本文研究接触蚊香烟雾的大鼠呼吸系统的组织学改变和血清酶的变化。将40只一月龄雌性Spraque-DaWley大鼠分为两组,一组接触蚊香烟雾,每天持续8小时,每周6天,共60天。另一组为对照。蚊香选用香港最流行的牌子。吸入室体积为22.5m~3,并装有空气调节器,流量为22.5m~3/h。除染毒时间外,大鼠可随意进食和饮水。每周称
This article studies the histological changes of respiratory system and changes of serum enzymes in rats exposed to mosquito coils. Forty one-month-old female Spraque-DaWley rats were divided into two groups. One group was exposed to mosquito-repellent tobacco smoke for 8 hours a day for 6 days a week for 60 days. The other group is a control. Mosquito coils use Hong Kong’s most popular brands. Inhalation chamber volume 22.5m ~ 3, and equipped with air conditioners, the flow rate of 22.5m ~ 3 / h. In addition to exposure time, rats are free to eat and drink water. Weighing every week
