    Eighty Swiss mice divided into 4 equal groupı as follow: Group I Negative controls (nonvaccinated with Newcastle Disease vaccine and did not receive any additional treatment); Group. Il was consisted of 20 mice that received ND vaccine only; Group III had 20 mice that were ND vaccinated and drunk nitrite water (0.4 gr/lt) and the last group IV, had equal number of mice that were immunostimulated with ND vaccination and was additionally treated with nitrate in their drinking water (0.4 gr./lt) for a period of 26 weeks. Three mice randomly selected from each group were used to obtain blood samples and histopathological evaluations by the termination. The respective HI tilers for groups were 2-², 2-⁶, 2-⁵ and 2-⁴.The second group (vaccinated controls) being highest and followed by the third and the fourth groups showed moderate severe to lymphoid hyperplasia in thymus, peripheral lymph nodes and payer patches observed by light microscopy. In some cases, as the result of this severe lymphoid response, some mononuclear cell infiltrations into kidney, liver and even into the lungs were detected. The strength of hyperplasia and resulting infiltrations were in agreement with the immunosuppressive potential of nitrate and nitrite administered in drinking water.

    Sığırların dengesiz ve düzensiz rasyonlarla semirtilmesi sırasında oluşan urolithiasis konusunda klinikopatolojik çalışma
    (Uludağ Üniversitesi, 1988) Mert, Nihat; Tanrıverdi, Meltem; Sönmez, Gürsel; Ertürk, Erdoğan; Uludağ Üniversitesi/Veteriner Fakültesi.
    A sum of 25 young bulls (25 test end 8 controls) feeding on imbalanced ration (1,5 kg wheat Straw, 8 kg wheat bran perday) and 8 control animals from Uludağ University 's Veterinary Educational and Research Farm were comparitively studied. Test group animals were belonged to a public feeding unit (feed fot) located in a village nearby a large city where the university is trying to help and educate surrounding farmers. The imbalanced feeding was conducted in the villager's own barns, under usual conditions and lasted 4 months. Urolithiasis was detected macroscopically in 13 of 25 bulls. Urinary stones were multiple and varied in size, shape, color and weights. Blood urea, uric acid and total proteins together with the complete urine analysis were carried out and the differences between test and control animals were statistically significant (Total protein p < 0.001, urea and uric acid p < 0.05). Histopathological examination of kidneys of urolithiasis observed bulls demonstrated some urinary stones in the pelvis and subacute to chronic glomerulonephritis in their renal cortex.
