Ultradians, including an about-8-hourly component, and a prominent about-half-weekly wobbly band characterize the population density of endotheliocytes. Endotheliocytes in pinnal connective tissue – revealed by gliding spectral window periodogram as a contour map with consecutive 7-day intervals, displaced in 0.5-hour increments through a 10-day span of 3-hourly counts, made on presumably undisturbed C₅₇B₁ mice, before application of a trauma. Extension of circaoctohoran and 3.5-day (circasemiseptan) components in the endothelin-1 spectrum of the human circulation to the population density of murine endotheliocytes, the cells producing endothelin-1 (but not to the population density of other cells in the same ear pinna, not shown) [290].
