Effects of paint thinner inhalation on serum testosterone synthesis and secretion were investigated in the male rat. A control group inhaled normal air ventilation. The remaining animals were divided into three groups and exposed to paint thinner in a glassy cage for 15 and 30 days. A group of animals was allowed to recover for 15 day after 30 days of exposure. Toluene concentration (the largest constituent in thinner, 66%) was set at 1500 ppm in the inhalation air. At the end...

This study was undertaken to examine the effects of leptin on testicular histology in mice. Animals were divided into two groups. Group I served as controls. Mice in Group II were injected daily with leptin for five days. All animals were killed by decapitation at the end of the experiment. The testes were removed and weighed out. Some of the testicular tissue specimens were used for light and electron microscopic examination. The remaining samples were processed for semiquant...
