The Effects Of Methotrexate On The Development Of Neural Tube Defects In The Chick Embryo^#, H. Seda Vatansever, A. Şükrü Umur, V. Sevi̇nç İnan, Mehmet Selçuki̇

Turkish Journal of Veterinary & Animal Sciences

During chick development, one of the earliest differentiated tissues is the neural tube. After 24 h of incubation, a chick egg starts to differentiate and 30-48 h after incubation the neural plate is closed from head to tail to form the neural tube. If factors controlling the neural tube's closing are disrupted, this consequently causes neural tube closure defects during this time. In this study, the effect of methotrexate on the developing neural tube was investigated during early chick development. For this research, 40 specific pathogen free (SPF) white Leghorn type chick embryos were used. They were incubated for 30 …

The Effect Of Rainbow Trout (Oncorhynchus Mykiss Walbaum, 1792) Cage Culture On Benthic Macrofauna In Kesikköprü Dam Lake*, İlknur Karaca, Serap Pulatsü

Turkish Journal of Veterinary & Animal Sciences

The aim of this research was to determine the effect of a cage farm with a capacity of about 55 t on the benthic macrofauna in Kesikköprü Dam Lake. At 3 stations (the cage and 15 m and 60 m from the cage) selected for this purpose the abundance and composition of benthic macrofauna were determined for 11 months. The abundance of benthic macrofauna (individuals/m^2) between the stations was statistically significant (P < 0.05). The abundance of benthic macrofauna was higher at the cage station than at the other 2 stations, except in April and November. During the research period the lowest number of individuals (937 individuals/m^2) was found at the second station 15 m from the cage in February; and the highest number (14,091 individuals/m^2) was determined at the cage station in December. Members of the class Pelecypoda were found at all 3 stations. Dreissena, which is a member of the class Pelecypoda, was the most dominant benthic organism (54%), followed by Chrinomus (30%) and Tubifex (11%). At the cage station, while members of the class Pelecypoda were found, no members of the classes Insecta, Oligocheta or Crustacea were found. The highest number of benthic macrofauna genera (7) was found at the station 60 m from the cage in April and November. The lowest number of genera (1) was found at the cage station in July. The results of this study in Kesikköprü Dam Lake reveal that the cage culture has a localizing effect on the abundance and composition of benthic macrofauna.

Glucose 6-phosphate dehydrogenase (G6PD) was purified from goose erythrocytes and some characteristics of the enzyme were investigated. The purification procedure was composed of 3 steps: hemolysate preparation, ammonium sulfate precipitation, and 2', 5'-ADP Sepharose 4B affinity gel chromatography. Thanks to the 3 consecutive procedures, the enzyme, having a specific activity of 36.2 EU/mg protein, was purified for a yield of 68.79% and 3892 folds; to ascertain enzyme purity, SDS-PAGE was performed. Optimal pH, stable pH, optimal temperature, molecular weight, and K_m and V_{max} values for NADP^+ and glucose 6-phosphate (G6-P) substrates were also determined for the enzyme. In addition, K_i …
