[ 1 ] - بررسی اثر مواجهه صدا بر پارامترهای اسپرم (تعداد، تحرک و زنده ماندن) موش سوری
صدا به عنوان یکی از مهمترین آلاینده فیزیکی محیط کار محسوب میگردد که اثرات زیانآور آن روی موجودات زنده مکرراً مورد بررسی قرار گرفته‌اند. صدا با ایجاد اثرات منفی روی پارامترهای اسپرم‌ها میتواند به عنوان عامل مؤثری در تولید مثل محسوب گردد. در این مطالعه 16 سر موش سوری نر در دو گروه مورد و شاهد مورد استفاده قرار گرفتند. صدای مرکب با پهنای 500-8000 هرتز با تراز شدت صوتی 2 ±100 دسی‌بل به مدت 10 روز...
[ 2 ] - Effect of High Light Level on Sperm parameters in Mice
Background and aims: High light level of natural or artificial sources in some workplaces may be considered as a hazardous physical agent. The present study aimed to assess the effect of light level of 1000 lux on sperm parameters in mice. Methods: The subjects were assessed in two group including 1. Exposed (n= 6; exposed to light level of 1000 lux during 5 eight-hour days), 2. Unexposed ...
[ 3 ] - Removal of air ammonia in a spray tower by dilute sulfuric acid solution
Introduction: Workplace air quality is a very important factor in community health and is measured by measuring and evaluating airborne contaminants. One of these airborne pollutants is ammonia gas. Spray towers are important components of air pollution control. The aim of this study was to investigate the effects of using diluted sulfuric acid solution on the efficiency of ammonia removal in a...
[ 4 ] - Effects of Co-Exposure to Noise and JP-4 Jet Fuel on Hearing Loss in Rats
Background and Aim: Autotoxic substances such as JP-4 jet fuel can have negative effects on the auditory system by the various means such as cochlear dysfunction. The purpose of this study was to investigate the combined effects of exposure to JP-4 jet fuel and noise on hearing loss in rats, to determine the possible interference effects of these two risk factors on rat auditory system. Methods...
[ 5 ] - The Effect of Cellular Phone Microwave Radiation on Sperm Fertility Indices (Count, Motility, Viability and Morphology) in Mice
Background & objectives: Cell phone microwave (MW) is one of the most harmful physical agents in modern society. This study was designed to determine the effects of exposure to cell phone microwaves on mice sperm morphologic indices. Methods: Animals were divided into two groups including: Microwave (MW) (n=6; exposed to 950-MHz cell phone MW with 5 W output power density and 200 KHz modulatio...
