...took 281 healthy white mice, implanted cancers under their right armpits by injections of tumor particles of mouse sarcoma 180. The spleen extract which he prepared to use was in high concentration. In most of the mice, hemorrhage then occurred at the cancer site. This was soon covered by a scab which in time was thrown off and the wound eventually healed. The cancer had disappeared, leaving no trace except a slight sparseness of hair over the region it once occupied. Five months after treatment there were no recurrences. In Surgery, Gynecology & Obstetrics last week Dr. Lewisohn gave the percentage...
...jurisprudence on this phase of the legal status of fetuses, to deny $100,000 damages to a Mrs. Theresa Joller Smith, who had sued Dr. Albert E. Luckhardt and Radiologist Isador Simon Trostler. Thirteen years ago, she claimed, Dr. Luckhardt diagnosed a lump in her abdomen as a tumor and the radiologist treated her with X-rays. The "tumor" turned out to be a baby whose head the X-rays had caused to harden unduly soon. Result was an imbecile who lived until last October...
...Ludwik Gross of the Pasteur Institute in Paris made small, weak doses of finely minced sarcoma tissue, injected them not beneath but in the skins of mice. In most of the animals metastases (cancer colonizations elsewhere in the body) took place and death followed. But in 10% the skin tumor caused by the injection dried up and disappeared and thereafter the mice were immune to that type of sarcoma. The percentage of tumor disappearances and subsequent immunities was doubled by barely pricking the freshly shaved skin with a needle which had been dipped in the cancer emulsion...
Even better results were obtained with rabbit carcinoma. When the rabbits were inoculated in the skin, the resulting tumors invariably disappeared and the animal was thereafter immune. It was evident that in the rabbit's blood some antibody had been generated which dried up the skin tumor and provided lasting protection. Similar experiments with chickens, however, failed...
...light on the failure with chickens was cast by Dr. William Ewart Gye, director of Britain's Imperial Cancer Research Fund, who found that even in the blood of chickens with growing cancers there may be antibodies in amounts detectable by chemical means. "A hen may carry a tumor," he wrote, "and have at the same time more than enough of the immune body in its circulating fluids to neutralize the whole of the virus in its tumor, and the tumor nevertheless continues to grow." The reason appeared to be that the cancer virus takes refuge inside the body...
