    　View Summary

    We developed a new system for measuring accurate reaction times that was aimed to use in clinical settings. We tested the system for the driving assessment and for the assessment of attention disorder of people with brain injury. In the driving assessment, the results of our figure discrimination task were well matched with the on-road test comparing with some traditional neuropsychological tests. In the assessment of attention disorder, the results of our appearing stimulus task and detecting velocity change task were coincided with the result of behavior observations of the patients conducted by an experienced Occupational Therapist. These results suggest that our new system could be used for assessing patients objectively in clinical settings.

    　View Summary

    Inattention is one of the common symptoms in developmental disorders such as Learning Disabilities(LD) and Attention Deficit Hyperactivity Disorder(ADHD). It is known that the inattention develops symptoms of hyperactiveness, attention deficit and restlessness. Although the assessment of these symptoms is important from the viewpoints of treatment of patients and adjustment of patients' living environment, the effective evaluation methods are not established yet. We devised some reaction time tasks, in which multi-sensory stimuli were employed, to evaluate symptoms of inattention adequately. In this research, we investigated the relationships between each tasks and the symptoms of inattention. We also studied whether or not the changes in the symptoms after giving six months intervention of Occupational Therapy to the patients cause the changes in the reactions times of the tasks. As a result, it was suggested that the spatiality in presenting visual stimuli have major influence on the inattention of people with developmental disorders, and factors of spatial allocation and displacement in attention related to patients' daily behavioral characteristics. In addition, visual perceptual noises of displaying distractors behind the target stimulus had no influence on the reaction time when the position of appearing the target was fixed but had inference when the position changed spatially. From this result, we considered that the visual perceptual noises could have an influence in attention when spatial factor in attention is necessary to conduct the task. We confirmed that this characteristic was improved by having Occupational Therapy treatment, and patients having the improvement of symptoms of inattention after six months intervention of Occupational Therapy could have faster reaction times to the task related to the characteristic than those measured before having the intervention.

    　View Summary

    The prospective birth cohort with one obstetric hospital in Sapporo City has been conducted to investigate the association between child growth, neuro-development, and allergy, and low-level exposure to environmental chemicals during pregnancy, infancy and up to school age. A follow-up questionnaire was used at 18, 42, and 84 months of age to obtain relevant information including allergy prevalence, dietary habits, and smoking history of mother and the partner. The levels of PCDDs/PCDFs and PCBs in maternal blood and breast milk were measured using a high-resolution gas chromatography/high-resolution mass spectrometer (HRGC/HRMS). PFOS and PFOA levels in maternal blood were analyzed by liquid chromatography-tandem mass spectrometry (LC/MS/MS). We assessed the influence of low level intrauterine exposure of toxic chemicals on childhood neurodevelopment at 6, 18 and 42 months of age using the Bayley Scales of Infant Development second edition (BSID-II) and Japanese version of the Kaufman Assessment Battery for Children (K-ABC). The Japanese version of the Child Behavior Checklist (CBCL) was used to collect information on child behavior at age 43 months.

    　View Summary

    1. The prospective cohort study involving 514 pregnant women was carried out to investigate the effects of endocrine disruptors such as dioxins, PCBs and PFOS/PFOA on next generations. We have conducted a survey on each mother based on their daily diet, life styles, and occupation at their gestational period, 18 and 42 months after giving birth, and measured the associations between maternal blood concentrations of environmental chemicals and their effect on infant health.2. Since we found a negative relation between maternal blood concentration of Mono-ortho PCBs-TEQ and newborn's TSH Ievel,and a positive one between maternal blood concentration of Total PCDD/PCDFs-TEQ and newborn's FT4 level, it was supposed that PCBs and dioxin have no restraint on the infant's thyroid function.3. We have approved that PCDFs in maternal bloods have adverse effects on fetal development because of the negative associations between total PCDFs concentration in maternal bloods, birth weight and SGA.4. We conclude that exposure of dioxin in the uterus at the background-level may effect the fetal immuno-system because of the positive association found between the 33'4'4'-TCB in maternal bloods and the IgE level in umbilical bloods.5. We found that PCBs and dioxin concentrations in maternal bloods cause adverse effects on the neurological system of six-month-old children. This is seen to have effect on the physical development.6. Among PCDDS, PCDFs and Coplanar PCBs, only the concentration of Coplanar PCBs in maternal bloods had a positive correlation with mercury concentration in maternal hair. Our study suggested that genetic susceptibility to tobacco smoke may adversely affect fetal growth. Among infants born to smokers with the AhR wild genotype, CYP1A1 variant genotype, or the GSTM1 null genotype, birth weight and birth length were significantly reduced.
