AZT, the only drug approved for widespread use against the AIDS virus, can cause cancer in animals at very high doses, according to the results of a study mailed out to physicians Tuesday by the drug's manufacturer. The study, conducted by Burroughs Wellcome Co. and required for all drugs on the market, found that some mice and rats given the highest doses of AZT for many months developed vaginal tumors toward the end of their life span.

Seven activists protesting the high cost of an AIDS drug Thursday chained themselves to a railing at the New York Stock Exchange as the opening bell signaled the start of trading but were quickly unshackled and arrested, police said. The activists, affiliated with the known as ACT-UP, told officials that they were protesting the refusal of Burroughs Wellcome Co. to lower the price of AZT, a drug used to treat AIDS.
