The influence of some optical environments on the blood pressure control system was examined using the sun optical simulator. We used adult cats in which the telemetry device for measurement of arterial blood pressure had been implanted. The arterial blood pressure of the cat under free action was continuously recorded every Smsecs for 24 hours. Heat rate was measured by observing the peak interval of the arterial blood pressure wave form. The optical environment was examined using three kinds of spectrum, solar spectrum (280nm-2800nm), visible spectrum (400nm-750nm), and ultraviolet spectrum (290nm-400nm). The irradiation was conducted for three hours, between 19 :30 - 22 :30.The mean arterial blood pressures, the max dp/dt, and the heart rate increased significantly during the first 30 minutes under the irradiation, and quietened down afterwards. These changes were similarly observed in all three kinds of spectrum, solar spectrum, visible spectrum, and ultraviolet spectrum. In addition, when the wavelet transform analysis was attempted to calculate the max dp/dt change, a characteristic change of a level of about 0.016Hz was observed.These results show the existence of a regulation mechanism which is stimulated by irradiating light. This reaction is similarly obtained with ultraviolet rays.

利用太阳光学模拟器研究了光学环境对血压控制系统的影响。我们使用的成年猫中，用于测量动脉血压的遥测装置已被植入。在自由活动状态下，每隔1 μ s连续记录猫的动脉血压，持续24小时。通过观察动脉血压波形的峰值间隔来测量心率。利用太阳光谱（280 nm-2800 nm）、可见光谱（400 nm-750 nm）和紫外光谱（290 nm-400 nm）三种光谱对光学环境进行了检测。照射时间为19：30 ~ 22：30，照射后30 min内，平均动脉压、最大dp/dt和心率均显著升高，随后逐渐下降。在太阳光谱、可见光谱和紫外光谱这三种光谱中也观察到了类似的变化。此外，在用小波变换分析计算最大dp/dt变化时，观察到约0.016Hz的特征变化，表明存在受光照射刺激的调节机制。这种反应同样可以用紫外线进行。
