[Continual observation of clinical and immunological parameters, in particular of salivary IgA, in tonsillectomised children (author's transl)].

In 106 tonsillectomised children the following parameters were measured before and after operation: clinical parameters (length, weight, postoperative complications), haematological parameters (BSR, Hg, PVC, RBC and WBC), and immunological parameters (IgG, IgA, IgM and salivary IgA); in a number of children measurements were taken over a period of more than three years. Standard values of salivary IgA in relation to total salivary protein were determined in non-infected children of various age groups. Compared with the standard and initial values we found some statistically significant changes in the serum immunglobulin levels and in the salivary IgA, but no irreversible pathological decrease in the above-mentioned parameters.
