Naphthyl esterase and platelet-activating factor (PAF)-acetylhydrolase activities were detected in the salivary glands of the cat flea, Ctenocephalides felis. Salivary naphthyl esterase activity is disgorged during exploratory probing. Whole extracts of salivary glands contain esterase activity against the short-chain naphthyl esters alpha-naphthyl acetate(More)
We report the outcome of a 30-month programme to rederive 310 specific pathogen-free mouse strains to populate a new individually ventilated cage barrier facility at the Mary Lyon Centre (MLC), Medical Research Council (MRC) Harwell. The mice were rederived in a self-contained quarantine suite and embryo-recipient females were health-screened to assess(More)
This report summarises clinical and pathological observations on Fell pony foals with a range of signs that included ill thrift, anaemia, respiratory infection, glossal hyperkeratosis and diarrhoea. Some of the foals had normochromic, normocytic anaemia and some had low levels of plasma proteins, including immunoglobulin G. Antibiotic and supportive(More)
Rates of accumulation of, and radiolabel incorporation into, the major secretory product of the long hyaline gland, a glycoprotein LHPI, were used to examine the role of the corpus allatum (CA) and corpus cardiacum (CC) in the regulation of protein synthesis in the accessory reproductive gland of the male grasshopper, Melanoplus sanguinipes. Incorporation(More)
A six-week-old female borzoi puppy from a brother-sister mating developed a generalised illness characterised by anorexia, temporary intention tremor, episodic pyrexia, tachypnoea, conjunctivitis, otitis and neck pain. Haematological abnormalities included an inflammatory leukogram and regenerative anaemia. Blood cultures remained sterile; clinical(More)
A one-month-old female Dunkin Hartley guineapig presented with a thin hair coat and distended abdomen. Post-mortem findings after euthanasia were a protein-rich modified peritoneal transudate and heterotopic pancreas at a site of colon stricture and ulceration. Complications of pancreatic heterotopia are well recognized in man but not in animals. The(More)
An adult dairy cow developed acute fatal diarrhoea. Necropsy provided no aetiological or morphological cause of the diarrhoea but incidental post-mortem findings included well-circumscribed areas of jejunal squamous epithelium. The cause of this unusual heterotopia is not known, but the lesion may have been of embryological or metaplastic origin.
