Effect of exercise training on livers of young, old, and ovariectomized rats
ovariectomized rats 12 weeks after surgery were subjected to a 4 week treadmill-running program. In exercise groups, the rats were subjected to treadmill exercise during the time each rat walked on a motor-driven treadmill for 15 m min-1 speed and 15° incline once every 2 days for a period of 10 days over three courses for 5, 10 and 15 mins per day, totally for 30 days. In the stereological analysis of this study, the numerical density of the control groups were found significantly higher compared to ovariectomized and/or training groups (p<0.05). On the other hand, the liver cell numbers of ovariectomized
exercise-trained group was found to be lesser than other trained and ovariectomized groups. In addition, the cell density of ovariectomized group estimated as a little higher
than other groups except for control group (p<0.05).The stereological results revealed that ovariectomy and training can decrease the hepatocyte density in ovariectomized rats.
