title: [Experience of the use of histoautoradiography in vitro, using 3H-thymidine, for assessing the degree of radiation damage to rectal adenocarcinoma].
abstract: In vitro thymidine histoautoradiography was employed to measure labeling index in 18 moderately- and well-differentiated adenocarcinomas of the rectum before and after radiotherapy. After radiation labeling index fell from 13.8 +/- 3.2 to 3.9 +/- 1.4% while mitotic index--from 8 to 1%.
