Abstract: | The influence of preparations obtained from oat and wheat seedlings (immunostimulating factors IF-1 and IF-2, respectively) on the natural resistance of mice to P. aeruginosa infection was studied. IF-1 and IF-2 were introduced intraperitoneally in a single injection in doses of 100 micrograms and 1000 micrograms per mouse 2 and 7 days prior to the inoculation of P. aeruginosa strain 8 in doses of 1 and 10 LD50. The presence of substances capable of stimulating the immunobiological reserves of the body in actively growing plants (seedlings) was shown. |
