Determination of effects of smoke on the pelvic morphometry during growth period in the rat

Widespread smoking in the rooms existing children can cause important health problems. The harmful effects of smoking on the most body systems in the human beings and animals have been recorded in detailed. However, the studies about bone tissue have been commonly carried out in the periods of maturity and pregnancy and most of them have conducted about bone density. It has been seen that the datas obtained from these studies have not been contained the effects of smoking on skeleton system especially its development. In this study it is proposed to determine the effects of exposing to smoke on pelvis of the rats in the growth period, to determine more affected part of bones by smoke inhalation and also to determine any differences whether exist or not between males and females by morphomctric methods. For this aim, the Sprague Dawley rats were divided into two groups as an experimental and control groups. The experimental group was exposed to smoke inhalation for a period of 16 weeks after one week postnatally. Body weights, body and tail lengths, morphometric measurements of pelvis were taken both experimental and control group rats. As a result it was proved that there was a negative effect of smoke inhalation on body weight, body and tail lenghts and pelvis of the rats during the growth period. It was proved that the negative effect of smoke inhalation is more pronounced in males than females for the measurements of body weight, body and tail length as well as pelvis. It was thought that this study would contribute to useful knowledge the studies for the effects of smoking on human skeleton system, because the rats were mostly used as a model animals in the human medicine.
