...KR (for its discoverers' initials) is derived from Schizatrypanum cruzi, a South American trypanosome that has an affinity for cancer cells. When injected into cancerous mice, it gradually dissolves their tumors, but also kills the mice. Roskin & Klyueva developed a toxin from killed trypanosomes that dissolved cancer cells but was harmless to healthy cells. The cancer-destroying element, they concluded, was not the trypanosome itself but a toxin which it secreted. The toxin has proved safe for human patients...

Suspecting that it was not the parasites themselves which attacked the giant cells, but an unidentified chemical which they secreted. Dr. Roskin called in his wife. A Moscow University microbiologist named Nina Klyueva, she developed a solution from inactivated trypanosomes -KR for the two doctors' initials. Tests proved that the KR solution cured cancer implanted in mice, but did not harm healthy mice. To make sure that it had no ill effects on human beings, Dr. Roskin injected himself with the solution...
...very limited supply of KR has permitted, clinical tests have also been made on human cancers (i.e., where the growths were not so large that their dissolution would cause malfunctions). One inoperable throat cancer, Drs. Roskin & Kluyeva report, disappeared in two weeks. In an unspecified number of other cases KR "reduced" or partially destroyed cancer. But a lot more evidence is needed, the doctors admit, before the usefulness of KR can be safely evaluated...
