Introduction: Whole-body vibration is one of the factors which may have adverse effects on the comfort of passengers and crew of rail transportation vehicles. In this study, the probable impacts of whole-body vibration were explored on the convenience of the passengers of Tehran metro.   Material and methods: Planning, measurement, and pre-analysis calculations were mainly done based on ISO...

Background: Although ionizing radiation is a risk factor, it is a therapeutic agent for cancer. Objectives: The protective and defensive effect of L-Carnitine and vitamin E on gastrointestinal tract organs (liver, spleen and intestine) post whole body gamma irradiation exposure. Material and methods: 56 male albino rats, which were divided into four groups (14 rats per group); group (I): Contro...

The cost and complexity of commercially available devices for measuring whole-body vibration is a barrier to the systematic collection of the information required to manage this hazard at workplaces. The potential for a consumer electronic device to be used to estimate whole-body vibration was assessed by use of an accelerometer calibrator, and by collecting 42 simultaneous pairs of measurement...

Whole body vibration exposure of the train drivers working for State Railway Lines is assessed by referring to ISO standard 2631 -1 and EU directive 2002/44/EC. The vibration measurements were done in the cabins of suburban and intercity train drivers. Suburban train driver performs his job usually in standing posture. Whereas intercity train driver works generally in seated (bending forward) p...

All biomedical laser applications are based on the interaction of laser light with biological system. During the past decade considerable evidence has accumulated demonstrating that non-thermal exposure to laser can elicit cellular changes in the immune system. In the present study, we have analyzed the effect of laser on immune response in rats. A group of rats were exposed to 0.225 mu j/cm2 f...

BACKGROUND Back injuries are common in transit drivers, and can result in substantial direct and indirect cost to the employer and employee. Whole-body vibration (WBV) is one risk factor for drivers. Standards have been adopted (ISO 2631-1) to guide researchers in measuring and analysing WBV levels. Lately, a new standard has been added (ISO 2631-5) that takes impulsive exposures into account. ...

BACKGROUND Whole-body-vibrations are often associated with adverse health effect but the long term effects are less known. This study investigates the association between occupational exposures to whole-body vibrations, and subsequent transition to disability pension. METHODS A total of 4215 male employees were followed up for subsequent disability pension retirement. Exposure to whole-body-v...

background: ionizing radiation induces the production of reactive oxygen species (ros), which play an important causative role in cell death. the aim of this study was to investigate the protective effects of sulfated derivatives of neutral polysaccharides extracted from auricularia auricular (snaap). materials and methods: whole blood samples from healthy donors treated with snaap at different...

Prostate cancer is common and its etiology largely unknown; therefore, it is important to explore all potential risk factors that are biologically plausible. Recent literature suggests a relationship between whole-body vibration (WBV) and prostate cancer risk. The aim of this study was to determine whether occupational WBV was a risk factor for prostate cancer. Existing data, collected on 447 i...

In vehicle systems occupational drivers might expose themselves to vibration for a long time. This may cause illness of the spine such as chronic lumbago or low back pain. Therefore, it is necessary to evaluate the influence of vibration to the spinal column and to make up appropriate guidelines or counter plans. In ISO2631-1 or ISO2631-5 assessment of vibration effects to human in the view of ...
