Effects Of Cadmium On Uterine Contractions In Different Species In Vitro, Haki̇ Kara, Kadi̇r Servi̇, Yaşar Akar

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to examine the effects of cadmium on oxytocin-induced myometrium contractions in rats, cows and cats in vitro. The frequency was 12.20 ± 1.2, 11.25 ± 2.7 and 10.70 ± 2.5/10 min, respectively, after 0.01 mM oxytocin induced with myometrial samples in rats, cows and cats. The peak amplitude was 3.84 ± 0.50, 3.44 ± 0.65 and 3.35 ± 0.45 g, respectively, after oxytocin induction. The frequency and peak amplitude decreased after the addition of 0.01 mM cadmium chloride (CdCl_2). The frequency was 1.2 ± 0.4 (p < 0.001), 2.5 ± 0.5 (p < 0.001) and 2.0 ± 0.6(p < 0.001), respectively, and the peak amplitude was 0.7 ± 0.3 (p < 0.001), 1.2 ± 0.2 (p < 0.001) and 0.8 ± 0.4 g (p < 0.001), respectively, in rat, cow and cat myometrium. Finally, the myometrium contractions were completely inhibited in the three species. In conclusion, the effects of cadmium may inhibit both calcium channels and the intracellular-induced mechanism.


Effects Of Different Concentrations Of Copper Alone And A Copper + Cadmium Mixture On The Accumulation Of Copper In The Gill, Liver, Kidney And Muscle Tissues Of Oreochromis Niloticus (L.), Baybars Sağlamti̇mur, Bedi̇i̇ Ci̇ci̇k, Cahi̇t Erdem Jan 2003

Experiments were conducted in two series for 1, 7, 15 and 30 days. In the first series, fish were exposed to 0.1, 0.5, 1.0 and 5.0 ppm of copper and in the second series to 0.1 + 0.05, 0.5 + 0.1, 1.0 + 0.5 and 5.0 + 1.0 ppm of copper and cadmium mixtures. No mortalities were observed during the experimental period. Accumulation of copper in the tissues and organs increased with increasing concentrations of copper and with longer exposure periods. Copper accumulation associated with copper + cadmium mixtures in the gill, liver, kidney and muscle tissues varied with the …


Effect Of Cadmium Accumulation On Total Protein Levels In Tilapia Nilotica, Mustafa Kalay, Cahi̇t Erdem Jan 2003

Effect Of Cadmium Accumulation On Total Protein Levels In Tilapia Nilotica, Mustafa Kalay, Cahi̇t Erdem

Turkish Journal of Veterinary & Animal Sciences

The aim of the present study was to determine the accumulation of cadmium in different tissues of Tilapia nilotica and to establish the influence of this accumulation on total protein levels in liver and kidney tissues. At the end of each experimental period; gill, liver and kidney tissues from the animals were dissected and their cadmium accumulation was determined using atomic absorbtion spectrophotometry. Liver and kidney tissues were homogenised to determine total protein levels. The protein contents of the tissue homogenates were determined by the Lowry method. Cadmium accumulation was higher in the gill, liver and kidney tissues. Cadmium primarily …
