[Radioautographic analysis of from peripheral blood and a focus of inflammation in amphibia]

In the peripheral blood of intact amphibians the cells of big lymphocyte type (light-nuclear forms) only are capable to incorporate 3H-thymidine. The implantation of foreign bodies in the subcutaneous lymphatic sac of R. temporaria induced the appearance in the circulating blood of one more cell form (dark-nuclear cells) capable of DNA synthesis. The autoradiographic analysis of interrelations between these forms allows to consider them as stages of one histogenesis.
