本文通过动物实验。观察了心痛气雾剂对家兔和小白鼠的急性及亚急性毒性作用,并观察了本品对家兔离体心脏和在位兔心及血氧分压的影响。实验结果表明,本品具有扩张血管,增加离体心脏的冠脉流量,减少小白鼠在常压下的耗氧量。提高家兔与小白鼠的血氧分压,而心痛气雾剂无论是一天一次或一天二次经呼吸道吸入给药,连续吸入30天以上者,对家兔肺泡组织均呈程度不同的损害对离体心脏和在位心脏均表现一过性的
This article passes animal experiments. Observed the acute and subacute toxic effects of Xintong aerosol on rabbits and mice, and observed the effect of this product on isolated heart and rabbit heart and blood oxygen partial pressure in rabbits. The experimental results show that this product has dilated blood vessels, increased coronary blood flow in isolated hearts, and reduced oxygen consumption in mice under normal pressure. Raise the partial pressure of oxygen in rabbits and mice, and whether the pain relief aerosol is administered by inhalation once a day or twice a day and continuously inhaled for more than 30 days, the degree of damage to the alveolar tissue of rabbits is different. Both isolated heart and recumbent heart are transient
