A number of studies have shown that acute physical exercise is associated with the induction of apoptosis not only in skeletal muscle but also in many distant organs. One of the pathogenic agents responsible for exercise-induced damage in many tissues is the generation of oxygen free radicals. The aim of the present study was to examine the influence of exercise-induced oxidative stress on the rat kidney. The analysis was performed on the kidneys of rats subjected to treadmill running until exhaustion. Our results demonstrated that acute exercise led to apoptotic damage of the renal distal tubular cells, although this was not a result of oxidative stress.

Cytological studies of Daucus carota L. (cv. Karo) in suspension culture were made. Cells growing on medium without ammonium were larger and more vacuolated than were cells grown on the standard medium. Their sizes (cell area) ranged widely from 200 µrm2 to 40000 µm2. They also showed a very low level of aggregation (1%) as compared to an 81% frequency of aggregates in the standard suspension. Suspension deficient in ammonium had a .small percentage of 2-9-nucleated cells. Such multlnucleate cells were not observed in suspension with both nitrate and ammonium used as nitrogen source.
