The morphology of a muscular component of myometrium of primipara women with physiological contractile activity

Conducted quantitative light-optical study of structures of biopsy samples of myometrium taken from 5 primiparas aged 21-38 years with physiological contractile activity. It was shown that the smooth muscle cells had different affinity to toluidine blue and were conditionally divided into light, dark and intermediate cells. Estimated the following parameters: the number of smooth muscle cells on 1 mm2 of myometrium, the percentage ratio of each types of muscle cells and cellular diameters. All estimated components have had intergroup variations. Results of this research can be used for comparative analysis of the same parameters in women with pathological contractile activity.
