today, with rapid advancement of industry and technology, many concerns about the adverse consequences threaten human life. The objective of this research is to investigate environmental education as an implement to reduce and evaluate the environmental consequences of petrochemical products based on the hierarchical analysis. The methodology was a survey of a statistical group involving 30 man...
Introduction: ADHD (attention deficit hyperactivity disorder) is a neuro-behavioral syndrome that is characterized by a lack of attention, irritability, high activity, distressed behaviors, especially in boys. Materials and Methods: A cohort study was conducted on 120 children aged 6 years. 60 children with low birth weight (less than 2500 g) as exposed group and 60 children with birth weight m...
Introduction: In this study, organ radiation doses were calculated for the renal agent 99mTc-DTPA in children. Bio-kinetic energy of 99mTc-DTPA was evaluated by scintigraphy and estimates for absorbed radiation dose were provided using standard medical internal radiation dosimetry (MIRD) techniques.Material and Methods: In this applied research, fourteen children patients (6 males and 8 females...
The safety of the stabilized, orally absorbable form of reduced nicotinamide adenine dinucleotide (NADH), known under the brand name ENADA, was investigated over a period of 26 weeks. Eighty healthy rats (40 males and 40 females) were divided into two groups. One tablet ENADA/NADH 5 mg per day was administered orally to one group while identical-looking white tablets not containing NADH (placeb...
In the internal dose evaluation, the specific absorbed fraction (SAF) and S-value are calculated from the reference phantom based on Caucasian data. The differences in height and weight between Caucasian and Asian may lead to inaccurate dose estimation. In this study, we developed the Taiwanese reference phantoms. 40 volunteers were recruited. Magnetic resonance images (MRI) were obtained, and ...
The aim of the present study was to investigate the testosterone-like effect of Kaempferia parviflora (KP). Castrated immature rats were randomized and divided into two groups (control and KP-treatment groups). The rats (n=7-8) were treated daily for 5 days by oral route with water in the control group and 1,000 mg/kg of KP in the treatment group. All rats were decapitated 24 h after their last...
Introduction: Organ dose estimation using thermoluminescence dosimeter (TLD) is known to be a standard, although many other methods, such as simulation software, optically stimulated luminescent dosimeters, and photodiodes are still in use. This study aimed at directly measuring mean organ doses to the selected organs in the head/neck, chest, and abdominal regions from four computed tomography ...
