Infradian modulation of liver nucleic acid and lipid content of adult female Lewis/S rats

ABSTRACT

Infradian modulation with periods of 168 h and 120 h characterizes the RNA, DNA and lipid content of the liver in adult female Lewis/S rats. Multilinear analysis shwos that the fit of an infradian cosine curve with these periods is statistically significant below the 5% level (P = 0.011;P = 0.007 and P = 0.013) and that they account for 19.0, 22.7 and 20.1% of the overall variability, respectively
