Effects of sodium humate (HuNa), containing 61.9% of humic acids in dry matter, on utilisation and retention of dietary iodine were investigated in balance experiments carried out in pigs. A control group was fed a commercial diet containing 0.1 mg of iodine per kg. The daily intake of iodine was 129.2 µg per animal or 4.08 µg per kg live weight. The recommended intake of dietary iodine is 0.25 to 0.30 mg per kg at 88% dry matter. The experimental group (HuNa) was fed the same diet supplemented with 3% of sodium humate which contained 0.5 mg of iodine per kg at 90.04% dry matter. The supplementation increased the daily intake to 141.4 µg...

We verified the influence of salbutamol on changes of glycoconjugates contained in tracheal goblet cells in rabbits by the oral administration of Ventolin™ syrup in the dose of 5 ml. Material for both conventional and lectin histochemistry was collected 15 and 30 minutes post exposure. Gradual decrease of percentage of goblet cells containing acid sialylated glycoconjugates was observed 15 minutes after administration. Thirty minutes after administration, neutral glycoconjugates-containing goblet cells were absent. The proportion of goblet cells containing acid sialylated glycoconjugates reached 50% of the value in control animals. Compared with...

: During the 18-year period (1974-1991), the lymphocytic thyroiditis with the finding of serum autoantibodies against thyroglobulin was diagnosed in 180 Beagle dogs (92 males and 88 females). In 107 of them (56 males and 51 females), hyperplasia of parafollicular cells was concurrently encountered. In further 11 cases (3 males and 8 females), solid cellular structures were found in the thyroid parenchyma, in 4 females combined with unilocular or multilocular lymphoepithelial cysts. Grimelius stain revealed the presence of parafollicular cells even at the periphery of cellular nests. Using the lectin histochemistry with Maackia amurensis agglutinin...

The stitching of artificially created opening in the stomach to the parietal peritoneum has been experimentally examined so that the missing resected part was covered with the abdominal wall. Stomach contents were in direct contact with the peritoneal surface. In contradiction to common opinions (the rise of peritonitis and subsequent death) all experimental animals (six pigs and ten rats) survived the operation without any apparent complications. Within eight weeks following the laparotomy ("a second look"), the artificial perforation was narrowed down partly with outgrown gastric mucosa and partly with new generated fibrous tissue. The results of...

In August 1999 there were netted and ringed passerines in the Naděje fishpond system in Třeboň area. 14 individuals of blackcap (Sylvia atricapilla) of both sexes and various age were caught. All individuals of this species had expressive pathological changes on feet. Histological investigations proved bird-pox (variola avium). No symptoms of this disease were found in other caught 11 species.

The task of applied research is not only to acquire new knowledge, through which it contributes to the development of economy, to the consumer protection or to the training of qualified experts. For state-supported veterinary research, this means striving to protect people's health against diseases transmitted from animals, food-born diseases, contamination of feed and foodstuffs by toxic xenobiotics, a reduction in food quality through the use of low-grade raw materials and an adverse effect of environmental pollution. The territory of the state must be protected against the infectious diseases and animals against the negative effects of environment...
