Na. Karnaukhova et al., A correlation between the number and quality of immunocompetent animal cells and variations in solar activity, BIOFIZIKA, 44(2), 1999, pp. 313-317
It is shown that the number and quality (synthetic activity) of immunocompe
tent cells in animal peripheral blood correlate with the parameters of sola
r activity (number of spots on the Sun and solar fluctuations).
