title: [C-cell hyperplasia in the thyroid of the normal rat].
abstract: During life of normal rat, it appears an hyperplasia of thyroïdeal C cells, eventually till tumors, a progressive hypertrophy of parathyroïd glands and a fall of calcemia. Chronological study of these phenomena shows that C cells hyperplasia precedes parathyroïd hypertrophy. This last so appears as a reaction against hypocalcemia provoked by hyperplasia of parafollicular cells.
