[Circadian rhythms and aging].
The cosinor method was used to study the circadian variations in 36 haematic parameters in apparently healthy elderly subjects. A nyctohemeral cycle was evident in most cases. Differences in the means and range of IgA, IgG and antithrombin III rhythms compared to those of younger adults were noted. On the whole, the circadian system of the elderly is very similar to that of adults.
