Mast cell tryptase levels in normal canine tissues.

Levels of canine tryptase from various tissues were quantified using a competition enzyme-linked immunosorbent assay (ELISA). The assay utilises an affinity-purified rabbit anti-tryptase antibody in the solid phase and alkaline-phosphatase conjugated tryptase together with unlabelled tryptase in the fluid phase. The assay will rapidly quantify 40-5000 ng ml-1 of tryptase in tissue extracts. Tissues from the skin, gut, liver and lung were studied, of which canine gut appeared to contain the highest levels of tryptase per milligram wet weight, which may suggest an important role for this enzyme at this site. This assay may prove valuable in assessing the role of mast cells in various disease states in the dog.

[Feed allergy in dogs and cats--not only a gastrointestinal problem].

Immunologically mediated reactions to foods are responsible for up to 10% of all allergic syndromes in dogs and cats. Skin lesions (pruritus, erythema and papules) represent the main manifestation (70 to 80%) compared to only 10 to 15% incidence of gastrointestinal signs in combination with skin problems or alone. Diarrhea, vomiting, low appetite, chronic weight loss, abdominal pain and lethargy are the most common signs involved in gastrointestinal food allergy. There exists no breed or sex predilection in dogs or cats; signs may occur at any time during life time. The immunological nature of the disease can only be guessed at from anamnestic and clinical features and must be verified by presence of lymphocytes, plasma cells, mast cells and eosinophilic granulocytes in histological specimens. At this time, the responsible allergen can only be identified in a restriction diet trial based on food which the animal has not been fed before, given exclusively for at least four weeks to the pet. Changing from one brand of commercial diet to another is not recommended. The diagnosis is conclusively proven by reproducing the symptoms by feeding the original diet after the elimination of signs on the new diet. The pet can then be fed on a commercial diet (or home-made food) without the offending allergen(s).

[Rhinoscopy in dogs and cats].

Rostral and caudal rhinoscopy in dogs and cats facilitates the investigation of the nasal cavity and accurate biopsy. Rostral rhinoscopy can be performed by rigid endoscopes; caudal rhinoscopy requires flexible endoscopes. Deep anaesthesia or additional analgesia with local anaesthesia is necessary. The nasal cavity is assessed by its form, colour, surface of the mucous membrane, hyperemia, plaques, lesions, and the secretion is assessed by its quantity, colour and viscosity. Foreign bodies and neoplasia must also be looked for. Case reports with abnormal findings are described.

[Bronchoscopy in small animals].

Indications for bronchoscopy, the equipment and technique performance in dogs and cats are presented. The method is invasive, therefore exact indications such as chronic cough of noncardial origin, foreign bodies, parasitic invasion, paralysis of the larynx or tumours are required. Bronchoscopy enables the surgeon to take samples of bronchial discharge.

[Comparison of the intradermal and prick tests for diagnosis of allergy in the dog].

The diagnosis of allergic dermatitis and respiratory disease is increasing in veterinary practice. Searching for the initiating allergen(s) can be done with several kinds of dermal tests. In four healthy dogs and in 18 patients with a dermal or respiratory allergy problem the intradermal and prick tests were compared. Intradermal test reactions were readily identifiable and correlated well with anamnestic investigations. The prick tests generally did not give easily interpretable reactions.

[Poxvirus infection in a cat].

For the first time, a poxvirus infection was diagnosed as an etiologic agent of dermal disease in a living domestic cat in Germany. A literature survey, the clinical symptoms of the infection and the diagnostic procedures are described. Poxvirus infections should be considered as a differential diagnosis in feline dermatologic problems.

[2 cases of secondary esophageal carcinoma in the cat].

Secondary esophageal carcinomas in two cats are described. The main symptoms were vomiting, dysphagia and regurgitation. The radiological examination revealed pathological alterations of the esophagus, endoscopy and biopsy provided in case 1 a certain and in case 2 a presumptive diagnosis intra vitam.
