[Rhythms of the number and secretory activity of mouse goblet enterocytes under adequate and inverted feeding regimens].
The autocorrelation function followed by the definition of spectral density showed the appearance of infradian, circadian and ultradian components of biorhythms of the total number and secretory activity (accumulation and release) of the small intestine goblet enterocytes in the basal, medium and apical portions of the villi. Biorhythm changes were also observed after the inverted feeding. After the inverted (ecologically adequate) feeding, the circadium component of the rhythms was revealed for almost all the indices. The ultradian rhythms formed four ranges; within each of them the ultradian components of biorhythms increased in frequency in the basal-apical direction. After the morning (inverted) feeding, the circadian component was found to decrease in its power for the majority of indices, while the ultradian oscillations became of more complex spectral composition.
