| Abstract: | A study was made of the effect of cholera vibrio neuraminidase and mouse interferon on the development of Rauscher's leukemia in BALB/c mice. It was shown that administration of 1500 units interferon to mice 4 hours before and 5 days after inoculation of Rauscher's leukemia virus prolonged the animals' lifespan. Preliminary treatment of the virus-containing material with neuraminidase prevented the death of one third of the experimental animals. Meanwhile the remainder of the animals inoculated with the same virus showed a longer lifespan. Combined use of both the preparations proved the most effective, enabling the prevention from death of 90% of the experimental animals. The mechanism of antiviral action of neuraminidase and interferon is discussed. |
