PREPARE SERUM FOR PNEUMONIA OF USUAL TYPE
Laboratories Develop Virus To Control 9 Cases Out of 10.
By Science Service NEW YORK, Dec. 20. — Life-sav-ing serum for treatment of upward of 90 per cent of all pneumococcus pneumonia cases will be available after the first of year. This is the promise seen iff.the announcement by the Lederle Laboratories, Inc., here that serum for Type III pneumonia will. go on the market in January. Serum for treatment of Types I, II, V, VII and VIII pneumonia are already available. These together with Type III pneumonia make up the bulk of all pneumococcus pneumonia cases. Cases of others of the thirty-two types of pneumonia are SO rare as to be considered medical curiosities, Manufacture of the new Type III serum, effective in a pneumonia that kills from 60 to 80 out of every 100 patients, is possible because of researches at the Rockefeller Institute for Medical Research which showed that rabbit blood could be used instead of horse blood for manufacture of pneumonia serum. The life-saving results of the new serum, as well as of the others now available, depend on early, accurate diagnosis of the ailment in each case. Medical and health authorities stress the importance of having facilities available everywhere make the laboratory tests which show what type of pneumonia a particular patient suffers from. It does no good and may do harm to give a patient Type III serum, for example, if he is sick with Type II pneumonia. The serums are only effective in the particular types of ‘ pneumonia for which they are made.
Cancer-Producing Chemicals Studied
By Science Serviee CAMBRIDGE, Mass., Det. 20.—A clearer definition of the essential structural features of cancer-pro-ducing chemicals, one more step in
science’s many-fronted fight to conquer the disease, has been made in the Converse Memorial Labora-
tory at Harvard University by Prof. |
Louis F. Fieser and his associates.
While the important problem of determining the exact manner in which these chemicals initiate malignant growth is still unsolved, scientists feel that this progress may clarify their understanding of the chemicals and help point the way to an eventual solution. Three years ago Prof. Fieser accomplished the synthetic production of methylcholanthrene, a complex and very powerful cancer-producing hydrocarbon. This compound can also be obtained chemically from the bile acids of the human body. : Since that time Prof. Fieser and his research group have synthesized 68 new chemical compounds, all of them similar to methylcholanthrene but each with small structural differences. These have been injected into mice in an attempt to learn why methylcholanthrene is so powerful and how its acts on living cells. Experiments now completed show that 22 of these new compounds definitely produce cancer and that 19 definitely do not. The fact that methylcholanthrene can be chemically obtained from the bile acids, Dr. Fieser points out, gives strong support to the possibility that cancer might result from abnormal metabolism that leads to the .formation of some

hydrocarbon of the methylcholanthrene type within the body. This idea is also supported by
what Dr. Fieser terms “the striking | |
circumstance that this particular hydrocarbon—which carries as a mark of its possible origin the fivemembered ring - characteristic of sterols and sex hormones—is very potent.” Since any investigation of the biological formation of methylcholanthrene by direct experimentation is not yet possible, these circumstantial lines of evidence are very important.
Seek to Increase Phone Cable Range
By Science Service NEW YORK, Dec. 20.—Bell Telephone Laboratory engineers will shortly begin removing the “repeaters” from their experimental coaxial cable between New York and Philadelphia in order to install equipment which will widen the band carried by the cable from one million to two million frequencies, Paul B. Findley, Bell Laboratories Record managing editor, revealed here. The 36 communication channels, arranged in three groups of 12 each, available on the present cable within the 1,000,000 cycle it can carry will be able to be placed anywhere within the 2,000,000 cycle range when the new installation is finished, he stated. The cable, which is really a wire inside a metal tube; is capable of transmitting either nearly 3000 dot-
and-dash messages or 240 telephone | |
messages simultaneously. It can also
successfully handle a television|
transmission. Demonstrated recent-
ly, the cable is hailed as the single |
most important development in telephony since the introduction of “carrier telephony’ almost 20 years ago.
