Comparison of Toxic Metal, Trace Element and Macro Element Levels in Trout Cultivated in Latvia and Turkey
(Parlar Scientific Publications (p S P), 2018) Cilingir-Yeltekin, Asli
The advances in technology and industry pollute water resources. Pollution occurring due to environmental pollution threatens ecosystems and humans more with each passing day. Fish oils obtained from fish cultivated in water in the Baltic countries are imported by Turkey and many other countries. In this situation, the aim was to compare the toxic metal and macro element levels in trout cultivated in Latvia with the element levels in trout cultivated in Turkey. The rainbow trout (Oncorhynchus mykiss Walbaum 1792) samples used in this study had element levels (Be, B, Al, Ti, Cr, Mn, Co, Ni, Cu, Zn, Mo, Cd, Ba, Pb, Na, Mg, Si, K, Ca, Fe, As, Se and Sb) analyzed in heart, muscle, liver, gills, kidney, brain, intestines, gonads and tissues with an ICP-OES device. The analysis results are grouped as toxic elements (Be, Cd, Pb, Al, Ba, Ti), trace elements (Cu, Mn, Ni, Mo, Co, Si, Fe, Zn, Cr, B) and macro elements (Ca, Mg, K, Na). The analyses did not identify Be, As, Se and Sb elements in tissues. Our study determined the toxic metals in trout from both countries were not at dangerous levels; also, they were nutritional in terms of trace element and macro element levels.
Plasma Macro and Trace Element Levels of Male Rats Vaccinated With Gnrh Hormone
(Parlar Scientific Publications (p S P), 2018) Mis, Leyla; Eski, Funda; Cilingir-Yeltekin, Asli
GnRH hormone is important in both male and female reproduction. Chemical agents are preferred to prevent fertility in some animals. Trace elements play an important role in reproduction. In this study, it was aimed to investigate the changes in macro- and trace element levels in blood plasmas of 6th and 12th months of GnRH vaccination (Repro-Bloc (TM)) male rats. 50 male Wistar Albino rats were used in the study. Each rat in the experimental group was administered a single 200 mu l intramuscular dose of GnRH. The levels of Cu, Fe, Mn, Zn, Se, K, P, Ca, and Mg elements were determined by analyzing the collected plasma samples using inductively coupled plasma-optical emission spectroscopy (ICP-OES). It was determined that zinc, manganese and selenium levels of the trace elements showed statistically significant changes in the first 6 months and Cu and Fe levels were statistically significant (P<0.05). In the twelfth month, it was observed that the levels of Fe, Mn, Se and Zn trace elements differ statistically. In the macro elements, K, P elements in the first 6 months period and Ca, Fe and Mg element levels in 16 months period gave statistically significant results (P<0.05). Conclusions: It was observed that levels of macro and micro elements were affected in male rats administered GnRH vaccine for immunocastration
