[Effect of the alimentary factor on the immunobiologic reactivity of children's bodies].

Observations covered 66 healthy six-year old children of a childrens' home. The actual alimentation of the children was studied according to tabulated values for one year and 112 apportionoments. In the rations of actual nutrition a disturbed correlation of proteins, fats and carbohydrates was noted. Seasonal variations of the salival lysozyme activity were revealed against the background of the actual alimentation. The lowest antimicrobial activity of the lysozyme was recorded in the winter and spring seasons of the year. The low lysozyme activity of the saliva in spring may be explained by deficiency of the animal protein in the ration. In winter time added to the insufficient content of the animal protein were features specific for the day's routine, typical of this season. An addition of the animal protein to the actual nutritional rations of the children, in the form of eggs and nonfat dry milk and a correction of the proteins, fats and carbohydrates proportions in the rations led to a statistically significant rise in the lysozyme activity in the saliva of children during all the months of observation.
