SpletSince it has been well established that virgin T and B cells are highly radiosensitive, these cells were once assumed to be a unique lymphocyte population for which radiosensitivity does not follow the general law of radiation sensitivity for mammalian cells (Bergonie-Tribondeau law). SpletThe law of Bergonie and Tribondeau was found to have a very uniform application and stated that tumors composed of rapidly multiplying cells, especially those of embryonal type and particularly those of the lymphoid group, are highly susceptible to radiation, and in such ratio as the above characters are developed.
RADIOSENSITIVITY AND RATE OF CELL DIVISION:
SpletThe Law of Bergonié and Tribondeau • Stem cells are radiosensitive. The more mature the cell the more sensitive. • The older the tissue or organ, the more radiation resistant it is. • The lower the metabolic activity, the higher the resistance. • The radiosensitivity increases with the proliferation rate and growth rate. Splet27. jan. 1987 · the "Law of Bergoniè and Tribondeau". One exception to this law is mature lymphocytes, which are highly radiosensitive. Based upon these factors, it is possible to rank various kinds of cells in descending order of radiosensitivity. Most sensitive are the white blood cells called lymphocytes, followed by immature red blood cells. お風呂 サウナ やり方
RADIATION BIOLOGY - Nuclear Regulatory Commission
Splet(Law) a rule or set of rules, enforceable by the courts, regulating the government of a state, the relationship between the organs of government and the subjects of the state, and the relationship or conduct of subjects towards each other 2. (Law) a. a rule or body of rules made by the legislature. See statute law b. SpletExperimentation led to the law of Bergonie and Tribondeau which states that radiosensitivity is highest in tissues with a high mitotic index. Other scientists from this time described the dependence of radiation response to oxygen. Further advancement in radiation production equipment and computer assisted treatment planning then occurred. SpletLaw. (right; in Russian, pravo), the aggregate of generally binding rules of conduct established or sanctioned by a state, the observation of which is ensured by state enforcement actions. Law allows the class or classes controlling state power to regulate the behavior of individuals and groups in a particular way. お風呂 サウナグッズ
