Thymidine Degradation Products in Plant Tissues Labeled with Tritiated Thymidine
A study of the metabolic pathways of H(3)-thymidine utilization in buds of Lilium longiflorum and root tips of Vicia faba was undertaken in order to obtain information that might explain the binding of H(3) from H(3)-thymidine in the cytoplasm of these plants. H(3)-thymidine was administered for various periods of time, the tissues were fixed and processed in the manner routinely used in prepar...
متن کاملAnalysis of Cytogenesis in Chick Retina by Tritiated Thymidine Autoradiography.
Differentiation of nerve cells and other elements in the developing central nervous system has been studied histologically in materials stained by various techniques especially by silver impregnation. The time sequence of cellular transformation or cytodifferentiation have been deduced from the presence of transitional forms. However, the interpretation of the transitions in structure have alwa...
متن کاملCytological damage produced in the mouse testes by tritiated thymidine, tritiated water and x-rays.
Irradiation of the mouse testes was carried out using internally distributed tritium from injected tritiated thymidine and tritiated water and also using external whole body irradiation with 200 kVp X-rays. The inability of intermediate spermatogonia to divide twice and produce resting primary spermatocytes was used as a criterion of biological damage and the following conclusions were reached:...
متن کاملChromosome Pulverization in Micronuclei Induced by Tritiated Thymidine
Cultures of a pseudodiploid cell line (Don) of Chinese hamster origin were exposed to varying doses of tritiated thymidine (TdR-(3)H) for relatively long periods of time. In addition to previously observed chromosomal aberrations) such as breaks and reunions, a substantial number of interphasic cells with micronuclei and of metaphases associated with pulverized chromosomes was found; both pheno...
متن کاملEffect of tritiated thymidine on cell proliferation.
The effect of tritiated thymidine on the rate of entry of cells into mitosis was studied in mice; 1-5 /tc of tritiated thymidine (specific activity 5 c/mM) per g body weight did not alter the rate of entry. Other workers have reported an increased number of mitoses following administration of larger amounts of thymidine than those used in the present work; the suggestion is therefore made that ...
