The girls before puberty and women of old age in the vaginal content is dominated by small, so-called atrophic cells with large nuclei and a small number of protoplasm is the first or the second reaction of colpocytology.
Bacterial flora content vagina diverse. Depending on its structure there are four degrees of purity vaginal contents. When the first degree of purity reaction content vagina sour, leukocytes are missing, vaginal Bacillus a significant amount of pathogenic microbes no; in the second degree of purity appear as a separate cells, vaginal Bacillus in moderation, of pathogenic microbes in small numbers; in the third degree of cleanliness has considerable quantity of leukocytes, dominated by pathogenic flora, vaginal sticks unit; at the fourth degree of purity in the content of the vagina many leukocytes, pathogenic flora.
