Action of thyroxine on functions of the sarcoplasmic reticulum of rabbit skeletal muscles

: A comparative study was made of the percentage of cells bearing the receptor for the third component of the complement (LRC) and of the total cell content in the rat lymphoid organs as related to the time course of cancerogenesis. It was shown that impairment of the maturation processes in the thymus and in the peripheral organs (lymph nodes, blood) of the immunocompetent systems produces changes in intercellular interactions, reflected by accumulation of B cells, i. e. LRC, and their delayed maturation to antibody producers.
