[The lysosomal acid phosphatase activity of the peripheral blood neutrophils of women in the dynamics of the menstrual cycle].
During menstrual cycle of women, the intensity of fluorescence of acid phosphatase (IAF) was registered in lysosomes from peripheral blood neutrophils after staining with Acridin orange. It has been shown that such integral values as criterion of agreement (chi(2)) and information entropy by Shennon (h) are most informative values of IAF. It is suggested that the dynamics of chi-square and h in menstrual cycle reflects changes in enzymatic activity, and is associated with destroying the ovum utilizing the products of its lysis.
