When heavy cigarette smoking was first indicted as the major cause of the radical increase in lung cancer, scarcely more than 1% of cigarettes had filter tips. Today at least 40% have them, and tobacco experts expect the figure soon to hit 75%. But do the filters help? Up to now. the cynical answer has been that they help to sell cigarettes, and nothing more. Last week a congressional committee* opened an investigation of cigarette filters, for which the public pays a premium of $500,000 a day. Weight of the evidence: there is hope in improved filters...
...smoke less than a pack a day run a markedly reduced risk of lung cancer (compared with the much higher risk for those who smoke two packs or more). So, Dr. Ernest L. Wynder of Manhattan's Sloan-Kettering Institute told the committee, a filter that stops 40% or more of tar from a regular cigarette made of good tobacco "will be a partial answer." But during the five-year boom in filters, no such tip has been marketed. Testified Dr. Wynder: "Some companies have taken advantage of the public's desire for filtered cigarettes and its equal...
Added-"Easy Draw." Wynder's and other laboratory studies have shown that most filter-tip brands are as bad as. in many cases actually worse than, old-fashioned untipped cigarettes of regular length, because 1) the filters catch only a minimum of tar. and 2) to get the flavor through the filter, the manufacturers have taken to using stronger tobacco, which produces more...
...Brigham currently is in the field of transplants. Since few patients are lucky enough to have identical twins handy as donors, Surgeon Francis Moore is working on ways of getting grafts to take between unrelated individuals. In animals, his team has had some success by erecting a "filter barrier" around grafted glands, protecting them from the recipient's antibodies. On the basis of such studies, Dr. James B. Dealy Jr. predicted last week that the time is not far off when a replacement organ will be transplanted into an ailing human being with little more difficulty than" it takes...
...microwave communications. Now Hycon-Eastern is a contractor as well, has a $14 million contract to build a complete radio, telephone and TV communications network for Libya, is surveying a similar job in Thailand, dickering for contracts in Iran and the French Cameroons. The company has a crystal lattice filter for radios that will handle much higher frequencies at one-thousandth the cost of previous crystal lattice filters, has also developed an electronic time standard that varies but one second in 30 years. With first-year sales of $3,000,000, it expects to top $10 million...
