Mining injuries in Serbian underground coal mines -- a 10-year study.

Mining, especially underground coal mining, has always been a dangerous occupation. Injuries, unfortunately, even those resulting in death, are one of the major occupational risks that all miners live with. Despite the fact that all workers are aware of the risk, efforts must be and are being made to increase the safety of mines.

Effect of olive oil on brain's lipid and calcium content after partial hepatectomy in mice.

The aim of this study was to investigate the influence of olive oil (00) enriched diet on the lipid content of mice brain during the early phase of liver regeneration and to test a relationship of these changes with calcium content. C57BI mice were fed over 21 days with diet enriched with olive oil, containing predominantly oleic acid (18:1n-9). The animals were one-third partially hepatectomised (pHx) under aether anaesthesia.

Metal tissue kinetics in regenerating liver, thymus, spleen, and submandibular gland after partial hepatectomy in mice.

Liver regeneration after partial hepatectomy (pHx) is a well-defined process, which involves the concerted action of extra- and intracellular factors resulting in induction of cell replication and its inhibition at the time when the entire liver mass is restored. Concomitantly, the breakdown of previously maintained tolerance and the exposure of self-antigens lead to the activation of preimmune and immune repertoires, which participate in surveillance against aberrant cells and the re-establishment of previous morphostasis. Because, in these events, important biological function might have tissue minerals that are affecting the structural integrity and enzyme activities, transduction signals, transcription and replication factors during cell proliferation and apoptosis, as well as the development and maintenance of immune functions and cytokine production, in this study we analyzed tissue dynamics of zinc, iron, magnesium, and calcium in the liver, thymus, spleen, and submandibular gland in intact and pHx mice on the 1st, 2nd, 7th, and 15th d after one-third pHx, using microwave digestion and inductivity coupled plasma spectrometry.

Effect of indomethacin on motor activity and spinal cord free fatty acid content after experimental spinal cord injury in rabbits.

Study Design: Determination of functional and biochemical parameters as well as the effect of specific therapies on these parameters, in the experimental model of neurotrauma in rabbits.

Objective: To assess the effect of indomethacin (0.1-3.

Determination of standard zinc values in the intact tissues of mice by ICP spectrometry.

The most commonly encountered difficulties for the quantitative measurement of zinc in biological samples are the limited sample amount, total and effective digestion of connective and fatty residues, and low zinc concentrations. These problems often lead to the determination of lower zinc values than actually present, so that the sample preparation, digestion, and analytical procedure deserve careful attention. In this short communication, a new method for microwave tissue disintegration is described.
