[ 1 ] - Nicotine-induced damages in testicular tissue of rats; evidences for bcl-2, p53 and caspase-3 expression
Objective(s): Present study was performed in order to uncover new aspects for nicotine-induced damages on spermatogenesis cell lineage. Materials and Methods: For this purpose, 36 mature male Wistar rats were divided into three groups as; control-sham (0.2 ml, saline normal, IP), low dose (0.2 mg/kg BW-1, IP) nicotine-received and high dose (0.4 mg/kg BW-1, IP) nicotine-received groups. Followi...
[ 2 ] - The Effects of Pyridaben Pesticide on the Histomorphometric, Hormonal Alternations and Reproductive Functions of BALB/c Mice
Objective(s): The adverse effects of pyridaben on reproductive system in male animals are not well established. This study was designed to elucidate how pyridaben can effects the histomorphometric, hormonal alternations and reproductive functions of BALB/c mice . Materials and Methods : For this study, 80 adult and apparently healthy male BALB/c mice were divided into three groups Viz, cont...
[ 3 ] - The Ultrastructural Changes of the Sertoli and Leydig Cells Following Streptozotocin Induced Diabetes
Objective(s) This investigation was conducted to evaluate the effects of diabetes on the structure and function of testicular tissue. Materials and Methods Diabetes was induced in male adult rats by a single intraperitoneal injection of streptozotocin. Body and testicular weight, hormonal analyses, histological and ultrastructural analyses were measured. Results The body and testicular we...
[ 4 ] - Effects of aflatoxin B1 on profiles of gonadotropic (FSH and LH), steroid (testosterone and 17β-estradiol) and prolactin hormones in adult male rat
Aflatoxins (AFs) are natural contaminants of feed and feedstuffs, thus the study of the noxious effects ofthese agents on the male reproductive system is of outstanding importance. Our aim for this study is theevaluation of the effects of oral administration of aflatoxin B1 on the reproductive hormonal changes in adult male rat. Twenty eight Wistar strain male rats were selected for this study....
[ 5 ] - Gross morphology, histomorphology and histomorphometry of the jejunum in the adult river buffalo
For this study the jejuni of 50 adult (2-4 years), apparently healthy Iranian river buffaloes were collectedfrom the abattoir for gross morphology, histomorphology, and histomorphometry. Our statistical analysisrevealed that, there are significant (P
