From December 2005 to January 2006, nerve conduction velocities and skin temperatures of 20 healthy students were tested with questionnaire investigation. The results show that the nerve conduction velocities as well as skin temperatures present an obvious decline trend in a continuous draught, and that the nerve conduction velocities and skin temperatures have a definite linear relationship. Draught velocity is an important factor in winter that affects body comfort, and the subjects are sensitive to air velocity.展开更多

Spirometry was performed on site. 61.47% of the grain workers complained of one or more respiratory symptoms during or after exposure to airborne grain dust.The prevalence of various symptoms was significantly higher among grain workers than control subjects. 15.6% of the grain workers had episodes of grain fever. The mean values of V<sub>max75</sub>, V<sub>max50</sub>, and V<sub>max25</sub> was significantly lower for grain workers than control subjects, suggesting that the group of grain workers had evidence of small airway dysfunction. Pulmonary function abnormalities were associated with increased duration of employment in the grain elevator,smoking was also associated with deterioration of respiratory function.展开更多
