Requirements for veterinary research and the recruitment of veterinary surgeons into research

Veterinary science plays a crucial role in society and it is important that veterinarians are involved. However, there are concerns about a growing gap in the quality of veterinary science compared with other biomedical sciences, and about falling recruitment of veterinarians into research. Andrea Nolan and Massimo Palmarini, on behalf of the rcvs Research Subcommittee, discuss these concerns and the steps being taken to encourage more veterinary graduates into a career in research.     

Perceptions of animal physiotherapy amongst Irish veterinary surgeons

The aim of this study was to investigate veterinary surgeons' perceptions, knowledge and use of animal physiotherapy in the Republic of Ireland. A questionnaire was developed and sent to 200 veterinary surgeons, of which 97 were returned. Results indicated that 77 (79%) of respondents were aware of animal physiotherapists. Common sources of information included veterinary colleagues, owners and professional journals, with physiotherapists themselves and undergraduate training being less commonly cited. Awareness of animal physiotherapy was greatest amongst those working in equine practice (χ2 = 5.7, df 1, p = 0.017); they were more knowledgeable about its techniques (t = 2.806, df 75, p = 0.006) and more likely to refer (χ2 = 48.36, df 1, p = 0.0001). Seventy-four respondents (96%) thought that more research was necessary to increase the evidence base for animal physiotherapy. If this branch of physiotherapy is to develop, there needs to be increased interaction and co-operation between veterinary surgeons and chartered animal physiotherapists.     

Nitric oxide: a review for veterinary surgeons

Nitric oxide (NO) is an endogenous gas that serves as a biologic messenger in many physiologic processes including neurotransmission, blood-pressure control, the immune system's ability to kill tumor cells, and wound healing. NO is produced after oxidation of L-arginine by a family of nitric oxide synthase (NOS) enzymes. Two of the NOS enzymes are present continuously and are thereby termed constitutive NOS. One of the enzymes, inducible NOS, is not typically expressed in resting cells and is induced by various substances including endotoxin, some cytokines, and microbial products. Thus, NO often has paradoxical activities. When NO is over- or underproduced, it can result in potentiation of disease states with disastrous results. This review discusses the biochemistry of NO, its functions in normal and disease states, and therapy for modulating NO production in disease states.
