Neutron irradiation causes damage of hemapoietic organs changing their morphological structure already in the first hours after irradiation. The damage is further intensified reaching its maximum on 3rd day. Recovery of the hemopoiesis in the bone marrow and spleen begins approximately on 5th day being complete by 15th to 21st day after irradiation. Continuous gamma irradiation for 10.5 days following single neutron irradiation (total accumulated dose of 6 Gy, daily input dose of 0.574 Gy) results in prolonged inhibition of the hemopoietic activity until termination of the irradiation. Reparation of the damaged bone marrow is seen only on about day 5 after cessation of continuous irradiation; this implies that continuous irradiation following neutron irradiation delays the onset of reparative processes by approximately 5 days.

In centre there are differences in the capacity for recovery from sublethal radiation injury and in repopulation. Chronically reacting normal tissues show a clearly higher repair capacity than tumors, that can be used for hyperfractionation with reduced single doses. With it higher attention must be given to repairing time yet, that the selective benefit is not endangered by incomplete recovery. On the other side clinical analyses have confirmed that the stem cell repopulation--going on in several tumor types, so e.g. in squamous cell carcinomas, during the time of conventional treatment--can make a considerable contribution to radioresistance. The actual level of knowledge justifies further clinical experiments with unconventional fractionation, especially with accelerated hyperfractionation.</p>","PeriodicalId":76404,"journal":{"name":"Radiobiologia, radiotherapia","volume":"30 3","pages":"181-92"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13813472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
