All of our figures are original and not copies of the work by Karchev and Kabakchiev as Konstantinov and Golemanov appear to suggest. In 1989, Fujiyoshi et al,2 in an article we were unaware of at the time ours was published, studied several functional aspects of the nasopharyngeal tonsil that included uptake of horseradish peroxidase by nonciliated cells in
