    Cutaneous lesions associated with reo-like virus in a green lizard (lacerta viridis laurentı 1768)
    (Uludağ Üniversitesi, 2008) Dorrestein, Gerry M.; Uğurtaş, İsmail Hakkı; Özyiğit, Musa Özgür; Akkoç, Ahmet; Akkaya, Abdulmüttalip; Fen Edebiyat Fakültesi; Biyoloji Bölümü
    In this case, a green lizard (Lacerta viridis LAURENTI 1768) caught in Uludag, Bursa, north-western Turkey, was diagnosed as reovirus by electron microscopy. In the macroscopical examination, wart-like growths were seen on the dorsum of the animal on the skin between the forearms and on the back close to the pelvic region. In the microscopical examination of hematoxylin and eosin stained sections, hyperkeratosis, ballooning degeneration and eosinophilic inclusions in the cytoplasm were observed. There was no positive reaction for papillomavirus in immunohistochemistry. Electron microscopic study of these growths revealed the presence of viral particles belonging, from the morphological aspect, to the family Reoviridae.

    Relations between leptin and testosterone and glucose concentrations, fattening performance and reproductive development in growing bulls
    (Uludağ Üniversitesi, 2008) Doğrutekin, Deniz; Çetin, Meltem; Udum, C. Duygu; Veteriner Fakültesi
    This study were performed in 7 Brown Swiss and 7 Holstein bulls. The leptin concentrations at 12 months of age and testosteron concentrations at 9 months of age were statistically different between Brown Swiss and Holstein bulls (P < 0.05). In hip heights, a statistical difference at the level of P < 0.01 and P < 0.05 was observed at the 7, 11 and 12 months of age values and at the 8, 9 and 10 months of age values, respectively, between the two breeds of bulls. Furthermore, live weight gains and feed conversion values at 8 months of age were also significantly different (P < 0.05 and P < 0.01, respectively). Statistically negative correlations (P < 0.05) were observed between leptin concentrations and hip heights and scrotal circumferences of Brown Swiss bulls. The correlation was observed only between the leptin and testosteron concentrations in Holstein bulls (P < 0.05). In conclusion, the data obtained from Holstein bulls implies that leptin might be involved in growth and reproductive development, no association, however, was obtained between leptin and feeding performance.
