In Vitro And In Vivo Effects Of Serine And Threonine On Follicle Growth, Differentiation And Atresia, Hüseyi̇n Baki̇ Çi̇ftçi̇
Turkish Journal of Veterinary & Animal Sciences
This work was designed to test the effect of serine and threonine on follicle growth, differentiation and atresia under in vitro and in vivo conditions. Two experiments were conducted. In the first experiment, follicles 90-120 µm in diameter, from 21-day old mice, were dissected mechanically and cultured individually for 7 days. Follicles were subjected to 4 different treatments. Follicles in medium without amino acids and gonadotrophins were assigned as control groups. Follicles in medium with PMSG and without amino acids constituted a positive control whereas the other treatments were test groups. Every 24 h follicle diameters were measured and the …

This study was performed to evaluate the feasibility of bone injection gun assisted intraosseous administration of contrast media as an alternative to the intravenous route for urography. Intravenous urographies were obtained in 6 rabbits. Urographic examinations by the intraosseous route were performed in the same animals 48 h later. After adequate anesthesia, the retroauricular vein was punctured for intravenous injection and a bone injection gun was used for intraosseous injections to the distal one-third of the rabbit femur. Direct radiographies of rabbits were obtained following 1200 mg/kg body weight iomeprol (300 mg iodine/ml) administration by both the intravenous and intraosseous …

The Treatment Of Experimental Acute Ethylene Glycol (Antifreeze) Toxication Using 4-Methyl Pyrazol And Ethanol In Dogs, Vehbi̇ Güneş, Çeti̇nkaya Şendi̇l
Turkish Journal of Veterinary & Animal Sciences
The effects of ethanol and 4-methyl pyrazole were investigated in the treatment of 30 dogs toxicated with antifreeze (AF). The AF toxication produced significant increases in blood urea, creatinin and potassium and a decrease in blood calcium levels. Calcium-oxalate monohydrate, which is pathognomic for AF toxication, was consistently seen in urine sediment. Ethanol was rarely effective on the multisystemic effects that occurred in dogs or ADH inhibition. CNS findings were also observed after ethanol administration. The results indicated that 4-MP treatment provided earlier and safer healing than ethanol. It was deduced that 4-MP + NaHCO_3 was more effective than ethanol …

Antibiotic Resistance And Plasmid Dna Contents Of Streptococcus Thermophilus Strains Isolated From Turkish Yogurts, Belma Aslim, Yavuz Beyatli
Turkish Journal of Veterinary & Animal Sciences
Thirty-four Streptococcus thermophilus strains were isolated from yogurt samples obtained from various villages in different regions of Turkey. These strains were examined for their antibiotic resistance patterns and plasmid carriage. The susceptibility of the isolates to 8 antibiotics (vancomycin, tetracycline, chloramphenicol, erythromycin, cephalothin, ampicillin-sulbactam, gentamicin and penicillin G) was determined by the disk diffusion method. Most strains of S. thermophilus were resistant to gentamicin (79%) and penicillin G (64%) and susceptible to chloramphenicol (94%) and tetracycline (88%). In plasmid DNA analyses, it was determined that 7 strains did not contain any plasmid DNA, while other strains included plasmid DNA ranging …
