In animals with a tumors are rised free radical processes,as stimulated forming

 for nitro connects are nitrates and nitrites in organism, as  for a calculating forming theirs in the tumor s tissue.Entering fungus for healthy animals as lead to rising a whole quantity cells in peritoneal contain, as for a calculation lymphocytes and macrophages.Entering fungus in mouses to induction of Ehrlich within a tumor grow as normalized a quality index of cells contain in peritoneal liquid and with this caused a clear activation for macrophages of peritoneal contain.
And found a lowering nitrites in peritoneal liquid of mouses with a tumors, that is a  investigation for suppressing of production of nitrogen oxide and theirs metabolites by macrophages and neutrophiles under effect producing a tumor are active connects. And earlier was evidenced,that nitrogen oxide,secreting by macrophages and neutrophiles is doing protection role,directing on the inactivation of foreign cells and tumor.And entering for supplement in maximal dose was corrected activity of macrophages on an index a forming of nitrogen oxygen to the level of cells activity in a healthy mouses.And about a forming nitrites and nitrates in tumor s tissue, that supplements are lowered contain for acidity products is nitrogen oxide in tumor.

The role of nitrogen oxide in the tumor grow is not ambiguous and not enough found out.
