AN OESOPHAGEAL DIVERTICULUM IN A DOG

An 11-month-old male Miniature Poodle was found to regurgitate small volumes of fluid and food particles due to a diverticulum in the thoracic oesophagus. The diverticulum was removed surgically. Histologically the wall contained extensive scar tissue. Longterm recovery was uneventful and 5 months after surgery the dog is in good health     

Influence of environment on adrenal cortical response to ACTH stimulation in clinically normal dogs.

Effect of testing environment on adrenal cortical responses to an injection of ACTH in clinically normal dogs was examined in three locations, presumably of increasing order of stress elicitation: in a home; veterinary hospital (VH), 4 hours in a cage; and VH, overnight in a cage. Basal cortisol (hydrocortisone) values for plasma were significantly lower (P less than 0.001) for the home group (1.8 microgram/dl) when compared with values for the VH, 4-hour cage (3.8 microgram/dl) or the VH, overnight cage (3.9 microgram/dl) groups. However, significant differences (P greater than 0.05) were not observed 2 hours after ACTH admininstration for the home group (13.7 microgram/dl); VH, 4-hour cage group (14.8 microgram/dl); or VH, overnight cage group (16.0 microgram/dl). Responses of individual dogs were consistent (P less than 0.005). The testing environment did not markedly affect results of adrenal cortical function tests for dogs when ACTH stimulation was utilized. The response of dogs to ACTH, as monitored by immunologic assay techniques (competitive protein-binding assay or radioimmunoassay), was consistent and was useful as a diagnostic aid for adrenal malfunction.     

Prolactin and colibacillus-induced fluid transport in ligated intestinal segments.

Two experiments, using the ligated intestinal segment technique, were conducted to determine whether the pituitary hormone prolactin (PRL) could reduce Escherichia coli-induced fluid loss into the small intestine of 2- to 3-week-old pigs. Inoculation of 10(6) to 10(8) enteropathogenic E coli organisms into ligated jejunal segments caused a significant accumulation of luminal fluid within 12 hours. In the first experiment, intraluminal inoculation with 0.5 mg of ovine PRL along with the bacteria did not have any effect on fluid accumulation. Systemic IV treatment of the animals with 1.0 mg of ovine PRL at 3-hour intervals, beginning either immediately after or 9 to 10 hours before intestinal ligation, did not significantly (P less than 0.05) reduce fluid accumulation as compared with control animals. In the second experiment, IM administration of 100 microgram of thyrotropin-releasing hormone (TRH) at 3-hour intervals, beginning 6 hours before intestinal ligation, significantly (P less than 0.05) increased circulating PRL concentrations, as measured by radioimmunoassay. However, TRH treatment did not reduce the accumulation of luminal fluid in E coli-inoculated segments.     

Newcastle disease in Cyprus: A review

Summary The first Newcastle disease epidemic in Cyprus was reported in 1949 to 1950 and between 1953 and 1959 there was a second. In November 1977 another Newcastle disease outbreak occurred. Measures implemented immediately were: quarantine of all foci of infection, destruction of diseased and in-contact birds, disinfection of premises and island-wide (Government controlled) vaccination. Within a month the epidemic was brought under control. In all 47 outbreaks were recorded with the loss of about 35,000 birds. Only 2 commercial units were affected, the remaining outbreaks occurring in premises of back-yard poultry keepers. The virus was the Asiatic type.

La Enfermedad De Newcastle En Chipre: Revisión De La Literatura

Resumen La primera epidemia de Newcastle en Chipre se describio en 1949–50 y la segunda entre 1953 y 1959. En Noviembre de 1977 ocurrio otro brote. Las medidas tomadas fueron: cuarentena de todos los focos de infección, destrucción de todas las aves enfermas y en contacto, desinfección de los galpones y vacunación general. La epidemia se controló en un mes. En los 47 brotes diagnosticados, hubo una pérdida calculada de 35 000 aves. La enfermedad se diagnosticó en dos empresas comerciales y en unidades pequeñas familiares. El virus aislado fue el tipo Asiático.

La Maladie De Newcastle A Chypre—Revue

Résumé La première appartition de la maladie de Newcastle à Chypre, a eu lieu en 1949–1950, avec une seconde vague entre 1953 et 1959.La maladie est répparue en 1977. Les mesures assitôt prises ont été: la mise en quarantaine des foyers d'infection, la destruction des animaux malades et des animaux contaminés, la désinfection des locaux et une large vaccination, sous contrôle officiel, des volailles de l'Ile. En l'espace d'un mois la maladie a été enrayée. Pour les 47 foyers constatés les pertes se sont élevées à environ 35 000 têtes. Deux élevages commerciaux ont seulement été atteints, les autres foyers étant apparus dans les poulaillers des petits éleveurs.
