title: [Determination of biologic aging within the scope of the Halberstadt Gerontologic Study. 5. Correlation of physiologic parameters with calendar and biologic age. 1. Relative cell number of peripheral B and T lymphocytes].
abstract: There can occur considerable differences between the individual chronological age and the biological (functional) age of individuals. The relationship between chronological age, biological age and the relative number of T- and B-lymphocytes is examined. Whereas the number of B-lymphocytes does not show a dependence of biological age, the number of T-lymphocytes shows significant modifications dependent of biological age.
