10-year study period was 68% (confidence intervals (CI): 66–71%; 1087/1588). In the medical group, 1093 horses, short-term survival was 87% (CI: 85–89%). Thirty one % of referred horses were given diagnoses requiring surgical intervention (CI: 29–33%). In this group 32% of the horses were euthanized before surgery (CI: 28–36%; 159/495). Of the surgical cases 27% (CI: 23-31%) were euthanized or died during surgery. Of the horses that recovered from surgery 25% died or were euthanized (CI: 19–32%; 48/189), while 75% survived to discharge (CI: 68–81%).

Conclusions

The short term survival rates of Danish horses with colic were similar or lower to those reported from other countries. Apart from variability of veterinary care, attitudes towards euthanasia vary among the countries, which may bias the outcomes. This study indicates that qualitative interview studies on owners’ attitudes towards animal suffering and euthanasia need to be conducted. Our opinion is that survival rates are not valid as sole indicators of quality of care in colic treatment due to selection bias. If the survival rates are to be compared between hospitals, techniques or surgeons, prospective studies including mutually agreed-on disease severity scores and a predefined set of reasons for euthanasia are needed.  相似文献   

Light level thresholds for visual reaction of mackerel, Scomber scombrus L., to coloured monofilament nylon gillnet materials     

G. Cui  C. S. Wardle  C. W. Glass  A. D. F. Johnstone  W. R. Mojsiewicz 《Fisheries Research》1991,10(3-4):255-263

A continuously swimming school of 12 dark-adapted mackerel was challenged to show visual reaction to barriers made from horizontal parallel lines (5 cm apart) of either monofilament nylon (0.40 mm diameter) gillnet material or, for comparison, the more visible twisted multifilament nylon (1.73 mm diameter). Six colours of each material were tested. The barriers were placed across the path of the approaching mackerel school while their behaviour was observed at low intensities of green light arranged to mimic undersea conditions. At very low light levels, the mackerel swam without hesitation through the barrier, whereas at higher light levels they turned or paused, indicating that they visually aware of the presence of the lines. The light level thresholds for visual reaction for the six colours of monofilament nylon were between −0.06 and −1.0 log lx, and for the same colours of twisted multifilament nylon were between −1.8 and −3.6 log lx. These findings are discussed in relation to the natural intensities of light in the sea, and the prediction of the visibility of drift and gillnet materials.  相似文献
