Veterinary inspec­tors recorded the data obtained from meat inspection classification of 36 028 821 pig carcasses at slaughterhouses in theCzechRepublicduring the period of 1995-2002 together with the reasons for classification. The trends were evaluated by a comparison of two periods (Period I: 1995-1998; Period II: 1999-2002) by means of calculating the indexes of values from Period II compared to those of Period I. Pig carcasses classified as capable for human con­sumption (edible) were found in 97.28% of cases (97.26% during Period I and 97.31% during Period II, index 1.00), while those classified as capable for processing (conditionally edible) were found in 2.15% of cases (2.28% during Period I and 2.02% during Period II, index 0.89), and those condemned in 0.57% of cases (0.47% during Period I and 0.67% during Period II, index 1.43). The reasons for classifying the carcasses as condemned were as follows: sensorial changes in meat - 0.33% (0.26% during Period I and 0.41% during Period II, index 1.56), lesions due to non-infec­tious diseases - 0.12% (0.12% during Period I and 0.12% during Period II, index 0.97), added deleterious substances - 0.05% (0.03% during Period I and 0.07% during Period II, index 2.50), lesions due to respiratory infections - 0.03% (0.03% during Period I and 0.04% during Period II, index 1.70), boar taint - 0.02% (0.02% during Period I and 0.03% during Period II, index 1.36). Other reasons to condemn the carcasses included tuberculous lesions, lesions due to miscellaneous infections, digestive infections, parasitic diseases, and Salmonella infections. The occurrence of these conditions was on the level of mere hundredths of per cent. No case of Aujeszky's disease was found. According to the results of meat inspection classification, the risk of food-borne diseases originating from pig carcasses tends to be greater in the lesions due to non-infectious conditions with a long-term increasing trend. A considerable increase in the numbers of pig carcasses condemned due to added deleterious substances (index 2.50) is an alarming finding with regard to potential food safety hazards.

Twenty minutes after fertilization, one group of rainbow trout eggs was exposed to water temperatures of 26°C in duration of 20 minutes to induce triploidy. Second group was kept in water temperature of 10°C, which is optimal for development of rainbow trout. The frequency of micronucleated erythrocytes was determined in the peripheral circulation of rainbow trout 67 days (following absorption of the yolk - swim-up stage) and 128 days (fry stage) post fertilization. There was a significant difference (P < 0.001) between frequency of micronucleated erythrocytes of diploid (1.10 ± 0.96‰) and triploid (2.41 ± 1.28‰) fish at swim-up stage. Increased mean values of micronucleus in diploid (1.80 ± 1.57‰) and triploid (5.92 ± 3.80‰) fry were also recorded.

The examination focused on the functional parameters of sperm (motility, percentage of live sperma­tozoa, acrosomal integrity) and their morphology. The levels of relationship between individual criteria of sperm analysis were demonstrated. Statistically highly significant correlations between motility, ratio of live spermatozoa, percentage of intact acrosomes and percentage of spermatozoa with altered superficial structures were proven. Our findings proved the sensitivity of superficial structures, primarily plasmatic membranes, and the higher resistance of structures with an organelle basis. Strict morphological sperm analysis provides important information about the rise in qualitative alterations of ejaculates caused by changes in superficial structures during the course of a short-term survival test.

In cases where there is no response to catheterisation and medical intervention, surgery is needed to provide urination and correct uremia and hyperkalemia. Several surgical techniques have been described. The perineal urethrostomy technique, reported by Wilson and Harrison in 1971, has been used extensively and since then various modifications of this technique have been developed by other researchers. In 2000, Yeh and Chin described a modified perineal urethrostomy tech­nique created by use of the prepuce mucosa. This technique was used in our clinic in 20 cats with penile urethral obstruction. Seventeen cats recovered without complication. A 2.6 mm diameter catheter was placed in each of the 3 cases in which leakage was determined in the anastomosis site. The urine gathered in the site subcutaneously was drained. Normal urination was achieved in 2 of the 3 patients treated with this technique. The remaining case was re-operated and the perineal urethrostomy technique, in which the urethra was sutured to the perineal skin (the Wilson and Harrison method, 1971), was applied. The advantages of this technique over the classical perineal urethrostomy technique are; return to urination shortly after the operation, better urination potential compared to normal cats, a more aesthetic appearance compared to other techniques (similar to a castrated cat), no narrowing of the orifice caused by re-growth of hair. It was also understood that, anastomosis of the urethra and the prepuce mucosa must be carried out with utmost care in order to prevent urine leakage.
