conclusions the results of the present study indicate the protective effects of melissa officinalis on some sperm parameters and spermatogenesis quality in rats exposed to lead. background some medicinal plants with their antioxidant properties have protective effects on sperm parameters and neutralize the harmful effects of lead exposure. objectives the present study aimed to determine the eff...

background: there are controversial reports about the exact mechanisms of lead-induced hypertension, but many factors such as alteration in the responsiveness of cardiovascular system to endogenous substances including catecholamines could be one of the mechanisms involved. in present study, the effect of exposure to 100 ppm lead acetate by drinking water (in the periods of 4, 8 and 12 weeks) o...

introduction: wistar rats are an outbred strain of albino rats belonging to the species rattus norvegicus. histopathological studies on the testis was carried out to determine the effects of heat and lead on male fertility by evaluating some andrological parameters of the wistar rat such as morphology of spermatozoa, sperm count and motility. the main objective of this research was to compare t...

objective(s) during recent years, there has been an increasing interest in contribution of environmental pollutants as heavy metals to human male infertility. present study was aimed to investigate the effects of maternal lead acetate exposure during lactation on postnatal development of testis in offspring rats. materials and methods a total of 60 female rats randomly divided into four equal g...

results long-term exposure to lead acetate caused histopathology effects including dilatation, congestion, nuclei heterochromatic effects, increase in diameter of renal tubules and urinary barrier thickness in rabbit renal tissue. conclusions quantitative and qualitative results of long-term lead acetate exposure showed many histopathology side-effects, especially in the urinary barrier. materi...

background: lead, an example of heavy metals, has, for decades, being known for its adverse effects on various body organs and systems such that their functions are compromised. objective: in the present study, the ability of lycopersicum esculentum on decrease toxic effects of lead acetate on plasma superoxide dismutase, catalase and malondialdehyde in rat. lead to adversely affect the liver t...

  In this study, the effects of lead acetate on two types of pain (nociception and inflammation) induced by formalin and its interaction with the opioid system and morphine-induced analgesia were examined. Male albino mice weighing 22-27 g were used in the experiments. Morphine was administered subcutaneously 30 minutes before formalin injection. Lead acetate was intraperitoneally administered ...
