    Diagnosis of Teat Stenosis in Dairy Cattle by Real-Time Ultrasonography
    (British Veterinary Assoc, 2000) Dinç, D. A.; Şendağ, S.; Aydın, İ.
    TEAT stenoses are a significant problem in terms of milk production, treatment time, and premature culling. Stenosis completely or partially prevents milk flow from teats, thus decreasing milk production and increasing the risk of infection (Alaqam and others 1990). A correct diagnosis of stenosis has a positive effect on treatment. Medl and others (1994) reported that inspection, palpation, catheterisation (probing), and checking the milk flow from the teat, all of which are used in the diagnosis of teat stenosis, can provide a tentative diagnosis of fibrotic proliferations of the teat.

    Follow-up Ultrasonographic Examinations in Pregnant Bitches - Evaluation of Frequency and Significance of Embryo Resorption
    (Schattauer Gmbh-Verlag Medizin Naturwissenschaften, 2010) Şendağ, S.; Dinç, D. A.; Çelik, H. A.; Aydın, I.; Wehrend, A.
    Objective: Follow-up ultrasonographic examinations in pregnant bitches to evaluate frequency and significance of embryo resorption. Material and methods: In 39 Kangal bitches the number of gestational sacs was measured and vitality of embryos/fetuses was evaluated by real time ultrasonography daily from the 15th till the last day of gestation. Results: Five bitches (12.8%) showed embryonic resorption and one of these bitches exhibited a complete resorption. Fetal death could be observed in four females and was related to a total loss of the litter. After the first evidence of embryonic death gestational sacs remained detectable for 8.6+/-0.5 days. The number of embryos of bitches with (10.8+/-1.8) or without embryo resorption (8.2+/-2.1) was statistically significantly different (p<0.05). On the other hand there was no statistically significant difference within the number of embryos of bitches suffering fetal death and bitches without embryo resorption (8.2+/-2.1) (p>0.05).A relationship between litter size and gestational length could not be verified (r = 0.15; p>0.05). Conclusion and clinical relevance: Due to these results the hypothesis is postulated that embryonic resorption is a kind of protective mechanism of the maternal organism against too large litter sizes.
