During 1985—1990 12 302 fodder samples were tested bacteriologically, including 303 g (24,7%) from fodder mixtures, 1585 (12,89%) from fish meal, 2905 (23,61%) from bone-meateal, 4054 (32,95%) from imported ground soya beans and peanuts 719 (5,85%) samples of protein- fat concentrate. Out of 12 302 tested samples 456 (3,71%) Salmonellae were isolated. Salmonella was most often isolated from protein-fat concentrate (14.88%) and bone-meat meal (8,57%). This bacterium was isolated with the lowest frequency from imported ground grain (0,69%) and fish meal (0,76%). The following serotypes were most commonly isolated: Salmonella choleraesuis, S. derby, S. isangi and S. typhimurium.

The examinations of the content of lead and cadmium in the liver and kidneys were carried out on 237 foxes which included 110 females and 127 males. The level of the tested metals varried greatly. The maximum content exceeded the minimal standart 89 times in the liver and as much as 123 times in kidneys, while the maximum content of cadmium exceeded the minimal standard by 43 times in the liver and 79 times in kidneys. It was noted that an average concentration of lead in males was greater than in females: 0.142 and 0.126 mg/kg in the liver, and 0.147 and 0.127 mg/kg in kidneys, respectively. The average concentration of cadmium in the liver was identical for both sexes, i.e. 0.036 mg/kg. However, the level of cadmium in the kidneys of males was higher (0.113 mg/kg) than in females (0.093 mg/kg). The highest concentration of the tested elements was found in foxes with reproductive disturbances.

The examinations were performed in 1988—1990. The purpose of the work was to investigate the survival of Salmonella in the soil and water. Salmonellae originated from dead or killed foxes and swabs taken from the vagina or anus. The isolated strains were classified as S. choleraesuis, S. dublin, S. enteritidis and S. typhimurium. Seedings were done on solid media, i.e. basic agar medium, the BGA, Endo, McConkey’s and Slavin’s media and liquid media, i.e. MK and SF. An average period of survival in the soil of individual serotypes was: S. choleraesuis — 257 days, S. dublin — 381 days, S. enteritidis — 451 days and S. typhimurium — 321 days. An average survival period in water was: S. choleraesuis — 18 days, S. dublin — 14 days, S. enteritidis — 25 days and S. typhimurium — 22 days.

The aim of the experiment was to examine the healing process of experimental wounds in 15 rats. The wounds of 9 rats were treated with 4% chitosan ascorbate (1st group), whereas the wounds of 6 rats were not treated at all (2nd group). In every rat two square skin flaps (10 mm x 10 mm) were cut out on the back in the scapular region. The proces of wound healing was surveyed for 21 days, the rate of crust formation was observed and the width and depth of crust was measured. On the 7th, 14th and 21st day of the experiment wound specimens were cut out for histopathologic examination. This examination assessed the surface of a wound (exudate, epidermis - coverage of defect surface, epidermal thickness expressed in the number of cell layers, characteristics of ripening - creation of granular and horny layer, occurrence of appendage buds) and the tissue filling up a defect (the number of capillary vessels, collagen and argentaffin fibres their number and thickness). The results of microscopic and histopathologic examination confirmed the usefulness of chitosan ascorbate in healing experimental wounds in rats. In rats treated with chitosan ascorbate the wound healing process was quicker, the wound shrank more quickly, the process of epidermis reconstruction was better, the scar was smaller, skin appendages - hair follicles and glands - were regenerated.

The content of iron, copper and manganese was tested in 237 foxes, including 110 females and 127 males. The level of the elements varied greatly in the liver and in the kidneys according to the sex of the foxes. The average concentration of iron and copper was much higher in the liver of males than that in females and also higher in the kidneys of females compared with that in males. The average concentration of manganese in the kidneys of foxes did not vary considerably in either sex. On the other hand, it was notably higher in the liver of males than in females. The average level of iron, copper and manganese was significantly higher in the liver than in the kidneys of foxes independent of sex.

В работе представили результаты гистопатологи- ческих исследований проб, происходящих от скощ, подозреваемого в бугристой форме лейкоза, с территории Гданьского и Эльблонгского воеводств. Представили статистические данные по интенсивности появления бугристой формы лейкоза, а также ее динамику и разницу в ее появлении между обоими воеводствами, а также сравнили число положительных и отрицательных результатов в обоих воеводствах. Результаты исследований объяли 1974—1984 гг. В общем исследовали 4089 коров, в том 1606 из Гданьского, а 2483 — из Эльблонгского воеводства. В исследуемых воеводствах распознали гистопаго- логически бугристый лейкоз у 98,09% коров. В 1974—1984 гг. в обоих воеводствах появились разные тенденции по развитию лейкоза: в Эльблонгс- ком воеводстве отметились понижение, в Гданьском же воеводстве рост заболеваний лейкозом скота.

The findings of histopathological examinations of the samples, taken from cattle with the signs of tumorous leukaemia and sent to the Veterinary (Diagnostic Laboratory in Gdansk, have been presented. Statistical data regarding the intensiveness of the disease, its dynamics and differences between two provinces were given; the positive and negative findings in the both districts were compared. The results concerned the period between 1974—1984. Altogether 4089 cows were examined: 1606 came from the Gdansk province and 2483 from the Elblgg district. Histopathological examinations confirmed tumorous leukaemia in 98.09%. Different trends as to the development of leukaemia were noted in the two districts: a decrease in the Elblgg province and an increase in the Gdansk district were observed.

Ferromagnetic foreign bodies of varied shape and lenght were inserted into the reticulum of 2 fistulated cows and afterwards the animals were given loose magnets. Manual examinations and 128 photographs taken by use of the intraoperative roentgenography showed that almost all foreign bodies were dispersed on the reticulum bottom. In the presence of the loose magnet, the objects located on its surface. In the walking animal the magnet was rolled and these displacements favoured easy picking up the foreign bodies. The ferrous materials were usually collected parallelly to the long axis of the magnet, displacing on its smooth surface. The significance of animal walking in treatment of traumatic reticulitis by use of magnets was discussed.
