OBJECTIVES Regeneration of the pancreas is initiated by the tubular complexes that consist of a cluster of epithelia surrounded by the mesenchymal cells. They have the potential to become pancreatic lobes, but their growth stops before the complete regeneration of the organ. To elucidate the possibility that we could promote the regeneration of the pancreas, the potential for growth or differen...

Background: There are reports indicating that among the others, hypoxia is one of the testes threatening factors, which may occur intentionally or accidentally. Hypoxia could be created secondarily after some pathological conditions such as anemia. In this study we aimed to investigate the crocin protective effect on the testes parameters in the animals that were exposed against phenyl hydrazin...

Background: Glyphosate (GPT) is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf and grasses known to compete with commercial crops grown around the globe. According to United States environmental protection agency the chemical has been reported as a third class toxin. Present study was designed in order to evaluate GPT-induced detrimental effects on testicula...

Background: Saffron is widely used as a food flavor and has well known medicinal effects which have an effect on steroid and sexual hormones. The aim of present study was investigation of saffron orally administration on spermatogenesis index in stress induced rats. Materials and Methods: In present study, 160 male adult rats divided to four groups with 10 rats per each cage and with four repli...

Background: Gibberellic acids are naturally occurring plant hormones that are used in agriculture as plant regulators and enter animals and human cells through diet. This study was undertaken to investigate effects of gibberellic acid on testicular tissue of adult rats. Materials and Methods: Twenty seven adult male Wistar rats after a one week acclimatization period were randomly divided into ...

Reports indicate that one of the causes of harmful to the genital system, especially the testes stress. Stress could be created secondarily after some pathological conditions such as neurological diseases or environmental factors. One of the causes of stress could be scary voices, such as cat voice for mice. In this study we aimed to investigate the testes parameters in the animals that were ex...

Background: Opium, as the most widely known opioid in the world, has significant effects on reproductive organs, which can affect fertility and influence the next generation. This study was performed to investigate the effects of opium administration on histological changes and spermatogenesis indexes in the testis of adult male rats. Methods:A total of 50 adu...
