Mercury poisoning cases have been reported in many parts of the world, resulting in many deaths every year. Mercury compounds are classified in different chemical types such as elemental, inorganic and organic forms. Long term exposure to mercury compounds from different sources e.g. water, food, soil and air lead to toxic effects on cardiovascular,(More)
Some studies showed that piperine (the alkaloid of piper nigrum) can change the activities of microsomal enzymes. Midazolam concentration is applied as a probe to determine the CYP3A enzyme activity. This study was done to determine piperine pretreatment role on midazolam plasma concentration. Twenty healthy volunteers (14 men and 6 women) received oral(More)
Oropharyngeal mucositis is an important complication in non-surgical cancer treatments. It represents the major complication in radiotherapy of tumors located in head and neck areas. Many results have been published in order to define the best clinical protocol for prophylaxis or treatment of mucositis, but a consensus has not been attained yet. In this(More)
Sperm premature chromatin condensation (PCC) has been considered as the second cause of failed fertilization post-intracytoplasmic sperm injection (post-ICSI). Cytoplasmic factors, including oocyte cytoplasmic immaturity have been suggested to induce PCC sperm. However, recent studies suggest that sperm chromatin anomaly might also lead to PCC sperm. During(More)
Background and Objective. Bisphenol A (BPA) is an abundantly used xenoestrogenic chemical which may cause various disorders in body. In the present study, we sought to investigate the effects of various doses of BPA on hepatic oxidative stress-related gene expression in rats. Methods. Male Wistar rats weighing 150-200 g were used in this study. Three doses(More)
BACKGROUND Treatment of chronic constipation is creating one of the major problems for doctors and patients. Pyridostigmine increases the gastrointestinal motility through the effects on cholinesterase. It seems that this mechanism can reduce chronic constipation. The aim of this study was to compare the effects of pyridostigmine and bisacodyl on chronic(More)
BACKGROUND Nonylphenol (NP) is one of the most widely used synthetic xenoestrogens in detergents, plastic products, paints and the most important environmental degradation factor. In this study, the effects NP was investigated on hepatic oxidative stress-related gene expression in rats. METHOD Wistar male rats weighing 150-200 g were divided into control(More)
BACKGROUND Bisphenol A (BPA) and nonylphenol (NP) have harmful effects on the endocrine system of humans and animals. AIM We sought to investigate the effect of three doses of BPA and NP on the reproductive parameters of rats. MATERIALS AND METHODS Adult Wistar male rats weighing 150-200 g were used for a consecutive 35-day study. BPA and NP were given(More)
INTRODUCTION Bisphenol A (BPA) and Nonylphenol (NP) have estrogen-like activity, and some of their adverse biological effects have been demonstrated. This study was designed to determine the association of plasma and tissue concentrations of BPA and NP and changes in the parameters of the reproductive system in rats. METHODS Male Wistar rats were(More)
BACKGROUND Azithromycin (AZM) is used in periodontal infections. The present study compared gingival crevicular fluid concentration of azithromycin of two pharmaceutical companies through the HPLC method. METHODS Two groups (n=15) of healthy volunteers participated in this study. The first group received an imported azithromycin (ImAZM) tablet (250 mg,(More)
