本文报导白品红和白对品红的致癌作用。白品红(试验用的为《白品红异构体》)是红紫色颗粒,主要成分含量78%。白对品红是红紫色粉末,主要成分含量98.7%。实验用雌雄大鼠和纯种小鼠。白品红异构体用雄性C3HA小鼠,白对品红用雌雄CC57Br小鼠。给药方法分为灌胃(每周5次),皮下注射(每周1次),皮肤涂敷(小鼠,每周2～3次)。白对品红给大鼠注射一次为25mg,小鼠为10mg;灌胃5mg;涂敷2mg。白品红异构体给大鼠注射一次为25mg,小鼠2mg。给药一直持续到动物死亡为止。结果表明:(1)大鼠皮下注射白对品红出现第一
This article reports the carcinogenic effects of white magenta and white on magenta. White mahogany (tested for “white magenta isomer”) is a magenta granule with a 78% major ingredient. White magenta is purple powder, the main ingredient content of 98.7%. Experimental male and female rats and purebred mice. Male C3HA mice were used for the white matter isomer and male and female CC57Br mice were used for the white magenta. Methods of administration are divided into gavage (5 times a week), subcutaneous injection (once a week), the skin coated (mice, 2 to 3 times a week). White magenta injection to rats once for 25mg, mice for 10mg; gavage 5mg; coating 2mg. The white matter isomer was injected once to rats 25mg, mice 2mg. Dosing continued until the animal died. The results showed that: (1) rat subcutaneous injection of white magenta appeared first
