Cisplatin administration influences on toxic and non-essential element metabolism in rats

Abstract

Nowadays several papers deal with the effectiveness and side effects of metal complexes, especially cisplatin, in cancer therapy. The excretion of essential metal elements from the body is a serious problem in the treatment, but there are no data concerning the distribution and metabolism of toxic and nonessential elements. Therefore our aim was to study the concentration of some of these elements after treatment with cisplatin. Male Wistar rats (n=20, 175-190 g) were randomly divided into 2 groups (n=10/group). The control group received 1% (w/v) methyl cellulose at 10 mL/kg body weight, p.o. by gastric gavage twice daily for 14 days, while cisplatin was injected i.p. in a single dose of 6.5 mg/kg body weight. Inductively coupled plasma optical emission spectrometry (ICP-OES) was used for measuring Al, B, Ba, Cr, Li, Ni, Pb, Pt, Sb, Si, Sn, Sr and V content in plasma, liver and kidney. Liver total scavenger capacity, diene conjugate content and malondialdehyde concentration were also determined. Cisplatin elevated the free radical reactions in the liver, although redox balance did not change significantly. According to the study it seems that the metabolism of Al, Ba, Cr, Ni, Pb, Sr were changed by the effect of cisplatin, and the most notable alterations were found for Al and Pb. Therefore, besides the toxic effect of and free radical induction by Pt, the side effects of increased levels of other toxic and non-essential elements have to be taken into consideration.

Altered element homeostasis and transmethylation ability in short-term polyphenol rich supplementation in hyperlipidemic animal model

“…Wet liver homogenate samples (0.5 g) were digested in the mixture of 3 ml HNO 3 (65%) and 2 ml H 2 O 2 (30%) in an open block digestion system with 200 8C heating, then it was transferred to a 10 ml volumetric flask and filled up with high purity water (18.5 MΩ). Measurements were carried out for Al, B, Ba, Ca, Co, Cr, Cu, Fe, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Si, Sn, Sr, and Zn with a Spectro Genesis simultaneous ICP-OES spectrometer (Spectro Analytic Instruments GmbH, Kleve, Germany) (Szentmihályi et al, 2014). Because of the use of isotonic KCl solution for the preparation, potassium concentration could not be measured.…”

“…A májmintákból 500-500 mg-ot 5 ml 65%-os salétromsav és 2 ml H 2 O 2 elegyével mikrohullámú feltáróban roncsoltunk. Az elemtartalmak mérésére SPECTRO GENESIS ICP-OES (SPECTRO, Kleve, Németország) és iCAP Q ICP-MS (ThermoFisher Scientific, Waltham, MA, USA) készüléket használtunk multielemes standardok (MU33 multielement standard, 100 mg/l, CPA-Chem Product, Stara Zagora, Bulgária és EPA30 multielement standard, 5-100 mg/l, Bernd Kraft GmbH, Duisburg, Németország) segítségével [27].…”
