血清硫氰酸盐浓度是用于评价吸烟者吸烟程度的几种变量值之一。由于其生物半减期较长,值得采用。作者选择有6～20年吸烟史并决定彻底戒烟的健康男女各三人进行调查。男性34～36岁,每天吸烟20～30支;女性28～37岁,每天吸烟20～40支。于戒烟前的五天内测定最初的血清硫氰酸盐浓度一次,戒烟后采集每一受试者的禁食血样各4～5次进行测定,最后一次血样采自各人戒烟后的第26、30、35、38、39和44天。 Serum thiocyanate concentration is one of several variables used to assess the degree of smoking among smokers. Due to its long biological half-time reduction, it is worth using. The authors surveyed three healthy men and women who had a history of 6-20 years of smoking and decided to quit smoking altogether. Male 34 to 36 years old, 20 to 30 cigarettes a day; women 28 to 37 years old, 20 to 40 cigarettes a day. The initial serum thiocyanate concentration was determined within five days prior to smoking cessation, the fasted blood samples of each subject were collected 4 to 5 times after quitting smoking, and the last blood sample was taken from the 26th, 30, 35, 38, 39 and 44 days.
