Portal hypertension in a dog due to circumscribed fibrosis of the wall of the extrahepatic portal vein.

A two-and-a-half-year-old German shepherd dog with ascites and a high concentration of blood ammonia was investigated. Sonographically, its liver was normal but the portal vein was dilated and the flow of blood within it was slow. A liver biopsy showed that the liver was normal, and did not reveal any possible cause of portal hypertension or ascites.

Doppler ultrasonographic diagnosis and anatomy of congenital intrahepatic arterioportal fistula in a puppy.

A dilated, tortuous blood vessel was identified sonographically in the right medial liver lobe in a puppy with severe ascites. This vessel was thought to represent the dilated right medial portal vein branch. Using pulsed wave Doppler ultrasonography, retrograde, abnormally pulsatile flow was detected in both the dilated right medial portal vein branch and the main portal vein.

[Vulvar discharge before parturition and a risk factor for postpartum diseases of the sow and for early postnatal piglet losses].

Periparturient biotechniques with prednisolon are widely used in Europe for the prevention of perinatal losses in intensive pig production. However, the routinely applied 100 mg prednisolon on the 113th day of pregnancy to the sow are not without controversy. In four intensive pig production units altogether 2143 sows treated thus were subjected to the evaluation of the following parameters: A: the presence or absence of vulvar discharge at the 110th day of pregnancy B: postparturient disease of the sow C: early postnatal piglet losses The results showed that the sows having prepartal vulvar discharge developed after prednisolon application significantly (p < 0.

[Contribution to therapy of the "prostate syndrome" in aged dogs].

The treatment of the "prostate syndrome" is a great challenge for the practicing veterinarian. In the present paper the therapeutic approach of this syndrome will be evaluated. 58 older dogs showing this syndrome were castrated and received thereafter oral antibiotic therapy.

A mouse monoclonal antibody reacting with swine leukocytes: a flow cytometrical and immunohistochemical study.

A mouse monoclonal antibody (Mab) was prepared by immunization of Balb/c mice with porcine peripheral blood mononuclear cells. Its reactivity was studied by flow cytometry and immunohistochemistry. By flow cytometry 75-90% of blood lymphocytes and 93-97% of blood granulocytes showed positivity, while all monocytes were labelled.

Comparative study of glial fibrillary acidic protein (GFAP)--immunoreactivity in the rat and monkey cerebellum.

Vibratome sections of perfusion-fixed rat and monkey cerebella were incubated with an antiserum to glial fibrillary acidic protein (GFAP). Immunolabelled elements showed in both species a principally similar distribution but the presence of long, transverse branches of Bergmann fibres was found to be characteristic to the monkey cerebellum. It is concluded that current methods enable fine interspecies differences of GFAP-localization to be demonstrated.
