Zinc content in blood plasma and brain tissue of rats was studied by analytic mass-spectrometry with inductively coupled plasma. In control (saline-treated animal) zinc content in plasma was 3.6±1.4 mg/ml, in the liver - 12.5±2.5 mg/mg, in the spleen - 10.9±4.1 mg/mg, in the brain - 8.7±3.0 mg/mg. After a single intraperitoneal injection of zinc donator acizolum (24 mg/kg) zinc content decreased in all examined tissues, especially in brain. After a course of sequential acizolum injections (seven administrations during two weeks) essential elevation of zinc content in blood plasma and tissues investigated was detected. The maximal increase zinc concentration in blood plasma and liver was detected in 15 h after the last acizolum injections. Selen, calcium, copper and iron contents demonstrated a more complex behaviour. The obtained data suggest that prolonged acizolum administration has a significant impact on the bioelements content, and this should be taken into consideration when this zinc donator is used as a drug. |
