Experimental groups of pigs were treated orally with 120 mg (Group O 120), or 480 mg (Group O 480) of iodine per animal, or intramuscularly with 240 mg (Group I 240) of iodine per animal. Iodine was administered in the form of iodised fatty acid esters (IFAE). The treatment resulted in significantly increased iodine concentrations in tissues and a single dose was sufficient to meet the requirement for the whole fattening period (180 days). Urinary iodine concentrations in all the experimental groups were higher than in the control group C receiving iodine only from conventional feed. Urinary excretion of iodine between days 2 and 5 was more distinctive...

The testosterone production by Leydig cells of mice adversely affected with nutritional or social factors and exposed to chronic stress was studied in vitro. Both basal and gonadotrophin stimulated testosterone production were highly significantly decreased (P < 0.01) as in groups given the hypothyreotics or potassium nitrate alone as in combination with stress. Stimulated in vitro testosterone production was not significantly changed in groups fed with synthetic diets, however, in mice given modified diets and exposed to stress decreased responsivity of Leydig cells stimulated by gonadotrophin was found. Basal and stimulated...

Contents of aflatoxin B1 (AFB1) and ochratoxin A (OA) in the samples of wheat and barley were detected by RIA method. Average contents of AFB1 in the samples of wheat and barley were 2.4 µg/kg and 2.2 µg/kg, respectively. Average contents of OA in the samples of wheat and barley were 3.1 µg/kg and 2.4 µg/kg, respectively. The contents of mycotoxins corresponded to the allowed limits in food. During the studies of mutagenic activity of mycotoxins and their combinations by means of Ames test it was found that OA could increase the mutagenicity of AFB1 in the case of their simultaneous occurrence in the same substrate.

Numerous data point to the fact that Czech people played an important role in the cultural development of Croatia. Professor Josip Ubl was one of the many outstanding Czech veterinarians who greatly contributed to the Croatian veterinary medicine. Prof. Josip Ubl was born on the 4th April 1844 in Chudenice, in the Plzeň district. He descended from a respectable family, which highly influenced his schooling. He finished his primary and secondary education at his birthplace. He graduated from the k. u. k. Militär-Thierartznei-Institute in Vienna in 1867. Prof. Josip Ubl first worked as an assistant lecturer and as a professor of animal husbandry and...
