Abstract
The clinical efficacy for weight loss and safety of dirlotapide in dogs were evaluated in two multi-centre studies with parallel designs. Overweight, adult dogs (n = 245) of various breeds were randomized to treatment with dirlotapide or placebo in a 2:1 ratio. Dirlotapide was administered orally once daily to dogs at an initial dose of 0.05 mg/kg/day commencing on day 0 and doubled after 14 days. Every 28 days, dogs were examined, weighed, body condition scores (BCS) were recorded, and dose was adjusted to meet weight loss targets. Each study comprised three consecutive phases: weight-loss (up to day 196); weight-stabilization (84 days); and post-treatment (28 days). pre-treatment feeding and exercise regimens were continued during treatment. Dirlotapide-treated dogs showed mean weight loss of 15.9% (study A) and 14.0% (study B) by the end of weight loss phase (up to day 196). Percentage weekly weight losses for dirlotapide were significantly greater than for placebo (P < or = 0.0002). Emesis and diarrhoea were experienced in both treatments but were more frequent with dirlotapide; resolution was spontaneous. BCS improved for 75.7-82.5% of dogs on dirlotapide treatment compared with 15.4-41.4% for placebo. Mean dirlotapide dosage at end of weight-loss phase was 0.38 (study A) and 0.29 (study B) mg/kg initial body weight/day. Dirlotapide was found to be clinically safe and effective in the reduction of body weight in overweight dogs.

Abstract
Tulathromycin was evaluated in the treatment of pneumonia in weaned pigs inoculated intranasally with Mycoplasma hyopneumoniae. Five days postchallenge, the pigs were randomized to treatment with a single IM administration of saline, a single IM administration of tulathromycin (2.5 mg/kg; day 0), or three IM administrations of enrofloxacin (5.0 mg/kg; days 0, 1, 2). Pigs were necropsied on day 12 or 13. Unchallenged controls remained healthy with no lung pathology. Compared with saline, coughing, mean lung lesion score, and proportional lung weight were significantly reduced and weight gain was significantly greater for tulathromycin-treated pigs (P < .05). Compared with enrofloxacin, there were no significant differences in proportional lung weight or weight gains, but coughing and lung lesion scores were greater for tulathromycin-treated pigs (P < .05). Tulathromycin was effective in the treatment of pneumonia following experimental infection with M. hyopneumoniae.

Abstract
The clinical efficacy of tulathromycin in the treatment of natural outbreaks of swine respiratory disease (SRD) was evaluated at five European sites. Pigs (1 to 6 months of age) exhibiting clinical signs of SRD were treated intramuscularly with tulathromycin (n = 247) at 2.5 mg/kg on day 0 versus either tiamulin (n = 102) at 15 mg/kg on days 0, 1, and 2 (Germany, the Netherlands, and the United Kingdom) or florfenicol (n = 20) at 15 mg/kg on days 0 and 2 (France). Actinobacillus pleuropneumoniae, Pasteurella multocida, and Mycoplasma hyopneumoniae infections were the most frequently diagnosed pathogens. For both tulathromycin-treated animals and those treated with tiamulin or florfenicol, there were significant (P = .0001) reductions in mean rectal temperature and the severity of abnormal clinical signs on days 2 and 10 compared with day 0. There were no significant differences (P > .05) between treatments in average daily weight gain. Tulathromycin was found to be safe and highly effective in the treatment of natural outbreaks of SRD.

Abstract
Circulating lymphocyte numbers are elevated in horses with the allergic skin disease sweet itch and skin lesions are typified by an infiltrate of eosinophils and mononuclear cells, the latter of which have not been fully characterised. The aim of the present study was to characterise the lymphocyte subpopulations in the circulation and skin of ponies with sweet itch by flow cytometry and a newly developed modified alkaline phosphatase immunohistochemical technique. Sweet itch ponies were found to have significantly greater numbers of circulating CD5+ and CD4+ T-lymphocytes than normal animals. Increased numbers of CD3+ T-lymphocytes, most of which were CD4+, and eosinophils were present in the skin of these animals following intradermal injection of a Culicoides antigen extract (97 +/- 21 vs. 449 +/- 49 CD3+ T-lymphocytes/mm2 in deep dermis of vehicle vs. antigen injected sites; 83 +/- 8% CD4+ T-lymphocytes at antigen injected site). T-lymphocytes, which are thought to be important in the pathogenesis of human allergic skin disease, may therefore contribute to the development of sweet itch lesions via the release of cytokines which can cause eosinophil accumulation and activation. An understanding of the pathology of this disease may lead to a more rational approach to therapy.

Abstract
A whole-body extract of Culicoides impunctatus induced a biphasic increase in oedema formation in ponies with insect hypersensitivity, with maxima after one and eight hours. The Culicoides antigen did not induce similar responses in ponies with no previous history of the disease. In insect-hypersensitive ponies the local administration of chlorpheniramine (12 micrograms) completely inhibited oedema formation in response to histamine (0.04 microgram) and to Culicoides antigen (0.5 microgram) at one hour, and the response to Culicoides antigen at eight hours was inhibited by 63 per cent. Chlorpheniramine also partially inhibited the accumulation of eosinophils and neutrophils induced by Culicoides antigen after two hours.

Abstract
It has been reported that equine peripheral blood mononuclear cells (PBMNs) do not proliferate in response to tetanus toxoid (TT) (Frayne and Stokes 1995, Research in Veterinary Science 59, 79-81). Here we demonstrate that lymphocyte proliferation responses to TT, which are characteristic of a recall antigen, may be achieved under certain culture conditions. Given that TT vaccination is routinely applied to many horses, TT is a suitable antigen for the investigation of cellular immune responses by peripheral blood mononuclear cells in the horse.

Abstract
An optical arrangement has been devised that will permit the measurement of one component of the relative displacement, and therefore the corresponding strain, in a surface at nonambient temperatures by use of coherent optics. The method is based on the technique of moiré interferometry with illumination at grazing incidence. A demonstration of principle is described, with the beams passing through the flame of a blowtorch.

Abstract
A high sensitivity technique combining lensless speckle photography and a grid technique is proposed and demonstrated. A high frequency grid is applied to the specimen surface and contact specklegrams are made in white light before and after loading, in the double exposure mode. Subsequent optical processing yields the various components of in-plane displacement. The sensitivity can be chosen equivalent to the grid frequency or multiples thereof. The method is simple and gives low-noise fringe patterns with high contrast. It is suitable for application in the mechanical laboratory and field environments, because vibration isolation precautions are not necessary.

Abstract
In the manufacture of holographic gratings using coherent light there is an associated problem of optical noise, the conventional remedies for which involve various restrictions. In this work a moving point source is adopted and analysis indicates that if the path is a circle several of these restrictions are removed. The scheme is implemented and the results are highly satisfactory with high-efficiency gratings being produced at frequencies up to 2400 lines/mm, in sizes up to 65 mm square. Significant operational advantages also accrue in relation to alignment procedures and light utilization.
