[The characteristics of proliferation activity in squamous metaplasia and reserve cell hyperplasia of uterine cervix].

The aim of our study was to investigate the characteristics of proliferation activity in squamous metaplasia and reserve cell hyperplasia of uterine cervix. Four groups of patients were selected: 1st group--34 reproductive patients with reserve cell hyperplasia, 2nd group--21 reproductive patients with squamous metaplasia, 3rd group--12 postmenopausal patients with reserve cell hyperplasia, 4th group--29 postmenopausal patients with squamous metaplasia. These groups included the patients with and without infections. Cervical biopsies were studied by immunohistochemistry using anti-Ki-67 monoclonal antibody. Ki-67(+) reserve cells were counted in reserve cell hyperplasia. Ki-67(+) squamous cells were counted in squamous metaplasia. The results showed that in both squamous metaplasia and reserve cell hyperplasia the number of Ki-67(+) cells, i.e. the intensity of proliferation is depended on the co-existence of infection, as well as on the age of the patient. These data are important in the complex treatment of cervical pseudoerosions.
